Treatment of gingival recession has become an important therapeutic issue due to increasing cosmetic demand. Multiple surgical procedures have been developed to obtain predictable esthetic root coverage. More specifically, after periodontal regenerative surgery, the aim is to achieve complete wound healing and regeneration of the periodontal unit. A recent innovation in dentistry is the preparation and use of platelet-rich plasma (PRP), a concentrated suspension of the growth factors, found in platelets. These growth factors are involved in wound healing and postulated as promoters of tissue regeneration. This paper reports the use of PRF membrane for root coverage on the labial surfaces of the mandibular anterior teeth. This was accomplished using laterally displaced flap technique with platelet rich fibrin (PRF) membrane at the recipient site.

Nitric oxide (NO) is not only important in host defense and homeostasis but it is also regarded as harmful and has been implicated in the pathogenesis of a wide variety of inflammatory and autoimmune diseases. The presence of NO in periodontal disease may reflect the participation of an additional mediator of bone resorption responsible for disease progression. The aim of this study was to assess the level of NO in serum in chronic periodontitis, and correlate these levels with the severity of periodontal disease. Sixty subjects participated in the study and were divided into two groups. NO levels were assayed by measuring the accumulation of stable oxidative metabolite, nitrite with Griess reaction. Results showed subjects with periodontitis had significantly high nitrite in serum than healthy subjects. NO production is increased in periodontal disease, this will enable us to understand its role in disease progression and selective inhibition of NO may be of therapeutic utility in limiting the progression of periodontitis.

The human characteristics of curiosity, wonder, and ingenuity are as old as mankind. People around the world have been harnessing their curiosity into inquiry and the process of scientific methodology. Recent years have witnessed an unprecedented growth in research in the area of nanoscience. There is increasing optimism that nanotechnology applied to medicine and dentistry will bring significant advances in the diagnosis, treatment, and prevention of disease. Growing interest in the future medical applications of nanotechnology is leading to the emergence of a new field called nanomedicine. Nanomedicine needs to overcome the challenges for its application, to improve the understanding of pathophysiologic basis of disease, bring more sophisticated diagnostic opportunities, and yield more effective therapies and preventive properties. When doctors gain access to medical robots, they will be able to quickly cure most known diseases that hobble and kill people today, to rapidly repair most physical injuries our bodies can suffer, and to vastly extend the human health span. Molecular technology is destined to become the core technology underlying all of 21
st
century medicine and dentistry. In this article, we have made an attempt to have an early glimpse on future impact of nanotechnology in medicine and dentistry.

PMID
:20922077
Background:
Gingival retraction methods are used in dentistry for impressions of subgingival crown margins, such as, mechanical, chemical, chemicomechanical, and surgical. These methods may injure the gingival sulcular epithelium. Hence, the present study is carried out to evaluate the effect of different retraction materials, such as, Expasyl, Magic Foam Cord, and impregnated retraction cord on the gingival sulcular epithelium.
Materials and Methods:
This study included 30 cases of bilateral premolar extraction patients with Loe and Silness gingival index zero. Retraction materials were kept in the dry, isolated labial gingival sulcus for the required time. The retraction materials were removed by rinsing with water. Retracted gingiva of 2 - 3 mm from the gingival margin along with the tooth was extracted and the decalcified sections were microscopically studied.
Data analysis:
Data were analyzed by applying the chi-square test.
Results:
This study showed better results with retraction paste as compared to the retraction cord, and there was a significant association between retraction materials and the relative degree of injury to the sulcular epithelium.
Conclusion:
There is a significant association between retraction materials and gingival sulcular epithelium. It can be stated that impregnated retraction cord, may be used commonly but it needs proper tissue manipulation and is technique sensitive. Newly advanced material in the form of retraction paste like Expasyl or Magic Foam Cord was found to be better than cord as assessed histologically, it respects periodontium.

SHORT COMMUNICATION
Nicotine and periodontal tissues
Ranjan Malhotra, Anoop Kapoor, Vishakha Grover, Sumit Kaushal
January-March 2010, 14(1):72-79
DOI

PMID
:20922084
Tobacco use has been recognized to be a significant risk factor for the development and progression of periodontal disease. Its use is associated with increased pocket depths, loss of periodontal attachment, alveolar bone and a higher rate of tooth loss. Nicotine, a major component and most pharmacologically active agent in tobacco is likely to be a significant contributing factor for the exacerbation of periodontal diseases. Available literature suggests that nicotine affects gingival blood flow, cytokine production, neutrophil and other immune cell function; connective tissue turnover, which can be the possible mechanisms responsible for overall effects of tobacco on periodontal tissues. Inclusion of tobacco cessation as a part of periodontal therapy encourages dental professionals to become more active in tobacco cessation counseling. This will have far reaching positive effects on our patients' oral and general health.

Periodontitis is a chronic inflammatory disease of the tooth-supporting structures. The treatment of this condition is largely based on the removal of local factors and restoration of the bony architecture. Moreover, in the era of modern dentistry, successful implant therapy often requires sound osseous support. Traditionally, osseous surgery has been performed by either manual or motor-driven instruments. However, both these methods have their own advantages and disadvantages. Recently, a novel surgical approach using piezoelectric device has been introduced in the field of periodontology and oral implantology. This article discusses about the wide range of application of this novel technique in periodontology.

Background
: Diabetes mellitus is a systemic condition that has long been associated with an increased risk and severity of periodontal disease. Polymorphonuclear leukocytes (PMNs) play a key role in the maintenance of gingival and periodontal health. Reduced PMN function has been found in patients with diabetes.
Aim:
The objective of this study was to evaluate PMN functions in 15 diabetic patients with chronic generalized periodontitis.
Materials and Methods:
Chemotaxis, superoxide production, phagocytosis and killing of
Porphyromonas gingivalis
by diabetic PMNs were evaluated relative to healthy and matched controls.
Results:
These analyses revealed a significant (
P
< 0.01) depression in the number of diabetic PMNs migrating along an fMLP gradient. In addition, a significant (
P
< 0.01) enhancement of diabetic PMN superoxide production was observed. Phagocytosis (
P
< 0.05) and killing by diabetic PMN of
P. gingivalis
was also impaired significantly (
P
< 0.01).

The challenge of antioxidants to free radicals in periodontitis
Gowri Pendyala, Biju Thomas, Suchetha Kumari
September-December 2008, 12(3):79-83

Periodontal disease is a chronic adult condition. Bacteria implicated in the etiology of this disease causes destruction of connective tissue and bone. As a result of stimulation by bacterial antigen PMN produces free radicals via respiratory burst as a part of host response to infection. Patients with periodontal disease display increased PMN number and activity. This proliferation results in high degree of free radical release culminating in heightened oxidative damage to gingival tissues, periodontal ligament and alveolar bone. Damage mediated by free radicals can be mitigated by "ANTIOXIDANT DEFENSE SYSTEM ". Physiological alteration and pathological states produced by free radicals depend on disequilibrium between free radical production and antioxidant levels leading to oxidative stress. Hence this study has been designed to estimate the TOTAL ANTIOXIDANT CAPACITY in patients with PERIODONTITIS and healthy control subjects

Talking about periodontic-orthodontic interrelationships is related primarily to the 1960s, where a generalized increase in salivary bacterial counts, especially Lactobacillus, had been shown after orthodontic band placement. The purpose of this article is to provide the dental practitioner with basic understanding of the interrelationship between periodontics and orthodontics by means of representing classical studies, and, to give an update on this topic by demonstrating the most recent opinions concerning periodontic-orthodontic interrelationships. Specific areas reviewed are the ability of orthodontic treatment to afford some degree of protection against periodontal breakdown, short-term and long-term effects of orthodontic treatment on the periodontium, and some mucogingival considerations. Topics considering orthodontic treatment in periodontally compromised patients were not included in this review. While past studies have shown that orthodontic treatment can positively affect the periodontal health, recent reviews indicate an absence of reliable evidence for the positive effects of orthodontic therapy on patients' periodontal status. Periodontic-orthodontic interrelationships are still controversial issues. However, a standard language between the periodontist and the orthodontist must always be established to eliminate the existing communications barrier, and to improve the outcomes of the whole treatment.

PMID
:20376233
Aims and Objectives
: Anemia of chronic disease (ACD) is one of the most common forms of anemia. It is defined as anemia occurring in chronic infections, inflammatory conditions or neoplastic disorders which are not due to marrow deficiencies or other diseases, and occurring despite the presence of adequate iron stores and vitamins. Periodontitis is one of the most prevalent chronic inflammatory diseases in humans. This study aimed at finding out if periodontitis, like other inflammatory conditions, could lead to anemia.
Materials and Methods
: Thirty chronic generalized periodontitis male patients with hemoglobin levels below 15 mg/dl and serum ferritin values above 30 ng/ml were selected. The various blood parameters recorded at baseline were hemoglobin levels(Hb), erythrocyte count (RBC), erythrocyte sedimentation rate (ESR), mean corpuscular volume(MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC). Periodontal parameters recorded at baseline included: plaque index, gingival index, probing pocket depth, clinical attachment level. Periodontal treatment including surgery if required was carried out in all the patients. Periodontal status of patients was monitored by repeating evaluation of periodontal indices at three months and at the end of one year. The hematological values were again measured at the end of one year.
Results:
The results showed that correction of periodontal inflammation resulted in a significant increase in hemoglobin levels and erythrocyte counts. The erythrocyte sedimentation rate showed a reduction indicating resolution of periodontal inflammation. There was a significant, but much lesser, improvement in MCV, MCH and MCHC values.
Conclusion:
The results of this study showed that treatment of periodontitis leads to an improvement in hematocrit and other related blood parameters in chronic generalized periodontitis patients with anemia. This provides evidence that periodontitis like other chronic diseases may also cause anemia.

Dhruva Kumar Gani, Deepa Lakshmi, Rama Krishnan, Pamela Emmadi
May-August 2009, 13(2):69-74
DOI
:10.4103/0972-124X.55840
PMID
:20407653
Aims and Objectives:
The aim of the present study was to investigate systemic levels of inflammatory markers of cardiovascular diseases like C-reactive protein and interleukin-6 in patients with chronic periodontitis, in comparison to periodontally healthy individuals.
Materials and Methods:
A total of 42 individuals, both males and females above the age of 30 years, were included in the study. Healthy controls (Group I,
n
= 14), chronic localized periodontitis (Group II,
n
= 14), and chronic generalized periodontitis (Group III,
n
= 14), all without any medical disorder, were recruited. Peripheral blood samples were taken and C-reactive protein (CRP) levels were estimated in the serum samples by using the Particle-Enhanced Turbidimetric Immunoassay (PETIA) technique. Serum samples of Interleukin-6 (IL-6) were assayed by using the Chemiluminescent Immunoassay (IMMULITE) technique.
Results:
When mean CRP levels were compared between the groups, group III showed statistical significance when compared to group I (
P
= 0.04). Group III had a higher median IL-6 level (6.35 pg/mL) than Group II (< 5.0 pg/ mL) and group I (< 5.0 pg/mL). Differences in median values of IL-6 were not statistically significant in any group (
P
= 0.29).
Conclusion:
Periodontitis results in higher systemic levels of CRP and IL-6. These elevated inflammatory factors may increase inflammatory activity in atherosclerotic lesions and potentially increasing the risk for cardiovascular events.

Biju Thomas, Suchetha Kumari, K Ramitha, MB Ashwini Kumari
January-March 2010, 14(1):46-49
DOI
:10.4103/0972-124X.65439
PMID
:20922079
Background:
Periodontal diseases are microbial induced chronic inflammatory conditions characterized by infiltration of leukocytes, loss of connective tissue, alveolar bone resorption, and formation of periodontal pockets. In response to periodontal pathogens, the leukocytes (PMN) elaborate destructive oxidants, proteinases and other factors. The balance between these factors, the antioxidants and endogenously synthesized antiproteinases determine the extent of periodontal damage. Diabetes mellitus is a metabolic disorder. Most of the complications of diabetes are due to hyperglycemia. Persons with diabetes are at a greater risk for periodontal disease Malnutrition is characterized by marked tissue depletion of antioxidant nutrients and impaired acute phase protein response to infections resulting in impaired healing. Diabetes mellitus also alters the micronutrient levels. Malnutrition is characterized by marked tissue depletion of antioxidant nutrients and impaired acute phase protein response to infections resulting in impaired healing. Malnutrition, which usually involves concomitant deficiencies of several essential macro and micro nutrients, therefore, has the potential to adversely influence the prognosis of periodontal infections. Objectives:This study has been conducted to evaluate and compare the serum levels of vitamin C, zinc and copper in diabetic and healthy individuals with periodontitis.
Materials and Methods:
In this case control study 60 subjects inclusive of both sexes were selected and divided into 3 groups of 20 each. Group 1 comprised of 20 subjects with type 2 diabetes mellitus and periodontal disease, Group 2 comprised of 20 healthy subjects with periodontal disease. And Group 3 comprised of 20 healthy subjects without periodontal disease. Venous blood samples were collected and centrifuged at 3000rpm for 15 minutes and the superanatant serum is collected to measure the vitamin C, zinc and copper levels. The vitamin C levels of clinical samples were measured using spectrophotometric quantitation (dinitrophenyl hydrazine method) and zinc and copper levels were measured using atomic absorption spectrophotometry.
Results:
The results showed that the levels of vitamin C and zinc decreased and copper levels increased in diabetic patients with periodontits compared to healthy individuals with periodontitis.
Conclusion:
It may be reasonable to suggest vitamin and/or mineral supplements for patients whose nutrition might be inadequate. Future research should focus on an evaluation of which nutrients may help to prevent the onset and progression of periodontal disease

Amlodipine-induced gingival overgrowth
MG Triveni, C Rudrakshi, DS Mehta
September-December 2009, 13(3):160-163

Gingival overgrowth represents an over-exuberant response to a variety of local and systemic conditions. Certain anticonvulsants, immuno-suppressive drugs and a number of calcium channel blockers have been shown to produce similar gingival overgrowths in certain susceptible patients. Amlodipine is a comparatively new calcium channel blocker and has been used with increasing frequency in the management of hypertension and angina. Although amlodipine is considered as a safe drug, very rarely it may induce gingival overgrowth also. A rare case of amlodipine-induced gingival overgrowth has been reported herein in a 50-year-old female patient. The treatment aspect included Phase-1 therapy, substitution of the drug, the surgical excision and the maintenance and supportive therapy resulting in excellent clinical outcome.

Snophia Suresh, T.S.S Kumar, PK Saraswathy, KH Pani Shankar
January-March 2010, 14(1):30-34
DOI
:10.4103/0972-124X.65434
PMID
:20922076
Aim:
The aim of the study was to assess the relationship between bone mineral density and periodontitis in premenopausal and postmenopausal women.
Materials and Methods:
Twenty women between the age group of 45-55 years were selected for this study. Ten premenopausal women with healthy periodontium constituted the control group and 10 postmenopausal women with ≥2mm of clinical attachment loss in >30% of sites constituted the study group. All patients were assessed for plaque index, probing depth and clinical attachment loss. Radiographs (six IOPA and two posterior bitewing) were taken and assessed for interproximal alveolar bone loss. The patients were scanned to assess the bone mineral density of lumbar spine (L2) and femur using dual energy X-ray absorptiometry (DEXA).
Results:
The bone mineral densities of lumbar spine (L2) and femur were significantly lower in the study group than the control group. Osteopenia of the lumbar spine and femur was observed in 60% whereas osteoporosis of lumbar spine was observed in 30% of cases in study group.
Conclusion:
Increased proportion of osteopenia and osteoporosis cases of lumbar spine and femur in postmenopausal women with periodontitis suggests that there is association between bone mineral density and periodontitis.

Aging is one of the major health challenges today. Most of the diseases related to aging, lead to significantly increased morbidity and mortality and higher public expenditure of funds. The interconnection between socio- economic conditions and social vulnerability is reflected in precarious states of health with prominence of high rates of osteoporosis and periodontal disease.Both these diseases have been highlighted in public health because of the impact caused by bone fracture and tooth loss. Thus, the elderly could help live a healthier and more meaningful life with the prevention of these diseases.

Evaluation of plasma C-reactive protein levels in pregnant women with and without periodontal disease: A comparative study
Anupriya Sharma, Amitha Ramesh, Biju Thomas
September-December 2009, 13(3):145-149
DOI
:10.4103/0972-124X.60227
PMID
:20379412
Background and Objectives:
Circulating C-reactive protein (CRP) levels are a marker of systemic inflammation and are associated with periodontal disease, a chronic bacterial infection associated with elevation of proinflammatory cytokines and prostaglandins. CRP has been associated with adverse pregnancy outcomes, including preterm delivery, preeclampsia, and intrauterine growth restriction. Furthermore, periodontal disease has been associated with increased risk of preterm low birth weight, low birth weight, and preterm birth. The present study was conducted to assess plasma CRP levels in pregnant women with and without periodontal disease; to evaluate the effect of periodontal therapy on the incidence of preterm delivery; and to compare the incidence of preterm delivery in pregnant women with and without periodontal disease.
Materials and Methods:
A total of 90 pregnant women aged between 18-35 years with gestational age between 12-28 weeks were recruited and divided into three equal groups (control group, study group, treatment group) of 30 each. Blood samples were taken for estimation of C-reactive protein levels from all groups at 12-20 weeks of gestation, determined using ultrasensitive turbidimetric immunoassay (QUANTIA-CRP US). The treatment group comprised plaque control, scaling, and root planning and daily rinsing with 0.2% chlorhexidine mouth before 28 weeks of gestation.
Results:
The mean value of C-reactive protein levels in subjects with periodontal disease was higher compared to control group i.e., 1.20 ± 0.247 mg/dl and 1.22 ± 0.250 mg/dl, respectively, compared to 0.713 ± 0.139 mg/ dl (
P
= 0.001). The mean value of CRP levels before treatment was greater than the mean value after treatment i.e., 1.22 ± 0.25 compared to 0.84 ± 0.189 (
P
< 0.001). The incidence of preterm delivery (< 37 weeks) was 31.7% in the periodontal disease group (study group) compared to 8.3% in the control group (
P
= 0.001). The incidence of preterm delivery in the treatment group was 15.0% compared to 31.7% in the nontreatment group (study group).
Conclusion:
The findings from the study suggest that periodontal disease in pregnant women is associated with increased C- reactive protein levels in early pregnancy, incidence of preterm delivery is higher in pregnant women with periodontal disease compared to healthy controls, periodontal therapy during pregnancy reduces plasma CRP levels and there is decrease in incidence of preterm delivery after periodontal therapy.

Immunohistological analysis of CD1a
+
langerhans cells and CD57
+
natural killer cells in healthy and diseased human gingival tissue: A comparative study
Sahaya Stelin, Hemalatha Ramakrishan, Avaneendra Talwar, KV Arun, T.S.S Kumar
September-December 2009, 13(3):150-154
DOI
:10.4103/0972-124X.60228
PMID
:20379413
Background:
Cell interaction between dendritic cells (DC) and natural killer (NK) cells in the periodontal milieu is not yet fully known, although these cells are individually known to contribute to the pathogenesis of periodontal disease.
Materials and Methods:
Fifty subjects (25 males and 25 females) were included in the study. The subjects were divided into three groups: Group A comprised 16 subjects with clinically healthy gingiva; group B 17 subjects with gingivitis; and group C 17 subjects with gingivitis; and group C 17 subjects with moderate periodontitis (PPD ≥ 5 mm and CAL ≥ 3 mm in at least six sites). Gingival samples were collected and immunohistochemical study was done using CD57 and CD1a antibody. Statistical analysis was done using analysis of variance (ANOVA), followed by Tukey-Kramer multiple comparison for CD1a and Tukey's highly significant difference (HSD) test for CD57.
Results and Conclusion:
The study showed an inverse relationship between the CD1a
+
(langerhans) cells and CD57
+
(natural killer) cells. There was a significant increase in CD57
+
cells and reduction in CD1a levels as periodontal disease progressed. The significant reduction in CD1a levels in periodontal disease when compared to health could possibly be a result of NK cells down regulating it. Reduction in CD1a levels may result in a low inflammatory response subsequently resulting in tissue destruction.

Evaluation of an aminobisphosphonate (alendronate) in the management of periodontal osseous defects
HR Veena, Deepak Prasad
January-March 2010, 14(1):40-45
DOI
:10.4103/0972-124X.65438
PMID
:20922078
Background and Objectives:
Alendronate, an aminobisphosphonate, is capable of inhibiting periodontitis associated osteoclastic activity and hence is effective in protecting the alveolar bone in periodontitis. In the present study, we explored the efficacy of local delivery of alendronate on the alveolar bone following mucoperiosteal flap surgery. This is the first study to use polymer impregnated gel based delivery of alendronate.
Materials and Methods:
A total of 15 patients with chronic periodontitis in the age group of 35 - 55 years, of both sexes, with pocket depth of ≥ 5mm and radiographic evidence of identical osseous defects in the mandibular molar region bilaterally were included in this prospective study. A gel based drug delivery system of Alendronate was formulated. Following surgical flap debridement, 0.1 ml alendronate gel and 0.1 ml placebo gel was placed at the experimental and control sites respectively. Clinical and radiographic parameters were recorded at baseline, three months and six months post surgery.
Results:
Alendronate was more effective in improving clinical and radiographic parameters compared to placebo.
Interpretation and Conclusion:
Alendronate is effective in the management of periodontitis associated bone loss. Gel based local delivery of the drug addresses the critical concern of exposing the patient to adverse effects of systemic administration.

DOI
:10.4103/0972-124X.65427
PMID
:20922072
Background:
Neutrophils constitute the main phagocytic cell system in mammalian host defense against an infecting agent. Abnormalities in leukocyte number and function are associated with increased susceptibility to periodontal diseases. The purpose of this study is to evaluate the
in vitro
phagocytic properties of crevicular and peripheral blood neutrophils in healthy and periodontitis subjects.
Patients and Methods:
A total of 30 subjects, that is, 10 patients in each of the following three groups: healthy controls, chronic periodontitis (CP), and localized aggressive periodontitis (LAP), were included in the study. The neutrophils were isolated from the peripheral blood and gingival crevice and tested for phagocytosis of
Candida albicans
. The percentage of leukocytes with ingested
C. albicans
was determined by light microscopy.
Results:
A significant reduction in the phagocytic activity of crevicular fluid polymorphonuclear neutrophils (CF-PMN) of LAP subjects (mean: 54.3±7)(
P
<0.001) was observed, compared to healthy controls (mean: 74.2±9) and chronic periodontitis subjects (mean: 69±9)(
P
=0.352). The mean percentage of peripheral blood polymorphonuclear neutrophils (PMNs) with phagocytosis of opsonized
C. albicans
in LAP patients was significantly reduced (mean: 74.9±5)(
P
<0.0068) compared to the phagocytic activity of neutrophils from controls (mean:82.1±3) and chronic periodontitis subjects (mean: 82.0±5)(
P
=0.970). There was no significant reduction in the phagocytic activity of CF PMNs (mean: 69±9) (
P
=0.35) and peripheral blood PMNs (mean: 82.5)(
P
=0.97) in the chronic periodontitis group when compared to the control group.
Conclusion:
The phagocytic activity of both crevicular and peripheral neutrophils in subjects with periodontitis is altered, increasing the susceptibility to periodontitis. Thus individual susceptibility may be an additional and important modifying factor in the pathogenesis of periodontal disease.

Effect of green tea catechin, a local drug delivery system as an adjunct to scaling and root planing in chronic periodontitis patients: A clinicomicrobiological study
Praveen Kudva, Syeda Tawkhira Tabasum, Nirmal Kanwar Shekhawat
January-March 2011, 15(1):39-45
DOI
:10.4103/0972-124X.82269
PMID
:21772720
Background:
Evaluate the adjunctive use of locally delivered green tea catechin with scaling and root planing, as compared to scaling and root planing alone in the management of chronic periodontitis.
Materials and Methods:
Fourteen patients with two sites in the contralateral quadrants with probing pocket depth of 5−8mm were selected. Each of the sites was assessed for the plaque index, gingival index, and probing pocket depth at baseline and 21 days and for microbiological analysis at baseline, 1 week and 21 days. Test sites received scaling and root planing along with green tea catechin strips and control sites received scaling and root planning alone.
Results:
The result showed intercomparison of the plaque index and gingival index for test and control groups at 21 days was not significant with
P
>0.05, whereas the probing depth at 21 days was significant with
P
<0.001. Intercomparison between microbial results demonstrated a considerable reduction of occurrence of Aggregatibacter actinomycetemcomitans, Prevotella intermedia, Fusobacterium species and Capnocytophaga in test.
Conclusion:
Green tea catechin local delivery along with scaling and root planing is more effective than scaling and root planing alone.

Propolis mouthwash: A new beginning
Vidya Dodwad, Bhavna Jha Kukreja
April-June 2011, 15(2):121-125
DOI
:10.4103/0972-124X.84379
PMID
:21976834
Background:
This study was carried out to investigate the effectiveness of a propolis-containing mouthrinse in inhibition of plaque formation and improvement of gingival health.
Materials and Methods:
Thirty subjects were selected and randomly assigned into three groups of ten subjects each, which received a propolis-containing mouthrinse, or a negative control (Saline) or a positive control (Chlorhexidine 0.2%). Plaque index and gingival index were assessed at baseline and at a five-day interval.
Results:
Chlorhexidine mouthwash was found to be better than propolis and saline in inhibiting plaque formation. Propolis was found to be only marginally better than chlorhexidine in improving gingival scores.
Conclusion
: The present study suggests that propolis might be used as a natural mouthwash, an alternative to chemical mouthwashes, e.g., chlorhexidine. Further, long term trials are required for more accurate data and any conclusive evidence.

Effect of local drug delivery in chronic periodontitis patients: A meta-analysis

Periodontal diseases are multi-factorial in etiology, and bacteria are one among these etiologic agents. Thus, an essential component of therapy is to eliminate or control these pathogens. This has been traditionally accomplished through mechanical means (scaling and root planing (SRP)), which is time-consuming, difficult, and, sometimes, ineffective. From about the past 30 years, locally delivered, anti-infective pharmacological agents, most recently employing sustained-release vehicles, have been introduced to achieve this goal. This systematic review is an effort to determine the efficacy of the currently available anti-infective agents, with and without concurrent SRP, in controlling chronic periodontitis. Four studies were included, which were all randomized controlled trials, incorporating a total patient population of 80, with 97 control sites and 111 test sites. A meta-analysis completed on these four studies including SRP and local sustained-release agents compared with SRP alone indicated significant adjunctive probing depth (PD) reduction for 10% Doxycycline hycylate (ATRIDOX), minocycline hydrochloride (ARESTIN), tetracycline hydrochloride (PERIODONTAL PLUS AB), and chlorhexidine gluconate (PERIOCHIP). Essentially, all studies reported substantial reductions in gingival inflammation, plaque scores, and bleeding indices, which were similar in both the control and the experimental groups. Use of antimicrobial sustained-release systems as an adjunct to SRP does not result in significant patient-centered adverse events. Local drug delivery combined with SRP appears to provide additional benefits in PD reduction compared with SRP alone.

Histoplasmosis is a systemic fungal disease that takes various clinical forms, among which oral lesions are rare. The disseminated form of the disease that usually occurs in association with Human Immunodeficiency Virus (HIV) is one of the AIDS-defining diseases. Isolated oral histoplasmosis, without systemic involvement, with underlying immunosuppression due to AIDS is very rare. We report one such case of isolated oral histoplasmosis in a HIV-infected patient.

Periodontal diseases produce physical and chemical alterations in the root cementum. Various topical applications as root conditioning agents have been recommended as an adjunct to mechanical root surface debridement to remove smear layer, endotoxins and to expose collagen fibers on dentin surface. The objectives were to compare dentin surface changes following applications of tetracyclines and citric acid to the instrumented root surface of periodontally involved human teeth under scanning electron microscope. The study group comprised of 80 dentin samples, which were prepared from periodontally-compromised teeth, planned for extraction. Diseased surfaces were root planed. The teeth were sectioned and solutions of tetracycline HCl, minocycline, doxycycline and citric acid were applied to the surfaces with cotton pellets for 5minutes.The root surface samples were then examined by scanning electron microscope. Removal of smear layer in all the four groups was near total except a few areas. All four groups showed slight difference in mean number of total dentinal tubules. Minocycline and doxycycline showed no significant difference. The proportion of patent dentinal tubules was (74%) in tetracycline HCl group compared to minocycline (48.3%), doxycycline 42%), citric acid (52%), showing the differences statistically significant. Tetracycline group showed higher number of patent tubules when compared to minocycline, doxycycline and the difference was statistically significant. Results of this study suggest that tetracycline is the best current tetracycline form for root surface conditioning as measured by its ability to affect both dentin smear layer removal and tubule exposure.

Three-dimensional imaging in periodontal diagnosis - Utilization of cone beam computed tomography

In the field of periodontology and implantology, assessment of the condition of teeth and surrounding alveolar bone depends largely on two-dimensional imaging modalities such as conventional and digital radiography. Though these modalities are very useful and have less radiation exposure, they still cannot determine a three-dimensional (3D) architecture of osseous defects. Hence, an imaging modality which would give an undistorted 3D vision of a tooth and surrounding structures is essential to improve the diagnostic potential. Cone-beam computed tomography (CBCT) provides 3D images that facilitate the transition of dental imaging from initial diagnosis to image guidance throughout the treatment phase. This technology offers increased precision, lower doses, and lower costs when compared with medical fan-beam CT. This review discusses all the finer details of CBCT which not only reveals 3D architecture of the periodontium but also helps to reconstruct it.
