Background:The microbial fl orae in adult periodontitis lesions are comprised of anaerobic rods with Porphyromonas gingivalis as one of the major components (Slots 1976; Slots 1979; and Tanner et al., 1979). P. gingivalis is a black-pigmented gram-negative anaerobic rod and a secondary colonizer of dental plaque requiring antecedent organisms. The presence of this organism either alone or as a mixed infection with other bacteria and with the absence of benefi cial species appears to be essential for disease activity. It is a predominant member of the subgingival microbiota in disease. It possesses and "excretes" numerous potentially toxic virulence factors. Aim of this study is to perform a systematic review of studies on P. gingivalis and its virulence factors with a special focus on its vaccine. Materials and Methods: An electronic and manual search based on agreed search phrases between the primary investigator and a secondary investigator was performed for the literature review till January 2014. The articles that were identifi ed by this systematic review (total of 190) were analyzed in detail, which included the study of inference and conclusion. Conclusions: Within the limits of this systematic review, it can be concluded that P. gingivalis induce immune infl ammatory response in periodontitis subjects. Therapeutic vaccines need to be developed and studied for their effi cacy in controlling periodontitis.

Background: Oral diseases are a major public health concern owing to their high prevalence and their effects on the individual's quality of life. Although many studies have been carried out from time to time to assess the knowledge and behaviour of people about oral health, there is still a lack of awareness and practice regarding the same. Aim: To assess oral hygiene awareness among patients visiting the Department of Periodontology at Government Dental College and Hospital, Jamnagar Materials & Methods:Across-sectional study was carried out among 500 patients visiting the Department of Periodontology at Government Dental College and Hospital, Jamnagar. Subjects were selected using a convenient sampling technique and were asked to ll a self-constructed questionnaire consisting questions regarding awareness and practices related to oral hygiene. Responses from the patients were evaluated in terms of numbers and percentages. Results: The results of the study showed an acute lack of oral hygiene awareness and limited knowledge of oral hygiene practices as well as effect of poor oral hygiene on systemic health. Conclusion: There is an urgent need for comprehensive educational programs to promote good oral hygiene and impart education about correct oral hygiene practices

Introduction: Periodontal diseases have a multifactorial etiology but some risk factors like genetics also can be responsible for disease progression. These dermal ridge patterns remain unchanged throughout the life .They are unique for each individual, it can be considered as a benecial tool for prediction of any congenital, intrauterine anomalies or other diseases which inuenced by genetic alterations .Genetic determinants that exist could be suggestive of specic dermatoglyphic patterns for periodontitis. To analyze the palmar dermatoglyphic Aim: patterns of healthy and chronic periodontitis patients and to nd any correlation between them. A total of 150 patients were Materials & Methods: equally divided into two groups comprising 75 patients in each group as follows: Group I-periodontally healthy, Group II-chronic periodontitis. The ngerprint patterns of all the patients in each group were obtained and analyzed with the help of magnifying glass. There was a Results: signicantly higher percentage of whorls in Group II compared to Group I. There was no signicant difference between both the groups for arch patterns. There can be a signicant correlation between the dermatoglyphic pa Conclusion: ttern of healthy and the chronic periodontitis as whorl nger pattern predominates in chronic periodontitis patients. So it can be serve as predictor in identifying the risk group individuals of chronic periodontitis.

Background & Objective: An association between oral conditions such as periodontal diseases and systemic conditions is noted. As such, periodontal disease is associated with an increased risk of systemic illnesses such as cardiovascular disease, diabetes, adverse pregnancy outcome and stroke. Keeping this in view, the present survey was designed to evaluate the acquaintance, orientation and behaviour of general medical practitioners; concerning the effects of periodontal disease on systemic health. Materials and Methods: A typed questionnaire carrying sets of questions was distributed among general dental practitioners and non-dental practitioners of Gujarat government and private set ups. Questionnaire was developed to assess the acquaintance, orientation and behaviour of doctors towards periodontal disease. Results: Dental practitioners have knowledge regarding the inter-relationship of periodontal disease and systemic conditions. And most of the non-dental practitioners have knowledge regarding the inter-relationship of periodontal disease and diabetes mellitus. However, majority of them do not know about the potential effect of periodontal disease on other organ systems. Conclusion: General medical practitioners have inadequate knowledge regarding inter-relationship. Hence, oral health related training should be an integral part of the medical curriculum
