Research paper thumbnail of Effects of Non-surgical Periodontal Therapy on Saliva and Gingival Crevicular Fluid Levels of Chemerin in Periodontitis Subjects With and Without Type 2 Diabetes Mellitus

Chemerin, an adipose tissue-specific adipokine plays a significant role in adipocyte initiation and differentiation that directly influences glucose metabolism, lipid metabolism, and inflammatory mediators. Non-surgical periodontal therapy (NSPT) for patients with periodontitis and diabetes mellitus improves the periodontal condition and regulates glycemic level. Aims and objectives To assess the impact of chemerin on periodontal disease and diabetes mellitus pathogenesis and to analyze the impact of NSPT on saliva and gingival crevicular fluid (GCF) chemerin levels in patients with periodontitis with and without type 2 diabetes mellitus (T2DM). Materials and methods A total of 60 patients were divided into four groups: Group I: Systemically and periodontally healthy subjects (n=15), Group II: Systemically healthy subjects with periodontitis (n=15), Group III: Subjects with periodontitis and T2DM (n=15), Group IV: Periodontally healthy subjects with T2DM (n=15). Indices and parameters like plaque index (PI), gingival index (GI), periodontal probing depth (PPD), and clinical attachment level (CAL) were assessed at baseline in all four groups and six weeks after NSPT in Group II and Group III. A glycated hemoglobin (HbA1c) test was taken to assess the patient's blood glucose level. Fasting blood sugar (FBS) level was taken at baseline in all the groups and six weeks after NSPT in Group II and Group III subjects. Saliva and GCF chemerin levels were assessed at baseline in all four groups and six weeks after NSPT in Group II and Group III subjects. Results A statistically significant difference was observed in comparing chemerin levels at baseline with all four groups (p < 0.001). After NSPT, there was a reduction in clinical parameters, FBS, and chemerin levels in Group II and Group III. A positive correlation was observed between salivary chemerin and FBS in Group II, GCF chemerin, PI, and FBS in Group II, and PPD and FBS in Group III. A negative correlation was observed between salivary chemerin and all parameters in Group II and between salivary chemerin and GCF chemerin in Group III. Conclusion Based on the observed relationship between chemerin and the parameters, their utility as a dual biomarker for diagnosis and prognosis in periodontal disease seems promising. However, further studies with a larger sample size on the role of chemerin in health and various states of diseases are required to substantiate the result of the study.

In the recent years by the evolution of various oral hygiene aids accompanied by modified methods a great improvement in the oral health is noted. Tooth brushing and flossing are the most common practices to maintain a good oral health along with regular dental visits. Tooth brushing is the act of scrubbing teeth with the help of tooth brush and tooth paste. It is a very effectual measure to maintain good oral hygiene and to prevent dental caries as well as periodontal problems which either directly or indirectly affects systemic health of an individual. Objective: The present random sample survey was conducted to assess the knowledge of using oral aids among dentulous patients. Methodology: A questionnaire consisting of 12 questions pertaining to brushing and methods or technique of using tooth brushes was framed. 150 randomly selected samples were chosen and were evaluated about the knowledge of usin...

Research paper thumbnail of Virtual autopsy: An imaging technological integration in forensic odontology

This is despite the availability of the technological advances in today's clinical settings. This review discusses the feasibility of integration of virtual autopsy in forensic odontology practice in an Indian setting. Using high-tech radiological approaches, virtual autopsy provides an efficient and more accurate view on cases such as thanatological investigations, carbonized and putrefied body identifications, mass disaster cases, age estimation, anthropological examinations, and skin lesion analyses. In certain cases, the postmortem photographic and radiological examination becomes essential as the access to the oral cavity is hindered. These become feasible with the advent of availability of antemortem radiological digital formats stored in hospital settings, with the improved collection of data compared to the traditional techniques. However, we do not have any state and national level protocols and laboratories to augment the capabilities further. Virtual autopsy is likely to replace conventional autopsies in the future. Thus the century-old investigation system in our country can be upgraded by the utilization of this Modern Technology. This review advocates a multidisciplinary research and advocacy to develop improved tools and protocols for virtual autopsy and to stress the role of forensic odontologists in an Indian setting.
