Interlinking Periodontitis and Type 2 Diabetes Mellitus by Assessment of Crevicular Visfatin Levels in Health and in Disease Before and After Initial Periodontal Therapy.

INTRODUCTION: Visfatin is a new adipocytokine associated with both chronic periodontitis and type 2 diabetes mellitus independently. AIM: We aimed to estimate and compare the changes in the levels of visfatin in the Gingival Crevicular Fluid (GCF) of healthy subjects and in subjects with periodontitis with or without controlled Type 2 Diabetes Mellitus (T2DM) after administration of non-surgical periodontal therapy. MATERIALS AND METHODS: Forty two subjects were equally divided into Group 1 (healthy), Group 2 (systemically healthy with chronic periodontitis), Group 3 (subjects with chronic periodontitis having controlled T2DM). Defined clinical parameters were recorded at baseline and at one month follow-up period. Visfatin was assessed using enzyme linked immunosorbent assay. One way ANOVA and Tukey's multiple post hoc procedures were used. Pearson's correlation coefficient was used for correlation. RESULTS: Significant increase in the visfatin levels was seen with the highest values observed in diabetes with periodontal disease. Visfatin responded to non-surgical periodontal therapy as observed by significant decrease in levels after one month but even at this period diabetics showed the highest levels. CONCLUSION: Visfatin levels are highest in individuals with both periodontal disease and diabetes even after periodontal therapy. Individuals with T2DM may be at higher risk of developing periodontal disease.

Comparison of a commercially available herbal and 0.2% chlorhexidine mouthrinse for prevention of oral malodor: A clinical trial.

OBJECTIVES: Despite the adverse effects of chlorhexidine (CHX) in the oral cavity, it is still the most commonly prescribed mouthrinse for halitosis control due to its excellent results. The purpose of this study was to compare the efficacy of a mouthrinse with herbal formulation for halitosis control with 0.2% CHX gluconate containing rinse and to simultaneously assess adverse effects caused by the herbal mouthrinse if any. MATERIALS AND METHODS: Ninety-six systemically healthy subjects with chronic generalized gingivitis were recruited in the study and divided into three groups receiving 0.2% CHX gluconate mouthrinse, herbal mouthrinse, or negative control, respectively as Group A, B, and C. The halimeter scores and organoleptic scores were recorded for each subject at baseline and after scaling. Others parameters recorded were plaque index and gingival index. All scores were reassessed on the 7(th) and 14(th) day, respectively. Statistical analysis was performed using Kruskal-Wallis ANOVA, Mann-Whitney U-test, and Wilcoxon matched pairs test. RESULTS: There was an overall reduction in the halimeter scores both in Group A and B subjects which were not statistically significant within the groups; this was in accordance with the decrease in the mean organoleptic scores. Reduction in Group C scores was the least and differed statistically from both Group A and B scores. CONCLUSIONS: The results indicate an equivalent reduction in breath odor by both the herbal mouthrinse and CHX. Furthermore, side effects were less, and patient compliance was more with the herbal mouthrinse, which can thus be prescribed more safely and with predictable outcomes for oral malodor.

A Comparative Evaluation of the Linear Dimensional Changes of Two Different Commercially Available Heat Cure Acrylic Resins during Three Different Cooling Regimens.

INTRODUCTION: Close mucosal adaptation of denture base to the underlying mucosa is of prime importance for denture stability. This however can be affected by various temperature changes which the denture base undergoes during processing and also to its material properties. AIM: The aim of the present study was to compare linear dimensional change of heat cure acrylic resin with three different cooling regimens on two different commercially available acrylic denture base resins. MATERIALS AND METHODS: Six groups of acrylic specimens with 10 samples each were prepared using either PYRAX or DPI acrylic resin, with a standard processing technique. Three different cooling methods were used for both the commercially available heat cure acrylic denture base resins. Linear dimensional changes were measured between three pre-determined points on the specimens of all the groups using a travelling microscope after removing the sample from the flask. One way ANOVA and unpaired t-test was used for statistical analysis. RESULTS: Linear dimensional change was more in quenching followed by air and water bath method of cooling respectively. Amongst the materials, linear dimensional changes were more in PYRAX than in DPI acrylic. CONCLUSION: Slow cooling by methods described should be advocated for better mucosal adaptation of the denture base.
