Background: Remnants of dental calculus, contaminated cementum, and subgingival plaque act  as  a  physical  barrier  between  periodontal  tissues  and  root  surfaces,  which  inhibits  the formation of new attachment. Treatment of denuded root surface using various chemicals and antimicrobial agents with scaling and root planing helps in active periodontal regeneration. Aim: The aim of this study was to evaluate and compare the demineralizing effects of Triphala and 1% Tetracycline HCl gel on root conditioning using a Scanning Electron Microscope. Settings and  design:  A  total  of  50  hemi-sectioned  root  samples  were  obtained  from  25 extracted,  and  root  planed  samples.  These  were  divided  into  two  groups,  Group  1:  1% Tetracycline HCl gel and Group 2: Triphala. Materials and method: The two root conditioning agents were applied with cotton pellets on the sectioned roots. The samples were then examined under the scanning electron microscope. Statistical analysis used: Data obtained was compiled on a MS Office Excel Sheet. Inter group comparison was done using Mann Whitney U test. Comparison of frequencies of categories of variables with groups was done using Chi Square Test. Results: The root conditioning agents used in this study were found to be equally effective in removing the smear layer. 

Purpose: Dentinal hypersensitivity is a common clinical condition associated with exposed dentinal surfaces. Dentinal tubules can be entirely blocked after irradiation by 980-nm diode laser, with no significant morphological alterations after radiation. The use of toothpastes containing Potassium Nitrate and Calcium Hydroxyapatite reduces dentinal hypersensitivity. The main purpose of this study was to evaluate and compare the efficacy of Diode Laser and two Desensitizing Toothpastes for Dentinal Tubular Occlusion by Scanning Electron Microscopy (SEM). Methods: Twelve extracted premolars were divided into two halves each obtaining twenty-four dentin discs. Specimens were etched with 17% phosphoric acid to expose the tubules and were divided into four groups: i.e., Group A: Application of Diode Laser, Group B: Application of SHY-XT toothpaste, Group C: Application of Biomed toothpaste and Group D: Application of Distilled water. After treatment, quantitative analysis of occluded dentinal tubules was done by SEM analysis. Results: The mean values of total dentinal tubular occlusion in Groups A, B, C and D were 0.42, 0.86, 2.14, 4.07 respectively which was statistically significant (p<0.001*). Diode laser (Group A) yielded a significant occlusion of the dentinal tubules when compared to the two desensitizing toothpastes (Groups B and C).

Aim: To evaluate the clinical efficacy of subgingivally delivered SMV and Placebo gel and compare in the treatment of stage II periodontitis when used as an adjunct to SRP and their antimicrobial effect on the Porphyromonas gingivalis bacteria. Materials & Methods: In a split mouth study design, 10 systemically healthy patients with stage II periodontitis were included in this study based on the inclusion and exclusion criteria. Two sites with deepest pockets were selected. Plaque samples were collected from these pockets at baseline followed by full mouth scaling and root planning, In Group I 1,2% SMV gel and in Group II Placebo gel was placed in the subgingival pockets. Microbiological analysis for Colony Forming Units of P.g was done at baseline after 3 months, Clinical parameters (GI, PI, PD, CAL, mSBI) were evaluated at baseline (before SRP), 1 month and 3 months. Result: Both the groups showed significant reduction in GI, PI, PD, CAL, mSBI and CFU of Pg but Group I showed more significant reduction than Group II.
