ABSTRACT
@#Introduction: Vital bleaching of teeth is associated with mineral loss and surface roughness leading to hypersensitivity. Aesthetic restorations are recommended after one week. Search is on for a suitable remineralizing material, which helps in instant adhesive bonding. Hence objective of the study is to evaluate the remineralizing efficacy of two concentrations of Silica doped Nanohydroxyapatite on bleached enamel. Methods: Enamel surfaces of 30 extracted human central incisors were divided into Part A: Unbleached enamel, Part B: Bleached enamel, Part C: Remineralized enamel. The samples were randomly divided into, Group 1: MI Paste Plus (Recaldent, USA), Group 2 and 3 for application of Dentin bonding agents (Tetric- n-bond, Ivoclar, Vivadent) mixed 0.2% and 0.8% Silica doped Nanohydroxyapatite (Sigma Aldrich, Bangalore, India). Post bleaching remineralizing agents were applied on part C. Surface roughness was evaluated with contact stylus profilometer and mineral content was evaluated with Energy dispersive X-Ray spectroscopy for three parts. Data were analysed using ANOVA and Post Hoc Tukey test with p ≤ 0.05. Results: Surface roughness values (Ra) were increased, and mineral loss (Ca:P) was observed after bleaching. After application of remineralizing agents, surface roughness was decreased with no significant value (p > 0.05) and a significant increase in mineral content of all three groups with a p < 0.05 was observed. Conclusion: Application of dentin bonding agent mixed with Silica doped Nanohydroxyapatite decreased surface roughness and improved remineralization of bleached enamel.
ABSTRACT
AIM: The aim of this study was to assess the effectiveness of two herbal mouthwashes in comparison with Chlorhexidine mouthwash on gingivitis. MATERIALS AND METHODS: This is a triple-blind randomized controlled clinical trial, where in 60 patients were randomly allocated into three study groups: Triphala mouthwash (Group A), Aloe vera mouthwash (Group B), and Chlorhexidine mouthwash (Group C). All groups were treated with scaling and asked to rinse with respective mouthwashes twice daily for 1 month. Clinical parameters such as plaque index (PI), gingival index (GI), and bleeding index (BI) were recorded at baseline, 15 days, and 30 days, respectively. RESULTS: Our results suggested that Triphala group effectively demonstrated a higher reduction in GI and BI index scores compared to A. vera group (P ≤ 0.005) and the effect is equivocal to the reduction seen with Chlorhexidine group. However, no statistically significant difference was observed between the mouthwashes in reduction of PI scores (P > 0.005). CONCLUSION: The results of our study evidenced Triphala to be superior in the reduction of plaque, gingival inflammation, and bleeding compared to that of A. vera. However, the results of our study also indicated that Triphala was as effective as chlorhexidine mouthwash in its ability in reducing plaque accumulation, gingival inflammation, and bleeding. Furthermore, Triphala is relatively free of side effects compared to that of chlorhexidine.
