Objective: This multi‐arm, randomized, double‐blinded, controlled clinical trial was designed to evaluate the clinical efficacy of 0.5% green tea (GT), 0.2% chlorhexidine (CHX) and aloe vera (AV) mouthwash as compared to the control (CNT) group (scaling and polishing alone with no mouthwash) in the management of dental biofilm induced gingivitis among 18–40‐year‐old patients. Material and Methods: Sixty patients with generalized dental biofilm‐induced gingivitis were randomly allocated to four study groups (n = 15 each) for treatment, namely Group GT, Group CHX, Group AV and Group CNT after scaling and polishing were administered to all the patients. Plaque index (PI), gingival index (GI) and sulcular bleeding index (SBI) were recorded at baseline, 14th and 21st day. Results: PI, GI and SBI at various time intervals (baseline, 14th and 21st day) showed high statistically significant differences within the group (p < 0.01). Among these, the maximum percentage change was found in the CHX group followed by GT when evaluated from baseline to 21st day. The least percentage change was found in the AV group for PI and GI while the CNT group showed the least percentage change for sulcular index when evaluated from 14th to 21st day. Inter‐group results showed high statistically significant differences (p < 0.01) for PI and GI when evaluated between baseline to 14th day and baseline to 21st day. SBI also showed statistically significant differences (p < 0.05) when evaluated between baselines to 14th day and baseline to 21st day. Conclusion: Green tea mouthwash displayed a significant reduction in plaque index, gingival index and sulcular bleeding index. 0.5% green tea catechin has equivalent anti‐plaque efficacy as 0.2% chlorhexidine gluconate and can be considered a potent alternative to prevent and treat gingival diseases.

Aim: This in vitro study compared the effect of two commercially available silver diamine fluoride (SDF) products on dentinal tubule (DT) occlusion and dentin permeability., Methods: Sixty-six dentin discs (1.0 mm thick) were divided equally into six groups: acid-etched with no treatment (negative control-NC), etched and sealed with nail varnish (positive control-PC), non-etched and treated with Advantage Arrest (AA), non-etched and treated with Topamine (TP), etched and treated with AA, and etched and treated with TP. Eight specimens from each group were tested for permeability using the dye percolation method. The remaining three samples from each group were assessed for dentinal tubule occlusion, depth of SDF penetration, and elemental analysis using a scanning electron microscope coupled with an energy-dispersive X-ray (SEM/EDX) system. One-way ANOVA and Tukey's post hoc test were used to analyze the results., Results: TP exhibited lower (p < 0.05) dye percolation compared to AA. While both SDF materials showed a statistically similar (p > 0.05) penetration depth in the DT, none of them had the ability to completely occlude all the DTs. AA exhibited more silver and fluoride ion deposition on etched dentin than TP, and both materials showed a similar increase in the deposition of Ca and P compared to NC., Conclusions: Whereas the effectiveness of dentin tubule (DT) occlusion varies based on the material used, both tested SDF products exhibit the capability to seal dentinal tubules, decrease dentin permeability, and promote dentin remineralization. These findings suggest their potential advantage in managing dentin hypersensitivity., (© 2024 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)
