Abstract

Background : Dental stains are pigmented deposits that can be a predisposing factor for periodontal disease and caused aesthetic problems. Chromogens from foods and beverages such as coffee can adhere to the tooth surface trough pellicle and forming deposits called tooth extrinsic stains. Averrhoa bilimbi L contains oxalic acid which has potential ability to remove it trough oxidation mechanisms. The aim of this study was to investigate the effectiveness of Averrhoa bilimbi L extract solution on extrinsic tooth stain removal.Method : Tooth extrinsic stain models obtained by soaking the teeth in robusta coffee solution. Twenty-four post extraction premolar teeth with extrinsic stains were divided into 4 groups consisting of control group (immersion in artificial saliva), T1 group(immersion in Averrhoa bilimbi L extract solution 50%), T2 group (immersion in Averrhoa bilimbi L extract solution 75%) and T3 group (immersion in Averrhoa bilimbi L extract solution 100%) for 28 hours. Adobe Photoshop CC 2018 used to evaluate the difference color intensity (ΔE) in CieLAB system before and after the treatment.Result : Anova test showed there’s a significant difference within groups (p<0.05). Post Hoc Posttest showed there are  significant difference of difference color intensity (ΔE) between each group(p<0.05), with the highest average of it on T3 group then followed by T2 group , T1 group and control. Pearson correlation analysis showed there is a positive correlation between concentration and color intensity.Conclusion : Averrhoa bilimbi L. extract solution proven effective as extrinsic stain removal in vitro.

Abstract

Introduction: Direct pulp capping is a conservative treatment approach aimed at preserving pulp vitality following pulp exposure. Calcium hydroxide (Ca(OH)₂), mineral trioxide aggregate (MTA), and Biodentine are commonly used materials for this procedure. This systematic review aimed to compare the clinical, radiographic, and histological outcomes associated with these materials in direct pulp capping procedures. Method: A systematic literature search was conducted in PubMed, Scopus, ScienceDirect, and Google Scholar for studies published between 2015 and 2025. Only in vivo human clinical studies involving permanent teeth treated with Ca(OH)₂, MTA, or Biodentine were included. Study selection followed PRISMA guidelines. Data extraction focused on clinical success, pulp vitality, dentin bridge formation, and follow-up outcomes. Due to heterogeneity among the included studies, results were synthesized narratively. Results: Six clinical studies met the inclusion criteria and were included in the qualitative synthesis. Reported success rates for Ca(OH)₂ ranged from 13% to 37% in long-term follow-up. MTA demonstrated success rates exceeding 80% in studies with follow-up durations of at least 12 months. Biodentine showed comparable or slightly higher success rates than MTA in short- to medium-term observations. Radiographic and histological outcomes indicated more continuous dentin bridge formation in the MTA and Biodentine groups compared to Ca(OH)₂. Conclusion: Based on the available evidence, calcium silicate–based materials such as MTA and Biodentine appear to provide more favorable clinical and biological outcomes than calcium hydroxide for direct pulp capping procedures. Material selection should consider both biological performance and clinical handling characteristics to optimize treatment outcomes.
