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

BACKGROUND: Direct pulp capping (DPC) aims to preserve pulp vitality but requires agents that are both bioactive and biocompatible. Calcium hydroxide (CaOH2) is widely used, however its long-term success is limited, and it may cause adverse effects. Natural biomaterials such as chitosan and Aloe vera have shown potential, but their combined regenerative effects are still not well understood. This study was conducted to evaluate the efficacy of chitosan–Aloe vera composites in promoting stem cell activation, odontoblast differentiation, and reparative dentinogenesis in a rat model of reversible pulpitis.METHODS: Twenty-four Wistar rats with mechanically induced reversible pulpitis were divided into six groups: normal control, reversible pulpitis, CaOH2, and chitosan–Aloe vera pastes at 20%, 30%, and 40% (CA20, CA30, CA40). Pulp capping was performed following standardized pulp exposure. After 28 days, reparative dentin thickness and dentin bridge formation were assessed histologically, and STRO-1 and dentine sialophosphoprotein (DSPP) expression were analyzed immunohistochemically.RESULTS: Dentin bridge was observed in the CA40 group, presenting the thickest dentin formation (113.5±13.5 μm). STRO-1 and DSPP were significantly higher in all chitosan–Aloe vera combination groups compared with reversible pulpitis group (p<0.01), with DSPP in CA30 and CA40 also higher than CaOH2 group. Both biomarkers demonstrated a positive correlation, and reparative dentin thickness showed a strong positive correlation with DSPP level (r=0.786, p<0.001).CONCLUSION: Chitosan–Aloe vera combination showed encouraging biological activity in this 28-day preclinical model of reversible pulpitis. Although higher concentrations enhanced stem cell activation, odontoblast differentiation, and reparative dentin formation, these results should be interpreted cautiously due to the small sample size and study design limitations.KEYWORDS: pulp capping, STRO-1, DSPP, dentin bridge, CaOH2, natural biomaterial, endodontics
