Abstract :

Aims & objectives: The purpose of this study is to evaluate the surface topography of gutta percha (GP) after disinfecting with Sodium hypochlorite (5.25%), Silver nanoparticles (70 μg/ml) and chitosan nanoparticles (1.5 mg/ml) by atomic force microscopy (AFM). Materials and methods: Forty (40) Gutta percha cones were taken in this in vitro study. These samples were divided into four different groups such as: Group I – control group (untreated GP Points), Group II, III, and IV were treated with 5.25% Sodium hypochlorite (NaOCl), 70 μg/ml silver nanoparticles (AgNPs) and 1.5 mg/ml Chitosan nanoparticles (ChNPs) respectively. The surface topography analysis of the samples was performed using AFM. Statistical analysis: Root mean square (RMS) and surface roughness parameters were used to compare the structure of GP points with contact mode imaging. These values were tested by IBM SPSS-20.0 version statistical software using one-way ANOVA and Post-hoc (Tukey HSD) tests. They were considered statistically significant when P < 0.05. Results: The Root mean square (RMS) and surface roughness values are significantly higher for Sodium hypochlorite group (5.25% NaOCl) when compared with silver nanoparticles group (70 μg/ml AgNPs) and Chitosan nanoparticles group (1.5 mg/ ml ChNPs). Conclusion: This study has shown more surface topography deterioration of GP treated with NaOCl and lesser deterioration with AgNPs and ChNPs which affects postoperative prognosis.
