Effect of Air Abrasion on Delayed Dentin Sealing Post-operative Sensitivity for Indirect Resin Composite Restorations

Abstract

BACKGROUND: There are several treatment options available to reduce the post-operative sensitivity (POS) of indirect resin composite restorations. AIM: This study was to evaluate the effect of air abrasion on delayed dentin sealing POS for indirect resin composite restorations. MATERIALS AND METHODS: Twenty-eight patients between the ages of 18 and 30 were enrolled and randomly assigned to one of two treatment groups, with 14 teeth (n = 14) in each group. Following the collection of baseline pre- operative data, the diagnosis of caries was made based on the clinical examination and radiographic examination, and all cavities were prepared. Group one (G1) prepared cavities were exposed to airborne particles before the selective etch technique was used without the use of cementation, and the selective etch technique was used. In the second group (G2), air abrasion during cementation. The visual analog scale was used to evaluate POS at baseline, 1 day after cavity preparation (T1), 1 week after indirect composite restoration cementation (T2), 3 months (T3), and 12 months (T4). STATISTICAL ANALYSIS USED: The one-sample Kolmogorov–Smirnov test was used to assess the normality of distribution parameters first, and then, for non-parametric distributions, the Kruskal–Wallis test was used to assess the interaction between different variables. The Mann–Whitney U-test was then used to compare the two groups. RESULTS: Despite air abrasion’s effect, there was no statistically significant change in scores between the G1 and G2 groups. POS was highest at T1, then T2, T3, and T4. Statistically, these differences were significant (p = 0.001). No statistically significant differences (p > 0.05) were found between T2, T3, and T4 with or without air abrasion. CONCLUSION: The delayed dentin sealing POS is unaffected by air abrasion during indirect resin restorations’ cementation.
