Comparative evaluation of application of bioactive glass desensitizer and dentin bonding agent on prepared vital tooth in postoperative sensitivity at varying time period before cementation: An observational study.

Abstract

Aim: This study aimed to evaluate the clinical efficacy of bioactive glass as a desensitizer with dentin bonding agent in preventing the postvital tooth preparation sensitivity at three different time periods.

Settings and design: An Observational Study.

Materials and methods: 39 participants of age 25-30 years requiring vital tooth preparation were divided into Group A as control, distilled water as placebo; Group B test control, 7th generation dentin bonding agent; and Group C test, bioactive glass. Dentin hypersensitivity was evaluated on the day of preparation (T0), 7th day after preparation (T1), and 15th day (T2) at the final cementation procedure using the Schiff scale.

Statistical analysis used: IBM SPSS statistics software, One way analysis of variance (ANOVA), Post hoc Bonferroni.

Results: The descriptive statistics showed the mean and standard deviation at preapplication (T0) to be 2.23 ± 0.83, 2.53 ± 0.66, and 2.61 ± 0.65 for Group 1, Group 2, and Group 3, respectively, with no significant difference between the groups (P > 0.05). Intergroup analysis revealed there was a statistical difference between the 3 groups at T1 and T2, with post hoc Bonferroni depicting a lower mean for Group 3 of 1.53 ± 0.87 and 0.76 ± 1.09 at T1 and T2, respectively.

Conclusion: Bioactive glass has a significant reduction in the dentinal hypersensitivity on the vital prepared tooth compared to both negative control and dentin bonding agent.
