A Comparative Evaluation of Fifth- and Seventh-Generation Dentin Bonding Agents in the Management of Dentin Hypersensitivity: A Randomized Controlled Clinical Trial
Soumya Pasala, Anusha Gummadi, Santhi GorleAbstract
Introduction:
Dentin hypersensitivity (DH), which cannot be linked to caries, pulpal pathology, or other flaws, is a brief, acute pain that arises from exposed dentinal surfaces when triggered by hot, cold, touch, air, or chemical agents. It affects people all over the world, with the highest incidence noted in people between the ages of 20 and 40. The condition usually results from mechanical abrasion, gingival recession, or enamel loss, which exposes dentinal tubules and allows stimulus transmission to the pulpal nerve ends, causing discomfort.
Objectives:
The objective of this study was to compare the desensitizing efficacy of a seventh-generation bonding agent (3M Single Bond Universal) and a fifth-generation bonding agent (Nano-Bond) in patients with DH.
Materials and Methods:
This was a single-center, double-blind, parallel-group, randomized clinical trial with 45 patients suffering from DH. Participants were divided into three groups: Single Bond Universal (3M ESPE), Nano Bond, and a control group. Discomfort Interval and Schiff Cold Air Sensitivity scores were recorded at baseline, immediately after treatment, 1 week, 1 month, and 3 months posttreatment to assess the effectiveness of the treatments.
Results:
The seventh-generation bonding agent group showed a reduction in Discomfort Interval Scale scores and Schiff Cold Air Sensitivity Scale when compared to the test group and control group.
Conclusion:
The study shows that the seventh-generation bonding agent is more effective in reducing DH over a 3-month period.
