Abstract
OBJECTIVE: To evaluate the efficacy of calcium sodium phosphosilicate bioactive glass (NovaMin) as a chair side desensitizing agent. MATERIALS AND METHODS: The study was conducted on 60 subjects divided into 3 groups of 20 each as follows. Group I (NovaMin application without scaling and root planing), Group II (NovaMin application after scaling and root planing) and Group III (control group). Sensitivity was assessed using air blast and cold water stimulus at baseline, immediately after application, after half an hour and after 8d using Visual Analog Scale (VAS). RESULTS:Mean VAS (air blast stimulus) for group I was 5.9 at baseline, 3.4 immediately after application, 3.05 after half an hour, and 3.0 after 8 days. In group II VAS score were 6.2, 3.35, 2.9, 2.75 and group III 6.6, 7.0, 7.0, 7.0 respectively. For cold water stimulus in group I VAS score were 5.6, 3.35, 3.15, 3.1, group II VAS score 5.7, 3.35, 3.1, 2.85 and group III 5.8, 6.1, 6.05, 6.05 respectively. VAS scores in between group I and group III and group II and group III were statistically significant (<0.001) immediately after application, after half an hour and after 8days (ANOVA). CONCLUSION: Chair side application of calcium phosphosilicate bioactive glass can be a therapeutic adjunct to provide immediate relief for the patient with dentinal hypersensitivity.
