AIM: The purpose of this study was to evaluate the effectiveness of three
desensitizing agents on dentinal tubule obliteration and their durability in use
on the dentinal tubules. MATERIALS AND METHODS: Sixty specimens were obtained
from 30 extracted sound human maxillary first premolars. Each tooth was
mesiodistally sectioned to obtain 30 buccal and 30 lingual surfaces, and enamel
was removed in order to simulate hypersensitive dentin. Specimens were divided
into four groups with 15 specimens each. Group 1 samples were immersed in
artificial saliva, Group 2 samples were coated with Vivasens, Group 3 samples
were coated with VOCO Admira Protect, and Group 4 samples were coated with Neo
Active Apatite suspension. These specimens were examined under scanning electron
microscope (SEM) to find out the occluding ability of the respective products.
The specimens were brushed to find out their durability for 1 week and 1 month
and were examined under SEM. STATISTICAL ANALYSIS: The results were statistically
analyzed by analysis of variance (ANOVA) and Tukey's test. RESULTS: Group 1
differed significantly from the Vivasens, Admira, and Neo Active Apatite groups
at 5% level of significance (P < 0.05). The Vivasens group differed significantly
from the Admira and Neo Active Apatite groups at 5% level of significance (P <
0.05). CONCLUSION: The Ormocer-based Admira Protect showed the best results.
