Objective
This study was conducted to evaluate and compare the laboratory effect of three different treatment modalities in dentinal tubules occlusion.
Materials and methods
Total of (27) teeth were enrolled in the study. Dentin discs prepared from teeth to apply desensitizing agents evaluated through occluding dentinal tubules by scanning electron microscope (SEM) examination. Discs were used in the study which were randomly divided into three groups (n=9) according to desensitizing agent (D) used while D1: Gluma adhesive, D2: Citrene varnish and D3: Charm varinsh. Each group was divided into three sub groups(n=3) according to storage time (T) where T1: 1 week, T2: 1 months and T3: 3 months.
Results
The results of this in-vitro study revealed that there was high significant difference (p ≤ 0.05) in percentage of dentinal tubules occlusion before and after treatment for all tested groups. Totally there was statistically significant difference (p ≤ 0.05) between the three groups as proven by Chi square test where Citrine varnish group was the highest followed by charm sense varnish group and the lowest was Gluma group in management of dentin hypersensitivity.
Conclusions:
Citrine varnish , Charm varnish and Gluma were effective in occluding dentinal tubules, with Citrine varnish being the most effective up to 3 months.
