Abstract
Objective: In order to observe and to compare several desensitization agents for dentinal tuble changes, Gluma, MS coat, 2% NaF, 10% SnF2 and SE bond were prepared.
Methods: 5 extracted 3rd Molar were prepared, and devided with 6 pieces per a tooth for 30 specimens, classified them with 6 groups as group 1 as without any treatment, group 2 as applied with Gluma for 3 times, group 3 as MS coat for 3 times, group 4 as 2% NaF for 4 times, group 5 as 10% SnF2 and group 6 as SE bond for a time. SEM observation was done for all specimens for 2 portions per a sample and the number and degree of the obstacle of dentinal tubules were calculated.
Results: It revealed the closing phenomina in all experimental group’s samples were more in numbers of the degree than in control group (p＜0.05), SE bond group was the most in closing the dentinal tubles and 10% SnF2 group was next, and MS coat, Gluma, and 2% NaF in sequence. There was no significant differences between in each experimental group by one way ANOVA test, with Tuckey or Sheffe test, otherwise there was a significant difference in statistical between in Gluma, 2% NaF and SE bond group by Dunkan test (p＜0.05).
Conclusion: All experimental group’s agents can be used for desensitization agents in hypersensitive dentin clinically, and SE bond was the most recommended for severe hyper sensitive dental patient.
