Abstract
|
|
|
The purpose of this study was to compare the effect of desensitizing agents applied on
hypersensitive root surface following periodontal treatment. This study included 21
subjects(168 vital teeth).
To evaluate dentin sensitivity, three clinical tests(tactile, air stream, cold water) were tried and
three different densensitizing agents(MS coat, Elmex gel, Superseal) were individually applied.
After application, reassessment was done at 1 minute, 1 week, 1 month and 3 months.
The results were as follows :
1. The degree of dentin sensitivity was measured highly in the sequence of cold water, air
stream and tactile and significantly decreased in all four groups with lapse of
time(p<0.05).
2. There was no significant difference between all four groups in the tactile test with lapse
of time.
3. There was no significant difference between three experimental groups in the air streamtest with lapse of time. however, one minute later, it was measured highly in the
sequence of Superseal, MS coat and Elmex
4. There was no significant difference between three experimental groups in the cold water
test with lapse of time.
As a result of this study, all of three agents were significantly effective in reducing dentin
hypersensitivity and these agents could be positively employed to patients complaining of
dentin hypersensitivity following periodontal treatment
