Comparative study of microleakage of a pit and fissure sealant placed after preparation by Er:YAG laser in permanent molars.
J Dent Child (Chic) 2003 May-Aug; 70(2):134-8JD

Abstract

PURPOSE

The aim of this study was to assess the microleakage of a pit and fissure sealant on enamel treated with a laser, with and without etching.

METHODS

Sixty non-carious extracted molars were randomly assigned to 2 groups. For both groups, in the mesial halves, the fissures were widened mechanically with a bur and etched for 15 seconds. In group 1, the distal half was prepared with a laser alone; in group 2, a laser was followed by etching. Then the sealant was applied on all teeth.

RESULTS

Laser alone showed the highest number of specimens with microleakage (63%) (P < .02) and the highest mean of microleakage (0.76 mm vs 0.12 mm, 0.17 mm, and 0.18 mm; P < .01).

CONCLUSIONS

No significant difference was noted between the 2 types of enamel preparation when etching was performed. Laser irradiation did not eliminate the need for etching the enamel surface before applying the sealant.
