ABSTRACT
PURPOSE:
To evaluate the efficacy of conventional acid etching alone (acid etching) and ErYAG laser combined with acid etching (laser + acid etching) on fissure sealant (FS) retention of first permanent molars (FPMs) after 18 months. MATERIALS ANDMETHODS:
Using a split-mouth design in 51 children, a total of 204 FPMs were sealed with acid etching alone or laser plus acid etching (laser+acid). The retention of sealants and occurrence of caries were evaluated at 3, 6, 12, and 18 months. Statistical analysis was performed using Pearson's chi-squared tests.RESULTS:
The retention rate for FS in the laser+acid group was significantly higher than that of the acid-etch group at 12 (pâ¯=â¯0.0161) and 18 (pâ¯=â¯0.0227) months. Six FSs in the acid group and five FSs in the laser+acid group were completely lost after 18 months. The incidence of caries in the acid-etch group was 22% (nâ¯=â¯18) vs 10% (nâ¯=â¯8) in the laser+acid group at 18 months. The difference in caries development between the groups was not significant (pâ¯>â¯0.05).CONCLUSIONS:
As enamel pretreatment, ErYAG laser combined with acid etching significantly improves FS retention over conventional acid etching alone.
