ABSTRACT


Aim

The purpose of this study was to assess and compare the rate of sealant retention and microleakage after placement
on etched enamel with and without prior deproteinisation.

Methods

Study design: 75 freshly extracted third
molars were randomly assigned to either of two pit and fissure treatment methods. Samples from both groups were etched with
37 phosphoric acid gel for 15 seconds, followed by placement of a sealant, and then subjected to thermocycling for evaluation
of sealant retention. After that, specimens were immersed in rhodamine B, sectioned longitudinally, and examined under a confocal
laser scanning microscope for assessment of microleakage. Collected data were statistically analysed using chi-square and Fisher
exact tests with an level of 0.05.

Results

The rate of sealant retention was similar between the two study groups (P = 0.073),
but the rate of sealant microleakage was significantly lower in the enamel deproteinisation group (P < 0.001) than in the control group.

Conclusion

Based on these findings, we recommend the deproteinisation method prior to enamel acid etching to obtain better
clinical results with sealants.
