Objectives:
The purpose of this in-vitro
study was to evaluate the microleakage of a self-etch dentin adhesive system in
cavities prepared by a conventional dental bur and an Er,Cr:YSGG laser.
Materials
and Methods: Forty extracted
premolar teeth were selected randomly. Standardized Class V cavity preparations
were placed in the buccal and lingual surfaces using a bur and an Er,Cr:YSGG laser.
Eighty preparations were randomly assigned to 4 groups of 20 samples each and
restored as follows: (G1, Control group) Bur; (G2) Bur + Laser etch; (G3)
Er,Cr:YSGG laser; (G4) Er,Cr:YSGG laser + Laser etch. The cavities were
restored with a self-etch adhesive system (GC, Unifil Bond) and composite resin
(GC, Gradia). The preparations were sectioned buccolingually into three parts
and scored for microleakage using a light stereoscope. The data were analyzed with
Mann-Whitney U test, and Chi-squared test was used for comparisons across
groups.
Results: In all
groups, there was higher microleakage in the gingival margin than in the occlusal
margin. In the control group (G1), the lowest microleakage values were obtained
in all the cavities. In comparison among the groups, statistically significant
microleakage values were obtained in the occlusal margins. Significantly high
microleakage was observed in G4 in comparison to G1 and G3 (p = 0.001, p =
0.003).
Conclusions: Preparation and etching by using an Er,Cr:YSGG
laser does not decrease microleakage, but this may also be due to the
properties of the self-etch adhesive. Further clinical research and long-term
follow-ups are needed to analyze the findings in more detail.
