ABSTRACT

Aim:

Recent reports indicate that deproteinization of acid-etched dentin surface can extend penetration depth of adhesive agents. The main goal of the present research was to investigate the deproteinization effect of NdYAG and diode 940 lasers on acid-etched dentin and microleakage grade in class V composite restorations.

Methods:

36 extracted human premolar teeth were selected to make standard buccal and lingual class V cavities. These samples were randomly split into three sub-groups 1.Control group, in which composite was applied for restoration after etch and bonding process without deproteinization; 2.NdYAG laser group, in which the teeth were deproteinized with NdYAG laser after etching and painting internal surfaces of cavities with Van Geison stain and then composite restorations applied just as control group; 3.Diode laser group, in which the process was similar to NdYAG laser group, but instead, diode 940 laser was irradiated. The teeth were bisected into two equal longitudinal buccal and lingual halves. Marginal microleakage of samples was scored by using a stereomicroscope. Kruskal- Wallis, Mann-Whitney U and Fisher's statistical tests were employed for analysis of the obtained data.

Results:

A significant reduction in marginal microleakage was observed for both groups treated with laser (NdYAG and diode 940)compared to control (p=0.001 & p=0.047). There was no significant difference in marginal microleakage between NdYAG laser and diode 940groups (P = 0.333).

Conclusion:

NdYAG and diode 940 laser deproteinization of acid-etched dentin decreased the marginal microleakage of in-vitro class V resin composite restorations
