ABSTRACT
OBJECTIVES:
The purpose of this study was to compare the microshear bond strength (microSBS) and bonding interfaces of two-step total-etching and self-etching adhesive systems to three etch types of dentin either the acid etched, laser etched or laser and acid etched. MATERIALS ANDMETHODS:
The occlusal dentinal surfaces of thirty human molars were used. They were divided into six groups group 1, 37% H3PO4 + Single Bond 2 (3M ESPE); group 2, ErYAG laser (KEY Laser 3, KaVo) + Single Bond 2; group 3, ErYAG laser + 37% H3PO4 + Single Bond 2; group 4, Clearfil SE Primer + Bond (Kuraray); group 5, ErYAG laser + Clearfil SE Bond; group 6, ErYAG laser + Clearfil SE Primer + Bond. The samples were subjected to microSBS testing 24 hr after bonding. Also scanning microscopic evaluations were made on the resin-dentin interfaces of six specimens.RESULTS:
The microSBS of group 2 was significantly lower than that of groups 1 and 3 in Single Bond 2 (p < 0.05). There were significant differences among the uSBS of groups 4, 5, and 6 in Clearfil SE Bond (p < 0.05). Very short and slender resin tags were observed in groups 2 and 5. Long and slender resin tags and lateral branches of tags were observed in groups 3 and 6.CONCLUSIONS:
Treatment of dentin surface using phosphoric acid or self-etching primer improved the adhesion of ErYAG lased dentin.
