Avaliação clínica do uso do digluconato de clorexidina associado a um sistema adesivo autocondicionante em lesões cervicais não cariosas: estudo piloto

Abstract

This study evaluated the effect of the incorporation of chlorhexidine into primer of one self-etching adhesive system on the clinical performance of composite restorations placed in non-carious cervical lesions (NCCLs) at baseline and after 6 and 12 months. Sixty-five restorations were placed in 22 subjects being treated for NCCLs. The restorations were randomly placed in two groups: G1 (CSE): Clearfil SE Bond system applied following manufacturer’s instructions and G2 (CSE/CHX): as described in G1 but using the Clearfil Primer containing a concentration of 1% chlorhexidine digluconate. Filtek Z-250 composite resin was used as the restorative material for all restorations. Two clinicians evaluated the restorations blindly at baseline, 6 months and 12 months after restoration’s placement using a modified United States Public Health Service (USPHS) criteria. No statistically significant difference between the two groups was observed for all criteria evaluated.
