BERWANGER, Carolina et al. Clinical retrospective evaluation of posterior composite resin restorations. Rev. Assoc. Paul. Cir. Dent. [online]. 2015, vol.69, n.4, pp. 355-362. ISSN 0004-5276.

The goal of this work was to perform a retrospective clinical evaluation of direct composite resin Class I and Class II restorations performed by students from UFRGS School of Dentistry.A total of 103 composite resin restorations (46 Class I and 57 Class II) were evaluated, following a modification of the USPHS and FDI methods. The evaluated restorations lifetime varied between 08 and 61 months.According to the FDI method, the main reason for the Class I restorations repair or replacement was because of recurrent caries (8.7%), followed by superficial brightness (8.6%). For class II restorations, the main failure reason was fracture and retention (29,8%), followed by dental integrity (24,5%). According to the USPHS method, superficial staining presented the highest failure rate for Class I (17,4%), followed by recurrent caries (13%). For Class II, superficial staining showed the highest failure rate (16%), followed by marginal adaptation (13,7%). Total failure rate for USPHS and FDI methods for Class I restorations was 32,6% e 20%, and for Class II restorations was 36,8% e 49,1%, respectively.It was concluded that the evaluated Class I restorations presented a positive clinical performance, with most criteria classified as excelent, good and satisfactory, in the evaluated period. A significant part of Class II restorations presented a insatisfatory or deficient performance in some evaluated criteria.
