This study aimed to clinically evaluate the 3-years clinical performance of glass ionomer and resin based adhesive systems in Class V restorations.

The formulated null hypothesis was that there is no significant difference in the clinical performances between glass ionomer and resin based adhesive systems in Class V restorations for 3-years.

The research question was as follows: Do glass ionomer adhesives in class V restorations present better clinical performances than resin based adhesive systems according to the modified United States Public Health Service (modified-USPHS) criteria?
