The effect of home tooth bleaching on the bond between veneers composite resins and tooth enamel


Abstract in English

The research project sample consisted of 80 extracted central incisors obtained from the Oral and Maxillofacial Surgery Department as well as from private practices. These teeth were divided into two equal groups. The bonding agent ClearFil SE Bond was used in one group, whereas the OptiBond Solo Plus bonding agent was used in the other group. Each group was divided into four subgroups: (1) veneers performed without any bleaching, (2) veneers performed two weeks before bleaching, (3) veneers performed immediately following bleaching and (4) veneers performed two weeks after bleaching. veneers were made using a special template which allowed producing the same size of all the specimens used in this project. These veneers were placed on the vestibular surfaces of enamel of the extracted central incisors. The aim of the previous procedures was to study the effect of home teeth bleaching . Teeth were embedded in acrylic blocks created in metallic cylinders. The bonding strength was measured through . The results showed that there was a significant difference between the control subgroup and the second subgroup .
