Introduction

Oral diseases are exceedingly common in dogs and cats. In addition to pain and discomfort, systemic manifestations can exist as well. Therefore, the identification and treatment of these diseases are essential to overall health and welfare of our older pets.

Objectives

This study sought to assess the tensile bond strength of the resin composite restorations on healthy tooth enamel of dog incisors, "in vitro."

Aims

To perform this study 107 incisors with macroscopically healthy enamel were obtained.

Methods

Each tooth was etched with 37% orthophosphoric acid. A cube of composite resin was attached to each tooth using an adhesive resin and in each bucket a steel hook was inserted. The samples were divided in two groups: upper and lower incisors and they were submitted under tensile strength using a universal testing machine (Instron Tinius Olsen SH5K at the Institute of Materials Research and Testing) at a speed of 10 mm/min.

The results were analyzed using the test of variance and subsequently verified with Tukey's test with a degree of accuracy of 5%.

Conclusions

That there weren't significant differences (p > 0.05) between both groups under tensile strength, in vitro.
