RESUMO
The aim of this investigation was to study the effect of dentin depth and patient's age on the shear bond strength of one dentin adhesive [ART Bond], using an Instron Universal testing machine at a cross-head speed of 0.5 mm/min. Forty human molar teeth were used and were divided into two main groups, twenty each representing two age groups of patients, i.e., between 20 to 30 years and between 30-40 years of age. Every group was further subdivided into two subgroups of different dentin depths, i.e., superficial and deep. Results were recorded in Kg/Cm[2] and converted into MPa units, then tabulated and statistically analyzed. A Duncan's range statistic test at P
