title: [Fracture resistance of human premolar with regard to morphological factors].
abstract: 173 extracted human upper and lower premolars were tested for their fracture resistance with regard to the morphological factors proximal vertical fluting and occlusal abrasion. Upper and lower premolars revealed a comparable fracture strength. The proximal groove did not influence the fracture resistance. Markedly abraded teeth showed a higher fracture strength than premolars without or with only a moderate occlusal abrasion. But these differences were not significant statistically. In total the morphological factors, which were considered in this study, should not influence the fracture resistance.
