title: Dens evaginatus in the Thai. An evaluation of fifty-one cases.
abstract: Dens evaginatus in the Thai had not been described previously. The incidence of this abnormality was found to be 1.01 per cent. The male to female ratio was 1:1.83, a figure which is comparable to findings among the Chinese, since the two groups are closely related. The evagination was observed in fifty-one patients, with 133 premolars and one molar being affected. Thirty-six premolar showed periapical pathosis which was classified into clinical and radiographic features. The frequency of affection of the different premolars was described, together with the histologic appearances of the anomaly. Pathogenesis of dens evaginatus in the Thai seems to be uniform, determined by racial and genetic factors.
