Pathological investigation of caries and occlusal pulpar exposure in donkey cheek teeth using computerised axial tomography with histological and ultrastructural examinations.

摘要: Post-mortem examination of 16 donkey cheek teeth (CT) with caries (both peripheral and infundibular) pulpar exposure were performed using computerised axial tomography (CAT), histology scanning electron microscopy. CAT imaging was found to be useful assess the presence extent pulp in individual CT. Histology identified loss occlusal secondary dentine, showed necrosis exposure. Viable present more apically one exposed horn, its aspect sealed off from horn by a false stone. Scanning microscopy amelo-cemental junction possible route bacterial infection infundibular cemental caries. The basic pathogenesis dental donkeys appears very similar description other species.
