Abstract：Objective To observe the dentition defect occurring in different teeth, and to analyze dentition defect susceptibility of teeth. Methods Oral health status of 652 elderly people in Tangshan city was collected.The missing rate of different teeth was analyzed. Results Eight hundred seventy-six teeth( 19.19% ) missed in the left maxillary and 955 teeth (20.92%) missed in the right. Eight hundred nineteen teeth ( 17.94% ) missed in the left mandible and 891 teeth (19.52%) missed in the right. The deletion rate of ipsilateral different teeth had significant differences (all P ＜ 0. 01 ). One thousand eight hundred and thirty-one teeth(20.05% ) missed in the maxillary and 1710 teeth ( 18.73% ) missed in the mandible. The missing rate of maxillary was highest in first molar, followed by second molar, second premolar, first premolars, central incisor, lateral incisors and canines. The missing rate of mandible was highest in first molar, followed by second molar,second premolar, central incisor, first premolars, lateral incisors and canines. Conclusions The situation of dentition defect has significant symmetry. There is different susceptibility of dentition defect among different dental positions.
