摘要： 目的:探讨恒尖牙先天缺失的发生率及其临床特征,分析恒尖牙先天缺失的分布规律及临床特点。方法:收集恒尖牙先天缺失的患者,记录恒尖牙先天缺失发生的部位和数目。结果:恒尖牙先天缺失的发生率为0.51%(190/37086),男性110例多于女性80例,但性别间差异无统计学意义(P＞0.05);恒尖牙缺失1~2颗例数占98.42%(187/190);上颌恒尖牙缺失244颗明显多于下颌恒尖牙缺失33颗,差异有统计学意义(P＜0.01);左侧缺失133颗,略少于右侧的144颗,差异无统计学意义(P＞0.05)。结论:临床上偶然可以见到恒尖牙先天缺失。在例数上,恒尖牙先天缺失男性多于女性,但性别间无统计学差异,多为1~2颗恒尖牙缺失,上颌尖牙缺失多于下颌,但左右侧间分布无差异。

Abstract: Objective: To investigate the incidence and clinical characteristics of congenital permanent canines agenesis, and to analyze their distribution and clinical feature. Methods: Congenital permanent canines agenesis were collected, as well as the location and number of canines agenesis were recorded. Results: The prevalence of congenital permanent canines agenesis was 0.51% (190/37086). The number of boys (110) was more than that of girls (80), but there was no statistical difference (P＞0.05). One or two permanent canines agenesis accounted for 98.42%(187/190). The number of permanent canines agenesis in maxilla (244) was more than that in mandible (33), and the difference was statistically significant (P＜0.01). The number of teeth in the left jaw (133) was slightly less than that in the right (144), and the difference was not statistically significant (P＞0.05). Conclusion: The congenital permanent canine absence is occasionally happened in clinic. There was no difference between the genders. Most of the cases were 1-2 permanent canines absence, and the maxilla was more often happened than the mandible, however, no difference between the left and right sides.

Key words: congenital permanent canines agenesis, non-syndromic, panoramic radiograph, abnormality of tooth mumber
