拔牙２０００例统计分析太原市中心医院（０３０００９）白子珍，赵世英，姚红霞１９９１年我科抽样统计了２０００例拔牙患者，其中年龄最大者７９岁，最小者５岁，男性８３０人，女性１１７０人。其中，龋齿拔除率最高，占拔牙患者总数的４９．５％，滞留乳牙拔除者占拔牙总数的２０．５％居第二位，牙周病患者占拔牙人数的１０％，居第三位，多为老年人，比１９８４年北京市口腔医院报道的３７．２３％显著下降。阻生智齿占９．５％，多为反复引起冠周炎发作的青壮年人，男女无明显区别。其他原因引起的拔牙患者所占比例都小。本次统计中，女性拔牙者明显多于男性，从年龄上看，６０岁以上年龄组拔牙人次最多，其次为儿童，居第三位的青壮年人。本次统计数字提示我们，如何有效地预防和治疗龋病和牙周病仍是口腔医务工作者研究的主题。拔牙2000例统计分析@白子珍，赵世英，姚红霞$太原市中心医院
