摘要
目的调查太原市儿童和青少年替牙期、恒牙期错畸形患病率、错类型构成比、各类错畸形的临床表现及其相关因素。方法以个别正常和Angle错分类为标准,设计统一的表格,对太原市5所中小学校7785名儿童和青少年替牙期及恒牙期错畸形进行临床体检和问卷调查。结果①本次调查得出的错畸形患病率为57.74%,其中,男性为59.52%,女性为55.50%,两者比较有统计学差异(P<0.05)。②错畸形安氏分类的构成比:Ⅰ类错>Ⅱ1类错>Ⅲ类错>Ⅱ2类错。③在错畸形临床表现中牙列拥挤的发病率为58.64%,居首位。结论太原市错畸形的患病率偏高,不同错类型有不同临床表现,应尽早有针对性地进行预防性矫治和阻断性矫治,同时,加强正畸宣教势在必行。
