摘要
对４５例４８颗儿童期有症状畸形中央尖双尖牙（其中并牙髓炎１９颗占３９．６％，牙髓坏死１９颗占３９．６％和根尖病变１０颗，占２０．８％）行氢氧化钙根管充填根尖诱导形成术。经１至４年观察，牙根尖完全发育成形有７９．２％，根尖部分发育形成有１６．６％，失败有４．２％。认为临床上有效抗感染，恰当的根管预备和根管充填的条件下。
48 teeth with deformity central cusp from 45 children were selected in this study,there were 19 teeth(39.6%)of pulpitis,19 teeth (39.6%)of nonvital pulp and 10 teeth (20.8%) of periapical lesions.All of the selected teeth were treated by the apexification of root calcium hydroxide filling.Following up from one to four years the rates of complete apexogenesis,partial apexogenesis and failure were 81.3%,16.7% and 4.2% respectively.This finding suggested that with efficient antiinflammatory,correct root canal preparation and root canal filling clinically,calcium hydroxide can induce apexogenesis of infected deformity central cusp.
