目的观察早期发现、早期预防性治疗畸形中央尖的临床效果。方法对45例78颗萌出但尚未达到咬牙合平面的畸形中央尖,髓角未突入的患牙先间隔调磨2～3次,每次调磨<0.5mm,涂布氟化钠,然后再采用树脂充填、加固;髓角突入的患牙做直接盖髓术,双垫底后严密充填;对失败的病例则改做根尖诱导成形术。结果 78颗患牙中76颗治疗成功,2颗治疗失败,成功率为97.4%。结论对畸形中央尖早期发现,早期治疗,适时选择治疗方法,促进牙根继续发育,是早期畸形中央尖预防性治疗的一种较好的方法。
Objective To observe the early detection and early preventive treatment of deformity central point of the clinical effect. Methods 45 cases of 78 eruption but has not yet reached the bite plane deformity of the central tip, the pulp did not break into the teeth of the first interval to grind 2 to 3 times, each time the grinding <0.5mm, coated with sodium fluoride, and then The use of resin filling, reinforcement; pulp into the teeth with direct pulp capping surgery, double bottom after the close filling; failed cases were changed apical inductive angioplasty. Results 76 of 78 teeth were successfully treated and 2 failed. The success rate was 97.4%. Conclusion Early detection of deformity central point, early treatment, timely treatment of choice, and promote the continued development of the root, is a good method of prophylactic treatment of early deformity of the central tip.
