Cracked teeth of different stages of lesions pulp treatment clinical curative effect observation

目的探讨隐裂牙护髓治疗在不同病变发展阶段的疗效及牙髓保守治疗的最佳时机。方法选取2011年-2013年我院收治的隐裂牙患者215例（患牙215颗）,依据不同病变阶段为分A组和B组,A组105颗,患者无牙髓炎症状;B组110颗,患者有可复性牙髓炎症状。对两组患牙进行护髓治疗,并随访观察2周-1年。结果 A组患牙治疗成功85颗,有效12颗,失败8颗,成功率为81%;B组患牙治疗成功32颗,有效30颗,失败48颗,成功率为29%。A组成功率显著高于B组,差异有统计学意义（P〈0.05）。两组中上颌前磨牙与下颌前磨牙的成功率对比,差异无统计学意义（P〉0.05）;B组中上颌磨牙与下颌磨牙的成功率与A组比较,差异有统计学意义（P〈0.05）。结论早期发现及早期诊断是隐裂牙护髓治疗成功的关键,在隐裂牙的可复性牙髓炎前期进行护髓治疗能最大限度的保留患牙,防止牙齿的早失。

Results Group A had successful treatment of 85,the effectived was 12,the failured was 8,the success rate was 81%.Group B had successful treatment of 32,the effectived was 30,the failured was 48,the success rate was 29%.Group A was significantly higher than group B（P〈0.05）.The success rate of maxillary premolar and mandibular premolar between Group A and B was no significant difference（P〉0.05）.The success rate of mandibular molar in group B was more significant difference than in group A（P〉0.05）. Conclusion Earlier detection and earlier diagnosis is the key of successful treatment to cracked teeth,cracked teeth of pre-marrow treatment can be the maximize protected to retention the pulpitis of teeth,and prevent the loss of teeth in earlier.
