目的比较三种不同治疗方法在可摘局部义齿前部基牙邻面龋治疗中的作用效果。方法按照龋病诊断标准将216例基牙随机分为3组,直接充填组:直接充填龋损基牙;扩展充填组:扩展至基牙整个邻面充填;全冠修复组:全冠修复龋损基牙,在可摘义齿戴入后12、24、36个月复查,分别对3组继发龋发生率进行比较。结果直接充填法治疗的前部基牙继发龋发病率明显高于扩展充填组和全冠修复组,差异有统计学意义(P<0.05),扩展充填组的前部基牙继发龋发病率高于全冠修复组,差异有统计学意义(P<0.05)。结论简单充填并不能有效地阻止前牙邻面继发龋的发生,而做相应扩展充填尤其是全冠修复后,避免了继发龋的发生,减少了基牙的损坏,从而延长修复体的使用寿命。
Objective To compare the effects of three different treatments on the treatment of abutment caries in the anterior abutments of removable partial dentures. Methods 216 cases of abutments were randomly divided into 3 groups according to the criteria of dental caries diagnosis. The direct filling group was directly filled with carious abutments. The extended filling group was extended to the entire abutment of abutments. The full crown repair group: Damage to the abutments, 12,24,36 months after the removal of removable denture re-examination, respectively, the incidence of secondary caries in three groups were compared. Results The incidence of secondary caries in the anterior abutment treated with direct filling was significantly higher than that in the extended and full crowns (P <0.05). The anterior caries in the anterior filling group Rate was higher than that of the whole crown repair group, the difference was statistically significant (P <0.05). Conclusions Simple filling can not effectively prevent the occurrence of secondary caries in the anterior surface of the anterior teeth. However, after the corresponding filling, especially the crown restoration, avoids the occurrence of secondary caries, reduces the damage to the abutments and prolongs the restoration Service life.
