贵金属烤瓷全冠修复对牙周微生物的影响

The effect of the noble metal porcelain crown on the periodontal microbe

目的:探讨贵金属烤瓷冠的戴入对牙周细菌的影响。方法:采用经典细菌培养鉴定及菌落形成单位计数(CFU/mL)的检测方法,对临床病例进行前后自身对照取样。结果:戴牙后龈沟内牙周可疑病原菌与牙体预备前无显著差异,仅在戴牙后2周内消化链球菌和二氧化碳噬纤维菌与备牙前有显著性差异。结论:贵金属烤瓷牙长时间戴入对口腔局部龈沟菌群的影响可能较小。

AIM： To investigate the effect of the noble metal porcelain crown on the gingival gloove flora. METHODS： By using the classical bacterial incubation and CFU identification test method, the local gingival groove flora from clinical cases were sampled with self - control. RESULTS ： The CFU of most of bacteria had no significant changes except that capnocytopbaga and peptostreptocoecus significanly increased compared with the baseline two weeks after wearing the crown. CONCLUSION ： The noble metal porcelain restoration had little effect on the balance of the periodontal bacteria.
