目的评价口腔护理对全冠修复后口腔卫生的影响。方法 60例右下颌第一磨牙烤瓷全冠修复患者,选择右下颌第一磨牙作为测试牙,对侧同名牙作为对照牙,比较烤瓷全冠和对侧同名牙口腔护理前后的牙菌斑指数(PLI)。结果烤瓷全冠组和对照牙组护理前后PLI差异有统计学差异(P<0.01);组间比较:护理前及护理后2组PLI差异无统计学意义(P>0.05)。结论制作精良的烤瓷全冠修复不会造成患者的牙周损害,棉球擦拭法能有效去除全冠修复体和正常牙齿表面的牙菌斑,口腔护理可以改善全冠修复后患者的口腔卫生状况。
Objective To evaluate the effect of oral care on oral hygiene after crown restoration. Methods Sixty patients with right lower mandibular first molar were treated with porcelain crowns. The first molar of the right lower jaw was selected as the test tooth and the same name of the contralateral tooth as the control tooth. The dental plaque before and after the same porcelain crown and contralateral dental care were compared Index (PLI). Results There were significant differences in PLI before and after treatment between PFM group and control tooth group (P <0.01). There was no significant difference in PLI between two groups before and after nursing (P> 0.05). Conclusion The well-made porcelain full-crown restoration will not cause periodontal damage in patients. The cotton ball wiping method can effectively remove the plaque on the crown restoration and the normal tooth surface. Oral care can improve oral hygiene in patients with full crown restoration situation.
