摘要
目的:评价在成对后牙邻牙合面成形时Palodent系统和普通成形系统的临床应用效果。方法:将符合纳入标准的102对成对的后牙邻牙合面洞随机分为试验组和对照组,每组各51对。充填时分别采用Palodent和普通成形系统,由同一名医师完成所有邻牙合面洞的充填工作。在充填后即刻、1周和1年由另一名医师通过临床检查和X线片对患牙充填后的舒适度、食物嵌塞、解剖外形、边缘嵴、邻接关系和牙龈炎症6项指标进行评价,比较2种成形系统的临床效果。结果:充填后即刻,在解剖外形、边缘嵴和邻接关系3个指标上Palodent组满意度为92.2%、88.2%、90.2%,普通成形系统满意度为76.5%、70.6%和74.5%,差异有显著性(P<0.05);充填后1周在舒适度、食物嵌塞、解剖外形、边缘嵴和邻接关系5个指标上,差异有显著性(P<0.05);充填后1年在舒适度、食物嵌塞、解剖外形、边缘嵴和邻接关系6个指标上差异亦有显著性(P<0.05)。结论:Palodent系统在线对后牙邻牙合面成形时比普通成形系统优势明显。
Objective： To compare the clinical effect of Palodent and circumferential matrix systems in tilting the paired posterior teeth. Methods： One hundred and two paired cavities with class lI cavities which met with the inclu- sion criteria were randomly divided into study group（Palodent group） and control group（ circumferential group）. One doctor--in--charge completed all the cavity filling. Immediately after cavity filling, one week later and one year later,questionnaires were filled by another doctor to evaluate the comfort level, food impaction, anatomical shape, marginal ridge, proximal contact and gum inflammation. Results： There were significant differences on indexes of comfort level, food impaction, anatomical shape, marginal ridge, proximal contact, gum inflammation between the two systems. Conclusion： Palodent matrix system is better than circumferential matrix system in filling the peired posterior teeth.
