This study aimed to investigate the operator's ease, satisfaction, and comfort of using a circumferential matrix system and sectional matrix system on the proximal contact points and contours when restoring class II cavities in posterior teeth.
This cross-sectional study was performed at the clinics in the Department of Conservative Dental Sciences, College of Dentistry, Qassim University. A total of 105 dental students randomly participated in this study to restore a class II cavity with direct composite resin restoration. Operators' comfort and satisfaction were evaluated according to their assessment of the contact points they reproduced and the emergence profiles of restorations, using a circumferential matrix system and sectional matrix system.
Out of 105 operators, 57 were satisfied with using circumferential matrix bands for most of their cases while 78 of the operators were satisfied with sectional matrix bands. There were no significant differences between operator satisfaction and the use of circumferential matrix band system (P > 0.05) and sectional matrix band system (P = 0.134) but there was a significant difference between difficulty levels in the use of both matrix band systems (P < 0.05; P = 0.000).
Circumferential and sectional matrix band systems showed no significant differences with operators' satisfaction during restoring class II cavities in posterior teeth but using a sectional matrix band system was considered easier than using a circumferential matrix band system.
本研究旨在调查在修复后牙Ⅱ类洞时,使用环形矩阵系统和分段矩阵系统处理近中接触点和外形时,操作者的操作便利性、满意度和舒适度。
本横断面研究在卡西姆大学牙科学院保守牙科学系的诊所进行。共有105名牙科学生随机参与本研究,用直接复合树脂修复Ⅱ类洞。根据操作者对所恢复的接触点和修复体边缘外形的评估,使用环形矩阵系统和分段矩阵系统评估操作者的舒适度和满意度。
在105名操作者中,57名在大多数病例中对使用环形矩阵带感到满意,而78名操作者对分段矩阵带感到满意。操作者满意度与使用环形矩阵带系统(P>0.05)和分段矩阵带系统(P = 0.134)之间无显著差异,但两种矩阵带系统的使用难度水平之间存在显著差异(P<0.05;P = 0.000)。
在修复后牙Ⅱ类洞时,环形和分段矩阵带系统在操作者满意度方面无显著差异,但使用分段矩阵带系统比使用环形矩阵带系统更容易。
