To assess proximal contact tightness and contour of two different sectional matrix systems in class-II direct composite restoration using newly designed assessment criteria.
In a double-blinded randomized clinical trial, 62 class-II direct composite restorations were performed in 62 patients using (n = 31) and matrix systems (n = 31). Proximal contact tightness and contour were assessed using a self-designed criterion. Statistical analysis utilized and , with P < 0.001 considered significant.
The mean ± sd score for clinical and radiographical evaluation of proximal contact tightness of the group (1.06 ± 0.25) was statistically significant with a p-value (<0.001) compared to the group (2.39 ± 0.72).
The study found that the Bioclear Biofit HD matrix system demonstrated better proximal contact and contour than the Sectional Matrix System in Class-II direct composite restorations.
使用新设计的评估标准,评估两种不同的分段式成型片系统在II类直接复合树脂修复中近中接触的紧密程度和外形。
在一项双盲随机临床试验中,62例患者接受了62次II类直接复合树脂修复,其中31例使用[具体名称1]成型片系统,31例使用[具体名称2]成型片系统。使用自行设计的标准评估近中接触的紧密程度和外形。统计分析采用[具体统计方法1]和[具体统计方法2],P < 0.001被认为具有统计学意义。
[具体名称1]组近中接触紧密程度的临床和影像学评估的平均±标准差分数为(1.06 ± 0.25),与[具体名称2]组(2.39 ± 0.72)相比,p值(<0.001)具有统计学意义。
研究发现,在II类直接复合树脂修复中,Bioclear Biofit HD成型片系统比[具体名称2]分段式成型片系统具有更好的近中接触和外形。
