Little information exists on the clinical performance of restorative materials on primary teeth of preschool children. This study aimed to evaluate clinical performance of compomer, glass-hybrid-added high-viscosity glass-ionomer cement and zinc-added high-viscosity glass-ionomer cement materials in class ΙΙ restorations of primary molars.
The study included 251 teeth of 57 patients aged 4-7 years with proximal caries in primary molars. The teeth were divided into three groups, and each restorative material was randomly distributed. Dyract XP, Equia Forte and ChemFil Rock materials were placed after cavity preparation and clinically evaluated at 3, 6, 9 and 12 months using modified United States Public Health Service criteria. Statistical analyses were performed using chi-square and z tests.
At the end of 12 months, a total of three restorations in Dyract XP group, 22 in Equia Forte group and 11 in ChemFil Rock group failed in retention criteria. No statistically significant difference existed between retention, colour match and surface texture criteria of all groups at 3 and 6 months, but a statistically significant difference was found at 12 months (P < 0.05).
For class ΙΙ restorations of primary molars, the success of compomer material was superior to high-viscosity glass-ionomer materials.
关于学龄前儿童乳牙修复材料的临床性能，相关信息较少。本研究旨在评估复合体、玻璃混合添加高粘度玻璃离子水门汀和锌添加高粘度玻璃离子水门汀材料在乳磨牙 I 类修复中的临床性能。
该研究纳入了 57 名年龄在 4-7 岁之间的患者的 251 颗近端有龋的乳磨牙。这些牙齿被分为三组，每组随机分配一种修复材料。在窝洞预备后，使用 Dyract XP、Equia Forte 和 ChemFil Rock 材料，并在 3、6、9 和 12 个月时使用改良美国公共卫生服务标准进行临床评估。采用卡方检验和 z 检验进行统计分析。
在 12 个月结束时，Dyract XP 组共有 3 个修复体、Equia Forte 组有 22 个修复体和 ChemFil Rock 组有 11 个修复体在保留标准上失败。在 3 个月和 6 个月时，所有组的保留、颜色匹配和表面纹理标准均无统计学差异，但在 12 个月时存在统计学差异（P<0.05）。
对于乳磨牙 I 类修复，复合体材料的成功率优于高粘度玻璃离子水门汀材料。
