Background/Purpose. To evaluate and compare the marginal leakage and shear bond strength between conventional and Papacarie techniques of caries removal in primary molars. Materials and Methods. Sixty freshly extracted human carious primary molars were randomly divided into two groups: group I-caries removal by conventional method and group II-caries removal using Papacarie. After bonded restorations, both groups were further randomly subdivided into four subgroups for marginal leakage and shear bond strength evaluation. Results. Papacarie treated teeth (46.70%) showed less marginal leakage when compared to conventionally treated teeth (86.70%) for caries removal. The mean shear bond strength was found more in Papacarie treated teeth (12.91 MPa) than in those treated conventionally (9.64 MPa) for caries removal. Conclusion. Papacarie showed less marginal leakage and more shear bond strength when compared to those treated conventionally for caries removal.
背景/目的。评估并比较乳牙常规去龋技术与Papacarie去龋技术之间的边缘渗漏和剪切粘结强度。材料与方法。60颗新鲜拔除的人类龋坏乳牙随机分为两组：第一组采用常规方法去龋，第二组采用Papacarie去龋。粘结修复后，两组再进一步随机分为四个亚组，用于边缘渗漏和剪切粘结强度评估。结果。在去龋方面，与常规治疗的牙齿（86.70%）相比，Papacarie治疗的牙齿边缘渗漏较少（46.70%）。发现Papacarie治疗的牙齿去龋后的平均剪切粘结强度（12.91MPa）高于常规治疗的牙齿（9.64MPa）。结论。与常规去龋治疗相比，Papacarie去龋边缘渗漏更少，剪切粘结强度更高。
