Abstract

Purpose: Multiple accessory canals make furcation area of primary molars the most common port of entry of bacterial endotoxins to periradicular area. Reduction in permeability can improve prognosis of these teeth. Therefore, this study was designed to compare the effect of 940 nm diode laser and dentin bonding agent on the dye penetration of furcation area in primary molars.

Material and methods: Thirty teeth were divided into three groups, that is, Group 1 (control group), Group 2 (dentin bonding agent applied over floor of pulp chamber), and Group 3 (diode laser irradiated over floor of pulp chamber). The samples were prepared and seven from each group were tested by dye penetration and three were sent for scanning electron microscopy. Rise in temperature in the perifurcal area was also recorded at the time of laser irradiation. Dunn's pair-wise comparison analysis was used for the analysis for the difference in dye penetration among the group.

Results: : The maximum rise in temperature recorded postirradiation was 6.90C. Dye penetration was significantly reduced in Group 2 Dentin bonding group (DBG) as compared to control group (P = 0.0025). Reduction in permeability was observed in Group 3 Laser group (LG) but this was not statistically significant (P = 0.197). Scanning electron microscope revealed open dentinal tubules in Group 1. There were no open dentinal tubules in Group 2, while Group 3 had sealed dentinal tubules with glass-like surface over the region.

Conclusion: Dentin bonding agent led to substantial decrease in dye penetration of furcation area of primary molars. This method should be evaluated clinically to improve successful pulpectomy procedures of primary molars.

940 纳米二极管激光照射和牙本质粘接剂对初级磨牙窝沟区渗透性的影响。
目的:初级磨牙的毛囊区有多个附属根管,是细菌内毒素进入根周的最常见通道。降低渗透性可以改善这些牙齿的预后。因此,本研究旨在比较 940 纳米二极管激光和牙本质粘接剂对初级磨牙窝洞区染料渗透的影响:将 30 颗牙齿分为三组,即第 1 组(对照组)、第 2 组(在髓室底面涂抹牙本质粘接剂)和第 3 组(在髓室底面照射二极管激光)。制备样品后,每组选取 7 个样品进行染料渗透测试,3 个样品送去进行扫描电子显微镜检查。在激光照射时还记录了髓周温度的升高。采用邓恩配对比较法分析各组间染料渗透的差异:结果:辐照后记录到的最高温度升高为 6.90 摄氏度。与对照组相比,第 2 组牙本质粘接组(DBG)的染料渗透率明显降低(P = 0.0025)。第 3 组激光组(LG)的渗透性有所降低,但无统计学意义(P = 0.197)。扫描电子显微镜显示,第 1 组有开放的牙本质小管,第 2 组没有开放的牙本质小管,而第 3 组有密封的牙本质小管,该区域表面呈玻璃状:结论:牙本质粘接剂可大大降低染料对初级磨牙沟区的渗透。应在临床上对这种方法进行评估,以提高初级磨牙牙槽切除术的成功率。
