This study evaluated and compared the effects of argon laser and visible light polymerization of a pit and fissure sealant material on caries-like lesion initiation and progression. Following the lesion initiation period, the primary surface lesion depth was significantly less (P < 0.05) for the argon laser-cured group (97 microns) when compared with that for the visible light-cured group (151 microns). Wall lesion occurrence was 5% for both treatment groups. Following lesion progression, the primary surface lesion depth was significantly less (P < 0.05) for the argon laser-cured group (129 microns) when compared with that for the visible light-cured group (232 microns). Wall lesion occurrence was 15% and 5% for visible light-cured and argon laser-cured groups, respectively (P < 0.05). Argon laser-curing of sealant material may enhance the caries resistance of the enamel forming the enamel-resin interface and result in a reduction in caries formation adjacent to sealants.
本研究评估并比较了氩激光和可见光对窝沟封闭剂材料进行聚合处理后，对类龋损起始和进展的影响。在龋损起始期后，与可见光固化组（151微米）相比，氩激光固化组（97微米）的初始表面龋损深度显著更浅（P < 0.05）。两个治疗组的壁龋发生率均为5%。在龋损进展期后，与可见光固化组（232微米）相比，氩激光固化组（129微米）的初始表面龋损深度显著更浅（P < 0.05）。可见光固化组和氩激光固化组的壁龋发生率分别为15%和5%（P < 0.05）。对封闭剂材料进行氩激光固化可能会增强形成釉质-树脂界面的釉质的抗龋能力，并减少封闭剂附近的龋齿形成。
