Direct pulp capping is a minimally invasive method to preserve pulp integrity. We evaluated the treatment efficacy of Er:YAG laser irradiation combined with direct pulp capping for pulp exposure due to caries. A total of 21 patients with 22 teeth were enrolled in the conventional group (calcium hydroxide), and 24 patients with 25 teeth were enrolled in the laser-assisted group (Er:YAG laser irradiation at settings of 10 Hz, 50 mJ; combined with calcium hydroxide). The cumulative success rate of the conventional group and the laser-assisted group was 68.2% and 91.7% at 12 months, respectively. Results showed that the laser-assisted procedure increased the survival time (β = 0.04, OR = 0.07), while proximal-occlusal cavities in molars decreased the survival time (β = 0.03, OR = 12.5). Er:YAG lasers improve the effectiveness of conventional direct pulp capping (using Dycal) with limited side-effects and can be applied clinically.
直接盖髓术是一种保留牙髓完整性的微创方法。我们评估了铒激光照射联合直接盖髓术治疗龋源性露髓的疗效。常规组（氢氧化钙）纳入了21例患者的22颗牙齿，激光辅助组（设置为10赫兹、50毫焦的铒激光照射；联合氢氧化钙）纳入了24例患者的25颗牙齿。12个月时，常规组和激光辅助组的累积成功率分别为68.2%和91.7%。结果显示，激光辅助治疗延长了存活时间（β = 0.04，比值比 = 0.07），而磨牙近中 - 咬合面龋洞则缩短了存活时间（β = 0.03，比值比 = 12.5）。铒激光可提高传统直接盖髓术（使用Dycal）的有效性，且副作用有限，可应用于临床。
