Two hundred direct pulp capping procedures were conducted in the present study. One hundred of them were performed with the CO2 laser, and 100 were conducted conventionally as a control by using a calcium hydroxide preparation. Follow-up examinations were performed after 1 wk and monthly for 12 months after treatment. Thermal tests were used for vitality assessments and laser Doppler flowmetry for direct measurement of pulpal blood. In the group of pulps treated with the CO2 laser, the last recall examination at 12 months demonstrated that 89 teeth remained vital, corresponding to a success rate of 89%. In the control group, the success rate was considerably lower (68%). Exposure sizes and mean patient age were nearly identical in both groups. The CO2 laser seems to be a valuable aid in direct pulp capping.
本研究进行了200次直接盖髓术。其中100次使用二氧化碳激光进行，另外100次作为对照采用常规氢氧化钙制剂进行。治疗后1周进行随访检查，并在之后12个月每月进行一次。采用热测试评估牙髓活力，并用激光多普勒血流仪直接测量牙髓血流。在接受二氧化碳激光治疗的牙髓组中，12个月时的最后一次复查显示89颗牙齿仍保持活力，成功率为89%。在对照组中，成功率则低得多（68%）。两组的暴露面积和患者平均年龄几乎相同。二氧化碳激光似乎是直接盖髓术中一种有价值的辅助手段。
