目的:比较Diode激光辅助牙周基础治疗(实验组)与单纯牙周基础治疗(对照组)对服用钙通道拮抗剂老年患者龈沟出血的改善效果。方法:选择10位服用钙通道拮抗剂的老年患者共30颗牙,左右对称,随机确定一侧为实验组,对侧牙为对照组。口腔卫生宣教和龈上洁治后2周为基线,治疗2周、4周、8周后记录龈沟出血指数(SBI),并进行统计分析。结果:实验组和对照组的SBI在2周、4周和8周后与基线比较均有明显改善(P<0.01);两组之间比较,SBI的改善没有明显差异(P>0.01);实验组中、深牙周袋位点SBI的改善较浅袋明显(P<0.01),对照组不同袋深位点SBI的改善没有明显差异(P>0.01)。结论:Diode激光辅助牙周基础治疗能显著改善服用钙通道拮抗剂老年患者的SBI,尤其在中深牙周袋位点;Diode激光辅助牙周基础治疗与牙周基础治疗在SBI改善的差异上没有显著性。
Objective: To compare the effect of Diode laser-assisted periodontal treatment (experimental group) and simple periodontal treatment (control group) on the improvement of sulcus bleeding in elderly patients taking calcium channel blocker. Methods: Ten elderly patients with calcium channel blockers were selected and their left and right symmetry were selected. One side was randomly selected as experimental group and the other side as control group. Oral hygiene education and 2 weeks after supragingivalgia were taken as baseline, and the sulcus bleeding index (SBI) was recorded after 2, 4 and 8 weeks of treatment, and statistical analysis was performed. Results: Compared with baseline, the SBI of experimental group and control group were significantly improved at 2 weeks, 4 weeks and 8 weeks (P <0.01). There was no significant difference of SBI between the two groups (P> 0.01). In the experimental group, the improvement of SBI in deep periodontal pouch was more obvious than that in shallow pouch (P <0.01). There was no significant difference in the improvement of SBI between different pockets (P> 0.01) in control group. Conclusion: Diode laser-assisted periodontal treatment can significantly improve the SBI in elderly patients with calcium channel blockers, especially in the middle-deep periodontal pocket. The difference between the improvement of SBI and Diode laser-assisted periodontal treatment and periodontal treatment No significance.
