前言：本研究的目的是探讨在二极管激光或氯己定凝胶两种临床治疗方法的辅助下，SRP与单独使用SRP的效果。方法：选择8例中重度慢性牙周炎患者，每位患者至少有3个袋深4 ~ 7mm。随机选择66个囊袋，分别采用单纯刮除和根规划（SRP）、SRP +二极管激光（1.5 W,980 nm，30秒，连续波）（激光组）、SRP +洗己定凝胶-黄原胶（凝胶组）进行治疗。测量并评价治疗前、治疗后1个月、治疗后3个月的临床指标（探查袋深度[PPD]、临床附着水平[CAL]、乳头状出血指数[PBI]平均评分）和微生物指标（细菌总数[TBC]）。结果：在随访1个月和3个月时，氯己定凝胶和二极管激光辅助SRP治疗在降低PPD、改善临床CAL、降低PBI平均评分和TBC方面均优于单纯SRP治疗（p < 0.05）。激光组与凝胶组的临床指标在随访各阶段比较均无显著差异，但在随访3个月时，激光组TBC减少量显著高于凝胶组（P < 0.05）。结论：与单用SRP治疗相比，用二极管激光或氯己定凝胶辅助治疗可改善牙周及微生物指标。二极管激光长期杀菌效果较好。
Introduction: The aim of the present study was to investigate the effects of SRP assisted by the two clinical treatment methods of diode laser or Chlorhexidine Gel applications in comparison with SRP alone. Methods: Eight patients with moderate to severe chronic periodontitis, each with at least three pockets 4–7 mm deep, were selected for this study. Over 66 pockets were selected and randomly treated by either scaling and root planning (SRP) alone, or by SRP + diode laser (1.5 W,980 nm,30sec, continuous wave)(laser group),or by SRP + chlorhexidine gel-xanthan based (gel group). The clinical indices (probing pocket depth [PPD], clinical attachment level [CAL], and papillary bleeding index [PBI] mean score) and microbiological index (total bacterial count [TBC]) before, 1 month and three months after treatment were measured and evaluated. Results: The results showed that SRP assisted by chlorhexidine gel and diode laser therapies exhibits better results than SRP alone in reducing PPD, improving clinical CAL, and reducing PBI mean score and TBC (p < 0.05) both at one month and three months follow ups. Comparison of clinical indices between the laser group and the gel group showed no significant differences at neither of the follow up stages, but in 3 months follow up interval, the TBC reduction in the laser group was significantly more than the gel group (P < 0.05). Conclusion: Treatment with diode laser or chlorhexidine gel as an adjunct to SRP may improve periodontal and microbiological indices compared to SRP alone. Diode laser showed better bactericidal effects in long term.
