Abstract

Abstract: Objective: To compare the therapeutic effects between dual-wavelength laser and minocycline hydrochloride on combined periodontal-endodontic lesions. Methods: Sixty teeth with combined periodontal-endodontic lesions were randomly divided into 2 groups, the experiment group (Nd: YAG disinfection after Root canal preparation + Er: YAG laser irradiation periodontal pocket) and the control group ( Iodine volts disinfection after Root canal preparation+ Minocycline hydrochloride in periodontal pocket). The difference in pain after 1 day between two groups was evaluated by visual analog scale (VAS). Periodontal pocket depth (PD), periodontal attachment level (CAL), and bleeding on probing (BOP) were compared between two groups after 1 week, 2 weeks, 3 weeks, 3 months, 6 months, and 1 year. Results: There were statistically significant difference in PD, CAL, and BOP between two groups. The experimental group was better than the control group. The bacteria were mainly Veillonellaceae, Streptococcaceae, Porphyromonadaceae, and Peptostreptococcaceae. Conclusion: Combination of Er: YAG laser and Nd: YAG laser is better than minocycline hydrochloride in treating combined periodontal-endodontic lesions.
