Minocycline hydrochloride slow-release antibacterial ointment in the treatment of combined periodontal-endodontic lesions / 中国组织工程研究

ABSTRACT

BACKGROUND:The role of minocycline hydrochloride in adjuvant therapy of chronic periodontitis and periodontal abscess has been widely reported, but detailed study of minocycline hydrochloride for combined periodontal-endodontic lesions is rare at present. OBJECTIVE:To investigate the effect of minocycline hydrochloride in the treatment of combined periodontal-endodontic lesions. METHODS:A total of 68 teeth with combined periodontal-endodontic lesions were treated with periodontal mechanical treatment and root canal therapy. According to the patient’s wiling, 68 patients were divided into experimental group (n=24; local injection of minocycline hydrochloride after periodontal mechanical treatment), positive control group (n=24; local injection of iodine glycerol after periodontal mechanical treatment), and negative control group (n=20; no injection after periodontal mechanical treatment). These three groups were reviewed 1 month after periodontal mechanical treatment, and the differences before and after treatment were compared, including periodontal probing depth, attachment loss and gingival bleeding index. RESULTS AND CONCLUSION: Probing depth, attachment loss and gingival bleeding index in three groups were significantly improved after 1 month of periodontal mechanical treatment (P sulcus bleeding index in experimental group and positive control group were better than that of the negative control group (P of positive control group (P periodontal-endodontic lesions, in addition to periodontal mechanical treatment and root canal therapy, local application of minocycline hydrochloride can effectively reduce the depth of periodontal pocket, improve gingival inflammatory conditions and consolidate curative effect.
