Efficacy of minocycline hydrochloride combined with flap surgery for chronic periodontitis: a Meta-analysis / 华西口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>This study aimed to evaluate the efficacy of 2% minocycline hydrochloride combined with flap surgery in the treatment of chronic periodontitis. The superiority of this therapy to simple flap surgery was also explored.</p><p><b>METHODS</b>We searched the databases of CNKI, VIP, Wanfang, Chinese Biomedical Literature, PubMed, ScienceDirect, and Embase from inception to July 2017. Two reviewers independently screened literature, extracted data, and evaluated the bias risk of included studies. Then, Meta-analysis was performed using RevMan 5.3 software.</p><p><b>RESULTS</b>A total of seven randomized controlled trials involving 217 patients were included. Meta-analysis showed that, in two groups, the changes in probing depth (PD) [MD=-0.55, 95%CI (-0.84, -0.26), P=0.000 2] and plaque index [MD=-0.08, 95%CI (-0.15, -0.01), P=0.03] at 3 and 6 months of PD [MD=-0.62, 95%CI (-1.04, -0.21), P=0.003] had statistically significant difference (P<0.05). The clinical attachment loss (CAL) [MD=-0.21, 95%CI (-0.47, 0.04), P=0.10] had no statistically significant difference after 3 months (P>0.05), but the improvement in CAL was significantly improved by minocycline hydrochloride combined with flap therapy.</p><p><b>CONCLUSIONS</b>Periodontal flap combined with minocycline adjuvant therapy for chronic periodontitis is effective in short-term observations.</p>
