Does kinesio taping reduce pain, swelling, and trismus after mandibular third molar surgery? A systematic review and...

The aim of this study is to provide an evidence-based conclusion regarding the effectiveness of kinesio taping (KT) in reducing postsurgical discomforts after mandibular third molar surgery and critically appraise the available literature. Eligible clinical trials evaluating patients older than 18 years who were treated with any type of KT compared to no taping in which pain, swelling, or trismus scores were reported were included. An electronic literature search was carried out in the following databases to identify relevant papers up to May 30, 2021: Medline, Cochrane Central Register of Controlled Trials, Web of Science, and Scopus. The risk of bias was assessed using the Cochrane risk-of-bias tool for randomized trials (RoB 2.0). The effect sizes were calculated using mean difference (MD) and standardized mean difference (SMD). The heterogeneity analysis was conducted using (I²) statistic at alpha = 0.10 (PROSPERO; CRD42021252670). Nine randomized clinical trials with 444 participants were included in the qualitative analysis and eight in the quantitative analysis. The results of the meta-analysis revealed a statistically significant reduction in pain and swelling scores before the 7th postoperative day. On the 7th postoperative day, no significant difference was observed between KT and control groups in terms of pain and swelling. Additionally, KT led to an increase in patients' maximum mouth opening of more than 3 mm in postoperative intervals. KT is effective in reducing postoperative pain within the first 48 h after surgery and improving mouth opening during all postoperative intervals with moderate to high certainty of evidence.
