Randomized controlled trials (RCTs) with 1 month of follow-up period were selected. Two reviewers extracted data from selected studies independently. Cochrane collaboration's tool for assessing risk of bias was used for assessing the quality of the RCTs. The random-effects model was employed for meta-analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>One thousand fifteen studies were initially identified. Finally, nine RCTs were included for quality assessment and seven studies for meta-analysis. Four RCTs were of unclear risk of bias and five were assessed as high risk of bias. The comparison showed no significant differences for pain scores [visual analog scale (VAS)] [mean differences (MD)\u2009=\u20090.38, confidence interval (CI)\u2009=\u200995% \u22120.64 to 1.40] and severity scores (reticular\u2013atrophic\u2013erosive scores) (MD\u2009=\u20091.67, CI\u2009=\u200995% \u22121.13 to 4.46) between topical corticosteroid therapy and PBMT after 1 month. For PDT, no significant differences were observed for sign scores (Thongprasm sign scoring) (MD\u2009=\u2009\u22120.31, CI\u2009=\u200995% \u22121.52 to 0.91) and pain scores (VAS) (MD\u2009=\u2009\u22122.30, CI\u2009=\u200995% \u22125.88 to 1.28) of the lesions when compared with topical corticosteroid therapy after 1 month of follow-up period.
