The management of residual periodontal pockets remains a challenge for Step 3 periodontal therapy. This systematic review aims to evaluate the potential and efficacy of the periodontal endoscope in managing residual periodontal pockets during Step 3 periodontal therapy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Material and Methods<\/jats:title>\n                    <jats:p>A comprehensive search was conducted in Medline, PubMed, Cochrane Library, Embase, Scopus, and Web of Science databases up to December 2024. Studies included were randomized controlled trials (RCTs) comparing periodontal endoscope\u2010assisted subgingival debridement (EASD) with repeated root surface debridement (RSD) and access flap periodontal surgery (AFPS). Data extraction and risk of bias assessment were performed independently by two reviewers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Five RCTs were included, involving 155 subjects and 4072 sites. EASD showed a significantly higher periodontal probing depth (PPD) reduction compared to repeated RSD, with a weighted mean difference (WMD) of 0.5\u2009mm (95% CI: 0.19\u20130.81) at 3\u2010month postoperation. At 6\u2010month postoperation, the WMD of PPD and clinical attachment level (CAL) changes were 0.84\u2009mm (95% CI: 0.60\u20131.09) and 0.89\u2009mm (95% CI: 0.45\u20131.34), respectively, in favor of EASD. EASD showed a significantly higher prevalence ratio (20%) of pocket resolution (PPD\u2009\u2264\u20094\u2009mm) compared to repeated RSD at 6\u2010month postoperation. No significant differences were observed between EASD and AFPS in the changes of CAL, PPD and prevalence of pocket resolution (PPD\u2009\u2264\u20094\u2009mm). The overall certainty of the evidence was deemed to be \u201clow\u201d for EASD versus repeated RSD comparisons and \u201cmoderate\u201d for EASD versus AFPS comparisons.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>EASD demonstrated superior clinical outcomes compared to repeated RSD in managing residual periodontal pockets.
