Further rigorous and well\u2010designed bias\u2010controlled clinical trials are needed to confirm these findings and determine their relevance to clinical practice.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Plain Language Summary<\/jats:title>\n                    <jats:p>Cemental tears are a rare but serious dental issue that can lead to tooth loss, especially in older adults. They occur when a small piece of the tooth's root covering (cementum) breaks away, causing inflammation and bone loss. This study followed 41 patients who received regenerative surgical treatment using enamel matrix derivative and deproteinized porcine bone mineral to repair the damage. Over an average of 4 years, patients showed significant improvements in gum health and bone healing. Pockets around the teeth were reduced in depth, gum attachment improved, and bone defects decreased. Importantly, 90.2% of the treated teeth survived, showing the procedure's mid\u2010term effectiveness. These findings suggest that regenerative surgery using enamel matrix derivative and deproteinized porcine bone mineral can be a successful option for treating cemental tears, but further research is needed to refine treatment strategies and confirm these results in larger patient groups.<\/jats:p>\n
