A portion of the CTG obtained from the peripheral trimmed area was biopsied and histologically examined. De\u2010epithelialization of this area was performed using the same protocol as in the clinical procedure, including both Er:YAG laser irradiation and adjunctive rotary brush application, suggesting that epithelial removal was achieved in the examined sample with minimal damage to the underlying connective tissue layer of dense collagen fibers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>By effectively eliminating epithelial remnants and preserving connective tissue thickness in palatal grafts, EL\u2010DGG can offer more favorable clinical outcomes in root coverage and ridge augmentation compared to conventional graft\u2010harvesting methods.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Key points<\/jats:title>\n                    <jats:p>\n                      <jats:list list-type=\"bullet\">\n                        <jats:list-item>\n                          <jats:p>\n                            <jats:bold>Selective epithelial removal<\/jats:bold>\n                            : Intraoral Er:YAG laser\u2010assisted de\u2010epithelialization enables selective removal of palatal epithelium while preserving dense subepithelial connective tissue thickness.\n                          <\/jats:p>\n                        <\/jats:list-item>\n                        <jats:list-item>\n                          <jats:p>\n                            <jats:bold>Histologic and clinical validation<\/jats:bold>\n                            : Histologic analysis confirmed complete epithelial elimination with minimal lamina propria damage, resulting in stable root coverage and soft tissue augmentation.\n                          <\/jats:p>\n                        <\/jats:list-item>\n                        <jats:list-item>\n                          <jats:p>\n                            <jats:bold>Advantage in thin phenotypes<\/jats:bold>\n                            : This technique allows predictable graft harvesting even in thin palatal mucosa, supporting phenotype modification and ridge augmentation procedures.\n                          <\/jats:p>\n                        <\/jats:list-item>\n                      <\/jats:list>\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Plain Language Summary<\/jats:title>\n                    <jats:p>Gum tissue taken from the roof of the mouth is commonly used to cover exposed tooth roots or rebuild areas where soft tissue has been lost. However, when preparing these grafts with a scalpel, small remnants of the surface epithelial layer may remain, while removing too much tissue can reduce the thickness and quality of the connective tissue needed for treatment. In this case series, we used an Er:YAG laser to remove the epithelial layer directly from the palate before harvesting the graft. This approach was used in three patients: two received treatment for exposed tooth roots, and one received soft tissue augmentation in an area with a missing tooth. Complete root coverage was achieved in both root coverage cases, and an increase in tissue volume was observed in the ridge augmentation case. Microscopic examination of a graft sample suggested that the epithelial layer was removed while the dense connective tissue underneath was largely preserved. These findings suggest that Er:YAG laser\u2010assisted graft preparation may help clinicians obtain thick, stable connective tissue grafts while reducing unwanted epithelial remnants. Further studies involving more patients and longer follow\u2010up are needed to confirm these potential benefits.<\/jats:p>\n
