Accurate assessment of vascularization is essential for understanding periodontal and peri-implant wound healing, yet current clinical methods are limited by subjective interpretation and low reproducibility. Repeated LSCI measurements will be performed in healthy gingival tissues and in tissues undergoing different mucogingival healing patterns, including primary and secondary intention healing. The study will also evaluate factors that may influence perfusion readings, such as angulation, retractors, mirror use, temperature, and heart rate. The primary objective is to determine the reproducibility of LSCI measurements and to support its use as a reliable tool for monitoring oral soft-tissue vascularization and healing.",[74,75,17,76],"Gingival Vascularization","Oral Soft Tissue Wound Healing","Periodontal Wound Healing",[78,21,79,80,81,82,83,84,85,86,87],"Laser speckle contrast imaging","Gingival microcirculation","Oral soft tissue wound healing","Periodontal wound healing","Mucogingival surgery","Palatal donor site","Blood perfusion","Reproducibility","Reliability","PeriCam PSI","2026-04-17",{"date":90,"type":91},"2026-04-22","ACTUAL",{"date":93,"type":91},"2026-04-13",{"date":95,"type":68},"2026-05-20",{"name":5,"class":6},1]
