Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Researchers will compare the use of mucotome, Er:YAG laser, surgical diamond bur, or blade to observe patterns of wound healing and assess if one method is superior in terms of removing the epithelium.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Subjects undergoing periodontal surgical procedures that involve harvesting of soft tissue samples, who have a treatment plan including the use or removal of keratinized mucosa or subepithelial connective tissue that will not require additional anesthesia for sample collection
* Adequate physical and mental health to undergo routine dental treatment
* Ability and willingness to follow instructions related to the study procedures
Exclusion Criteria
* Autoimmune or inflammatory conditions such as systemic lupus erythematous, rheumatoid arthritis.
* Pregnant women or nursing mothers, or unsure of pregnancy status (self-reported)
* Severe hematologic disorders, such as leukemia or hemophilia
* Subjects on anticoagulant or antiplatelet therapy
* Local or systemic infection that may interfere with healing
* Hepatic or renal diseases
* Currently under cancer treatment or within 18 months from completion of radio- or chemotherapy
* History of antibiotic or immunosuppressant use in the last 3 months
* Subjects on concomitant drug therapy for systemic conditions that may affect outcomes of the study
* Current smokers (CDC definition): heavy smokers: subjects who have smoked \>10 cigarettes per day within 6 months of study onset, and have smoked \>100 cigarettes in their lifetime
