The objective of the study is to evaluate the healing, regeneration and restoration processes occurring at gingival level after gingivectomy, performed either with or without laser therapy. 38 patients, with no systemic diseases, with gingival overgrowths requiring successive curative interventions at the level of the parodontium surface. In 21 patients, the surgical treatment was followed by laser therapy, applied daily, for 7 days. The healing process was relatively different in patients with no laser therapy, compared with those subjected to such treatment. In this respect, worth mentioning is the fact that, in the former case, the chronic-type inflammatory infiltrate persisted (although to a moderate amount, having in view the curettage moment) while, in the latter case, a significant reduction of the inflammatory infiltrate, was noticed. More than that, in patients with laser therapy, the epithelial-conjunctive interface showed important interdigitations, whereas, in the subjacent lamina propria, special mention should be made of the perpendicular arrangement of the newly-formed collagen particles, which made the restored mucous membrane have an increased resistance to mechanical aggressions. Laser-based therapeutic procedures increase the rhythm of plague healing, stimulating an early restoration of the injured tissues, and improving their quality in periodontal treatments.
