Effects of laser biostimulation on the epithelial tissue for keratinized layer differentiation: an in vitro study.

Effects of laser biostimulation on the epithelial tissue for keratinized layer differentiation: an in vitro study. J Biol Regul Homeost Agents. 2016 Apr-Jun;30(2 Suppl 1):99-105 Authors: Caccianiga G, Cambini A, Donzelli E, Baldoni M, Rey G, Paiusco A Abstract Gingival augmentation techniques proposed in the international literature do not exclude a surgical component, which determines consequent post-surgical discomfort and results are not always predictable. In recent years, the introduction of laser biostimulation has led to a less invasive approach, particularly in the treatment of periodontally compromised patients, limiting the surgical phase to seriously compromised cases, with regeneration techniques for the restoration of a correct periodontal tissue anatomy. The aim of this in vitro study is to establish the validity of laser biostimulation in order to develop the epithelial keratinized layer of the tissue by stimulating fibroblasts-keratinocytes organotypic cultures and fibroblasts and keratinocytes mono-cultures. We created two groups (test and control), each one composed of 3 fibroblast cultures, 3 keratinocyte cultures and 3 organotypic cultures. We performed laser irradiation of test group with Wiser Doctor Smile Lambda, Flat Top Handpiece, at 50 J/cm2 of fluency with one application every 40 h for a total of 5 applications. Forty-eight h after the last laser application, we investigated the presence and amount of kera...
