ABSTRACT
Chlorhexidine (CHX) is a prime choice to control the oral microbiota. However, it's a chemical agent leading to side effects such as teeth strains, taste disturbance, and desquamation of oral mucosa. Alternatively, the lactoferrin and oxygen-based Blue®M has been introduced as an alternative to the CHX, not disturbing tissue repair. Therefore, the study aimed to evaluate the effects of Blue®M and CHX on oral human fibroblasts (HGF-1) and keratinocytes (NOK-SI). Cell cultures using HGF-1 and NOK-SI evaluated cell proliferation, cell cycle, apoptosis and necrosis, and migration. In the dose-effect test, Blue®M reduced the HGF-1 sample in a 4-fold concentration than CHX (CHX 173.07 ±10.27; Blue®M 43.86 ±3.04). The proliferation test revealed an eightfold reduction of the sample for CHX, while for Blue®M, the proliferation rate was eighteen times lower. The apoptosis and necrosis rates increased by 25% (p<0.0001) for HGF-1 for both substances. In NOK-SI, the apoptosis rates increased by 10% (p=0.02) and 15% (p=0.001) for CHX and Blue®M, respectively. Furthermore, the fibroblast had a lower capacity for wound closure in the Scratch Assay (monolayer cell migration) for Blue®M. Despite the limitations of this in vitro study, the results of the lactoferrin and oxygen-based Blue®M demonstrated cytotoxicity in doses over the Minimum inhibitory concentration and Minimum bactericidal concentration for Oral fibroblasts (HGF- 1) and Keratinocytes (NOK-SI).
