Laser photobiomodulation effect on fibroblasts viability exposed to endodontic medications

Recent Advances on the Use of Laser Photobiomodulation on Bone

Laser Phototherapy (LPT) is an effective tool to stimulate bone. A series of promising protocols developed by our group are presented. Our results show that the use of IR laser results on increased bone neorformation. LPT effect depends not only on the total dose, but also on both irradiation time and mode. Energy density and intensity are biologically independent and accounts for the success a...

Photobiomodulation Laser Strategies in Periodontal Therapy

Laser is considered basically effective for treating periodontal diseases because of its excellent physical properties namely ablation, hemostasis, bacterial killing and cell stimulation. The current laser application mainly used for the treatment of periodontitis is high-power laser ablation (HLLT). Laser ablation of diseased periodontal tissues using the HLLT is widely performed, partly expec...

Effect of time of extraction on the biocompatibility of endodontic sealers with primary human fibroblasts.

The aim of this work was to evaluate the effects of different times of extraction on the cytotoxicity of six representatives of different root canal sealer groups-Real Seal SE, AH Plus, GuttaFlow, Sealapex, Roth 801, and ThermaSeal Plus-with human gingival fibroblasts. The materials were prepared according to manufacturers' specifications, and were incubated in culture medium (DMEM) at 37ºC for...

Protective Effects of Simvastatin on Cytotoxicity and Oxidative Stress in Human Gingival Fibroblasts Cells Exposed to Venlafaxine

Background and purpose: Venlafaxine is an antidepressant that belongs to the family of selective serotonin and norepinephrine reuptake inhibitor (SNRIs) drugs. Recent studies have indicated that prolonged use of antidepressants leads to a state where increased formation of reactive oxygen species (ROS) overwhelms body antioxidant protection and subsequently induces DNA damage, lipid peroxidatio...
