Histological and immunohistochemical changes in facial skin treated with combined ablative and non-ablative laser therapy.

Background: Facial skin rejuvenation is a highly sought after procedure. Different materials, energy-based devices and techniques have been shown to offer good results in facial rejuvenation.

Aims: The aim of this study was to evaluate the macroscopic and histological and immunohistochemical changes in facial skin treated with a combined laser therapy.

Circadian dynamics in the functional interaction of the lateral teeth occlusal surfaces' relief.

Aim: This study describes the relationship of the chronophysiological organization of the lateral teeth occlusion and the parameters of the chewing unit of the human dentofacial system (bioelectric potentials, the force of the masticatory muscles, masticatory efficiency) which should be considered in modeling of prosthesis occlusal surfaces.

Materials And Methods: Examination of 200 respondents with a "day" chronotype, with Angle class I bilateral occlusion at the age of 18-35 years was conducted daily for 3 days. From 8.
