Study and evaluation of the gubernacular canal by means of cone beam computed tomography.

The aims of this review of the literature were to conceptualize the gubernacular canal, by an approach to its function, importance and characteristics of its image in Cone Beam Computed Tomography. The bibliographic survey of scientific articles was conducted in the following databases: PubMed, Bireme, Scielo and Google Scholar. The gubernacular canal, which carries the gubernacular cord within it, is an anatomic structure that starts in the dental follicle and goes through to the alveolar bone crest behind the deciduous tooth.

Mast cells and its relation to collagen and VEGF in oral inflammatory lesions.

Background: The aim of this study was to evaluate the population of intact and degranulated MCs in oral inflammatory lesions.

Methods: A cross sectional study of 48 samples, including inflammatory fibrous hyperplasia, pyogenic granulomas, periapical granulomas and radicular cysts, was performed. Samples of normal gingival mucosa were used as controls.

Evaluation of corticosterone and IL-1β, IL-6, IL-10 and TNF-α expression after 670-nm laser photobiomodulation in rats.

The literature has shown that low-level laser therapy accelerates the repair of cutaneous wounds. However, there is a scarcity of scientific studies that characterise the possible systemic interference of laser photobiomodulation. The aim of this research was to quantitatively evaluate blood corticosterone levels and tissue cytokine expression in cutaneous wounds of rats treated with low-level laser therapy (semiconductor diode AsGaAl, continuous emission, 9 mW, 670 nm, 0.
