Effects of diode laser therapy on the acellular dermal matrix.

Acellular dermal matrix (ADM) was subcutaneously implanted into calvarian skin of male Wistar rats (n = 40). Low-level laser (lambda 685 nm, 4 J/cm(2)) was locally applied in experimental group (n = 20) above the skin flap. Grafts were harvested at 1, 3, 7 and 14 days after surgery and underwent histological analyses.

Effects of laser therapy on experimental wound healing using oxidized regenerated cellulose hemostat.

Objective: The aim of this paper was to evaluate if the healing of wound sites containing oxidized regenerated cellulose hemostat can be optimized by laser therapy.

Background Data: Topical hemostatic agents may be used to control bleeding in a variety of surgical sites. Hemostatic oxidized regenerated cellulose can cause strange body reactions and formation of granulomas.

Submandibular gland sialolith in a renal transplant recipient: a case report.

Salivary dysfunction may be due to systemic diseases and medications. The development of sialoliths is a multifactorial event in which disturbances in secretion, microliths, and bacteria may play a major role. A case of sialolith in the submandibular gland of a 58-year old woman, with a medical history of renal failure end kidney transplant, is reported.

[Genotoxic effect of ethanol on oral mucosa cells].

Ethanol is one of the chemicals related to the development of oral malignant neoplasms. Micronuclei are chromatin fragments which, after aberrant mitoses, do not become included in the main nucleus. They have been used as indicators of genotoxic damage in cells exposed to carcinogens.
