Submandibular gland excision.

Objective: to analyze the value of fine needle aspiration and the rates of postoperative complications in patients undergoing resection of the submandibular gland.

Methods: we analyzed the records of patients treated with resection of the gland from January 1995 to December 2008. The data collected included age, gender, findings on clinical history, surgical procedure, results of fine needle aspiration (FNA), pathological diagnosis and complications.

Photodynamic therapy reduces bone resorption and decreases inflammatory response in an experimental rat periodontal disease model.

Objective: The purpose of the present study was to analyze inflammatory conditions after application of photodynamic therapy (PDT) in the gingival tissues of Wistar rats with ligature-induced periodontal disease.

Background Data: The work investigated the effectiveness of PDT in decreasing the inflammatory response, in order to avoid bone loss.

Methods: Ligatures were positioned at the mandibular first molar of rats (n=6).
