Erbium Yttrium-Aluminum-Garnet Laser Versus Traditional Bur in the Extraction of Impacted Mandibular Third Molars: Analysis of Intra- and Postoperative Differences.

Introduction: Different osteotomy techniques have been proposed in order to improve postoperative course of impacted third molar extraction. The aim is to evaluate the possible advantages achieved with erbium yttrium-aluminum-garnet (Er:YAG) laser osteotomy compared with traditional burs.

Materials And Methods: Seventy-six extractions were randomly classified into 2 groups according to osteotomy instrument: group 1 (G1)-Er:YAG laser: 35 patients; group 2 (G2)-traditional bur: 41 patients.

Medication-related osteonecrosis of the jaw: risk factors in patients under biphosphonate versus patients under antiresorptive-antiangiogenic drugs.

Background: Biphosphonate-related osteonecrosis of the jaw (BRONJ) is a potential side effect associated with the administration of bisphosphonates; the aim of this work is to highlight the possible epidemiological differences between two groups of patients affected by medication related osteonecrosis of the jaw (MRONJ) treated at the Center of Oral Medicine, Pathology and Laser Surgery of the Academic Hospital at the University of Parma, Italy, between January 2004 and June 2016.

Methods: Medical charts of 303 patients (214 females and 89 males, mean age: 67 years old) treated at the Center of Oral Medicine, Pathology and Laser Surgery of the Academic Hospital at the University of Parma, between January 2004 and June 2016, were retrospectively analyzed. Patients were divided in 2 groups according to drugs therapy they underwent: group 1 (G1) including patients treated with bisphosphonates alone and group 2 (G2) including patients receiving antiresorptive-antiangiogenic drugs in association with bisphosphonates or antiresorptive-antiangiogenic drugs alone.
