Efficacy of two dosages of dexamethasone administered by submucosal injection on postoperative sequelae after third molar surgery: A retrospective study.

Purpose: A retrospective clinical study was performed to compare the post-operative sequelae of the submucosal administration of two different low dosages of dexamethasone, after the surgical extraction of lower third molars.

Methods: Data regarding edema, trismus, pain and analgesic consumption were collected from 150 subjects, selecting three equal groups (n= 50): a control group with no administered dexamethasone (G1); submucosal injection of dexamethasone 2 mg/0.5 ml (G2) and submucosal injection of dexamethasone 4 mg/1 ml (G3).

Chairside CAD/CAM Materials: Current Trends of Clinical Uses.

Restorative materials are experiencing an extensive upgrade thanks to the use of chairside Computer-aided design/computer-assisted manufacturing (CAD/CAM) restorations. Therefore, due to the variety offered in the market, choosing the best material could be puzzling for the practitioner. The clinical outcome of the restoration is influenced mainly by the material and its handling than by the fabrication process (i.

Evaluating the stability of extended-pour alginate impression materials by using an optical scanning and digital method.

Statement Of Problem: The dimensional stability of alginate dental impressions is a key factor for the reliability of delayed gypsum pouring and digital scanning. However, studies of the dimensional stability of alginates with conventional methods that consider the dimensional variations of large impressions are lacking.

Purpose: The purpose of this in vitro study was to investigate and compare 2 digital methods for the analysis of dimensional stability of large impressions made with 5 different extended-pour alginates and to assess dimensional stability up to 5 days.

Efficacy of Alveolar Ridge Preservation after Maxillary Molar Extraction in Reducing Crestal Bone Resorption and Sinus Pneumatization: A Multicenter Prospective Case-Control Study.

Aim: To evaluate, with three-dimensional analysis, the effectiveness of alveolar ridge preservation (ARP) after maxillary molar extraction in reducing alveolar bone resorption and maxillary sinus pneumatization when compared to unassisted socket healing.

Methods: Patients were included in the study following inclusion criteria and underwent minimally traumatic maxillary molar extraction followed by ARP using synthetic nanohydroxyapatite (Fisiograft Bone, Ghimas, Italy) (test group) or unassisted socket healing (control group). Cone-beam computerized tomographies (CBCT) were performed immediately after tooth extraction (T0) and 6 months postoperatively (T1).
