Effect of artificial aging on the translucency of monolithic zirconia materials sintered at different temperatures.

Statement Of Problem: Translucent zirconia materials were developed as an alternative to lithium disilicate materials. However, the effect of sintering temperature and artificial aging on the translucency of zirconia materials is unclear.

Purpose: The purpose of this in vitro study was to investigate the translucency of recently developed zirconia materials after different sintering temperatures and the effect of artificial aging.

The Effect of Radiotherapy on the Marginal Adaptation of Class II Direct Resin Composite Restorations: A Micro-computed Tomography Analysis.

This laboratory study was designed to evaluate the marginal adaptation of Class II mesio-occlusodistal (MOD) restorations at the cervical region with micro-computed tomography (micro-CT). Two groups of restorations were compared: 1) those that had been exposed to radiotherapy before restoration was performed using a universal adhesive in etch-and-rinse and self-etch modes; and 2) those that had previously been restored using a universal adhesive in etch-and-rinse and self-etch modes and had subsequently undergone radiotherapy. Sixty intact human molars were randomly divided into groups according to irradiation status: no radiotherapy (control group); radiotherapy followed by restoration (radiotherapy-first group); and restoration followed by radiotherapy (restoration-first group).

Clinical Survival of Indirect, Anterior Surface-Retained Fiber-Reinforced Composite Fixed Dental Prosthesis: Up to 3-Year Follow-up.

This study evaluated the performance of indirect, anterior, surface-retained, fiber-reinforced-composite restorations (ISFRCR). Between September-2011 and September-2012, 17 patients (13 females, 4 males, mean age: 40.5) received 17 indirect ISFRCRs (maxilla=4; mandible=13).

Alternative technique to transfer jaw relations for custom mandibular advancement devices: A case report.

Oral appliance therapy for obstructive sleep apnea can be helpful in mild and moderate cases. This clinical report evaluates the efficacy of a protocol that predicts an optimal jaw position and describes the response of a young OSA patient to treatment. A 27-year-old woman was diagnosed with moderate OSA and had an apnea-hypopnea index (AHI) of 25.
