Retention of different all ceramic endocrown materials cemented with two different adhesive techniques.

Objective: The purpose of this in vitro study was to evaluate the influence of two adhesive techniques on the retentive force of four all ceramic endocrowns.

Materials And Methods: Forty maxillary first molars of approximately similar size and shape were collected. The teeth were all decoronated 2 mm above the level of proximal cement-enamel junction (CEJ) and were all endodontically treated.

Marginal gap distance and cyclic fatigue loading for different all-ceramic endocrowns.

Objective: The aim of the study was to evaluate the effect of the fabrication techniques of two types of glass ceramics on the marginal gap distance and the fracture resistance of endocrown restorations after cyclic loading.

Materials And Methods: Forty extracted mandibular first molars were root canal treated. Decoronation was done for all the endodontically treated teeth 2 mm above the cemento-enamel junction.

Physiotherapy Maneuver Is Critical to Recover Mouth Opening After Pediatric Trauma.

Purpose: A restricted mouth opening (MO) is predominantly a complication of maxillofacial trauma in pediatric patients and develops in 4 to 26.2% of cases. The purpose of the present study was to quantitatively investigate the influence of patient demographic data, fracture characteristics, and regular vigorous physiotherapy, with either voluntary or forcible MO exercises, on the recovery of a post-traumatic restricted MO in pediatric patients.

Laser and radiofrequency-induced hyperthermia treatment via gold-coated magnetic nanocomposites.

Introduction: The current radiofrequency ablation technique requires invasive needle placement. On the other hand, most of the common photothermal therapeutic methods are limited by lack of accuracy of targeting. Gold and magnetic nanoparticles offer the potential to heat tumor tissue selectively at the cellular level by noninvasive interaction with laser and radiofrequency.

Evaluation of neoplastic nature of keratocystic odontogenic tumor versus ameloblastoma.

Objective: Although most of odontogenic tumors are benign, some of them will show locally destructive behavior, as keratocystic odontogenic tumor (KCOT) is now known as a benign but aggressive odontogenic neoplasm. The neoplastic characteristics in KCOT have been suggested from clinical as well as pathologic aspects. Matrix metalloproteinase-2 (MMP-2) is a gelatinase form of the MMPs family, which is a group of proteolytic enzymes that degrade many types of collagen.
