Effect of chemical cleaning agents on the flexural strength of acrylic and hard denture line resins.

This study sought to evaluate the disinfectants, Efferdent (EF) and 0.5% sodium hypochlorite (SH), and their effects on the flexural strength and modulus of elasticity of the hard denture liners, Kooliner (K) and New Truliner (NT), and a thermoacrylic resin, QC-20. Ninety specimens were made (50 mm x 10 mm x 3 mm) and divided into 9 groups (n = 10).

Effect of double flasking and investing methods on artificial teeth movement in complete dentures processing.

Purpose: The aim of this study was to evaluate linear dimensional alterations of artificial teeth for complete dentures when using different investment and flasking techniques.

Background: Dimensional changes in the vertical dimension may occur owing to changes in artificial teeth positioning caused by different investing and flasking techniques.

Materials And Methods: Thirty pairs of the complete dentures were manufactured and randomly divided into three groups (n = 10): (1) invested with type III stone in monomaxillary PVC flask; (2) invested with type III stone in bimaxillary PVC flask; and (3) invested with laboratory silicone in bimaxillary PVC flask.

Genomics and the new perspectives for temporomandibular disorders.

The field of temporomandibular disorders (TMD) is experiencing significant changes in terms of aetiology and treatment. Researchers and clinicians are becoming increasingly aware of the possibility that genetic variations may play a role in pain perception and onset of TMD. In this review, we purpose to briefly describe these allelic variants, how they may be involved in TMD pathophysiology and how they may affect TMD treatment.

Is an elongated stylohyoid process prevalent in the elderly? A radiographic study in a Brazilian population.

Background: Elongation and calcification of the stylohyoid ligament complex may be correlated with Eagle's syndrome. The styloid complex pathogenesis is still being debated.

Objective: The aim of this study was to investigate the prevalence of stylohyoid ligament complex elongation in panoramic radiographs of 2252 patients in a Brazilian adult, partially edentulous population, of both sexes.
