Evidence for reduced torsional resistance of rotary files under curved position.

Objectives: The aim of this in vitro study was to investigate the torsional fatigue resistance of different rotary files in straight and curved positions at a simulated intracanal temperature.

Methods: Forty-eight size #25 files from ProTaper Universal (PTU), ProTaper Next (PTN) and ProTaper Gold (PTG) were tested for torsional resistance in both straight and curved (90 degrees) positions (n = 8 each). The experiment was conducted at a simulated intracanal temperature of 35 ± 1 °C.

Oral Health-related Quality of Life and Oral Hygiene Practice of Adults with Fixed Dental Prostheses in Riyadh, Saudi Arabia.

Objectives: Missing teeth are routinely replaced with fixed dental prostheses (FDPs); thus, knowing the patient's oral health-related quality of life (OHRQoL) after placement of FDP and factors affecting their quality of life in addition to their oral hygiene practices is important. This study aimed to measure OHRQoL with FDPs and oral hygiene practices of adults in Riyadh, Saudi Arabia.

Materials And Methods: A survey was distributed in hard and soft copy forms.

Dental esthetic and the likelihood of finding a job in Saudi Arabia. A cross-sectional study.

Background: Person's physical, dental appearance, and sexual identity are the characteristics most obvious to others. Prior researches suggest that visible sign of unhealthy dental status may lead to an individual's social or professional exclusion, so the aim of the study was to measure the influence of dental appearance on hiring managers' perception of intelligence, honesty and efficiency of job applicants in Saudi Arabia, and the likelihood of employment opportunity.

Materials And Methods: This cross-sectional study comprised 280 hiring managers.
