Prevalence of zygomatic air cell defects in a North American population.

Zygomatic air cell defects (ZACDs) are asymptomatic defects present in the zygomatic process and articular eminence of the temporal bone. This defect is considered a normal anatomical variant and can be detected on routine panoramic images. The objective of this study was to determine the prevalence, dominant type, and location of ZACDs in a North American population.

Investigating Dental Aptitude Test (DAT) results as predictors for preclinical and clinical scores in dental school.

Objective: The aim of the present study is to determine whether 2 current admission criteria, the perceptual ability test (PAT) and the manual dexterity test (MDT) can predict success in dental school within the Université de Montréal population.

Methods: A retrospective cohort study was conducted using the records of 854 students who graduated between 2005 and 2015. For each student, PAT and MDT scores were compared to 5 preclinical and 3 clinical classes using the Pearson correlation coefficient and regression models.

Influence of Experience and Training on Dental Students' Examination Performance Regarding Panoramic Images.

Physician training has greatly benefitted from insights gained in understanding the manner in which experts search medical images for abnormalities. The aims of this study were to compare the search patterns of 30 fourth-year dental students and 15 certified oral and maxillofacial radiologists (OMRs) over panoramic images and to determine the most robust variables for future studies involving image visualization. Eye tracking was used to capture the eye movement patterns of both subject groups when examining 20 panoramic images classified as normal or abnormal.
