A qualitative investigation of dental internships in Saudi Arabia: Exploring the experiences of dental interns.

Background: For dental graduates, internships are a vital transitional phase that gives them the invaluable opportunity to close the gap between their academic studies and the reality of professional dentistry. Research on dental internships remains limited and most of the existing studies focus on the clinical aspects of dental internships with little attention given to dental interns' experiences overall. This study aims to bridge this gap in the literature by gaining an in-depth understanding of Saudi dental graduates' range of experiences as dental interns.

Student feedback on team-based learning in a preclinical oral surgery course: A pilot study.

The present study evaluated the student's learning experience and satisfaction using a TBL method in a preclinical oral surgery course.

Methods: Twelve TBL sessions were designed for second-year dental students.

Cone-Beam Computed Tomography (CBCT)-Based Diagnosis of Dental Bone Defects.

Cone Beam Computed Tomography (CBCT) has completely changed the way that bone disorders are diagnosed and treated, especially in the dental and maxillofacial domains. This article examines the diverse applications of computed tomography (CBCT) in the diagnosis and treatment of facial trauma, including mandibular, dentoalveolar, and other facial fractures, as well as bone abnormalities like dislocations and fractures.
