Prevalence of periapical radiolucent lesions in endodontically-treated teeth with intraradicular posts: a cross-sectional CBCT study.

Background: The literature has reported contradictory findings regarding the association of Intra-radicular posts (IRPs) presence and periapical radiolucent lesions (PRLs) prevalence in endodontically treated teeth (ETT). Considering this, the study aimed to investigate the association between IRPs presence and PRLs prevalence.

Methods: A cross-sectional study was conducted to compare PRLs prevalence in ETT with and without IRPs.

Prevalence of palatogingival groove affecting maxillary anterior teeth in Saudi subpopulation: A cone-beam computed tomographic study with literature review.

Aim: To investigate the prevalence of palatogingival groove (PGG) affecting maxillary anterior teeth, bilateral occurrence, and distribution among sex in the Saudi subpopulation and to review the literature on the prevalence of PGG.

Introduction: Palatogingival groove (PGG) primarily affects maxillary lateral incisors and, when present, may contribute to the pathogenesis of periodontal and endodontic lesions.

Materials & Methods: A total of 509 CBCT scans of Saudi patients with 2747 maxillary anterior teeth were included in the study.

Photo-induced photoacoustic streaming and pineapple peel extract as final irrigant on extrusion bond strength of root filling material to canal wall.

Objective: Photon-induced photoacoustic streaming (PIPS) with pineapple peel extract (PPE) and ethylenediaminetetraacetic acid (EDTA) as a final endodontic irrigant on the push-out bond strength (PBS) of root filling material to conventional irrigation NaOCl with EDTA

Methods: An in vitro study at Dar Al Uloom University was conducted over three months. Root canal preparation was performed. Based on final irrigation, all the specimens were divided randomly into four groups (n=10) Group 1: 2.

Problem-based learning: Dental student's perception of their education environments at Qassim University.

Aims: The objectives of this study were to assess perceptions of the Saudi dental students of the problem-based learning (PBL) curriculum and to compare their perceptions among different sex and academic years.

Subjects And Methods: Data was collected through a questionnaire-based survey at Qassim College of dentistry. The questionnaire consisted of 19 questions regarding the perception of PBL curriculum and was distributed to 240 students.
