Multifactorial analysis of the maxillary premolar area for immediate implant placement using cone beam computed tomography: A study of 333 maxillary images.

Statement Of Problem: Immediate implant placement in the maxillary premolar area is challenged by anatomic variations imposing risks such as perforation of the buccal bone and the maxillary sinus. Previous studies have addressed the potentially relevant factors individually; a study assessing all relevant variables comprehensively and with a large sample size is lacking.

Purpose: The purpose of this observational study was to analyze multiple anatomic considerations, including sagittal root position, alveolar bone concavity angle, buccal bone perforation, maxillary sinus floor root proximity, and maxillary sinus perforation in the maxillary premolar area, using cone beam computed tomography (CBCT) to inform, perceive, and simplify the placement of immediate implants.

Prevalence of periodontitis in Saudi Arabia: A systematic review and meta-analysis.

Objective: The aim of this systematic review was to assess the prevalence of periodontal disease among Saudi Arabian adults based on studies conducted from 1992 to 2023.

Methods: The study protocol was registered in PROSPERO. Three databases (MEDLINE, EMBASE and Cochrane library) and the Saudi Dental Journal were searched for published literature up to June 2023 using prespecified search strategy.
