A comprehensive investigation into the prevalence of dental anomalies across Saudi Arabia, a systematic review

Dental anomalies may lead to problems with tooth alignment, function, and esthetic appearance of the teeth. Therefore, the objective of the present systematic study was to assemble national reference data about the prevalence of different dental abnormalities in Saudi Arabia. Systematic screening was initiated to identify studies in the following databases: Medline (PubMed, Ovid), Web of Science Core Collection, Google Scholar, and Scopus. Original research of Saudi Arabian healthy cases without medical problems at any age were included. The search only included studies written in the English language, from inception until end of September 2025 and studies should at least one tooth was affected exclusion the 3rd molars. The quality and the risk of bias of the included studies were evaluated using the Joanna Briggs Institute’s appraisal tool. The data about the prevalence dental anomalies were extracted and pooled. Out of 725 identified titles, 35 studies were finally included. The highest frequency of impacted premolars (8.33%) was found in the Central region. ectopic eruption (58.2%) and tooth rotation (54.4%) were the most prevalent anomalies in the Northern region. Tooth transposition mostly affected the Southern region (10.88%). Agenesis (7.61%) was the most common abnormality in the Western area. Dilaceration was the most prevalent in the Eastern area (21.01%). Dental anomalies can cause aesthetic and functional problems, meaning that early detection, prevention, and treatment approaches are critical in minimizing their impacts.
