Prevalence and distribution of dental anomalies in Hail Province of Saudi Arabia

This study aimed to determine the frequency of dental anomalies and evaluate any possible factors that could contribute to them in a Saudi subpopulation. The study utilized clinical records and panoramic radiographs obtained from the College Dentistry Polyclinics at the University of Hail and a private practice in Hail City, Saudi Arabia. An assessment was conducted on various developmental abnormalities. The relationship between the research variables was determined using the Chi-squared test. The significance threshold was set at 0.05. The dental anomaly was found in 405 (66.9%). The distribution by gender was184 (30.4%) males and 221 (36.5%). Females. The prevalence of dental anomalies was higher in the age group of 9–25 years 278 (46.0%) compared to the age group of >25–55 years 127 (21.0%). Ectopic eruption was shown to be the most common dental anomaly (20.3%) followed by rotation (19.0%), impaction (14.9%), and retained deciduous tooth (14.1%). Multivariate regression analysis showed no significant association between gender and the prevalence of dental anomalies (OR = 0.925, p = 0.929). However, age was a significant predictor, with increasing age associated with a substantial reduction in the odds of dental anomalies (OR = 0.381, p < 0.0001). The prevalence of dental anomalies in the present investigation was notably high. No correlation was observed between the prevalence of dental abnormalities and gender. Dental anomalies were more commonly found in individuals aged 9–25 years compared to those aged >25–55 years.
