Abstract

Aim: To evaluate the prevalence of impacted teeth in Saudi patients and compare between male and female subjects.

Method: This cross-sectional study comprised of Saudi patients who attended dental clinics in major hospitals in the Eastern Province of Saudi Arabia. Patients' dental records and panoramic radiographs were reviewed retrospectively. Impacted teeth excluding third molars and spaces occupied by primary, permanent, and transmigrated teeth were recorded from panoramic radiographs. The Pearson chi-squared test was performed to determine gender differences regarding impacted teeth and spaces occupied by other teeth.

Results: The study included radiographs of 539 patients with a mean age of 23.3 ± 10.8 years. Seventy-one patients (13.2%) had at least one impacted tooth. The total number of impacted teeth was 115 in the sample, out of which 91 (79.1%) were in the upper arch and 24 (20.8%) in the lower arch. Fifty-eight maxillary canines (50.4%) were impacted making them the most commonly impacted teeth, followed by 21 upper second premolars (18.2%) and 14 lower second premolars (12.2%). More females (70.7%) than males (29.3%) had impacted teeth (P=0.82). Of 61 spaces occupied, 35 (57.4%) were occupied by permanent teeth, 24 (39.3%) by primary teeth, and 2 (3.3%) by transmigrated teeth. Greater proportions of spaces were occupied in female than male participants (P > 0.05).

Conclusion: There was a high prevalence of impacted teeth in Saudi patients. The canines were the most commonly impacted teeth followed by the second premolars. Females demonstrated a higher occurrence of impacted teeth than males. Early detection of impacted teeth can help prevent malocclusion and maintain a healthy dentition.
