Prevalence of Impacted Teeth in Saudi Patients Attending Dental Clinics in the Eastern Province of Saudi Arabia: A Radiographic Retrospective Study

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.

Severity and Treatment Difficulty of Impacted Maxillary Canine among Orthodontic Patients in Riyadh, Saudi Arabia

“…A thorough understanding of the severity of maxillary canine impaction and the anticipated treatment difficulty is expected to significantly benefit the diagnosis, selection of management strategies, and estimation of treatment costs and time. A few studies in Saudi Arabia have evaluated the severity of impaction and the difficulty of orthodontic therapy [ 1 , 2 , 19 ]. This study aimed to evaluate the severity of the impacted canine and the treatment difficulty index of maxillary canine impaction and their relation to gender, age group, and bucco-palatal position.…”

“…Maxillary canine impaction (IMC) is the most common type of impaction, following that of the third molars [ 1 , 2 ]. The prevalence of maxillary canine impaction is stated to range between 1% and 3% across varying populations [ 3 , 4 , 5 , 6 ].…”

Impacted Canines Classification Systems Among Orthodontic Patients

“…Permanent canine impaction may be caused by one or more of the following etiologies: (1) space deficiency in the dental arch, (2) disturbances in tooth eruption sequence, (3) trauma, (4) over-retained primary canine, 13 (5) premature root closure, (6) supernumerary teeth, (7) rotation of tooth buds ankylosis, (8) missing adjacent lateral incisor, (9) overlying cysts or tumors, (10) cleft lip or palate reconstructive surgery, (11) soft or bone tissue thickening. 28,29 The prevalence of impacted canine values varies significantly across ethnicities attributed to the genetic and ethnic variations [29][30][31][32][33] (Table 1). Considering location and gender, females are more likely than males to have permanent canine impaction.…”

Periodontal parameters in orthodontically tractioned teeth: A systematic review and meta-analysis

“… 18 Early detection of impacted teeth can help prevent the establishment of malocclusion, thus aiding occlusal and aesthetic functional gain. 19 Therefore, it is crucial to understand the behavior of the periodontal support structures of impacted teeth after orthodontic traction.…”
