Abstract

Objective: The objective was to evaluate cone-beam computed tomography (CBCT) indications and distribution in pediatric, adolescent and adult patients. Methods: A total of 1013 CBCT images were reviewed in detail from the electronic patient database. The patient’s age, gender, CBCT indications and acquisition sites, referral departments, reason for referral, incidental findings in the imaging field and the presence of artifacts in the CBCT images were all recorded. The European DIMITRA project recommendations were used to categorize CBCT indications in the children and the European Guidelines were used for adults. Results: From a total of 1013 images; 5.3% were from children, 9.2% were from adolescents and 85.5% from were adult patients. The most common indication was impacted permanent teeth in children (37%) and adolescents (34%) and impacted 3rd molars (28.7%) and implant dentistry (25.8%) in adults. While the most common regional image was taken from children (37%) and adolescents (43.4%), it was determined that CBCT was taken from the maxilla+mandible (37.7%) in adults. Conclusion: Our results show that while attention was paid to use CBCT in children and adolescents in accordance with clinical guidelines and taking into account radiation protection protocols, it was used in the adult patient group in cases where it is not superior to traditional methods.

Abstract

Objective: The aim of this study was to evaluate the position, angulation and surrounding trabecular bone structure of a unilateral impacted maxillary canine (IMC) tooth using fractal analysis. Methods: Cone beam computed tomography images of 50 patients (38 female, 12 male) with unilateral IMC were selected for this retrospective study. A 25x25 pixel region of interest (ROI) was selected in the trabecular bone between the premolars on the impacted and non-impacted side and fractal analysis was conducted. The angulation of unilateral impacted canines was measured and the position was categorized as vestibular, intra-alveolar and palatal. Results: Of the 50 impacted teeth, 42% were in the vestibular, 26% were in the intra-alveolar, and 32% were in the palatal position. The most common angulation angle of the IMC was 0°-15° which occurred in 44% of canines. While the bone fractal values did not statistically significantly differ between the sides, the values were 1.05 ± 0.9 on the impacted side and 1.04 ± 0.1 on the non-impacted side. No significant difference was observed in fractal values according to the position and angulation angles of the impacted maxillary canine (p > 0.05). Conclusion: The structure of trabeculation around the impacted canine tooth was no different than on the non-impacted side.
