Analysis of the reasons for requesting dental cone-beam computed tomography (CBCT) in children and adolescents can provide new evidence to guidelines developed specifically to protect patients from potential harmful effects of ionizing radiation. This retrospective study aimed to determine the reasons for requesting dental CBCT in paediatric patients. We included all patients aged <18 years who underwent CBCT between 2011 and 2021 at the Dentomaxillofacial Radiology Department of Dicle University Dental Faculty. Out of 8214 archived records in total, 1619 CBCT request forms of paediatric patients were examined. These forms provided the data on each participant’s age, gender, requesting department, the reason for the request, and year of the request. We evaluated 762 males and 857 females; 0.68% were aged 4–5 years, 27.55% were 6–11 years, and 71.77% were 12–17 years. The requests for CBCT were made by the Orthodontics Department in 61.4% of cases and by the Surgical Department in 25.82% of cases. The most common indication for CBCT (33.42% of cases) was to determine the presence of embedded teeth. We found a significant correlation between the age group and indications (p < 0.05). The age group of children and adolescents for whom CBCT was requested most often was the 12–17 years age group. In conclusion, the most common indication for CBCT was to determine the presence of embedded teeth in orthodontics. The rate of use of CBCT in the diagnosis and treatment of paediatric patients in dentistry has increased in the last decade.

Tooth decay, which is most common in childhood, especially in the 2-5 age group, is a health problem that should be addressed as a priority. It has been reported that the application of remineralizing agents to early stage caries reduces early material loss and stops the progression of caries. In studies conducted from the past to the present, various caries preventive agents have been investigated and utilized within the scope of preventive dentistry for the early diagnosis of caries and prevention of carious lesions.

Aim: This retrospective study aimed to evaluate the radiographic success of apexification treatments applied with different materials and techniques. Methodology: Periapical radiographs of 224 maxillary incisors in patients between 6 and 12 years of age who had undergone apexification treatment at the Dicle University, Faculty of Dentistry, Department of Pediatric Dentistry were retrospectively examined. Each apex was scored using the periapical index (PAI) on X-rays obtained at 12 months of follow-up after treatment, and the presence or absence of the apical barrier was evaluated. The Kruskal–Wallis H, Mann–Whitney U, and chi-square tests were used for the statistical analysis (p < 0.05). Results: In the maxillary incisors, apexification was most commonly performed on the maxillary right central teeth (74.11%). The cause for this treatment was trauma in 97.77% of the patients. Enlargement in the periodontal space (95.98%), the presence of lesions (60.71%), loss of lamina dura (54.46%), and external resorption (43.75%) were observed. At 12 months of follow-up after treatment, apical closure (87.95%) was observed in all teeth with open apexes, and the ratio of patients with a PAI of < 2 was 89.35% for calcium hydroxide (CH) apexification and 92.73% for mineral trioxide aggregate (MTA) apexification. Conclusion: The radiographic success of apexification treatments with CH and MTA was found to be high in 224 immature upper incisors.
