Objectives: Odontogenic cysts, originating from inflammatory or developmental processes of the tooth germ epithelium, represent the most common intraosseous pathology in the head and neck region. This retrospective study aimed to evaluate bone healing following the surgical removal of odontogenic cysts using fractal analysis. Materials and Methods: Bone changes in 17 patients who underwent cyst enucleation were assessed using fractal dimension and lacunarity measurements on digital panoramic radiographs obtained before and six months after surgery. Statistical analyses included the Shapiro–Wilk test, paired t-test, Wilcoxon signed-rank test, repeated measures ANOVA, and the Friedman test. Results: At six months postoperatively, bone structure differences had largely normalized. In the cyst center, there were no statistically significant differences in fractal dimension or lacunarity (P > 0.05). At the cyst edge, fractal dimension remained statistically unchanged (P = 0.446), while lacunarity significantly decreased from 0.06 to 0.04 (P = 0.04). In unaffected control regions, no significant changes were observed (P > 0.05). Preoperative fractal dimension values significantly differed between regions (P < 0.001), but these differences were no longer significant postoperatively (P = 0.077). Lacunarity values showed no significant regional differences at either time point (P > 0.05). Conclusions: Fractal analysis offers valuable insights into bone regeneration and may surpass traditional radiographic evaluations. Despite limitations such as small sample size and potential subjectivity in region of interest (ROI) selection, the results support the utility of fractal dimension and lacunarity in tracking bone healing after cyst surgery.

Third molars are crucial in forensic age estimation during adolescence due to their late and variable development. The modified Demirjian method employs a nine-stage classification (0-H) for assessing dental maturity. However, population-specific validation is essential for forensic accuracy. This study aims to evaluate the relationship between chronological age and M3 development stages in a Turkish population using panoramic radiographs, and to investigate the influence of gender and anatomical location, including impaction classifications (Pell-Gregory and Winter). A total of 1656 individuals (mean age: 13.9±3.78 years) underwent digital panoramic radiography. Developmental stages of 2770 mandibular and 2553 maxillary M3s were assessed using the modified Demirjian method. Statistical analyses included Spearman correlation, Kruskal-Wallis tests and generalized linear models. Third molar development strongly correlated with chronological age. Most teeth were in stages B-E, with mandibular M3s most frequent in stages C and E, and maxillary in C and D. Age differed significantly across all stages (p<0.001). Generalized linear models confirmed age as a significant predictor (R²=0.330 mandible; R²=0.337 maxilla). Gender and impaction classifications had no main effects, but significant interactions were found (Pell-Gregory×Gender: p<0.001; Winter×Pell-Gregory: p=0.016). Conclusions: The modified Demirjian method reliably estimates age in Turkish adolescents, with high age-stage correlation. While gender and anatomical location alone do not alter developmental progression, their interaction with impaction patterns reveals complex growth dynamics. These findings support context-sensitive forensic protocols.

Objectives: The aim of the study is to assess the relation of Demirjian’s and Nolla’s dental age determination methods with chronological age and bone age in Turkish children aged between 10-15. Methods: In the retrospective study, 717 children were included, their chronological age and bone age in accordance with Greulich-Pyle Atlas by evaluating left hand wrist radiograms, dental age in accordance with Demirjian’s and Nolla’s methods by using panoramic radiograms were analyzed. Statistical analyses were performed using SPSS version 23.0 for Windows (SPSS Inc., Chicago, Illinois, USA). Results: The bone age and the dental ages calculated according to Demirjian’s and Nolla’s methods was found higher than the chronological age by +0.29 year, +0.77 year and +0.23 year, respectively. The closest result to chronological age came from Nolla’s method. Conclusions: In contrast to the previous studies in the South Turkish population, Demirjian method was found to give incompatible results. In this study, it was shown that Nolla method is more reliable in determining dental age for this population. In addition, the bone age and dental age estimated according to Nolla methods were quite similar to each other.

Purpose This study aims to assess the presence of accessory canal (AC) associated with canalis sinuous (CS), describing their frequency, lateralization, location, direction and measurements in cone beam computed tomography (CBCT). Methods Axial, coronal, sagittal, and cross-sectional reconstructions were analyzed in 248 CBCT images and the presence of CS, the presence of AC associated with CS, the lateralization, localization and direction course of AC associated with CS was evaluated. CS diameter, AC diameter, distance between nasal cavity floor and CS (M1), CS and the buccal cortical bone (M2) and CS and the alveolar ridge (M3) was measured. Results CS dedected in all CBCT scans as bilaterally. The prevalence of AC associated with CS was 35.5%. There was a significant difference between dental status and presence of AC associated with CS. There was a significant difference between gender, dental status, and lateralization of AC associated with CS. While M1 was greater in male patients than females, M3 was greater in female patients. M2 and M3 was greater in younger patients. Conclusion Clinicians performing surgical procedures should keep in mind that anatomical variations of the vascular nerve bundle may be seen. M1, M2, and M3 measurements can be affected by gender, age, and dental status.

Objective: Anamnesis, extraoral intraoral examination, radiographic examination, and other special examination methods are used to diagnose diseases in the oral and maxillofacial regions. The aim of this study was to establish the demographic, systemic, and radiographic characteristics of the patients by analyzing the records of patients who were treated at the Oral and Maxillofacial Radiology Clinic of the University Faculty of Dentistry. Methods: The anamnesis and diagnostic records of patients who were treated at the OMR clinic between 01.01.2013 and 31.12.2019 and the radiographic records of the patients referred to the X-ray department were retrospectively analyzed. The number of patients was analyzed according to demographic, systemic, and radiographic classifications, and tables were created according to years and total numbers. Results: The number of females who applied between 2013-2019 was statistically significantly higher than that of males. When the age distribution of all patients who applied to the OMR clinic was analyzed, it was observed that the patients who applied were 15 years of age and older, and 29.3% of these patients were in the 30-44 age group, with the highest proportion. When radiographic data were analyzed, it was observed that the most common radiograph obtained was a panoramic radiograph (90%). Conclusion: Anamnesis records revealed the systemic disease characteristics of the study area, which is helpful for diagnosis and treatment planning. The most requested radiographic types and clinics that requested the most radiographs were determined. This will help improve the functioning within and between departments. By determining the common diagnoses in panoramic radiographs, the issues to be considered in patients of certain age and sex groups have been clarified.
