The aim of this study was to evaluated the masseter, anterior digastric and geniohyoid muscles of individuals with similar growth and developmental periods but different sagittal skeletal malocclusions using ultrasonography and ultrasonographic elastography and to make interclass assessments. In this study, ultrasonography and ultrasonographic elastography records of 30 Class I individuals (17 females, 13 males), 30 Class II individuals (14 females, 16 males), and 27 Class III individuals (12 females, 15 males) in the normodivergent and growth development period were used. The masseter, anterior digastric, and geniohyoid muscles of individuals were examined using ultrasonography and ultrasonographic elastography, and comparisons were made between the classes. Statistical analysis was accomplished by Mann Whitney U, One-way ANOVA, Kruskal Wallis H tests. Interclass differences were found in ultrasonography and elastography measurements of the masseter muscle. However, no differences were observed in ultrasonography measurements of the auxiliary masticatory muscles, whereas differences were seen only in the geniohyoid muscle in elastography measurements among the classes (p < 0.05). Individuals with different sagittal skeletal malocclusions during growth and development exhibited similar muscle sizes and elasticities, approximately close to each other.

Objective The objective of this study is to explore the prevalence, size, location and radiographic features of osteomas in the paranasal sinuses using cone beam computed tomography imaging. Study design This study was planned as retrospective cross-sectional. 499 consecutive cone beam computed tomography scans obtained in a dentomaxillofacial radiology department for various dental indications. Statistical analysis of all data was done with SPSS version 22. Descriptive statistics and chi-square tests were used to determine the prevalence of categorical parameters. Results Osteoma was detected in 7 % (n = 35) of the 499 images analyzed. The age of the patients ranged from 6 to 96 years (mean 42.03 ± 18.70). No significant difference was found between the genders (p = 0.77). In terms of localization, it was significantly more common in the ethmoid sinuses (p < 0.01). Cortical type osteoma was observed the most frequently in the analyzed images (p < 0.01). The incidence of osteoma was not significant depending on age (p = 0.50). Conclusion Osteomas in the paranasal sinuses show a 7 % prevalence in CBCT images, with the ethmoid sinus being the most common site. The average size of osteomas was 3.43 ± 1.78 mm, predominantly cortical in type. These findings highlight the necessity for thorough examination of CBCT images by dentomaxillofacial radiologists to avoid overlooking osteomas.

Objective: This study aimed to evaluate the relationship between the presence of calcium deposits (CDs) around the dens axis and patients' age, gender, and systemic diseases. Methods: This retrospective study was carried out by examining CBCT. Basic descriptive statistical analyses and normality tests were performed on all variables. The assumption of normality was checked using the Shapiro-Wilk method. The statistical significance level was accepted as a p-value less than 0.05. Results: CDs were observed in a total of 99 (21.9%) individuals. The incidence of CDs statistically significantly increased with age (p < .01),while it didn't statistically significantly differ between genders (p = .47). 13% were systemically healthy, while 55% had hypertension. The incidence of CDs was statistically significantly higher in individuals with hypertension. Conclusions: In the presence of CDs, the patient should be referred to a medical doctor to confirm the diagnosis of CDS and prevent possible complications.

Introduction: Due to the silent manifestation of temporomandibular joint (TMJ), dentists and rheumatologists may neglect treatment for this joint. Aims: The aim of this study was to investigate the TMJ components in patients with various rheumatic diseases and to compare them with a control group based on cone beam computed tomography (CBCT) images. Materials and Methods: This study comprised an assessment of the CBCT images of 65 patients (130 temporomandibular joints) with various rheumatic diseases (mostly rheumatoid arthritis) affecting the TMJ. Moreover, 65 patients (130 temporomandibular joints) with a similar age and gender distribution were examined as the control group. Pathologies were classified into a total of 12 types for the presence of any osseous changes in the condylar head or articular fossa or for joint space narrowing. Statistical analysis of all data was performed with SPSS version 18. The conformity of continuous variables to a normal distribution was examined by the Kolmogorov–Smirnov test. The Mann–Whitney U test was used to compare the means of two independent groups. The Pearson Chi-square test, Yates correction and Fisher’s exact test were used in the analysis of categorical variables. Results: The mean age of the patient and control groups was 50 ± 13 and 48 ± 16, respectively, and no statistically significant difference was found between the patient and control groups in terms of age distribution (p = 0.123). Condylar erosion, condylar flattening, subcondylar sclerosis, osteophytes, subcortical cysts, articular eminence resorption and articular eminence flattening rates were found to be statistically significantly higher in the patient group than in the control group (p < 0.05). Conclusions: Dentomaxillofacial radiologists should examine the bony components of the TMJ in patients with rheumatic diseases, and a multidisciplinary approach involving a dental specialist and rheumatologist is required.

ABSTRACT Objective: This study aims to evaluate the prevalence of impacted 3rd molar, angulation status, the level of eruption, relationship with the occlusal plane of the 3rd molar teeth, and the rate of pathology in their own and the adjacent tooth of Turkish adult individuals who applied to Akdeniz University Faculty of Dentistry via panoramic radiographic images. Material and Methods: 700 patients were examined for this retrospective study. In addition to the localization, eruption, angulation, and occlusal level of the 3rd molars, the accompanying pathologies and the pathologies in the adjacent 2nd molars were recorded and retromolar spaces were measured. p-value of <0.05 was considered statistically significant. Results: The rate of impaction in a total of 2800 3rd molars was 29%. Impacted 3rd molars were found at a higher rate(54.4%) in the mandible. It was determined that the 3rd molar teeth were mostly in the vertical position (77.8%) and 63.1% of them were at level A. 49.9% of mandibular third molar teeth were in class I. Conclusion: Impacted 3rd molar teeth prevalence was 29 %. The most common angulation status was vertical. According to the level of impaction, it was determined that the occlusal planes of the 3rd molars and the 2nd molars were at the same level most frequently. The location of the 3rd molar completely in front of the anterior ramus was the most common position. The most common pathology in the 3rd molars was caries, and no pathology was found in the 2nd molars except caries.Keywords: Impacted teeth; panoramic radiography;third molarsÖZET Amaç: Bu çalışmada, Akdeniz Üniversitesi Diş Hekimliği Fa-kültesine başvuran Türk erişkin bireylerin gömülü 3. büyük az ı diş-lerinin prevalans ı, açılanma durumu, sürme düzeyi, 3. büyük az ıdişlerinin okluzal düzlemi ile ilişkisi ve kendi ve komşu dişteki patolojioranlarının panoramik radyografik görüntüler ile de ğerlendirilmesiamaçlanmıştır.

The aim of this study was to compare the accuracy of the Willems method, Nolla method, Cameriere dental age estimation method(CDM), Greulich-Pyle Atlas(GPA) method, and Cameriere bone age estimation method(CBM) for age estimation in healthy children aged between ten and 14.9 years, according to the pubertal growth stage(PGS). The accuracy was determined as the difference between estimated age(EA) and chronological age(CA) was assessed by analysing orthopantomograms and hand-wrist radiographs. At the onset of the PGS, the Willems method showed the closest value to the CA for both sexes(girls = 0.17 ± 0.78, boys = 0.006 ± 0.96 years). At the peak, the Willems method showed the closest value to the CA for girls(0.005 ± 1.09 years), and the GPA method for boys(0.05 ± 0.68 years). At the end of the PGS, the Willems method showed the closest value to the CA for girls(0.09 ± 1.23 years), and the CBM for boys(0.24 ± 0.74 years). It was observed that all methods concluded with the closest result to the CA at the onset period of the PGS. Our study demonstrates that sex and PGS are effective in over- or under- estimations that are obtained according to the CA.
