Materials and methods: This study included CBCT images of 190 individuals (88 males and 102 females). The sagittal and transverse diameters and circumference of the FM were measured. The shape of FM was classified as round, hexagonal, oval, egg-shaped, tetragonal, pentagonal, irregular A, and irregular B. The data were statistically analyzed with chi-square and t-tests to assess the level of significance for sex and age. Results: The means of its sagittal and transverse diameters and also circumference were higher in males than in females. Statistically significant differences were found between males and females for all variables (P < 0.05). No statistically significant difference (P > 0.05) was found between age groups for all variables. The round type was the most common, in 21.6% of the patients. Conclusion: CBCT images can provide valuable information regarding FM and the measurements of its sagittal and transvers diameters and also its circumference may be reliably used for sexual dimorphism in anthropometric analysis and forensic medicine.

Konik ışınlı bilgisayarlı tomografi maksillofasiyal yapıların üç boyutlu radyografik değerlendirmesine olanak sağlayan bir görüntüleme yöntemidir. Son yıllarda, karmaşık endodontik problemlerin teşhisi ve tedavisi için üç boyutlu görüntülemeye başvurulmaktadır. Bu derlemenin amacı endodontik uygulamalarda konik ışınlı bilgisayarlı tomografinin kullanım amaçlarını ve sınırlamalarını araştırmaktır.

Methods: The study included 10 282 patients aged 15 and over who admitted to the Department of Oral and Maxillofacial Radiology, Faculty of Dentistry between September and December 2019, and whose medical history was digitally recorder. The age, gender, systemic disease status and medication use of each patient were recorded. Descriptive analysis of the obtained data was performed. Statistical differences according to age and gender were analyzed using by Pearson chi-square and Fisher's exact tests. Results: The anamnesis records of a total of 10 282 patients, 6015 (58.50%) female and 4267 (41.50%) male, were examined in this study, retrospectively. While 86.82% of the patients included in the study did not have any systemic disease, the number of patients with at least one systemic disease was 1355 (13.18%). Significant difference was determined between genders in terms of systemic disease incidence (p<0.05). Conclusion: Our study results showed that hypertension and diabetes are the most common systemic problems in patients who applied to the dental faculty for dental treatment. While hypertension, diabetes, asthma and goiter were more prevalent in females, chronic obstructive respiratuary system disease, cardiovascular operations and hyper/hypothyroidism were more prevalent in males.

In addition, the correlation between the pubertal growth spurt (PGS) and FD values was examined. Methods: The lateral cephalometric and hand-wrist radiographs of 120 subjects (61 females and 59 males) aged 8–18 years with a mean age of 13 years, were evaluated retrospectively. The CVM stages were determined in accordance with Hassel-Farman’s modification of Lamparski criteria. The HWM stages were determined in accordance with Björk and Grave-Brown criteria. Both HWM and CVM stages were divided into two according to PGS. Fractal analysis of cervical vertebrae was performed according to the White-Rudolph method. The relationships between HWM stages, CVM stages and other variables were evaluated by Spearman’s rank-order correlation coefficient. The relationships between FD values, chronological age, and divided stages were evaluated by the Pearson correlation coefficient. The Mann–Whitney U test was used to compare the FD values of two divided stages. Results: There were positive and statistically significant positive correlations between chronological age and both HWM and CVM stages. There was a positive and statistically significant correlation between CVM and HWM stages. In females and total, there were negative and statistically significant correlations between C4 FD values and divided HWM stages, and the differences between C4 FD values of divided HWM stages were also statistically significant. In total, there was a negative and statistically significant correlation between C4 FD values and divided CVM stages, and the difference between C4 FD values of divided CVM stages was also statistically significant. Conclusion: The negative correlations found between C4 FD values and divided HWM and CVM stages suggest the fractal analysis of cervical vertebrae, especially of C4, may be used as an objective tool for evaluating the PGS.

Füzyon ve geminasyon klinik görünüm olarak birbirine çok benzemekle birlikte oluşumları farklıdır. Füzyon iki ayrı diş germinin birleşmesi sonucu oluşur. Geminasyonda ise bir diş germinden iki diş oluşmaktadır. Nadiren görülen bu diş anomalileri hem daimî dişlerde hem de süt dişlerinde görülebilmektedir. Etiyolojileri tam olarak bilinmemektedir; dişlerin oluşum evrelerinde karşılaştıkları herhangi bir fiziksel kuvvet sonucu veya genetik yatkınlık nedeniyle oluştuğu düşünülmektedir. 1 Füzyon ve geminasyonun klinik muayene sırasında birbirinden ayırt etmek için ağız içindeki diş sayısına bakılmaktadır. Diş sayısında herhangi bir nedenle diş kaybı olmadan eksiklik

Objectives: The aim of this study was to analyze the accuracy and quality of information provided about MRONJ of YouTube videos. Material and methods: A systematic search was conducted on YouTube using two keywords, including MRONJ and bisphosphonate-related osteonecrosis of the jaw. A total of 80 videos were evaluated. Video information and quality index (VIQI) were used to evaluate overall quality of videos. Comparison of categorical variables was performed with c 2 and Fisher's exact tests. Correlation between characteristics of videos was analyzed using Kendall's tau-b correlation coefficient. Results: Most of the videos were found to be uploaded by doctors/dentists or maxillofacial surgeons (38.8%). The majority of videos were low-content videos. Most of high-content score videos were loaded by academic health institutions/professional organizations. Relationship between VIQI and usefulness (r = 0.801, p = 0.000) was found to be high. A positive correlation was observed between length of the video and interaction index (r = 0.226, p = 0.005). Conclusions: The majority of videos related to MRONJ contain videos with low-content/scores. Healthcare providers should be more engaged in providing accurate and reliable evidence-based information, and present their best practices information about MRONJ on YouTube.
