    Investigating the Effects of Smoking on Trabecular Bone Structure Using Fractal Analysis: A Pilot Case-control Study
    (Galenos Publ House, 2023) Azman, Duygu; Tassoker, Melek
    Objective: Fractal analysis (FA) is a method that performs the evaluation of complex and irregular body structures through mathematics. The aim of this study is to use the FA approach to determine how smoking affects mandibular trabecular bone structure on panoramic radiographs. Methods: While 55 smokers constituted the study group, 55 nonsmokers constituted the control group. The study and control groups were paired for age and sex. Two region of interest (ROIs) with a pixel size of 100x100 were determined from the right mandibular angulus and the trabecular bone region between the right second premolar and first molar roots (interdental). Utilizing the box counting technique, FA was conducted on the ROIs identified by the panoramic radiography. SPSS 21.0, developed by IBM Corp in Armonk, NY, USA, was used for the data analysis. At the 0.05 threshold, p-value was regarded as significant. Results: The mean age of 74 male and 36 female individuals included in the study was 23.54 & PLUSMN;3.57 years. Fractal dimension (FD) values of gonial (p=0.528) and interdental regions (p=0.490) did not differ statistically from each other between the study-control groups (p>0.05). When the correlation analysis of pack-year values of smoking exposure and FD measurements was performed, a negative correlation that was not statistically significant was found (p>0.05). Conclusion: As cigarette exposure increases, FD values tend to decrease. No effect of smoking on mandibular trabecular bone FD values was observed.

    Morphometric Analysis of the Foramen Palatinum Majus by Cone-beam Computed Tomography
    (Galenos Publ House, 2023) Tassoker, Melek; Azman, Duygu; Aydin Kabakci, Anil Didem
    Objective: The aim of this study was to detect possible variations of the foramen palatinum majus (FPM), by imaging with cone-beam computed tomography (CBCT), and to make a morphometric comparison of FPM in dentate and edentulous individuals. Methods: In the study, CBCT recordings of 250 individuals, 125 dentate and 125 edentulous individuals, in the archive of the Faculty of Dentistry, Oral and Maxillofacial Radiology were retrospectively analyzed. The diameter of the FPM, its position relative to the molar teeth, its shape (round, ovoid, slit), its distance from the midmaxillary suture (MMS), and its distance from the incisive foramen NY, USA) was used for the analysis of the data and it was considered significant at the p<0.05 level. Results: The records of 122 female and 128 male patients aged between 18 and 86 years (52 +/- 16) were examined. In dentate individuals, FPM was most frequently located in the region between the second and third molars, 54.4% on the right and 56.8% on the left. The most common FPM shape was ovoid, with 80% on the right and 74.4% on the left. The diameter of FPM, FPM-MMS, and FPM-IF distance showed a statistically significant difference between dentate and edentulous individuals, and the values of edentulous individuals were higher (p<0.05). procedures in this region.
