Are Maxillary and Sphenoid Sinus Volumes Predictors of Gender and Age? a Cone Beam Computed Tomography Study
(Cumhuriyet University Faculty of Dentistry, 2020) Koç, A.
Objectives: This study aimed to analyze the applicability of maxillary ©*Alaettin Koçi sinus (MS) and sphenoid sinus (SS) volumes in determining gender and age. Materials and Methods: This retrospective study included cone beam computed tomography images of 164 MSs and 164 SSs of 82 patients (40 females and 42 males). Right, left, and total MS and SS volumes were estimated. The independent samples t-test, logistic regression, and Pearson correlation coefficient were used to explore their accuracy in determining age and gender.Results: Males had greater right SS, average, and total SS volumes than females (p=0.007, p=0.013, and p=0.013, respectively). The right SS volume had the best predictive power (65.9%) for gender. A regression formula using this parameter alone showed satisfactory accuracy. No significant correlations were found between age and MS or SS volumes (p>0.05). Conclusions: The SS volume is a valuable tool in determining gender, whereas neither MS nor SS are reliable predictors of age. A simple gender determination is possible with our regression formula using the right SS volume. Further studies are needed to investigate the role of paranasal sinus volumes with a view to develop formulations in determining age and gender in different populations. © 2020. All rights reserved.
Assessment of Buccal Bone Thickness in the Anterior Maxilla: a Cone Beam Computed Tomography Study
(Cumhuriyet University Faculty of Dentistry, 2019) Koç, A.; Kavut, I.; Uğur, M.
Objectives: The aim of this study was to evaluate buccal bone thickness by cone beam computed tomography (CBCT) in patients in both genders and in different age groups. Materials and Methods: Our study included 186 anterior teeth and 62 patients with CBCT images. Buccal bone thickness was measured at the crest level, and at a distance 1 and 2 mm apical to the crest level. The t-test and ANOVA test were used in analyzing data. Results: It was found out that age and gender were not significantly associated with the buccal bone thickness of anterior teeth (p > 0.05). The mean buccal bone thickness was the highest as 1.91 mm around the right canines and it was the lowest as 0.35 mm surrounding the right lateral incisor. Conclusions: Our study demonstrated that the mean buccal bone thickness increased towards the apical region for all three teeth types. CBCT precisely measures the maxillary bone thickness and may facilitate the planning process for placing implants and scheduling other types of surgeries correctly. © 2019 Cumhuriyet University Faculty of Dentistry.; Amaçlar: Farkli yaş gruplarindaki ve cinsiyetteki hastalarin bukkal kemik kalinliklarinin konik işinli bilgisayarli tomografi (KIBT) kullanilarak değerlendirilmesi amaçlanmiştir. Gereç ve Yöntemler: çalişmamiza anterior 186 diş ve 62 hastanin KIBT görüntüleri dahil edilmiştir. Kret seviyesindeki, kret seviyesinden 1 ve 2 mm apikaldeki bukkal kemik kalinliklari ölçülmüştür. Elde edilen veriler T testi ve One-way ANOVA testi kullanilarak analiz edilmiştir. Bulgular: Anterior dişlerdeki bukkal kemik kalinliğina yaş gruplari ve cinsiyetin anlamli bir etkisinin olmadiği anlaşilmiştir (p > 0,05). En yüksek ortalama bukkal kemik kalinliği sağ kanin bölgesinde 1,91 mm, en düşük ortalama bukkal kemik kalinliği ise 0,35 mm değerinde sağ lateral kesici bölgesinde ölçülmüştür. Sonuçlar: Sonuçlara göre; her üç diş tipinde de ortalama bukkal kemik kalinliği apikal bölgeye doğru artiş göstermiştir. Maksiller bukkal kemik kalinliğini KIBT ile ölçerek dental implant planlamasinda ve diğer cerrahi operasyonlar hakkinda öngörü sahibi olmak daha kolay olacaktir ve ayni zamanda kesin ölçüm değerleri sağlanabilecektir. © 2019 Cumhuriyet University Faculty of Dentistry.
Comparison of the Horizontal Condyle Angle of the Dentulous and Edentulous Patients Using Cone Beam Computed Tomography
(Yuzuncu Yil Universitesi Tip Fakultesi, 2018) Koç, A.
The aim of the present study was to compare the horizontal condyle angle (HCA) between fully edentulous and dentulous patients, as well as to consider the relationship of age and gender with the HCA. This study included 50 patients aged between 25 and 76 years. Their HCAs were measured on cone beam computed tomography (CBCT) images using specialized software. Then, the relationships between the measured HCA and each patient’s age, gender, and dental condition were analyzed. The results of this study revealed that the patient’s gender did not have a significant effect on the HCA (p= 0.850). Additionally, the patient’s dental condition also did not have a significant effect on the HCA (p= 0.772). There was no significant relationship found between the patient’s age and the HCA, although negative correlation was found between these two aspects (r=-0.25, p= 0.865). In the literature, it has been emphasized that a higher HCA may cause the internal derangement of the temporomandibular joint (TMJ). In our study, as the patient’s age increased, so the HCA decreased. In other words, an increase in the HCA was not seen in the older population of patients and increased HCA may cause TMJ internal derangement for some other reasons. © 2018, Yuzuncu Yil Universitesi Tip Fakultesi.

Evaluating Edentulous Mandible Alveolar Crest Dimensions in Posterior Region by Cone Beam Computed Tomography
(Yuzuncu Yil Universitesi Tip Fakultesi, 2020) Koç, A.; Erdem, R.
In this study, alveolar crest height (CH) and width (CW) in patients with edentulous mandible were measured, also the impact of gender and age factors on obtained values were evaluated. Cone beam computed tomography (CBCT) images of 39 males and 38 females were analyzed retrospectively. CH and CW at 10 mm distal of right mental foramen of patients were measured on sectional images. Independent sample T-test and One-way ANOVA test were used for statistical analysis. In CH measurements, there was no significant difference between males and females (p= 0.058). However, males had significantly higher CW values compared to females (p=0.039). Considering age criteria, it was understood that age of patient have no significant effect on CW (p=0.586) and CH (p=0.465). In this study, males just had significantly higher CW values. Besides, age factor had no significant effect on crest dimensions and it was concluded that each patient should be evaluated in itself during dental implant replacement regardless of age and gender. © 2020, Yuzuncu Yil Universitesi Tip Fakultesi.
