Güneydoğu Anadolu Popülasyonunda Aksesuar Mental Foramen Prevalansının Konik Işınlı Bilgisayarlı Tomografi İle Retrospektif Olarak Değerlendirilmesi

Abstract

Amaç: Bu çalışmanın amacı aksesuar mental foramenin Güneydoğu Anadolu popülasyonundaki prevalansının ve lokalizasyonunun Konik Işınlı Bilgisayarlı Tomografi ile retrospektif olarak değer-lendirilmesidir.
Materyal ve Metod: Bu retrospektif çalışmada, 2015-2020 yılları arasında Dicle Üniversitesi Diş Hekimliği Fakültesi, Ağız, Diş ve Çene Çene Cerrahisi Anabilim Dalı’na çeşitli nedenlerle başvuran 629 hastaya ait konik ışınlı bilgisayarlı tomografi görüntüleri retrospektif olarak değerlendirildi ve 61 aksesuar mental foramen tespit edilen vaka; yaş, cinsiyet ve lokalizasyon açısından değerlendirildi. Mental foramen ve aksesuar mental foramen arasındaki ortalama mesafesi de hesaplandı ve tüm ölçümler istatistiksel olarak analiz edildi.
Bulgular: Yapılan analizler sonucunda 629 hasta değerlendirildi. Bunlardan 61 tanesinde aksesuar mental foramen tespit edildi. Bunlardan 28 tanesi erkek hasta iken 33 tanesi kadın hastada belirlendi. 56 hastada unilateral aksesuar mental foramen tespit edilirken 5 hastada bilateral olarak tespit edildi. Cinsiyete göre yapılan karşılaştırma sonrasında erkeklerde ortalama değer 1,931 elde edilirken kadınlarda 1,91 olarak tespit edilmiştir. Yapılan istatistiksel analizler sonucunda aralarında anlamlı bir fark elde edilememiştir.
Sonuç: Yapılan değerlendirmeler sonucunda, cinsiyetin ve yaşın mental foramen ile aksesuar mental foramen arasında bulunan mesafeye etkisinin olmadığını düşünmekteyiz. Daha kesin sonuçlar için daha fazla örneklem ile daha geniş çalışmalar yapılması gerekmektedir.

Retrospective Evaluation of The Prevalence of Accessory Mental Foramen in Southeastern Anatolian Population By Cone Beam Computed Tomography

Abstract

Background: The aim of this study is to retrospectively evaluate the prevalence and localization of the accessory mental foramen in the Southeastern Anatolian population using Cone-Beam Computed Tomography. Materials and Methods: In this retrospective study, cone beam computed tomography images of 629 patients who applied to Dicle University Faculty of Dentistry, Department of Oral and Maxillofacial Surgery between 2015 and 2020 for various reasons were retrospectively evaluated and 61 accessory mental foramen fixations were made. the reported case; Age, gender and localization were evaluated. The mean distance between the mental foramen and the accessory mental foramen was also calculated, and all measurements were then statistically analyzed. Results: As a result of the analysis, 629 patients were evaluated. AMF was detected in 61 of them. While 28 of them were male patients, 33 of them were determined in female patients. While unilateral accessory mental foramen was detected in 56 patients, it was detected bilaterally in 5 patients. After the comparison made by gender, the mean value was found to be 1.931 for men, while this value was found to be 1.91 for women. As a result of the statistical analysis, no significant difference was found between them. Conclusions: As a result of the evaluations, we think that gender and age have no effect on the distance between the mental foramen and the accessory mental foramen. Larger studies with larger samples are required for more precise results.
