Abstract

Amaç: Maksillofasiyal konik ışınlı bilgisayarlı tomografi görüntülerinde karşılaşılan rastlantısal bulguların yerini, tipini ve sıklığını geriye dönük olarak incelemektir.
Gereç ve yöntem: Çalışmada, 2018-2021 yılları arasında sadece implant planlaması amacıyla alınmış konik ışınlı bilgisayarlı tomografi görüntüleri geriye dönük olarak rastlantısal bulgu varlığı açısından değerlendirilmiştir. Görüntüler, iki deneyimli dentomaksillofasiyal radyolog tarafından geriye dönük olarak incelenmiştir. Rastlantısal bulgular bulundukları bölgeye göre; hava yolu bulguları, gömülü diş-kök varlığı, temporomandibular eklem bulguları, endodontik lezyonlar, osteoskleroz ve yumuşak doku kalsifikasyonları olarak sınıflandırılmıştır.
Bulgular: Çalışmada 109’u erkek 91’i kadın olan toplam 200 hastanın (yaş ortalaması 50,54 (36-68)) konik ışınlı bilgisayarlı tomografi görüntüleri incelendi. Rastlantısal bulguların dağılımı açısından cinsiyetler arasında anlamlı fark bulunamadı (p=0,857). Yaş ile rastlantısal bulguların gözlenmesi arasında korelasyon yoktu (p=0,525). Rastlantısal bulguların en çok görüldüğü bölge hava yolu olup ardından sırasıyla, gömülü diş ve artık kökler, TME bulguları, endodontik lezyon, osteoskleroz ve yumuşak doku kalsifikasyonları gelmektedir.
Sonuç: Çalışmada değerlendirilen görüntülerin %88’inde rastlantısal bulgu gözlenmiş olup çalışmadaki hasta başına düşen rastlantısal bulgu sayısı 1,16 dır. Konik ışınlı bilgisayarlı tomografi görüntülerini değerlendiren dentomaksillofasiyal radyolog veya hekimlerin, tomografi istek endikasyonuna bağlı kalmaksızın görüntü alanına giren tüm yapıları detaylı olarak değerlendirmesi, takip/tedavi gerektirebilecek durumların teşhisi ve hastanın yönlendirilmesi açısından son derece önemlidir.

INCIDENTAL FINDINGS IN CBCT IMAGES : A CROSS-SECTİONAL STUDY

Abstract

Objective: To evaluate the location, type and frequency of incidental findings encountered in maxillofacial cone beam computed tomography images.
Material and methods: In the study, cone-beam computed tomography images taken only for implant planning between 2018-2021 were evaluated retrospectively for the presence of incidental findings. The images were retrospectively reviewed by two experienced dentomaxillofacial radiologists. Incidental findings were classified as airway findings, impacted tooth-root presence, temporomandibular joint findings, endodontic lesions, osteosclerosis, and soft tissue calcifications according to their location.
Results: In the study, cone beam computed tomography images of a total of 200 patients(mean age 50.54(36-68) years), 109 male and 91 female, were analyzed. There was no significant difference between the genders in terms of the distribution of incidental findings(p=0.857). There was no correlation between age and the presence of incidental findings(p=0.525). The region with the most incidental findings is the airway, followed by impacted teeth and residual roots, TMJ findings, endodontic lesion, osteosclerosis and soft tissue calcifications.
Conclusion: Incidental findings were observed in 88% of the images evaluated in the study, and the number of incidental findings per patient in the study was 1.16. It is extremely important for dentomaxillofacial radiologists or dentists who evaluate cone beam computed tomography images to evaluate all structures in the field of view in detail, regardless of the tomography request indication, in terms of diagnosing conditions that may require follow-up/treatment and guiding the patient.
