Streszczenie
Tworzenie tkanki kostnej jest widoczne na zdjęciach rentgenowskich w postaci zacienień. Te zmiany są rzadziej spotykane niż przejaśnienia. Chociaż występują zarówno w szczęce, jak i w żuchwie, to w tej drugiej są częstsze. Ich wielkość i położenie są istotne dla diagnostyki różnicowej. Cel pracy stanowiło określenie częstości występowania zacienień na zdjęciach pantomograficznych w grupie pacjentów tureckich. Materiał stanowiło 3435 zdjęć pantomograficznych wykonanych w latach 2015-2017. Rejestrowano zacienienia i klasyfikowano je wg położenia, kształtu i stanu sąsiadujących zębów. Zacienienia znaleziono na 812 pantomogramach (24,71%). Wśród nich najczęstsze było zagęszczające zapalenie kości (16,9%), następnie wysepki kości zbitej (4%) i zwapnienia w tętnicach szyjnych (2,1%). W podsumowaniu należy stwierdzić, że zacienienia są często spotykane na zdjęciach rentgenowskich, ale zazwyczaj nie są diagnozowane lub mylnie interpretowane. Zwiększenie świadomości klinicystów na temat występowania takich zmian zapobiegnie błędnym rozpoznaniom i niepotrzebnemu wdrażaniu dalszych badań z zakresu diagnostyki obrazowej.

Abstract
Bone production in the jaws is identified on radiograms as radiopacities. Radiopaque lesions of the jaws are more rare than the radiolucent ones. Although they are seen both jaws but are more frequent in the mandible. Size of lesion size and localization is important to reveal differantial diagnosis. The aim of the study was to examine the prevalence of radiopaque findings in panoramic radiographs of a sample of the Turkish population. The material consisted of 3435 orthopantomographs of patients examined in the years 2015-2017. All images were evaluated for the presence of any radiopacity. Detected radiopacities were classified and noted by the location, shape and condition of the adjacent teeth. Various radiopaque lesions were found in 812 of radiographs (24.71%). Condensing osteitis is the most common radiopaque lesion (16.9%), followed by osteosclerosis (4%) and carotid artery calcifications (2.1%). In conclusion, radiopacities are frequently seen at radiographs but they are usually underevaluated or misdiagnosed. Increase of clinicians’ knowledge about these formations will prevent the potential misdiagnosis and unnecessary advanced diagnostic imaging.
