Introduction: Phleboliths are calcified thrombi that may originate from an injury to a vessel wall or stagnation of peripheral blood flow. They are not usually observed in maxillofacial areas and are often associated with vascular malformations. Plain radiographs, such as panoramic radiograph, can be a useful tool to detect phleboliths.Case report: In this report, we describe three cases of phleboliths, found in routine radiographs, emphasizing radiographic features in conventional imaging. When evaluating multiple radiopaque structures randomly distributed in plain radiographs, dental practitioners should consider the presence of a phlebolith, particularly when laminations can be observed. Plain radiographs have an important role in detecting phleboliths, however, patients should be referred to other more accurate imaging exams.

The triticeal cartilage (TC) is a tiny oval-shaped cartilage located at the lateral border of the thyrohyoid membrane between the hyoid bone greater horn and the thyroid cartilage superior horn. The exact function o TC is unknown; it has been proposed that TC was the site of the attachment for the triticeoglossus muscle. On panoramic radiographs, calcified TC may be observed in the soft tissues of the pharynx region, positioned inferior to the greater horn of the hyoid bone and adjacent to the superior border of the C4 vertebrae. The major concern of a calcified TC found incidentally in a routine radiographic examination is the differentiation between this alteration and other calcified tissue manifestations that require additional investigations, such as carotid calcified atheroma artery or other neck pathology such as foreign bodies. Thus, this report describes 3 cases in which TC calcifications were incidentally found in panoramic radiographs.
