Abstract:

Purpose: This study aims to investigate whether the ultrasound (USG) technique is useful in the visualization of periapical pathologies observed in panoramic (PR) and periapical radiographs (PAR), as well as to determine the possible effect of the size and localization of periapical injury (PAL) on appearance. It is also among the purposes to investigate whether the relationship between the size of the injury and the vascularization is. Method and method: The work was carried out over 46 people. The teeth associated with periapical lesions (PALs) were classified in six groups for each chest as the anterior, the premolar and the molar teeth. The MD sizes of the PAL in the periapical radiographs were classified into three groups to be < 5 mm, between 6-10 mm and > 10 mm. The mesio-distal (MD) width of lesions was measured and recorded along with the corresponding tooth number.All USG examinations (Aplio 500 Toshiba Medical Systems Corporation, Otawara, Japan) were conducted using B-Mod and high-frequency (7-18 MHz PLT-1005BT) or (14-7.2 MHz PLT-1204BT) linear scanning tests.™The MD size of periapical lesions displayed in the transversal direction was measured and recorded.Colour doppler USG also assessed the vascularization of PA lesions.The MD sizes of PALs were measured by three different visualization methods (PAR, PR and USG) and the binary compatibilities were compared.Results and Results: The localizations of PALs have been found to have an effect on being visible in USG (p < 0.001). According to the regions, it was determined that the lesions in the frontal area of the macular may be easily visible, and the lesions in the frontal area of the macular and mandibular molar may not be seen with USG. Furthermore, there was no relationship between the size of the injury and the colour doppler USG vascularization findings (p > 0.05).
