Abstract

Aim: To evaluate the prevalence of juxta-apical radiolucency (JAR) and its relationship with the lower third molars and adjacent structures, in 1,054 panoramic radiographs.

Methods: The sample consisted of digital panoramic radiographs of individuals over 18 years of age, with at least one lower third molar. The images were analyzed for the presence of JAR in relation to corticalization, location, impaction depth, relationship with the mandibular canal, angulation, and impaction of the third molar. Data were analyzed using descriptive statistics and the chi-square test, and values of p < 0.05 were considered significant.

Results: A prevalence of 2.75% of JAR was found, with a statistical difference between JAR and gender (p = 0.01), which proved to be predominant in females. The JAR was seen in greater numbers as corticalized (58.63%), lateroapical (48.27%), and mesioangulated (55.17%), as well as in erupted teeth (31.03%). In relation to the mandibular canal, it presented a higher prevalence when superimposed upon the mandibular canal (65.52%).

Conclusions: The prevalence of RJA was 2.75% of the 1,054 evaluated panoramic radiographs. In relation to the mandibular canal, it presented a higher prevalence of superimposition. In addition, most of the RJA were corticalized, in a lateroapical position, associated with teeth in a mesioangular position.
