case_images: Surprisingly, the patient provided a previous panoramic radiograph, dating from March 2011 (Figure 3), representing the last radiographic exam for conclusion of orthodontic treatment.
case_images: An additional panoramic radiograph retrieved from the patient's file revealing no sign of sialolith formation.

case_images: Based on the lack of early detecting the sialolith on the orthodontic radiograph, a deeper investigation in the patient's dental files was carried out revealing an additional panoramic radiograph, dating from June 2004, in which no sign of sialolith was detected (Figure 4).
