case_images: There was no active discharge of pus and no palpable lymph nodes were detected (Figures 1(a) and 2(a)). Distant displacement of the tooth embryo and discontinuous imaging of the tooth sac bone wall were observed (Figure 1(b)).

case_images: RE at the third-month follow-up visit revealed a decrease in radiolucency at the cyst site (Figure 2(b)). After 5 months, the direction of eruption of the impacted teeth tended to be normal, and new bone formation was evident at the former cyst site (Figure 2(c)). A panoramic radiograph taken at the 9-month follow-up revealed spontaneous eruption of the impacted lower second premolar and first premolar, with no radiolucency around the teeth (Figure 2(d)).

case_images: Histopathologic examination of the sample confirmed our initial diagnosis of a radicular cyst (Figure 3(a)). The oral examination revealed eruption of the first and second premolars on the right side (Figure 3(b)).
