A radiograph showed destruction of mesial root structure, furcation involvement, and periapical radiolucency in relation to 85 [Figure 1h]. Extraction of 85 was carried out and a band and loop space maintainer was inserted [Figure 1i]. At 11 years of age, all premolars and canines had erupted in the lower arch, and 45 (succedaneous to 85) showed no enamel defect [Figure 1j].

An OPG and radiographs revealed minimal root structure and periapical radiolucencies in relation to 74 and 85 [Figure 2a-c]. A purulent discharge was observed upon deroofing the pulp chambers of 74 and 85 [Figure 2d]. Infected pulp tissue was excavated and an intracanal medicament (Metapex) was placed in these teeth [Figure 2e and f]. The coronal openings were then restored with glass ionomer cement [Figure 2g]. At 11 years of age, the ST of 74 and 85 (34 and 45) had erupted with no enamel defects [Figure 2h].

On examination, 74 and 75 were found to have large caries lesions and showed grade three mobility [Figure 3a. A radiograph revealed a cystic lesion in relation to 74 and 75 with well-defined margins [Figure 3b]. Following extraction, the crowns of 34 and 35 were partially visible in the extraction sockets [Figure 3c and d]. Six months following extraction, 33, 34, and 35 had erupted with no enamel defects [Figure 3e].

An OPG revealed the presence of a radicular cyst in relation to 85 with well-defined margins that had probably resulted in pressure-induced horizontal displacement of 45 [Figure 4a]. However, the patient returned after 3 months, and a radiograph taken revealed partial up righting of 45 [Figure 4b]. Extraction of 85 was carried out [Figure 4c] followed by the placement of a band and loop space maintainer [Figure 4d]. A radiograph taken 3 months later showed further uprighting of 45 [Figure 4e] until its eruption [Figure 4f]. The space maintainer was removed after eruption and no enamel defects were observed [Figure 4g].

An OPG revealed the presence of a large radicular cyst with well-defined margins in relation to 74 and 75 [Figure 5a]. However, computerized tomography (CT) scan images revealed the presence of a radicular cyst in relation to 85, in addition to the larger cyst in relation to 74 and 75 [Figure 5b-e]. Extraction of 74, 75, and 85 were carried out and a lingual arch was placed to preserve space [Figure 5f]. Glass ionomer cement restoration and stainless-steel crown placement was done for 84 [Figure 5g]. After 1 year of treatment, an OPG revealed absence of the cystic spaces and the presence of normal alveolar bone [Figure 5h]. The lingual arch was removed after the eruption of the premolars and no enamel defects were observed [Figure 5i].

On examination, caries was found in 84 and 85 [Figure 6a]. An OPG revealed a large well-defined cystic lesion in relation to 85 [Figure 6b]. CT scan images revealed perforation of the buccal bone caused by the expanding cyst [Figure 6c-g]. A lingual arch was placed for space maintenance [Figure 6h]. At 11 years of age, all premolars had erupted and there was no enamel defect on 45 [succedaneous to 85; [Figure 6i].
