Background:
Cemento-ossifying fibroma (COF) is a benign, non-aggressive fibro-osseous tumor in which normal bone is replaced by fibrous tissue containing collagen fibers, bone, or cementum-like material. Although COF is rare in children, its occurrence requires careful management due to its potential impact on tooth development and occlusion. Surgical excision is the widely used treatment; however, post-operative occlusal guidance is crucial, particularly in pediatric patients.
Case Report:
This case report presents the early intervention using a preformed eruption guidance appliance (EGA) following the excision of COF in a 5-year-old boy. The patient exhibited premature loss of the primary canine and displacement of the devel-oping permanent tooth bud. After surgical excision, an EGA was applied to facilitate proper eruption of the successor teeth and optimize oral muscle function. Over a four-year follow-up period, the permanent teeth in the affected area erupted favorably, and intercuspal relationships improved during the transition from primary to mixed dentition.
Conclusions:
Given the limited research on the long-term effects of COF on developing dentition, long-term follow-up and additional studies are necessary to further evaluate its impact and the effectiveness of eruption guidance appliances in pediatric patients.
