Diagnosis, Management and Follow-Up of a Rare Regional Developmental Disorder: Segmental Odontomaxillary Dysplasia.

Segmental odontomaxillary dysplasia (SOD) is a rare craniofacial developmental disorder. Clinical features include abnormal growth and maturation of bone, premolar agenesis, delayed eruption of permanent molars, and unilateral posterior maxillary enlargement. Radiographic features include altered bone trabeculae, reduced maxillary sinus, pulp stones, and spontaneous resorption of primary molars. The purpose of this report is to describe the case of a seven-year-old boy who presented with dental pain, erythema of the soft tissues of the right maxillary quadrant, severely infra-occluded primary molars and bony expansion of the maxilla. Surgical exploration under general anesthesia preceded removal of the infraoccluded primary molars and histopathological examination of atypical alveolar bone. The unerupted teeth were examined, mobilized, and left in situ. Following stabilization, a removable prosthesis was constructed to aid esthetics. A comprehensive approach to treatment is indicated in such cases.

A multidisciplinary management of a type III dens invaginatus in a maxillary permanent canine.

BACKGROUND: Dens invaginatus affects 0.3-10% of the population; however, few reports document its occurrence in maxillary canines. Management of associated periradicular infections is often challenging. The benefits of computed tomography are well documented in these situations, providing greater clinical information for diagnosis, prognosis and practical management. Many previous reports in the literature utilise this technology but often focus on an endodontic management approach. CASE REPORT: Details of the treatment of a complex type III invagination affecting a maxillary canine, combined with hypodontia and malocclusion is described. Endodontic treatment was deemed inappropriate resulting in extraction of the invaginated canine. The multidisciplinary planning and approach, highlighted the need for close teamwork, shared care and a patient-centred approach. FOLLOW-UP: A 5-year follow-up and review recorded a successful outcome. CONCLUSIONS: This case reinforces the importance of careful investigation and planning in ensuring an optimal outcome when addressing multiple dental anomalies. Extensive consideration of the initial treatment strategy is required, coupled with evaluation of the outcome and longevity of any potential treatment modality to be employed. The consideration of inevitable future restorative treatment is fundamental, highlighting the importance of multidisciplinary planning at diagnosis. Moreover, orthodontic, aesthetic, behavioural and/or social factors may further complicate management in adolescents.
