Abstract

This article describes the multidisciplinary management of a 9-year-old boy who presented with severe hypodontia. Treatment included preventive dentistry and early treatment to address his concerns regarding the poor aesthetic appearance of his anterior teeth. This included composite resin restoration of his upper permanent central incisors and a pre-adjusted edgewise appliance to close the diastema. A unique restorative technique was used to retain the closed diastema and restore the spaces of the missing lateral incisors.

Clinical Relevance: To illustrate the importance of multidisciplinary dental care in the treatment of patients with severe hypodontia.

Article

Hypodontia is the term used to describe the developmental absence of one or more teeth, excluding the third permanent molars. Oligodontia describes the developmental absence of six or more permanent teeth (excluding third permanent molar teeth) and anodontia refers to the complete absence of teeth.1 The prevalence of hypodontia in the primary dentition ranges from 0.1% to 0.9% with no specific gender predilection.1,2 In the permanent dentition, the prevalence is reported to be from 3.5% to 6.5% with a female preponderance of 3:2.2,3 The most commonly affected tooth (excluding third permanent molars) is the mandibular second premolar tooth, followed by the maxillary permanent lateral tooth and the maxillary second premolar tooth.1 Oligodontia or severe hypodontia is much less common, with a reported prevalence of 0.19%, and may involve teeth that are rarely absent, such as permanent canine and molar teeth.4 Teeth that are present may be conical in shape, or taper towards the incisal edge. An association between hypodontia and microdontia has been established in the literature. Gungor and Turkkahraman examined dental casts of patients with hypodontia, and found that teeth were significantly smaller than controls. Primary teeth may be retained in excess of normal lifespan in the absence of permanent successors.5
