    Journal: Eur Arch Paediatr Dent; 2014 Dec; 15(6):449-54. PubMed ID: 25091626.
    Abstract:
    BACKGROUND: Severe hypodontia is a condition characterized by developmental absence of six or more teeth and affects 0.14-0.3% of the overall population. Hypodontia can have a marked psychosocial effect and functional implications for a growing child. CASE REPORT: A 10-year-old girl with a medical history of hypothyroidism and repaired spinal bifida was referred to the Leeds Dental Institute as she was becoming increasingly concerned about her appearance. On clinical examination, the patient had severe wear of her over-retained maxillary primary central incisors, microdontia of mandibular anterior teeth (32, 34, 41, 42, 43), and loss of anterior vertical dimension. Radiographic examination revealed that the patient had 11 missing permanent teeth (14, 13, 12, 11, 21, 22, 23, 24, 31, 35, 44), an ectopic mandibular left canine and taurodontism of the permanent molars. TREATMENT: Management of the patient included an intensive preventive programme with placement of fissure sealants; scaling of calculus deposition on microdont teeth; composite resin reconstruction of microdont teeth; fabrication of removable partial overdentures tailored aesthetically to match the patient's age; orthodontic consultation and monitoring for the eruption of ectopic canine and permanent dentition. The patient and her parents reported marked improvement in self-esteem following dental treatment. FOLLOW-UP: After 2 years of follow-up, a new pair of dentures were made and designed to allow ease of eruption of the existing permanent dentition. All permanent teeth have erupted. The patient is ready for further assessment and planning for future orthodontic and restorative/implant treatment. CONCLUSION: This case illustrates the essential role of the paediatric dentist in the management of hypodontia in the mixed dentition stage.
