Case report of an Afro-Caribbean adolescent with moderate hypodontia managed with a partial flexible denture Shaun Ramlogan Vidya Raman Dental Update 2024 50:4, 707-709.
A 14-year-old male of Afro-Caribbean descent presented with moderate hypodontia, missing some of the permanent mandibular premolars and the lower central incisors, which was a rare finding. There were no apparent associated systemic or syndromic relationships. The main dental concerns were aesthetics, function and space maintenance until adolescent craniofacial bone growth had ceased. Thus, an initial intervention entailed provision of a unilateral removable partial flexible denture that was acceptable to the patient and provided a suitable aesthetic result for the young person. This approach was preferred to a ‘band and loop’ appliance proposed in the literature because the removable partial denture supported function and aesthetics.
CPD/Clinical Relevance: Unilateral removable partial flexible dentures may be useful in mid-adolescent cases of hypodontia.
Article
Congenitally missing teeth, or agenesis of teeth, refers to the lack of development and oral presentation of teeth as determined clinically and radiographically. Various classifications have been proposed in the literature, with hypodontia being defined as few teeth absent (<6 teeth, excluding the third molars), oligodontia or severe hypodontia defined as many teeth absent (≥6 teeth, excluding the third molars) and anodontia defined as the complete absence of teeth.1,2,3,4 Further classifications of hypodontia include mild hypodontia representing fewer than three missing teeth and moderate hypodontia with fewer than six missing teeth have been also suggested.5
The tooth development stage may be affected by many genetic factors. The commonly cited genes associated with teeth agenesis include MSX1, PAX9, TGFA, AXIN2, and potentially a locus on chromosome 10.6,7,8,9,10 Congenitally missing teeth may be either non-syndromic or syndromic, with the most commonly reported conditions being Down syndrome, ectodermal dysplasia and labio-palatal clefts.11
