Osseous lesions in the maxilla can represent ossifying fibroma, fibrous dysplasia, amelogenesis imperfecta
, or osteogenesis imperfecta.
That open-bite is related to calculus accumulation, might contribute also to the calculus accumulation in children with amelogenesis imperfecta
who present with open-bite [Stewart et al.
This clinical report describes the prosthodontic treatment for a 28-year-old male diagnosed with Type 1 hypoplastic amelogenesis imperfecta
Hypoplastic Amelogenesis Imperfecta
Several types of hypoplastic amelogenesis imperfecta
have been described.
The researchers say a determination of the gene's exact location should boost their understanding of a rare, hereditary weakness of tooth enamel called amelogenesis imperfecta
However, the genes regulating enamel and dentine formation are highly specific for teeth, and their mutations are associated with dental disorders such as amelogenesis imperfecta
, dentinogenesis imperfecta, dentine dysplasia and isolated anomalies of tooth number and size [Bailleul-Forestier et al.
Recent findings, however, have excluded KLK4 as a candidate gene in amelogenesis imperfecta
(27,28) but suggested possible involvement of KLK4 mutations as a cause of the recessive form of hypomaturation amelogenesis imperfecta
[Seow, 1995] and pre-term births [Seow, 1996] were also excluded, as these conditions have been associated with altered rates of dental development.
Changes in dental enamel such as amelogenesis imperfecta
, dentinogenesis imperfecta, hypoplasia, diffuse opacities, white spot lesions, tetracycline staining, erosion, fluorosis, white cuspal and marginal ridges were excluded from the study.
