Developmental anomalies affecting the morphology of teeth – a review

Resumo

The development of tooth is a complex process
wherein there is series of interactions between the ectoderm and
ectomesenchyme. The role of genes in determining the shape and
form of a specific tooth has already been defined, the alterations
in which can lead to a variety of anomalies in regards to number,
size, form, shape, structure, etc. Objective: To review the literature
on the developmental anomalies of teeth. Literature review: The
developmental anomalies affecting the morphology exists in both
deciduous & permanent dentition and shows various forms such
as gemination, fusion, concrescence, dilacerations, dens evaginatus,
dens invaginatus, enamel pearls, taurodontism or peg laterals. These
anomalies have clinical significance concerning esthetics, malocclusion
and more importantly predisposing the development of dental
caries and periodontal diseases. Conclusion: Knowledge of various
diagnostic criteria for identification of these developmental anomalies
is significant for early diagnosis and pertinent treatment.
