RESUMEN
Introduction: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.
