Abstract

Teeth play an important role in mastication and speech. In fossils, teeth found within the rima oris were usually embedded in the jaws, although mineralised structures with similar histological patterns as teeth were found in fossils even before jaws appeared. Conodonts were the complex structures having enamel and dentine which were described in the earliest jawless vertebrates. These fossil findings led researchers to believe that teeth and jaws evolved as well as developed independently. Since the evolution of Homo sapiens from the our chimpanzee various factors such as the mastication pattern, food ingested and the processing of this foodstuff by fire and other tools affected the entire course of evolution. Further, development of mastication is interlinked to supplementary bodily characteristics like size of the brain and bipedalism, which also contributed to crucial happenings like development of linguistics and speech. So, a brief comprehension of these interactions is necessary to support the current evidence-based scenarios. Therefore, the aim of this review is to understand the various evolutionary aspects of dentition and basic genetic interactions which control tooth initiation, morphogenesis and patterning.
