Definition of dentition in English:



  • The arrangement or condition of the teeth in a particular species or individual.

    • ‘The patient's dentition was normal, and the left mandibular teeth were nontender and immobile.’
    • ‘Their dentition was rather unspecialized and versatile, suggesting an omnivorous lifestyle.’
    • ‘The chief limitation on the number of fossil species studied was the rarity in museum collections of skulls with complete dentition, especially incisors.’
    • ‘Because of the tight correlation between dentition and ecology, dental characters can be used effectively to infer aspects of the diet or ecological niche.’
    • ‘The dentition of the species is highly reduced, with males possessing one or occasionally two pairs of short teeth in the tip of the lower jaw.’
    • ‘The size of the first upper and first lower molar is the least variable in the permanent dentition of most mammals, a pattern that has been confirmed in canids.’
    • ‘The combination of the body proportions and poorly developed dentition suggest that the hatchlings may have required parental care.’
    • ‘The upper dentition, based on socket size, is slightly heterodont, with smaller premaxillary teeth and larger maxillary teeth.’
    • ‘Features one would expect to see in herbivorous dinosaurs that provide some evidence of diet include dentition.’
    • ‘The dentition of these animals was quite peculiar, and very different from that of other cynodonts.’
    • ‘Perhaps the strangest dentition is found in the vampire bats, which have enlarged and bladelike incisors and canines, but molars extremely reduced in size and complexity.’
    • ‘With a mouthful of this murderous fruitlike dentition, tyrannosaurs had a whopping bite, which might have made up for their reduced forelimbs.’
    • ‘The development of the tongue and reduced dentition are reminiscent of the nectar feeding bats in the family Phyllostomidae.’
    • ‘This paper introduces a quantitative method that describes the entire dentition of carnivores, capturing its functional complexity and heterogeneity.’
    • ‘These were impressive-looking beasts easily recognized by their distinctive dentition of intermeshing incisors.’
    • ‘Transmission electron microscopy reveals that the enamel of the lungfish dentition contains no collagen, nor does it stain with picrosirius red.’
    • ‘Despite their morphological and ecological diversity, all rodents share one characteristic: their dentition is highly specialized for gnawing.’
    • ‘The impressions left behind in the underside of the surfboard were more reminiscent of a pinniped's dentition than that of a white shark.’
    • ‘I present a method developed to describe the entire dentition of the Carnivoramorpha and other mammalian meat eaters (Creodonta).’
    • ‘Conodonts have been known for almost as long as there has been paleontology, but their peculiar dentition was all that was known of the group.’
