Popis: | Dental size and morphology are easily recorded aspects of phenotypic variations. The majority of pathological variations in shape affect the crown of the tooth. The variations in the crown of the mandibular permanent molars include the occurrence of the sixth and cusp 7 on the first molars and the fifth cusp on the second molars. Cusp numbers and patterns are of great interest to the anthropologist, not only on account of variation in modern human groups, but because they show marked changes throughout the primate evolution. As the variations are always varied, we present a unique case of bilateral, unusual morphology of mandibular first permanent molars with an oblique ridge. |
