A study was conducted to analyze the morphology of the teeth of white-tufted-ear-marmoset (C. jacchus) black-tufted-ear-marmoset (C. penicillata) and marmosets-white-faced (C. geoffroyi), to compare them among themselves and with other species described in the literature. Teeth of the three species were submitted to macroscopic, microscopic and ultrastructural analyzes. The results were correlated with those of other species. We concluded that: the three species have a similar dental formula, reaching a total of 32 teeth, expressed in the formula 2x: incisors 2/2; canines 1/1, pre-molars 3/3 and molars 2/2, ich are classified as diplodont, anelodont, bunodont and brachyodont.
