A comparative study of the occlusal surface of the mandibular 1st and 2nd premolar in Ivory Coast

: The first mandibular premolars are usually described as teeth with disproportionate cusp. The vestibular's is bulkier and higher than the lingual one. This study confronts this description with the clinical realities observed in Ivory Coast by comparing first mandibular premolars with the seconds. It points out: a slight difference of volume between the first and second mandibular premolars a less important disproportion between the lingual and vestibular cusp of the first mandibular premolar which morphology tends towards the second's.
