SKA Week 5+6: Identifying Teeth

maxillary central incisor

sharp mesioincisal angle, rounded distoincisal angle, cingulum in the middle

maxillary lateral incisor

palatal pit, incisal edge slopes distally, cingulum more distal

maxillary canine

crown is short + fat, prominent lingual ridge, mesial cusp slope is shorter than distal cusp slope

mandibular central incisor

rectangular, incisal edge flat, smallest teeth

mandibular lateral incisor

sharp mesioincisal angle, round distoincisal angle, incisal edge slopes distally, no palatal pit

mandibular canine

crown is taller + skinnier, less pointy, mesial cusp slope is shorter than distal cusp slope

maxillary 1st premolar

canine fossa + mesial marginal developmental groove, 2 roots, buccal cusp longer than lingual cusp

maxillary 2nd premolar

buccal cusp + lingual cusp same length, no canine fossa + mesial marginal developmental groove, shorter central developmental groove + less supplementary grooves, oval shaped occlusal surface

mandibular 1st premolar

severe lingual inclination, diamond shaped occlusal surface, buccal cusp longer than lingual cusp, snake eye, mesial lingual developmental ridge

mandibular 2nd premolar 2 cusps

oval shaped occlusal surface, U/H shaped central developmental groove

mandibular 2nd premolar 3 cusps

square shaped occlusal surface, buccal cusp >mesiolingual cusp > distolingual cusp, Y shaped central developmental groove
