Name the tooth and hi-lighted portions

Name the tooth and hi-lighted portions

Maxillary first premolar (right side - mesial egde is longer and straighter - two roots so maxial premolar)

Red: Distobuccal cusp (bigger so buccal - more curved so distal)

Yellow: Mesiobuccal cusp (Sharp angle, linger edge)

Name the tooth

Maxillary primary molar (lingual side - mesial is left, distal is right - overall right side of the mouth)

Name the tooth and hi-lighted portions

Maxillary first premolar (two roots, laminated, so we know its maxillary - buccal cusp is bigger than lingual cusp so we know its primary - mesial groove indicates this is the mesial side, therefore right side tooth)

Red: CEJ

Name the tooth and hi-lighted portions

Maxillary first premolar (two cusps with a transverse ridge - right side has a longer straighter edge therefore mesial - upper right tooth - also is more curved all around so it is maxial)

Name the tooth and hi-lighted portions

Maxillary secondary premolar (buccal view - cusp is pretty centered, longer edge is mesial -

Red: CEJ

Name the tooth and hi-lighted portions

Maxillary secondary premolar (lingual view - two cusps with centered buccal cusps therefore maxillary and secondary premolar - mesial is right because longer edge - upper left side)

Red: CEJ

Name the tooth

Maxillary secondary premolar (two almost even length cusps therefore secondary premolar - two cusps so maxillary - lower HOC and slightly longer cusp is buccal side - lingual view because no mesial marginal groove - upper left side)

Name the tooth

Maxillary secondary premolar (two cusps so premolar (not secondary lower) - centered HOC on buccal side (upper in photo), therefore secondary upper premolar - right side is mesial, longer and straighter)

Name the tooth and hi-lighted portions

Mandibular 1st premolar (Longer edge on lower premolar is is distal - off centered buccal cusp means its a primary premolar - lower right side - buccal view)

Name the tooth and hi-lighted portions

Mandibular First Premolar (lingual view because of low cusp - two cusps so first premolar - longer edge for mandibular first molar is distal - lower right side)

Name the tooth and hi-lighted portions

Mandibular first premolar (larger cusp is buccal - red is distal marginal ridge and it is shorter than mesial side - this tooth is bottom right)

Name the tooth and hi-lighted portions

Mandibular first premolar (sharpe medial edge is primary premolar - long edge is distal side - buccal side is bigger - bottom right tooth)

Name the tooth and hi-lighted portions

Mandibular Secondary Premolar (centerd cusp is secondary premolar - longer edge is distal in lower premolar - bottom right tooth)

Name the tooth and hi-lighted portions

Mandibular second premolar (three cusps is mandibular secondary premolar - longer edge of buccal cusp is distal, right side on this image - bottom right tooth)

Name the tooth and hi-lighted portions

Mandibular Secondary Premolar (Buccal side is bigger cusp on a similar plane to lingual cusp) lower mesial marginal ridge in green - lower right side)

Name the tooth and hi-lighted portions

Mandibular secondary premolar (buccal side is on the right - three cusps is lower second premolar - mesial marginal ridge close to us - lower left side)

Name the tooth and hi-lighted portions

Second Mandibular premolar (y shaped cusps, 3 cusps - longer buccal cusp is distal (left side) - lower left tooth)

Name the tooth and hi-lighted portions
