Naming high order

Root to crown ratio
Root length divided by crown length Large number means large root Small number means small root Canines are the biggest 3/2 optimum 1/1 minimum
Molars cusps
Mesiobuccal cusp
Distobuccal cusp
Distolingual cusp
Mesiolingual cusp
Molar ridges
Mesial/ distal cusp ridge of the mesial buccal cusp
Mesial/ distal cusp ridge of the distal Buccal cusp
Mesial/ distal cusp ridge of the distal lingual cusp
Mesial/ distal cusp ridge of the medial lingual cusp
marginal ridges
Mesial
Distal
Cingular
Lateral incisors have a mesial and distal marginal ridge that meet in the central tooth cervical line to form this budge
Mamelon
Form on adult incisors
3 labial lobes
Growth center location
Shaved down when adult
Perikymata
Wave like enamel ripples on newly erupted teeth
Molar grooves
Central groove Buccal groove Lingual groove Mesiobuccal triangular groove Mesiolingual triangular groove
Molar fossae
Mesial
Central
Distal
Bottom of the fossae are pits
Root anatomy
CEJ separate the crown from root Root apex Root axis line Root trunk Root bifurcation or trifurcation Cervical line Apical forming
Height of contour
Crest of curvature
A line parallel to the root axis line around the tooth
Location where this line first touches the tooth
Aka places where adjacent teeth touch
Embrasure spaces
Gaps where adjacent teeth touch Facial embrasure Lingual embrasure Occlusal or Incisal embrasure Cervical embrasure or interproximal space
Anthropometric curve of spee
Maxillary curve is convex
Mandibular curve is concave

Interocclusal relation
Buccaneers mandibular molar meet the lingual maxillary molar
Protects the cusps of the teeth
Naturally occurs with the lingual tilt of mandibular teeth and facial tilt of the maxillary teeth
Ideal class 1 occlusion relationship
Mesiobuccal cusp of the maxillary 1st molar
Meets
Mesiobuccal groove of the mandibular 1st molar
