How would you distinguish a mandibular canine from a maxillary canine?

A

Look at size: narrower than maxillary canine lingual labially and labially

Look for imbrication lines: mandibular canines typically don’t have imbrication lines; is much smoother labially

Look at mesial and distal edges on labial view: mesial more straight and distal more convex

Look at labial ridge: present but not prominent like the maxillary canines

Look at the root from a proximal view: tapered root with mesial inclination but may be bifurcated. Mandibular canines are the most likely anterior teeth to be bifurcated. Prominent root concavities but deeper on mesial than max. canine

Look at cusp: not as pointed or defined as maxillary

Look at cingulum and lingual ridge: not as defined, cingulum low and flattened

Look at marginal ridges: Mesial marginal ridge present but less pronounced than maxillary canine. Distal marginal ridge present but less pronounced than maxillary canine

Look at incisal view: Shape of the crown from an incisal view is asymmetrical (slightly more symmetrical than maxillary canine). Mesial part of the crown has a greater labiolingual bulk. Distal part of the crown appears thinner labiolingually
