Study Notes
Lower Permanent Canine
- Calcification: First evidence at 4-5 months
- Enamel Completion: 6-7 years
- Eruption: 9-10 years
- Root Completion: 12-14 years
Crown Characteristics
-
Mandibular Canine:
- Narrower mesiodistally than maxillary canine
- Longer by 0.5-1 mm
- Less thickness than upper canine
- Root length similar to maxillary canine
- Smoother lingual surface
- Less cingulum development
- May have bifurcated roots (variation)
Labial Aspect
- Mesiodistal Dimensions: Mandibular canine is less than maxillary canine, typically by 1mm
-
Crown Shape:
- Longer appearance due to narrowness mesiodistally and height of contact areas above cervix
- Mesial Outline: Nearly straight, mesial contact area near mesioincisal angle.
- Distal Outline: Convex
- Cusps: Cusp angle in line with center of root, similar to maxillary canine, but mesial cusp ridge is shorter
Distal Aspect
- Contact Area: More cervical than mesial
- Cervical Line: Shallower than mesial
Incisal Aspect
- Geometric outline: Oblong diamond shape
- Dimensions: Mesiodistal dimension is less than labiolingual dimension
- Cusps & Ridges: Cusp tip and ridges likely inclined lingually
Lingual Aspect
- Surface: Flatter, similar to mandibular incisors
- Cingulum: Smooth and poorly developed
- Marginal Ridges: Less distinct
- Other features: Elevations (incisal & marginal ridges, cingulum, labial ridge), short lingual ridge (constricted on incisal 1/3), depressions (single lingual fossa)
Pulp Cavities
- Mesiodistal Section: Narrower than labiolingual
- Labiolingual Section: Similar to upper canine, but may include dentinal island or two separate root canals
- Cervical Cross Section: Ovoid
