Anatomy + Morphology + Outline - Mandibular central to canine

Mand. Centrals - Overview

• 1:1

• Pulp outline wider LL.

• Root curve D or DL.

• Remove lingual shoulder if present.

• Outline access form: OVal/rounded triangle (dep. on pulp horns).

• Entry point: ling surface above cingulum.

• CEJ pulp outline oval, wider LL than MD. Midroot canal outline still oval, canal constricted & narrower labiolinguallt.

• Dentinal bridhe present in pulp chamber → divides root into 2 canals.

• 2 canals join & exit through single apical foramen but can also just be 2 sep. canals.

Mand Centrals - Outline form access

• Small & narrow anatomy.

• Outline form: Oval/trianguar 

—> Triangular: Short incisal base, long M&D legs → compressed long triangle. 

—> Oval form: Less prominent pulp horns. Narrow MD & long incisogingivaly. 

• Lingual shoulder completely removed to expose canal/canals. 

• 2 canals = B&L

• Lingual canal missed. 

• Access extended into cingulum gingivally. 

Mand Lateral - Overview

• 1:1/2 (L&L) 

• Root: Straight curvature (distally somtimes). 

• Crown tilted distally on root. 

• Pulp chamber: Wider LL. 2 canals may join apically. 

• Lingual shoulder: PROMINENT. —> REMOVAL.

• Outline form: Narrow oval (long incisogingivally).

Mand lateral - Outline form acess

• Narrow oval or triangular if horns prominent. 

• Entry point: Lingual surface above cinhulum → extended deeper gingivally for better access. 

• Access may need lingual extention to locate hidden second canal. 

Mand canine - Overview

• 1/2:1/2

• Canals L+L.

• Canal wider BL but narrow MD.

• Lingual shoulder removal ti access ling. wall OR 2nd canal.

Mand Canine - Outline access form

• Access: Oval/slot shaped w/matching pulp chamber width.

• Incisal extention: Up on incisal edge for straight line access.

• Gingival extention: Into cinhulum, locating ling. canal.
