• Cracked tooth and vertical root fractureA cracked tooth hurts sharply on biting, often when the bite is released

Procedure

• Immature teeth: apexification and regenerative endodonticsIf a young permanent tooth's pulp dies, its root stops growing, with thin walls and an open end
• Restoring the root-filled tooth: cusp coverage and postsA root-filled back tooth breaks easily because it has lost structure
• Root canal treatment: access, cleaning, shaping and fillingA root canal removes the dead or inflamed pulp, disinfects the canals and seals them
• Vital pulp therapy: pulp capping and pulpotomyA pulp that is still alive can often be saved, in part or whole, instead of a full root canal

Dental material

• Irrigants and dressings inside the canalSodium hypochlorite is the main root canal irrigant because it dissolves tissue and kills…
• Root canal filling materials and sealersCanals are filled with gutta-percha, a rubbery core, plus a sealer that fills the gaps

Anatomy and histology

• Root canal anatomy tooth by toothEach tooth has a usual number of roots and canals, but extra canals are common

Topic

• When a root canal fails: retreatmentA root-filled tooth can stay infected or become reinfected
