Introduction

  • Endodontics Endodontics: basic is the branch of dentistry dealing with the diagnosis and treatment of diseases of the pulp.
  • Root Canal Therapy (RCT) is an endodontic procedure whereby the affected pulp is removed altogether (pulpectomy), the canal cleaned and shaped and then filled with suitable materials.
  • Theendodontic triadmust be adhered to for a successful outcome and involvespreparation,sterilizationandobturation.
  • RCT includes conventional RCT (orthograde) and surgical RCT (retrograde).
  • This component describes only conventional RCT.
  • Once a tooth is mature it can function without any pulp at all as long as it is periodontally healthy.

Uses

  • Fractured crown with pulp exposure Dental fracture Teeth tooth fracture Tooth: complicated crown fracture.
  • Deep carious lesions leading to pulp exposure.
  • Pulp exposure due to excess wear (attrition or abrasion).
  • Pulp injury resulting in hemorrhage or necrosis in a closed canal (usually a discolored tooth) Dental trauma: tooth discoloration Teeth pulpal necrosis 01.
  • Opaque teeth when transilluminated.
  • Pulp abscess or periapical abscess Teeth: periapical abscess.
  • Reimplantation of avulsed or luxated tooth Dental trauma: tooth luxation/avulsion.

Advantages

  • Alleviates pain and infection.
  • Considered preventative for future abscessation where a dead tooth is treated.
  • Allows retention of tooth form and function.
  • Less invasive and traumatic than surgical extraction.
  • Maintenance of mandibular strength (if mandibular canine treated).
  • Highly successful if performed well.

Disadvantages

  • Contra-indicated in fractured deciduous teeth Dental fracture.
  • Contra-indicated in teeth with an incomplete apex.
  • Contra-indicated in teeth with vertical root fractures Dental trauma: root fracture.
  • Contra-indicated in teeth with significant, uncontrolled periodontitis Periodontitis.
  • Impossible in old animals with inaccessible or sclerosed root canals.
  • Involves significant expenditure in obtaining correct materials and instruments.
    Verytechnique sensitive. Adequate trainingmustbe obtained before attempting this procedure in a live patient.
  • More expensive than extraction.
