Abstract

Clinicians are often faced with endodontic cases that are significantly more challenging than the primary root canal treatment of mature adult teeth. This paper outlines some of the common treatment modalities which can be employed in situations in which either primary treatment has failed, or there is iatrogenic damage or unusual anatomy.

CPD/Clinical Relevance: This paper will provide the reader with advice and techniques for undertaking orthograde endodontic retreatment, hemisection, endodontic surgery and management of teeth with incompletely formed roots.

Article

Primary endodontic treatment is not always successful.1 Teeth which are no longer painful but, after root canal treatment, have a persisting periapical radiolucency or draining sinus may be considered to have ‘survived’. When there is persistent periapical disease and symptoms, treatment is said to be at best unfavourable and at worst to have failed. However, when teeth become symptomatic the clinician must consider intervention, be it via root canal treatment or extraction.

It is essential to consider the time that has elapsed since the root canal treatment was undertaken; healing takes time. Though the ESE recommends monitoring for 4 years,2 evidence suggests that healing will most likely occur within two years of treatment.3 Serial radiographs are essential and patients must be counselled that a treatment may not have failed, especially if a lesion persists but has diminished in size.
