Indications
Periradicular surgery should always be very carefully considered and where possible re-root treatment is the preferable option[3]. However, in cases where re-root treatment is not possible/will not correct the problem or if patient factors are preventing re-root treatment, periradicular surgery is indicated[4].
These may prevent complete cleaning and obturation of the canals. For example; root canal calcification, pulp stones, severely curved roots, bifurcations, secondary roots, lateral canals, delta apexes, internal and external resorption resistant to conventional treatment, incomplete apex[3].
These include the formation of ledges, perforation of root or floor of pulp chamber[1], extruded root filling material[2], file breakages or underfilling the canals. However, these are only indications for periradicular surgery if they’re causing a persistent periapical radiolucency, swelling and pain[5][1][2].
Identification of possible root fractures[3][2] or perforations[4].
This may be used in suspicious and/or non-healing lesions or when a patient presents with uncharacteristic signs and symptoms of periapical areas.

Treatment outcomes
A range of benchmarks has been used to assess outcomes of periradicular surgery widely[6], this therefore makes comparisons for outcomes of surgery between various studies more challenging. The classification that most published papers adopt is by Rud et al[7] which evaluates the success based on radiographs. However, clinical criterias have also been considered which has been outlined by the Royal College of Surgeons (England) in determining outcomes of periradicular surgery.
Clinical | Radiological | |
---|---|---|
Successful Outcome | Previous signs & symptoms are resolved | Regular PDL space or slightly wider.
Previous periapical radiolucency reduced or resolved with normal replacement of bone and lamina dura. Sound roots without resorption. |
Incomplete Outcome | Previous signs & symptoms are resolved | Some bone seen surrounding root of tooth with gradual replacement but still incomplete healing.
Periapical radiolucency still present. |
Uncertain Outcome | Indefinite symptoms - slight ache or discomfort associated with tooth in question | Some bone seen surrounding root of tooth with gradual replacement but still incomplete healing.
Periapical radiolucency still present. |
Unsuccessful Outcome | Unresolved signs & symptoms associated with tooth in question | No bony replacement seen surrounding root of tooth. |
If the periapical surgery is unsuccessful, investigations must be carried out to determine the causes of failure before further treatment can be done.[4][8] However, re-surgical interventions are usually not as successful (35.7%)[4] and there is a consensus on refraining from re-surgery.[8]
Other options to consider if periapical surgery has failed, besides re-surgery would be:
- Leave it & monitor
This can be advised if the patient is symptom-free but has persisting radiographic indications of disease
- Extract the tooth
- Re-perform root canal treatment
