Informed consent elements before root end surgery
• Periapical cyst / granulomata (occurring as result of necrotic pulp due to trauma / dental carries)
• Failure of orthograde root canal treatment
Inaccessible apical third of the root
Post / crown, tooth at risk of fracture with removal
• Undiagnosed pathology around apex of tooth root filled / not root filled requiring biopsy
RATIONALE
• Removal of tissue / cyst / pathological tissue, around apex of tooth
• Amputation of root apex and placement of apical seal to prevent further infection
• Pain relief
METHOD
• Local or General Anaesthetic
• Incise around neck of affected tooth with one or two vertical incisions diverging into buccal sulcus
• Reflect muco-periosteal flap to expose bone over apical third of root
• Use rose head burr to expose root
• Use fine rose head burr to divide apical third of root cutting flush with alveolar bone, bevelled to allow retrograde access to root canal.
• Application of retrograde root filling
• Irrigation and closure of flap (absorbable sutures)
BENEFITS AND ANTICIPATED OUTCOME OF PROCEDURE
• Resolution of dental infection
• Diagnosis of pathological lesions
• Pain relief
• Preservation of tooth
• Restoration of normal function / form
RISKS / COMPLICATIONS ASSOCIATED WITH TREATMENT
• Pain
• Swelling
• Bleeding
• Failure of procedure with recurrent infection. 5-10% for anterior teeth. The risk of failure increases with multiple root teeth
• Loosening / loss affected tooth
• Damage / exposure of roots of neighboring teeth
• Upper teeth: entry into maxillary antrum
ALTERNATIVES TO TREATMENT
• No treatment
CONSEQUENCES OF PROPOSED TREATMENT
• Removal of infection / source of infection
• Diagnosis of disease – undiagnosed pathology
• Pain relief
• Retention of affected teeth
• Return to normal function / form
CONSEQUENCES OF NOT ACCEPTING PROPOSED TREATMENT
• Dental extraction
EXTRA ISSUES THAT PATIENTS MAY RAISE
• GA: the procedure is usually undertaken as day case surgery, the patient being discharged the same day
• Antibiotics, analgesia
• Advice regarding oral hygiene/ mouthwash
• Advice regarding time off education / employment
• Healing in 7 - 10 days
• No follow up appointment unless histology review required
ADVICE LEAFLET
• Apical bone cyst
