Which of the following scenarios would most likely necessitate surgical endodontics due to endodontic failure?
Which of the following scenarios would most likely necessitate surgical endodontics due to endodontic failure?
- A patient with a root canal that was completed 10 years ago with no current symptoms.
- A patient experiencing mild sensitivity to cold after a recent root canal.
- A patient with a persistent apical infection despite conventional root canal therapy. (correct)
- A patient needing a routine dental cleaning following successful endodontic treatment.
During an apicoectomy, what is the primary objective of the dentist when examining the resected apex?
During an apicoectomy, what is the primary objective of the dentist when examining the resected apex?
- To identify potential fractures and assess the quality of the apical seal. (correct)
- To assess the overall tooth shade for matching with a dental crown.
- To measure the cementoenamel junction for restorative planning.
- To evaluate the gingival biotype for periodontal considerations.
In which situation would a retrograde restoration be considered the MOST appropriate step during surgical endodontics?
In which situation would a retrograde restoration be considered the MOST appropriate step during surgical endodontics?
- When there is significant coronal decay requiring a full coverage restoration.
- When the tooth exhibits mobility due to periodontal disease.
- When the tooth has adequate coronal structure and requires a fiber post.
- When the apical seal is inadequate and cannot be predictably improved. (correct)

Study Notes
- Surgical Endodontics involves surgical intervention for various dental issues.
Indications for Surgical Intervention
- Endodontic Failure
- Exploratory Surgery
- Biopsy
Endodontic Failure
- Can be caused by persistent infection.
- Severely curved roots can lead to failure.
- Another cause can be perforation of the canal.
- Fractured roots can cause endodontic failure.
- Extensive root resorption can lead to failure.
- Accessory canals that cannot be treated may also be a cause.
Exploratory Surgery
- Done to determine the reason for healing not occurring.
Biopsy
- It involves the removal of tissue from living patients for diagnostic examination.
Apicoectomy
- This is the surgical removal of the apical portion of the root.
- A high-speed handpiece and bur is used.
- Dentists can examine the apex for inadequate sealing of the canal or accessory canals.
- Fractures of the root are another cause.
- Pathological tissue around the root apex can also lead to an apicoectomy.
Apical Curettage
- Necessary to remove the pathological soft tissue around the root apex.
- Curettage is the removal of diseased tissue by scraping with a curette.
Retrograde Restoration
- Also referred to as root endo filling.
- This is completed when an apical seal is not adequate.
- A small preparation is made at the apex.
- The space is sealed with filling materials (gutta-percha, amalgam, or composite.)
Root Amputation
- A surgery to remove one or more roots of a multirooted tooth.
- The crown remains intact.
- It is most often performed on maxillary molars.
Hemisection
- A procedure of cutting the root and the crown lengthwise and removing it.
- It is most often performed on mandibular molars.

Description
Surgical Endodontics involves surgical intervention for various dental issues, such as endodontic failure, exploratory surgery, and biopsy. Endodontic failure can be caused by persistent infection or severely curved roots. Apicoectomy involves the surgical removal of the apical portion of the root.
