Follow-up study of apicoectomized molars

Area of Science:

• Endodontics
• Oral Surgery

Background:

• Apicoectomy is a surgical procedure to treat endodontic complications.
• Molars present unique challenges due to their root anatomy.

Purpose of the Study:

• To evaluate the clinical outcomes of apicoectomy on molars.
• To identify factors influencing healing after molar apicoectomy.

Main Methods:

• Retrospective study of 46 molars with 93 resected roots.
• Clinical examination and radiographic assessment (stereoscopic, orthopantomogram) 1-6 years post-surgery.
• Analysis of healing based on root resection extent and root filling technique.

Main Results:

• Overall, 71% of apicoectomized teeth showed complete healing.
• 81% of resected roots achieved complete healing.
• Higher complete healing rates were observed when approximately half the root was resected compared to one-third.
• Orthograde root filling during resection yielded better results than retrograde or prior orthograde fillings.
• Presence of multiple periapical lesions in other teeth correlated with fewer complete healings in the resected group.

Conclusions:

• Apicoectomy is an effective treatment for molar endodontic issues.
• Root resection extent and root filling technique significantly impact healing success.
• Comprehensive oral health, including managing multiple periapical lesions, is crucial for optimal apicoectomy outcomes.
