Apicoectomy – A review

Apicoectomy using Er:YAG laser—a clinical study

Surgical endodontics was performed using an Er:YAG laser on 23 patients (4 males, 19 females) exhibiting periapical pathosis. After mucoperiosteal flap reflection, osteotomy was performed over the lesion using a low-speed dental engine with a round bur (#6–8). Root-end resection was then performed using an Er:YAG laser (100 mJ, 10 pps) with copious saline coolant. The root apex cavity for the r...

Microsurgical instruments for root-end cavity preparation following apicoectomy: a literature review.

Root-end cavities have traditionally been prepared by means of small round or inverted cone burs in a micro-handpiece. Since sonically or ultrasonically driven microsurgical retrotips became commercially available in the early 1990s, this new technique of retrograde root canal instrumentation has been established as an essential adjunct in periradicular surgery. At first glance, the most releva...

Influence of apicoectomy on the pulps of replanted monkey teeth.

SEM observations of resected root canal ends following apicoectomy.

The purpose of this study was to examine the apical foramen of root apices extracted during apicotomies. A total of 25 teeth extracted from 25 patients admitted to the Department of Conservative Dentistry at Tokyo Dental College's Chiba Hospital were used for the study. All patients were between 22 to 56 years of age at the time of the study, and each of the 25 cases was determined clinically o...

Outcome of orthograde retreatment after failed apicoectomy: use of a mineral trioxide aggregate apical plug.

INTRODUCTION This controlled, single-center historic cohort study project evaluates treatment outcomes of a nonsurgical treatment approach after failed apicoectomy. METHODS The treatment outcomes of nonsurgical retreatment after a failed apicoectomy were evaluated clinically and radiographically. The study cohort consisted of teeth that had received primary root canal treatment and subsequent...
