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...

A large maxillary cyst was treated for 3 months with marsupialization and decompression, followed by surgical endodontic therapy of the affected teeth and cystectomy. Although small cystic lesions will typically heal with nonsurgical endodontic therapy, larger lesions may need additional treatment. Surgical enucleation of a large cystic lesion may lead to damage of other teeth or anatomic struc...

Osseointegrated implants provide predictable restorative support for crowns, restorations, prosthesis abutments, and removable dentures. Their widespread use in recent years has produced different types of complications. Retrograde peri-implantitis, a lesion occurring at the periapical area of an osseointegrated implant, has recently been described. This paper presents a series of reports descr...

background and aim: the main goal of endodontic treatments is eliminating the etiologic factors of pulpal and periapical diseases as well as maintaining this condition via providing a hermetic seal between periodontium and root canal system. if these were not possible through orthograde approach, periradicular surgery and root-end filling are indicated. review of literature: different materials...

OBJECTIVE The purpose of this study was to evaluate the efficacy of erbium lasers for retrograde endodontic treatment, in terms of clinical outcome and therapeutic success. BACKGROUND DATA Apicoectomy with retrograde filling is a well-established surgical procedure to treat teeth affected by persistent periapical lesions. The apical root end is generally removed with burs, and the adjacent pe...

Two case reports describing a new technique of creating a repositionable piezoelectric bony window osteotomy during apicoectomy in order to preserve bone and act as an autologous graft for the surgical site are described. Endodontic microsurgery of anterior teeth with an intact cortical plate and large periapical lesion generally involves removal of a significant amount of healthy bone in order...
