BACKGROUND: Vertical root fracture (VRF) is a diagnostic challenge for dentists. Cone-beam computed tomography (CBCT) scans provide accurate three-dimensional images of teeth enabling detection of VRFs. This in-vivo study compared the accuracy of CBCT and exploratory surgery for detection of VRFs in endodontically-treated teeth. METHODS: Forty endodontically-treated teeth of 40 patients with clinical signs and symptoms of VRFs were evaluated. No fracture line was detectable on periapical radiographs...

Biofilms are the main cause of endodontic failures. Even the best executed endodontic treatment can fail, when the infection is resistant to treatment or when it is located in inaccessible areas, such as the external surface of the root apex. The purpose of this study was to evaluate, by scanning electron microscopy, the presence of bacterial biofilm on endodontically treated teeth considered clinical failures and suitable for apical surgery. Root apices were collected from 20 teeth undergoing apical surgery and one negative control and analyzed under SEM...

Mitochondrial disease (MD) represents a category of metabolic disorders with a wide range of symptoms across a variety of organ systems. It occurs with an incidence of greater than 1:5000 and can be difficult to specifically diagnose because of the variety of clinical presentations and multiple genomic origins. Although phenotypically variable, MD symptoms often include hypotonia, cardiac defects, dysautonomia, and metabolic dysfunction. Mitochondrial disease presents a unique challenge in terms of anesthetic management, as many anesthetic drugs suppress mitochondrial function...

BACKGROUND: A fracture of root canal instruments, with a fractured piece protruding beyond the apex, is a troublesome incident during an endodontic treatment. Locating and retrieving them represents a challenge to maxillofacial surgeons because it is difficult to access due to the proximity between the foreign body and vital structures. Although safe and accurate for surgery, radiographs and electromagnetic devices do not provide a precise three-dimensional position. In contrast, computer-aided navigation provides a correlation between preoperatively collected data and intraoperatively encountered anatomy...

Any insult to the pulp during its development causes cessation of dentin formation and root growth. Pulpal status and degree of root development are the decisive factors in the treatment approach. Various treatment options have been tried like surgery with root-end sealing, calcium hydroxide-apexification, placement of apical plug and regenerative endodontic procedures to induce apexogenesis. An ideal scenario for a necrosed tooth with immature root would be continued root development coupled with regeneration of pulp tissue...

An otherwise healthy 34-year-old man was referred to our ear, nose and throat (ENT) clinic for a bilateral maxillary radiologic opacity. This condition was accidentally discovered with a panoramic radiography performed during a follow-up visit after a bilateral endodontic treatment. The patient did not report any specific sinonasal symptom such as purulent nasal discharge, loss of smell and cough, apart from an unspecific sinus pressure. The CT scans showed a bilateral inflammatory process into the maxillary-ethmoidal sinuses and an iron-like density within the maxillary sinuses, while nasal endoscopy showed purulent discharge in the ostiomeatal complex...

Acute dental abscess is a frequent and sometimes underestimated disease of the oral cavity. The acute dental abscess usually occurs secondary to caries, trauma, or failed endodontic treatment. After the intact pulp chamber is opened, colonization of the root canals takes place with a variable set of anaerobic bacteria, which colonize the walls of the necrotic root canals forming a specialized mixed anaerobic biofilm. Asymptomatic necrosis is common. However, abscess formation occurs when these bacteria and their toxic products breach into the periapical tissues through the apical foramen and induce acute inflammation and pus formation...

Increased use of the surgical operating microscope in endodontic surgery has elucidated many shortcomings of previous techniques and along with microsurgical instruments and new more biologically acceptable root-end filling materials has started the new microsurgical era in surgical endodontics. Endodontic microsurgery is a minimally invasive technique that results in less postoperative pain and edema and faster wound healing. It offers a significantly higher success rate than traditional apical surgery technique...

OBJECTIVE: to evaluate productivity targets achievement (PTA) in Dental Specialty Centers (DSCs) from Maranhão State, Brazil. METHODS: this was an ecologic study using secondary data; an indicator for PTA was created for each subgroup of procedures. RESULTS: 25 DSCs were evaluated; the PTA was higher for basic procedures (n=19), followed by endodontics (n=11), oral surgery (n=9) and periodontics (n=8); the best results were obtained at DSCs type II; higher PTA was associated with financial anticipation (basic procedures) and higher Human Development Index, life expectancy and social exclusion rate (endodontics); lower PTA was associated with larger population (endodontics/oral surgery), adherence to the Pact for Health (periodontics/endodontics), larger number of specialties (periodontics) and bigger DSC (oral surgery)...

Although it is challenging, the early diagnosis of a vertical root fracture (VRF) is crucial in order to ensure tooth preservation. The purpose of this clinical case report was to describe reparative surgery performed to treat a tooth affected by an incomplete VRF. A 26 year old male patient was suspected to have a VRF in a maxillary left central incisor, and an exploratory flap was performed in order to confirm the diagnosis. After detecting the fracture, the lesion was surgically treated, the fracture and the infected root-end were removed, and a platelet-rich plasma membrane was used to cover the defect in order to prevent bacterial migration...

Calcifying cystic odontogenic tumor (CCOT) is an uncommon benign cystic neoplasm of the jaw that develops from the odontogenic epithelium. Invasion into the maxillary sinus by a CCOT is not a typical, and the recurrence of the cystic variant of CCOT in the posterior maxilla is rare. This report describes a recurrent CCOT occupying most of the maxillary sinus of a 24-year-old male patient. As a treatment, marsupialization was carried out as a means of decompression, and the involved teeth were all endodontically treated...

The modern surgical endodontic treatment is a safe and predictable procedure with high success rate. However, several factors can retard or impede the proper healing process. Use of a high speed handpiece during hard tissues management (osteotomy and apical resection) can potentially be one of these factors. Formation of metallic debris from the surgical diamond burs, production of necrotic local tissue due to overheating and the direct liberation of air from conventional handpiece into the working area are potential irritants able to delay the tissue healing...

BACKGROUND: When primary root canal therapy fails, periapical lesions can be retreated with or without surgery. Root canal retreatment is a non-surgical procedure that involves removal of root canal filling materials from the tooth, followed by cleaning, shaping and obturating of the canals. Root-end resection is a surgical procedure that involves exposure of the periapical lesion through an osteotomy, surgical removal of the lesion, removal of part of the root-end tip, disinfection and, commonly, retrograde sealing or filling of the apical portion of the remaining root canal...
