“…3,4 Numerous studies have reported a high incidence of fracture in endodontically treated maxillary premolars. 2,5,6 Susceptibility to fracture is the result of the loss of marginal ridges and the pulp chamber roof during access preparation 2,7,8 and is a concern, particularly in maxillary premolars, because their anatomy facilitates separation of the cusps during mastication. 9 Fractures in the unsupported tooth structure can lead to restorative difficulties and even extraction if the tooth is unrestorable.…”

Combined composite-amalgam for cuspal coverage of endodontically treated premolars was similar to direct composite coverage in strengthening restored teeth; however, composite onlay had the highest fracture resistance. SUMMARYThis in vitro study investigated the fracture resistance of teeth restored with combined composite-amalgam for cuspal coverage compared to direct coverage with composite (with or without an amalgam base) and composite onlay. Seventy-two intact maxillary premolars were randomly divided into six groups (n¼12). The two control groups were G1, intact teeth (negative control), and G2, mesio-occlusodistal preparation only (positive control). Each of the four experimental groups used a different type of restoration for the prepared teeth: G3, direct composite cusp coverage; G4, composite onlay; G5, direct composite coverage with an amalgam base; and G6, combined compositeamalgam cuspal coverage. After thermocycling, fracture strength was tested. The data were analyzed with analysis of variance and the least significant differences post hoc tests (a¼0.05). Mean fracture resistance in the six

-Objectives:Primary aim is to quantify the success rate of periapical surgery. Secondary objectives include the determination of the histological nature of the lesions, and the incidence of the different teeth on which this surgery is performed. Study design: This is a prospective cohort study conducted in one centre. The same operator following a standardized surgical protocol performed all surgeries. Follow-up (including clinical examination and periapical X-ray) was conducted at day 7, and months 6, 12 and 18. Statistical analysis included determination of the mean, standard deviation and paired two-tailed Student's t-test, for each of the variables. Results: 132 periapical surgeries were performed on 114 patients. Success and failure rate at 18 months, are 90%, and 6%, and uncertain in 4%. Histopathology confirmed that 72% of the lesions were granulomas, and 28% cysts. Periapical surgery pertains mostly to maxillary (70%) and posterior teeth (70%). Conclusion: Prognosis of conventional periapical surgery is very good. Failure rate peaks at 7 months, written informed consent is paramount.A radiolucent apex after endodontic treatment is a common finding with up to 45% of the treated teeth in certain studies [1,2]. These lesions can be found during a routine check-up, or during an emergency appointment when associated with pain. As orofacial pain is ascribed to periapical abscesses in 25% of the patients [3], these periapical radiolucencies, in the context of periapical surgery, can be a diagnostic challenge. Periapical abscesses are the consequence of a bacterial infection of the root canals [4]. Treatment classically consists of the elimination of necrotic and infected tissue, followed by obturation of the root canal system and a sealed restoration of the crown. Periapical surgery is indicated when root canal retreatment has failed or is contraindicated [4]. An osteo-mucoperiosteal flap followed by the appropriate osteotomy allows access to the apex of the tooth. The lesion is removed and the root canal system sealed [4]. Success rates reported vary between 40% [5] and 97% [6]. Correspondence: alpalantar@wanadoo.fr The main objective of this study is to assess the success rate of periapical surgery using a standardized protocol. Secondary objectives include the determination of the histological appearance of the lesions (granulomas or cysts), the incidence of the different teeth on which this surgery is performed, and the recurrence frequency.

Restoration of the root-filled tooth: pre-operative assessment

This is the first in a series of four papers related to the management of root canal treated teeth. When teeth compromised by extensive restorations become non-vital, suggestions have been given as to how root canal treatment can be carried out with the greatest chance of success. Once root canal treated, either by a previous dentist or by the current dentist, a review of the assessment process that should be carried out prior to placing costly indirect definitive restorations is given. It will be clear that post-retained restorations are mainly reserved for anterior or single-rooted teeth, posterior teeth rarely requiring a post for core retention. The second paper in this series describes the basic tooth preparation that should be carried out prior to placing a post. Depending on the type of post system used, further modifications to tooth preparation may be required and the cementation techniques may also have to be modified. The third paper therefore discusses the various post types, when and how they should be used for optimum results. The final paper addresses reinforcement and restoration of compromised root canals, such as those with immature, open apices, or those that have been over-prepared for previous post-retained restorations.
