Background: Endodontic treatment of root canals or root canal treatment is a frequently performed dental procedure and is carried out on teeth in which irreversible pulpitis has led to necrosis (death) of the dental pulp (nerve). Removal of the necrotic tissue remnants and cleaning and shaping of the root canal are important phases of root canal t...

Background Endodontic treatment involves removal of the dental pulp and its replacement by a root canal filling. Restoration of root filled teeth can be challenging due to structural differences between vital and non-vital root-filled teeth. Direct restoration involves placement of a restorative material e.g. amalgam or composite, directly into th...

This is the protocol for a review and there is no abstract. The objectives are as follows: To provide evidence regarding the effects and long-term results of maxillary distraction osteogenesis compared to orthognathic surgery for the treatment of hypoplastic maxilla in patients with cleft lip and palate. The following aspects will be considered: so...

Background Root canal treatment is carried out on teeth in which irreversible pulpitis has led to necrosis of the dental pulp. As a treatment option it is an alternative to dental extraction. Mechanical preparation and irrigation with antiseptic or antibacterial solutions destroys bacteria and cleans the infected root canal. Irrigants should be eff...
Conference Paper
Objectives: To assess the effectiveness and applicability of endodontic irrigants in general dental practice Methods: We conducted a Cochrane systematic review which described the effectiveness and we now plan to extend the work using the conceptual framework of generalizability to primary care ( Nasser et al Fam Pract 2012; 29 Suppl 1). To imple...

To evaluate in a clinical case series the location of fractured instruments, how many of them could be removed and to compare these findings with the results of a similar study. Within an 18-month period all referred endodontic cases involving fractured instruments within root canals were analysed. The protocol for removal of fractured instruments...

A case is presented where loss of an incisor tooth in a partial denture wearer created an aesthetic emergency. It was not possible to solve this simply by addition of a tooth to the existing denture. Reference to the previous dental history suggested that a further immediate solution might be unwise. The design of the existing denture lent itself t...

The present study describes for the first time the changes of both AEFC thickness and the numerical density of collagen fibers inserting into AEFC at specified levels and sites of human premolars at different stages of development. The investigation was based on 45 premolars (25 maxillary, 20 mandibular; 25 first and 20 second), extracted from adol...
