Case complexity of root canal treatments accepted for training in a secondary care setting assessed by three complexity grading systems: A service evaluation.

Aims: To evaluate the complexity of root canal treatments accepted for treatment by postgraduate training grades at Cardiff University Dental Hospital (CUDH) using the English Commissioning Standard for Restorative Dentistry (ECS) in comparison with the American Association of Endodontists case complexity form (AAE) and the Restorative Index of Treatment Need (RIOTN).

Methodology: Two hundred case records were evaluated using the AAE, RIOTN and ECS scoring systems. Each case received a score from minimal to high complexity (1-3).

The Use of 3D Metal Printing (Direct Metal Laser Sintering) in Removable Prosthodontics.

The use of 3D printing is expanding and it is envisaged that it will have an increasing presence within dentistry. Having an appreciation and understanding of such technology is therefore paramount. It is currently used to produce a variety of dental objects/prostheses.

Failure Mechanisms of Fibre Posts: A Literature Review.

Aim: To review the available evidence for the causes of failure of fibre posts.

Materials And Method: A search of MEDLINE was conducted to retrieve available data on fibre posts used for restoration of endodontically treated teeth since 1980. The Cochrane Library was also separately searched for systematic reviews.

Orthodontic extrusion: an interdisciplinary approach to patient management.

Unlabelled: Root fractures that occur at the cervical margin do not always heal predictably, even following a period of splinting. This often leaves margins either sub-gingival or sub-crestal. This provides an unsatisfactory situation for restoring the remaining root as restorations will impinge on the biological width.

Sodium hypochlorite accident--a complication of poor access cavity design.

A case is presented of soft tissue damage resulting from inadvertent injection of sodium hypochlorite through a perforation created during root canal treatment of a mandibular incisor. The importance of access cavity design to help avoid such complications is highlighted and the anatomy of the mandibular incisor is discussed. Measures to minimize the risk of a hypochlorite accident and its potentially serious complications are proposed.

'Double-veneers'--a novel approach to treating macrodontia.

Unlabelled: Macrodontia is a relatively rare but cosmetically challenging dental anomaly with different aetiologies. Where surgical interventions are inappropriate, minimal restorative interventions may be indicated. A case is described of a teenager with macrodontic central incisors who was treated with indirect composite 'double veneers'.
