The term ‘bioactive materials’ covers a range of similar calcium silicate-based materials that are not only biocompatible but promote healing and regeneration of tissues. The most notable examples of...

If the coronal structures are largely intact (particularly marginal ridges) and loading is favourable, a simple plastic restoration can be placed in the access cavity. Placing a bonded restoration...

The first stage in root canal retreatment is the careful assessment of and, if necessary, the removal of existing restorations to access the canal system. Attempting retreatment through an existing...

Many materials and techniques are available to obturate the root canal system. Grossman et al have described the properties of an ideal obturation material (Table 1),4 however, no single material can...

During endodontic treatment mechanical debridement alone will not rid the root canals of bacteria,1 regardless of whether this is done by hand files or rotary instruments.2 First, instruments do not...

The majority of micro-organisms are in the coronal portion of the canal and pulp chamber.4 Thus, whatever instruments are used, a crown down approach and only initial scouting of the canal prior to...

Accessing the root canal system can be one of the biggest challenges to successful root canal treatment. The ability to get instruments into the canal system unimpeded using a glide path without...

Dentists are often asked by patients, ‘Will it work?’ and it falls to the dentist to give an indication as to the projected success rate of their treatment. The definition of success has been a topic...

This paper has summarized the various techniques available to optimize endodontic irrigation, either through manually activating syringe irrigation or through using contemporary automated devices....

A 23-year-old Caucasian female patient was referred by her general dental practitioner to a University teaching hospital. She reported hypersensitivity to hot and cold stimuli in relation to LR4..

The aim of endodontic treatment, or retreatment, is to reduce the microbial load within the root canal system sufficiently to enable the host response to favour periapical healing.1 According to...

Data collection forms were e-mailed to Restorative Specialist Registrars from all 16 dental schools across the UK and Republic of Ireland asking for details of the institution's treatment regimes...

More recently, studies are being undertaken on lowering the pH of NaOCl in order to improve its properties.84 This can be accomplished by the addition of chemicals such as etidronic acid...

Peri-radicular surgery is indicated in situations when repeat orthograde endodontic treatment is not possible or may put a tooth at risk of irreparable damage. In 2001, The Royal College of Surgeons...

The files were operated at 250 rpm..
