Research summary
The choice of a restorative material for a broken-down tooth depends on the amount of sound tooth structure remaining. This can influence long term survival of the tooth and/or restoration and the cost involved in rehabilitation.
The restorative materials traditionally used include silver amalgam, gold restorations, dental composite, porcelain and other ceramic materials. A variety of newer materials have been introduced like new generation composites, ceramic and porcelain materials. There are very few clinical studies looking at the clinical performance of these new materials especially on root canal treated tooth.
An interesting observation is that diet that includes almonds, known for its health benefits may be a risk factor for cracked tooth, loss of filling or a broken dental crown. A diet chart may provide information about the risks the diet poses to dental restorations.
With NHS service providing for restorative dental treatment, it is important to base the choice of restorative material and technique for both vital and non-vital teeth based on the best available evidence. We may be able to evaluate the clinical and cost effectiveness of dental crowns on vital and non vital teeth from clinical performance data.
The aim of this study is to investigate the influence of patient related factors, restorative material and tooth related variables on the survival of restorations and the outcome of root canal treatment from retrospective- prospective analysis of data collected from patient records.
This study is based on data collected from patient records of the Department of Endodontics at Guy’s Hospital, London, and at Specialist Dental Practice, 45 Wimpole Street, London. The dental records of about 400 patients treated by the post graduate students during their training and the chief investigator at his specialist practice will be included in the study, collected over a year. Data will be captured using a form from consented patients.
