Abstract

The purpose of the study was to assess the current opinions and usage of mineral trioxide aggregate (MTA) for apical barrier formation of non-vital immature permanent teeth by consultants in paediatric dentistry in the UK. A semi-structured postal questionnaire was sent to all known consultants in paediatric dentistry in the UK. The response rate was 78.6% (44 of 56). Thity-eight consultants (86.3%) agreed that the use of this material was a good idea with 68.2% having used or arranged for its use in apical barrier formation. Forty-two consultants (95.5%) agreed that reduced number of visits was an advantage to the technique, with only 34.1% agreeing that this procedure was less likely to weaken the tooth and 63.6% agreed that material and equipment costs were a drawback and 50% agreed that lack of available evidence was a disadvantage to its use. The results from this study give an indication of the extent of MTA use by consultant-led services in paediatric dentistry in the UK and highlights the need for a multi-centre randomised controlled clinical trial.
