Safety and Efficacy of a New and Emerging Dental X-ray Modality

Periodic Report Summary - SEDENTEXCT (Safety and efficacy of a new and emerging dental X-ray modality)

1. Publishable summary

1.1 Introduction

The SEDENTEXCT project (1 January 2008 - 30 June 2011) is focused on enhanced safety and efficacy in the use of cone beam computed tomography (CBCT) in dental and maxillofacial radiology. In particular, the work plan aims to find solutions to the challenge of this new X-ray imaging modality becoming available to the large community of dentists, medical physicists and other stakeholders in Europe. It is not only a collaboration of seven partner organisations, but also of experts from different disciplines, including radiologists, medical physicists, dentists, health economists, educationalists and other scientists.

Project objectives

The project has a number of linked objectives:

- To develop evidence-based guidelines on the use of CBCT in dentistry, covering referral criteria, quality assurance and other optimisation strategies.
- To determine patient dose in CBCT, with an emphasis on paediatric dosimetry, and personnel dose.
- To perform diagnostic accuracy studies for CBCT in key clinical applications in dentistry.
- To develop a quality assurance (QA) programme, including the development of a tool / tools for QA and to define exposure protocols.
- To make an economic evaluation ('cost effectiveness' assessment) of CBCT compared with traditional methods of dental imaging.
- To conduct valorisation, both dissemination and training, activities via an open access website.

Each of these objectives is addressed by a work package (WP). In turn, these are planned to interact and feed into the cornerstone WPs of guideline development and valorisation.

1.2 Work performed and results

1.2.1 Management and coordination

The first aspect of any project is its management and coordination. The project has seven partners: the University of Manchester (Uniman) (project coordinator), the National and Kapodistrian University of Athens (NKUA), 'Iuliu Hatieganu' University of Medicine and Pharmacy in Cluj-Napoca (CLUJ), Leeds Test Objects Ltd. (LTO), Katholieke Universiteit Leuven (KULeuven), Malmo University (MAHOD), and Vilnius University (VU).

Financial and administrative management, including quarterly project monitoring, information exchange between project partners and the European Commission and implementation of the consortium agreement and communication action plan (CAP), has been performed by the coordinator (Professor Keith Horner) and project manager (Dr Gillian Armitt) at the Uniman in an efficient manner. Communication between partners is primarily electronic (email or teleconferencing) or by telephone, supplemented by workshops and twice-yearly consortium meetings. An independent ethical monitoring committee was established to oversee ethical approvals and ensure that procedures are being followed. Over and above the financial and administrative management, we have enacted the scientific coordination of SEDENTEXCT as planned in the description of work (DoW).

A project website address, was established and a logo (with colour scheme) developed to define a project identity.

During year 2, the project's publicly accessible website was enhanced, providing a new home page and additional material and functionality. The SEDENTEXCT provisional guidelines for use of CBCT in dental and maxillofacial radiology was published on the project website in May 2009. The site also includes links to the basic principles of CBCT use and national guidance on CBCT. Partners are now able to upload publicly available information about CBCT themselves, as well as upload documents to the project intranet. Apart from acting as a repository for project documentation and material for the WP 1 systematic review, the wiki facilities are enabling partners to brainstorm by contributing to shared web pages.
