Iatrogenic transmission of vCJD cannot be ruled out as a risk to public health. Dental interventions account for a significant number of invasive procedures performed in primary care. Therefore, it is important to determine the level of risk dental treatments pose in relation to the transmission of CJD. To date published epidemiological studies have relied on reported dental case histories of CJD cases and controls. Little published work has been performed examining the past dental history of CJD cases and controls by direct review of dental records.
The aim of this study was to assess the feasibility of accessing dental records of CJD cases and controls. For this pilot study, we proposed to randomly select 32 CJD ( 8 vCJD & 8 sCJD) cases (4 vCJD and 4 sCJD from England, Scotland, Wales and Northern Ireland) and 24 controls (8 from England, Scotland and Wales), who had consented to have their records accessed and who were registered at the National CJD Surveillance Unit (NCJDSU). Addresses of the dentist treating the cases and controls were obtained from records held at the NCJDSU. For the first part of the study, the dentist was contacted by the research group by letter and then by a follow up phone call. They were invited to submit the patient's records for photocopying and return to the practice. The case records were reviewed by a dental practitioner. The data collected include age at each dental visit, presence or absence of oral disease, types of treatment performed and additional risk factor information, e.g., use of human dura mater graft material.
The first part of the study found that 50% of controls and 22% of cases dental records were available for viewing by contacting the dental practitioner. The major reasons for failing to retrieve patients dental records is due to incorrect details supplied during the initial data collection particularly as the data is supplied by a relative of the case/control. A second stage of the project to assess the feasibility of accessing records via central records held by relevant dental practice boards is on-going.
