“…However, the extent of compliance with recommended procedures in general practice and the effectiveness of the procedures is generally not known, although in some cases the lack of compliance has been demonstrated -studies by Bagg et al (2001 and2007) indicated that compliance with recommended practice in cleaning dental instruments was poor in a number of surgeries, indicating a need for better education of clinicians and nursing staff. The results from this study showed that before use, approximately 40 % of units were contaminated and after they had been used in the clinic approximately 64 % were contaminated.…”

Peer reviewed article isible light units (LCU) used in routine dentistry to cure light activated materials may become contaminated with oral micro-organisms. This pilot study was designed to investigate whether the fan, handle and base unit mains on/off button areas of three different designs of quartz tungsten halogen LCUs (3M Unitek 2500, Elipar Highlight, Demetron Optilux 401) were effectively disinfected after use in a dental teaching hospital. Over a period of seven days 52 LCUs were swabbed before clinics in the morning and 28 were swabbed again after clinics in the afternoon. Bacterial contamination was detected on approximately 40 % (20/52) of units before use and 64 % (18/28) after use: few viable organisms were detected on the fan or handle areas, but many were isolated from the mains button, including Staphylococus aureus . These fi ndings highlight the need for greater awareness of the potential risk of contamination of the base unit and compliance with recommendations to clean and disinfect all areas of the units. Figure 1. Use of a light curing unit in dental restoration. The whole length of the light guide may enter the patient's mouth, depending on the location of the treatment site. The model illustrated is an Elipar Highlight (as in Figure 2A ). The "concertina" style fan or "nose cone" containing the fan in other designs can brush against the corner of the patient's mouth and become contaminated directly by saliva in that manner Abstract V

Mots clés : maladie de Creutzfeldt-Jakob / hygiène / prévention Résumé -Les maladies à prions ou encéphalopathies spongiformes subaiguës transmissibles (ESST) sont des maladies neurodégénatives dont l'issue est fatale. Il n'existe aucun test diagnostique fiable ni aucun traitement. Elles représentent de ce fait une préoccupation pour les professionnels de santé, en particulier pour la prévention de leur transmission. Les tissus dentaires, notamment la pulpe dentaire richement innervée et le tissu gingival, sont des tissus définis comme à faible risque d'infectiosité même, si à ce jour, aucun lien d'iatrogénie par la réalisation d'actes bucco-dentaires n'a été établi. La prise en charge d'un patient suspect de maladie de Creutzfeldt-Jakob sporadique dans le service de Médecine et Chirurgie buccales a nécessité la mise en place d'une organisation adaptée pour prévenir toute contamination et pour assurer la protection des professionnels de santé. Elle a été l'occasion de faire une mise au point sur les textes réglementaires et leur évolution. Lors de la prise en charge d'un patient pour la réalisation d'un acte bucco-dentaire, la prévention repose essentiellement sur l'évaluation du risque lié à la transmission de l'agent infectieux des EST et sur le respect scrupuleux des procédures d'hygiène et de stérilisation à appliquer pour l'unit dentaire et les dispositifs médicaux. Key words:Creutzfeldt-Jakob disease / hygiene / prevention Abstract -Focus on prions transmission risk in the care of a patient with suspected sporadic Creutzfeldt-Jakob disease. Prion diseases known as transmissible spongiform encephalopathies (TSEs) are neurodegenerative diseases whose outcome is fatal. There is at present no reliable diagnostic test and no available treatment. They represent therefore major concern for health professionals with regard to prevention of their transmission. The dental tissues, including the richly innervated dental pulp and the gingiva, are tissues considered to have low risk of infectivity although to date no links with dental procedures has been established. The management of one patient with suspected sporadic Creutzfeldt-Jakob disease (CJD) in the department of Oral Surgery necessitated the establishment of a structure adapted to prevent contamination and to protect health professionals. It was an opportunity to refocus on the official guidelines and their evolution. Prevention during dental procedures is essentially based on two factors: risk assessment of transmission of CJD and strict adherence to hygiene procedures and medical devices sterilization.La prévention du risque infectieux au cours de la réalisa-tion des actes de soins en médecine bucco-dentaire fait partie intégrante de la démarche des professionnels de santé.

“…Dental care faces a number of pragmatic issues. Studies carried out clearly demonstrated that decontamination in dentistry is often not given the consideration or investment that it requires (71,72) . In many cases decontamination in dental clinics is carried out in the same room as where the patient is treated.…”
