Intravenous cannulation Sharing techniques Sir, in the United Kingdom, peripheral intravenous cannulation using open cannulae is a technique routinely undertaken by dental staff within certain settings, for example hospital wards or dental practices where intravenous sedation is carried out. Successful cannulation takes practice, which can be daunting for inexperienced operators and can result in blood spillage. This is particularly the case when some newer designs of safety cannula (designed to prevent sharps injury) are used, as there can be a need to counteract increased resistance when removing the needle compared to when using older types. This adds further complexity to the procedure and thus increases the risk of blood spillage, which can not only cause a mess, but also a potential contamination risk to those cleaning up afterwards. Disposable dental patient bibs with plastic backs and adhesive tabs for attaching to the wearer's clothing are widely available. Within our sedation clinic, a technique has been devised whereby the adhesive tabs are used to secure the bib to the clothing surrounding the arm proximal to the selected vein prior to cannulation. This means that the bib is held securely in position below the arm, and provides a convenient and reassuring means of protection in case of blood leakage during the cannulation procedure (as shown in Fig. 1). Following the procedure, disposal in the clinical waste is straightforward. We wish to share this practical alternative use of the dental patient bib with your readers, and particularly those who are new to intravenous cannulation.

This case report describes the diagnosis and management of a central giant cell lesion in a young, healthy patient. The article outlines the differences between central giant cell lesions and their counterparts, peripheral giant cell lesions. More crucially, it highlights the challenge in distinguishing these lesions, which are almost identical histopathologically. CPD/Clinical Relevance: This case describes the difficulties that can be faced by clinicians in differentiating between peripheral giant cell lesions and central giant cell lesion. It also highlights the need for specialist multidisciplinary input in managing the surgical and orthodontic implications of these lesions.
