Impact of Attentional Tunelling on a Population of French Practitioners

The tunnel effect, also known as attentional tunnelling, is a cognitive bias affecting all healthcare professionals, including odontologists. It is characterised by an excessive focus on a specific element of a clinical situation, which can alter the overall assessment and lead to errors in medical practice. This poses a particular risk to the quality of dental care, especially surgical care. Despite the importance of this risk, few studies have addressed this issue in dentistry. Therefore, raising the dental community's awareness of this phenomenon on a large scale is both justified and necessary.
