Case 8 - Painful trismus

In this highly technical and evidence-based episode, we explore "Case 8: Painful trismus" to optimize your preparation for the ADC OSCE exam. Drawing directly from the authoritative source, Odell's Clinical Problem Solving in Dentistry, we dissect the clinical presentation of a 27-year-old female patient presenting with acute, painful limitation of mouth opening (restricted to 23mm interincisal distance) and mandibular deviation to the right. We guide you through the cognitive architecture of formulating a differential diagnosis, defining true trismus as a spasm of the muscles of mastication, while distinguishing between extra-articular causes (like myofascial pain or tetanus) and intra-articular causes. Listeners will learn how to clinically evaluate temporomandibular joint (TMJ) movements, including translation and lateral excursions, to confidently diagnose an internal derangement of the right TMJ presenting as a closed lock (anterior disc displacement without reduction). Tailored specifically for ADC candidates, Australian oral health therapists, and dental students across the world, this episode will strengthen your diagnostic problem-solving skills for complex TMJ presentations.
