Imagine the following situation: After the administration of local anesthesia on the alveolar nerve, a patients reports dizziness, itching and starts coughing. How would you react in this situation? Or another situation: One month after the provision with a fixed partial denture, a patient returns to your office and claims that he is now suffering an allergic reactioin against gold alloys. What would you reply? Learn from Dr. Matthias Troeltzsch about the differential diagnosis of ostensible allergic reactions.
Patients with allergies to dental materials or drugs are a challenge in everyday practice. Learn about the treatment of allergic patients which is a special challenge for the clinician and requires detailed knowledge.
Dr. Matthias Troeltzsch presents the basic knowledge necessary to understand the pathophysiology of the allergic reaction. The course also discusses important allergies, the management of allergic emergencies and explains the clinical diagnosis of allergy-related problems.
While polymethyl methacrylates and latex can trigger delayed immunological reactions in the form of a contact allergy, sodium metabisulphite (an antioxidant found in local anaesthetics), penicillin and nickel are the most common causes of immediate systemic reactions. These can range from restlessness and headaches, to nausea and breathing difficulties, through to anaphylactic shock, and may require urgent emergency treatment. In this respect, Dr. Trötzsch stresses the importance of contacting emergency medical services without undue delay, and of doing so in good time irrespective of any concerns regarding an incorrect diagnosis that one might have made. The consequences of failing to provide appropriate assistance would be far more serious.
According to Dr. Tröltzsch, there is little point in attempting to identify visible and unmistakable signs of an allergy in the oral cavity. Oral mucosal diseases such as lichen planus (and the associated buccal Wickham striae), lingua geographica or even mechanically irritated areas of mucosa cannot be clearly distinguished from immediate allergic reactions that are visible on the mucosa.
