Tetanus of suspected dental causality

Tetanus infection by Clostridium tetani is a major health problem in many developing countries, including India. Significant morbidity and mortality is attributed to lack of awareness, hygiene and incomplete vaccination. The most common cause of tetanus infection follows cutaneous injury or infection. However, a localized point of entry cannot always be determined. Tetanus has been associated with tooth extraction, root canal therapy, gross caries, periodontal abscess and intraoral soft tissue trauma. The classic symptoms of trismus and risus sardonicus may result in an initial presentation to an oral and maxillofacial surgeon. Due to the rarity of this infection, the dentist or the health care provider may fail to corroborate the findings and be unsuspecting of the diagnosis. Prompt recognition is the key in such a scenario due to the inherent risk of rapid progress of symptoms, progressive deterioration of the health condition and catastrophic complications. A sound knowledge of the effects of tetanospasmin, the disease process, prevention and vaccination against tetanus with its management is essential for health care workers. The authors hereby present a case of tetanus with a suspected dental etiology to make the dental fraternity aware of this lurking malady.
