Certified Hyperbaric Technologist Practice Test

How might tooth squeeze be misidentified when it involves the upper teeth?

1. Inner barotrauma

2. Sinus squeeze

3. Barodontalgia

4. Myringotomy

The correct answer is: Sinus squeeze

Tooth squeeze, which is also known as barodontalgia, occurs when there is a differential pressure exerted on the enclosed air space within a tooth, often leading to pain. When this condition affects the upper teeth, it can occasionally be confused with sinus squeeze because both conditions can present similar symptoms, such as facial pain or pressure. Sinus squeeze happens when the sinuses cannot equalize pressure during changes in atmospheric pressure, often felt during ascents or descents in an aircraft. As the upper teeth are located close to the maxillary sinuses, the discomfort felt in the teeth can easily be misattributed to sinus pressure rather than the actual tooth structure itself. In cases of tooth squeeze, the pain may mimic or overlap with that of sinus squeeze, especially if there is inflammation present in the sinus area or if dental issues are exacerbated by pressure changes. This misidentification is significant because both conditions require different approaches for management and treatment—understanding the source of the pain is crucial for effective resolution. Hence, recognizing that signs of tooth squeeze can be mistaken for sinus squeeze highlights the importance of thorough assessment in affected individuals, especially for hyperbaric technologists involved in patient care during pressure changes.
