The term "barotrauma" is used to describe a physical injury caused by a rapid or extreme change in air pressure. Enclosed areas within the body are particularly affected by barotrauma.


A 40-year-old man had complaints of restorations in three teeth fracturing and dislodging while he was scuba diving at a depth of 35 meters. The affected teeth contained carious dentin. The caries was removed, and the affected teeth underwent endodontic, restorative and prosthetic rehabilitation.


Inadequate restorations and selection of dental materials in some cases predispose patients to barotrauma. To prevent barotrauma-related damages on the teeth, it is important to maintain good-quality restorations and avoid trapping air beneath them. Dentists and patients who are exposed to barometric stress as part of their jobs or hobbies should know the causes of barotrauma and be aware of the importance of routine dental checkups to avoid barotrauma-related dental problems.
