The effect of pressure changes during simulated diving on the pull out strength of glass fiber posts.

Background: Scuba diving is one of the fastest growing sports in the world. The objective of this study was to evaluate the effect of pressure variations to which divers are exposed on the pull out strength of glass fiber post luted with different cements.

Materials And Methods: In this in vitro study, 120 extracted, single-rooted lower premolars were endodontically treated.

Provisional Crown Dislodgement during Scuba Diving: A Case of Barotrauma.

Changes in ambient pressure, for example, during flying, diving, or hyperbaric oxygen therapy, can lead to barotrauma. Although it may seem that this issue was neglected in dental education and research in recent decades, familiarity with and understanding of these facts may be of importance for dental practitioners. We report the case of a patient who experienced barotrauma involving dislodgement of a provisional crown during scuba diving.
