Those who were under 18-years-old, ill or taking decongestant medication were excluded. Her goal was to identify the dental symptoms that divers experience and detect trends in how or when they occur. Of the 41 participants who reported dental symptoms, 42 percent experienced barodontalgia, 24 percent described pain from holding the air regulator in their mouths too tightly and 22 percent reported jaw pain. Another five percent noted that their crowns were loosened during their dive, and one person reported a broken dental filling. “The potential for damage is high during scuba diving,” says Ranna, who has completed 60 dives. “The dry air and awkward position of the jaw while clenching down on the regulator is an interesting mix. An unhealthy tooth underwater would be much more obvious than on the surface. One hundred feet underwater is the last place you want to be with a fractured tooth.” The study also found that pain was most commonly reported in the molars and that dive instructors, who require the highest level of certification, experienced dental symptoms most frequently. This frequency is likely attributed to more time spent at shallower depths where the pressure fluctuations are the greatest, says Ranna. The Professional Association of Diving Instructors has issued more than 24 million certifications around the world. As scuba diving gains popularity as a recreational sport, Ranna hopes to see oral health incorporated into the overall health assessments for certification.
