#BAROTRAUMA TRAITS MANUAL#

At least one dental barotrauma was reported by 10.1% of respondents, including mainly loss or fracture of a dental filling (4.2%). Most barodontalgia affected posterior (81.2%) and upper teeth (55.2%) with dental filling (50.0%). Barodontalgia was reported by 18.7%, with some respondents reporting more than one episode. RESULTS: There were 684 scuba divers (65.4% men aged 48 ± 12 yr) who participated in the study. It contained questions regarding general characteristics of participants, barodontalgia and dental barotrauma occurrences, and relationship of the diver with his/her dentist. The online questionnaire was distributed from October to December 2020. METHODS: A nationwide cross-sectional internet-based survey was conducted among French scuba divers over 18 yr of age registered by the French Federation of Underwater Sports (FFESSM). The aim of this study was to investigate the occurrence of barodontalgia and dental barotrauma among French civilian scuba divers. Barodontalgia refers to oral pain resulting from a change in ambient pressure. INTRODUCTION: Barometric pressure variation during dives may induce barodontalgia and barotrauma. This leads to incomplete information, especially concerning the preventive means available to divers. Despite awareness rising, there is a lack of recourse to the dentist. In conclusion, oral problems in scuba diving represent frequent events that can compromise the safety of divers. Among respondents, 43.5% completed a dental examination before a diving season and showed fewer oral problems during their scuba diving practice than those who did not. High diving level was associated with more frequent barodontalgia (17.5%), gum pain (7%) and barotrauma (7.6%). The prevalence of dental fractures increased significantly with age. Mouth syndrome was more frequent among women (18.6%) and divers aged between 18 and 34 years (18.9%). As results, oral manifestations were experienced by 25.2% of the divers, including barodontalgia (10.8%), mouth syndrome (13.4%), gum pain (2.8%) and dental fractures caused by barotrauma (3.7%) or shocks (1.9%). Data from 1015 French civilian divers were collected via a nationwide online questionnaire in which participants indicated information concerning orofacial experienced problems during their diving activity, and their medical preventive habits. The aim of this study was to assess the prevalence of these problems and to analyze civilian divers' behavior about their dental prevention in France, via a cross-sectional study. It can cause orofacial problems, mostly linked to pressure changes. Self-contained underwater breathing apparatus (SCUBA) diving is becoming widely democratized among hobbyist practitioners. RMGI is considered suitable and is not influenced by hand-mixing or barometric pressure changes.

When treating patients frequently exposed to hypobaric environments, automixing of ZP would seem favorable, while manual mixing should be avoided. Automixed ZP (931.9 ± 134.4 N in flight 996.0 ± 107.4 N on the ground) and RMGI subgroups (ranging from 581.0 N ± 114.3 N to 662.4 N ± 92.5 N) were not affected by hypobaric conditions. Hand-mixing of ZP resulted in a significant reduction of mean (± SD) retention forces (581.6 ± 204.5 N) when compared to the control group on the ground (828.4 ± 147.9 N). All cemented crowns were stored in climatized boxes during the experimental phase. The cemented crowns of the 4 × 2 subgroups were either kept on the ground or were transported in an aircraft at altitudes up to 13,730 m (45,045.9 ft N = 28 each), thus being subjected to the pressure changes (80×) every aircrew member or frequent flyer is exposed to. 1) A zinc phosphate cement (ZP), and 2) a resin-modified glass ionomer cement (RMGI), each mixed either A) manually or B) by means of automix capsules, were used for cementation. There were 56 implant abutments supplied with CAD/CAM milled zirconia oxide crowns. The objective of this study was to provide data on the retentive characters of two cements commonly used on implant abutment surfaces both under normal and under hypobaric conditions. There is only scant information on the influence of the hypobaric environment on luting agents and their efficacy on dental crown cementation.
