Abstract
Introduction: The different types of barodontalgia are clinical-nosological entities which are highly characteristic of the military environment whose physiopathology and treatment are at present still very controversial. Objectives: To describe the dentin-pulp response of the healthy tooth in a Beagle dog model with or without amalgam and composite resin restorations in a hypobaric environment. Material and methods: The study was performed on 308 Beagle dog teeth, which were divided in 3 groups (absence of restorations, amalgam restorations and composite resin restorations) and subjected to a hypobaric change in a low pressure ETC/APTFIOM chamber, applying military simulated standard flight features (OTAN STANAG 3114) and comparing the results to those of a non-flying control group. A histological evaluation was performed after two time periods (3 hours and 21 days) following the ISO/TR7405 guidelines. Results: According to the microscopic study carried out immediately (3 hour) after baro-trauma, the hypobaric changes produced during the simulated flight induced significant (p<0,05) histological pulp responses; however, there were no differences between the teeth restored with different material and the unrestored ones. Also, the observed changes disappeared when the histological evaluation was carried out after a latency period of 21 days Conclusions: There are histological differences in the dentin-pulp response of dog teeth after a simulated flight with regard to a non-flying control group, but the response is similar whether they are restored with amalgam or composite resins or not. All the morphological changes observed are reversible with time.
