Abstract

Purpose comprehend the respiratory characteristics of individuals with dentofacial deformities and verify if there are differences comparatively to individuals with dentofacial balance. Methods participated 60 individuals (18 to 40 years old), 30 with a dentofacial deformities and 30 of a control group. The assessment of the Maximum Phonation Time for the emissions /a/, /i/, /u/, /s/, /z/ and the number counting was evaluated using the program Sound Forge (Sony); the vital capacity and pneumophonic coordination by the PonyFx spirometer. The results were compared by using the “t” Student test. Results the individuals with dentofacial deformities presented lower Maximum Phonation Time values than individuals with dentofacial balance in the emissions: “s” for those with skeletal Class II malocclusion and men; “z” for individuals with Class II malocclusion; number counting for men. The measures extracted by the spirometry were similar between the individuals with and without dentofacial deformities. Conclusion there were no differences regarding the vital capacity and pneumophonic coordination, but the dentofacial deformities group presented lower values of Maximum Phonation Time in the emissions that contain consonant phonemes.
