Abstract
The influence of the breathing mode on the morphology of the dentoskeletal complex has not yet been fully demonstrated. The aim of This an observational retrospective case-control study was to investigate the variables associated with craniofacial developmental features in oral (OB) and nasal breathing (NB) of 1596 patients. Nasal breathing individuals formed the control group and oral breathing study group. Radiographic, clinical data and models were analyzed. Patients were divided into three age groups: 5-12; 13-18; and 19-57 years old. Qualitative data were performed with the chi-square test to identify the associations between the variables examined. Odds ratio tests were performed on the variables, when the results of the x2 tests indicated an association with the "breathing mode" variable with a reliability of 95% and a significance of p < 0.05. The results showed that Class II malocclusion was associated with OB in all age groups. Small jaw and increased lower anterior facial height (LAFH) were associated with OB in patients 5 to 18-years of age, and retruded mandible was associated with OB only in younger patients, the 5-12 year old age group.The conclusion was that dental and skeletal factors, such as Class II malocclusion, small and retruded mandible and increased LAFH supports an association with oral breathing.
