Craniofacial growth pattern has been correlated with variations in size of the upper airway spaces. The objective of this study was to evaluate the nasopharyngeal, oropharyngeal, and hypopharyngeal airway spaces variations according to the craniofacial growth pattern, by comparing brachyfacial, mesofacial, and dolichofacial in Angle Class I individuals. To measure the spaces, 45 lateral teleradiographs were used and divided into 3 groups per the craniofacial growth pattern, determined by the Tweed cephalometry angular measurements: FMA and Y-axis. To evaluate the airways, sleep apnea cephalometry was used, containing 28 points that compose 14 factors. Three groups were compared relative to each of the 14 sleep apnea cephalometry measurements. Adherence test to the normal curve was performed. For the non-normally distributed data—measurement of the inferior pharyngeal space—the Kruskal-Wallis test was used for comparison between the groups. For the remaining data, the distribution was normal and ANOVA test was used. Statistically significant difference was verified among the groups for the measurement of the median posterior-palatal space, with the difference being pointed out by the post hoc test between the brachyfacial and dolichofacial groups. For the other measurements, there was no statistically significant difference. It could be concluded that there was difference in the median posterior-palatal space measurement, in the oropharynx region, which was reduced for individuals with a dolichofacial pattern.

Objective: The aim of this study was to associate the presence of oral habits with anxiety and malocclusion. Methods: Cross-sectional observational study with 199 schoolchildren 6–14 years old. Malocclusion was evaluated by using the Index of Orthodontic Treatment Need (IOTN). Oral Habits Questionnaire and Hospital Anxiety and Depression Scale (HADS) were used to assess oral habits and anxiety. The schoolchildren were divided into two groups: mixed and permanent dentition. The associations between the outcome variable (oral habits) and the independent variables (anxiety and malocclusion) were evaluated using the Exact Fischer test and the Chi square test. Results: Of the individuals with malocclusion in permanent dentition, 77.4% reported some deleterious oral habit, and 55% of those with no malocclusion at this stage had deleterious habits. Discussion: Oral habits may be associated with the presence of malocclusion in different stages of occlusal development (mixed and permanent dentition) and may be influenced by anxiety.
