The relationship between facial morphology and jaw function remains controversial. The purpose of this study was to investigate differences in self-reported oral behaviour habits between individuals with normodivergent and hyperdivergent facial types. Some 80 cases and controls were individually matched on age, sex ethnicity and treatment stage. The participants were recruited from an orthodontic clinic, and included both adolescents and adults. Habitual oral activity was assessed using the Oral Behaviour Checklist (OBC) based on their experiences in the past 4 weeks. Univariate and bivariate analyses were performed. The sample had a mean age of 17·2 years (SD = 4·6; range = 12-49 years), and was predominantly female (65·0%) and of New Zealand European origin (91·3%). The prevalence of reporting one or more frequently performed habitual muscular behaviour in either study group was over 85% (P > 0·05). There was no difference in total OBC score between the hyperdivergent (25·6; SD: 9·0) and normodivergent group (25·3; SD: 9·9). Moreover, there was no difference in the prevalence of either nocturnal or daytime oral behaviours between the two groups. While this study did not include any objective measures of functional or habitual activity, we found no differences in self-reported oral behaviour habits between normodivergent and hyperdivergent individuals. The findings do not support an association between vertical facial form and habitual muscular activity.
面部形态与颌功能之间的关系仍存在争议。本研究的目的是调查面部类型为平均生长型和高角型的个体在自我报告的口腔行为习惯上的差异。约80例病例和对照在年龄、性别、种族和治疗阶段进行了个体匹配。参与者从正畸诊所招募，包括青少年和成年人。根据他们过去4周的经历，使用口腔行为检查表（OBC）评估习惯性口腔活动。进行了单变量和双变量分析。样本的平均年龄为17.2岁（标准差=4.6；范围=12 - 49岁），主要为女性（65.0%），且为新西兰欧洲裔（91.3%）。在任何一个研究组中，报告一种或多种频繁进行的习惯性肌肉行为的患病率超过85%（P>0.05）。高角型组（25.6；标准差：9.0）和平均生长型组（25.3；标准差：9.9）的OBC总分没有差异。此外，两组之间夜间或白天口腔行为的患病率也没有差异。虽然本研究没有包括任何功能或习惯性活动的客观测量，但我们发现平均生长型和高角型个体在自我报告的口腔行为习惯上没有差异。这些发现不支持垂直面部形态与习惯性肌肉活动之间的关联。
