To assess the relationship between psychoemotional state and signs of oral cavity occlusal and nonocclusal parafunctions, together with masseter muscle tone, in undergraduate dentistry students.
The study population comprised first and fifth grade dentistry students who were investigated using psychological and health questionnaires, and stomatological examination with electromyography of the masseter muscles. Differences in variables between first and fifth grade students were analysed using Student’s -test or χ-test and Pearson’s correlation coefficient was used to analyse associations between variables.
A total of 113 students (52 first-grade, mean age 20 years; and 61 fifth-grade, mean age 23.6 years) were included. Older age was associated with lower level of perceived stress and anxiety. Moreover, a significant positive relationship was observed between level of perceived stress and anxiety and tone of both masseter muscles.
Increased psychoemotional burden and increased rates of experienced anxiety were associated with growth of masseter muscle tone in this study population.
评估口腔医学专业本科学生的心理情绪状态与口腔咬合及非咬合副功能体征以及咬肌肌张力之间的关系。
研究对象包括一年级和五年级口腔医学专业学生，通过心理和健康问卷以及咬肌肌电图口腔检查对其进行调查。使用学生 t 检验或χ检验分析一、五年级学生变量之间的差异，并使用皮尔逊相关系数分析变量之间的关联。
共纳入113名学生（52名一年级学生，平均年龄20岁；61名五年级学生，平均年龄23.6岁）。年龄较大与感知压力和焦虑水平较低相关。此外，在感知压力和焦虑水平与双侧咬肌肌张力之间观察到显著的正相关关系。
在该研究人群中，心理情绪负担增加和焦虑发生率增加与咬肌肌张力增加有关。
