Document structure and format:


I. Introduction


This research paper examines the relationship between personality traits and bruxism, defined as the grinding or clenching of teeth while asleep. The study investigates whether there is an association between Neuroticism-related traits and teeth grinding. The research is significant as bruxism has various negative consequences, ranging from sore jaw, facial pain to hearing loss and temporomandibular joint disorder.


II. Methodology


The study uses a cross-sectional design with participants drawn from the Baltimore Longitudinal Study of Aging. Data is collected through comprehensive oral examination by a dentist and participants completing personality and dental history questionnaires. The study analyses the correlations among subjective measures, dentist-assessed measures, and psychometric measures using logistic regression.


III. Results


Individuals with Neuroticism-related traits are associated with self-reported grinding, and other oral complaints often associated with anxiety and stress. However, these traits are not associated with more general oral health complaints or dentist-assessed occlusal wear or tongue indentations.


IV. Discussion


The results suggest that individuals high in Neuroticism-related traits tend to grind or clench their teeth more than individuals low in such traits. The study highlights the relationship between negative emotions and bruxism, which could inform treatment options for bruxism and other related oral health concerns. However, the study has limitations in terms of generalizability and use of self-reported measures.


V. Conclusion


This research paper provides evidence for the association between neuroticism and bruxism and other stress-related oral health symptoms. The study has implications for understanding the relationship between personality traits and bruxism, which might inform the development of prevention and treatment interventions for bruxism. However, future research could use more objective methods of measuring oral health to supplement self-reported data.
