Investigation of the relationship between stress and temporomandibular joint dysfunction during preclinical and postclinical education among dentistry faculty students at Kütahya Health Sciences University

Key Points

This research aims to explore how stress levels relate to temporomandibular joint dysfunction among dentistry students during different educational stages.
Cross-sectional study conducted with 250 dentistry students from Kütahya Health Sciences University.
Data collected through a 28-item questionnaire, including the Fonseca Anamnestic Index and the Perceived Stress Scale.
Correlation and binary logistic regression analyses performed to assess relationships between variables.
Significant positive correlation between Fonseca Index score and PSS score (r = 0.869, p < 0.05).
Higher stress levels observed in participants with severe temporomandibular disorders.
Postclinical education linked to increased stress levels; significant associations identified for specific demographics.

Abstract

To determine the relationship between the presence of joint dysfunction and stress levels during preclinical and postclinical education in dentistry students. The study was conducted with a total of 250 students, 50 from each year, at Kütahya Health Sciences University’s Faculty of Dentistry. The students were divided into two main groups: the preclinical education and postclinical education groups. The research data were collected via a 28-item questionnaire conducted face to face with the students, consisting of sociodemographic questions, the Fonseca Anamnestic Index, and the Perceived Stress Scale (PSS). The correlation analysis revealed a significant positive correlation between the Fonseca Index score and the PSS score ( r = 0.869, p 0.05). Binary logistic regression analysis showed that postclinical education and PSS scores were significantly associated with TMD. Within the limitations of this cross-sectional study, a significant association was found between TMD severity and perceived stress among dental students. Postclinical education may be associated with higher stress levels.
