ABSTRACT
Objective @# To survey the current situation and analyze the relevant influencing factors of sleep quality in adolescent patients with temporomandibular joint anterior disc displacement. @*Methods@#This study has been reviewed and approved by the Ethics Committee, and informed consent has been obtained from patients. A convenience sampling method was used to investigate 120 adolescent patients with temporomandibular joint anterior disc displacement in the outpatient department of stomatology in a grade A tertiary hospital in Shanghai using the general data questionnaire, the Pittsburgh sleep quality index scale (PSQI), the Chinese middle school student mental health scale (MMHI-60) and the pain visual analog scale (VAS). Descriptive analysis, single factor analysis, correlation analysis and multiple regression analysis were used to explore the relevant influencing factors. @* Results@#The PSQI score of adolescent patients with temporomandibular joint anterior disc displacement in this study was 7.77 ± 4.63. There was a statistically significant difference in sleep quality among patients with different academic pressures and levels of sleep bruxism (P<0.05). The sleep quality score was positively correlated with the pain score (r = 0.45, P<0.001) and positively correlated with the psychological score (r = 0.74, P<0.001). The degree of pain can affect the patient's sleep quality, and those with good mental health have better sleep quality. The results of regression analysis showed that academic stress (OR = 2.511, 95% CI =1.307 ~ 4.828), bruxism (OR = 3.694, 95% CI = 1.394 ~ 9.791), pain score (OR = 2.104, 95% CI =1.095 ~ 4.041) and psychological score (OR = 1.039, 95% CI = 1.021 ~ 1.058) were statistically significant.@*Conclusion @#The sleep quality of adolescent patients with temporomandibular joint anterior disc displacement is generally poor. Academic pressure, sleep bruxism, pain and mental health are the influencing factors of sleep quality.
