Evaluation of sleep quality and chronobiological patterns in bruxism

Bruxism is characterised by repetitive tooth contact and masticatory muscle activity and is further divided into wakefulness and sleep bruxism. The aetiology of the condition is multifactorial, with psychological and genetic factors, as well as the quality of sleep, playing a significant role. This study has been devised to evaluate the existence of chronotype variations, in addition to the relationship that exists between sleep quality and the occurrence of bruxism in individuals who suffer from sleep bruxism. Seventy-six patients diagnosed with bruxism who presented to the otorhinolaryngology, oral and maxillofacial surgery clinics in the last year and 68 patients without a history of bruxism and without clinical findings were involved in the investigation. The Pittsburgh Sleep Quality Index (PSQI) was utilised as a tool to assess the sleep quality of the participants and chronotype characteristics with the Morning-Evening Questionnaire (MEQ). Of the total 144 patients, 83 were female and 61 were male. The study revealed that the sleep quality of the bruxism group was found to be inferior, as evidenced by PSQI scores that were significantly higher (p<0.001). The investigation revealed no statistically significant differences between the groups with the characteristics of chronotype (p>0.05). In individuals with bruxism, no meaningful association was detected between PSQI scores and either gender or chronotype (p>0.05). It is imperative to consider the potential impact of bruxism on sleep quality, as a detailed examination of sleep quality in clinical evaluations is crucial.
