Relationship Between Bruxism and Depression: Systematic Literature Review and Meta-Analysis
The International Journal of Prosthodontics
|August 16, 2025
Summary
Individuals with bruxism, including sleep and awake types, have significantly higher odds of experiencing depression. This association remained consistent across various assessment methods and over time, underscoring the need for integrated care.
Area of Science:
- Psychiatry and Behavioral Sciences
- Dental Sleep Medicine
- Epidemiology
Background:
- Bruxism, encompassing sleep and awake types, is a prevalent condition often associated with psychological distress.
- Understanding the link between bruxism and depression is crucial for effective patient management.
- Previous research has yielded varied results, necessitating a comprehensive synthesis of evidence.
Purpose of the Study:
- To systematically review and meta-analyze the association between depression and different classifications of bruxism.
- To examine how assessment methods and bruxism types influence this association.
- To evaluate the temporal trends of this association from 2002 to 2025.
Main Methods:
- A systematic review and meta-analysis adhering to PRISMA guidelines.
- Inclusion of observational studies (cross-sectional, case-control, cohort) in young adults (18-59 years).
- Comprehensive search of PubMed/MEDLINE, Embase, and Brazilian Dentistry Oral Sciences databases.
Main Results:
- Forty-eight articles were included in the review; 26 in the meta-analysis.
- A significant positive association between all types of bruxism and depression was observed (OR=2.84).
- This association remained consistent across diagnostic methods and over time, except for electromyography in sleep bruxism diagnosis.
Conclusions:
- Depression assessment is vital in the multidisciplinary management of sleep and awake bruxism.
- Future studies should clearly differentiate and assess sleep and awake bruxism in relation to depression.
- The findings highlight the importance of considering psychological comorbidities in bruxism patients.

01:18Depression: Overview
336
Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...

01:27Depressive Disorders: MDD and Dysthymia
214
Depressive disorders are a group of mental health conditions characterized by pervasive feelings of sadness, diminished pleasure in life, and a significant impact on daily functioning. These conditions are most prevalent in individuals during their 30s and affect women at twice the rate of men. Contrary to popular belief, younger individuals are generally more susceptible to these disorders than older adults. Two key types of depressive disorders include Major Depressive Disorder (MDD) and...

Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

01:30Stress and Mental Health
211
Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.

349
Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...
