Summary
Adults with temporomandibular disorder (TMD) show higher depression levels. Depression also increases susceptibility to developing TMD, suggesting a probable link between these conditions.
Area of Science:
- Psychiatry
- Dental Medicine
- Epidemiology
Background:
- Investigating the relationship between mental health and physical conditions is crucial for comprehensive patient care.
- Temporomandibular disorder (TMD) is a prevalent condition affecting the jaw joint and muscles.
- Depression is a common mood disorder with significant systemic implications.
Approach:
- A systematic literature review was conducted using major scientific databases (PubMed, Embase, Web of Science, Scopus).
- Articles were screened in two stages based on predefined eligibility criteria.
- The Joanna Briggs Institute (JBI) critical appraisal tool assessed the risk of bias in included studies.
Key Points:
- Included studies presented a moderate risk of bias.
- Individuals diagnosed with TMD exhibited significantly higher depression scores compared to control groups.
- A bidirectional association was observed, with depression increasing the likelihood of developing TMD.
Conclusions:
- A probable association exists between depression and temporomandibular disorder (TMD) in the adult population.
- Further high-quality research is necessary to definitively establish the causal relationship and underlying mechanisms.

01:18Depression: Overview
316
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
191
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.

01:27Depressive Disorders: Etiology
152
Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.

01:30Stress and Mental Health
195
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.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
