The Relationship between Malocclusion and Bad Habits with Signs and Symptoms of Temporomandibular Joint Disorders in USU FKG Students

Introduction

The temporomandibular joint (TMJ) plays a crucial role in the stomatognathic system, which includes teeth, muscles, maxillary and mandibular bones, nerves, blood vessels, periodontal tissue, and joints themselves. This joint enables various complex movements, essential for mastication, manners, pronunciation, and balance of the oral cavity. However, interference with one component of the stomatognathic system can disrupt the function of other components, resulting in an imbalance. One common issue encountered is temporomandibular joint disorder (TMJ), which can be acute or chronic, affecting the head, jaw, face, and neck area.

Causes and Signs of Temporomandibular Joint Disorders

TMJ disorders have multifactorial causes, which can be categorized into three groups: initiation factors, predisposing factors, and speeding factors. Initiation factors include trauma, excessive chewing burden, and bad habits, while predisposing factors include anatomical, systemic, psychological, and malocclusion aspects. Speeding factors are related to psychosocial conditions and hormone metabolism. The signs and symptoms of TMJ disorders vary greatly, including headache, ear pain, joint pain, muscle pain, mandibular deviation, limitations of mouth opening, and joint sounds.

Methodology and Results

This study aimed to analyze the distribution of signs and symptoms of TMJ disorders and examine the relationship between malocclusion and bad habits with these symptoms in students of the Faculty of Dentistry (FKG) of the University of North Sumatra (USU). A descriptive analytic method with a cross-sectional approach was used, involving 112 people as a sample. Data were obtained through interviews and clinical examinations using the Research Diagnostic Criteria (RDC) Procedure Anamnestic Index and Clinical Examination.

The results showed that of the 65 people (58%) who had malocclusion, there were 39 people (60%) who had headache, 50 people (76.9%) had joint pain, 30 people (46.1%) had muscle pain, 50 people (76.9%) experienced mandibular deviation, 49 people (75.4%) experienced limited mouth opening, and 55 people (84.6%) had joint sounds. In addition, based on bad habits, it was found that 55 people (78.6%) had headache, 38 people (54.3%) had joint pain, 39 people (55.8%) had muscle pain, 55 people (78.6%) experienced mandibular deviation, 49 people (70%) experienced limited opening, and 43 people (61.5%) experienced joint sounds.

Analysis and Conclusion

From the results of the analysis, there is a significant relationship between malocclusion and signs of symptoms of TMJ disorders, with each p-value for joint pain (p = 0.001), muscle pain (p = 0.014), mandibular deviation (p = 0.008), limited opening (p = 0.001), and joint sound (p = 0.002). However, there is no significant relationship between malocclusion and headache (p = 0.245). Likewise, there is a significant relationship between bad habits and signs of TMJ disorders, including headache (p = 0.001), muscle pain (p = 0.001), mandible deviation (p = 0.001), and limited opening (p = 0.002). However, bad habits do not have a significant effect on joint pain (p = 0.354) and joint sounds (p = 0.213).

Implications and Recommendations

This study provides an important insight into the factors that contribute to temporomandibular joint disorders, especially among USU FKG students. By understanding the relationship between malocclusion and bad habits of the symptoms of TMJ disorders, it is hoped that preventive measures and more appropriate treatment can be taken. Increasing awareness about the importance of maintaining dental health and good habits in daily life is very necessary to prevent this disorder.

Future Directions

Further studies are needed to investigate the relationship between malocclusion and bad habits with TMJ disorders in other populations, such as children and adults. Additionally, the development of preventive measures and treatment protocols for TMJ disorders should be based on the findings of this study. By doing so, we can reduce the prevalence of TMJ disorders and improve the quality of life for individuals affected by this condition.

Limitations

This study had several limitations, including the small sample size and the use of a cross-sectional approach. Future studies should aim to recruit a larger sample size and use a longitudinal approach to investigate the relationship between malocclusion and bad habits with TMJ disorders over time.

Conclusion

In conclusion, this study highlights the importance of understanding the relationship between malocclusion and bad habits with signs and symptoms of TMJ disorders. The findings of this study provide valuable insights into the factors that contribute to TMJ disorders and suggest that preventive measures and more appropriate treatment can be taken to reduce the prevalence of this condition.
Frequently Asked Questions about Temporomandibular Joint Disorders

Q: What is a temporomandibular joint (TMJ) disorder?

A: A TMJ disorder is a condition that affects the temporomandibular joint, which connects the jawbone to the skull. It can cause pain and discomfort in the jaw, face, and neck, as well as difficulty chewing and speaking.

Q: What are the common symptoms of TMJ disorders?

A: The common symptoms of TMJ disorders include:

Pain and tenderness in the jaw, face, and neck
Difficulty chewing and speaking
Clicking or popping sound when opening or closing the mouth
Limited range of motion in the jaw
Headaches and earaches
Muscle pain and stiffness in the jaw and face

Q: What are the causes of TMJ disorders?

A: The causes of TMJ disorders are multifactorial and can include:

Malocclusion (bad bite)
Bad habits such as teeth grinding or clenching
Trauma to the jaw or face
Stress and anxiety
Hormonal changes
Systemic diseases such as arthritis

Q: Can TMJ disorders be treated?

A: Yes, TMJ disorders can be treated with a variety of methods, including:

Medications to reduce pain and inflammation
Physical therapy to improve jaw mobility and reduce pain
Dental appliances to correct malocclusion and reduce stress on the jaw joint
Surgery to repair or replace the damaged joint

Q: How can I prevent TMJ disorders?

A: You can prevent TMJ disorders by:

Maintaining good oral hygiene and regular dental check-ups
Avoiding bad habits such as teeth grinding or clenching
Practicing stress-reducing techniques such as meditation or yoga
Eating a balanced diet and avoiding hard or sticky foods
Getting regular massages to reduce tension in the jaw and face

Q: Can TMJ disorders be prevented in children?

A: Yes, TMJ disorders can be prevented in children by:

Encouraging good oral hygiene habits from an early age
Monitoring for signs of TMJ disorders such as clicking or popping sounds
Avoiding bad habits such as teeth grinding or clenching
Encouraging children to chew slowly and carefully

Q: Can TMJ disorders be prevented in adults?

A: Yes, TMJ disorders can be prevented in adults by:

Maintaining good oral hygiene habits
Avoiding bad habits such as teeth grinding or clenching
Practicing stress-reducing techniques such as meditation or yoga
Eating a balanced diet and avoiding hard or sticky foods

Q: How long does it take to recover from TMJ disorders?

A: The recovery time from TMJ disorders can vary depending on the severity of the condition and the effectiveness of treatment. In some cases, symptoms may resolve on their own within a few weeks, while in other cases, treatment may be necessary to alleviate symptoms.

Q: Can TMJ disorders be prevented with dental appliances?

A: Yes, dental appliances can help prevent TMJ disorders by correcting malocclusion and reducing stress on the jaw joint. However, dental appliances should only be used under the guidance of a dentist or orthodontist.

Q: Can TMJ disorders be prevented with physical therapy?
