Primary headaches interfere with the efficacy of temporomandibular disorders management

Counselling for patients with a temporomandibular disorder: A scoping review and concept analysis

BACKGROUND

An integral component of comprehensive temporomandibular disorder (TMD) treatment involves what is commonly referred to in literature as patient counselling or patient education. Despite its importance, a clear definition of the concept is lacking.

OBJECTIVES

To describe the concept of counselling (i.e. what is it, what should it consist of, and when should it be given) through a concept analysis of the literature.

ELIGIBILITY CRITERIA

All papers that include a description of counselling or education for TMD are included.

SOURCES OF EVIDENCE

Literature searches were performed in the electronic databases PubMed, Cinahl, and PsycInfo.

CHARTING METHODS

A qualitative analysis was done using the principle-based concept analysis approach, where descriptions of counselling from the included papers were analysed by the researchers.

RESULTS

A total of 71 articles were included. Based on the qualitative analysis of the included articles and descriptions of counselling, the following content themes were identified: (1) general information on TMD; (2) overuse of the masticatory system; (3) posture education; (4) lifestyle and psychosocial factors; (5) exercise- and thermotherapy; and (6) additional information and therapies.

CONCLUSIONS

A definition and framework of counselling for TMD has been provided, which can be used in the clinic, research, and educational programs.

Oral and dental health status in patients with chronic headache

INTRODUCTION

Headache is an illness with high prevalence and adverse effects on quality of life. As oral or dental problems such as pain can trigger or aggravate it, we aimed to investigate and compare oral and dental health status in patients affected with chronic headaches and healthy individuals.

METHODS

The present case-control study included 60 patients with chronic headaches (case) and 60 healthy individuals (control) in Rasht, Iran. The demographic characteristics and clinical examinations, including decayed/missing/filled teeth (DMF-T) and community periodontal index of treatment needs (CPITN) indices, as well as bruxism, frequency of tooth brushing and flossing, and maxillary and mandibular tooth wear were recorded in a checklist. Data analysis was performed using the IBM SPSS version 28 at a significance level of 0.05.

RESULTS

The case group consisted of 25 men (41.7%) and 35 women (58.3%) with an average age of 32.55 ± 6.62 years, while the control group had 27 men (45%) and 33 women (55%) with an average age of 30.95 ± 6.33 years. The study groups were not significantly different in bruxism, frequency of tooth brushing and flossing, DMFT, CPTIN, and maxillary and mandibular tooth wear.

CONCLUSION

It seems that chronic headaches do not significantly affect the oral and dental health of the sufferers. Moreover, it appears that these patients are well aware of the role of oral and dental hygiene in triggering or aggravating the episodes of headaches.

Current thinking in physiotherapy for the management of idiopathic and postsurgical temporomandibular disorders: a narrative review

Temporomandibular disorders (TMDs) are the second most common form of orofacial pain after an odontogenic source. Despite their complex aetiopathology they are considered a musculoskeletal disorder. They can have a significant impact on the quality of life of those suffering from TMDs, but can be treated and managed through a mixture of conservative and surgical approaches. Physiotherapists specialising in musculoskeletal therapy and pain management can offer a variety of techniques to help in the treatment and management of TMDs. In this narrative review the evolution of physiotherapy practice in the United Kingdom will be outlined, along with a discussion about physiotherapeutic theoretical frameworks in the management of musculoskeletal disorders and idiopathic TMDs. Finally, a narrative review will be presented, outlining the literature exploring the use of physiotherapy post TMJ surgery, underpinned by a systematic literature search on the topic. After screening for inclusion in the narrative review, eight articles were included for narrative synthesis. The main findings were that there is a relative paucity of studies looking at the value of physiotherapy post TMJ surgery compared with the treatment of idiopathic TMDs, and there is heterogeneity in the physiotherapy programmes described in the literature, but the addition of physiotherapy post TMJ surgery seems to augment the patient's response to surgery. The article concludes by describing the domestic challenges and opportunities of integrating physiotherapy into TMD management pathways.

Effects on temporomandibular disorder in the treatment of tension-type headache with acupuncture and therapeutic exercises. A secondary analysis from a randomized controlled trial

OBJECTIVES

To examine the effects of acupuncture and therapeutic exercise alone and in combination on temporomandibular joint symptoms in tension-type headache and to evaluate the potential interaction of existing temporomandibular dysfunction on the success of headache treatment.

DESIGN

Pre-planned secondary analysis of a randomized controlled, non-blinded trial.

SETTING

Outpatient clinic of a German university hospital.

SUBJECTS

Ninety-six Participants with frequent episodic or chronic tension-type headache were randomized to one of four treatment groups.

INTERVENTIONS

Six weeks of acupuncture or therapeutic exercise either as monotherapies or in combination, or usual care. Follow-up at 3 and 6 months.

MAIN MEASURES

Subjective temporomandibular dysfunction symptoms were measured using the Functional Questionnaire Masticatory Organ, and the influence of this sum score and objective initial dental examination on the efficacy of headache treatment interventions was analyzed.

RESULTS

Temporomandibular dysfunction score improved in all intervention groups at 3-month follow-up (usual care: 0.05 [SD 1.435]; acupuncture: -5 [SD 1.436]; therapeutic exercise: -4 [SD 1.798]; combination: -3 [SD 1.504]; P = 0.03). After 6 months, only acupuncture (-6 [SD 1.736]) showed a significant improvement compared to the usual care group (P < 0.01). Subjective temporomandibular dysfunction symptoms had no overall influence on headache treatment.

CONCLUSIONS

Only acupuncture had long-lasting positive effects on the symptoms of temporomandibular dysfunction. Significant dental findings seem to inhibit the efficacy of acupuncture for tension-type headache.

Craniofacial disorders and headaches. A narrative review

OBJECTIVES

Craniofacial- and headache disorders are common co-morbid disorders. The aim of this review is to provide an overview of the research discussing craniofacial pain, especially temporomandibular disorders, and its relationship and impact on headaches, as well as suggestions for diagnostic assessment tools and physical therapeutic management strategies.

METHOD

A narrative structured review was performed. A search was conducted in MEDLINE using terms related to craniofacial pain and headaches. Additionally, papers regarding this topic were also extracted from the authors' personal libraries. Any study design (i.e., RCT, observational studies, systematic review, narrative review) that reported the concepts of interest was included, using Covidence. Results were narratively synthesized and described.

RESULTS

From an epidemiological perspective, craniofacial pain and headaches are strongly related and often co-existing. This may be due to the neuroanatomical connection with the trigeminal cervical complex, or due to shared predisposing factors such as age, gender, and psychosocial factors. Pain drawings, questionnaires, and physical tests can be used to determine the cause of pain, as well as other perpetuating factors in patients with headaches and craniofacial pain. The evidence supports different forms of exercise and a combination of hands-on and hands-off strategies aimed at both the craniofacial pain as well as the headache.

CONCLUSION

Headaches may be caused or aggravated by different disorders in the craniofacial region. Proper use of terminology and classification may help in understanding these complaints. Future research should look into the specific craniofacial areas and how headaches may arise from problems from those regions. (249 words).

The Role of Pain Inflexibility and Acceptance among Headache and Temporomandibular Disorders Patients

Temporomandibular disorders (TMD) and headache are complex. This study aims to assess the association between TMD, headache, and psychological dimensions such as psychological inflexibility and pain acceptance. The sample consisted of 120 participants following a non-probabilistic convenience sampling strategy through a direct invitation to the patients attending our facilities and their relatives (n = 61 diagnosed with headache, n = 34 diagnosed with TMD-headache, n = 25 control group). Diagnostic Criteria for Temporomandibular Disorders (DC-TMD), International Classification of Headache Disorders (ICHD-3 beta version), Chronic Pain Acceptance Questionnaire (CPAQ-8), and Psychological Inflexibility in Pain Scale (PIPS) were used as assessment tools. One-way ANOVA, multiple regression analysis (MRA), and the Johnson-Neyman approach were run by IBM SPSS, version 27 (IBM^® Company, Chicago, IL, USA). The significance level was 0.05. One third of our sample presented with headache with TMD. Females were predominant. Males with headache, no systemic disease, less pain severity but higher frequency, living longer with the disease and having sensitive changes, showed higher pain acceptance. When headache occurs with TMD, women with higher education, no headache family history, less pain, and no motor changes showed higher pain acceptance. Patients with both conditions are more liable to have chronic pain and pain inflexibility. Pain intensity and willingness explain 50% of the psychological inflexibility in the headache group. In our sample, individuals suffering from both conditions show greater pain inflexibility, implicating more vivid suffering experiences, leading to altered daily decisions and actions. However, further studies are needed to highlight this possible association.

Temporomandibular disorder and headache prevalence: A systematic review and meta-analysis

Background:

Temporomandibular disorders (TMD) and headaches are prevalent among the global population. Patients often suffer from both conditions, and they are likely to be associated in a bidirectional way. However, the nature of the association remains unclear. Understanding the epidemiological aspects of the relationship between these conditions could have important clinical implications.

Objective:

To evaluate the prevalence of headaches in TMD patients as well as the prevalence of TMD in patients who suffer from headaches.

Method:

A systematic literature search was conducted using electronic databases. Studies published in English and those that used an acknowledged diagnostic criteria for TMD and headaches were included. Study quality was assessed using the Newcastle-Ottawa scale and meta-analyses were performed to generate pooled prevalence estimates.

Result:

Thirty-one studies met the selection criteria for the review; 16 studies evaluated the prevalence of headache in TMD patients and 15 studies evaluated the prevalence of TMD in headache patients. The included studies were of moderate-to-high quality. Meta-analyses revealed moderate-to-large heterogeneities across included studies. Pooled prevalence estimates from meta-analyses indicated similar rates of headaches in TMD patients and of TMD in headache patients (61.58%, 95% CI 45.26–76.66 and 59.42%, 95% CI 51.93–66.60, respectively). Migraines were more commonly observed in TMD patients (40.25%, 95% CI 35.37–45.23) compared to tension-type headaches (18.89%, 95% CI 12.36–26.44). The prevalence of headaches was particularly high in painful-TMD (82.80%, 95% CI 75.41–89.10).

Conclusion:

Despite large variance in prevalence rates across included studies, this review suggests headache and TMD frequently co-occur, particularly in the case of migraines and muscle related TMD. This association has important clinical, pathophysiological and therapeutic implications.

Temporomandibular disorders in patients with polysomnographic diagnosis of sleep bruxism: a case-control study

BACKGROUND

Temporomandibular disorders (TMD) is a collective term that refers to complaints of temporomandibular joint (TMJ) pain, fatigue and/or pain of the craniocervical muscles, limitation of movement of the mandible, and TMJ noises. Sleep bruxism (SB) is a disorder involving rhythmic (phasic) or non-rhythmic (tonic) masticatory muscle activity during sleep and is not a movement disorder or a sleep disorder in otherwise healthy individuals. The present study aimed to support or reject the null hypothesis that there is no association between SB and TMD.

METHODS

The study population was recruited from patients who visited the Artmedica Clinic, Mossoro city, Rio Grande do Norte, Brazil. Patients who underwent polysomnography received information about the research and were invited to participate following the inclusion and exclusion criteria. The study sample consisted of 40 individuals with age ranging from 19 to 76 years. The subjects were administered the questionnaire of the European Academy of Craniomandibular Disorders (AEDC). Those who answered affirmatively to at least one question of the questionnaire were recommended to visit the primary researcher's dental clinic for examination; those who met the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) were evaluated, and their condition was classified into one or more subtypes of TMD. The subjects were divided into 4 groups according to the polysomnographic findings and the responses to the AEDC questionnaire. Of the 40 individuals who answered the AEDC questionnaire and underwent polysomnography, 28 presented with TMD symptoms. The data were expressed as simple frequency and percentage values using statistical software. Values of p < 0.05 were considered to be significant.

RESULTS

The results showed that the frequency of TMD in individuals diagnosed to have SB was 46.4%. According to the DC/TMD of the 28 individuals, the most prevalent TMD subtype was local myalgia (85.7%). Of the total subjects, 32.5% had TMD and SB, 36.4% were males, and in the age range of 31 to 40 years (40%).

CONCLUSION

In this study sample, there was no association between SB as currently defined and TMD, thus confirming previous findings on this topic.

Reduction of headache intensity and frequency with maxillary stabilization splint therapy in patients with temporomandibular disorders-headache comorbidity: a systematic review and meta-analysis

This systematic review and meta-analysis aimed to analyze the effectiveness of maxillary stabilization splint (SS) therapy to reduce headache (HA) intensity and HA frequency in patients with temporomandibular disorders (TMD)-HA comorbidity. Randomized controlled trials (RCTs) using full-arch coverage, hard resin, and maxillary SS therapy were included. Electronic databases, including Cochrane Library, MEDLINE through PubMed, Web of Science, and EMBASE, were searched. The risk of bias was analyzed based on Cochrane's handbook. The search yielded 247 references up to January 28, 2020. Nine RCTs were included at a high risk of bias. The comparison groups included other splints, counseling, jaw exercises, medications, neurologic treatment, and occlusal equilibration. Four studies reported a statistically significant reduction in HA intensity, and five studies reported significant improvement in HA frequency from baseline at 2-12 months in patients with TMD-HA comorbidity treated with a full-arch hard maxillary SS. HA frequency in tension-type HA (TTH) comorbid with TMD diagnoses of myofascial pain (MFP) or capsulitis/synovitis improved significantly with SS than that with full-arch maxillary non-occluding splint (NOS) in two studies. Comparison groups receiving hard partial-arch maxillary splint nociceptive trigeminal inhibition (NTI) showed statistically significant improvements in HA intensity in patients with mixed TMD phenotypes of MFP and disc displacement comorbid with "general HA." Comparison groups receiving partial-arch maxillary resilient/soft splint (Relax) showed significant improvements in both HA intensity and frequency in patients with HA concomitant with MFP. The meta-analysis showed no statistically significant difference in the improvement of pain intensity at 2-3 months with comparison of the splints (partial-arch soft [Relax], hard [NTI], and full-arch NOS) or splint use compliance at 6-12 months with comparison of the splints (partial-arch Relax and full-arch NOS) versus the SS groups in patients with various TMD-HA comorbidities. In conclusion, although SS therapy showed a statistically significant decrease in HA intensity and HA frequency when reported, the evidence quality was low due to the high bias risk and small sample size. Therefore, further studies are required.

Evaluation of Relationship Between Sleep Bruxism and Headache Impact Test-6 (HIT-6) Scores: A Polysomnographic Study

Sleep bruxism (SB) is a masticatory muscle activity during sleep characterized by teeth clenching or grinding and/or bracing or thrusting of the mandible. Morning headache is considered as a common symptom of SB; however, the relationship between SB and headache and its impact on patient's life is not clear. Therefore, the present study aimed to assess the relationship between SB using polysomnography with video/audio recording and Headache Impact Test-6 (HIT-6) scores. SB was evaluated in respondents by single-night diagnostic polysomnography with video/audio recording. The study found that Bruxism Episode Index was similar in the group with significant impact of headache on patient's life (HIT-6 score ≥ 50) and in group with little or no impact (HIT-6 score < 50). A statistically significant positive correlation was observed between bruxism associated with arousal and HIT-6 score (r = 0.51, p < 0.05) and between mixed bruxism and HIT-6 score (r = 0.58, p < 0.05) in the subgroup with phasic bruxism. The results indicated the relationship between SB and impact of severity of headache on the patient's life measured by HIT-6 is only modest. It was also found that the impact of severity of headache measured by HIT-6 is altered only in those with phasic bruxism and is associated with arousal. Further research should elucidate the factors influencing the relationship between SB and headache.

Temporomandibular disorder and headache in university professors

[Purpose] Temporomandibular disorder is a condition with a multifactor etiology that involves the temporomandibular joint, bones, surrounding muscles and facial pain is the most common symptom. This study evaluated the possible association between headache and temporomandibular disorder in university professors. [Participants and Methods] Twenty-seven professors were recruited and answered the Axis II of the Research Diagnostic Criteria for Temporomandibular Disorders for the evaluation and diagnosis of temporomandibular disorder and filled out a “Headache Diary” proposed by the American Headache Society. [Results] The university professors showed headache and temporomandibular disorder, but no association was found between the two conditions. Comparing the gender, the males were most frequently affected, but females had more intensity of signs and symptoms. There is a lack of data on the population addressed in the present study. [Conclusion] Indeed, this was the first such study developed with university professors. It is of considerable importance to develop further studies to investigate the possible association between headache and temporomandibular disorder.

Evaluation of primary headache associated with temporomandibular dysfunction in adolescents from Santos, SP, Brazil: an observational study

[Purpose] Evaluate the association of primary headache and Temporomandibular Dysfunction in healthy adolescents from the Santos, SP, Brazil. [Participants and Methods] A total of 208 adolescents, aged 11 to 16 years old were randomly selected at the dentistry clinic at Universidade Metropolitana de Santos. For that, the Fonseca Anamnestic Index was applied, including information such as: limitation when opening the mouth and moving the jaw, headaches, pain in the temporomandibular joint, noises in the temporomandibular joint, and the habit of tightening or grinding the teeth. The data were submitted to descriptive statistical analysis and the χ² test and Fisher’s exact test were used to evaluate the association of categorical variables. [Results] The results were 63% of male participants, and 61% of female participants had Temporomandibular Dysfunction. In both genders headache was associated with the presence of Temporomandibular Dysfunction, with 93 participants with light headache and 39 with moderate headache. [Conclusion] There was an association between headache and the presence of Temporomandibular Dysfunction, and the percentage of affected males was slightly higher among this association. In the sample of adolescents who presented Temporomandibular Dysfunction, moderate headache was the main reported symptom of both genders.

Chronic Temporomandibular Disorders: disability, pain intensity and fear of movement

Background

The objective was to compare and correlate disability, pain intensity, the impact of headache on daily life and the fear of movement between subgroups of patients with chronic temporomandibular disorder (TMD).

Methods

A cross-sectional study was conducted in patients diagnosed with chronic painful TMD. Patients were divided into: 1) joint pain (JP); 2) muscle pain (MP); and 3) mixed pain. The following measures were included: Craniomandibular pain and disability (Craniofacial pain and disability inventory), neck disability (Neck Dsiability Index), pain intensity (Visual Analogue Scale), impact of headache (Headache Impact Test 6) and kinesiophobia (Tampa Scale of Kinesiophobia-11).

Results

A total of 154 patients were recruited. The mixed pain group showed significant differences compared with the JP group or MP group in neck disability (p < 0.001, d = 1.99; and p < 0.001, d = 1.17), craniomandibular pain and disability (p < 0.001, d = 1.34; and p < 0.001, d = 0.9, respectively), and impact of headache (p < 0.001, d = 1.91; and p < 0.001, d = 0.91, respectively). In addition, significant differences were observed between JP group and MP group for impact of headache (p < 0.001, d = 1.08). Neck disability was a significant covariate (37 % of variance) of craniomandibular pain and disability for the MP group (β = 0.62; p < 0.001). In the mixed chronic pain group, neck disability (β = 0.40; p < 0.001) and kinesiophobia (β = 0.30; p = 0.03) were significant covariate (33 % of variance) of craniomandibular pain and disability.

Conclusion

Mixed chronic pain patients show greater craniomandibular and neck disability than patients diagnosed with chronic JP or MP. Neck disability predicted the variance of craniofacial pain and disability for patients with MP. Neck disability and kinesiophobia predicted the variance of craniofacial pain and disability for those with chronic mixed pain.
