Burning Mouth Syndrome

Relationship between burning mouth disorder and gastroesophageal reflux disease: A scoping review

OBJECTIVE

This study aims to provide a scoping review and attempts to uncover the possible association between burning mouth disorder and gastroesophageal reflux disease.

METHODS

PubMed, EMBASE, Web of Science, the Cochrane Library, Ovid, Scopus, and a search platform (EBSCOhost) were searched from their inception to August 22, 2023.

RESULTS

After screening 2795 records, 18 articles were included in the final review, comprising cross-sectional studies (n = 9), case-control studies (n = 5), case reports (n = 2), case series (n = 1), and experimental study (n = 1). The prevalence of gastroesophageal reflux disease and its extraesophageal manifestations of laryngopharyngeal reflux in burning mouth patients was reported 3.39%-23.4% and 50%-93.8%, respectively, while oral burning was reported in 9%-45% of patients with gastroesophageal reflux disease. In case-control studies, gastroesophageal reflux disease was more prevalent in patients with burning mouth disorder compared with controls. Burning mouth would be resolved after antireflux therapy in laryngopharyngeal reflux patients in case series. PH value and saliva alternation might be the possible mechanisms.

CONCLUSION

The possibility of the correlation between burning mouth disorder and gastroesophageal reflux disease still needs to be clearly demonstrated through better-conducted studies. The link between them is worth to be explored in future research.

Other Secondary Headaches: Odontogenic Pain and Other Painful Orofacial Conditions

This article discusses extremely common odontogenic pain conditions, which may occasionally present to the neurology clinic mimicking headache, and other uncommon orofacial pain conditions, which may do the same. Typical presentations, investigative strategies, and management are discussed, as well as highlighting key diagnostic criteria and the importance of involving oral or dental specialists where diagnostic uncertainty exists.

Burning mouth syndrome and pelvodynia: A literature review

Burning mouth syndrome (BMS) and pelvodynia are chronic pain still poorly understood and the links between them are all the more so. Health professionals therefore have few resources to understand, diagnose and treat these pains. They may consider and treat these ailments individually, which does not represent optimal care management for the patient and leads to overmedication. This article aims to highlight their contiguity from epidemiological, etiological, diagnostic, and therapeutic perspectives. This study was based on articles which were found using databases such as PubMed and Web of Science. No exclusion criteria were used. Fourteen studies were reviewed. This present work shows that the clinical presentations of these syndromes are similar, as exemplified by their strong association with anxiety and depression. The neurophysiological mechanisms involved in these conditions are similar to those in patients. The diagnosis is essentially based on visual examination and an elimination of all other possible causes. In addition, this work promotes the fact that a common therapy can be implemented when BMS and pelvodynia co-occur. However, the literature on the subject is still very limited. This can be deepened by exploring all the effective treatments in BMS and vulvodynia for penoscrotodynia. Finally, for all these pains, there is a therapeutic order to respect starting with a psychological approach, then topical treatments, systemic therapy and surgical. This therapeutic gradient assists practitioner in their patient's pain management. This article also allows health care providers to quickly find an effective systemic treatment for a patient with both BMS and pelvodynia.

Catastrophising, pain self-efficacy and acceptance in patients with Burning Mouth Syndrome

BACKGROUND

Little is known about pain catastrophising, pain self-efficacy and chronic pain acceptance in burning mouth syndrome (BMS) and their effect on health-related quality of life (HRQoL) and symptoms of anxiety and depressive disorders.

OBJECTIVES

To describe pain catastrophising, pain self-efficacy and pain acceptance in BMS patients and explore associations with affective function and HRQoL.

METHODS

A cross-sectional study of 36 BMS patients (31 female) referred to an Orofacial Pain Clinic completed the Pain Catastrophizing Scale, the Pain Self-Efficacy Questionnaire and the Chronic Pain Acceptance Questionnaire-8 in addition to standardised self-reported questionnaires measuring mood and oral and generic HRQoL.

RESULTS

Pain catastrophising levels were markedly higher than (non-clinical) population norms, with 32.0% of patients reporting clinically relevant levels. Pain self-efficacy and chronic pain acceptance varied widely; 24.0% evidenced low confidence to cope with pain, and 53.8% reported low activity engagement and/or low pain willingness. Catastrophising showed moderate-to-strong associations with measures of anxiety (r = 0.63), depression (r = 0.80), and oral (r = 0.61) and generic HRQoL (rho=-0.84). Self-efficacy and acceptance were also closely related to levels of depression (r/rho=-0.83 to -0.73) and generic HRQoL (r/rho = 0.74 to 0.75). These associations were stronger than those between pain severity and affective function/HRQoL and persisted after controlling for pain severity.

CONCLUSIONS

A substantial proportion of BMS patients evidence maladaptive beliefs about personal effectiveness in managing pain, which is closely related to affective disorders and impaired HRQoL. As such, treatment approaches targeting catastrophising, pain self-efficacy and acceptance may prove beneficial in improving mood and quality of life in BMS patients.

Oral Health Messiers: Diabetes Mellitus Relevance

This article aims to narrate the various oral complications in individuals suffering from diabetes mellitus. Google search for "diabetes mellitus and oral complications" was done. The search was also carried out for "diabetes mellitus" and its oral complications individually. Diabetes mellitus is a chronic metabolic disorder that is a global epidemic and a common cause of morbidity and mortality in the world today. Currently, there are about 422 million cases of diabetes mellitus worldwide. Diabetic patients can develop different complications in the body such as retinopathy, neuropathy, nephropathy, cardiovascular disease. Complications in the oral cavity have been observed in individuals suffering from diabetes mellitus. A study noted that more than 90% of diabetic patients suffered from oral complications. Another research has shown a greater prevalence of oral mucosal disorders in patients with diabetes mellitus than non-diabetic population: 45-88% in patients with type 2 diabetes compared to 38.3-45% in non-diabetic subjects and 44.7% in type 1 diabetic individuals compared to 25% in the non-diabetic population. Oral complications in people with diabetes are periodontal disease, dental caries, oral infections, salivary dysfunction, taste dysfunction, delayed wound healing, tongue abnormalities, halitosis, and lichen planus. The high glucose level in saliva, poor neutrophil function, neuropathy, and small vessel damage contribute to oral complications in individuals with uncontrolled diabetes. Good oral health is imperative for healthy living. Oral complications cause deterioration to the quality of life in diabetic patients. Complications like periodontal disease having a bidirectional relationship with diabetes mellitus even contribute to increased blood glucose levels in people with diabetes. This article intends to promote awareness regarding the oral health of diabetics and to stress the importance of maintaining proper oral hygiene, taking preventive measures, early detection, and appropriate management of oral complications of these patients through a multidisciplinary approach.

Oral burning: local and systemic connection for a patient-centric approach

Burning symptoms in the oral cavity are caused by a range of systemic and local factors, in addition to the neuropathic pain disorder burning mouth syndrome (BMS). Patients may state oral burning as a standalone symptom or may report as a secondary symptom in association with other factors, most commonly with oral dryness, oral mucosal lesions, or certain systemic conditions. There is a level of uncertainty in the presentation of this condition which creates a diagnostic challenge from both the patient's perspective and the practitioner evaluating these individuals. The diagnoses are complicated due to the lack of a clear definition of BMS and clinical guidelines to distinguish BMS from other conditions that are responsible for oral burning symptoms. A clinician should be able to differentiate oral burning from burning mouth syndrome. This integrative review discusses on local and systemic etiologies of oral burning based on current evidence that needs to be excluded for a diagnosis of BMS. It also provides an algorithm for diagnostic workup and therapeutic management to medical providers for patients experiencing oral burning symptoms. This comprehensive system provides a systematic stepwise workup in diagnosing and managing patients presenting with a complaint of oral burning that optimally meets a predictive, preventive, and personalized medicine (PPPM) approach.

Applications of sensory and physiological measurement in oral-facial dental pain

Dentists regularly employ a variety of self‐report and sensory techniques to aid in the diagnosis and treatment of tooth‐related disease. Many of these techniques leverage principles borrowed from psychophysics, the quantitative measurement of the relationship between stimuli and evoked sensations, which falls under the larger umbrella of quantitative sensory testing (QST). However, most clinicians fail to meet the bar for what could be considered quantitative sensory testing, and instead focus on qualitative and dichotomous “yes/no” aspects of sensory experience. With our current subjective measurements for pain assessments, diagnosis and treatment of dental pain in young children and individuals (any age) with severe cognitive impairment rely extensively on third‐party observations. Consequently, the limitation of inadequate pain diagnosis can lead to poor pain management. In this review, it discusses mechanisms that underlie acute and chronic dental pain. It details the measurement of somatosensory responses and pulpal blood flow as objective measures of tooth health and pain. It proposes that bridging these varied methodologies will significantly improve diagnosis and treatment of orofacial pain and pathology. It concludes that improving the precision of sensory measurements could yield important improvements in diagnostic challenges in pulpal pathology for noncommunicative and cognitively impaired individuals.

Burning mouth syndrome in postmenopausal women with self-reported sleep problems

OBJECTIVE

The aim of this study was to investigate possible relationships among hematologic factors, psychological dimensions, the presence of self-reported sleep problems, and clinical characteristics in patients with burning mouth syndrome (BMS).

METHODS

Twenty-five postmenopausal female patients with primary BMS (aged 55.2 ± 9.6 years) were included. All participants underwent clinical and psychological evaluations and blood sampling. The patients were subdivided according to the absence or presence of the self-reported sleep problems.

RESULTS

Pain intensity of BMS patients with sleep problems was significantly higher than those without sleep problems, and the severity of oral complaints was correlated with the presence of depression, anxiety, hostility, phobia, and psychosis. Estradiol levels were significantly lower, and FSH and LH levels were higher in BMS patients with sleep problems than those without sleep problems.

DISCUSSION

BMS patients with sleep problems may suffer inharmonious psychoneuroendocrinological interactions that might worsen oral BMS symptoms.

Burning Mouth Syndrome: Aetiopathogenesis and Principles of Management

Burning mouth syndrome (BMS) is a chronic debilitating oral condition characterised by a burning sensation of the oral mucosa in an otherwise apparently normal person. Its aetiology and pathogenesis are obscure, but both psychogenic factors and peripheral and central neuropathies appear to be implicated. There is no cure for BMS, and treatment with either local or systemic medications focuses on the relief of symptoms and on improving quality of life. In recalcitrant cases, psychological/psychiatric intervention may be helpful. In order to improve treatment outcomes, a better understanding of the pathogenesis of this syndrome might provide a basis for the development of more effective management strategies. In this short review, we discuss current knowledge of the diagnosis, aetiopathogenesis, and management of BMS.

Burning mouth syndrome

Objective

To review the clinical entity of primary burning mouth syndrome (BMS), its pathophysiological mechanisms, accurate new diagnostic methods and evidence-based treatment options, and to describe novel lines for future research regarding aetiology, pathophysiology, and new therapeutic strategies.

Description

Primary BMS is a chronic neuropathic intraoral pain condition that despite typical symptoms lacks clear clinical signs of neuropathic involvement. With advanced diagnostic methods, such as quantitative sensory testing of small somatosensory and taste afferents, neurophysiological recordings of the trigeminal system, and peripheral nerve blocks, most BMS patients can be classified into the peripheral or central type of neuropathic pain. These two types differ regarding pathophysiological mechanisms, efficacy of available treatments, and psychiatric comorbidity. The two types may overlap in individual patients. BMS is most frequent in postmenopausal women, with general population prevalence of around 1%. Treatment of BMS is difficult; best evidence exists for efficacy of topical and systemic clonazepam. Hormonal substitution, dopaminergic medications, and therapeutic non-invasive neuromodulation may provide efficient mechanism-based treatments for BMS in the future.

Conclusion

We present a novel comprehensive hypothesis of primary BMS, gathering the hormonal, neuropathic, and genetic factors presumably required in the genesis of the condition. This will aid in future research on pathophysiology and risk factors of BMS, and boost treatment trials taking into account individual mechanism profiles and subgroup-clusters.
