Burning mouth in oncology care: a systematic review

Burning mouth, also referred to as oral dysesthesia, is an underreported condition among cancer patients that may represent an early symptom of cancer or an adverse effect of treatment. This review sought to characterize this symptom in oncology care where burning symptoms may occur. A systematic review of the literature was performed based on the PRISMA statement, and the protocol was registered at PROSPERO database. A structured search was done using eight databases. The process of study selection was conducted in two distinct phases. The JBI Critical Appraisal Tools were utilized to evaluate the risk of bias in the studies included. Of the total number of studies assessed, sixteen met the eligibility criteria. Of these studies included, 7 were case reports, 7 cross-sectional studies, and 2 non-randomized clinical trials. Most studies presented low risk of bias (n = 9), while the remaining studies were evaluated and scored as moderate (n = 5) or high (n = 2) risk of bias. Burning mouth was reported as a first symptom of cancer in three studies, and as an adverse event of radiotherapy (n = 2), chemoradiotherapy (n = 2), and chemotherapy (n = 9). Burning mouth was a first symptom in 0.62% of oral squamous cell carcinoma (OSCC), and 3.3% of patients with pain as chief complaint. Oral dysesthesia prevalence was 13.6% in patients experiencing chemotherapy-induced oral adverse events. The symptom of burning mouth should be examined in oncology care, as it may be underreported and therefore undertreated. New therapies may be related to a higher risk of oral burning and studies assessing approach to management are needed. Current management borrows from the current management of burning mouth in the non-cancer setting.

Oral dysaesthesia: a special focus on aetiopathogenesis, clinical diagnostics and treatment modalities

Oral dysaesthesia is a condition characterised by persistent alteration to oral sensation, perceived by the patient to be abnormal and/or unpleasant, in the absence of any mucosal pathology. The condition can be difficult to detect and diagnose. A possible peripheral or central neuropathic aetiology has been proposed. Burning mouth syndrome (BMS) is the most common idiopathic oral dysesthesia in which long-term suffering is often reported by patients. Recent efforts from professional organisations and study groups have provided a consensus on BMS disease definition and diagnostic criteria. Large-scale epidemiological studies are required to provide an accurate estimate for prevalence and incidence of the condition. Meticulous diagnostic investigations which may require interdisciplinary teamwork are often warranted to reach an accurate diagnosis. A combination of interventional modalities, with a holistic approach, is key for successful management and improvement in patients' quality of life.

Management of Burning Mouth Syndrome

This article provides an update for the practicing dentist and/or oral and maxillofacial surgeon on the recognition, identification, and treatment of burning mouth syndrome (BMS). We discuss the most common clinical findings and most common causes of BMS. This article provides a classification flowchart that assists the practitioner in diagnosing and classifying BMS. The article then discusses the pathophysiology and treatment of BMS updated in the literature from the latest studies and reviews. Treatment can vary from topical or systemic medication to behavioral therapy.

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.

Long-term prognosis of burning mouth syndrome following treatment

The purpose of this study was to evaluate the long-term prognosis of patients with burning mouth syndrome (BMS) after the termination or discontinuation of treatment and to identify the clinical characteristics that might affect that prognosis. Of 769 patients with an oral burning sensation, 202 with primary BMS who had been treated for at least 3 months were included. Among them, 28 patients who responded to the treatment and 25 patients who did not were assigned to responder and non-responder groups, respectively. Based on telephone interviews, the responders were classified into relapse and non-relapse subgroups, and the non-responder group into persistence and remission subgroups. The majority of responders reported no oral discomfort since their last visit. Compared with the non-relapse subgroup, the relapse subgroup had significantly higher levels of xerostomia at the first visit (P = 0.026) and taste disturbance at the last visit (P = 0.015). The majority of non-responders reported persistent oral discomfort since their last visit. No significant differences were found in the characteristics of oral symptoms between the persistence and remission subgroups. In conclusion, the treatment outcomes in the majority of responders and non-responders were maintained following treatment. Xerostomia and taste disturbance were associated with relapse of oral discomfort in the responders.

Effectiveness of Nonpharmacologic Treatments of Burning Mouth Syndrome: A Systematic Review

AIMS

To assess the efficacy of nonpharmacologic treatments for burning mouth syndrome (BMS).

METHODS

PubMed, Scopus, Web of Science, and the Cochrane Central Register of Controlled Trials were systematically searched. Reference lists from the latest systematic reviews (2015 to 2020) on BMS treatment in the PubMed, Scopus, Web of Science, and Cochrane Library databases were also scrutinized. Randomized controlled trials (RCTs) or clinical controlled trials (CCTs) in English were considered eligible. Trials on photobiomodulation were excluded to avoid redundancy with recent publications. Risk of bias was established through the Cochrane Risk of Bias tool for RCTs and the Risk of Bias in Nonrandomized Studies of Interventions (ROBINS-I) tool for CCTs.

RESULTS

This review included 27 RCTs and 6 open clinical trials (OCTs) describing 14 different nonpharmacologic interventions. Eleven trials experimented with 600 to 800 mg/day of alpha-lipoic acid for 30 to 120 days, with 7 placebo-controlled studies showing significant pain relief. Four trials tested topical and systemic capsaicin for 7 to 30 days, with 2 placebo-controlled studies revealing significant efficacy. Four of the 5 trials testing acupuncture offered favorable evidence of pain relief. Two trials reported significant pain relief after a 2- to 3-month regimen with tongue protectors and showed no difference after aloe vera addition. Short-term pain relief was reported in anecdotal placebo-controlled trials deploying tocopherol, catuama, ultramicronized palmitoylethanolamide, group psychotherapy, cognitive therapy, and repetitive transcranial magnetic stimulation of the prefrontal cortex. Most therapies were safe.

CONCLUSION

Evidence was collected from highly biased, short-term, heterogenous studies mainly focused on BMS-related pain, with scarce data on quality of life, psychologic status, dysgeusia, and xerostomia. Long-term effectiveness of nonpharmacologic treatments should be further investigated, with a more rigorous, bias-proof study design.

Prevalence and Features of Laryngopharyngeal Reflux in Patients with Primary Burning Mouth Syndrome

OBJECTIVES/HYPOTHESIS

To investigate the prevalence and features of laryngopharyngeal reflux (LPR) in patients with primary burning mouth syndrome (BMS).

STUDY DESIGN

Prospective uncontrolled study.

METHODS

Patients who visited our Departments of Otolaryngology-Head and Neck and Maxillofacial surgery with BMS were prospectively recruited from September 2018 to September 2020. Patients benefited from dental, maxillofacial, otolaryngological examinations, and hypopharyngeal-esophageal impedance pH-monitoring (HEMII-pH). Oral, pharyngeal, and laryngeal findings and symptoms were rated with Reflux Sign Assessment (RSA) and Reflux Symptom Score-12 (RSS-12). Patients were treated with a combination of diet, pantoprazole, and alginate.

RESULTS

From the 81 included patients, 76 reported >1 pharyngeal reflux events (93.8%), accounting for 35 (46.1%), 24 (31.6%), and 17 (22.3%) acid, mixed, and nonacid LPR, respectively. Thirty-two patients had both LPR and gastroesophageal reflux disease (GERD). Thirty-eight patients benefited from pepsin saliva measurement, which was positive in 86.8% of cases. The mean scores of mouth/tongue burning, RSS-12, and RSA significantly improved from pre- to post-treatment (P < .004). At 3-month post-treatment, 62.5% of patients reported an improvement of mouth/tongue burning score. Patients with both GERD and LPR reported higher baseline RSS-12 and RSA scores.

CONCLUSION

Acid, weakly acid, and nonacid LPR may be involved in the development of BMS. The use of an appropriate treatment considering the reflux features is associated with an improvement of symptoms and findings.

Usefulness of Psychiatric Intervention in a Joint Consultation for the Treatment of Burning Mouth Syndrome: A Monocentric Retrospective Study

Primary burning mouth syndrome is a term used for chronic oral mucosal pain with no identifiable organic cause. The aim of the study was to evaluate the usefulness of a psychiatric intervention for treating burning mouth syndrome based on a joint consultation with a psychiatrist and a dermatologist. The study was proposed to all patients who visited this consultation group between 2001 and 2017 for the treatment of primary burning mouth syndrome. The patients answered a questionnaire that was administered via mail. Of the 57 patients diagnosed with primary burning mouth syndrome, 38 were included. Seven patients (18.4%) no longer had pain; 8 (21.1%) estimated that the pain had decreased by greater than 50%; 11 (28.9%) estimated the decrease at between 30 and 50%, and 12 (31.6%) estimated a less than 30% decrease. Only 14 patients (36.8%) remained under treatment with antidepressants, as compared to 63.2% before the psychiatric intervention. This psychiatric intervention could be considered a valuable tool in the global burning mouth syndrome treatment strategy.

Burning mouth syndrome: a review of etiology, diagnosis, and management

Burning mouth syndrome (BMS) is a chronic condition characterized by a burning sensation of the oral cavity and is often associated with taste disturbances and xerostomia. It primarily affects menopausal or postmenopausal women. Idiopathic or primary BMS can occur spontaneously and without any identifiable precipitating factors. When BMS is associated with systemic factors, it is defined as secondary BMS. While the exact etiology of BMS is still unknown, the condition appears to be multifactorial, and numerous local, systemic, and psychological factors have been associated with it. Primary BMS is a diagnosis of exclusion and can only be reached after all potential causes of secondary burning pain have been eliminated. Management strategies include reassurance of the patient as well as pharmacologic agents such as clonazepam, supplements such as α-lipoic acid, and psychological therapy.

Understanding of Burning Mouth Syndrome Based on Psychological Aspects

Burning mouth syndrome (BMS) is a chronic pain condition characterised by a persistent burning sensation in clinically normal oral mucosa. BMS most commonly occurs in middleaged and elderly women. Various local and systemic factors can cause oral burning symptoms. When all possible local and systemic factors are excluded, burning mouth symptoms can be diagnosed as BMS. Psychophysical tests and histopathological data suggest the involvement of peripheral and central neuropathic mechanisms in BMS etiopathogenesis. Psychological problems are frequently observed in BMS patients. Several mechanisms, including increased parafunctional habits, steroid dysregulation, central disinhibition due to taste dysfunction, and low dopamine levels in the brain, have been proposed as an explanation for the role of psychological factors in BMS pathophysiology. However, the causal relationship between BMS and psychological problems remains controversial. Given the neuropathic nature of BMS, treatment for it is similar to other neuropathic pain conditions. Although various treatment modalities, including pharmacological intervention, behavioural therapy and psychotherapy, have been proposed, there is no definitive treatment always effective for the majority of BMS patients. In conclusion, for better understanding of the relationship between BMS and psychological factors, well-designed prospective studies are needed. In addition, the evaluation and treatment of psychological problems are essential for successful management of BMS patients.

A diagnostic and therapeutic approach to primary burning mouth syndrome

Primary burning mouth syndrome (BMS) is an oral mucosal disorder that is characterized by a chronic and often debilitating intraoral burning sensation for which no localized or systemic cause can be found. BMS most commonly affects postmenopausal women. The pathophysiology of primary BMS is not well understood. Diagnosing BMS can prove to be challenging. BMS patients can also pose a therapeutic challenge to clinicians who are consulted to evaluate these patients. Most commonly used therapies include tricyclic antidepressants, α-lipoic acid, clonazepam, and cognitive-behavioral therapy. Clinical judgment, patient counseling, and monitoring of pain are important. Further research is required to assess the effectiveness of serotonin and newer serotonin-noradrenalin reuptake inhibitors.

Interventions for treating burning mouth syndrome

BACKGROUND

Burning mouth syndrome (BMS) is a term used for oral mucosal pain (burning pain or discomfort in the tongue, lips or entire oral cavity) without identifiable cause. General population prevalence varies from 0.1% to 3.9%. Many BMS patients indicate anxiety, depression, personality disorders and impaired quality of life (QoL). This review updates the previous versions published in 2000 and 2005.

OBJECTIVES

To determine the effectiveness and safety of any intervention versus placebo for symptom relief and changes in QoL, taste, and feeling of dryness in people with BMS.

SEARCH METHODS

Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 31 December 2015), the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 11) in the Cochrane Library (searched 31 December 2015), MEDLINE Ovid (1946 to 31 December 2015), and Embase Ovid (1980 to 31 December 2015). We searched ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform for ongoing trials. We placed no restrictions on the language or date of publication when searching the electronic databases SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing any treatment against placebo in people with BMS. The primary outcomes were symptom relief (pain/burning) and change in QoL. Secondary outcomes included change in taste, feeling of dryness, and adverse effects.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. Outcome data were analysed as short-term (up to three months) or long-term (three to six months).

MAIN RESULTS

We included 23 RCTs (1121 analysed participants; 83% female). Interventions were categorised as: antidepressants and antipsychotics, anticonvulsants, benzodiazepines, cholinergics, dietary supplements, electromagnetic radiation, physical barriers, psychological therapies, and topical treatments.Only one RCT was assessed at low risk of bias overall, four RCTs' risk of bias was unclear, and 18 studies were at high risk of bias. Overall quality of the evidence for effectiveness was very low for all interventions and all outcomes.Twenty-one RCTs assessed short-term symptom relief. There is very low-quality evidence of benefit from electromagnetic radiation (one RCT, 58 participants), topical benzodiazepines (two RCTs, 111 participants), physical barriers (one RCT, 50 participants), and anticonvulsants (one RCT, 100 participants). We found insufficient/contradictory evidence regarding the effectiveness of antidepressants, cholinergics, systemic benzodiazepines, dietary supplements or topical treatments. No RCT assessing psychological therapies evaluated short-term symptom relief.Four studies assessed long-term symptom relief. There is very low-quality evidence of a benefit from psychological therapies (one RCT, 30 participants), capsaicin oral rinse (topical treatment) (one RCT, 18 participants), and topical benzodiazepines (one RCT, 66 participants). We found no evidence of a difference for dietary supplements or lactoperoxidase oral rinse. No studies assessing antidepressants, anticonvulsants, cholinergics, electromagnetic radiation or physical barriers evaluated long-term symptom relief.Short-term change in QoL was assessed by seven studies (none long-term).The quality of evidence was very low. A benefit was found for electromagnetic radiation (one RCT, 58 participants), however findings were inconclusive for antidepressants, benzodiazepines, dietary supplements and physical barriers.Secondary outcomes (change in taste and feeling of dryness) were only assessed short-term, and the findings for both were also inconclusive.With regard to adverse effects, there is very low-quality evidence that antidepressants increase dizziness and drowsiness (one RCT, 37 participants), and that alpha lipoic acid increased headache (two RCTs, 118 participants) and gastrointestinal complaints (3 RCTs, 138 participants). We found insufficient/contradictory evidence regarding adverse events for anticonvulsants or benzodiazepines. Adverse events were poorly reported or unreported for cholinergics, electromagnetic radiation, and psychological therapies. No adverse events occurred from physical barriers or topical therapy use.

AUTHORS' CONCLUSIONS

Given BMS' potentially disabling nature, the need to identify effective modes of treatment for sufferers is vital. Due to the limited number of clinical trials at low risk of bias, there is insufficient evidence to support or refute the use of any interventions in managing BMS. Further clinical trials, with improved methodology and standardised outcome sets are required in order to establish which treatments are effective. Future studies are encouraged to assess the role of treatments used in other neuropathic pain conditions and psychological therapies in the treatment of BMS.

[BURNING MOUTH SYNDROME - A FLAME HARD TO EXTINGUISH]

Burning mouth syndrome (BMS) is a common condition that mostly affects elderly women. This symptom presents as a severe chronic burning sensation affecting the oral cavity and especially the dorsum of the tongue and its lateral aspects. Mouth burning sensation can result from an idiopathic primary condition or evolve from a secondary problem. The difficulty in reaching a correct diagnosis and especially to determining an appropriate treatment leads to considerable dissatisfaction among patients. In this paper we review the causes and the characteristics of the primary and secondary forms of the syndrome, the means of diagnosis and known treatment options.

The practical evaluation and management of patients with symptoms of a sore burning mouth

There are many etiologic factors to consider in a patient who presents with symptoms or sensations of a sore burning mouth. These range from local causes within the oral cavity to underlying systemic disease, including psychologic factors. This paper aims to describe the different clinical presentations and to outline a systematic approach to the evaluation and management of such patients. The clinician will be directed to the relevant diagnosis by following the traditional medical model of taking a focused history, performing a thorough clinical examination, considering the potential differential diagnoses, and requesting pertinent and appropriate investigations. The various differential diagnoses and broad treatment options will also be discussed and outlined. This paper will not, however, discuss burning mouth syndrome (oral dysesthesia), which is a diagnosis of exclusion, whereby the oral mucosa is clinically normal and there are no identifiable medical or dental causes to account for the patient's symptoms.

Burning Mouth Syndrome and "Burning Mouth Syndrome"

Burning mouth syndrome is distressing to both the patient and practitioner unable to determine the cause of the patient's symptoms. Burning mouth syndrome is a diagnosis of exclusion, which is used only after nutritional deficiencies, mucosal disease, fungal infections, hormonal disturbances and contact stomatitis have been ruled out. This article will explore the many causes and treatment of patients who present with a chief complaint of "my mouth burns," including symptomatic treatment for those with burning mouth syndrome.

[Burning mouth syndrome - a joint biopsychosocial approach]

Burning mouth syndrome (BMS) is a medical condition that is often refractory to conventional diagnostic and therapeutic methods. Patients suffering from BMS can benefit from a biopsychosocial approach in a joint, medical-psychological consultation model. Such a consultation exists at Geneva University Hospitals, involving the collaboration of the maxillo-facial and oral surgery division and the division of liaison psychiatry and crisis intervention, in order to take into account the multiple factors involved in BMS onset and persistence. This article will describe BMS clinical presentation, and present an integrate approach to treat these patients.

Burning Mouth Syndrome: A Review of the Etiopathologic Factors and Management

Burning mouth syndrome (BMS) is characterized by pain in the mouth with or with no inflammatory signs and no specific lesions. Synonyms found in literature include glossodynia, oral dysesthesia, glossopyrosis, glossalgia, stomatopyrosis, and stomatodynia. Burning mouth syndrome generally presents as a triad: Mouth pain, alteration in taste, and altered salivation, in the absence of visible mucosal lesions in the mouth. The syndrome generally manifests spontaneously, and the discomfort is typically of a continuous nature but increases in intensity during evening and at night. The etiopathogenesis seems to be complex and in a large number of patients probably involves interactions among local, systemic, and/or psychogenic factors. The differential diagnosis requires the exclusion of oral mucosal lesions or blood test alterations that can produce burning mouth sensation. Management is always based on the etiological agents involved. If burning persists after local or systemic conditions are treated, then treatment is aimed at controlling neuropathic symptoms. Treatment of BMS is still unsatisfactory, and there is no definitive cure. As a result, a multidisciplinary approach is required to bring the condition under better control. The aim of this review was to discuss several aspects of BMS, update current knowledge, and provide guidelines for patient management.

Burning mouth syndrome

INTRODUCTION

Burning mouth syndrome mainly affects women, particularly after the menopause, when its prevalence may be 18% to 33%.

METHODS AND OUTCOMES

We conducted a systematic overview, aiming to answer the following clinical question: What are the effects of selected treatments for burning mouth syndrome? We searched: Medline, Embase, The Cochrane Library, and other important databases up to January 2015 (Clinical Evidence overviews are updated periodically; please check our website for the most up-to-date version of this overview).

RESULTS

At this update, searching of electronic databases retrieved 70 studies. After deduplication and removal of conference abstracts, 45 records were screened for inclusion in the overview. Appraisal of titles and abstracts led to the exclusion of 25 studies and the further review of 20 full publications. Of the 20 full articles evaluated, one systematic review and nine RCTs were added at this update. We performed a GRADE evaluation for five PICO combinations.

CONCLUSIONS

In this systematic overview, we categorised the efficacy for six interventions based on information about the effectiveness and safety of alphalipoic acid, benzodiazepines, benzydamine hydrochloride, cognitive behavioural therapy (CBT), selective serotonin re-uptake inhibitors (SSRIs), and tricyclic antidepressants.

An overview of burning mouth syndrome

Burning mouth syndrome (BMS) is characterised by the presence of a burning sensation in the oral mucosa in the absence of any clinically apparent mucosal sign. It occurs more commonly in older women and often affects the tongue tip and lateral borders, lips, and hard and soft palates. Besides the burning sensation, patients with BMS may complain of unremitting oral mucosal pain, dysgeusia, and xerostomia. The exact pathophysiology of primary BMS remains unknown. A major challenge for the clinician is the treatment of BMS: identifying possible causative factors is the first step, but BMS is often idiopathic. Drug therapy, in addition to behavioural therapy and psychotherapy, may help to eliminate the symptoms. Considering the growing incidence of BMS in older people, further research is required to determine the true efficacy of current management strategies for patients with this disorder.

Efficacy of low-level laser therapy for the treatment of burning mouth syndrome: a randomized, controlled trial

The aim of the present study was to assess the effect of low-level laser therapy (LLLT) in the treatment of burning mouth syndrome (BMS). A diode laser was used in 78 BMS patients who were randomly assigned into four groups: IR1W, n = 20 (830 nm, 100 mW, 5 J, 176 J/cm2, 50 s, LLLT weekly sessions, 10 sessions); IR3W, n = 20 (830 nm, 100 mW, 5 J, 176 J/cm2, 50 s, three LLLT weekly sessions, 9 sessions); red laser, n = 19 (685 nm, 35 mW, 2 J, 72 J/cm2, 58 s, three LLLT weekly sessions, 9 sessions); and control-group (CG), n = 19. Symptoms were assessed at the end of the treatment and eight weeks later; quality of life related to oral health was assessed using the Oral Health Impact Profile (OHIP-14). Statistical analysis was carried out using repeated measures analysis of variance followed by the posthoc Tukey test. There was significant reduction of the symptoms in all groups at the end of the treatment, which was maintained in the follow-up. The scores of the IR1W and IR3W laser groups differed significantly from those of the CG. There was also a decrease in the OHIP-14 scores in the four groups. The IR3W laser group scores differed significantly from those of the CG. LLLT reduces the symptoms of BMS and may be an alternative therapeutic strategy for the relief of symptoms in patients with BMS.

Burning mouth syndrome: a review and update

Burning mouth syndrome (BMS) is mainly found in middle aged or elderly women and is characterized by intense burning or itching sensation of the tongue or other regions of the oral mucosa. It can be accompanied by xerostomia and dysgeusia. The syndrome generally manifests spontaneously, and the discomfort is typically of a continuous nature but increases in intensity during the evening and at night. Although BMS classically has been attributed to a range of factors, in recent years evidence has been obtained relating it peripheral (sensory C and/or trigeminal nerve fibers) or central neuropathic disturbances (involving the nigrostriatal dopaminergic system). The differential diagnosis requires the exclusion of oral mucosal lesions or blood test alterations that can produce burning mouth sensation. Patient management is based on the avoidance of causes of oral irritation and the provision of psychological support. Drug treatment for burning sensation in primary BMS of peripheral origin can consist of topical clonazepam, while central type BMS appears to improve with the use of antidepressants such as duloxetine, antiseizure drugs such as gabapentin, or amisulpride.

Orofacial pain syndromes: evaluation and management

Patients will often visit their primary medical practitioner with orofacial pain complaints. Hence, it is important to recognize and have an understanding of these conditions to properly evaluate and potentially manage these disorders. If the practitioner is uncertain or uncomfortable with these conditions, then patient referral to a knowledgeable health care practitioner should be considered for further evaluation and management. In this article, the evaluation and management of various neuropathic, neurovascular, and vascular pains are discussed.

[Burning mouth syndrome: pathogenic and therapeutic concepts]

Burning mouth syndrome (BMS) is a chronic pain condition characterized by pain, burning sensations and dryness within an oral mucosa, without any clinical changes of the latter. It occurs approximately seven times more frequently in women, mostly in perimenopausal age. The psychiatric aspect of BMS is significant: the most frequent co-morbidities are depression and anxiety disorders, and a number of psychotropic drugs play an essential role in its treatment. In the present review, the most important pathogenic and treatment concepts of BMS have been discussed. The BMS may be similar to neuropathic pain and has some related pathogenic elements with fibromyalgia and the restless leg syndrome. In primary BMS, the features of presynaptic dysfunction of dopaminergic neurons and deficiency of endogenous dopamine levels have been demonstrated. Other neurotransmitters such as serotonin, noradrenaline, histamine as well as hormonal and inflammatory factors may also play a role in the pathogenesis of BMS. In the pharmacological treatment of BMS a variety of drugs have been used including benzodiazepines, anticonvulsants, antidepressants and atypical antipsychotic drugs. In the final part of the paper, the possibility of using atypical antipsychotic drug, olanzapine, in the treatment of BMS has been discussed. In the context of the recent studies on this topic, a case of female patient with the BMS lasting more than ten years has been mentioned, in whom the treatment with olanzapine brought about a rapid and significant reduction of symptoms. The probable mechanism of the therapeutic effect of olanzapine in BMS can include its effect on dopaminergic receptors and probably also on histaminergic, noradrenergic and serotonergic ones.

Management of burning mouth syndrome taking into consideration various etiologic factors

The aim of the research was to detect the stomatologic, endocrine and psycho-neurologic status in patients with burning mouth syndrome, elaborate different diagnostic criteria and effective therapy for the patients with burning mouth syndrome. 92 patients with burning mouth syndrome were studied. Patients ranged in age from 28 to 72 years. The conducted studies gave the possibility to make conclusions, the most important of which are: burning mouth syndrome (BMS) is not only stomatologic problem; this psychosomatic syndrome belongs to gerontologic disease and tendency of its "rejuvenation" was revealed as well (in the current study --2 women (28 and 32 year old, and 38 year old man); degree of revelation of the symptoms of depression, anxiety, obsession and somatization is closely related with duration of the diseases. These symptoms are progressing together with aging and reach the peak at 60-70 years old. Individual scheme of therapy was developed on the background of clinico-paraclinical study.

[Burning sensation in oral cavity--burning mouth syndrome in everyday medical practice]

Burning mouth syndrome (BMS) refers to chronic orofacial pain, unaccompanied by mucosal lesions or other evident clinical signs. It is observed principally in middle-aged patients and postmenopausal women. BMS is characterized by an intense burning or stinging sensation, typically on the tongue or in other areas of the oral mucosa. It can be accompanied by other sensory disorders such as dry mouth or taste alterations. Probably of multifactorial origin, and often idiopathic, with a still unknown etiopathogenesis in which local, systemic and psychological factors are implicated. Currently there is no consensus on the diagnosis and classification of BMS. This study reviews the literature on this syndrome, with special reference to the etiological factors that may be involved and the clinical aspects they present. The diagnostic criteria that should be followed and the therapeutic management are discussed with reference to the most recent studies.

A systematic review of acupuncture or acupoint injection for management of burning mouth syndrome

OBJECTIVE

Burning mouth syndrome (BMS) is a common chronic pain condition that lacks a satisfactory treatment approach. This systematic review was designed to examine the effects of acupuncture or acupoint injection on the management of BMS and to evaluate the evidence supporting the use of acupuncture therapy for BMS in clinical practice.

METHOD AND MATERIALS

The following databases were searched for relevant articles: Cochrane Oral Health Group Trials Register (July 2011), Cochrane Central Register of Controlled Trials (issue 7, 2011), MEDLINE (1966 to June 2011), and electronic medical database from the China-National Knowledge Infrastructure (1979 to June 2011). Articles were screened, and the quality of the included trials was assessed independently by two reviewers.

RESULTS

After screening, nine studies with 547 randomized patients were included in this review. All nine articles were published in Chinese and were clinical trial studies with a Jadad score < 3. Their results showed that acupuncture/acupoint injection may benefit patients with BMS. The evidence supported the efficacy of acupuncture/acupoint injection therapy in reducing BMS pain and related symptoms.

CONCLUSION

In light of the positive outcomes reported, the use of acupuncture therapy for BMS patients warrants further research.

Burning mouth syndrome: a discussion of a complex pathology

Burning mouth syndrome is a complex pathology for which there is very little information about the etiology and pathogenesis. This lack of knowledge leaves patients with suboptimal treatments. This article discusses the existing scientific evidence about this disease. Since topical oral use of clonazepam have been shown to be effective and safe to treat some patients suffering with burning mouth syndrome, formulations including clonazepam are included with this article. Compounding topical preparations of clonazepam offers opportunities for compounding pharmacists to be more involved in improving the quality of life of burning mouth syndrome patients.

[Treatment of oral paresthesia in a joint stomato-psychological consultation model]

Medically unexplained oral paresthesia, or burning mouth syndrome, is a condition that primarily affects female patients, and often leads them to consult their dentist, who may feel helpless concerning the repeated complaints of these patients. Therefore, they tend to increase visits to various health professionals in an attempt to find a relief. Since 1996, a joint stomato-psychological consultation has been established in Geneva University Hospitals, in order to offer adequate care to these patients. This article describes this type of treatment, and the referral issues.

Pain and pain behavior in burning mouth syndrome: a pain diary study

AIMS

To characterize pain related to primary burning mouth syndrome (BMS) in terms of intensity, interference, and distress caused by the pain, as well as factors influencing the pain across a period of 2 weeks, and to study the use of coping and management strategies on a daily basis.

METHODS

Fifty-two female patients with primary BMS completed a 2-week pain diary. Pain intensity, interference, distress, and mood on a 0 to 10 numeric rating scale (NRS), as well as pain amplifying and alleviating factors, were recorded three times a day. The use of treatments (medication or other means) and coping strategies were recorded at the end of each day. Coefficient of variation, repeated measures analysis of variance, and correlative methods were used to assess the between- and within-subject variation, pain patterns, and associations between various pain scores.

RESULTS

The overall mean pain intensity score of the 14 diary days was 3.1 (SD: 1.7); there was considerable variation in pain intensity between patients. Most patients experienced intermittent pain. On average, pain intensity increased from the morning to the evening. Intercorrelations between pain intensity, interference, distress, and mood were high, varying between rs = .75 and rs = .93 (P < .001). Pungent or hot food or beverages, stress, and tiredness were the most frequently mentioned pain-amplifying factors. The corresponding pain-alleviating factors were eating, sucking pastilles, drinking cold beverages, and relaxation. Thirty (58%) patients used pain medication and 35% reported using other means to alleviate their BMS pain. There was large variation in the use of coping strategies -between subjects.

CONCLUSION

There were considerable differences in pain, in factors influencing the pain, and in pain behavior across BMS patients. This indicates that patient information and education as well as treatment of BMS pain should be individualized.

Burning mouth syndrome: a challenge for dental practitioners and patients

A retrospective study was conducted on patients with burning mouth syndrome (BMS) to assess demographics, onset characteristics, temporal behavior (frequency), duration, and progression of oral burning symptoms. Additionally, treatments provided by health practitioners prior to a definitive diagnosis of BMS were analyzed with an overview of current management strategies. The records of 49 adult patients diagnosed with BMS were reviewed. Descriptive statistics and a Pearson correlation with a statistical significance at p < 0.05 were utilized to analyze the data. The majority of patients were mid-life white women who reported a sudden onset of constant oral burning symptoms that increased in intensity. On average, patients reported oral burning symptoms for 41 months (standard deviation = 73.5, range = 2-360 months, median = 20 months), and 38 of the patients received/trialed 71 various interventions (mean = 1.9) prior to receiving a definitive diagnosis for their oral burning symptoms. This study sample shared many characteristics with those reported previously in the literature. The authors found that patients frequently reported delays in receiving a definitive diagnosis with an array of various trialed interventions. For this reason, the authors provide this overview of current management strategies in order to assist dental practitioners in providing appropriate interventions for patients with BMS.

Management of burning mouth syndrome

Burning mouth syndrome is a challenging condition in terms of both diagnosis and management. These challenges lead to frustration for patients and difficulties for dental practitioners. Unfortunately, delays are common between initial presentation and definitive diagnosis, and also between diagnosis and appropriate management. Furthermore, interventions are often undertaken without a working diagnosis, knowledge of the underlying condition or knowledge of best management strategies for this form of chronic orofacial pain. This article discusses potential reasons for diagnostic delays. It also presents current strategies for managing burning mouth syndrome, to assist the dental practitioner in making prudent therapeutic choices.

Group psychotherapy: an additional approach to burning mouth syndrome

INTRODUCTION

Glossodynia or burning mouth syndrome (BMS) is a common and poorly understood disorder. Its treatment is uncertain. Otherwise, there is some evidence of the importance of psychological factors in the genesis of this disease.

OBJECTIVES

Verify the usefulness of group psychotherapy as an adjuvant therapeutic method in the treatment of BMS. CASUISTICS AND METHODS: The study group consisted of 64 consecutive patients with a clinical diagnosis of BMS seen at the Stomatology Outpatient Clinic, ENT Department, Sao Paulo University Medical School, between May 2002 and May 2007. All the patients were submitted to physical examination, laboratorial screening tests, psychological assessment (Crown-Crisp Experimental Inventory), and answered a short form of the McGill Pain Questionnaire. Only 44 patients who did not show any abnormality in the protocol exams entered the study. Twenty-four of them underwent group psychotherapy. Twenty patients received placebo. Chi-square test was applied to compare the results of treatment with or without psychotherapy.

RESULTS

There were 15 men and 29 women in the study group. Tongue burning was the main complaint of the patients. Improvement of symptoms was reported by 17 (70.8%) of the patients undergoing psychotherapy, while among those who did not eight (40%) had improvement of symptoms (P=.04).

CONCLUSION

Psychological assessment demonstrated a close correlation between symptoms and psychological factors, suggesting that group psychotherapy is an important alternative to conventional treatment methods.

Salivation quantum--stomatopyrosis--autogenic training

Stomatopyrosis of 'burning mouth' syndrome, in a narrower sense of definition, is a condition characterized by sensation of burning and heating in mouth, despite its normal mucosa. This research has been directed towards treatment of stomatopyrosis, putting emphasis on the implementation of psychopharmacotherapy and psychotherapy. The research was conducted on altogether 120 respondents suffering from stomatopyrosis. The respondents were divided into two equal groups: each one comprising 60 members. All the respondents were treated by means of a standard topical therapy. All the patients were assessed clinically and by means of psychological tests measuring depression and anxiety four times: once before the treatment, after one month, after two months and after four months since the beginning of the treatment. The acquired data were afterwards statistically processed. When grading the symptoms on VAS, i.e. visual analogous scale, the subjective assessment of symptoms was marked as 7-8 cm, which shows a high degree of burning sensation. According to our study, the quantity of saliva, which was at the beginning of the research slightly decreased, normalized after the treatment. Apart from the clinical investigation of stomatopyrosis, we applied Depression and Anxiety questionnaires. On the basis of our research, we have concluded the following: the comorbidity of stomatopyrosis with the phenomena of anxiety and depression proves that, among other factors, there is a psychogenic aetiology of this disease. Autogenic training, which is a psychotherapeutic anxiolytic technique, is a therapy of choice for stomatopyrosis, which contributes not only to the elimination of oral complaints, but to the emotional rehabilitation of the patients as well, and to the reduction of dryness in the mouth.

Regression analysis of the symptoms

Stomatopyrosis of 'burning mouth' syndrome, in a narrower sense of definition, is a condition characterized by sensation of burning and heating in mouth, despite its normal mucosa. This research has been directed towards treatment of stomatopyrosis, putting emphasis on the implementation of psychopharmacotherapy and psychotherapy. The research was conducted on altogether 120 respondents suffering from stomatopyrosis. The respondents were divided into two equal groups: each one comprising 60 members. All the respondents were treated by means of a standard topical therapy. All the patients were assessed clinically and by means of psychological tests measuring depression and anxiety four times: once before the treatment, after one month, after two months and after four months since the beginning of the treatment. The acquired data were afterwards statistically processed. Our research led to the conclusion that stomatopyrosis occurs with elderly people, primarily women. Regarding their occupation, majority of the respondents were clerks, followed by retirees. The burning sensation in mouth was present with all the respondents, the dominating site being the lips, while the nature of sensation was reported as mostly unbearable. Anxiety, tension and stress tend to aggravate the symptoms. When grading the symptoms on VAS, i.e. visual analogous scale, the subjective assessment of symptoms was marked as 7-8 cm, which shows a high degree of burning sensation. According to our study, the quantity of saliva, which was at the beginning of the research slightly decreased, normalized after the treatment. Apart from the clinical investigation of stomatopyrosis, we applied Depression and Anxiety questionnaires. During the therapy, the results of the depression test have shown a decrease in depression (from 56.7% to 0.00%), which is particularly apparent in the group treated by autogenic training and in the first group of respondents, i.e. the one treated with antidepressants. The Anxiety tests have shown a higher percentage and intensity of anxiety with men (62.5%, as opposed to women - 32.5%) in the beginning, which has dropped to 7.5% with men during the treatment and 8.8% with women. Clinical presentation of stomatopyrosis has also apparently improved. This improvement in clinical symptoms and psychological condition of patients is statistically significant. On the basis of our research, we have concluded the following: the comorbidity of stomatopyrosis with the phenomena of anxiety and depression proves that, among other factors, there is a psychogenic aetiology of this disease. Further research should provide answers to the questions whether stomatopyrosis is a psychosomatic or a conversive disorder Antidepressants and anxiolytics have an important role in the therapy of stomatopyrosis. Autogenic training, which is a psychotherapeutic anxiolytic technique, is a therapy of choice for stomatopyrosis, which contributes not only to the elimination of oral complaints, but to the emotional rehabilitation of the patients as well.

[Burning mouth syndrome]

Burning mouth syndrome is characterized by a painful burning or stinging sensation affecting the tongue or other areas of the mouth without obvious signs of an organic cause on physical examination. A burning mouth sensation can occur in several cutaneous or systemic diseases that must be ruled out prior to making a diagnosis of burning mouth syndrome, since this term is used exclusively to refer to idiopathic forms and is included within the cutaneous sensory disorders. In most cases, patients with burning mouth syndrome have accompanying psychologic or psychiatric conditions. Consequently, the syndrome has traditionally been included among the psychogenic dermatoses. However, it is currently unclear whether psychologic factors are a cause or a consequence of the syndrome, or whether each exacerbates the other. Recent studies propose the etiology to be neurologic, either neuropathic or related to taste.

Burning mouth syndrome

Burning mouth syndrome (BMS) is characterized by oral burning or similar pain in the absence of detectable oral mucosa changes. This condition is more common among middle-aged and elderly women. Although various local, systemic, and psychological factors are considered to be possible causes of BMS, it is still a challenge in the field of oral medicine. The aim of this review was to discuss several aspects of BMS, update current knowledge, and provide guidelines for patient management.

Treatment of smarting symptoms in the oral mucosa by appliance of lingual acrylic splints

The aim of the present study was to evaluate the relieving effect on smarting symptoms in the oral mucosa by the use of lingual acrylic splints. Recruited for the study were 53 persons, 48 women and 5 men, with smarting symptoms in the oral mucosa, not associated with general disease, and with signs of erythema, most often on the apex of the tongue, and/or crenated tongue. Symptoms were registered from the tongue in 49 cases, the palate in 28 cases and the lips in 15 cases. A lingual acrylic splint was applied in the lower jaw behind the front teeth, not covering the occlusal surfaces and it was kept in the mouth day and night. At an average the splint was used in 8 months. A group of 10 women was recruited for comparison. These women were just instructed to avoid tongue pressing for at least a two month period. All patients were asked whether the treatment affected the symptoms and they registered their opinion on a 100 mm VAS line with end effect points "not helped at all/deteriorated" and "now completely without symptoms". On the question whether the treatment had affected the symptoms, the average result was 55 mm and median value 64 mm. The treatment results were somewhat better among those with moderate initial symptoms compared to those with severe symptoms. Interestingly, in the group for comparison, symptom VAS values improved significantly from 60 to 41 mm (P < 0.05).

CONCLUSION

Treatment of smarting symptoms in the oral mucosa may to a great extent be relieved by the application of an acrylic lingual splint. However, before using this splint method, an effort should be made to make the patient actively avoid tongue pressure.

The burning mouth

Burning in the mouth in and of itself is not all that uncommon. It may result from a variety of local or generalized oral mucosal disorders, or may be secondary to referred phenomena from other locations. Primary burning mouth syndrome, on the other hand, is relatively uncommon. Burning mouth syndrome is an idiopathic pain disorder, which appears to be neuropathic in origin. Thoughts on management of secondary and particularly primary burning mouth syndrome are discussed.

An up-to-date view on burning mouth syndrome

Burning mouth syndrome (BMS) is a chronic intraoral pain condition unaccompanied by clinical lesions or systemic diseases. Its aetiology is unknown. Several recent studies suggest that BMS may be a neuropathic condition, though it is still uncertain whether it is a peripheral and/or a central neurogenic dysfunction. Research indicates that BMS includes psychological components such as anxiety, depression, cancerophobia. Professional delay in diagnosing, referring and managing BMS patients occurs commonly. The treatment of BMS is possible but not yet satisfactory. This review, examines recent data on the aetiology, pathogenesis and clinical management of the syndrome.
