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.

A Case Report of Burning Mouth Syndrome with Dry Mouth Managed by Kampo Medicine.

The patient was a 56-year-old woman who complained of chronic pain involving her tongue. We diagnosed her with burning mouth syndrome (BMS) based on exclusion of any local factors or systemic conditions. The patient not only had tongue pain but also had other signs and symptoms like scalloped tongue, dry mouth, and headache. To manage these additional issues, we used Goreisan, an herbal Kampo medicine, as a complementary alternative medicine (CAM) approach along with cognitive behavioral therapy (CBT). The patient's BMS was successfully managed with the combination of CAM and CBT, which may suggest that the pathophysiology for BMS might be nociplastic pain rather than purely nociceptive or neuropathic.

Innovative histological and histochemical characterization of tongue biopsies from patients with burning mouth syndrome.

OBJECTIVES: The present pilot study aims to perform an innovative histological and histochemical characterization of samples from patients with burning mouth syndrome (BMS) to correlate these findings with the clinical scenario. METHODS: To carry out this objective, the study samples were stained with the hematoxylin-eosin stain and later, an histochemical study was carried out to determine the composition of the extracellular matrix (ECM) using the stains of Alcian Blue, Picrosirius, Reticulin from Gomori and Verhoeff. RESULTS: The results of this study revealed histological patterns compatible with cellular hypertrophy in different layers of the epithelium as well as a greater keratinization in BMS cases. On the other hand, a lower amount of proteoglycans and a greater amount of collagen fibers were observed compared to the control. In addition, older patients had fewer reticular fibers and younger patients had fewer elastic fibers compared to the control. CONCLUSIONS: In conclusion, the present study shows the existence of a correlation between the histological patterns, age and symptoms of patients with BMS. Therefore, it is necessary to develop synergistic studies in order to assess and implement new classification systems that could improve the therapeutic approach of patients with BMS.

[My tongue is burning!-Glossodynia/orofacial pain disorder]. / Meine Zunge brennt! ­ Glossodynie/orofaziales Schmerzsyndrom.

Glossodynia or orofacial pain disorder is known as burning mouth syndrome. It is a therapeutic challenge. Its etiology is not well defined. Recent studies show not only a correlation with neuropathic changes, but there are also indications of comorbidities such as depression, anxiety, and carcinophobia. These can also manifest as a reaction to the disease and are not necessarily considered causative. Burning mouth syndrome poses a diagnostic challenge since its differential diagnosis is broad. With regard to dermatological aspects, lichen planus mucosae, oral leucoplakia, pemphigus vulgaris, and aphthous mouth ulcers should be considered. Diabetes, anemia, vitamin deficiency, and endocrinological influences should be considered regarding the predominance of elderly and female patients. Meta-analyses of treatment studies usually show a low level of evidence of the randomized, controlled trials. According to the literature mainly psychotherapy and antidepressants are proposed for therapy. Alpha lipoic acid as a dietary supplement shows short-term improvement and low-level laser therapy might have some benefit.

Síndrome da ardência bucal: relato de caso clínico / Oral burning syndrome: a clinical case report

O presente estudo teve como objetivo principal descrever por meio de um relato de caso clínico o diagnóstico e a conduta clínica de uma paciente portadora da Síndrome da Ardência Bucal (SAB). A SAB é definida como uma dor crônica e de difícil diagnóstico e difícil tratamento. O local mais acometido pela SAB é a língua, lábios e mucosa jugal, mas pode estar presente em qualquer parte da mucosa oral, causando desconforto e interferindo na qualidade de vida do paciente. Paciente do sexo feminino, leucoderma, 39 anos, sem histórico de doenças sistêmicas, saúde geral em bom estado, procurou atendimento no Centro Universitário da Serra Gaúcha ­ FSG por apresentar sensação de ardência recorrente na língua e na mucosa, que aumentava em momentos de estresse ou durante a ingestão de alimentos cítricos, picantes ou quentes. A paciente realizou exames complementares (hemograma completo, glicemia de jejum, exame de vitamina B12) e primeiramente, iniciou-se o tratamento com antifúngico tópico para remoção de uma camada esbranquiçada presente no dorso da língua. Após a remissão desta, foi utilizado AD-Muc tópico 2 vezes ao dia, durante 2 semanas e relatou ter reduzido seus sintomas em torno de 70%. A paciente ainda apresentava xerostomia e, então foi prescrita saliva artificial. A paciente teve a regressão total de seus sintomas. Pode-se concluir que diversos fatores etiológicos estão relacionados com a SAB, porém sua causa específica permanece desconhecida. O tratamento é paliativo, entretanto, o Ad-muc tópico se mostrou eficaz na redução da sintomatologia da SAB juntamente com o uso da saliva artificial(AU)

The present study aimed to describe, through a clinical case report, the diagnosis and clinical conduct of a patient with Burning Mouth Syndrome (BMS). BMSis defined as chronic pain that is difficult to diagnose and difficult to treat. The site most affected by BMS is the tongue, lips, and cheek mucosa, but it can be present in any part of the oral mucosa, causing discomfort and interfering with the patient's quality of life. Female patient, leucoderma, 39 years old, with no history of systemic diseases, general health in good condition, sought care at the Centro Universitário da Serra Gaúcha - FSG for presenting a recurrent burning sensation in the tongue and mucosa, which increased in times of stress or while eating citrus, spicy or hot foods. The patient underwent complementary tests (complete blood count, fasting blood glucose, vitamin B12 test) and first, treatment with topical antifungal was started to remove a whitish layer present on the back of the tongue. After remission, topical AD-Muc was used twice a day for 2 weeks and reported to have reduced his symptoms by around 70%. The patient still had xerostomia and then artificial saliva was prescribed. The patient had a total regression of her symptoms. It can be concluded that several etiological factors are related to SAB, but its specific cause remains unknown. Treatment is palliative, however, topical Ad-muc is effective in reducing the symptomsof BMS also with the use of artificial saliva(AU)

Burning mouth syndrome: a review of therapeutic approach.

Burning mouth syndrome (BMS) is described by an intense burning sensation of the tongue or other oral areas without a clear etiopathology. The diagnosis of BMS is challenging due to variations of manifestations. The management of BMS is complicated due to the complex etiology of the disease. Many medications and treatment methods have been recommended for BMS management, but no one confirmed as the standard method. In this study, the therapeutic approaches of BMS were evaluated. The data of the article was obtained from PubMed/MEDLINE, Cochrane Library, and Web of Science. The following terms including "burning mouth syndrome", "therapy", and "treatment" were used for search in the databases. A wide range of articles about the therapeutic approach of BMS was searched and reviewed. Pharmacological and non-pharmacological approaches have been used for BMS management. Pharmacological treatments are including Capsaicin, Clonazepam, Low-dose aripiprazole, Alpha-lipoic acid, Duloxetine, Amitriptyline, Gabapentin, and Pregabalin, and ultra-micronized palmitoylethanolamide. Non-pharmacological therapies for BMS are cognitive therapy, Electroconvulsive therapy, Laser therapy, Acupuncture and auriculotherapy, Transcranial Magnetic Stimulation (rTMS), Salivary Mechanical Stimulation, and Botulinum Toxin. A detailed assessment of the etiology and pathophysiology of BMS, and having information about novel therapeutic interventions are essential for the management of BMS.

Síndrome de boca ardiente y factores asociados: estudio retrospectivo de casos y controles / Burning mouth syndrome and associated factors: A case-control retrospective study

Antecedentes y objetivo: El síndrome de boca ardiente (SBA) puede definirse como ardor o disestesia en la lengua y/u otras áreas de la mucosa bucal, en ausencia de lesiones que puedan justificarlo. Su incidencia es mayor en pacientes de sexo femenino, de edades comprendidas entre 50 y 60 años. Estas molestias suelen recurrir diariamente, provocando un deterioro de la calidad de vida. El objetivo del estudio fue evaluar la asociación entre diversos factores patogénicos y el SBA. Pacientes y métodos: Se estudiaron de forma retrospectiva 736 historias clínicas de pacientes diagnosticados de SBA y 132 historias clínicas de pacientes control. El período de estudio se extendió desde enero de 1990 a diciembre de 2014. El protocolo incluyó: sexo, edad, tipo de molestia bucal y localización, entre otras variables. Resultados: El análisis de la asociación entre los factores patogénicos y el diagnóstico de SBA mostró significación estadística en solo 3 de ellos: factores desencadenantes (p = 0,003), hábitos parafuncionales (p = 0,006) e higiene oral (p = 0,012). No se encontraron diferencias significativas en la incidencia del SBA por sexos (p = 0,408), ni asociación entre el SBA y los factores de abuso de sustancias (p = 0,915), patología sistémica (p = 0,685) y hábitos alimentarios (p = 0,904). Conclusiones: Los hábitos parafuncionales como el bruxismo y los movimientos anormales de la lengua y labios pueden explicar la sintomatología del SBA. Hay que tener siempre en cuenta los aspectos psicológicos y los factores sistémicos. Como alteración de carácter multifactorial que es, el tratamiento del SBA debe enfocarse de manera holística (AU)

Background and objective: Burning mouth syndrome (BMS) can be defined as burning pain or dysesthesia on the tongue and/or other sites of the oral mucosa without a causative identifiable lesion. The discomfort is usually of daily recurrence, with a higher incidence among people aged 50 to 60 years, affecting mostly the female sex and diminishing their quality of life. The aim of this study was to evaluate the association between several pathogenic factors and burning mouth syndrome. Patients and methods: 736 medical records of patients diagnosed of burning mouth syndrome and 132 medical records for the control group were studied retrospectively. The study time span was from January 1990 to December 2014. The protocol included: sex, age, type of oral discomfort and location, among other factors. Results: Analysis of the association between pathogenic factors and BMS diagnosis revealed that only 3 factors showed a statistically significant association: triggers (P = .003), parafunctional habits (P = .006), and oral hygiene (P = .012). There were neither statistically significant differences in BMS incidence between sex groups (P= .408) nor association of BMS with the pathogenic factors of substance abuse (P = .915), systemic pathology (P = .685), and dietary habits (P = .904). Conclusions: Parafunctional habits like bruxism and abnormal movements of tongue and lips can explain the BMS main symptomatology. Psychological aspects and systemic factors should be always considered. As a multifactorial disorder, the treatment of BMS should be executed in a holistic way (AU)

Burning mouth syndrome: a review of recent literature.

Burning mouth syndrome (BMS) is a complex chronic disorder of orofacial sensation that is challenging in both diagnosis and treatment. The diagnosis of BMS is primarily one of exclusion, and recently classification of the disorder has been challenged. Although the exact pathophysiology of primary BMS is unknown, there has been a growing body of work to provide insight into the pathogenesis of the disorder over the past few years. Pharmacological treatments recently reported to have some success in BMS include anxiolytics, anticonvulsants, antidepressants, atypical antipsychotics, histamine receptor antagonist, and dopamine agonists. In addition, other therapies and treatments are being considered. This paper reports many of the most recent data related to BMS and its classification, diagnosis, impact on quality of life, pathophysiology, co-morbidities, and pharmacological and non-pharmacological treatments.

[Burning mouth syndrome: pathogenic and therapeutic concepts]. / Zespól pieczenia w jamie ustnej (burning mouth syndrome)--koncepcje patogenetyczne i terapeutyczne.

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.

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.

Ação do tratamento homeopático na sintomatologia da síndrome da ardência bucal em duas fases: estudo duplo cego placebo controlado e estudo aberto / Action of homeopathic treatment in the symptoms of burning mouth syndrome in two phases: double-blind placebo controlled study and open trial study

A síndrome da ardência bucal (SAB) é definida como uma sensação de queimação principalmente na língua, palato e ou gengiva ou em outra região da mucosa oral, na ausência de lesão oral específica. Caracterizada por uma contínua, espontânea, e intensa sensação de queimação como se a boca ou a língua tivessem sido escaldadas. A etiologia é pobremente compreendida embora nova evidências como neurológicas, emocionais e alterações hormonais estejam relacionadas com a SAB. É mais comum entre as mulheres na pós-menopausa e causa intenso desconforto e sofrimento. Antidepressivos tricíclicos, benzodiazepínicos e drogas antipsicóticas são as opções mais indicadas no tratamento e mostraram resultados variáveis. O objetivo desse estudo foi investigar a ação do tratamento homeopático na sintomatologia da ardência bucal em duas fases: estudo duplo-cego placebo-controlado e estudo aberto. Associados à SAB, níveis de ansiedade e depressão também foram considerados. Esse estudo foi composto por 31 pacientes diagnosticados com SAB na Clinica do Departamento de Estomatologia da FOUSP, entre julho de 2011 a setembro de 2012. Estes (25 mulheres, e 6 homens média de idade de 58,93 anos, variação 34-85 anos), foram randomizados em dois grupos G1(Arsenicum album) e G2 (Placebo), durante 90 dias, com washout de 30 dias (FASE1). O sintoma ardor bucal e a resposta terapêutica foram avaliadas utilizando uma escala visual de sintomatologia (EVS) a cada visita. Para se avaliar o Efeito global percebido (EGP), utilizou-se uma escala de 5 pontos ao término da FASE 1. O nível de redução sobre o sintoma ardor avaliado pela EVS e o efeito Global percebido (EGP) foram estatisticamente significantes para o grupo G1(Arsenicum album) com redução de sintoma de 44,50% em relação ao placebo (12,65%). Na FASE 2 (estud0 aberto), 28 pacientes que participaram da FASE 1, receberam medicamento homeopático individualizado durante 7 meses, com visitas mensais e Washout de 60 dias. O sintoma ardor e resposta terapêutica foram avaliados utilizando (EVS) inicial obtido ao final da FASE 1, e no final da FASE 2. Houve redução de sintomas no final do tratamento de 64,60%. A análise dos dados nos permitiu concluir que ambos os tratamentos FASE 1 e FASE 2 tiveram efeito terapêutico com significância estatística. Houve efetividade do tratamento homeopático sobre o placebo na sintomatologia da ardência bucal. A FASE 2 apresentou melhores resultados quando comparados aos resultados obtidos na FASE 1. O Grupo Medicamento da FASE 2 foi mais eficaz quando comparado aos Grupos, Medicamento e Placebo da FASE 1, com significância estatística no intervalo de confiança estabelecido. Os melhores resultados foram observados nos pacientes com sintomas entre 6 - 36 meses.

Burning mouth syndrome (BMS) is defined as a burning sensation mainly on the tongue, palate and/or gingival or in any other region of the oral mucosa, in the absence of specific oral lesions. BMS is typically characterized by a continuous, spontaneous, and often intense burning sensation as if the mouth or tongue were scaled or on fire. The etiology of this disorder is poorly understood even though new evidence of involvement of neurological, emotional and hormonal alterations. The correct diagnosis of BMS and the exclusion of possible local or systemic factors that can be associated with the symptoms are fundamental. It is most common among postmenopausal women and causes intense discomfort and suffering. This condition often affects the health related quality of life in patients. Tricyclic antidepressants, benzodiazepines and antipsychotic drugs are the most accepted options in treatment and show variable results. The aims of this study were to investigate the action of homeopathy treatment in the symptomatological burning mouth syndrome in two phases: double-blind placebo controlled study and open trial study. Association of BMS with level of anxiety and depression had been considered. This study comprised data from 31 patients diagnosed with BMS in the outpatients Clinic of the Department of Stomatology, FOUSP, between July, 2011 and September, 2012. Thirty-one patients (25 women, 6 men median age 58.93 years, range 34-85), were randomized in two groups G1 (Arsenicum album) and G2 (Placebo) during 90 days, with washout for 30 days (PHASE 1).The oral symptoms and the treatment response were assessed using visual analogue scale (VAS) before and after the treatment and the global perceived effect (GPE) score using 5 point scale at the end of the PHASE 1. The level of burning reduction assessed by VAS was significant (44.50% with Arsenicum album and 12.65% with Placebo). In the PHASE 2, twenty-eight patients that participate of the PHASE 1.

Investigation of factors associated with treatment-seeking in Southern Chinese with orofacial pain.

AIMS: To investigate key factors associated with treatment-seeking for orofacial pain symptoms in community-dwelling adult Chinese people in Hong Kong. METHODS: A cross-sectional study was conducted using a Hong Kong Hospital Authority Family Medicine Clinic as the sampling frame. People aged 35 to 70 years with recent orofacial pain symptoms participated. Standard questions were asked about orofacial pain symptoms and characteristics in the previous month, Oral Health Impact Profile (OHIP-14), General Health Questionnaire (GHQ-12), Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) depression/nonspecific physical symptoms (NPS) scales, sleep and illness behavior measures, and questions on pain disability, professional treatment-seeking, pain medication usage, and dental attendance were administered prior to a standard clinical assessment. Multiple logistic regression with a forward stepwise selection method was used for data analysis. RESULTS: Two hundred people with orofacial pain symptoms participated in the definitive study. Twenty-seven percent had sought professional advice. The majority had consulted a medical practitioner (66.7%) or dentist (40.7%), 16.7% had consulted a traditional Chinese medicine (TCM) practitioner, and the majority (60%) had taken pain medication. There was no significant association between different orofacial pain diagnoses and professional treatment-seeking (P = .602). Four independent factors were significantly related to an increased likelihood of treatment-seeking (P < .05): more frequent dental attendance for check-up (odds ratio [OR] > 3), time when pain was experienced during the past month (days) (OR > 5), multiple pain symptoms (OR = 4.99), and use of TCM when ill (OR = 3.31). CONCLUSION: Professional treatment-seeking for orofacial pain was low in this ethnic group. The strongest predictor of treatment-seeking for orofacial pain was an increase in the number of days when pain was experienced during the past month. Key factors associated with treatment-seeking should be considered when formulating community health outreach programs. A further validation study with a larger sample size is recommended to confirm the present findings.

Síndrome de ardência bucal: estudo dos fatores clínicos associados ao diagnóstico e avaliação da acupuntura como modalidade terapêutica / Burning mouth syndrome: study of clinical factors associated with diagnosis and evaluation of acupuncture as a therapeutic modality

A síndrome de ardência bucal (SAB) é classicamente descrita como uma doença orofacial crônica, caracterizada pela presença do sintoma de ardência ou queimação na mucosa oral clinicamente normal. A SAB possui significativa predileção pelo gênero feminino e alta prevalência em indivíduos acima dos 40 anos de idade. Sua etiologia, embora desconhecida, é considerada multifatorial e, frequentemente, associada a fatores locais, sistêmicos, psicogênicos e neuropáticos. Diversos tratamentos são propostos para a SAB, porém considerados empíricos e ineficazes. Os objetivos do presente estudo foram investigar os fatores associados ao diagnóstico da SAB e a eficácia da acupuntura como modalidade terapêutica. Os dados de 95 pacientes diagnosticados com SAB no ambulatório da Disciplina de Estomatologia Clínica da FOUSP no período de Janeiro de 1993 a Fevereiro de 2005 foram avaliados retrospectivamente. Os critérios de inclusão e exclusão considerados no diagnóstico da SAB foram estabelecidos pela queixa de ardência bucal e ausência de sinais clínicos visíveis na mucosa oral. A relação entre os fatores prognósticos (classificação, localização, intensidade, natureza e escore EVA) e os fatores associados (xerostomia, hipossalivação, pH salivar, candidose bucal, prótese dentária removível, comorbidades, medicação sistêmica, ansiedade, depressão, estresse, cancerofobia, idade, gênero, etnia, e hábitos), foi analisada estatisticamente através do teste exato de Fisher, Regressão de Poisson univariada e multivariada e o teste de Mann-Whitney. Para a análise da resposta terapêutica da acupuntura foi utilizado o teste de Wilcoxon para verificar diferenças entre a sintomatologia avaliada através de EVA (0-100), intensidade (suave-moderada-grave) e frequência (intermitente-contínua), antes e depois do tratamento acupuntura.

O nível de significância de 5% (p<0,05) foi considerado.

Os resultados obtidos evidenciaram significativa predileção da SAB pelo gênero feminino, presente em 87 (91,58%) mulheres, especialmente de etnia Caucasiana. A média de idade foi de 59,76 anos (32-86 anos), sendo mais prevalente na faixa etária entre 50 e 70 anos. Os Tipos 1 e 2 de SAB foram os mais prevalentes, e a língua foi o local mais afetado, referido por 79 (83,16%) pacientes. A média de duração dos sintomas foi de 3 anos (2 meses a 20 anos). O escore médio mensurado por EVA foi de 80,63 (30-100), sendo mais prevalentes os sintomas de intensidade grave e contínua. Os fatores mais frequentes foram: uso de medicações sistêmicas, constatado em 75 (78,95%) pacientes, comorbidades, em 73 (76,84%), e xerostomia, em 33 (34,74%) indivíduos. Dentre as inúmeras análises realizadas, não foi evidenciada qualquer correlação estatisticamente significativa (p>0,05) entre os fatores estudados e a SAB. Quanto à resposta terapêutica da acupuntura, evidências quanto à sua eficácia no tratamento da SAB foram constatadas pela diminuição estatisticamente significante no escore EVA (p<0,01), assim como verificado para a intensidade, que variou de grave a ausente (p<0,01), e para a frequência dos sintomas, variando de contínua a ausente ou intermitente (p<0,01), no período estudado. De acordo com os resultados obtidos no presente estudo, concluímos que fatores frequentemente associados à SAB não evidenciaram correlações significativas com esta síndrome em nossa casuística e que a acupuntura se mostrou eficaz na melhora da sintomatologia de ardência bucal referida pelos pacientes.

The correlation between prognostic factors (classification, location, intensity, nature and VAS score) and the associated factors (xerostomia, hyposalivation, salivary pH, oral candidiasis, removable dental prosthesis, comorbidities, systemic medication, anxiety, depression, stress, cancerophobia, age, gender, ethnicity, and habits), was statistically evaluated by means of Fisher exact test, Poisson regression univariate and multivariate analysis and the Mann-Whitney test.

To investigate the therapeutic response of acupuncture, the Wilcoxon test was used to identify differences between symptoms assessed by VAS (0-100), intensity (mild-moderate-severe) and frequency (continuous-intermittent) before and after acupuncture treatment. The significance level of 5% (p<0.05) was considered. The results showed a significant preference of BMS in gender female, present in 87 (91.58%) women, especially Caucasian ethnicity. The mean age was 59.76 years (32-86 years), most prevalent between the ages of 50 and 70 years. Types 1 and 2 of BMS were the most prevalent, and the tongue was the most affected site, reported by 79 (83.16%) patients. The mean duration of symptoms was 3 years, ranging from 2 months to 20 years. Regarding symptom intensity, the mean score measured by VAS was 80.63 (30-100), and the most frequent symptoms were severe and continuous. Among of considered factors, the most frequent were: use of systemic

Terapia laser em baixa intensidade em pacientes portadores da Síndrome de Ardência Bucal: estudo randomizado e controlado / Low Level Light Therapy in Burning Mouth Syndrome patients: randomized and controlled trial

A Síndrome de Ardência Bucal (SAB) é uma condição de etiologia ainda desconhecida, caracterizada por ardência em mucosa oral na ausência de qualquer sinal clínico, cujo tratamento ainda é insatisfatório. O objetivo deste estudo foi avaliar a eficácia terapêutica do laser em baixa intensidade para pacientes SAB, por meio de estudo controlado e randomizado. Vinte e três pacientes acometidos pela SAB atenderam aos critérios de inclusão, cumpriram o protocolo estabelecido e tiveram seus dados tabulados e analisados. Fizeram parte da avaliação inicial dos pacientes, exame clínico estomatológico completo, sialometria, exames hematológicos e avaliação psicológica voltada à identificação da qualidade de vida e de sinais de depressão. Constituíram-se dois grupos experimentais, que receberam quatro irradiações, duas por semana, de laser em baixa intensidade - grupo Laser, ou de falsa irradiação - grupo Placebo. O aparelho usado foi um laser em baixa intensidade (Quantum, EccoFibras, Campinas-Brasil) de AsGaAl, emitindo 790 nm e com 120 mW de potência. As irradiações foram realizadas na forma de varredura, nas áreas de mucosa acometidas pelo sintoma de ardência, fornecendo uma dose de 6 J/cm2. Os pacientes foram alocados entre os grupos segundo programa de randomização por computador, sendo mantidos cegos quanto ao tipo de irradiação recebida (laser ou placebo). Os resultados foram coletados por pesquisadora auxiliar, que não teve conhecimento do tipo de irradiação efetuada, por meio de escala visual analógica (VAS) e escala de percepção global (EPG).

A pesquisadora principal não teve acesso aos resultados, antes do término do estudo. Os pacientes foram avaliados ao início do estudo, em cada um dos quatro tempos de irradiação e aos 7, 14, 30, 60 e 90 dias após a última irradiação. Os pacientes foram categorizados, de acordo com seu percentual de sintoma, ao final do último controle: sem ardência (S.A)- 0% de sintomatologia, ótimo (O)- 1% a 25%, bom (B)- 26%-50%, regular (R)- 51%-75%, inalterado (I)- 76-100% e piora (P)- valores superiores a 100%. A análise estatística apontou uma melhor resposta no grupo Laser (p=0,03; Teste Exato de Fisher). Concluiu-se que a terapia com laser em baixa intensidade, segundo o protocolo utilizado neste estudo, produz benefício aos pacientes portadores da síndrome de ardência bucal, sem apresentar qualquer efeito colateral indesejável, sugerindo o aprofundamento da pesquisa nesse campo.

Burning Mouth Syndrome (BMS) is a condition of unknown etiology, characterized by a burning sensation in the oral mucosa in the absence of any clinical sign, which treatment is still unsatisfactory. The aim of this study was to evaluate the effectiveness of low intensity laser therapy for SAB patients, through a randomized controlled clinical trial. Twenty-three patients affected by SAB met the inclusion criteria, complied with the established protocol and had their data analyzed. Patients initial evaluation comprised a complete clinical examination, unstimulated salivary flow, hematological examination and psychological assessment focused on identifying the quality of life and signs of depression. Two experimental patients groups were constituted: a Laser group and a Placebo group, which received four irradiations, two per week, of low intensity laser or false irradiation, respectively. The laser device utilized was a low intensity laser (Quantum, EccoFibras, Campinas, Brazil) GaAlAs, emitting 790 nm with120 mW of power. The irradiations were performed scanning the areas of mucosa affected by the burning sensation, delivering a dose of 6 J/cm2. Patients were allocated among the groups with the aid of a randomization computer program. Patients were kept blind to the type of radiation received (laser or placebo). The results were obtained by a researcher assistant, who was unaware of the type of irradiation effected, by means of a visual analogue scale (VAS) and a global perception scale (EPG).

The principal investigator had access to the results only at the end of the study. Patients were evaluated at baseline in each of the four times of irradiation and at 7, 14, 30, 60 and 90 days after the last irradiation. Patients were categorized according to their percentage of symptom at the end of last control: no burning (SA) - 0% of symptoms, optimal (O) - 1% to 25%, good (B) - 26% -50 %, regular (R) - 51% -75%, unchanged (I) - 76-100%, and worsening (P) - values exceeding 100%. Statistical analysis showed a better response in the laser group (p = 0.03, Fisher's exact test). It was concluded that low intensity laser therapy, according to the protocol applied in this study, produces benefit to patients with burning mouth syndrome, without any undesirable side effect, suggesting further research in this field.

Síndrome de ardor bucal: actualización diagnóstica y terapéutica / Burning mouth syndrome: diagnostic and therapeutic actualisation

El síndrome de boca ardiente (SBA) es una entidad patológica caracterizada por la presencia de síntomas crónicos de ardor o dolor en la mucosa bucal clínicamente normal. El SBA afecta principalmente a mujeres peri y posmenopáusicas. Su causa es desconocida, pero su relación con una compleja asociación de factores biológicos y psicológicos hace suponer una etiología multifactorial. Aunque se han encontrado tratamientos eficaces en casos particulares, se sigue buscando un tratamiento que resulte eficaz en la mayoría de los casos. Esta revisión hace especial referencia a los factores etiológicos y al tratamiento del síndrome (AU)

The burning mouth syndrome (BMS) is characterized by the presence of chronic symptoms of burning or paining clinically normal oral mucosa. This syndrome primarily affects peri and postmenopausal women. The cause is unknown, but the relationship between the BMS and a complex association of biological and psychological factors suggest a multifactorial etiology. Although some treatments have been found effective in particular cases, the clinical searchers are still looking for a treatment that can be effective in most cases. This review makes particular reference to the etiological factors and the treatment of the síndrome (AU)

Diagnosis and management of non-dental orofacial pain.

UNLABELLED: Careful history-taking improves diagnosis of non-dental orofacial pain, a not uncommon group of conditions. Accurate diagnosis of conditions such as chronic idiopathic facial pain, temporomandibular disorders, burning mouth syndrome and trigeminal neuralgia is essential if inappropriate dental treatment is to be avoided. There are few investigations to help in the diagnostic process and many of these patients have other forms of chronic pain. All the conditions are best treated using a holistic approach. Drugs, such as tricyclic antidepressants and anticonvulsants, are often effective and surgery can be highly successfully in trigeminal neuralgia. Patient education is paramount. CLINICAL RELEVANCE: Although the majority of pain seen in general dental practice is dental in origin, chronic non-dental orofacial pain must be recognized as its management is entirely different.
