Clinical Research on Rett Syndrome: Central Hypoxemia and Hypokalemic Metabolic Alkalosis.

Background: Rett syndrome (RTT) is now widely recognized as a profound neurological disorder that predominantly affects females and is closely associated with mutations in the methylated CpG binding protein 2 (MECP2) gene located on the X chromosome. The Characteristic symptoms of RTT include the loss of acquired language and motor skills, repetitive hand movements, irregular breathing, and seizures. Additionally, RTT patients may experience sporadic episodes of gastrointestinal problems, hypoplasia, early-onset osteoporosis, bruxism, and screaming episodes. It is worth noting that males exhibit a unique and variable phenotype, though rare in RTT cases, often accompanied by severe manifestations. Case Presentation: In this report, we present the case of a young male child with a de novo c.806delG hemizygous mutation, leading to an atypical presentation of RTT that remarkably mirrors the clinical features of Bartter syndrome, a genetic metabolic disorder. The clinical manifestations in this case included the loss of previously acquired language and motor skills, repetitive hand movements, breathing irregularities, seizures, sporadic episodes of gastrointestinal distress, hypoplasia, early-onset osteoporosis, bruxism, and episodes of screaming. This distinctive presentation underscores the complex diagnostic landscape of RTT, particularly in males, and highlights the need for vigilant clinical evaluation. Conclusions: This case report sheds light on an unusual and atypical presentation of RTT in a young male child with a de novo c.806delG hemizygous mutation. The resemblance of clinical features to Bartter syndrome underscores the diagnostic challenges posed by RTT and highlights the importance of comprehensive clinical assessment and genetic testing, especially in cases deviating from the typical RTT phenotype. Our findings contribute valuable insights into the early diagnosis and management of atypical RTT presentations.

Effectiveness of Biofeedback in Individuals with Awake Bruxism Compared to Other Types of Treatment: A Systematic Review.

Excessive masticatory muscle activity is generally present in awake bruxism, which is related to increased anxiety and stress. It has been hypothesized that biofeedback could potentially manage awake bruxism, however, its effectiveness has not been empirically analyzed in a systematic manner. Therefore, this systematic review was designed to determine the effectiveness of biofeedback compared to other therapies in adults with awake bruxism. Extensive searches in five databases looking for randomized controlled trials (RCTs) that included biofeedback to manage awake bruxism were targeted. The risk of bias (RoB) assessment was conducted using the Cochrane RoB-2 tool. Overall, four studies were included in this systematic review, all of which used the electromyographic activity of the masticatory muscles during the day and night as the main endpoint. Auditory and visual biofeedback could reduce the excessive level of masticatory muscle activity in a few days of intervention. The majority of the included studies had a high RoB and only one study had a low RoB. The standardization of the biofeedback protocols was also inconsistent, which makes it difficult to establish the ideal protocol for the use of biofeedback in awake bruxism. Thus, it is proposed that future studies seek to reduce methodological risks and obtain more robust samples.

Biofeedback no controle do bruxismo: uma revisão de escopo / Biofeedback for the control of bruxism: a scoping review

Objetivo: Compreender como os diversos tipos de biofeedback agem, e se são eficazes no controle do bruxismo do sono e vigília. Métodos: trata-se de uma revisão de escopo, com busca em três bases de dados, Medline (Pubmed e BVS), PEDRo e Cochrane, e redigida de acordo com as diretrizes do PRISMA-ScR. Resultados: Foram encontradas 595 referências. Após a remoção das duplicatas e da aplicação dos critérios de elegibilidade, trinta e cinco artigos foram incluídos. A maioria investigou o bruxismo do sono e o uso de placas orais integradas a sistemas de biofeedback, principalmente através de estímulos exteroceptivos. Na maioria dos artigos, o biofeedback foi efetivo a curto prazo para o bruxismo do sono, reduzindo a duração dos episódios, mas não alterando o número de episódios do bruxismo, mas com retorno aos níveis do pré-tratamento. O uso do biofeedback foi mais efetivo para o bruxismo de vigília e nos estudos que investigaram ambos os tipos de bruxismo, mas, com o uso do biofeedback apenas no período diurno, foi possível observar uma redução tanto nos eventos do bruxismo de vigília como nos do sono. Conclusão: A maioria das pesquisas se utilizou do biofeedback por meio de estímulo exteroceptivo, com reforço negativo a um estímulo aversivo; poucos estudos utilizaram o biofeedback com o propósito de condicionamento motor ou de mudança comportamental, sendo esses mais eficazes, mesmo após a retirada do estímulo.

Aim:To comprehend the functioning of various biofeedback types and their effectiveness in controlling sleep and awake bruxism. Methods: This is a scoping review, conducted in three databases: Medline (Pubmed and VHL), PEDRo, and Cochrane, and was written according to PRISMA-ScR guidelines. Results: Our study found 595 references; after removing duplicates and applying the eligibility criteria, thirty-five articles were included. Most studies examined the effectiveness of biofeedback systems that integrated oral splints, primarily through the use of exteroceptive stimuli, to manage sleep bruxism. Although biofeedback was found to reduce the duration of bruxism episodes in the short term in most articles, it did not significantly change the number of episodes, which reverted to pre-treatment levels. The use of biofeedback was more effective for awake bruxism. Moreover, in the studies that investigated both types of bruxism, but with the use of biofeedback only during the day, it was possible to observe a reduction in both the events of awake and sleep bruxism. Conclusion: Most studies used biofeedback with negative reinforcement through exteroceptive stimulation to an aversive stimulus. Few studies use biofeedback for motor conditioning or behavioral change. The latter approaches proved to be more effective, even after discontinuing the stimulus.

Masseter Muscle Thickness And Elasticity in Bruxism After Exercise Treatment: A Comparison Trial.

OBJECTIVE: The purpose of this study was to evaluate the effects of Rocabado's 6 × 6 exercises on masseter muscle thickness, muscle elasticity, and pain scores in patients with bruxism. METHODS: A total of 58 participants with bruxism were divided into 2 groups as the exercise group (EG) and control group (CG). A self-care program was applied for the participants in the CG. For those in the EG, in addition to the self-care program, an exercise treatment was performed for 6 days per week for a total of 8 weeks. Using ultrasonography, bilateral masseter muscle thickness and elasticity were assessed before and after treatment. Pain was measured using a visual analog scale. Changes over time within the groups and group-time interactions for continuous variables were assessed using mixed 2-way repeated measures analysis of variance. RESULTS: The improvement in muscle elasticity (P = .015; P = .004) and pain values (P = .049; P = .040) were greater in the EG compared with the CG. There was no significant difference between the 2 groups for masseter muscle thickness (P > .05). CONCLUSION: This study suggests that Rocabado's 6 × 6 exercises are effective in the treatment of muscle elasticity and pain values in participants with bruxism.

Cannabis. Usos y aplicaciones en la práctica odontológica diaria: revisión de la literatura / Cannabis. Uses and applications in daily dental practice: a review of the literature

La evidencia científica presente en la literatura indica que el cannabis puede ser utilizado con fines terapéuticos para tratar distintas afecciones odontológicas. Dado el acceso sencillo a la cavidad bucal, las distintas formulaciones de cannabis pueden aplicarse de forma tópica. La aplicación local de dosis bajas de cannabis ha demostrado alta efectividad para tratar distintas afecciones bucales, constituyendo un tratamiento seguro con baja probabilidad de generar repercusiones sistémicas indeseadas. En la actualidad, está siendo incorporado a materiales convencionales de uso e higiene odontológica con la finalidad de aprovechar sus efectos terapéuticos. El cannabis tiene múltiples usos en odontología: como componen-te de enjuagues bucales y soluciones para la desinfección de conductos radiculares, en tratamientos de trastornos de ansiedad bucal, como complemento en terapias oncológicas, como analgésico para atenuar el dolor inflamatorio y el neuropático, como miorrelajante y condroprotector para tratar trastornos de articulación témporomandibular (ATM) y bruxismo, como osteomodulador para el tratamiento de patologías que comprometen la integridad ósea, como la enfermedad periodontal y la osteoporosis, y para la cicatrización ósea asociada a fracturas, extracciones dentarias e implantes, y como inmunomodulador con potencial terapéutico para tratar patologías autoinmunes como las enfermedades reumáticas. El trata-miento local con cannabis es efectivo, bien tolerado por el paciente y con pocos efectos adversos. Por lo tanto, se puede concluir que el cannabis aporta un enorme abanico de posibilidades terapéuticas para tratar distintas afecciones odontológicas, aunque aún se requiere mayor cantidad de estudios científicos que avalen su utilización en cada situación fisiopatológica particular (AU)

The scientific evidence present in the literature indicates that cannabis can be used for therapeutic purposes to treat different dental conditions. Given the easy access to the oral cavity, the different cannabis formulations can be applied topically. The local application of low doses of cannabis has shown high effectiveness in treating different oral conditions, constituting a safe treatment with a low probability of generating unwanted systemic repercussions. It is currently being incorporated into conventional materials for dental use and hygiene in order to take advantage of its therapeutic effects. Cannabis has multiple uses in dentistry: as a component of mouthwashes and solutions for disinfecting root canals, in the treatment of oral anxiety disorders, as a complement in oncological therapies, as an analgesic to reduce inflammatory and neuropathic pain, as a muscle relaxant and chondroprotective to treat temporomandibular joint disorders and bruxism, as an osteomodulator for the treatment of pathologies that compromise bone integrity, such as periodontal disease and osteoporosis, and or bone healing associated with fractures, dental extractions and implants, and as immunomodulator with therapeutic potential to treat autoimmune pathologies such as rheumatic diseases. Local treatment with cannabis is effective, well tolerated by the patient and with few adverse effects. Local treatment with cannabis is effective, well tolerated by the patient and with few adverse effects. Therefore, it can be concluded that cannabis provides an enormous range of therapeutic possibilities to treat different dental conditions, although more scientific studies are still required to support its use in each particular pathophysiological situation (AU)

Comparison of Kinesio Taping and manual therapy in the treatment of patients with bruxism using shear-wave elastography-A randomised clinical trial.

BACKGROUND: Bruxism is significantly associated with craniofacial pain, feeling of stiffness or fatigue of the jaw and neck pain. Various physiotherapeutic strategies are used in the treatment of bruxism; however, it is not clear which method leads to greater decrease in pain. OBJECTIVE: The aim of this study is to compare the effects of two physiotherapy methods (manual therapy [MT] and Kinesio taping with manual therapy [KTMT]) in patients with bruxism. METHODS: Patients were randomised into MT or KTMT groups. Evaluations were performed at baseline and following 4 weeks of physiotherapy. Muscle thickness and stiffness were assessed via shear wave elastography; pain thresholds were evaluated using algometer. Sleep quality was assessed using Pittsburgh Sleep Quality Index, and quality of life was assessed with Likert scales regarding the associated symptoms. RESULTS: Significant decreases were found in muscle stiffness, pain threshold, sleep quality and quality of life (P < .05) in both MT and KTMT groups. Pain in bilateral temporalis and right occipital region of the trapezius muscle decreased more in the KTMT group compared with the MT group (P < .05). No significant differences in muscle thickness (P > .05) were found in either of the groups. CONCLUSION: Both MT and KTMT methods were effective in the treatment of bruxism. Kinesio Tape used in conjunction with MT has additionally decreased jaw pain and temporal region pain compared with MT intervention only. Therefore, if jaw pain is the primary complaint of a patient, our results recommend including Kinesio Tape application in the physiotherapeutic treatment program.

One year into the COVID-19 pandemic - temporomandibular disorders and bruxism: What we have learned and what we can do to improve our manner of treatment.

The coronavirus disease 2019 (COVID-19) pandemic has drastically changed the routine way of life and challenged the ways in which health and dental services are provided. During the 1st lockdown, practiced in most of the countries, routine dental procedures were suspended. Even after the lockdown was eased, visiting crowded dental clinics was still considered health-threatening, especially among populations at high risk of developing a severe reaction to COVID-19. Regretfully, in most cases, temporomandibular disorders (TMD) and bruxism were not included under the definition of emergency, leaving many patients without the possibility of consulting their dentists. A literature search, performed about 10 months after the declaration of the pandemic, found only a few studies dealing with TMD and bruxism during COVID-19. Most of the studies indicate adverse effects on subjects' psycho-emotional status (stress, anxiety, depression), which in turn lead to the intensification of subjects' TMD and bruxism symptoms, and increased orofacial pain. Unlike other oral pathologies, which require manual interventions, chronic orofacial pain can be addressed, at least at its initial stage, through teledentistry and/or consultation. Remote first aid for patients suffering from orofacial pain includes various kinds of treatment, such as the self-massage of tense and painful areas, stretching, thermotherapy, drug therapy, relaxation techniques, meditation, and mindfulness, all of which can be administered through the phone and/or the Internet. Relevant legal and ethical issues should be considered while using remote modes for the triage, diagnosis and treatment of chronic orofacial pain patients.

Self-reported sleep bruxism is associated with vitamin D deficiency and low dietary calcium intake: a case-control study.

BACKGROUND: Sleep bruxism may result in deleterious effects including loss of tooth enamel, fracture of teeth or restorations, teeth hypersensitivity or pain, and headache. The aim was to study the link between sleep bruxism, low serum vitamin D, low consumption of dietary calcium, psychological symptoms, and frequent headache. METHODS: This case-controlled study included 50 individuals with sleep bruxism and 50 age and gender matched controls. 25-hydroxyvitamin D was measured in serum. Hospital Anxiety and Depression Scale was used to measure anxiety and depression. Data about dietary calcium and frequent headache were self-reported. RESULTS: Participants with sleep bruxism had lower 25-hydroxyvitamin D and higher scores of anxiety and depression compared to controls (p < 0.05). Vitamin D deficiency, abnormal scores of anxiety and depression, low calcium consumption (< 323 mg/day), and frequent headache were reported in higher % of individuals with sleep bruxism compared to controls (p < 0.05). Binary logistic regression showed that sleep bruxism was significantly associated with vitamin D deficiency (OR = 6.66, p = 0.02), low consumption of dietary calcium (OR = 5.94, p = 0.01), and frequent headache (OR = 9.24, p < 0.001). Multiple linear regression showed that anxiety was significantly associated with decreased 25-hydroxyvitamin D (p = 0.03), increased scores of depression (p < 0.001) and female sex (p = 0.01). Binary logistic regression also showed that frequent headache was significantly associated with sleep bruxism (OR = 5.51, p < 0.01). CONCLUSIONS: Sleep bruxism was associated with vitamin D deficiency and low consumption of calcium and was also associated with increased scores of anxiety and depression. Further investigations should be performed to check if vitamin D and calcium supplementation could relieve sleep bruxism.

Bruxismo en la infancia: ¿cómo tratar? / Bruxismo na infância: como tratar? / Bruxism in childhood: how to treat?

El bruxismo infantil es una condición definida por la acción de apretar o rechinar los dientes involuntariamente, siendo así de etiologia multifactorial. Cuando no es tratado tempranamente, puede causar daño al sistema estomatognático, causando cambios orofaciales. De esta forma, este artículo tiene como objetivo abordar las diferentes opciones de tratamiento para el bruxismo en niños. Esta es una revisión integradora realizada a través de las bases de datos SciELO y PubMed, la cual incluye un total de 14 artículos, respetando los criterios de inclusión y exclusión. En general, el tratamiento debe ser cumplido realizado de manera multidisciplinaria, incluyendo la incorporación del cirujano dentista, doctor, psicólogo, fisioterapeuta y logopeda para mejorar la calidad de vida del individuo. A través de la exclusión de los posibles factores que determinan la enfermedad, tiene como objetivo promover la reducción de la actividad parafuncional. Para lograr eso, podemos usar placas oclusales, medicamentos como analgésicos, antiinflamatorio, benzodiacepinas, relajantes musculares, además de las hierbas medicinales, así como también, terapia de masaje, criolipólisis, acupuntura, entre otros. Sin embargo, mas estudios son necesarios para probar la efectividad de estas terapias. Se puede concluir que hasta el momento presente, lo que se puede ofrecer es un tratamiento paliativo y multidisciplinario que permite la reducción de complicaciones patológicas, favoreciendo así, la salud del niño.

O bruxismo infantil é uma condição definida pela ação de apertar ou ranger os dentes de forma involuntária sendo de etiologia multifatorial. Quando não interferida precocemente pode gerar danos ao sistema estomatognático, ocasionando alterações orofaciais. Dessa forma, o presente artigo tem como objetivo abordar as diferentes opções de tratamento para o bruxismo em crianças. Trata-se de uma revisão integrativa realizada por meio das bases de dados SciELO e PubMed, foram incluídos um total de 14 artigos, respeitando os critérios de inclusão e exclusão. De forma geral, o tratamento deve ser realizado multidisciplinarmente, englobando a adição do cirurgião-dentista, médico, psicólogo, fisioterapeuta e fonoaudiólogo, com intuito de proporcionar melhora da qualidade de vida ao indivíduo. Através da exclusão dos possíveis fatores determinantes da doença, visa-se a promoção da redução da atividade parafuncional. Para isso, pode-se lançar mão de placas oclusais, medicamentos, como analgésicos, anti-inflamatórios, benzodiazepínicos, relaxantes musculares, além de fitoterápicos, bem como, massagem terapêutica, criolipólise, acupuntura, entre outros. Contudo, é necessário que mais estudos comprovem a eficácia dos referidos terapêuticos. Assim sendo, conclui-se que até o presente momento, o que se pode oferecer é um tratamento paliativo e multidisciplinar que possibilite a diminuição das complicações patológicas e desta forma favorecendo o estado de saúde da criança.

The bruxism in the childhood is a multifactorial condition defined by the act of involuntarily clenching or grinding the teeth. When not interfered early can cause damage to the stomatognathic system, causing orofacial changes. Thus, this article aims to address the different treatment options for bruxism in children, this is an integrative review conducted through the SciELO and PubMed databases, a total of 14 articles were included, respecting the inclusion and exclusion criteria. In general, the treatment should be performed in a multidisciplinary manner, including the addition of the dental surgeon, physician, psychologist, physiotherapist and speech therapist, in order to improve the quality of life of the individual. By excluding possible determinants of the disease, the aim is to promote the reduction of parafunctional activity. For this, it can use occlusal plaques, medications such as analgesics, anti-inflammatory drugs, benzodiazepines, muscle relaxants, as well as herbal medicines, as well as massage therapy, cryolipolysis, acupuncture, among others. However, further studies need to prove the effectiveness of such therapies. Therefore, it can be concluded that, until now, what can be offered is a palliative and multidisciplinary treatment thatenables the reduction of pathological complications and thus favoring the child's health status.

Is Biofeedback through an Intra-Aural Device an Effective Method to Treat Bruxism? Case Series and Initial Experience.

Biofeedback was reported as an effective concept for bruxism treatment, through increasing patient's awareness of the habit. During bruxing both ear canals become tighter, therefore, an in-ear device can provide biofeedback. The in-ear device is fitted to the ear canal in physiological status, during bruxing the ear-canal tightens resulting in stress on the canal walls and unpleasant feeling. Subsequently, patients stop their bruxing habit. The aim of this study is to provide first clinical evidence that in-ear devices have a positive impact on relieving bruxism in patients. Despite the low number of patients, this early study was designed as a controlled prospective study. The trial included seven female patients with a median age of 47.3 years (23-64 years). Only two patients implemented their devices for eight and seven months, respectively. One patient reported a relief in her symptoms, like headaches and pain intensity during the night, by 50% after three month and 80% after six months. Despite the limited number of participants, the study reflects a potential of Intra-aural devices as effective biofeedback devices in treating bruxism.

Auriculotherapy for sleep bruxism in children: a series of cases

Sleep bruxism is defined as a behavior that causes masticatory muscle activities during sleep. Sleep bruxism in childhood leads to consequences, which may vary from teeth wear in deciduous dentition to temporomandibular disfunction symptoms. There's no data that demonstrates improvement of children with sleep bruxism during and after auricular acupuncture treatment. Objective: Therefore, this case report series aimed to evaluate the effect of auriculotherapy on children presenting sleep bruxism. Methods: Twelve patients were included in this study, in the mean age of 6,9. The diagnosis was evaluated by the question: "Does your kid grind their teeth while sleeping?". Treatment was performed by an acupuncture specialist in a standardized way. The therapy was given for three weeks and the effect was evaluated through a sleep diary, in which the parents noted whether or not their child grinded teeth while sleeping before (baseline) and during therapy (T1 to T3). Sleep bruxism was categorized as presence or absence of nocturnal teeth grinding and the frequency varied from 0 to 7 (baseline), 0 to 5 (T1), 0 to 7 (T2) and 0 to 4 (T3) between patients. The intensity of the reported sleep bruxism was compared according to the periods by pared T-test ( =0.05). Results: It was observed that the frequency of reports decreased significantly from baseline to T3. Conclusion: These results suggest that ear acupuncture may be an alternative therapy for sleep bruxism in childhood, once it demonstrated to reduce its frequency in this study, although patients may present different effects to therapy due to biological variability.

Introdução: Bruxismo do sono é definido como um comportamento que causa atividades musculares durante o sono. Na infância, leva a consequências que podem variar de desgaste dentário na dentição decídua a sintomas de disfunção temporomandibular. Não há estudos que demonstrem melhora de casos de crianças com bruxismo do sono durante e após tratamento com auriculoterapia. Objetivo: portanto, esta série de casos visou avaliar o efeito da auriculoterapia em crianças apresentando este quadro. Métodos: Doze pacientes foram inclusos neste estudo, com a media de idade de 6,9. O diagnóstico foi avaliado pela pergunta "Seu filho range os dentes quando dorme?". O tratamento foi executado por um especialista em acupuntura de forma padronizada. A terapia foi feita por três semanas e o efeito foi avaliado através de um diário do sono, no qual os pais anotavam se a criança rangeu os dentes enquanto dormia antes (baseline) e durante a terapia (T1 a T3). Bruxismo do sono foi categorizado como presença ou ausência de ranger de dentes e a frequência variou de 0 a 7 (baseline), 0 a 5 (T1), 0 a 7 (T2) e 0 a 4 (T3) entre os pacientes. A intensidade foi comparada de acordo com os períodos pelo teste-T pareado (=0,05). Resultados: Foi observado que a frequência de relatos diminuiu significativamente de baseline a T3. Conclusão: Estes resultados sugerem que auriculoterapia pode ser uma terapia alternativa para o bruxismo do sono na infância, uma vez que demonstrou reduzir sua frequência neste estudo, embora os pacientes possam apresentar efeitos diferentes devido à variabilidade biológica.

Music Modulates Awake Bruxism in Chronic Painful Temporomandibular Disorders.

OBJECTIVE: In this experimental study, we aimed to determine whether guided music listening (GML) - a music intervention based on models of mood mediation and attention modulation - modulates masticatory muscle activity and awake bruxism in subjects with chronic painful muscular temporomandibular disorders (TMD myalgia, mTMD), a condition causing a significant burden to patients, their families, and healthcare systems. BACKGROUND: Awake bruxism - a stress behavior characterized by clenching of the teeth - is a strong contributor to chronic mTMD. GML modulates psychological stress and motor responses and could thus reduce muscle activity in chronic musculoskeletal conditions, including mTMD. METHODS: We recorded the electromyographic (EMG) activity in the right masseter of 14 women with chronic (>6 months) mTMD (median [IQR] = 39.5.3 [24.3] years) and 15 pain-free women (median [IQR] = 30.0 [3.5] years) during a GML session, including 3 music (stressful, relaxing, and participants' favorite music) and a no-music (pink noise) control blocks, each lasting 15 minutes. We measured the motor effort of the right masseter relative to the participants' maximum voluntary contraction (MVC), the muscular effort to maintain mandibular posture (EMGposture ), and to produce spontaneous awake bruxism episodes (EMGbruxism ), and the duration and frequency of spontaneous awake bruxism episodes. We tested between-group and within-group (between blocks) differences, as well as the effect of the interaction group by experimental block on these outcome measures. RESULTS: In both groups, EMGposture was significantly affected by the interaction group by experimental block (P < .001). Compared to pink noise [mean (95% CI); mTMD: 2.2 (1.6-2.8) %MVC; Controls: 1.1 (0.5-1.7) %MVC], EMGposture increased during the stressful music block [contrast estimate (95% CI); mTMD: +0.8 (0.7-0.8) %MVC; Controls: +0.3 (0.3-0.4) %MVC; both P < .001], and decreased during the relaxing [mTMD: -0.4 (-0.5 to -0.4) %MVC; Controls: -0.3 (-0.4 to -0.3) %MVC; both P < .001] and favorite [mTMD: -0.5 (-0.6 to -0.5) %MVC; Controls: -0.5 (-0.5 to -0.4) %MVC; both P < .001] music blocks. EMGposture was greater in mTMD individuals than controls during the favorite music [contrast estimate (95% CI): +1.1 (0.2-1.9) %MVC; P = .019] and the pink noise [+1.1 (0.2-2.0) %MVC; P = .014] blocks. EMGbruxism was significantly affected by the interaction group by experimental block (P < .001). In mTMD participants, compared to the pink noise block [mean (95% CI); 23.8 (16.0-31.6) %MVC], EMGbruxism increased during the stressful music block [contrast estimate (95% CI); +10.2 (8.6-11.8) %MVC], and decreased during the relaxing [-6.2 (-8.1 to -4.3) %MVC; P < .001] and favorite [-10.2 (-12.2 to -9.1) %MVC; P < .001] music blocks. These effects were not observed in the control group [mean (95% CI); pink noise: 19.3 (10.9-27.6); stressful: 21.2 (12.9-29.4) %MVC; relaxing: 21.6 (13.3-29.9) %MVC; favorite: 24.2 (15.8-32.7) %MVC; all P > .05]. EMGbruxism was significantly greater in mTMD participants than controls during the stressful music block [contrast estimate (95% CI): +12.9 (1.6-24.2) %MVC; P = .026). GML did not affect the duration or the frequency of awake bruxism in either group (median [IQR], mTMD: 23.5 [96.7] s, range 1-1300 seconds; Controls: 5.5 [22.5], range 0-246 seconds; P = .108). The frequency of awake bruxism episodes was greater in the mTMD group compared to controls only during the pink noise block (median [IQR], mTMD: 5 [15.3] episodes, range 0-62 episodes; Controls: 1 [3] episode, range 0-27 episodes; P = .046). No significant between-group differences were found in either the overall time spent engaging in awake bruxism (median [IQR], mTMD: 23.5 [96.7] s, range 1-1300 seconds; Controls: 5.5 [22.5], range 0-246 seconds; P = .108), or during each block (all P > .05). CONCLUSIONS: In subjects with chronic mTMD, relaxing music and the individual's favorite music decreased the muscular effort during spontaneous awake bruxism episodes by 26% and 44% (relative changes), respectively. In contrast, stressful music increases it by about 43%. Because of its positive effects on awake bruxism, GML with selected music could be a promising and non-invasive component of a multimodal approach for the management of chronic mTMD.

A new biofeedback approach for the control of awake bruxism and chronic migraine headache: utilization of an awake posterior interocclusal device.

BACKGROUND: The relationship of bidirectional comorbidity between chronic migraine and pain in the cephalic segment led us to evaluate the improvement in reducing the pain in patients diagnosed with chronic migraine headache and awake bruxism, when undergoing treatment with a partial posterior interocclusal device designed for the management and control of awake bruxism through biofeedback. METHODS: Seventy-four patients were evaluated during the following periods: pretreatment, seven, thirty, ninety, one hundred and eighty days, and one year. The evaluation was carried out by measuring the pain in the pretreatment period and pain reduction after awake bruxism treatment, using clinical evaluation and numerical scales for pain. RESULTS: Most of the patients who complained of headache migraine pain, masticatory myofascial pain, temporomandibular joint and neck pain experienced a significant reduction in overall pain, including headaches, between t0 and t30 (p<0.0001). After 30 days of using the device, it was observed that the improvement remained at the same level without any recurrence of pain up to t90. At t180 and t360, it was observed that even with the device withdrawal (at t90) the improvement remained at the same level. CONCLUSION: The utilization of a posterior interocclusal device designed for the management and control of awake bruxism through biofeedback seems to contribute to the reduction of pain (including migraine headache) in the majority of patients, and, even with the device withdrawal (at t90), the improvement remained at the same level, suggesting the patients succeeded in controlling their awake bruxism and consequently the pains.

A new biofeedback approach for the control of awake bruxism and chronic migraine headache: utilization of an awake posterior interocclusal device / Uma nova abordagem via biofeedback para o controle do bruxismo de vigília e de enxaqueca crônica: utilização de um dispositivo interoclusal posterior em vigília

ABSTRACT Background: The relationship of bidirectional comorbidity between chronic migraine and pain in the cephalic segment led us to evaluate the improvement in reducing the pain in patients diagnosed with chronic migraine headache and awake bruxism, when undergoing treatment with a partial posterior interocclusal device designed for the management and control of awake bruxism through biofeedback. Methods: Seventy-four patients were evaluated during the following periods: pretreatment, seven, thirty, ninety, one hundred and eighty days, and one year. The evaluation was carried out by measuring the pain in the pretreatment period and pain reduction after awake bruxism treatment, using clinical evaluation and numerical scales for pain. Results: Most of the patients who complained of headache migraine pain, masticatory myofascial pain, temporomandibular joint and neck pain experienced a significant reduction in overall pain, including headaches, between t0 and t30 (p<0.0001). After 30 days of using the device, it was observed that the improvement remained at the same level without any recurrence of pain up to t90. At t180 and t360, it was observed that even with the device withdrawal (at t90) the improvement remained at the same level. Conclusion: The utilization of a posterior interocclusal device designed for the management and control of awake bruxism through biofeedback seems to contribute to the reduction of pain (including migraine headache) in the majority of patients, and, even with the device withdrawal (at t90), the improvement remained at the same level, suggesting the patients succeeded in controlling their awake bruxism and consequently the pains.

RESUMO Introdução: A relação de comorbidade bidirecional entre enxaqueca crônica e dor no segmento cefálico nos levou a avaliar a melhora na redução da dor em pacientes diagnosticados com cefaleia crônica de enxaqueca e bruxismo de vigília, quando submetidos a tratamento com dispositivo interoclusal posterior parcial projetado para o manejo e o controle do bruxismo acordado através de biorretroalimentação (biofeedback). Métodos: Setenta e quatro pacientes foram avaliados durante os seguintes períodos: pré-tratamento, sete, trinta, noventa e cento e oitenta dias, e um ano. A avaliação foi realizada por meio da avaliação da dor no período pré-tratamento e redução da dor após o tratamento do bruxismo de vigília, através de avaliação clínica e escalas numéricas de dor. Resultados: A maioria dos pacientes que se queixou de dor de cabeça com enxaqueca, dor miofascial mastigatória, articulação temporomandibular e dor no pescoço sofreu uma redução significativa na dor geral, incluindo dores de cabeça, entre t0 e t30 (p<0,0001). Após 30 dias de uso do dispositivo, observou-se que a melhora permaneceu no mesmo nível, sem recorrência da dor até t90. Em t180 e t360, observou-se que, mesmo com a retirada do dispositivo (em t90), a melhoria permaneceu no mesmo nível. Conclusão: A utilização de um dispositivo interoclusal posterior projetado para o controle do bruxismo de vigília através de biofeedback parece contribuir para a redução da dor (incluindo enxaqueca) na maioria dos pacientes, e, mesmo com a retirada do dispositivo (t90), a melhora manteve-se no mesmo nível, sugerindo que os pacientes conseguiram controlar o seu bruxismo de vigília e a dor associada a esse hábito.

On Psychosomatic Problems in Dentistry.

In their daily practice dentists frequently have patients showing signs of stress-related oral manifestations in different forms. Stress-related aetiology of oral changes are still not investigated enough, and present a subgroup of psychosomatic diseases which had been recognized in medicine a long time ago. Recognition of such psychological or emotional disturbance needs deep evaluation "per exclusionem", and is beneficial for both the patient and clinician. Psychological management should be taken into consideration when treating patients with these psychosomatic disorders. Therapeutic approach comprises different forms of psychotherapy and medication as well.

Effect of treatment with a full-occlusion biofeedback splint on sleep bruxism and TMD pain: a randomized controlled clinical trial.

OBJECTIVES: The purpose of the present study was to analyze treatment outcome with a full-occlusion biofeedback (BFB) splint on sleep bruxism (SB) and TMD pain compared with treatment with an adjusted occlusal splint (AOS). MATERIALS AND METHODS: Forty-one patients were randomly allocated to a test (BFB) or a control (AOS) group and monitored over a 3-month period. Output variables were frequency and duration of bruxing events (bursts) and various pain symptoms. RESULTS: The BFB group showed a statistically significant reduction in the frequency and duration of bursts and a statistically significant improvement in the patients' global well-being and the facial muscle pain parameter. After the treatment was stopped, the BFB group showed a statistically significant reduction in the average and maximum duration but no statistically significant change in the frequency of bursts. CONCLUSIONS: The tested BFB splint is highly effective in reducing SB at the subconscious level, i.e., without waking the patient, and in achieving improvements in global pain perception. The results suggest that the BFB splint also provides a better treatment option for bruxism-related pain than an AOS. However, further research is needed, and specifically studies with a larger patient population displaying higher levels of pain at baseline. CLINICAL RELEVANCE: By reducing burst duration and therefore the pathological load on the masticatory apparatus, the BFB splint reduces TMD and bruxism-related symptoms and improves patients' physical well-being. In the long term, this could prevent damage to the TMJ. This study confirms the effectiveness and safety of this splint.

Surface Electrical Stimulation for Persistent Stuttering and Concomitant Orofacial Disorders: A Multiple Case Study.

This multiple case study analysis describes the immediate effects on speech fluency of transcutaneous electrical nerve stimulation (TENS) applied to participants with persistent stuttering and concomitant orofacial disorders. Study participants were 14 adolescents and adults who stuttered and had jaw clenching bruxism or mouth breathing. Participants experienced low-frequency TENS applied at mild motor level for 20 minutes with electrodes placed at the lower third of the face (Area A), submandibular region (Area B), posterior neck (Area C), or shoulder girdle (Area D), with speech fluency assessed immediately before and after each stimulation.For participants with stuttering and bruxism, AB stimulation reduced the median frequency of syllables stuttered by 27% and reduced the median duration of the three highest stuttering moments by 29%. In addition, for participants with stuttering and mouth breathing, CD stimulation reduced the median duration of the three highest stuttering moments by 28% and increased their median speech rate by 113%. As a single session of TENS may help participants with stuttering and concomitant orofacial disorders better use fluency shaping techniques, the therapeutic potential of TENS for treating stuttering should be further investigated.

Daytime masticatory muscle electromyography biofeedback regulates the phasic component of sleep bruxism.

BACKGROUND: Electromyography (EMG) biofeedback (BF) training is potentially an effective cognitive-behavioural approach to regulate bruxism. OBJECTIVE: This study examined sleep bruxism regulation by daytime clenching control using a single-channel auditory EMG BF device. METHODS: Seventeen male subjects (mean age, 24.4 ± 3.1 years; mean ± SD) with self-reported awake/sleep bruxism were recruited and divided into a BF (n = 10) and a control (CO) group (n = 7). All subjects underwent four EMG recording sessions during both daytime and sleep over 3 weeks. During the daytime, in week 2, the BF group received feedback alert signals when excessive EMG activity with certain burst duration was detected while the subjects performed regular daily activities. The CO group underwent EMG recording sessions without receiving any alerts of parafunctional activity. The number of phasic burst events during sleep was compared between the BF and CO groups. RESULTS: While the number of phasic EMG events was not significantly different between the BF and CO groups at baseline, significantly smaller phasic events were observed in the BF compared to the CO group at the follow-up session (week 3) (P = .006, Tukey's HSD). Since daytime BF training is aimed at raising awareness of awake bruxism, it does not interrupt the sleep sequence or involve associated side effects. CONCLUSION: The present results suggest that EMG BF targeting for tonic EMG events during the daytime can be an effective method to regulate phasic EMG events during sleep.
