RESUMO

BACKGROUND: Bruxism is excessive teeth grinding or jaw clenching. Several symptoms are commonly associated with bruxism, including hypersensitive teeth, aching jaw muscles, headaches, tooth wear, and damage to dental restorations. There are two types of bruxism, awake bruxism and sleep bruxism. Awake bruxism is generally treated by dentists and maxilla-facial surgeons through several treatment modalities such as, counselling about triggers, relaxation, occlusal splints and botulinum toxin type A injections. METHODS: We will present the case of a 21-year-old woman presenting mood swings with a high level of anxiety and concentration difficulties since childhood. She also complained of awake bruxism. Intelligence was evaluated using The Wechsler Adult Intelligence Scale - Fourth Edition (WAIS-IV). Attention-deficit hyperactivity disorder (ADHD) was investigated through a neuropsychology test. RESULTS: Intelligence evaluation showed normal intellectual function. Neuropsychology test showed a profile corresponding to ADHD. Bupropion XR 300 mg was initiated for ADHD. Pregabalin was prescribed for general anxiety syndrome. The patient reported a complete disappearance of awake bruxism at a daily dose of 375 mg, with no occlusal appliances. Following the improvement of the anxiety symptoms, the attempt to reduce the dose twice leading to the recurrence of bruxism. CONCLUSIONS: A 21 years old female treated with 375 mg daily doses of pregabalin for generalized anxiety disorder experienced a significant reduction of daytime bruxism. More studies are needed to determine whether pregabalin has a long term effect against awake bruxism.

RESUMO

BACKGROUND: The aim of this study was to evaluate the association of bruxism and treatment regimens among remitted bipolar patients. SUBJECTS AND METHODS: The total case group included 222 adult patients with BD. Diagnosis of bruxism was based upon the on 'self-reports' plus the outcome from the clinical examinations. RESULTS: The sample consisted of 112 (50.5%) bipolar patients with bruxism and 110 (49.5%) without bruxism. Remitted bipolar patients who were on mood stabilizer plus atypical antipsychotic treatment had lower bruxism rates than patients on other than bipolar patients on mood stabilizer treatment regimen (p=0.04) and bipolar patients on polypharmacy (p=0.01). CONCLUSION: Our findings have supported the existence of psychotropic drug-bruxism relation and atypical antipsychotic related therapeutic effect among bipolar patients.

RESUMO

Objective: Bruxism is a condition defined as a masticatory muscle activity with an unexplored genetic background. The aim of this study was to evaluate the association between genetic polymorphisms in ACTN3 and bruxism. Study design: A total of 151 biological-unrelated children, aged 7-12 years were included in a case control ratio of 1:1.5. The data collection was performed during interview and clinical examination. Saliva samples were collected from all children and 3 genetic polymorphisms in the ACTN3 (rs678397, rs1671064 and rs1815739) were selected for genotyping using real time PCR. Pearson chisquare calculation was used to assess Hardy-Weinberg equilibrium and to evaluate the association between genotypes and alleles frequencies for each genetic polymorphism in the co-dominant and recessive models. An alpha of 5% was used. Results: The genetic polymorphisms rs678397, rs1671064 and rs1815739 were associated with bruxism in the co-dominate model and in the recessive model (p<0.05). Allele distribution was also associated with bruxism for the polymorphisms rs678397 and rs1671064 (p<0.05). Conclusion: The genetic polymorphisms rs678397, rs1671064 and rs1815739 in ACTN3 are associated with bruxism and can contribute to the etiology of this condition in children.

RESUMO

INTRODUCTION: This study aimed to evaluate whether the presence of awake bruxism was associated with temporomandibular dysfunction symptoms, pain threshold at pressure, pain vigilance, oral health-related quality of life (OHRQoL), and anxiety and depression symptoms in patients undergoing orthodontic treatment. METHODOLOGY: This observational study followed patients who had started receiving orthodontic treatment for six months. The following variables were measured three times (at baseline, one month, and six months): pressure pain threshold (PPT) in the right and left masseter, anterior temporalis, and temporomandibular joint (TMJ), and right forearm; pain vigilance and awareness questionnaire; and shortened form of the oral health impact profile (OHIP-14). Anxiety and depression symptoms were measured using the Beck anxiety inventory and the Beck depression inventory, respectively. The patients were divided into two main groups according to the presence (n=56) and absence (n=58) of possible awake bruxism. The multi-way analysis of variance (ANOVA) was applied on the date (p=0.050). RESULTS: TMJ and/or muscle pain were not observed in both groups. Time, sex, age group, and awake bruxism did not affect the PPT in the masticatory muscles and pain vigilance (p>0.050). However, the primary effect of awake bruxism was observed when anxiety (ANOVA: F=8.61, p=0.004) and depression (ANOVA: F=6.48, p=0.012) levels were higher and the OHRQoL was lower (ANOVA: F=8.61, p=0.004). CONCLUSION: The patients with self-reported awake bruxism undergoing an orthodontic treatment did not develop TMJ/masticatory muscle pain. The self-reported awake bruxism is associated with higher anxiety and depression levels and a poorer OHRQoL in patients during the orthodontic treatment.

RESUMO

Los signos de desgaste y rechinamiento de los dientes están asociados con el bruxismo y se observan comúnmente en los consultorios dentales. En este reporte, las autoras describen un caso de bruxismo probablemente inducido por el medicamento anticonvulsivo Valpromed®, que fue tratado con éxito mediante una férula dental. El paciente llegó a la clínica declarando que deseaba mejorar su estética. En el examen clínico, se observó un desgaste moderado de las superficies oclusales de los molares asociado con antecedentes de rechinamiento nocturno, característico del bruxismo del sueño. Hace aproximadamente 5 meses, el paciente comenzó la terapia con Valpromed® por orden del neurólogo, debido a episodios de migraña. El medicamento se prescribió para evitar el riesgo de convulsiones ya que el paciente había sufrido de neurocisticercosis durante la infancia. Según los consejos del especialista en rehabilitación oral y la literatura revisada, las autoras concluyeron que el bruxismo podía atribuirse a la terapia con el medicamento anticonvulsivo. Para el tratamiento, se escogió una técnica mínimamente invasiva. Aunque el paciente todavía está en controles, la férula dental parece ser un enfoque prometedor para el tratamiento de esta afección.

Signs of tooth wear and grinding are associated with bruxism, which is commonly observed in dental offices. Here, the authors describe a case of bruxism probably induced by the anti-seizure drug Valpromed®, that was successfully treated with a dental splint. A man was attended in the dental clinic for improvement of dental aesthetics. On clinical examination moderate overwear of the occlusal surfaces of molars was observed associated with a history of nightly grinding, characteristic of sleep bruxism. Approximately 5 months previously, the patient had started therapy with Valpromed® due to episodes of migraine. The drug had been prescribed by a neurologist to prevent convulsions since the patient had had neurocysticercosis during childhood. Based on the advice of an oral rehabilitation specialist and the literature reviewed, it was concluded that the presence of bruxism in this patient may be attributed to the therapy with the anti-seizure medication. Although the patient is still under controls, the dental splint seems to be a promising approach for the treatment of this condition. The patient was treated with a minimally invasive dental splint and is monitored periodically, showing good results. (AU)

RESUMO

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.

RESUMO

Background: There are important criteria in the diagnosis of temporomandibular disorders (TMDs). These become significant if supported by magnetic resonance imaging (MRI). Otherwise, these findings alone may not be sufficient to diagnose TMD. Aim: This study compared the relationship between clinical findings indicated by patient and physician and MRI results in the diagnosis of TMD. Materials and Methods: Clinical examinations were performed in patients suspected of TMD for pain, difficulty in mouth opening, masticatory muscle tenderness, deviation (during mouth opening), normal mouth opening, and presence of bruxism. The MRI findings of the patients were compared with the clinical examinations. Results: MRI and clinical examination data of 136 patients were examined. The results showed significant correlations between deviation, normal mouth opening, and MRI results of TMD (P < 0.05). No correlation was found between age groups and clinical findings of TMD. TMJ was determined in normal limits in 61% of MRI results. Conclusions: Except for deviation and normal mouth opening, complaints and clinical findings determined by the clinicians do not support TMD. This may be due to the subjective nature of the clinical findings, and MRI results are needed for precise results.

RESUMO

INTRODUCTION: Bruxism is often indicated as a risk factor for the occurrence of temporomandibular disorders (TMD). Despite the frequent co-occurrence of bruxism and TMD, the exact relationship between these phenomena has not been thoroughly explained, and their causal relationship is still considered controversial. AIM: The aim of this study was to evaluate the distribution of TMD among sleep bruxers and non-bruxers. MATERIALS AND METHODS: The participants of this study were 77 patients of the Clinic of Prosthetic Dentistry operating at the Department of Prosthetic Dentistry, Wroclaw Medical University who had been diagnosed with TMD and probable sleep bruxism. Patients underwent video-polysomnography to assess the intensity of sleep bruxism using the Bruxism Episode Index (BEI). RESULTS: The following TMD diagnoses were made: local myalgia, temporal tendonitis, myofascial pain, myofascial pain with referral, hypertrophy, osteoarthrosis, disc displacement with reduction, disc displacement without reduction with limited opening, subluxation, adhesions/adherence, arthralgia, headache attributed to TMD and oromandibular dystonia. None of these occurred statistically significantly more often in the studied group (bruxers; BEI ≥ 2) than in the control group (non-bruxers; BEI < 2); (P > .05 for all comparisons). CONCLUSION: The distribution of TMD among sleep bruxers and non-bruxers is similar. Therefore, the prevalence of sleep bruxism seems not to be a certain risk factor for TMD occurrence.

RESUMO

Objectives To evaluate the clinical-effectiveness of oral splints for patients with TMD or bruxism for the primary outcomes: pain (TMD) and tooth wear (bruxism).Data sources Four databases including MEDLINE and EMBASE were searched from inception until 1 October 2018.Data selection and extraction Randomised controlled trials comparing all types of splints versus no/minimal treatment for patients with TMD or bruxism were eligible. Standard Cochrane review methods were used. Standardised mean differences (SMD) were pooled for the primary outcome of pain, using random effects models in TMD patients.Data synthesis Thirty-seven trials were included and the evidence identified was of very low certainty using GRADE assessments. When all subtypes of TMD were pooled into one global TMD group, there was no evidence that splints reduced pain: SMD (up to 3 months) -0.18 (95% CI -0.42 to 0.06); 13 trials, 1,076 participants. There was no evidence that any other outcomes improved when using splints. There was no evidence of adverse events associated with splints, but reporting was poor regarding this outcome. No trials measured tooth wear in patients with bruxism. There was a large variation in diagnostic criteria, splint types and outcome measures used and reported. Sensitivity analyses based on these factors did not indicate a reduction in pain.Conclusions The very low-certainty evidence identified did not demonstrate that splints reduced pain in TMD as a group of conditions. There is insufficient evidence to determine whether splints reduce tooth wear in patients with bruxism.

RESUMO

Aims: Systemic Lupus Erythematosus (SLE) is a connective tissue disease characterized by a wide range of pleomorphic pictures, including mucocutaneous, renal, musculoskeletal and neurological symptoms. It involves oral tissues, with hyposalivation, tooth decay, gingivitis, angular cheilitis, ulcers and glossitis. Temporomandibular disorders represent a heterogeneous group of inflammatory or degenerative diseases of the stomatognatic system, with algic and/or dysfunctional clinical features involving temporomandibular joint (TMJ) and related masticatory muscles. The aim of this study was to investigate the prevalence of oral manifestations and temporomandibular disorders (TMD) in SLE patients (Lp) compared with a control group. Methods: Fifty-five patients (9 men and 46 women) with diagnosed Lupus were recruited in the study group. A randomly selected group of 55 patients, matched by sex and age, served as control group. The examination for TMD symptoms and signs was based on the standardized Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) through a questionnaire and clinical examination. Results: Lupus patients complained more frequently (95.8%) of oral and TMJ symptoms (dysgeusia, stomatodynia, masticatory muscle pain during function, neck and shoulder muscles pain and presence of tinnitus) but only xerostomia (χ2=4,1548 p=0,0415), temple headache (χ2=4,4542 p=0,035) and the sensation of a stuck jaw (Mid-p-test p=0,043) were significant. About signs, cheilitis (p=0,0284) oral ulcers (χ2=4,0104 p=0,045) and fissured tongue are significantly more frequent in study group. The salivary flow was significantly decreased in the study group respect to the control one (p<0.0001). As regard to the oral kinematics, restricted movements (RM) in protrusion and left lateral movement were significantly different between study group and controls. In particular, 85,2% of Lp showed limited protrusion versus 56,4% of controls (χ2= 10,91 p<0,001); 59,3% of Lp had also a limitation during left lateral movement versus 47,3% of controls (T=2,225 p=0,0282). About bruxism, only the indentations on the lateral edges of the tongue were found in Lp group (72,7%), with a significant difference respect to controls (χ2=7,37 p=0,007). Conclusions: While masticatory muscles have an overlapping behavior in both groups, the findings collected show a more severe TMJ kinematic impairment in Lp than in controls, with protrusion and left lateral movements significantly different. In addition, a remarkable reduction of salivary flow has been detected in Lp compared to controls. In conclusion, this autoimmune disease seems to play a role in oral manifestations and TMJ disorders, causing an increase in orofacial pain and an altered chewing function.

RESUMO

BACKGROUND: Studies have shown co-contraction of jaw and neck muscles in healthy subjects during (sub) maximum voluntary jaw clenching, indicating functional inter-relation between these muscles during awake bruxism. So far, coherence of jaw and neck muscles has not been evaluated during either awake or sleep bruxism. OBJECTIVE: The objective of this study was to evaluate the coherence between jaw and neck muscle activity during sleep bruxism. METHODS: In a cross-sectional observational design, the electromyographic activity of jaw (masseter, temporalis) and neck (sternocleidomastoid, trapezius) muscles in individuals with "definite" sleep bruxism was measured using ambulatory polysomnography (PSG). Coherence for masseter-temporalis, masseter-sternocleidomastoid and masseter-trapezius was measured during phasic and mixed rhythmic masticatory muscle activity episodes using coherence-analysing software. Outcome measures were as follows: presence or absence of significant coherence per episode (in percentages), frequency of peak coherence (FPC) per episode and sleep stage. RESULTS: A total of 632 episodes within 16 PSGs of eight individuals were analysed. Significant coherence was found between the jaw and neck muscles in 84.9% of the episodes. FPCs of masseter-temporalis were significantly positively correlated with those of masseter-sternocleidomastoid or masseter-trapezius (P < .001). Sleep stages did not significantly influence coherence of these muscular couples. CONCLUSION: During sleep bruxism, jaw and neck muscle activation is significantly coherent. Coherence occurs independently of sleep stage. These results support the hypothesis of bruxism being a centrally regulated phenomenon.

RESUMO

The aim of the present paper was to give an overview of the general project and to present the macrostructure of a comprehensive multidimensional toolkit for the assessment of bruxism, viz. a bruxism evaluation system. This is a necessary intermediate step that will be detailed in a successive extended publication and will ultimately lead to the definition of a Standardized Tool for the Assessment of Bruxism (STAB) as the final product. Two invitation-only workshops were held during the 2018 and 2019 General Session & Exhibition of the International Association for Dental Research (IADR) meetings. Participants of the IADR closed meetings were split into two groups, to put the basis for a multidimensional evaluation system composed of two main axes: an evaluation Axis A with three assessment domains (ie subject-based, clinically based and instrumentally based assessment) and an aetiological/risk factors Axis B assessing different groups of factors and conditions (ie psychosocial assessment; concurrent sleep and non-sleep conditions; drug and substance use or abuse; and additional factors). The work of the two groups that led to the identification of different domains for assessment is summarised in this manuscript, along with a road map for future researches. Such an approach will allow clinicians and researchers to modulate evaluation of bruxism patients with a comprehensive look at the clinical impact of the different bruxism activities and aetiologies. The ultimate goal of this multidimensional system is to facilitate the refinement of decision-making algorithms in the clinical setting.

RESUMO

AIM: The aim of the present study was to evaluate the clinical performance of a glass hybrid restorative compared with a nano-ceramic composite resin in non-carious cervical lesions (NCCLs) of patients with bruxism. MATERIALS AND METHODS: Twenty-five patients with NCCLs and bruxism were enrolled in the present study. Before treatment, the dimensions of the NCCLs (depth, cervico-incisal height, and mesio-distal width) and internal angles were measured. Degree of tooth wear (TWI) and gingival conditions were recorded. A total of 148 NCCLs were randomly restored with a glass hybrid restorative system (GH) (Equia Forte Fil, GC, Tokyo, Japan) or a nano-ceramic composite resin (RBC) (Ceram.X One Universal, Dentsply, DeTrey, Konstanz, Germany). The restorations were evaluated at baseline and after 6, 12, and 24 months according to the modified USPHS criteria. Data were analyzed with Pearson's chi-square, Fisher's exact, Mann-Whitney U, and Cochran's Q tests (P < 0.05). RESULTS: At the 24-month recall, 126 restorations in 22 patients were evaluated. The recall rate was 88.0%. No significant difference was found between the materials for retention (P = 0.285), and no relationships were found between internal angle, depth, cervico-incisal height, or mesio-distal width and retention of the restorations (P > 0.05). A significant difference was observed between the materials for marginal adaptation (P = 0.002), but no relationships were found among depth, cervico-incisal height, and mesio-distal width and marginal adaptation (P > 0.05). RBC showed better results for marginal adaptation. Between marginal adaptation, TWI, and the gingival index, correlations were significant (P < 0.001, P = 0.002). A significant change was found in marginal discoloration in GH and RBC over time (P = 0.039 and P = 0.004, respectively). Neither secondary caries nor tooth sensitivity was observed on any of the restorations at any evaluation. CONCLUSION: Although nano-ceramic RBC showed better marginal adaptation than GH, both tested restoratives showed clinically acceptable performance for the restoration of NCCLs of patients with bruxism after 24 months of clinical service. TRIAL REGISTRATION: This study is registered on http://clinicaltrials.gov under protocol record KA-16020, Clinical Performance of a Glass Hybrid Restorative in NCCL's of Patients With Bruxism.

RESUMO

As yet, there are still no evidence-based clinical diagnostic and management guidelines for ambulatory single-channel EMG devices, like the BUTLER® GrindCare® (GrindCare), that are used in patients with sleep bruxism. Therefore, a consensus meeting was organised with GrindCare developers, researchers, and academic and non-academic clinicians experienced with the use of ambulatory EMG devices. The aim of the meeting was to discuss and develop recommendations for clinical guidelines for GrindCare usage, based on the existing clinical and research experience of the consensus meeting's participants. As an important outcome of the consensus meeting, clinical guidelines were proposed in which an initial 2-week baseline phase with the device in its inactive (non-stimulus) mode for habituation and assessment of the number of jaw-muscle activities is followed by a 4-week active phase with contingent electrical stimuli suppressing the jaw-muscle activities. As to avoid the commonly reported reduction in sensitivity to the stimuli, a 2-week inactive phase is subsequently installed, followed by a repetition of active and inactive phases until a lasting reduction in the number of jaw-muscle activities and/or associated complaints has been achieved. This proposal has the characteristics of a single-patient clinical trial. From a research point of view, adoption of this approach by large numbers of GrindCare users creates a great opportunity to recruit relatively large numbers of study participants that follow the same protocol.
