RESUMO
BACKGROUND: Bruxism, a common oral parafunctional behavior characterized by the grinding or clenching of teeth, is a multifactorial condition with potentially detrimental effects on oral health and overall well-being. In recent years, there has been growing interest in understanding the relationship between bruxism and alcohol abuse, as both are prevalent issues that may share underlying factors and exacerbate each other. This systematic review, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, aims to evaluate the frequency of bruxism among individuals with alcohol abuse. METHODS: A comprehensive search of electronic databases, including PubMed, Lilacs, Scopus and Web of Science, will be conducted to identify relevant studies published up to the knowledge cutoff date in January 2023. The search strategy will include keywords related to bruxism, alcohol abuse, and their synonyms. Inclusion criteria will encompass original research studies, such as observational, cross-sectional, cohort, and case-control studies, as well as clinical trials, that examine the relationship between bruxism and alcohol abuse. Two independent reviewers will perform the study selection, data extraction, and quality assessment, with discrepancies resolved by consensus. RESULTS: The systematic review will present a summary of the identified studies, including the study design, characteristics of the study populations, and key findings related to the association between bruxism and alcohol abuse. The potential mechanisms underlying this relationship will also be explored. Subgroup analyses and the quality of evidence will be assessed. Finally, the implications of this association for clinical practice and further research will be discussed. CONCLUSIONS: This systematic review will contribute to a better understanding of the interplay between bruxism and alcohol abuse, shedding light on potential risk factors, mechanisms, and clinical implications. The findings may have significant implications for the prevention, management, and treatment of bruxism, particularly in individuals with a history of alcohol abuse.

OBJECTIVE: To evaluate the self-reported SB prevalence and explore associated risk factors in puerperal women who had given birth in Rio Grande, Southern Brazil. METHODS: A single, standardized questionnaire was given within the 48 h postpartum period. Self-reported SB was the main outcome investigated. Chi-square test was used to compare proportions, and Poisson regression with robust variance adjustment was used in the multivariate analysis. RESULTS: A total of 2225 women were included. Only 79 (3.6%) of these reported clenching or grinding their teeth during sleep. Adjusted analysis showed that the higher education level of the mothers (PR = 3.07; 95% CI 1.49-6.28; P = 0.006); living with three or more persons in the household (PR = 0.54; 95% CI 0.34-0.84; P = 0.007); medication intake during pregnancy (PR = 1.68; 95% CI 1.09-2.58; P = 0.017); smoking (PR = 1.93; 1.16-3.23; P = 0.024), or ever smoked (PR = 1.82; 95% CI 0.85-3.90; P = 0.024); severe anxiety (PR = 1.36; 95% CI 0.61-3.02; P = 0.005); and headache upon waking (PR = 4.19; 95% CI 1.95-9.00; P < 0.001) were significantly associated with self-reported SB. CONCLUSION FOR PRACTICE: Our data pointed towards new factors in a specific group of women that may be relevant for preventing sleep-related behaviors in the pregnancy-puerperal cycle. The higher levels of education, medication intake, smoking or even smoked, severe anxiety, the higher the probability of puerperal woman to self-report SB. The nighttime tooth clenching strongly increased headache upon waking.

Bruxism may lead to changes or damage to the oral and perioral tissues. Bruxism may occur during sleep or when awake. Many patients will not require active management; however, for some, intervention is required. Control of bruxism may be difficult, if not impossible, but the need exists for preservation of the dentition and quality of life. A prediction of risk to the tissues for the planning of interventions is difficult and relies upon evidence of past damage and assessment of future risks. Treatment options may need to be imaginative and rescuable. This series of papers will review the aetiology of bruxism, its impacts and treatment strategies for persistent bruxers who are at risk of, or suffering, tissue damage.

(1) Background: Bruxism, a condition characterized by grinding and involuntary clenching of the teeth, is a risk factor for the development of masticatory dysfunction. It can occur together with sleep disturbances and may be associated with abnormal body movements, breathing difficulties, increased muscle activity, and heart rate disturbances. This disorder is becoming an important dental concern in children. (2) Methods: A literature review was carried out based on a search in PubMed and Google Scholar databases for articles on bruxism in children, published between 2014 and 2021. The etiology, diagnosis, and treatment of bruxism in children were of particular interest in the study. (3) Results: A total of 40 articles were included in the review. The analyzed studies indicated that the prevalence rates of bruxism in children vary widely from 13% to 49%. The etiology of bruxism is complex and incomprehensible, and the main diagnostic criteria for this condition in children are subjective observation, clinical history, and clinical examination. The recommended therapy for sleep bruxism in children is physiotherapy and psychotherapy. (4) Conclusions: Dentists and primary care physicians should correctly diagnose bruxism in children, educate parents, prevent potential consequences for oral health, and identify possible comorbidities. Appropriate clinical guidelines for the treatment and prophylaxis of bruxism in children should also be developed.

Bruxism has become more and more debatable and pressing issue all over the world last years. the etiology of bruxism has been changing diverse definitions, over the years, however recently it is defined as a repetitive jaw-muscle activity characterized by clenching or grinding of the teeth and by bracing or thrusting of the mandible. This literature review discusses the possible risk factors of bruxism in children and adolescence, among which behavioral abnormalities and sleep disturbances predominates. Moreover, it reviews pathological impact of bruxism on general health and quality of life. The literature review has been carried out using the "ScienceDirect", "Scopus" and "PubMed" databases in order to define relevant scientific works - published in English, during the last 5 years. 31 most relevant articles were chosen. Bruxism is a psychophysiological disorder that can take place during the day and/ or night, in a form of clenching and grinding. It can cause health problems such as tooth sensitivities, headaches, facial myalgia, ear ache, tightness/stiffness of the shoulders, limitation of mouth opening, sleep disruption, sleep disruption of bed partner due to noise, excess tooth mobility, inflamed & receding gums, Temporomandibular Joint Disorder, tooth wear and breakage and tongue's deformation. Considering the potential negative consequences of bruxism on dental and oral health, various clinical methods have been devised to assess it over the years. As the etiology is multifactorial, there is no exact treatment to prevent bruxism. Counselling and behavioral strategies, splint therapy, medications, and contingent electrical stimulation can be used as different ways reducing the effects of bruxism.

The aim of this study was to verify the oral habits, symptoms, and characteristics of some children aged 8 to 10 years that could be associated with possible sleep bruxism. A cross-sectional study was performed. Questionnaires were sent to parents to obtain information on sex, age, school shift, sleep quality, parents' perception of children's behavior, and children's oral habits (nail biting, object biting, and lip biting), and symptoms such as headache or earache. In addition, parents reported the frequency of sleep bruxism (no day to 7 days a week). Descriptive analysis and multinomial logistic regression were performed and the level of significance was set at 5%. A total of 1,554 parents of children aged 8 to 10 years participated in this study. Possible sleep bruxism was reported as mild for 65.7%, moderate for 25.3%, and severe for 9% of the children. In the adjusted multinomial logistic regression, boys were 79% more likely to have sleep bruxism (OR: 1.79; 95%CI 1.23-2.60) and were 2.06 more times at risk of being in the habit of lip biting (OR: 2.06; 95%CI 1.26-3.37). Children with possible severe sleep bruxism were 61% more likely to develop object biting (OR: 1.61; 95%CI 1.09-2.39), 52% more likely to have headaches (OR: 1.52; 95%CI 1.01-2.28), and 3.29 more times at risk of poor sleep quality (OR: 3.29; 95%CI 2.25-4.82). Based on the report, boys with lip and object biting habits, headaches, and poor sleep quality presented a higher chance of possible severe sleep bruxism.

OBJECTIVE: Sleep bruxism, a major sleep disorder that causes serious harm to oral health, is considered a multifactorial disease. Sleep bruxism can be induced by smoking, which also adversely affects sleep quality. The objective of present study was to clarify the associations between sleep bruxism, sleep quality, and exposure to secondhand smoke (SHS). METHODS: To assess the prevalence of sleep bruxism, sleep quality, and SHS exposure, we conducted oral examinations and self-report questionnaires on university students in Japan. Sleep bruxism and quality were screened using the Japanese version of the Pittsburgh Sleep Quality Index (PSQI) and the third edition of the International Classification of Sleep Disorders (ICSD-3). The inclusion criteria were adults aged between 18 and 19 years, non-smokers and non-alcohol drinkers. The exclusion criteria was failing to complete the questionnaire in full. RESULTS: We analyzed a total of 1781 Japanese young adults. Young adult females who had been exposed to SHS had worse sleep quality (p = 0.019) than those who had not. Young adult female with worse sleep quality showed a higher prevalence of sleep bruxism (p = 0.034) than those with better sleep quality. Using structural equation modeling, direct associations were identified between SHS exposure and poor sleep quality (standardized coefficients, 0.153; p = 0.008) and between sleep bruxism and poor sleep quality (standardized coefficients, 0.187; p = 0.022) in young adult females. However, no association was found among young adult males. CONCLUSION: SHS exposure is indirectly associated with sleep bruxism through poor sleep quality in Japanese young adult females.

Sleep bruxism (SB) is a common phenomenon defined as a masticatory muscle activity during sleep. Untreated severe SB can have significant dental and orofacial consequences. SB has often been linked with stress and maladaptive coping strategies. Therefore, in this study, a potential correlation between SB, perceived stress and coping strategies was evaluated. A total of 60 adults were enrolled into this study. Participants underwent a detailed intra- and extraoral exam focused on detecting bruxism symptoms. Additionally, the overnight Bruxism Index was recorded using the Bruxoff device. A total of 35 participants with symptoms of bruxism were assigned to the study group, whereas 25 asymptomatic participants were assigned to the control group. The Perceived Stress Scale (PSS-10) was used for stress assessment and Brief-COPE for coping strategies. Results showed that the higher the PSS-10 score, the higher the Bruxism Index was in the study group. Positive coping strategies were chosen most frequently in the control group, while maladaptive ones were chosen in the study group. It can be concluded that there is a relationship between perceived stress and sleep bruxism. Moreover, the type of coping strategies used by participants may have an impact on sleep bruxism, but the relationship should be further investigated.

OBJECTIVE: To evaluate the prevalence of sleep bruxism, as well as its principal signs and symptoms, in the city of Rio Grande. Evaluate the association of sleep bruxism with gender, age, education and psychological stress. METHOD: The study was cross-sectional type. A representative sample of the population (1280 people residing in the urban area of the city aged greater than or equal to 18 years old) were interviewed. The evaluation of sleep bruxism was by mean of questionnaire based on diagnostic criteria of the International Classification of Sleep Disorders. RESULTS: The prevalence of sleep bruxism found in the population was 8,1% (confidence interval of 95% - 95%CI - 6,6 - 9,5). Among the signs and symptoms of dysfunction used for the diagnosis of sleep bruxism, tooth wear (70,3%) and pain in masticatory muscles (44,5%) were the most frequently reported by people who report teeth grinding during sleep. There was no significant difference in the prevalence of sleep bruxism between sexes. People older than 40 had a higher prevalence of sleep bruxism. The dysfunction was associated with a higher level of education (prevalence ratio - PR = 1.92; 95%CI 1,35 - 2,72) and psychological stress (PR 1,76; 95%CI 1,11 - 2,81). CONCLUSION: There was a significant prevalence of sleep bruxism in the general population, causing various damages to the Stomatognathic system. The psychological stress is a risk factor for this dysfunction.

Stimulants-related bruxism has been previously reported; both diurnal and nocturnal. Here, authors report on a case of methylphenidate (MPH)-treated attention-deficit/hyperactivity disorder that developed nocturnal bruxism and failed multiple pharmacologic trials. Add-on clonidine has successfully helped with bruxisms while augmenting MPH response. This was achieved with great tolerability. This remains a viable option to deploy in such unusual clinical scenarios.

Prader-Willi syndrome (PWS) is a complex disorder that affects multiple systems and may cause craniofacial and dentofacial abnormalities. However, there is still a lack of evidence in the literature regarding the progress of orthodontic treatment in patients with PWS. This case report describes the successful orthodontic treatment of a patient with PWS. A girl, 9 years 0 months of age, who had been diagnosed with PWS had protruding maxillary incisors and a convex profile. Her malocclusion was due to the posteriorly positioned mandible. Screening tests for sleep apnea syndrome showed that she had sleep-disordered breathing, including obstructive sleep apnea and bruxism. We also observed an excessive overjet of 10.0 mm, a deep overbite of 6.8 mm, and the congenital absence of the mandibular second premolars. The patient was diagnosed with an Angle Class II malocclusion and a skeletal Class II jaw-base relationship with a deep overbite. Functional appliance therapy with mandibular advancement, which can enlarge the upper airway and increase the upper airspace, was performed to prevent further deterioration of the patient's obstructive sleep apnea. An acceptable occlusion with a proper facial profile and functional excursion were achieved without interference after comprehensive 2-stage treatment that incorporated orthodontic therapy for the patient's excessive overjet and deep overbite. The resulting occlusion was stable, and the occlusal force and the contact area gradually increased over a 2-year retention period. These results suggest that orthodontic treatment offers the opportunity to greatly improve the health and quality of life of people with PWS.

Bruxism is characterised by clenching or grinding of the teeth due to contraction of the masseter, temporalis and other jaw muscles. Bruxism may lead to masticatory muscle hypertrophy, tooth surface loss, fracture of restorations or teeth, hypersensitive or painful teeth and loss of periodontal support. Sleep bruxism has previously been viewed as a dysfunctional movement or pathological condition, whereas it is now accepted as a centrally controlled condition with various systemic risk factors. It has been postulated that sleep bruxism may have a protective role during sleep, for example in relation to airway maintenance or in stimulating saliva flow. A diagnosis of sleep bruxism may be made via patient report and clinical interview, clinical examination, intraoral appliances or recording of muscle activity. Bruxism in itself does not require treatment: management is only indicated where problems arise as a result of bruxism. Oral appliances primarily aim to protect the dentition from damage caused by clenching/grinding, although they may reduce muscle activity. Irreversible occlusal adjustments have no basis in evidence in the management of bruxism. Behavioural strategies include biofeedback, relaxation and improvement of sleep hygiene. Administration of botulinum toxin (Botox) to the masticatory muscles appears to reduce the frequency of bruxism, but concerns have been raised regarding possible adverse effects. Dentists should be aware of the potential aetiology, pathophysiology and management strategies of sleep bruxism.

The aim of the present study was to evaluate factors associated with sleep bruxism in five-year-old preschool children. A preschool-based cross-sectional study was conducted with 761 pairs of children and their parents/caregivers. Sleep bruxism was diagnosed using a questionnaire administered to the parents/caregivers, who also answered questionnaires addressing sociodemographic data and parent's/caregiver's sense of coherence. Clinical oral evaluations of the children to determine dental caries, traumatic dental injuries, malocclusion and tooth wear were performed by two researchers who had undergone a training exercise (interexaminer Kappa: 0.70 to 0.91; intraexaminer Kappa: 0.81 to 1.00). Descriptive analysis and logistic regression for complex samples were carried out (α = 5%). The prevalence of sleep bruxism among the preschool children was 26.9%. The multivariate analysis revealed that bruxism was associated with poor sleep quality (OR = 2.93; 95 CI: 1.52-5.65) and tooth wear (OR = 2.34; 95%CI: 1.39-3.96). In the present study, sleep bruxism among preschool children was associated with tooth wear and poor sleep quality of the child. In contrast, psychosocial aspects (sense of coherence) were not associated with sleep bruxism.

Sleep bruxism (SB) and psychological stress are commonly considered as contributing factors in the aetiology of temporomandibular disorder (TMD) pain. However, the lack of longitudinal studies and fluctuating nature of SB, psychological stress and TMD pain have led to contradictory results regarding the association between the possible aetiological factors and TMD pain. In the present study we investigated the contribution of SB and psychological stress to TMD pain in a longitudinal study of 2 clinical TMD pain cases during a 6-week study protocol. Two female volunteers with clinically diagnosed myalgia based on the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) participated in the study. Questionnaires were used to record jaw-muscle pain and psychological stress experience, and an ambulatory polysomnography technique was used to record SB intensity. Visual analysis of the data revealed that the intensity of TMD pain was not hardwired, neither with psychological stress experience nor with increased SB activity. Within the limitations of single-patient clinical cases design, our study suggested that the presence of TMD pain cannot be explained by a simple linear model which takes psychological stress or SB into account. It also seems that psychological stress was a more important predictor factor for TMD pain than SB.

OBJECTIVE: This systematic review was performed to determine the risk factors related to bruxism in children. DESIGN: This systematic review was conducted with reporting in agreement to the PRISMA statement and according to guidelines from the Cochrane Handbook for Systematic Reviews of Interventions. We conducted a systematic search of seven online databases, with the last search updated on 1st October 2016. The seven databases were Pubmed, Embase, Cochrane Library database, Web of Science, CNKI, CBM, and WF. The included trial type were RCT, cohort studies, and case-control studies, and bruxism symptoms were assessed by questionnaires and examinations. Eighteen out of the 5637 initially identified studies met the inclusion and exclusion criteria. RESULTS: gender, age, gene, mixed position, anxiety, the nervous, secondhand smoke, high psychological reactions, responsibility, move a lot during sleep, sleeps with mouth open, snores loudly, restless sleep, sleep hours, sleep with light on, noise in room, headache, biting, cheeks tonus, perioral musculature participation, conduct problems, peer problems, emotional symptoms, mental health problems, birth weight, occupation of family head, maternal marital status, hyperactivity, family income seemed to have statistical significance from the present systematic review and meta-analysis. CONCLUSIONS: The risk factors related to bruxism were as follows: Male, gene, mixed position, moves a lot, anxiety, the nervous, psychological reactions, responsibility, secondhand smoke, snore loudly, restless sleep, sleep with light on, noise in room, "sleep hours, ≤8h", headache, objects biting, conduct problems, peer problems, emotional symptoms and mental health problems.

Abstract The aim of the present study was to evaluate factors associated with sleep bruxism in five-year-old preschool children. A preschool-based cross-sectional study was conducted with 761 pairs of children and their parents/caregivers. Sleep bruxism was diagnosed using a questionnaire administered to the parents/caregivers, who also answered questionnaires addressing sociodemographic data and parent's/caregiver's sense of coherence. Clinical oral evaluations of the children to determine dental caries, traumatic dental injuries, malocclusion and tooth wear were performed by two researchers who had undergone a training exercise (interexaminer Kappa: 0.70 to 0.91; intraexaminer Kappa: 0.81 to 1.00). Descriptive analysis and logistic regression for complex samples were carried out (α = 5%). The prevalence of sleep bruxism among the preschool children was 26.9%. The multivariate analysis revealed that bruxism was associated with poor sleep quality (OR = 2.93; 95 CI: 1.52-5.65) and tooth wear (OR = 2.34; 95%CI: 1.39-3.96). In the present study, sleep bruxism among preschool children was associated with tooth wear and poor sleep quality of the child. In contrast, psychosocial aspects (sense of coherence) were not associated with sleep bruxism.

Los trastornos temporomandibulares (TTM) corresponden a un grupo de condiciones musculoesqueletales y neruromusculares que involucran las articulaciones temporomandibulares (ATM), los músculos masticatorios y todos los tejidos asociados. La etiología de los TTM es considerada multifactorial, siendo el bruxismo de sueño (BS) uno de muchos factores asociados con TTM dolorosos. Tanto los TTM como el BS se presentan en adultos y niños y actualmente es sabido que la etiopatogenia de ambos no difiere de acuerdo a la edad. Las ATM son articulaciones sinoviales que pueden verse afectadas por diversos TTM o por condiciones sistémicas como la artritis idiopática juvenil (AIJ). La ATM está involucrada en un 40% de los pacientes con AIJ, siendo subestimada debido a que clínica-mente se manifiesta con poco dolor. En el presente artículo se revisarán los conceptos de TTM y BS en niños, así como también la manifestación de la AIJ en el territorio orofacial, entregando una aproximación de su etiopatogenia, identificación y manejo.
Temporomandibular disorders (TMD) encompass a group of musculoskeletal and neuromuscular conditions that involve the temporomandibular joints (TMJ), the masticatory muscles, and all associated tissues. TMD's etiology is considered to be mul-tifactorial, were sleep bruxism (SB) is one of many causes of painful TMD. TMD and SB can present in adults and children and the etiology does not differ regarding age.TMJ are synovial joints that can be affected by many TMD as well as systemic conditions such as juvenile idiopathic arthritis (JIA). TMJ are involved in 40% of patients with JIA, which is usually underestimated because of its painless presentation.This article will review the concepts of TMD and SB in children, as well as JIA presentation in the orofacial region.

Although well studied since the 50's, bruxism remains a largely unknown pathology. Its origin is complex, mixing psychological as well as neurological, odontological and hypnic aspects. However, the few analyzes performed on this topic have allowed to set convincing etiopathological hypotheses, including central dysregulation of the dopaminergic system as well as of the neuro-masticatory system. To avoid harmful consequences as headaches, temporomandibular disorders and premature dental scuffs / fractures, it is mandatory to diagnose bruxism as early as possible. For this purpose, and in addition to anamnestic and clinical data, the practitioner can confirm diagnosis with polysomnography, including electromyographic study of masticatory muscles and audiovisual recording. Some orthodontic, pharmacological and psychological solutions have already proved efficient. Nevertheless, a better knowledge of causative neurobiological mechanisms would allow to foresee etiology-based treatments.
Le bruxisme reste, à l'heure actuelle, une pathologie relativement mal connue, bien que déjà étudiée depuis le début des années 50. Son origine est complexe, impliquant des composantes psychologiques, neurologiques, odontologiques et hypniques. Les quelques analyses réalisées à ce sujet ont, toutefois, permis de mettre en avant certaines hypothèses étiopathogéniques convaincantes, notamment un dérèglement central du système dopaminergique et du système neuromasticateur. Un diagnostic rapide de l'affection permettra de réduire ses complications (céphalées, désordres temporomandibulaires, abrasion et fractures dentaires prématurées). Au-delà de l'anamnèse et de l'examen clinique, le praticien pourra confirmer le diagnostic par polysomnographie, incluant une étude électromyographique des muscles masticateurs et un enregistrement audiovisuel. Certaines solutions orthodontiques, pharmacologiques et psychologiques ont déjà prouvé leur efficacité. Néanmoins, une meilleure connaissance des mécanismes neurobiologiques incriminés permettrait d'envisager un traitement étiologique.
