The relevance is associated with an increase in the prevalence of bruxism in patients of different age groups. The article discusses etiological factors, clinical manifestations and various diagnostic methods for patients with bruxism. The material of the review is the long-term research of domestic and foreign scientists devoted to the etiology and modern diagnosis of patients with bruxism. Using the Elibrary search engine, 17 articles were selected for the time period from 2003 to 2023. The article uses a descriptive method that allowed us to consider the current state of the problem and outline ways to further solve it. The main content of the study is the analysis of innovative methods for the diagnosis of bruxism, which make it possible to diagnose pathology at the initial stage of the disease and start its treatment in a timely manner. The article emphasizes the need to supplement existing clinical recommendations with innovative methods and diagnostic tools for this pathology. As a result of the analysis of the literature, the authors developed a systematization of all methods of diagnosing bruxism by the subject of the study. The article discusses research aimed at studying the occlusal relationship of the jaws, the diagnosis of a psychopathological condition, the diagnosis of musculoskeletal dysfunction, the diagnosis of neurotransmitter imbalance and the detection of diseases of the musculoskeletal system. The authors concluded that with the advent and introduction of computer technologies into dental practice, innovative methods and tools for diagnosing bruxism were developed, which led to a significant improvement in the quality of dental care provided. Special attention is paid in the article to the importance of the principle of primacy and an interdisciplinary approach in conducting diagnostic studies aimed at identifying bruxism.

Influence of gender and bruxism on the masseter muscle: A population-based magnetic resonance imaging study

This study aimed to (1) examine the cross-sectional area (CSA) of the masseter muscle in relation to bruxism and (2) investigate if there are gender-related differences in the masseter muscle in a population-based magnetic resonance imaging (MRI) study. The study included 720 subjects aged 30-89 years (391 women and 329 men) from the Study of Health in Pomerania, a cross-sectional population-based study assessing the prevalence and incidence of common population-relevant diseases and their risk factors in Northeastern Germany. The participants underwent both a whole-body MRI and a full oral examination. The CSAs of the masseter muscles on both sides were measured from MRI images. The presence or absence of awake and/or sleep grinding and clenching, unilateral chewing, and other parafunctional activities were obtained from the dental interview. Linear and ordinal logistic regression models were used to examine the associations between the CSAs of the masseter, bruxism, and gender. The frequency of bruxism and reports of muscle or joint pain were significantly higher in women. The analysis revealed that a larger masseter CSA was significantly associated with bruxism only in men. The larger CSA was manifested only in the higher frequency bruxers. Bruxism had heterogeneous effects on the masseter muscle between genders. Although a higher prevalence of bruxism was reported by women, the larger CSA of the masseter muscle was significantly higher in bruxing men but not in women. This study emphasizes the need for a gender-specific approach when evaluating the clinical implications of bruxism on the masseter muscle.

Bruxism awareness and self-assessment in dental clinical students: a questionnaire-based study

BackgroundBruxism is a recurrent parafunctional habit characterized by clenching or grinding teeth and/or jaw contractions. It is quite common among dental students and is associated with psychosocial factors such as stress and anxiety. This study aimed to compare bruxism awareness and self-assessment among clinical students with and without bruxism.MethodsThis study included systemically healthy individuals aged 18 to 27 years. Intraoral and extraoral examinations were performed on 128 4th- and 5th-grade dental students with (64) and without bruxism (64), 4th and 5th-grade dental students at Bolu Abant İzzet Baysal University who met the inclusion criteria. The diagnosis of bruxism was based on the 2018 International Consensus and data collected through a validated 33-item questionnaire covering general information and bruxism awareness. The questionnaire included multiple-choice questions on bruxism types, risk factors, symptoms, and impact on periodontal tissues. Statistical analyses were performed via IBM SPSS Statistics, and p < 0.05 was considered statistically significant.ResultsClenching and teeth grinding during sleep, tooth wear, muscle fatigue, pain in the temples, jaw pain, joint trismus, neck pain, and jaw joint pain and clenching while awake were significantly different in bruxism patients (p < 0.05). There was no significant difference between the two groups in terms of bruxism type, symptoms, treatment methods, periodontal tissues, occlusal trauma, diagnostic methods, or the relationship between lifestyle and bruxism (p > 0.05). While 71.9% of those diagnosed with bruxism stated that they had bruxism, 68.8% of those who were not diagnosed stated that they did not have bruxism.ConclusionAlthough dental students are aware of bruxism, their understanding of its multifactorial nature and treatment options needs improvement. Increasing this knowledge could reduce the prevalence of bruxism among dental students and improve patient care.Clinical trial registrationThe clinical trial was retrospectively registered on ClinicalTrials.gov under the identifier NCT06583044, with a registration date of 03/09/2024. https://register.clinicaltrials.gov/prs/beta/studies/S000EUYA00000023/recordSummary.

It's not just adults who gnash their teeth - a comprehensive review of the latest information on bruxism in children

Introduction Bruxism is a parafunction characterized by excessive chewing muscle activity involving grinding or clenching of the teeth. Bruxism has become a significant challenge in the field of pediatric dentistry. Aim of the study The aim of this comprehensive review is to provide an overview of bruxism in children, focusing on etiology, symptoms, diagnosis, and current treatment options. To draw attention to the prevalence of the disorder and to raise awareness of the importance of early recognition and intervention for bruxism in children. Materials and methods An analysis of scientific articles available in the PubMed and Google Scholar databases was conducted. Our research is supported by all relevant publications from recent years. The etiology, diagnosis, and treatment of bruxism in children were of particular interest in the study. This process involved the use of the following keywords: ‘bruxism’, ‘children’, ‘sleep bruxism’, ‘tooth wear’, ‘bruxism diagnosis’, ‘bruxism etiology’, ‘bruxism treatment’. Conclusions We evaluated 31 relevant publications. The results of the study indicate a variation in the prevalence of bruxism in children, oscillating between 13-49%. The etiology of this disorder is multidimensional and remains incompletely elucidated. The primary methods of diagnosing bruxism in younger patients include observation by parents or caregivers, a thorough health history and intraoral and extraoral dental examination. Physiotherapy and psychotherapy are recommended for the treatment of nocturnal bruxism in children. Prompt recognition of the disorder and implementation of appropriate therapy can help to halt the progression of motor dysfunction of the masticatory apparatus in children.

Global Prevalence of Sleep Bruxism and Awake Bruxism in Pediatric and Adult Populations: A Systematic Review and Meta-Analysis.

Background/Objectives: The purpose of this systematic review was to assess the global prevalence of sleep bruxism and awake bruxism in pediatric and adult populations. Methods: This systematic review was conducted by analyzing studies published from 2003 to 2023. The following keyword combination was utilized: prevalence, epidemiology, population, and bruxism. The PubMed database was analyzed, supplemented by manual searches using the Google search. Additionally, the snowballing procedure method was applied. A double assessment of the quality of publications was carried out to preserve the highest possible quality of evidence (e.g., Joanna Briggs Institute critical appraisal checklist). Analyses were conducted using the R statistical language. Results: The global bruxism (sleep and awake) prevalence is 22.22%. The global sleep bruxism prevalence is 21% and awake prevalence is 23%. The occurrence of sleep bruxism, based on polysomnography, was estimated at 43%. The highest prevalence of sleep bruxism was observed in North America at 31%, followed by South America at 23%, Europe at 21%, and Asia at 19%. The prevalence of awake bruxism was highest in South America at 30%, followed by Asia at 25% and Europe at 18%. Conclusions: One in four individuals may experience awake bruxism. Bruxism is a significant factor among women. It was observed that age is a significant factor for the occurrence of sleep bruxism in women. Among the limitations of the study is the lack of analysis of the prevalence of bruxism in Africa and Australia due to not collecting an adequate sample for analysis. The study was registered in the Open Science Framework (10.17605/OSF.IO/ZE786).

The Prevalence of Bruxism and Associated Factors Among Patients with Schizophrenia in Istanbul, Türkiye: A Cross-Sectional Study.

Schizophrenia is a severe and chronic neuropsychiatric disorder that involves profound impairment of psychopathology in cognition, emotion, perception, and other aspects of behavior. Factors, such as the nature of the disease, length of hospital stay, duration of illness, and side effects of psychotropic drugs, may contribute to poor oral health and the risk of developing bruxism in patients with schizophrenia. To evaluate the prevalence of bruxism and associated factors in patients with schizophrenia. This cross-sectional study was conducted in a single center with 211 patients with schizophrenia. Study participants were graded according to "probable" bruxism based on positive clinical inspection, with or without a positive self-report. The type of antipsychotic treatment used in participants was evaluated in three categories: typical antipsychotic monotherapy, atypical antipsychotic monotherapy, and a combination of both. Binary logistic regression models were used to evaluate associations between probable bruxism and different factors. The mean age of the study participants was 51.02 ± 9.29 years, and 112 (52.5%) were males. Probable bruxism was identified in 87 (41.2%) of the study participants. Younger age (AOR = 0.88, 95% CI = 0.838-0.928, P < 0.001), higher duration of illness (AOR = 1.50, 95% CI = 1.278-7.545, P < 0.001), and combination antipsychotic therapy (AOR = 3.042, 95% CI = 1.278-7.545, P = 0.015) were significant factors associated with probable bruxism among patients with schizophrenia on treatment. The relatively high prevalence of probable bruxism in patients with schizophrenia and its relation to antipsychotics was observed. There is a need for more research on the causes and treatment of bruxism in schizophrenia.

Bruxism in Children

Background: Bruxism can occur in children living or residing in slums areas, rural areas, remote and urban communities. The prevalence of bruxism among children varies in the literature. Bruxism is associated with sound during teeth clenching or involuntary teeth grinding, and this can disturb parents, guardian and family members. It can be diagnosed with clinical history, clinical examinationand use of electromyography and polysomnography. Method: An electronic literature search in science direct and goggle was done in December 2023 using the Population, Concept and Context framework. Search terms and keywords were combined by Boolean operators. Two independent investigators screened titles and abstracts of publications on bruxism among children. Original (primary) research articles with accessible full text were included for review, while review articles, systematic reviews, thesis, dissertations and perspectives related to bruxism among children were among articles excluded during screening. Original (primary) research articles related to voluntary tooth clenching,other oral habits and bruxism/tooth grinding among children with special health care needs were also excludedduring screening. Results: Abstract and full texts were screened using inclusion criteria by two independent investigators. The identified study was carried out in Egypt, Ugandaand South Africa respectively. Conclusion: Bruxism can occur among children.Itcan affect the quality of life of childrenwith tooth sensitivity, tooth attrition with wear facets, and psychological concerns.More studies from diverse ethnic population and countriesin Africa countries will fill the gaps in knowledge and add to the existing literature.

Epidemiology of Bruxism and Temporomandibular Joint Disorders (TMD) in Iranian Adults: A Cross-Sectional Study

Objective: The prevalence of bruxism in the literature has been reported differently. The aim of this study was to assess the prevalence of bruxism in patients aged 25–40 who were referred to Kerman Dental School. Methods: This analytical descriptive cross-sectional study was performed on 320 patients referred to the Department of Oral Medicine of Kerman Dentistry Faculty in the age range of 25 to 40 years old. The prevalence of bruxism as well as TMJ disorders were evaluated. Data were collected in a questionnaire and entered into SPSS version 24. Analyzing was done by a chi-square test at a significant level of 0.05. Results: The prevalence of bruxism was 23.8%, with superiority in women. Although clenching was observed in 95.5% of the patients, 84.4% showed premature contacts on teeth, most of them related to the non-working side, and 82.9% presented premature contacts on restorations, especially on the non-working side. Regarding TMD symptoms, pain was the most common (83.4%), and clicking and crepitus were seen in 42% and 6% of the patients, respectively. Also, in 63.7% of the subjects with bruxism, jaw deviation was observed, and 18.7% showed restricted jaw movement. Conclusion: The prevalence of bruxism in the studied population is in the range of similar studies. Regarding TMD, troublesome symptoms such as pain, jaw deviation, and limited mouth opening were the only ones significantly related to bruxism.

Prevalence of Bruxism in alcohol abusers: a systematic review conducted according to PRISMA guidelines and the cochrane handbook for systematic reviews of interventions

BackgroundBruxism, 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.MethodsA 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.ResultsThe 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.ConclusionsThis 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.

Prevalence of Bruxism in Children and Adolescents with Cerebral Palsy: Systematic Review and Meta-analysis.

To perform a systematic review and meta-analysis compiling data on the prevalence of bruxism in children and adolescents with cerebral palsy. Searches were carried out in PubMed/Medline, Web of Science, and Scopus databases to identify the articles published by February 2023. Two independent reviewers, and in duplicate, employed a two-stage process to select publications. The same two reviewers performed the data extraction. Studies were included when the following eligibility criteria were met: performed in children and/or adolescents with cerebral palsy and reporting bruxism. Potentially eligible studies were read in full and excluded that: not presented numerical data on the prevalence of bruxism; not reported how the bruxism was assessed; not reported data about the cerebral palsy; and not an observational study. The risk assessment of bias was assessed by the Newcastle- Ottawa Scale. After reading the titles and abstracts of the 358 identified articles, eight articles from 1966 to 2020 were included. The main reason for not including the studies was not to report data about bruxism (59.3%), and 44.5% were excluded for not reporting data from patients with cerebral palsy. The studies were carried out in schools, university hospitals, or centers for patients with special needs (Brazil, the United States, and Egypt). The pooled prevalence of bruxism in children and adolescents with cerebral palsy was 46% (95%CI: 0.38-0.55) after removing one study. The pooled prevalence of bruxism in children with cerebral palsy can be considered high since almost half of the studied population is affected by this condition. PROSPERO #CRD42021225781.

The prevalence of bruxism and oral parafunction activities among Israeli juveniles with autism spectrum disorder: A preliminary study during the COVID-19 pandemic

ABSTRACT Objective To evaluate the prevalence of oral habits, bruxism, and Temporomandibular Disorders (TMD) injuvenileswithautisticspectrumdisorder(ASD). Methods Data included 165 juveniles diagnosed with ASD, allocated to younger group aged 6 21 (n=86) and older group aged 13-21 (n=79). Results Sleep bruxism was reported by 26.7% in the younger group and by 5% in the older group. Awake bruxism was reported by 22% and 17.7%, respectively. Oral habits were reported by 43% of all participants, with similar rate in both groups. TMD related p ain was low in both groups (6.3% and 7% respectively). The influence of the COVID 19 pandemic on oral parafunction was moderate in the younger group (17.4%) and mild in the older group (8.6%), influence on bruxism was mild in both groups (5.8% and 2.5%, respectively). Conclusion The prevalence of bruxism and oral parafunctions was similar to the reported in the literature for the general population.

A Comprehensive Review on the Prevalence of Bruxism with Stress and Aggression

Bruxism is a type of neuro-psychic disease that influences the activity of the mandible and distorts multiple structures of the face and mouth muscles. This study goes through the complicated relationship between bruxism, stress, and aggression. The aim is to interpret the extensiveness of these three factors and evaluate the scientific perception of this. Psychological discomfort may manifest subtly as bruxism. A person having Bruxism is a spontaneous activity with the problem of clenching and grinding of teeth. It is a pervasive oral parafunctional activity. It accumulates growing recognition because of its complex connection with several serious psychological disorders. Bruxism is a type of neuro-psychic disease that influences the activity of the mandible and distorts multiple structures of the face and mouth muscles. According to previous studies, most bruxism is the result of suppressed stress which can occur due to lifestyle, and career pressure. People with severe anger issues can show signs of bruxism as a result of tension build-up in their oral cavity. As it is studied by various research, people show stages of bruxism in various stages of life depending on the situation they are struggling with. To shed light on the intricate interactions between stress, aggression, and oral habits, this review investigates the prevalence of bruxism in forensic contexts. We examine the body of research to clarify the possible applications of bruxism in forensic contexts, highlighting its importance in comprehending psychological profiles and behavioural patterns.

Effects of the COVID-19 Pandemic on College Students in Brazil.

The implementation of restrictive measures during the pandemic drastically changed the routine and habits of the population. In the academic sphere, the sudden closure of universities difficulted any advance planning. The objective of this study was to verify the effects of the pandemic on the routine, physical and mental health of students at a public university in southern Brazil. This is a cross-sectional study that applied a questionnaire from May to August 2020. The target population comprised 528 undergraduates. The questionnaire addressed questions about sociodemographic characteristics, physical and mental health. A response was obtained from 406 participants. During the quarantine period evaluated, the main results were: 66.2% reported worsening of anxiety symptoms; 57.6% declared that their physical health was "reasonable" to "bad". As for the quality of sleep there was an increase in 98.8% in the responses "bad sleep quality" and "very bad sleep quality"; increase in 26.6% for presence bruxism; 12.5% for orofacial pain, 3.8% for headache. It is concluded that there were several negative effects, among these effects, it was observed higher levels of anxiety, worsening physical health and quality of sleep, increase in the prevalence of bruxism, as well as the presence of orofacial pain and headache.

Presencia de bruxismo según tipo parálisis cerebral

ABSTRACT Purpose: to determine the presence of bruxism, according to the type of cerebral palsy. Methods: a descriptive, cross-sectional, quantitative study with a non-experimental design. A total of 55 children with cerebral palsy were evaluated, using an oral observation sheet, and data were analyzed by non-parametric tests of frequencies, percentages, arithmetic mean and descriptive statistics. Results: there was a majority of male children, with mean age 10.56 years. Sleep bruxism and daytime tooth clenching prevailed in the spastic cerebral palsy with 75% and 55.6% respectively, compared to the other types of cerebral palsy (p=0.034). In the characteristics of oral cavity, the presence of wear facets was observed, associated with all types of bruxism (p&lt;0.05). Conclusion: there was a high prevalence of bruxism in spastic cerebral palsy, evidencing the need to implement treatment options for this pathology in people presented with cerebral palsy, requiring more studies, with standardized diagnostic protocols and representative samples to evaluate the factors that influence the presence of several types of bruxism.

Prevalence of bruxism among college students

Evaluate the prevalence of bruxism and to analyze what are the possible associated factors with this condition in students of a Brazilian university. Methods: This was a cross-sectional study, with a sample of 230 students randomly selected among undergraduate courses at a university center. The dependent variable was the presence of awake bruxism and sleep bruxism. The independent variables were sociodemographic factors, smoking, alcohol consumption, oral habits and stress perception (Perceived Stress Scale- PSS 14). Descriptive statistics and bivariate analysis were used. Results: The prevalence of awake bruxism was 28.7% and was associated with the independent variables: course (degree program), gum chewing habits, chin hand placing, facedown sleeping and one-side biting. Sleep bruxism had a 7.0% prevalence and displayed association with gum chewing, pens/pencils/objects biting, tongue/lips/cheeks biting, nails biting and one-side biting. Perceived stress was not associated with either type of bruxism. Conclusion: Bruxism has an important prevalence among university students, especially when distinguishing between awake bruxism and sleep bruxism.

Bruxism, parafunctional oral habits and oral motor problems in children with spastic cerebral palsy: A cross-sectional study.

Individuals with spastic cerebral palsy are more predisposed to parafunctional oral activities and oral motor problems because of spasticity. The aim of the study was to evaluate the relationship between the gross motor function classification system score (GMFCS), age, bruxism, parafunctional oral habits and oral motor problems in children with cerebral palsy. This cross-sectional study included 63 children with spastic cerebral palsy, aged 3-18 years, with developmental disabilities. The relationship between parentally reported bruxism, parafunctional oral activity rates, oral motor problems, and GMFCS was analysed. The prevalence of bruxism was 52.4%, and the rate decreased as age increased. There was a greater likelihood of bruxism in individuals with tongue thrust (OR [95% CI] = 8.15 [1.4-47.3]) and swallowing problems (OR [95% CI] = 5.78 [1.3-24.68]). In children with spastic cerebral palsy, bruxism and the rate of parafunctional oral habits were high, thus affecting oral motor activities. A relationship was found between oral motor problems and increased GMFCS levels, but no relationship was found between bruxism and GMFCS levels. Children with spastic cerebral palsy who display tongue thrust or swallowing problems have an increased likelihood of presenting with bruxism.

Prevalence of Bruxism in Down Syndrome Patients: A Systematic Review and Metanalysis.

Bruxism is a parafunctional activity characterized by grinding or clenching of teeth and is a common oral health concern in individuals with Down syndrome (DS). Understanding the prevalence of bruxism in this population is crucial for developing effective management strategies. This systematic review and meta-analysis is aimed to investigate the prevalence of bruxism among individuals with DS and explore its association with other oral health issues; METHODS: A comprehensive search was conducted across multiple electronic databases to identify relevant studies. Cross-sectional and observational studies were included. Data on bruxism prevalence and associated factors were extracted, and a meta-analysis was performed using both fixed and random-effects models of MedCalc software. Heterogeneity among studies was assessed using I2 statistics. New Castle - Ottawa scale was used to evaluate methodological quality of the included studies RESULTS: Eight studies met the predefined inclusion criteria and were included in the analysis. Seven studies used a questionnaire to assess bruxism. The pooled proportion estimate for occurrence of Down's syndrome across the included studies was found to be 0.33 (95% CI: 0.22-0.45) as per the RE model and 0.35(95% CI: 0.31-0.450) as per FE model in the quantitative analysis. All studies exhibited good methodological quality CONCLUSION: This systematic review and meta-analysis provide evidence of a significant prevalence of bruxism among individuals with Down syndrome. The findings highlight the association of bruxism with other oral health issues and specific chromosomal abnormalities. Comprehensive oral health assessments, including diagnostic procedures like PSG, are essential for addressing the unique oral health needs of individuals with DS. Further studies are recommended with a valid tool for the diagnosis. Early interventions and management strategies need to be tailored to this population, considering the multifaceted nature of oral health concerns in individuals with DS.

Prevalence of Sleep Bruxism and Respiratory Disorders in Schoolchildren Aged 8 - 11 Years in Kerman, Iran: Pre-COVID Pandemic Phase

Background: Bruxism is a parafunctional oral activity defined as excessive teeth grinding or jaw clenching. This disorder causes damage to the teeth and deforms them. Objectives: This is the first phase of the sleep bruxism and respiratory disorders assessment study in Kerman, Iran, which evaluated respiratory disorders and sleep bruxism in schoolchildren aged 8 - 11 years between 2018 - 2019. Methods: A total of 573 primary school students aged 8 - 11 years were recruited for this cross-sectional study in Kerman between 2018 - 2019. The subjects were chosen randomly from 20 schools located throughout the city. Following permission from officials, 30 students from each school were admitted to the study randomly. The parents were invited to fill out a checklist that included a history of respiratory and sleep problems and signs of bruxism or abnormal jaw movements. Additionally, an examination was performed, and the symptoms of bruxism, such as tooth wear and restoration fractures, were documented. Results: The parents of 573 children were recruited to the study. The prevalence of bruxism and respiratory diseases was observed to be 20.6% (n = 118) and 26.5% (n = 152), respectively. The children with sound production had 2.3 times higher odds of bruxism prevalence than those without sound production (P = 0.004). However, children with temporomandibular joint and paranasal sinus sensitivity had 4.5 (P = 0.001) and 3.8 (P = 0.001) times higher odds, respectively. Additionally, the odds of bruxism prevalence were 1.4 times higher in children with respiratory disorders than those without (P = 0.001). Conclusions: Bruxism was common in children who had a respiratory disorder. Given the potential impact of bruxism on children’s dental health, it is important to pay special attention to the health status of children with respiratory disorders.

Prevalence of bruxism in obstructive sleep apnea syndrome (OSAS) patients: A systematic review conducted according to PRISMA guidelines and the cochrane handbook for systematic reviews of interventions.

Sleep bruxism (SB) and obstructive sleep apnea syndrome (OSAS) are two sleep-related conditions that have been associated with significantly conflicting results in literature. Understanding the prevalence of bruxism among OSA patients is crucial for identifying possible comorbidities and optimising treatment strategies. This systematic review aimed at analysing the prevalence of SB in OSAS sufferers and understanding the association between the two. Five online databases were searched for relevant articles in accordance with the PRISMA guidelines for conduction of systematic reviews. Studies reporting the prevalence of bruxism in OSAS patients and diagnosed through clinical assessments or polysomnography were included. Data extraction and quality assessment were performed independently by two reviewers. Methodological quality of the included studies was assessed using Risk of Bias In Non-randomised Studies of Interventions (ROBINS-I). A thorough search of literature yielded only two studies were eligible for this review. SB was found to be significantly present in the OSAS group. Despite methodological variations, the majority of studies reported higher rates of bruxism in OSAS patients compared to the general population or control groups. The results of this systematic review point to a significant association between bruxism and obstructive sleep apnea. Further research is required to determine a more precise prevalence rate and investigate the potential therapeutic implications of the bruxism-OSAS association that uses a standardised assessment techniques and larger sample sizes.

Publication performance and trends in bruxism research: A bibliometric analysis.

Bruxism is an umbrella term that encompass a multidimensional spectrum of masticatory muscle activities. The purpose of this study was to do a bibliometric analysis including citation performance in the research topic of bruxism, by using an innovative method including details of article title, author keyword, KeyWords Plus and abstracts. The data were retrieved 2022-12-19 from the Clarivate Analytics Web of Science Core Collection, and the online version of the Science Citation Index Expanded (SCI-EXPANDED) for studies published 1992 to 2021. To evaluate research trends, the distribution of keywords in the article title and author-selected keywords were used. The search yielded 3233 documents in SCI-EXPANDED, of which 2598 were of the document-type 'articles' published in 676 journals. The analysis of the articles revealed that "bruxism/sleep bruxism," "electromyography," "temporomandibular disorders" and "masticatory muscles" are the most used keywords by the authors. Further, the most frequently cited study was published 9 years ago and handles the present definition of bruxism. The most productive authors and those with the highest performance have some common features; they have several national and international collaborations; and they have published articles about the definition, aetiology/pathophysiology and prevalence of bruxism, all senior researchers in the field of TMD. Hopefully, based on this study, researchers and clinicians will have information to be stimulated to outline future research projects on bruxism-related aspects, and to initiate new international or multinational collaborations.
