RESUMEN
BACKGROUND AND OBJECTIVES: This global bibliometric review aimed to investigate trends in publications relating to tinnitus and TMD. METHODS: A search was performed in eight databases (June/2022), by independent researchers with relevant keywords about tinnitus and TMD, without restriction of date or language. Original research or case report/series evaluating prevalence, association and risk related to tinnitus and TMD were included. Independent examiners selected studies by title and abstract and performed data extraction. Data about publication and researchers, study population, objective, study design and diagnostic criteria for tinnitus and TMD were exported to VintagePoint® for bibliometric analyses. Data about the direct association between tinnitus and TMD were extracted. RESULTS: One hundred and seventeen articles from 25 countries were included, most observational (68.4%) and evaluating association (N = 60; 44.8%). Among the 60 studies of association, 22 (36.6%) presented results of a direct association between the presence/absence of tinnitus and the presence/absence of TMD. Brazil (19.5%) and the United States (12.7%) were the countries with the most publications, and Dentistry (48.6%) was the main publication area. A growth in publications in Dentistry was observed in the past 30 years and in the past 10 years in Medicine. Half of the studies included the elderly population (50.2%). The main diagnostic criterion for both tinnitus (37.8%) and TMD (28%) was general questionnaires and/or self-report. CONCLUSION: There is a growing trend in publications relating to tinnitus and TMD, especially in Dentistry, with a predominance of observational and association studies in the elderly population using questionnaires and/or self-report. More research with robust diagnostic methods and other study designs should be encouraged in the future.

BACKGROUND/AIMS: The level of knowledge about traumatic dental injuries (TDI) of lay people from a national point of view has never been studied and there is currently a lack of validated research instruments on this issue. The present study aims to develop and validate a questionnaire (TDI-Q) to assess the knowledge of lay people about TDI, including participants from the five regions of Brazil. MATERIAL AND METHODS: TDI-Q was drafted, in Brazilian Portuguese, based on the recommendations of the International Association of Dental Traumatology (IADT). Before its application, TDI-Q was evaluated by dentists, lay people, linguists, and psychometrists. The questionnaire was applied to measure temporal stability at two distinct times, with an interval of 15-20 days between the two applications: test (n = 110) and retest (n = 50). The presence of floor and ceiling effects were investigated by analyzing the frequency of responses of the questionnaire; convergent construct validity was tested through Spearman's correlation; the Mann-Whitney test was applied to discriminant construct validity. Temporal stability and internal consistency were evaluated through intraclass correlation coefficient and Cronbach's alpha, respectively. RESULTS: The floor and ceiling effects were not observed (0.9% and 2.7%, respectively); convergent validity analysis indicated a positive and strong correlation (r = 0.50; p < .001). Significant discriminant construct validity (p < .05) was observed. Satisfactory internal consistency (α = 0.7) and temporal stability (ICC = 0.82, p < .001) were also achieved. CONCLUSION: TDI-Q proved to have good psychometric properties and to be a reliable tool for evaluating the knowledge of lay people regarding TDI in the Brazilian population.

Mouthguards (MGs) are essential devices for the protection of sports-related orofacial injuries. Mapping of the literature on this subject may help to guide future studies; therefore, this review aimed to characterize the research trends of studies related to MGs and dental injuries in sports activities through bibliometric analysis of in vivo studies concerning the frequency of MG use; knowledge, awareness, perception, and/or attitude about MGs; and adaptation (fit) of MGs in the mouth and/or prevention of traumatic dental injuries (TDIs). A literature search was performed in 6 databases for studies published up to April 2022. Text mining and analysis software was used to extract and evaluate data related to the study author, country, keywords, journal of publication, and year. Additionally, data related to the type of study, outcome, study population, age group, evaluation method, type of MG, sport classification, and sport category were extracted and analyzed. Of 6140 records identified, 222 were included in the analysis. Most of the articles came from the United States (n = 39; 17.5%) and dentistry journals (n = 145; 65.3%). The journal Dental Traumatology (n = 60; 27.0%) presented the highest number of publications. Most studies were observational (n = 195; 87.8%) and evaluated the frequency of MG use (n = 163; 44.4%). Studies were carried out in athletes (n = 181; 82.6%) and adults (n = 169; 49.1%) using questionnaires or interviews for assessment (n = 206; 84.1%). Only 89 (40.1%) studies evaluated the type of MG, mostly involving contact sports. Custom-made MGs were most commonly studied. More studies involving coaches, dentists, and child and teenaged athletes are warranted to help prevent sportsrelated TDIs in young teeth, mainly through interventional studies on the perceptions of and knowledge about MGs among these populations.

BACKGROUND AND OBJECTIVES: To present a world panorama of the published papers on bruxism in children and adolescents, emphasising the characteristics of studies related to the sleep features of these patients. METHODS: Literature searches were conducted in six databases without language or date restrictions. Data on the titles, types of study, main subjects, countries of origin, keywords, years of publication, authors and their network collaborations, journals and sleep studies were extracted and analysed using VantagePoint™ software. RESULTS: A total of 725 studies met the eligibility criteria. Most included only children (75.31%), with observational design (66.34%), and risk or aetiology (53.93%) as the main subject. Brazil (18.06%) and Brazilian authors (54.84%) had the largest number of studies, with a low amount of network collaboration. The Journal of Oral Rehabilitation published most of the studies (6.2%); publications in this field have grown considerably from 2000 to 2020. Of the studies, 123 (16.96%) included sleep studies; night sweating, restless sleep, sleep talking, mouth breathing, snoring, obstructive sleep apnoea syndrome, sleep-disordered breathing, nightmares, poor sleep quality and duration, and daytime naps were significantly associated with bruxism in most. CONCLUSION: Studies on bruxism in children and adolescents have increased in the past 20 years, with most being observational, and risk or aetiology as the main subject. Brazil and the Journal of Oral Rehabilitation have published most in the field. Sleep studies have shown some features associated with bruxism, such as night sweating, restless sleep, somniloquy, snoring, breathing problems, nightmares, daytime naps, and poor sleep quality and duration.

OBJECTIVES: Given that current literature largely dissociates dental malocclusion and bruxism, the objective of this study was to gather, through a systematic review, scientific evidence to support their relationship. METHODOLOGY: This study was performed according to the PECO strategy (where P = general population; E = dental malocclusion; C = no dental malocclusion; and O = bruxism). Literature searches were conducted without language or date restrictions in the following databases: PubMed, Scopus, the Web of Science, the Cochrane Library, LILACS/BBO via VHL and the grey literature. The search strategy included Medical Subject Headings/DECs, synonyms and free terms relevant to each database, with no age restrictions applied. Once the relevant data were extracted from the articles, the Fowkes and Fulton guidelines were followed to assess the quality and risk of bias. For quantitative analysis, dental malocclusions were divided into groups according to their type in order to perform odds ratio (OR) meta-analyses with 95% confidence intervals (CI) using the Review Manager software program (Cochrane, London, UK). The level of certainty of evidence was demonstrated through the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). RESULTS: After 1,502 studies found, 10 studies were included for qualitative analysis and nine for quantitative synthesis. Four studies presented high methodological quality. Five meta-analyses suggested a non-association between bruxism and Angle class I (OR: 1.05, 95% CI: 0.41-2.69; P = .92; I2 = 84%), Angle class II (OR: 1.49, 95% CI: 0.77-2.87; P = .23; I2 = 71%) or Angle class III (OR: 0.77, 95% CI: 0.31-1.93; P = .58; I2 = 0%). Bruxism was associated with children who did not present with a posterior crossbite (OR: 0.70, 95% CI: 0.51-0.96; P = .03; I2 = 27%) and present crowding (OR: 1.53, 95% CI: 1.03-2.26; P = .03; I2 = 0%). The GRADE analysis presented a very low quality of evidence. CONCLUSION: Individuals who present with bruxism have a greater chance of crowding. However, bruxism is not associated with the presence of any of the other malocclusions evaluated.

The objective of the research was to examine the scientific literature concerning restorative materials with bioactive properties for the purpose of covering dentin. Searches were performed in various databases including MEDLINE, Scopus, Web of Science, Cochrane Library, Lilacs/BBO, and Embase. Inclusion criteria involved studies that utilized the terms "dentin" and "bioactive", along with "ion-releasing", "smart materials", "biomimetic materials" and "smart replacement for dentin". The information extracted included the title, authors, publication year, journal and the country of affiliation of the corresponding author. The studies were categorized based on their study design, type of material, substrate, analytical method, and bioactivity. A total of 7161 records were recovered and 159 were included for data extraction. Most of the publications were in vitro studies (n = 149), testing different types of materials in sound dentine (n = 115). Most studies were published in Dental Materials (n = 29), and an increase in publications could be observed after the year 2000. Most of the articles were from the USA (n = 34), followed by Brazil (n = 28). Interfacial analysis was the most investigated (n = 105), followed by bond strength (n = 86). Bioactivity potential was demonstrated for most tested materials (n = 148). This review presents insights into the current trends of bioactive materials development, clearly showing a severe lack of clinical studies.
RESUMEN
Purpose: To evaluate the association between attention-deficit/hyperactivity disorder (ADHD) symptoms reported by parents and the variables sleep problems, possible sleep bruxism, possible awake bruxism and dental trauma (DT), and its mode of occurrence in children and adolescents.
Methods: A cross-sectional study was conducted with the parents of 144 four- to 16-year-old subjects through a questionnaire on demographics, subjects' sleep, self-reported bruxism and DT mode of occurrence. The Swanson, Nolan and Pelham scale IV was used to assess ADHD signs and subtypes. Bivariate and multivariate analysis were performed (P <0.05).
Results: The subjects' mean age was 7.9 years (±2.8 years) and 50.7 percent were boys. DT was reported in 80 percent of those with the hyperactive/impulsive subtype (ADHD-HI) and 72.7 percent of those with the combined subtype (ADHD-C). DT was caused solely by falls in the ADHD-C and inattention subtypes (ADHD-I). ADHD-C was associated with somniloquy (prevalence ratio [PR]=1.075; P =0.010). ADHD-HI was associated with bad sleep quality (PR=1.194; P =0.005), possible sleep bruxism (PR=1.088, 95% confidence interval=1.006 to 1.176; P =0.034), possible awake bruxism (PR=1.146; P =0.024) and sleep duration (PR=0.88; P =0.02).
Conclusion: ADHD-C and -HI subtypes were associated with sleep characteristics. Possible sleep and awake bruxism were associated with symptoms of ADHD-HI. Despite no significant association, DT was present in most ADHD subjects, mostly due to falls.

OBJECTIVE: This study aimed to develop, validate, and apply a scale assessing knowledge of sleep-related myths and truths and associate it with sociodemographic factors. METHODS: A scale with 15 questions was created, containing statements about the characteristics of sleep and related to sleep and dentistry. Each answer ranged from 0 to 4 points, generating a total score from 0 to 60, where higher scores represented greater knowledge. A preliminary study with 200 people assessed its convergent and discriminant construct validity, internal consistency, and temporal stability. The main study included 1965 respondents over 18 years. Additionally, sociodemographic data were collected and a classification of the level of knowledge was performed. Data were analyzed with Student's t-test and one-way ANOVA (p < 0.05). RESULTS: The questionnaire showed convergent (p < 0.001) and discriminant (p = 0.024) construct validity, internal consistency (alpha = 0.7), and temporal stability (ICC = 0.87). In the main study, 90.3% of the participants had moderate and high knowledge, with the score ranging from 24 to 58. Adults over 28 years old (p < 0.001), from the southern region of Brazil (p < 0.001), who lived in capital or metropolitan areas (p < 0.001), with higher education (p < 0.001), without religion (p < 0.001), and involved in dentistry (p < 0.001) had greater knowledge than their peers. CONCLUSIONS: The scale presented good psychometric properties. Most participants had moderate and high knowledge on sleep, with a difference in knowledge related to the age, region and area of residence, education, involvement with dentistry, and religion.

Objetivo: Avaliar a qualidade e a confiabilidade do conteúdo de vídeos sobre Odontologia do Sono no YouTube™. Métodos: Foi realizada uma busca no YouTube™, utilizando o termo "Odontologia do Sono", na qual selecionou-se os 100 primeiros vídeos para análise realizada por dois pesquisadores. Foram incluídos vídeos sobre o tema, na língua portuguesa brasileira, com no máximo 24 minutos. Foram extraídos: título, data, duração, visualização, curtida, fonte, público-alvo, objetivo e assunto. A qualidade foi avaliada através da Escala de Qualidade Global (EQG), e a confiabilidade, através da adaptação de um índice previamente publicado, ambos pontuando até 5 pontos, onde mais pontos significavam maior qualidade e confiabilidade. Foram realizados os testes de Mann-Whitney U, Kruskal-Wallis e a correlação de Spearman (p < 0,05). Resultados: 58 vídeos foram incluídos, cuja mediana da duração foi 2,4 ± 7,6 minutos. A maioria dos vídeos era produzida por cirurgiões-dentistas (CD) (75,9%; n = 44), sobre apneia (96,6%; n = 56), com o objetivo educacional/informativo (65,5%; n = 38) e direcionado para leigos (58,6%; n = 34). A maioria apresentou mediana baixa de 2,0 ± 1,0 na EQG (41,4%; n = 24), e na escala de confiabilidade, a mediana de 3,0 ± 1,0 (60,3%; n = 35). Houve correlação moderada da EQG (p = 0,62; p < 0,01) e da confiabilidade (ρ = 0,41; p < 0,01) com a duração do vídeo, e também entre EQG e confiabilidade (ρ = 0,66; p < 0,01). Vídeos educacionais/informativos, produzidos por CD, e direcionados a leigos, apresentaram uma maior EQG e confiabilidade (p < 0,01). Vídeos que incluíam bruxismo tinham maior EQG (p = 0,01). Programas de televisão e vídeos que não eram comerciais apresentaram maior confiabilidade (p < 0,05). Conclusão:A maioria dos vídeos possuía qualidade baixa e confiabilidade moderada. Vídeos educacionais/informativos, feitos por CD, direcionados a leigos, que incluíam bruxismo, programas de televisão e que não eram comerciais, apresentaram maior qualidade e confiabilidade.
Aim: To assess the quality and reliability of video content on Dental Sleep Medicine on YouTube™. Methods: A search was performed on YouTube™ using the term "Dental Sleep Medicine". The first 100 videos were selected for analysis by two researchers. Videos on the subject were included, in Brazilian Portuguese with a maximum of 24 minutes. The following data were extracted: title, date, duration, views, likes, source, target audience, objective and subject. Quality was assessed using the Global Quality Scale (GQS), and reliability using a previously published index adapted, both ranging from 1 to 5 points, where more points meant greater quality and reliability. Spearman correlation, Mann-Whitney U, and Kruskal-Wallis test (p < 0.05) were performed. Results: 58 videos were included, with a median duration of 2.4 ± 7.6 minutes. Most of the videos were produced by dentists (75.9%; n = 44), about apnea (96.6%; n = 56), with an educational/informational objective (65.5%; n =38), and aimed at laypeople (58.6%; n = 34). Most had a low median of 2.0 ± 1.0 on the GQS (41.4%; n = 24), and on the reliability scale, the median was 3.0 ± 1.0 (60.3%; n = 35). There was a moderate correlation between both GQS (ρ = 0.62; p < 0.01) and reliability (ρ = 0.41; p < 0.01) with video duration, and also between GQS and reliability (ρ = 0 .66; p < 0.01). Educational/informational videos, produced by dentists, and aimed at laypeople showed higher GQS and reliability (p < 0.01). Videos that included bruxism had higher GQS (p = 0.01). Television programs and non-commercial videos were more reliable (p < 0.05). Conclusion: Most videos had low quality and moderate reliability. Educational/informational videos, made by dentists, aimed at laypeople, that included bruxism, television programs, and that were not commercials, presented higher quality and reliability.
