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. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Aims: Immune‐related adverse events (irAEs) linked to the use of immune checkpoint inhibitors (ICIs) have become increasingly frequent. To perform a bibliometric and critical review of the general panorama of publications on oral mucosal lesions (OML) associated with ICIs. Methods and Results: Systematized searches were performed in four databases. The included studies were organized and bibliometric and clinical data were extracted and analyzed using VantagePoint and Microsoft Excel. Most of the 35 included studies were reports or case series (n = 33/94.2%). The American authors stood out (n = 17/48.5%), with the majority presenting only one publication. Independent groups carried out most of the publications (n = 31/88.5%). Over the years, publications have increased for users of nivolumab and pembrolizumab. In 21 studies (60%), OML were more common in men, between the 6th and 9th decades of life and who had lung carcinoma (n = 13/37.1%). Pembrolizumab (n = 17/48.5%) was the most used ICI. The patients were affected by one or more OML, including: ulcers (n = 28/80%) and erythema (n = 11/31.4%). Systemic corticosteroids (n = 24/68.5%) and the discontinuation of ICI use (n = 18/51.4%) were the main approaches used. Conclusion: OML related to the use of ICIs have become increasingly common. More accurate data need to be published. [ABSTRACT FROM AUTHOR]

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., Competing Interests: No conflicts of interest reported.

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.
