Understanding Health Care Students' Perceptions, Beliefs, and Attitudes Toward AI-Powered Language Models: Cross-Sectional Study.

BACKGROUND: ChatGPT was not intended for use in health care, but it has potential benefits that depend on end-user understanding and acceptability, which is where health care students become crucial. There is still a limited amount of research in this area. OBJECTIVE: The primary aim of our study was to assess the frequency of ChatGPT use, the perceived level of knowledge, the perceived risks associated with its use, and the ethical issues, as well as attitudes toward the use of ChatGPT in the context of education in the field of health. In addition, we aimed to examine whether there were differences across groups based on demographic variables. The second part of the study aimed to assess the association between the frequency of use, the level of perceived knowledge, the level of risk perception, and the level of perception of ethics as predictive factors for participants' attitudes toward the use of ChatGPT. METHODS: A cross-sectional survey was conducted from May to June 2023 encompassing students of medicine, nursing, dentistry, nutrition, and laboratory science across the Americas. The study used descriptive analysis, chi-square tests, and ANOVA to assess statistical significance across different categories. The study used several ordinal logistic regression models to analyze the impact of predictive factors (frequency of use, perception of knowledge, perception of risk, and ethics perception scores) on attitude as the dependent variable. The models were adjusted for gender, institution type, major, and country. Stata was used to conduct all the analyses. RESULTS: Of 2661 health care students, 42.99% (n=1144) were unaware of ChatGPT. The median score of knowledge was "minimal" (median 2.00, IQR 1.00-3.00). Most respondents (median 2.61, IQR 2.11-3.11) regarded ChatGPT as neither ethical nor unethical. Most participants (median 3.89, IQR 3.44-4.34) "somewhat agreed" that ChatGPT (1) benefits health care settings, (2) provides trustworthy data, (3) is a helpful tool for clinical and educational medical information access, and (4) makes the work easier. In total, 70% (7/10) of people used it for homework. As the perceived knowledge of ChatGPT increased, there was a stronger tendency with regard to having a favorable attitude toward ChatGPT. Higher ethical consideration perception ratings increased the likelihood of considering ChatGPT as a source of trustworthy health care information (odds ratio [OR] 1.620, 95% CI 1.498-1.752), beneficial in medical issues (OR 1.495, 95% CI 1.452-1.539), and useful for medical literature (OR 1.494, 95% CI 1.426-1.564; P<.001 for all results). CONCLUSIONS: Over 40% of American health care students (1144/2661, 42.99%) were unaware of ChatGPT despite its extensive use in the health field. Our data revealed the positive attitudes toward ChatGPT and the desire to learn more about it. Medical educators must explore how chatbots may be included in undergraduate health care education programs.

Clear aligner's adverse effects: A systematic review protocol.

With the growing popularity of clear aligners, more patients have chosen to use them instead of traditional orthodontic braces to correct their malocclusions. Clear aligners offer distinct advantages over conventional fixed braces, such as limited aesthetic impact, the convenience of easily removing them for meals, improved accessibility for brushing and flossing, and a treatment approach that avoids the use of metal, minimizing potential irritation to the cheeks and gums. Manufacturers point out a disadvantage that can be administered in this type of treatment. Still, to our knowledge, a comprehensive review of the published literature assessing the adverse/negative effects of clear aligners has not yet been conducted. A systematic review, with or without meta-analysis, will be performed. The inclusion criteria will be studies involving individuals using clear aligners and reporting potential adverse/negative effects during or after treatment. No restrictions about time or language will be applied. The studies screening will be conducted in two stages. Two independent reviewers will initially evaluate the title and abstract under the eligibility criteria. Subsequently, the same two reviewers will examine the articles' full text in-depth. The results will be synthesized in the form of a narrative description and incorporate a meta-analysis if justified. Furthermore, we will present details regarding the sample characteristics, intervention, study objectives, methodologies employed, and primary findings. This study aims to investigate the potential adverse effects and their frequency among orthodontic patients wearing clear aligners. Moreover, the outcomes of this review have the potential to illuminate specific inherent limitations of aligner therapy as a comprehensive orthodontic approach.

Prevalence of awake Bruxism: A systematic review.

OBJECTIVES: To identify the prevalence of Awake Bruxism (AB). SOURCES: The electronic search was done in Embase, PubMed/MEDLINE, LILACS, Livivo, Scopus, and Web of Science databases up to January 2nd, 2023. The search strategies combined terms such as "bruxism," "awake," and related terms when conducting searches in databases. Grey literature was consulted through Google Scholar, ProQuest, and OpenGrey. STUDY SELECTION: Two independent reviewers participated in the study selection stages and included observational studies assessing the prevalence of AB, detected using reporting feedback (self or family report), clinical examination, and/or instrumental methods, regardless of the sex and age of the population. DATA: Methodological quality was assessed using the Joanna Briggs Institute's checklist for prevalence studies. Ratio meta-analyses were performed using R Statistics software. RESULTS: From a total of 3,083 studies identified by the searches on databases, 322 articles were reviewed the full-text and a total of 81 (quantitative synthesis) and 83 (narrative synthesis) studies were included. Only fifteen studies reached complete methodological quality. Two overall meta-analyses were performed, grouped based on convenience and population-based samples. The overall prevalence for possible AB was 32.08 % and 16.16 %, respectively. For the subgroup analyses, the prevalence rate showed a wide variation in different studied populations, approximately 14 %-32 % for women and 19 %-30 % for men, for population-based and convenience studies, respectively. CONCLUSION: Possible AB prevalence was set from 16 % to 32 %. Studies with probable AB and definitive AB are still necessary. CLINICAL SIGNIFICANCE: Studying the prevalence of waking bruxism is of interest to both dentists and patients. Knowing the probability of patients having awake bruxism allows the dentist to offer comprehensive preventive approaches to patients, avoiding deleterious consequences resulting from this condition. The present study reveals that the condition of bruxism during wakefulness is present in one out of every six adult patients studied. In pediatric patients, although this condition seems to be equally present, not enough studies were found to support this information for probable and definitive bruxism.

Tooth wear prevalence in individuals with Down syndrome: a systematic review.

OBJECTIVES: This systematic review investigated the prevalence of tooth wear between patients with and without Down syndrome. METHODS: Six databases (Embase, LILACS, Livivo, PubMed, Scopus and Web of Science) and grey literature (Google Scholar, OpenGrey and ProQuest) were searched until March 7, 2022. Observational studies were included to assess the differences in tooth wear prevalence and/or severity in Down syndrome and non-syndromic controls. Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) recommendations were followed. Three reviewers independently screened studies, extracted data, assessed the methodological quality (Joanna Briggs Institute) and graded the certainty of evidence through the Grading of Recommendations, Assessment, Development, Evaluation (GRADE) approach. Results were summarized through meta-analyses using a random-effects model. The protocol was registered at PROSPERO (CRD42021266997). RESULTS: Of the 1382 records identified, six cross-sectional studies were included. Individuals with Down syndrome had a higher prevalence and were more likely to have tooth wear than individuals without Down syndrome (44% × 15%; OR = 4.43; 95% CI 3.17-6.18; p < 0.00001; I2 = 8%). Also, the severity of tooth wear was higher in the Down syndrome group (n = 275) compared with the controls (n = 294). The certainty of evidence analysis was very low. CONCLUSIONS: Based on very low certainty of the evidence, patients with Down syndrome had a higher prevalence and likelihood and severity of tooth wear when compared to those without Down syndrome. CLINICAL RELEVANCE: Screening early tooth wear lesions should be carefully done in the Down syndrome population since its occurrence is remarkable compared to the general population.

Worldwide prevalence of geographic tongue in adults: A systematic review and meta-analysis.

To identify the prevalence of geographic tongue in patients >18 years. A systematic literature review was performed in search of population-based observational studies. Searches were performed using five main databases: Embase, LILACS, PubMed, Scopus and Web of Science; and three gray literature sources: Google Scholar, ProQuest, and OpenGrey. In addition, a manual search in the reference list and consultation with experts on the topic studied were performed. Methodological quality was assessed using the Joanna Briggs Institute's checklist for prevalence studies. Ratio meta-analyses were performed using JAMOVI. Initially, 3046 studies were identified. After a two-phase selection, 11 studies were included for quantitative synthesis. Two studies were classified as of low methodological quality, five studies as of moderate quality, and four as of high quality. Two types of prevalence were analyzed: by period and point. Three studies were included in the period prevalence meta-analysis, and the prevalence was 3% (Confidence interval [CI]: 0.4%-5.5%, n = 9813). Eight studies were included in the point-prevalence meta-analysis, and the prevalence was 3% (CI: -0.2% to 5.5%, n = 10,967). Although there are phases of exacerbation and remission in geographic tongue, prevalence and period prevalence were similar. Approximately one in 30 adults has a geographic tongue.

Disocclusion guides in occlusal splints on temporomandibular disorders and sleep bruxism: a systematic review.

OBJECTIVE: To determine the best disocclusion guidance in occlusal splints (OSs) to manage and treat temporomandibular disorder (TMD) and sleep bruxism (SB). STUDY DESIGN: The research was conducted on 7 major electronic databases and 3 gray literature sources. We included randomized trials, nonrandomized clinical trials, and before-and-after studies. The risk of bias (RoB) was assessed by Joanna Briggs Institute of Critical Appraisal Tools. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to grade the certainty of evidence. RESULTS: Qualitative synthesis included 16 surveys reporting data from 620 participants. Canine guidance (CG) was widely searched. Bilateral balanced occlusion (BBO) and CG significantly decreased pain levels compared with the placebo splint. Comparing between OS and absence of therapy, only CG was assessed and showed significant improvements on mouth opening, pain, sleep quality, and muscle activity. When compared different guide types among themselves, no significant improvement was founded in any evaluated outcome. Three studies presented high RoB, 7 presented moderate RoB, and 6 presented low RoB. CONCLUSIONS: It is suggested there is not enough evidence to support that there are any specific kind of guidance responsible for improving evaluated outcomes on TMD and SB.

Prevalence of SARS-CoV-2 infection among oral health care workers worldwide: A meta-analysis.

OBJECTIVES: This systematic review aimed to answer the following question 'What are the worldwide prevalence of SARS-CoV-2 infection and associated factors among oral health-care workers (OHCWs) before vaccination?' METHODS: Seven databases and registers as well as three grey databases were searched for observational studies in the field. Paired reviewers independently screened studies, extracted data and assessed the methodological quality. Overall seroprevalence for SARS-CoV-2 infection was analysed using a random-effect model subgrouped by professional category. Meta-regression was used to explore whether the Human Development Index (HDI) influenced the heterogeneity of results. The associated factors were narratively evaluated, and the certainty of the evidence was assessed using the GRADE approach. RESULTS: Seventeen studies were included (five cohorts and twelve cross-sectional studies), summing 73 935 participants (54 585 dentists and 19 350 dental assistants/technicians) from 14 countries. The overall estimated pooled prevalence of SARS-CoV-2 infection among OHCWs was 9.3% (95% CI, 5.0%-14.7%; I2  = 100%, p < .01), being 9.5% for dentists (95% CI, 5.1%-15.0%; I2  = 100%, p < .01) and 11.6% for dental assistants/technicians (95% CI, 1.6%-27.4%; I2  = 99.0%, p < .01). In the meta-regression, countries with lower HDI showed higher prevalence of SARS-CoV-2 infection (p = .002). Age, comorbidities, gender, ethnicity, occupation, smoking, living in areas of greater deprivation, job role and location/municipalities, income and protective measures in dental settings were associated with positive serological SARS-CoV-2 test, with very low certainty of evidence. CONCLUSIONS: The SARS-CoV-2 virus infected 9.3% of the OHCWs evaluated worldwide before vaccination. OHCWs should be included in policy considerations, continued research, monitoring and surveillance (PROSPERO CRD42021246520).

Association between genetic polymorphisms in the melatonin receptor type 1 A gene and sleep bruxism.

OBJECTIVE: This study evaluated whether single nucleotide polymorphisms in the melatonin receptor type 1 A gene are associated with sleep bruxism in a Brazilian population. DESIGN: Individuals with suspected sleep-related problems were evaluated using polysomnography, following the recommendations proposed by the American Academy of Sleep Medicine and the Research Diagnostic Criteria for Temporomandibular Disorders. Deoxyribonucleic acid (DNA) samples were collected, and three single nucleotide polymorphisms in the melatonin receptor type 1 A gene (rs13140012, rs6553010, and rs6847693) were selected and genotyped using real-time polymerase chain reaction (RT-PCR). Chi-square and odds ratio tests were used to analyze genotypes and alleles individually, while using the plink software for haplotypes. A confidence interval of 95% was considered, and statistical significance was set at p < 0.05. RESULTS: This study included 48 individuals aged between 21 and 80 years, with 27 males and 21 females. From this sample, 17 individuals were diagnosed with sleep bruxism and 31 without bruxism. No associations were found between sleep bruxism and single nucleotide polymorphisms in either the genotypic, allelic, dominant, or recessive models (p > 0.05). Haplotype genetic analysis also did not reveal any association between single nucleotide polymorphisms and sleep bruxism (p > 0.05). CONCLUSION: The genetic polymorphisms rs6553010, rs13140012, and rs6847693 were not associated with sleep bruxism in the studied population.

Critical appraisal of systematic reviews of intervention in dentistry published between 2019-2020 using the AMSTAR 2 tool.

Introduction The number of systematic reviews (SRs) in dentistry published each year has grown considerably, and they have been essential in clinical decision-making and health policy.Objective The objective is to critically appraise SRs of intervention in dentistry using the 'A Measurement Tool to Assess Systematic Reviews 2' (AMSTAR 2) tool published within one year.Methods A search in the Medline/PubMed database was performed. The SRs were identified in two phases. The first phase identified SRs of interventions in dentistry by title and abstract. In the second phase, the full text was read, applying the eligibility criteria. Three calibrated reviewers methodologically assessed all SRs identified using the AMSTAR 2 tool. Data were analysed descriptively, and SRs were grouped according to methodological quality as moderate/high and low/critically low. A logistic regression model was applied to explore the associations between methodological quality and the study's characteristics.Results Two hundred and twenty-two SRs were included. The methodological quality of the SRs included in this study were: critically low (56.8%), low (27.9%), moderate (14.4%) and high (0.9%), according to AMSTAR 2. There were no statistical differences between moderate/high and low/critically low methodological quality and publication year, continent, journal Impact Factor and dental speciality.Conclusion Less than 1% of recently published SRs in dentistry were classified with high methodological quality. We hope that this study will alert researchers about the need to improve the methodological quality of SRs.

Sleep bruxism and obstructive sleep apnea: association, causality or spurious finding? A scoping review.

STUDY OBJECTIVES: To evaluate the available evidence on the putative relationships between sleep bruxism (SB) and, obstructive sleep apnea (OSA) to assess the extent of research on this topic, and to formulate suggestions for future research. METHODS: A scoping review including studies examining temporal and overall association and prevalence of SB and OSA was performed. Six main databases and gray literature were searched. The studies selection was conducted by three independent reviewers. A narrative synthesis of the results was carried out. RESULTS: Thirteen studies in adults and eight studies in children were finally included. The median of concomitant conditions prevalence was 39.3% in adults and 26.1% in children. Marked methodological variability was identified among studies in adults and even more when we compared detection methods in children. No significant association between OSA and SB emerged in most studies in adults, while an association may be possible in children. CONCLUSIONS: Based on the current literature, it is not possible to confirm that there is a relationship between SB and OSA in adults. In patients under pediatric care, although this association seems plausible, there is currently insufficient supportive evidence. Standardized validated methodologies for identifying SB should be consistently used in both populations before reaching any conclusion regarding such association. Furthermore, assessment of shared phenotypes between patients with SB and patients with OSA may reveal new insights that will contribute to personalized approaches aiming to optimize the management of such comorbidities.

Effects of stabilization splints on the signs and symptoms of temporomandibular disorders of muscular origin: A systematic review.

OBJECTIVE: To assess effects of stabilization splints on signs and symptoms of temporomandibular disorders of muscular origin compared to other treatments. METHODS: A search for articles via six electronic databases and gray literature was conducted. The risk of bias was evaluated with the Cochrane Collaboration tool. The Grading of Recommendations Assessment, Development and Evaluation approach determined the certainty of evidence. RESULTS: Ten articles were included. Stabilization splints (n = 160 subjects) were reported to be as effective as other treatments (n = 209 patients) on analyzed outcomes (pressure pain threshold, pain during chewing, mouth opening, spontaneous pain intensity and by palpation). Five studies were judged at low and five at some concerns of risk of bias. The certainty of evidence was very low for all outcomes. CONCLUSION: Positive effect on signs and symptoms of temporomandibular disorders of muscular origin, when managed with stabilization splint, could not be confirmed or refuted.

Mental health effects prevalence in children and adolescents during the COVID-19 pandemic: A systematic review.

BACKGROUND: The COVID-19 pandemic health crisis has changed household and school routines leaving children and adolescents without important anchors in life. This, in turn, can influence their mental health, changing their behavioral and psychological conditions. AIMS: To systematically review the literature to answer the question: "What is the worldwide prevalence of mental health effects in children and adolescents during the COVID-19 pandemic?". METHODS: Embase, Epistemonikos database, LILACS, PsycINFO, PubMed, Scopus, Web of Science, and World Health Organization Global literature on coronavirus disease were searched. Grey literature was searched on Google Scholar, Grey Literature Report, and Preprint server MedRxiv. Observational studies assessing the prevalence of mental health effects in children and adolescents during the COVID-19 pandemic were included. Four authors independently collected the information and assessed the risk of bias of the included studies. RESULTS: From a total of 11,925 identified studies, 2873 remained after the removal of the duplicated records. Nineteen studies remained after the final selection process. The proportion of emotional symptoms and behavior changes varied from 5.7% to 68.5%; anxiety 17.6% to 43.7%, depression 6.3% to 71.5%, and stress 7% to 25%. Other outcomes such as the prevalence of post-traumatic stress disorder (85.5%) and suicidal ideation (29.7% to 31.3%) were also evaluated. LINKING EVIDENCE TO ACTION: Overall findings showed that the proportion of children and adolescents presenting mental health effects during the COVID-19 pandemic showed a wide variation in different countries. However, there was a trend toward mental health issues. Therefore, policymakers, healthcare planners, youth mental health services, teachers, parents, and researchers need to be prepared to deal with this demand.

Is there an association of genetic polymorphisms of the catechol-O-methyltransferase gene (rs165656 and rs174675) and the 5-hydroxytryptamine receptor 2A gene (rs4941573 and rs6313) with sleep bruxism in individuals with obstructive sleep apnea?

OBJECTIVE: To evaluate the association of single-nucleotide polymorphisms within the catechol-O-methyltransferase and 5-hydroxytryptamine receptor 2A genes with sleep bruxism in individuals diagnosed with obstructive sleep apnea. DESIGN: Sixty-nine individuals with suspected sleep-related problems were evaluated by polysomnography, following the recommendations of the American Academy of Sleep Medicine. Deoxyribonucleic acid (DNA) samples were collected only from 48 of the study participants because of missing polysomnographic data. DNA samples were collected and two single-nucleotide polymorphisms in the 5-hydroxytryptamine receptor 2A encoding HTR2A gene (rs4941573 and rs6313) and two in the catechol-O-methyltransferase gene (rs165656 and rs174675) were selected to be genotyped using real-time polymerase chain reaction. The association between sleep bruxism and genetic polymorphisms was investigated by recessive and dominant models. Association analyses were performed using a 95% confidence interval and the level of statistical significance was p < 0.05. RESULTS: From the 69 study participants, 48 were included in the polymorphism analysis and sleep bruxism was present in 35.4%. No significant differences were observed in the dominant and recessive models (p > 0.05). Haplotype and diplotype analyses revealed the predicted four haplotypes and two diplotypes were not associated with sleep bruxism. CONCLUSION: Polymorphisms rs174675 and rs165656 in the catechol-O-methyltransferase gene and rs4941573 and rs6313 in the 5-hydroxytryptamine receptor 2A gene were not significantly associated with sleep bruxism in individuals with obstructive sleep apnea.

Clinical performance of short versus standard dental implants in vertically augmented bone: an overview of systematic reviews.

OBJECTIVE: To answer the question: What do we know so far about the clinical performance of short implants (≤ 7 mm) when compared to standard length implants in vertically augmented bone, as well as which is the overall confidence of the systematic reviews (SRs) about this topic? MATERIALS AND METHODS: An overview of SRs was conducted. The searches were performed in six electronic databases and grey literature. SRs about short (≤ 7 mm) versus standard dental implants performance in vertically augmented bone were included. The assessed outcomes were marginal bone loss (MBL), implant survival (IS), prosthetic (PC) and biological complications (BC), costs, surgical time, and patient satisfaction. AMSTAR 2 was used to evaluate the overall confidence of included SRs. RESULTS: Thirteen SRs were included. Nine of twelve SRs reported a lower MBL for the short implant group. All the included SRs showed no difference in the IS between groups. A higher rate of BC was reported for standard-length implants in four out of five SRs. No differences regarding PC were reported in four of five SRs. Information related to patient preference, cost, and surgery time were underreported. The confidence evaluation of the SRs was stratified as low for five SRs and critically low for eight SRs. CONCLUSIONS: In an overall low-to-very low confidence levels, short implants appear to perform better in the mid-term (up to 5 years) than standard dental implants associated with vertical bone augmentation regarding MBL and BC, but they have a similar performance regarding IS rates and PC. There is an imperative need to improve the methodological quality of SRs, and efforts should focus on conducting RCTs to broaden the knowledge on this topic. CLINICAL RELEVANCE: Short implants could represent a viable, simpler, and less invasive treatment when available bone height is limited.

Failures in Single Extra-Short Implants (≤ 6 mm): A Systematic Review and Meta-analysis.

PURPOSE: The aim of this systematic review with meta-analysis was to compare the survival rate of single crowns supported by extra-short implants (≤ 6 mm) to those supported by conventional implants, with or without previous maxillary sinus augmentation. The proportion of failures was described according to the type of complication and follow-up periods. MATERIALS AND METHODS: Randomized and prospective clinical trials were selected from six databases and gray literature. The risk of bias was evaluated by Joanna Briggs Institute Critical Appraisal Checklist, and the certainty of the evidence was analyzed with Grading of Recommendations Assessment, Development, and Evaluation. Meta-analyses were processed with RevMan and MedCalc Statistical Software. RESULTS: Single crowns supported by extra-short implants had a similar risk of failure to those supported by conventional implants, regardless of previous maxillary sinus augmentation (P > .05). Overall failure proportion of extra-short implants was 5.19%, but it varied according to follow-up (1.18% before loading, 1.56% at 12 months, 1.20% at 24 months, 2.10% at 48 months). Biologic failure complications were 37.90% for bleeding on probing, 22.45% for peri-implantitis, and 11.29% for infection. Prosthodontics failure complications were 14.88% for abutment failures and 14.73% for prosthetic screw loosening. Considering the risk of bias, most studies were classified at moderate risk. CONCLUSION: The risk of failure of single crowns supported by extra-short implants is similar to those supported by conventional implants, regardless of previous maxillary sinus augmentation or follow-up period. The most frequent biologic and prosthetic complications were bleeding on probing and abutment failures, respectively.

Prevalence of orofacial injuries in wheeled non-motor sports athletes: A systematic review and meta-analysis.

BACKGROUND/AIMS: As the popularity of sports activities grows, so do the number of sport-related injuries. Furthermore, sports that use equipment or vehicles that modify the speed of the player can present more serious injuries. The aim of this systematic review was to identify the overall prevalence of orofacial trauma in wheeled non-motor sports athletes. METHODS: The search strategy was applied in eight electronic databases (Embase, LILACS, Livivo, PEDro, PubMed, Scopus, SportDiscus, and Web of Science). Additionally, a complementary search of the gray literature (Google Scholar, OpenGrey, and ProQuest Dissertations & Theses Global), reference lists of included articles, and studies indicated by experts on the subject was done. The included articles were observational studies with sufficient data of orofacial trauma (type and anatomical site) in wheeled non-motor sport athletes, regardless of the competition level. Risk of bias was assessed by using the Joanna Briggs Institute Critical Appraisal Checklist for Studies Reporting Prevalence Data. The meta-analysis was performed using R Statistics software, and the strength of cumulative evidence was assessed by The Grading of Recommendations Assessment, Development, and Evaluation. RESULTS: From 4042 identified studies, after the removal of duplicates and phase one of selection (title and abstracts screening), 251 studies remained for phase two (full-text screening). Five articles were finally included. One study was considered to have a low risk of bias and four had a moderate risk of bias. The cumulative prevalence of orofacial injuries in wheeled non-motor sport athletes was 21.7% (CI: 8.7-34.7; I2 :97.6%) and the prevalence of dental injuries in these sports was 7.5% (CI:4.3-10.7; I2 :61.9%). The certainty in cumulative evidence was considered to be very low. CONCLUSION: About 22% of the wheeled non-motor sport athletes have suffered orofacial injuries. The most prevalent type of injury was classified as dental trauma.

Association between obstructive sleep apnea and health-related quality of life in untreated adults: a systematic review.

PURPOSE: The objective of this systematic review was to answer the question: "Is there association between obstructive sleep apnea (OSA) and health-related quality of life (HRQoL) in untreated adults?" METHODS: We included observational studies that evaluated the health-related quality of life of patients with OSA vs control groups, through generic and disease-specific questionnaires. The searches were conducted in six databases: Embase, Lilacs, PsycINFO, PubMed, Scopus, and Web of Science. Additional search in the grey literature and hand search were performed, and also experts were consulted. Risk of bias was performed by using Joanna Briggs Institute Critical Appraisal Checklist for cross-sectional, cohort, and case-control studies. We analyzed the data using a narrative synthesis. The Grading of Recommendations Assessment, Development, and Evaluation evidence profile was used to verify the overall certainty of the assessed evidence. RESULTS: Nineteen studies were included for qualitative analysis. Generic questionnaires showed worse HRQoL in the OSA group compared to the control group in at least one domain of the HRQoL questionnaires. The affected domains that showed statistical and clinically relevant differences were physical functioning, physical role, pain, general health, vitality, emotional role, and mental health. The certainty of evidence assessment was very low. CONCLUSION: The available literature suggests that OSA in untreated adults is associated with worse HRQoL. However, this association seems to disappear when we consider only studies adjusted for related covariates. REGISTRATION: CRD42018114746.

Effect of cyanoacrylate tissue adhesive in postoperative palatal pain management: a systematic review.

OBJECTIVE: To critically appraise available literature concerning the effect of cyanoacrylate tissue adhesive (CTA) in postoperative palatal pain management. MATERIALS AND METHODS: Electronic databases (Cochrane, PubMed, LILACS, Scopus, and Web of Science) were searched, complemented with grey literature databases up to June 2020. Studies reporting the effect of cyanoacrylate tissue adhesive compared to any other methods in postoperative palatal pain management were considered eligible. The risk of bias among and across included studies was assessed. RESULTS: Finally, four studies were considered eligible. Regarding free gingival graft (FGG), cyanoacrylate tissue adhesive with hemostatic sponge promoted less postoperative pain (PP) and analgesic consumption (AC). Also, cyanoacrylate tissue adhesive with platelet-rich fibrin produced less PP and more wound healing at the palatal area than cyanoacrylate tissue adhesive and wet gauze. Additionally, cyanoacrylate tissue adhesive promoted less PP and AC than wet gauze and suture. Concerning connective tissue graft (CTG), cyanoacrylate tissue adhesive, and suture produced similar PP, AC, and willingness for retreatment. CONCLUSIONS: Based on the low certainty level, cyanoacrylate tissue adhesive appears to promote less PP and AC than wet gauze and suture regarding FGG. Additionally, cyanoacrylate tissue adhesive appears to increase the effect of hemostatic sponge, contributing to the reduction of PP and AC. Regarding CTG, cyanoacrylate tissue adhesive appears to promote similar PP, AC, and willingness for retreatment than the suture. Therefore, cyanoacrylate tissue adhesive has shown promising usefulness for PP management in FGG, but not a clear benefit for CTG. CLINICAL RELEVANCE: The adoption of different agents for the protection of the palatal donor site following gingival harvesting procedures may provide better comfort to the patient.

Association Between Sleep Bruxism and Quality of Life: A Systematic Review.

AIMS: To evaluate the association between sleep bruxism (SB) and quality of life (QoL) in the general population. METHODS: A systematic review was conducted, and studies were included with no restrictions regarding age, gender, or language. SB and general health-related QoL and/or oral health-related QoL (OHRQoL) measures in the included studies needed to be based on validated tools. The databases searched were Google Scholar, LILACS, OpenGrey, ProQuest, PubMed, Science Direct, Scopus, and Web of Science. Quality of evidence was evaluated using the Joanna Briggs Institute critical appraisal checklists and GRADE (Grading of Recommendations Assessment, Development, and Evaluation) criteria. RESULTS: Fourteen studies met the inclusion criteria. Ten studies were published in English, and four in Portuguese. All studies evaluating the association of SB with health-related QoL showed no statistical significance when overall scores were considered. The overall quality of evidence was considered very low due to high heterogeneity among the studies. SB seemed not to be associated with health-related QoL, but did have a negative impact on some characteristics of OHRQoL. CONCLUSION: There is insufficient scientific evidence to support or disprove the association between SB and QoL/OHRQoL in the general population.
