Association between sex of the individual with untreated cleft lip and social judgement made by lay persons: A cross-sectional study.

OBJECTIVE: To assess whether there is an association between an individual's sex and social judgements made by lay persons regarding untreated cleft lip. MATERIALS AND METHODS: Lay individuals over 18 years old were recruited through an application to respond online to two questionnaires: a sociodemographic survey and the Brazilian Version of Lay Persons' Social Judgements about Cleft-lip Scale (B-LSojCleft-S). B-LSojCleft-S comprises 14 items evaluating social judgements made by laypersons concerning different types of untreated cleft lips in teenagers. The 14 items are linked to 8 images featuring untreated cleft lips and 1 image without a cleft (control). Higher scores represented more favourable social judgements. Independent samples t-test, paired, and multiple linear regression were conducted (P < 0.05). The study assessed judgements of untreated cleft lips in male and female adolescents using the B-LSojCleft-S. RESULTS: The mean age of the 217 participants was 37.78 ± 12.39 years, predominantly women (72.7%), married (47.7%), with a monthly income below three minimum wages (35.6%) in the majority of cases. Significantly higher social judgement scores were observed in the control group (no cleft) compared to any type of cleft (P < 0.001), with similar scores obtained for the same types of clefts with female or male images (P > 0.05). The participant's sex is associated with social judgement scores (F [1, 214] = 6.318, P = 0.013; adjusted R2 = 0.024), with females making more favourable judgements than males (P < 0.05). CONCLUSIONS: Individuals with cleft lips receive more negative social judgement scores, regardless of their own sex. Women make better social judgements than men.

Development and psychometric properties of a questionnaire about knowledge of lay people about traumatic dental injury.

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.

World trends in publication for maxillofacial and dental trauma in the elderly.

Aging may increase the risk of maxillofacial and dentoalveolar trauma (MDT). This review assessed global trends in scientific publications on MDT in the elderly. Six databases were searched. Studies about MDT in the elderly (≥60 years old) were included in two text mining stages (S1 and S2). In S1, all studies with elderly subjects were included, while in S2 only studies in which the elderly were assessed in a separate set of data or in a subanalysis by age groups were included. In S1, relevant data were mined using VantagePoint™ software. In S2, data were descriptively analyzed. There were 2265 studies at S1 and 110 at S2. The publication dates spanned from 1963 to 2023. In S1, the most cited keywords and terms were aged (n = 1872), male (n = 1839), female (n = 1777), "mandible fracture" (n = 460), "orbit fracture" (n = 362), and "maxilla fracture" (n = 118). Thirty authors published 10 or more articles with visible collaboration networks. There was a progressive increase in publications, especially in Europe (n = 150). In S2, most studies were case reports/case series (n = 62). The primary etiology was accidental falls (n = 84), the most affected region was the middle third of the face (n = 65), and dental trauma was rarely reported (n = 15). Cone Beam computed tomography was the most used diagnostic tool (n = 67). Of the 81 articles that addressed therapy, 52 opted for surgical treatment. Although there has been an increase in the number of articles on MDT over the years, studies with the elderly population as a specific study group are still needed. Accidental falls were the most reported etiology, while the middle third of the face and the mandible were the anatomic region and bone most affected, respectively. The high number of case reports indicates the need for improvement in the available scientific evidence about MDT in the elderly.

Did the Use of Minimum Interventions for Caries Management Change during the COVID-19 Pandemic? A Cross-Sectional Study.

The aim of this study was to evaluate changes in the frequency of use of minimum intervention (MI) techniques for caries management during the COVID-19 pandemic. A questionnaire was applied through the SurveyMonkeyTM platform to evaluate changes in the dentist's frequency of use of noninvasive, microinvasive, minimally invasive, and mixed interventions, nonaerosol or aerosol productive, to manage dental caries before and during COVID-19 pandemic. Differences in the use of MI techniques were analyzed by Wilcoxon test, and the effect size (ES) was calculated. An α = 0.05 was adopted. A total of 781 dentists answered the questionnaire; most of them were female (76.4%), with 30s (76.4%), graduated over 10-24 years ago (38%) in public dental schools (62%), graduated in southwest of Brazil (38%), that work in clinical environment (66.8%) and in private jobs (53.4%). During COVID-19, among the sample, 91 respondents were not working. In relation to the noninvasive techniques, only the use of casein phosphopeptide amorphous calcium phosphate (CPP-ACP) decreased during the COVID-19 pandemic (p < 0.01; ES = 0.11). The frequency of sealants to repair defective restorations was the only microinvasive technique that increased during the pandemic (p < 0.01; ES = 0.03). Among the minimally invasive techniques, the use of atraumatic restorative treatment increased significantly (p < 0.01; ES = 0.06), while the use of air abrasion decreased (p = 0.02; ES = 0.04) during COVID-19 pandemic. Moreover, nonrestorative cavity control (mixed intervention) increased during pandemic period (p < 0.001; ES = 0.11). Although the results demonstrated differences in the use of some procedures, a very small magnitude of the effect was perceived, demonstrating that the influence of COVID-19 pandemic was very little, if any, in the use of MI techniques for caries management. Moreover, the use of MI strategies was already well established between Brazilian dentists before the pandemic period.

Global prevalence of human papillomavirus-related oral and oropharyngeal squamous cell carcinomas: a systematic review and meta-analysis.

OBJECTIVE: To conduct a systematic review to determine the global prevalence of HPV in oral squamous cell carcinoma (OSCC) and oropharyngeal squamous cell carcinoma (OPSCC). MATERIALS AND METHODS: Literature was searched through October 2022 in main databases to address the question "What is the global prevalence of Human Papillomavirus in oral and oropharyngeal cancer?" Studies had to identify HPV by PCR, ISH, or p16 immunohistochemistry to be eligible. Quality was assessed using the JBI checklist for prevalence studies. Meta-analyses were performed, and reporting followed PRISMA guidelines. RESULTS: Sixty-five studies were included, and most of them had methodological limitations related to sampling and the HPV detection tool. The pooled prevalence of HPV-positivity was 10% (event rate = 0.1; 95% CI: 0.07, 0.13; P < 0.01; I2 = 88%) in the oral cavity and 42% (event rate = 0.42; 95% CI: 0.36, 0.49; P = 0.02; I2 = 97%) in oropharynx. The highest HPV prevalence in OSCC was reached by Japan, meanwhile, in OPSCC, Finland and Sweden were the most prevalent. HPV16 is the genotype most frequent with 69% in OSCC and 89% in OPSCC, being the tonsils the intraoral location more affected by HPV (63%, p < 0.01, I2 76%). CONCLUSION: The evidence points to an apparent burden in HPV-related OPSCC, mostly in North America, Northern Europe, and Oceania, especially due to the HPV16 infection suggesting different trends across continents. CLINICAL RELEVANCE: This updated systematic review and meta-analysis provide sufficient evidence about the global HPV prevalence in OSCC and OPSCC and the most frequent HPV subtype worldwide.

Patient perception of orthodontists with different stereotypes: development, psychometric properties, and application of an assessment instrument.

INTRODUCTION: This research aimed to develop and validate a questionnaire that considers social judgments and, through its application, assesses whether the presence of piercings, tattoos, beards, and loose hair visible in the face and neck region reflect on the patient perception regarding characteristics of the orthodontist's professional scope. METHODS: The developed questionnaire had its psychometric properties evaluated and was applied to 220 young people and adults, aged 18-70 years, who responded according to their perception of 12 manipulated images of orthodontists with different stereotypes, considering the following items: hygiene, care, punctuality, experience and knowledge in orthodontics. RESULTS: The developed questionnaire showed high acceptability, confirmed reliability and validity of the construct, and satisfactory internal consistency. The stereotype interfered with the perception of professionalism (P <0.01), in which the orthodontist with combined characteristics (beard/loose hair, piercing, earrings, and tattoo) obtained the lowest mean scores, both for each item of the questionnaire individually (P <0.01) and in total (P <0.01). Health professional (P = 0.427) and educational level (P = 0.285) status did not influence the perception; however, there was a significant difference for the age groups (P = 0.041). CONCLUSIONS: The developed questionnaire proved to be valid and reliable for application. Orthodontists with piercings and tattoos on the face and neck were considered less professional. Being a health professional and educational level status did not influence the perception. However, older subjects (aged 51-70 years) were more critical in judging stereotypes than younger subjects (aged 18-30 years).

Critical appraisal of the information available on traumatic dental injuries found in applications.

BACKGROUND/AIMS: Traumatic dental injuries (TDI) are a public health problem and the search for information becomes essential to help in their management. The aim of this study was to search existing TDI applications (Apps) to critically describe the characteristics and main information found in them regarding TDI. METHODOLOGY: Searches were performed in the Play Store (Android) and App Store (iOS), using MeSH terms, synonyms and terms related to dental emergencies and TDI, in English, Spanish and Portuguese. Apps with information on the management of post-TDI emergencies or TDI prevention were included. The type of operating system (Android/iOS), cost (free/paid), target audience (dentist/patient), age of classification (free/>17 years old), language, star rating (1★ to 5★), number of downloads and post-download ratings, type of dentition (primary/permanent), reference used for classification according to TDI type and management (International Association for Dental Traumatology/Andreasen/others/not reported), and available content (prevention/emergency management/preservation/illustrations) were evaluated. RESULTS: Among 486 apps, 13 were eligible: 11 for Android and 2 for iOS. Most were free (92.3%), for patients (38.4%) and had a free age classification (90.9%). The main language was English (53.8%), and most of the Apps either had no information on star ratings (46.1%) or received 4★ (23.1%). The number of downloads was not reported (23.1%) or was fewer than 100 (23.1%). Most of the Apps were for permanent teeth (61.5%) and had explanations about dental management for TDI emergencies (92.3%) and multiple TDIs (61.5%). Most Apps addressed the importance of monitoring TDIs (76.9%) and contained illustrative images (76.9%). However, many did not report the TDI classification (46.1%), and 38.5% reported TDI prevention. CONCLUSIONS: Information on dental trauma management according to dental injury, inclusion of images, target audience, type of TDI and their prevention varied in the available Apps. However, most were focused on permanent teeth and addressed several TDI in English language only.

A world panorama of bruxism in children and adolescents with emphasis on associated sleep features: A bibliometric analysis.

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.

Impact of crown fracture treatment on oral health-related quality of life of children, adolescents, and their families: A prospective clinical study.

BACKGROUND: Enamel-dentin fracture causes impact on the oral health-related quality of life (OHRQoL) of children. AIM: To evaluate the impact of treatment of crown fracture involving enamel and dentin (CFED) in the permanent dentition on the OHRQoL of children and adolescents (C/As) and their families. DESIGN: This prospective clinical study included C/As between 8 and 14 years who presented anterior CFED treated thought direct composite resin restoration. Their parents/caregivers (P/Cs) were also invited to take part of the study. The quality of life was evaluated thought the Child Perceptions Questionnaires (CPQ8-10  and CPQ11-14 ), Parental-Caregiver Perceptions Questionnaire (P-CPQ), and Familiar Impact Scale (FIS), applied before and 3 months after the restorative procedure. T test for dependent samples and Wilcoxon test were applied(P < 0.05). RESULTS: Of 32 C/As included, 30 completed the study. The treatment of CFED reduced the negative impact in OHRQoL of C/As (CPQ8-10 P = 0.0065; CPQ11-14 P = 0.0486; P-CPQ, P = 0.0259), specially for "oral symptoms" (CPQ8-10 , P = 0.0003; P-CPQ, P = 0.0455) and "emotional well-being" (CPQ11-14 , P = 0.0431). Concerning the families' perceptions, the treatment did not influence OHRQoL both in terms of the domains and total FIS score (P > 0.05). CONCLUSION: Restorative treatment of CFED increases the OHRQoL of C/As but not influence the OHRQoL of their families.

Does dental trauma influence the social judgment and motivation to seek dental treatment by children and adolescents? Development, validation, and application of an instrument for the evaluation of traumatic dental injuries and their consequences.

BACKGROUND: One's smile clearly plays a significant role in the perception and judgment that others have of one's appearance and personality. AIM: We sought to develop and validate a questionnaire related to the social judgment of children and adolescents and to evaluate, through its application, the perceptions and judgment of children and adolescents regarding their view of different traumatic dental injuries and their consequences (TDIs-Cs) as well as the motivation to seek dental treatment. DESIGN: The aspects of acceptability, discriminative properties, internal consistency, test-retest reliability, and construct validity were evaluated in the developed questionnaire. A cross-sectional study was conducted involving 100 boys and girls aged 10-15 years. Images of an adolescent male and female were either manipulated or not (control) to create different types of TDI-C (eg, enamel fracture, enamel and dentin fracture, crown colour change, and tooth loss/avulsion). These images were analysed by the participants, using a previously validated questionnaire with a six-positive-point and six-negative-point scale, in relation to their social physical and psychosocial characteristics. The data were analysed with the Friedman, Wilcoxon, and Mann-Whitney tests (P < 0.05). RESULTS: The developed questionnaire presented high acceptability, strong discriminative properties, satisfactory internal consistency, and satisfactory test-retest reliability, but weak construct validity. The presence of TDI-C had a negative effect on all characteristics evaluated (P < 0.001). Tooth loss had the highest level of rejection. Additionally, the presence of TDI-C had a greater negative impact on the aspects of 'starting fights', 'being given a nickname', and 'being ashamed to smile' in males than in females (P < 0.05). Children and adolescents with TDI-C were judged as needing to seek dental treatment (P < 0.001). CONCLUSION: The questionnaire developed showed properties of validity and reliability in its administration in a child and adolescent population. TDIs-Cs have a negative influence on the social judgment of children and adolescents.

Risk factors for traumatic dental injuries in the Brazilian population: A critical review.

BACKGROUND/AIMS: Strategies for the prevention of traumatic dental injuries (TDI) should consider the risk factors involved for each population studied. The aim of this study was to perform a critical review regarding the risk factors for TDI in the Brazilian population. MATERIALS AND METHODS: A systematic literature search was performed in the MEDLINE, Scopus, Web of Science, Lilacs, and BBO databases using MeSH terms, synonyms, and keywords, with no language or date restrictions. In the first step, all relevant studies identified, regardless of the type of statistical analysis performed, were grouped according to their geographic location. In a second step, the studies using Andreasen's criteria to classify the injuries and multivariate analysis to identify the risk factors for TDI in Brazilian subjects were included for data extraction. RESULTS: The search strategy initially identified 3373 articles. However, only 108 articles assessed TDI with predisposing factors and were included in the first step. From those, 28 were deemed eligible for inclusion in the second step. No consensus related to the relationship between gender and TDI in the primary dentition was achieved. Nonetheless, males were found to be more prone to trauma in the permanent dentition. Overjet, inadequate lip sealing and anterior open bite increased the risk for TDI, both in primary and permanent dentitions. Social environment was related to trauma only in primary dentition. For permanent dentition, dental caries, obesity, binge drinking, and drug use were identified as considerable risk factors for TDI. CONCLUSION: The risk factors for TDI in the Brazilian population are similar to those found worldwide. However, some differences can be observed, such as gender and socioeconomic indicators as predisposing factors.

Lesions in the oral mucosa associated with the use of checkpoint inhibitors: A bibliometric and critical review.

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.

Development and validation of the Brazilian Version of Lay Persons' Social Judgements about Cleft-lip Scale (B-LSojCleft-S).

The aim of this study was to develop and analyze the psychometric properties of the Brazilian Version of Lay Person's Social Judgement about Cleft-lip Scale (B-LSojCleft-S). A standardized photograph of a 16-year-old girl was manipulated by using photo editing software, to simulate different cleft-lip situations. The cleft-free image was used as a control. The researchers structured an initial questionnaire that was evaluated by experts and a sample of the target population to evaluate the construct. After analysis by the researchers, a final version of the B-LSojCleft-S containing 14 items was generated. Each answer was awarded score from 1 to 3 points, yielding a total score of 14 to 42 points. Higher scores represented better social judgements. The B-LSojCleft-S was applied online to 103 test participants and 73 retest participants with an interval of 20 days between application. Aspects of acceptability, discriminant property, internal consistency, reliability and construct validity were evaluated. Construct validity was assessed using the Friedman test (p < 0.05). Reliability was determined using an intraclass correlation coefficient > 0.70, and internal consistency using Cronbach's alpha > 0.81. The B-LSojCleft-S showed high acceptability, strong discriminant property, excellent internal consistency and reliability, but had a floor and ceiling effect. The instrument reached valid and reliable scores and had acceptable psychometric properties to evaluate the social judgments of lay persons about different cleft lip situations in a Brazilian population.

Development, validation, and application of a Brazilian sleep myths and truths assessment scale (SLEEP-MTAS).

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.

Emoji as promising tools for emotional evaluation in orthodontics.

BACKGROUND: Emoji are pictograms frequently used in social networks capable of expressing emotions. These tools can provide insights into people's behavior that could not be obtained with the use of textual communication. Recently, emoji have been introduced to various research fields as successful alternatives to word-based questionnaires for measure emotional responses. The objective of this study was to preliminarily evaluate the discriminating ability and relationship of these tools with different occlusal conditions/malocclusions. METHODS: Online surveys were applied to adult individuals (n = 201; mean age = 27.4 ± 5.7; 37.3% males, 62.7% females). Subjects issued acceptance scores (10-point scale) and expressed their emotional status using a 30-emoji list in relation to nine occlusal conditions: C1-crowding, C2-anterior open bite, C3-interincisal diastema, C4-increased overjet + deep bite (Class II div. 1), C5-anterior crossbite (Class III), C6-ideal occlusion, C7-unilateral posterior crossbite, C8-anterior open bite plus bilateral posterior crossbite plus crowding, and C9-deep bite (Class II div. 2). Cochran's Q and McNemar tests were used to compare the frequencies of choice of emoji between conditions. Correspondence analyses were applied to assess the association between occlusal conditions and emoji. Kendall's correlation coefficient was calculated to evaluate the relationship between mean acceptance scores and frequency counts of each emoji. RESULTS: The frequency of choice between conditions showed a significant difference for 25 of the 30 emoji (P < 0.05), indicating an adequate discriminating ability of these tools. Emoji were grouped predominantly based on their emotional valence (positive/negative) and arousal/activation (high/low). Positive emoji were associated with the most accepted conditions (i.e., C6, C3), while negative emoji with the most rejected ones (i.e., C8, C1, C2). Although only weak, positive correlations between acceptance and positively valenced emoji, and negative correlations between acceptance and negatively valenced emoji were observed (P < 0.05). CONCLUSIONS: Emoji have an adequate discriminatory ability and would allow determining emotional profiles in the face of different occlusal conditions. Further research is necessary to consolidate the use of these tools in an instrument that allows measuring emotional responses.

Development, validation and application of a Brazilian knowledge scale about sports doping in dentistry.

To evaluate the knowledge of Brazilian dentists of sports doping through the development, validation and application of the Brazilian Knowledge Scale about Sports Doping in Dentistry (B-KSSDD). A scale with 12 items was developed to assess a dentist's ability to determine whether the use of a medication characterised sports doping according to the World Anti-Doping Agency. A preliminary study to validate the B-KSSDD was carried out with 135 dentists, allowing the evaluation of ceiling and floor effects, convergent and discriminant validity, test-retest reliability and internal consistency of the instrument. A sample size calculation using the results of the preliminary study and the B-KSSDD was completed online using SurveyMonkey® by 270 participants from all regions of the country. The B-KSSDD showed evidence of convergent and discriminant validity, good temporal stability (ICC = 0.75) and internal consistency (alpha = 0.89). In the main study, the participants obtained an average score of 4.19/12 points on the B-KSSDD, suggesting that these professionals have insufficient knowledge about sports doping. The age of participants showed a negative association with knowledge about doping, while frequency of treating athletes and frequency of performing surgeries showed positive associations with knowledge about doping. The dentists had insufficient knowledge of the subject. Age of participants and frequency with which they attend to athletes are associated with knowledge about sports doping. Professional updating and education policies on doping are necessary for dentists, as athlete patients are at risk for severe sporting and financial penalties.

Factors associated with depression, anxiety and stress among dentists during the COVID-19 pandemic.

The objective of this work was to evaluate the relationship between factors associated with the COVID-19 pandemic and depression, anxiety, and stress (DAS) in dentists. Factors associated with the COVID-19 pandemic were evaluated using a questionnaire and scores of the Depression, Anxiety, and Stress Scales-21 were measured. The differences between the DAS scores based on the factors associated with the COVID-19 pandemic were tested through the successive application of multivariate analysis of variance (MANOVA, α = 0.05). After a sample size calculation, 998 participants with a mean age of 39.39 (± 11.69) years were included. The effect size indicated that changes in sleep quality (η2 = 0.161), eating habits (η2 = 0.057), and physical health (η2 = 0.051) were the ones that most negatively affected DAS scores. The highest DAS scores were observed in professionals who lived with someone at high-risk for COVID-19 (p < 0.001) and in those who did not engage in leisure activities during the pandemic (p < 0.001). Dentists who worked on the frontline against COVID-19 had higher scores of anxiety and stress (p = 0.029). The highest scores for anxiety, depression, and/or stress were seen in dentists living with someone at high-risk for COVID-19, who acts on the frontline, who does not practice in leisure activities during the pandemic, who completely changed eating habits, quality of sleep and physical health during the pandemic. In general, DAS levels of dentists were associated with factors related to the COVID-19 pandemic.

Clinical Findings Arising from the Use of Silver Diamine Fluoride to Prevent or Treat Caries Lesions and Dentinal Hypersensitivity: A Data Mining Analysis

Abstract Objective: To summarize data of clinical trials that used silver diamine fluoride (SDF) to prevent and treat caries lesions and dentinal hypersensitivity. Material and Methods: Six electronic databases were searched in May 2022. The concentration of SDF, type of usage (alone/combined), dentition, anterior/posterior teeth, tooth region, dental tissue, number of the treated surfaces, the intervention environment, participants' age, frequency and duration of SDF application, purpose, and outcome were the extracted variables. The type of study, year of publication, authors, journals, and country were also investigated. Results: From 8860 articles, S3 were selected. Most were randomized (n=38), that applied 38% SDF (n=43), alone (n=44), on multiple surfaces (n=44), only in dentin (n=36), of the crown (n=46) of anterior and posterior (n=36) primary teeth (n=39). The studies were preferably carried out outside the clinic (n=3l), only in children (n=33), with reapplication of SDF (n=30), but did not inform the duration of application (n= 19). SDF was most used to treat (n=46) only caries lesions (n=50). They were published between 2001 and 2022, mainly in the Journal of Dentistry (n=10). China (n=19) and Lo E.GM (n=19) were the countries and authors that published the most, respectively. Conclusion: The silver diamine fluoride 38% alone was most used to treat caries lesions in the dentin of the crown of all primary teeth, preferably applied on multiple surfaces, requiring re application, and outside the clinic.
