Abstract 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.

ABSTRACT Objective: To evaluate the presence of sequelae in primary teeth and their permanent successors, as well as associations between TDI and the presence of sequelae in both teeth. Material and Methods: In this 14-year retrospective study, 2.290 records were reviewed, 192 patients who suffered dental trauma in primary teeth were followed until the eruption of successor teeth were included. Descriptive, chi-square, and regression logistic with generalized estimating equations tests were performed (p<0.05). Results: 362 primary and successor teeth were followed. Sequelae were present in 71.8% of primary teeth and 25.7% of their successors. Teeth with complicated fracture (100%), extrusion (100%) and avulsion (100%) resulted in the largest amounts of sequelae in primary teeth and intrusion (61%) on their successors. Age was associated with sequelae in permanent teeth (p<0.01). Extrusion (OR 10.06; CI 2.12-47.63) and intrusion (OR 7.51; CI 2.73-20.70) had a higher risk to cause sequelae in primary and permanent teeth, respectively. Conclusion: The type of injury involved influenced the sequelae in traumatized teeth and their successors, and the age of the child influenced the presence of sequelae in permanent teeth.

Abstract 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.

Abstract 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.

Abstract Objective: To evaluate traumatic dental injuries (TDI) in primary teeth and the association of gender and age with different injuries. Material and Methods: Records of patients with TDI in primary teeth were included. The following parameters were registered: gender and age, place of trauma, cause of trauma, affected tissue and tooth, number of injured teeth, type of injury, and gingival and bone damage. A logistic regression analysis was performed to explore the interaction between gender and age on the occurrence of types of injuries (p≤0.05). Results: The total of 721 records were evaluated and 370 records were included, being 61.6% boys and 60.5% children aged 0-3 years old, with 658 primary teeth affected. The support tissue was most affected (496/658), followed by dental tissue (139/658). Enamel/dentine fracture with pulp exposure (n=51) and intrusion (n=131) were the most common injuries of dental and support tissues, respectively. In general, boys suffered more traumas than girls, regardless of the age range. As for concussion, logistic regression confirms that gender and age are also influencers. Girls (OR=1.822, CI = 1.050-3.164, p=0.033) in the 4-6 year age group (OR=2.15, CI = 1.239-3.747, p=0.007) are more likely to have concussions. Children age 4-6 years were less likely to suffer an intrusion (OR=0.496; CI = 0.278-0.886; p=0.018). Conclusion: Gender and age influence concussion and intrusion in the primary teeth.

Abstract Objective: To evaluate the influence of cavosurface vestibular bevel (CSVB) application on the clinical success (CS) of class IV restorations of traumatized permanent teeth, the influence of the number of fracture angles and dental trauma recurrence (DTR) on the restorations retention rate (RRR) and incidence of pulp necrosis (PN). Material and Methods: Fifty-seven children and adolescents with enamel and dentin fractures requiring C-IV restorations were randomly allocated in groups with CSVB and without CSVB. The primary outcomes were the CS of restorations, evaluated using modified USPHS criteria, and the incidence of PN after a 6-months follow-up. As secondary outcomes, the influence of the number of fractured angles and the DTR on the RRR and on the incidence of PN were evaluated (p>0.05). Results: Of 57 children and adolescents, 74 teeth were restored, and 71 completed the six-month follow-up analysis. Teeth restored with and without CSVB displayed similar CS as well as the same incidence of PN (p>0.05). The number of fractured angles did not influence the RRR and DTR was not associated with PN (p>0.05). DTR was associated with a lower RRR (p<0.001). Conclusion: Cavosurface vestibular bevel did not influence the clinical success of Class IV restorations or incidence of PN after 6-months follow-up. DTR did not influence the incidence of pulp necrosis, but did negatively influence the restorations retention rate. The number of fracture angles did not influenced in the restorations retention rate.
