Aesthetic perception of black spaces between lower incisors by laypeople of different ethnicities and age groups

Objective: To evaluate the degree of perception among lay people of different age groups about black spaces between lower incisors. Methodology: digital changes were performed in a frontal photograph of a smiling 30 year-old patient, simulating different dimensions of black spaces. The images were printed on photographic paper and applied with a questionnaire in order to evaluate the attractiveness using as tool a visual analogue scale (VAS). The participants were divided into 6 groups, considering race (Caucasian and Negroid) and age (15-19 years, 35-44 years and 65-74 years old). The differences between the examiners were checked by the Mann-Whitney test and the significance level was 5% (α = 0.05) for all analyzes. Results: The photographs that did not have black spaces were better graded and the ones that had larger black spaces scored worse. The older age group and the Negroid race group graded better the photograph with the largest black spaces, compared to the younger age groups and the group of Caucasians. Conclusion: black spaces between lower incisors are esthetically unattractive and their perception decreases with aging, besides being less relevant to older and Negroid people.

Parâmetros espirométricos podem predizer a incidência de fragilidade em pessoas idosas? / Can spirometric parameters predict the incidence of frailty in the elderly people?

Objetivo: Verificar a associação entre indicadores espirométricos e a incidência da síndrome de fragilidade em pessoas idosas. Métodos: Trata-se de um estudo com delineamento longitudinal realizado em 2014-2019, com uma amostra de estudo de 104 pessoas idosas. A variável dependente foi a síndrome de fragilidade, avaliada por meio do fenótipo de Fried et al. e as variáveis independentes foram os indicadores espirométricos, sendo eles a Capacidade Vital Forçada (CVF), Pico de Fluxo Expiratório (PFE), Volume Expiratório Forçado no primeiro segundo (VEF1), relação VEF1/CVF e o Fluxo Expiratório Forçado 25%-75% (FEF25-75%). Resultados: A incidência de pessoas idosas frágeis foi de 16,3% em ambos os sexos, sendo que o sexo masculino apresentou melhores indicadores de função pulmonar que as mulheres. Apesar disso, observamos que não houve associação entre a síndrome de fragilidade e os indicadores espirométricos (p>0,05). Conclusão: Os indicadores espirométricos não são preditores de fragilidade em pessoas idosas residentes na comunidade, após cinco anos de seguimento.

Objective: To verify the association between spirometric indicators and the incidence of frailty syndrome in elderly people. Methods: This is a study with a longitudinal design carried out in 2014-2019, with a study sample of 104 elderly people. The dependent variable was the frailty syndrome, assessed using the phenotype of Fried et al. and the independent variables were the spirometric indicators, namely Forced Vital Capacity (FVC), Peak Expiratory Flow (PEF), Forced Expiratory Volume in one second (FEV1), FEV1/FVC ratio and Forced Expiratory Flow 25%-75 % (FEF25-75%). Results: The incidence of frail elderly people was 16.3% in both genders, with males presenting better lung function indicators than females. Despite this, we observed that there was no association between the frailty syndrome and the spirometric indicators (p>0.05). Conclusion: Spirometric indicators are not predictors of frailty in community-dwelling elderly people after five years of follow-up.

Alterações dimensionais em marcas de mordidas humanas simuladas em alimentos: estudo in vitro / Dimensional changes in simulated human bite marks on food: in vitro study

Objetivo: avaliar alterações dimensionais em marcas de mordidas simuladas em um tipo de queijo e de goiabada com o decorrer do tempo. Materiais e Métodos: mordidas foram simuladas em 20 amostras-padrão formato retangular nas medidas 30 x 60 mm e espessura de 20 mm de queijo tipo muçarela (n=10) e goiabada (n=10) com a utilização de um manequim odontológico montado em oclusão normal e acoplado à máquina universal de ensaios mecânicos. Amostras foram mantidas em superfície de vidro em ambiente com temperatura e umidade controladas seguida da aferição das distâncias intercaninas das marcas a cada hora com auxílio de paquímetro digital, durante 120 horas de experimentação. A temperatura e umidade mantiveram-se constantes durante todo período. As medidas obtidas foram estatisticamente analisadas por meio dos testes de Friedman, de Wilcoxon, coeficiente de correlação de Spearman e a partir da análise de regressão linear simples. O nível de significância adotado foi de 5%. Resultados: os alimentos testados mantiveram o padrão das medidas lineares nas primeiras quatro horas (p>0,05). Após esse período, ocorreu uma deformação progressiva, levando ao aumento significativo das medidas (p<0,05). Conclusão: a marca de mordida em queijo tipo muçarela e goiabada apresentou-se dimensionalmente estável nas primeiras quatro horas, pós mordida. Após esse período, as marcas já não apresentaram características favoráveis para serem utilizadas como registro para fins de comparação.

Conclusion: the bite mark in mozzarella cheese and guava paste it was dimensionally stable in the first four hours, post-bite. After this period, brands no longer have favorable characteristics to be used as a record for comparison purposes.

Pressão expiratória máxima é boa preditora de incidência da síndrome de fragilidade em homens idosos / Maximum expiratory pressure is a good predictor of the incidence of the frailty syndrome in elderly men

Resumo O objetivo deste artigo é investigar a associação entre a Pressão Inspiratória Máxima (PImáx) e Pressão Expiratória Máxima (PEmáx) com a incidência da síndrome de fragilidade (SF), além de testar a capacidade preditiva da PImáx e PEmáx em discriminar a SF em idosos, de acordo com o sexo. Estudo longitudinal com cinco anos de seguimento (2014-2019), realizado com 104 idosos cadastrados na Estratégia Saúde da Família de um município da Bahia. A incidência da síndrome de fragilidade foi diagnosticada de acordo os critérios propostos por Fried et al., utilizando dados de 2019, após cinco anos de seguimento. A PImáx e PEmáx foram avaliadas conforme recomendações da Sociedade Brasileira de Pneumologia e Tisiologia em 2014 (linha de base). A incidência total da SF foi de 16,3% (IC95%: 9,2-23,6), sendo 13,6% (IC95%: 4,56-22,55) no sexo feminino e 20,0% (IC95%: 7,85-32,15) no sexo masculino. Os valores médios da PImáx e PEmáx foram, respectivamente, 60,8±21,2 cmH2O e 76,7±23,1 cmH2O no sexo feminino, e 79,5±27,0 cmH2Oe 114,7±29,8 cmH2O no sexo masculino. A SF esteve associada à PEmáx em idosos do sexo masculino (RR ajustado: 0,96; IC95%: 0,95-0,98; p-valor: 0,002), indicando que o aumento de 1 cmH2O da PEmáx reduz em 4% o risco de desenvolver a síndrome de fragilidade.

Abstract This article aims to investigate the association between maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) with the incidence of frailty syndrome (FS), in addition to testing the predictive ability of MIP and MEP to discriminate FS in elderly adults, according to sex. It is a longitudinal study with a five-year follow-up period (2014-2019), carried out with 104 elderly adults registered in the Family Health Strategy of a municipality in Bahia. The incidence of frailty syndrome was diagnosed according to criteria proposed by Fried et al., using data from 2019, after a five-year follow-up. The MIP and MEP were evaluated according to the recommendations of the Brazilian Society of Pulmonology and Phthisiology data in 2014 (baseline data). The total incidence of frailty syndrome was 16.3% (95%CI: 9.2-23.6), with 13.6% (95%CI: 4.56-22.55) in women and 20% (95%CI: 7.85-32.15) in men. The mean values of MIP and MEP were, respectively, 60,8±21,2 cmH2O and 76,7±23,1 cmH2O in women, and 79,5±27,0 cmH2O and 114,7±29,8 cmH2O in men. The frailty syndrome was associated with MEP in elderly adult men (adjusted RR: 0.96; 95%CI: 0.95-0.98; P-value: 0.002), indicating that the increase of 1cmH2O in MEP reduces by 4% the risk of developing the syndrome.

The effect of socioeconomic aspects and dental history on pediatric patients' dental anxiety

Abstract This study aimed to characterize the profile of dental anxiety in pediatric patients, identifying the effect exerted by socioeconomic factors using dental data. A cross-sectional study design with a sample of 120 children aged 7-12 years old was used. Data relating to anxiety levels prior to dental care, socioeconomic aspects (family income, education level, child's school type), and child's dental history (previous dental appointments, previous treatment, caries experience) were collected. Additionally, participants completed the Brazilian version of the Children's Fear Survey Schedule- Dental Subscale (B-CFSS-DS) to assess dental anxiety. Descriptive analyses, chi-squared (X 2 ) tests, and Mann-Whitney U tests were performed, with a significance level of 5%. A total of 51 boys (42.5%) and 69 girls (57.5%) were included. There was no significant difference in dental anxiety between them. However, younger children had higher mean B-CFSS-DS scores (p = 0.036, Mann-Whitney). A higher prevalence of dental anxiety was found in participants from low-income families (p = 0.012, X 2 ) and in patients who did not receive endodontic treatment (p=0.034, X 2 ). Higher mean B-CFSS-DS scores were also observed in participants who did not receive endodontic treatment (p=0.001, Mann-Whitney) compared with those that did receive endodontic treatment. No relationship was found between education level, patient school type, first dental appointment, caries experience, and dental anxiety data. Younger children presented a profile of greater dental anxiety. Socioeconomic factors and dental data exerted some effect on dental anxiety, where children from low-income families and those not subjected to endodontic treatment displayed higher rates of dental anxiety.

Are maximum respiratory pressures predictors of sarcopenia in the elderly? / Pressões respiratórias máximas são preditores de sarcopenia em idosos?

ABSTRACT Objective: To compare maximum respiratory pressures and spirometric parameters among elderly individuals classified as having no sarcopenia, probable sarcopenia, and confirmed sarcopenia, and to test the ability of these variables to discriminate sarcopenia in a community-dwelling elderly population. Methods: This was a cross-sectional study involving 221 elderly (≥ 60 years of age) individuals of both sexes. Sarcopenia was diagnosed in accordance with the new consensus of the European Working Group on Sarcopenia in Older People. Maximum respiratory pressures and spirometry parameters were assessed. Results: The prevalences of probable sarcopenia and confirmed sarcopenia were 20.4% and 4.1%, respectively. Regardless of the sex, those with confirmed sarcopenia had significantly lower MEP than those with no sarcopenia and probable sarcopenia, whereas only males with confirmed sarcopenia presented with significantly lower MIP than did the other individuals. There was an inverse association of MIP and MEP with sarcopenia, indicating that the decrease by 1 cmH2O in these parameters increases the chance of sarcopenia by 8% and 7%, respectively. Spirometric parameters were not associated with sarcopenia. Cutoff points for MIP and MEP, respectively, were ≤ 46 cmH2O and ≤ 50 cmH2O for elderly women, whereas they were ≤ 63 cmH2O and ≤ 92 cmH2O for elderly men, and both were identified as predictors of sarcopenia (area under the ROC curve > 0.70). Conclusions: Sarcopenia was associated with lower maximum respiratory pressures, but not with spirometric parameters. Maximum respiratory pressures can be used as markers of sarcopenia in a community-dwelling elderly population regardless of the sex.

RESUMO Objetivo: Comparar as pressões respiratórias máximas e parâmetros espirométricos entre idosos classificados como sem sarcopenia, sarcopenia provável e sarcopenia confirmada e testar a capacidade dessas variáveis de discriminar sarcopenia em idosos residentes em comunidade. Métodos: Estudo transversal envolvendo 221 idosos (≥ 60 anos) de ambos os sexos. Sarcopenia foi diagnosticada de acordo com o novo consenso do Grupo de Trabalho Europeu sobre Sarcopenia em Pessoas Idosas. As pressões respiratórias máximas e parâmetros espirométricos foram avaliados. Resultados: As prevalências de sarcopenia provável e sarcopenia confirmada foram de 20,4% e 4,1%, respectivamente. Independentemente do sexo, aqueles com sarcopenia confirmada apresentaram PEmáx significativamente menor do que aqueles sem sarcopenia e provável sarcopenia, enquanto apenas os homens com sarcopenia confirmada apresentaram PImáx significativamente menor do que os outros indivíduos. Houve uma associação inversa de PImáx e PEmáx com sarcopenia, indicando que a diminuição de 1 cmH2O nesses parâmetros aumenta a chance de sarcopenia em 8% e 7%, respectivamente. Os parâmetros espirométricos não foram associados à sarcopenia. Os pontos de corte para PImáx e PEmáx, respectivamente, foram ≤ 46 cmH2O e ≤ 50 cmH2O para mulheres idosas, enquanto foram ≤ 63 cmH2O e ≤ 92 cmH2O para homens idosos, e ambas foram identificadas como preditores de sarcopenia (ASC ROC > 0,70). Conclusões: A sarcopenia associou-se a pressões respiratórias máximas mais baixas, mas não a parâmetros espirométricos. As pressões respiratórias máximas podem ser usadas como marcadores de sarcopenia em idosos residentes em comunidade, independentemente do sexo.

Physical inactivity and high sedentary behavior are associated with hypertriglyceridemic waist in elderly / Inatividade física e elevado comportamento sedentário estão associados à cintura hipertrigliceridêmica em idosos

During aging, an increase in sedentary behaviour and a decrease in physical activity levels are observed. These factors may increase abdominal adiposity and triglyceride levels, which characterizes the hypertriglyceridemic waist (HW) phenotype, providing a high risk for cardiometabolic diseases. This study aimed to analyze the association between hypertriglyceridemic waist, physical activity level and sedentary behaviour in community-dwelling elderly. A population-based cross-sectional study was carried out, involving 316 elderlies (≥ 60 years) of both genders. The hypertriglyceridemic waist was diagnosed using high triglycerides (≥ 150 mg/dl) and increased waist circumference ≥ 88 and ≥ 102 cm values for women and men, respectively. The physical activity level and sedentary behaviour were evaluated using the IPAQ. The study included 173 women (54.7%) and 143 men (45.3%), with a mean age of 74.2 ± 9.8 years. The prevalence of HW was 27.1%, 47.7% insufficiently active and 24.1% high sedentary behaviour. The insufficiently active elderly (OR= 2.48; 95% CI: 1.31 - 4.71; p= 0.005) and with high sedentary behaviour (OR= 2.21; 95% CI: 1.04 - 4.32; p= 0.038) were associated positively with HW, indicating that elderly with insufficient physical activity levels and high sedentary behaviour showed themselves to approximately 2.5 and 2.2 times more likely to develop HW, respectively. Low physical activity level and high sedentary behaviour are associated with hypertriglyceridemic waist in community-dwelling elderly.(AU)

Durante o envelhecimento, observa-se aumento do comportamento sedentário e diminuições dos níveis de atividade física. Esses fatore podem aumentar a adiposidade abdominal e os níveis de triglicerídeos, o que caracteriza o fenótipo cintura hipertrigliceridêmica (CH), proporcionando um elevado risco para doenças cardiometabólicas. O objetivo deste estudo foi analisar a associação entre cintura hiper- trigliceridêmica, nível de atividade física e comportamento sedentário em idosos. Trata-se de um estudo epidemiológico, com delineamento transversal, de base populacional e domiciliar, realizado com 316 idosos (≥ 60 anos) de ambos os sexos. A cintura hipertrigliceridêmica foi definida a partir dos triglicérideos elevados (≥ 150 mg/dl) e circunferência da cintura alterada (≥ 88 cm para mulheres e ≥ 102 cm para homens). O nível de atividade física e o comportamento sedentário foram avaliados por meio do Questionário Internacional de Atividade Física (IPAQ). Participaram do estudo 173 mulheres (54,7%) e 143 homens (45,3%) com idade média de 74,2 ± 9,8 anos. A prevalência de CH foi 27,1%, 47,7% eram insuficientemente ativos e 24,1% tinham elevado comportamento sedentário. Os idosos insuficientemente ativos (OR= 2,48; IC95%:1,31 - 4,71; p= 0,005) e com elevado comportamento sedentário (OR= 2,21; IC95%:1,04 - 4,32; p= 0,038) foram positivamente associados à CH, indicando que os idosos com níveis de atividade física insuficientes e com elevado comportamento sedentário apresentaram, aproximadamente, 2,5 e 2,2 vezes mais chances de desenvolverem a CH, respectivamente. A inatividade física e o elevado comportamento sedentário estiveram associados à CH em idosos residentes em comunidade.(AU)

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

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.

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

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.

Aesthetic perceptions and social judgments about different enamel opacities

Abstract This study aimed to evaluate adolescents' aesthetic perceptions and their social judgments regarding different enamel opacities. Sample size was calculated and resulted in the inclusion of 100 adolescents (aged 10 to 15 years) from a public school in Jequié, Bahia, Brazil. Images of enamel opacities were manipulated to create aesthetic enamel defects, such as enamel color changes (unilateral and bilateral white opacity, unilateral and bilateral yellowish opacity, and unilateral and bilateral yellowish opacity with loss of structure). The images of the opacities were based on Fédération Dentaire Internationale's Developmental Defects of Enamel (DDE) Index. Aesthetic perception and social judgments were evaluated using a validated questionnaire with 12 questions (six positive and six negative points) on social aspects, considering the six manipulated images and the control. The photographic analyses were projected one-by-one by computer to adolescents individually in a classroom. Participants had one minute to observe each image and answer the questionnaire. The data were analyzed by descriptions, and the Friedman Wilcoxon test (p < 0.05). The results indicate that all opacities negatively impacted social judgment (p < 0.001). The enamel aesthetic defects most affecting an individual's perception were bilateral yellow opacity with or without loss of structure (p < 0.001). Regarding social judgment, all participants showed a negative perception of all the tested opacity types (p < 0.001). In conclusion, even opacities presenting only a color change caused aesthetic dissatisfaction to the individuals and changes in their social judgment toward others. Color changes in dental enamel have several aesthetic consequences.

Does the facial pattern give individuals a profile of a crime suspect? / O padrão facial confere aos indivíduos o perfil suspeito a cometer um crime?

To evaluate the influence of mesofacial, brachyfacial and dolichofacial facial patterns on giving an individual the profile of a crime suspect in the eyes of public security agents.This study had a cross-sectional design, conducted with public security agents of both sexes (n=100), where images of facial composites (police sketches) of individuals with different facial patterns (mesofacial, brachyfacial and dolichofacial) were used. With these images in hand, a questionnaire was created, divided into three parts: the first in which all the images were presented together, allowing comparison among them; the second, in which each image was evaluated separately followed by questions and the third that consisted on a visual analog scale that presented a bar with marks going from 0 to 100, where 0 represented the untrustworthy individual, 50 the individual who could be trusted, and 100 a very trustworthy individual. When all the data had been obtained statistical analyses were performed using the Chi-square and Friedman tests. The level of significance adopted was 5% (α=0.05). The dolichofacial individual was associated with security agents as the most prone to commit crimes and became more insecure and distrustful when compared to the mesofacial and brachyfacial individuals (p <0.001). The dolichofacial profile had a negative influence on the judgment of security agents who attributed to it, a character suspected of a crime and a low level of trustworthiness

Avaliar a influência dos padrões faciais mesofacial, braquifacial e dolicofacial em conceder um perfil de suspeito a cometer crimes aos olhos dos agentes de segurança pública. Este estudo teve delineamento transversal, realizado com agentes de segurança pública de ambos os sexos (n = 100), onde imagens de retratos- falados de indivíduos com diferentes padrões faciais (mesofacial, braquifacial e dolicofacial) foram utilizadas. De posse dessas imagens, foi criado um questionário, dividido em três partes: a primeira em que todas as imagens foram apresentadas juntas, permitindo a comparação entre elas; a segunda, em que cada imagem foi avaliada separadamente seguida de perguntas e a terceira consistiu em uma escala analógica visual que apresentava uma barra com marcações de 0 a 100, onde 0 representava o indivíduo não confiável, 50 o indivíduo em quem se podia confiar, e 100 um indivíduo muito confiável. Após a obtenção dos dados, foram realizadas análises estatísticas utilizando os testes Qui-quadrado e Friedman. O nível de significância adotado foi de 5% (α = 0,05). O indivíduo dolicofacial foi associado pelos agentes de segurança como o mais propenso a cometer crimes e passou mais insegurança e desconfiança, quando comparado aos indivíduos mesofacial e braquifacial (p<0,001). O perfil dolicofacial influenciou negativamente no julgamento dos agentes de segurança que atribuíram-lhe caráter suspeito a cometer crimes e baixo grau de confiabilidade.

Perception on the quality of life related to oral health in preschool children

Introduction: To evaluate the quality of life related to oral health is of paramountimportance, since there are few studies evaluating the OHRQoL (Oral health relatedquality of life) in children of 5 and 6 years. This study aimed to evaluate the impactof caries disease and traumatic dental injuries (TDI) on oral health related qualityof life (OHRQoL) in children of 5 and 6 years of age according to the self reportand the secondary report of the parents, as well as ascertain the agreementbetween them. Methods: A cross-sectional study with 238 children and theircaregivers attended at health units and public schools in the municipality ofJequié (BA), Brazil. After an interview, the children were submitted to oral clinicalexamination to investigate the presence or absence of caries experience and TDI.For data collection, the Scale of Oral Health Outcomes for 5-year-old children (B-SOHO-5) and a sociodemographic questionnaire were used. Differences in OHRQoLscores between sociodemographic and clinical characteristics were comparedusing the Mann-Whitney and Kruskal-Wallis tests. The agreement of the responsesbetween children and parents was compared using Kappa statistics (> 0.60). Thedifference between the total scores of the children and the parents was examinedwith the Wilcoxon test; the Lin coefficient of agreement and the Bland and Altmanmethod were used as measures of agreement. A significance level of 5% ( = 0.05)was adopted. Results:There was a significant association (p< 0.05) between cariesand TDI with OHRQoL according to the children's perception. There was significantmismatch / mismatch between the reports of the child-father and the mother-child pairs in relation to the child's OHRQoL. Conclusion: Caries disease and TDIshave a negative impact on OHRQoL according to the perception of only thechildren. Research has pointed out that parents are not reliable sources forassessing their child's OHRQoL.

Ocorreu discordância/pobre concordânciasignificativa entre os relatos dos pares criança-pai e criança-mãe com relação àQVRSB da criança. Conclusão: A doença cárie e as TDI causam impacto negativona QVRSB de acordo com a percepção apenas das crianças. A pesquisa apontouque os pais não são fontes confiáveis para avaliar a saúde bucal do seu filho.

Effect of mentoplasty on esthetic perception of dental surgeons, dental students and lay persons / Efeito da mentoplastia na percepção estética de cirurgiões-dentistas, estudantes de odontologia e leigos

Objective: was to evaluate the influence of mentoplasty on esthetic perception of dental surgeons, dental students and lay persons. In addition, to determine whether the outstanding chin affects the perceived desire for orthognathic surgery. Material and Methods: An image of an ideal silhouette was created. This image was manipulated to create another six images with different degrees of retrogenia and progenia in increments, advancing and receding the chin on a scale of 5 mm (from +15 to -15 mm) in the anteroposterior and vertical directions. Once the images were obtained, a questionnaire was created, which was evaluated by lay persons, dental surgeons and dental students (n = 50). The evaluators used a visual analog scale to analyze the images, establishing a score ranging from 0 to 10. Associated with the scale, the evaluators were asked whether they wished to have some surgical correction performed if the image in question were a representation of their own facial profile. Results: demonstrated that image H (0 mm) was ranked as the most attractive by the dental surgeons, while the dental students and lay persons scored B (-5 mm) as the best image. In general, images A (+15 mm) and D (-15 mm) were those that most induced a desire for corrective surgery. Conclusion: the prognathic and retrognathic facial profiles were unpleasant and perceptible to the dentist, dental student and lay person. The more projected and retracted the chin was, the greater was the desire to have orthognathic surgery performed. (AU)

Aesthetic perception of the smile related to the vertical position of the lower anterior teeth by afro-descendent laypeople

Introduction: To evaluate the influence of the vertical position of the lower anterior teeth in the aesthetic perception of the smile of Afro-descendent laypeople from different age groups. Materials and Methods: A standard smile was constructed from intraoral photographs of an afro-descendent individual. The vertical position of the lower anterior teeth was gradually changed by moving the teeth up and down within the lip frame in 0.5 mm increments ranging from -1.5 mm to 2.0 mm, regarding point zero. Using a visual analog scale, 150 Afro-descendent Brazilian lay individuals from three different age groups (15-19, 35-44 and 65-74) rated the attractiveness in relation to 8 smiles with altered gingival exposure. Results: There were no significant differences (p>0.05) between male and female raters for the three groups. All the age groups assigned higher scores for the smiles with 0.5 mm coverage of the lower lip on the lower central incisors. However, for the less attractive smiles, there were differences in the opinions of the age groups (p<0,05). Conclusions: the age groups shared similar preferences regarding the most pleasant smile regarding the vertical positions of the lower anterior teeth.

Introdução: Avaliar a influência da posição vertical dos dentes anteriores inferiores na percepção estética do sorriso de leigos afrodescendentes de diferentes faixas etárias. Materiais e Métodos: Um sorriso padrão foi construído a partir de fotografias intraorais de um indivíduo afro-descendente. A posição vertical dos dentes anteriores inferiores foi gradualmente alterada, movendo os dentes para cima e para baixo dentro da moldura do lábio em incrementos de 0,5 mm variando de -1,5 mm a 2,0 mm, em relação ao ponto zero. Utilizando uma escala analógica visual, 150 indivíduos leigos afrodescendentes brasileiros de três diferentes faixas etárias (15-19, 35-44 e 65-74) classificaram a atratividade em relação a 8 sorrisos com exposição gengival alterada. Resultados: Não houve diferenças significativas (p> 0,05) entre os avaliadores masculino e feminino para os três grupos. Todos os grupos etários atribuíram pontuações mais altas para os sorrisos com cobertura de 0,5 mm do lábio inferior nos incisivos centrais inferiores. No entanto, para os sorrisos menos atraentes, houve diferenças nas opiniões dos grupos etários (p <0,05). Conclusão: os grupos etários compartilhavam preferências semelhantes quanto ao sorriso mais agradável em relação às posições verticais dos dentes anteriores inferiores.

Perception of attractiveness of missing maxillary lateral incisors replaced by canines

ABSTRACT Objective: The aim of this study was to evaluate the degree of perception of attractiveness of the smile among dentists, dental students, and lay persons in cases of agenesis of the maxillary lateral incisors replaced by canines for space closure. Methods: A smiling front view extraoral photograph of a 20-year-old woman was digitally altered simulating agenesis and its treatment, by means of: repositioning, reshaping or bleaching the canine, and gingival contour. A questionnaire was distributed to individuals of the three groups (n= 150), with a view to evaluating their degree of esthetic perception. An attractiveness scale was also used, with '0' representing unattractive and '10', very attractive. Results: In the comparative evaluation among all the photographs, the original image obtained the highest level of acceptance. Photograph 'i' (agenesis of both lateral incisors treated with reposition and reshaping of the canines) was ranked as the least attractive by the dentists, whereas the student and lay persons ranked photograph 'f' (agenesis of both lateral incisors treated with reposition of the canines, gingival contour, bleaching and reshaping) as the worst. Conclusion: The methods of treatment most accepted among the dentists and students were those that involved changes in the gingival contour, whereas among lay persons, they were those that involved only reshaping.

RESUMO Objetivo: o objetivo do presente estudo foi avaliar o grau de percepção da atratividade do sorriso por dentistas, estudantes de Odontologia e leigos, em casos de agenesia dos incisivos laterais superiores substituídos por caninos, para fechamento do espaço. Métodos: uma fotografia extrabucal frontal do sorriso de uma mulher com 20 anos de idade foi alterada simulando agenesia e seu tratamento por meio de: reposicionamento do canino, remodelação, clareamento ou contorno gengival. Um questionário foi distribuído aos indivíduos dos três grupos (n= 150), com o objetivo de avaliar o grau de percepção estética. Uma escala de atratividade também foi usada, com '0' representando pouco atraente e '10', muito atraente. Resultados: na avaliação comparativa entre as fotografias, a imagem original obteve o maior nível de aceitação. A fotografia "i" (agenesia de ambos os incisivos laterais tratada com reposição e remodelação dos caninos) foi classificada como a menos atraente pelos dentistas, enquanto os estudantes e os leigos classificaram a "f" (agenesia de ambos os incisivos laterais tratada com reposição dos caninos, contorno gengival, clareamento e remodelação) como a pior. Conclusão: os métodos de tratamento mais aceitos entre dentistas e estudantes foram aqueles que envolviam mudanças no contorno gengival, enquanto entre os leigos foram aqueles que envolviam apenas remodelação.

Prevalence and factors associated with hypertriglyceridemic waist in the elderly: a population-based study / Prevalência e fatores associados à cintura hipertrigliceridêmica em idosos: um estudo de base populacional

Abstract To identify the prevalence and factors associated with hypertriglyceridemic waist (HW) in community-dwelling elderly people in northeast Brazil. Population-based cross-sectional study. Some 316 elderly (≥ 60 years) people of both sexes participated in this study. Data were collected using a questionnaire, based on that used in the Health, Welfare and Aging Study (SABE), in addition to blood tests, blood pressure measurements and anthropometric measurements. The hypertriglyceridemic waist condition was diagnosed using high values of triglycerides (≥ 150 mg/dl) and waist circumference increased ≥ 88 and ≥ 102 cm for women and men, respectively. Logistic regression analysis was used to compare the hypertriglyceridemic waist and associated factors, significance level of 5%. The prevalence of hypertriglyceridemic waist (HW) was 27.1%. The logistic regression model (OR) adjusted showed the condition of HW associated to the feminine sex (OR 4.19), to the insufficiently active elderly (OR 2.41) and with overweight (OR 4.06). A high prevalence (27.1%) of hypertriglyceridemic waist was observed, indicating the female sex, physical inactivity and overweight as key factors associated with hypertriglyceridemic waist in community-dwelling elderly people.

Resumo Identificar a prevalência e os fatores associados à cintura hipertrigliceridêmica em idosos residentes em uma comunidade no nordeste do Brasil. Estudo populacional com delineamento transversal. Participaram do estudo 316 idosos com idade ≥ 60 anos, de ambos os sexos. Os dados foram coletados por meio de um formulário próprio, baseado no questionário usado na Pesquisa Saúde, Bem-Estar e Envelhecimento, além dos exames sanguíneos, aferição da pressão arterial e medidas antropométricas. A cintura hipertrigliceridêmica (CH) foi diagnosticada quando os níveis de triglicerídeos apresentaram valores (≥ 150 mg/dl) e a circunferência da cintura ≥ 88cm para as mulheres e 102 para os homens. Para identificar os fatores associados a CH foi utilizado a análise de regressão logística, com nível de significância 5%. A prevalência de cintura hipertrigliceridêmica foi 27,1%. O modelo de regressão logística (OR) ajustado mostrou a condição de CH associada ao sexo feminino (OR 4.19), aos idosos insuficientemente ativos (OR 2.41) e com sobrepeso (OR 4.06). Foi observada uma alta prevalência de cintura hipertrigliceridêmica em idosos residentes em comunidade, apontando o sexo feminino, a inatividade física e o sobrepeso/obesidade como fatores associados.

Redução da capacidade funcional de idosos residentes em comunidade: estudo longitudinal / Reduced functional capacity of community-dwelling elderly: a longitudinal study

Resumo O objetivo deste estudo foi identificar a incidência e fatores de risco para a redução da capacidade funcional de idosos residentes em comunidade. Foi conduzido estudo de coorte prospectivo em duas fases, 2011 e 2014. A população do estudo foi composta por 202 idosos inicialmente independentes para as atividades básicas da vida diária. Utilizou-se como medida de associação o risco relativo (RR) e seus respectivos intervalos de confiança (IC) 95%, que foram estimados por regressão log-binomial com variância robusta. A incidência da redução de capacidade funcional foi de 15,3%. Os fatores de risco para o declínio funcional foram: estado civil sem união (RR aj = 2,75; IC95%: 1,15 - 6,57) e presença de sintomas de depressão (RR aj = 2,41; IC95%: 1,15 - 5,06), mesmo após ajuste por sexo, faixa etária, renda familiar per capita, diabetes, uso de medicamentos e nível de atividade física. A elevada incidência da redução de capacidade funcional e sua associação com aspectos da relação conjugal e de saúde mental revela a necessidade de considerar tais fatores no planejamento de ações em saúde voltadas à manutenção e recuperação da capacidade funcional dos idosos.

Abstract This study aimed to identify the incidence and risk factors for the reduced functional capacity of community-dwelling elderly. A prospective, two-stage cohort study was conducted in 2011 and 2014. The study population consisted of 202 initially independent older adults for the basic activities of daily living. The relative risk (RR) and its respective 95% confidence intervals (CI) were used as a measure of association and were estimated by log-binomial regression with robust variance. The incidence of lower functional capacity was 15.3%. The risk factors for the functional decline were unmarried status (RRadj = 2.75; 95%CI: 1.15-6.57) and depressive symptoms (RRadj = 2.41; 95%CI: 1.15-5.06), even after adjusting for gender, age group, per capita household income, diabetes, use of medication and level of physical activity. The high incidence of reduced functional capacity and its association with marital status and mental health aspects reveals the need to consider such factors in the planning of health actions aimed at maintaining and restoring the functional capacity of the seniors.

Age and mini-mental state examination score can predict poor-quality spirometry in the elderly: a cross-sectional study

OBJECTIVES: The goal was to identify predictors of poor-quality spirometry in community-dwelling older adults and their respective cutoffs. METHODS: This was a cross-sectional population-based study involving 245 elderly subjects (age≥60 years). The spirometric data were categorized as good or poor quality, and cognitive status was assessed using an adapted version (scaled to have a maximum of 19 points) of the Mini-Mental State Examination. Multivariate analysis was used to assess the association between poor-quality spirometry and sociodemographic, behavioral and health characteristics. The best cutoff points for predicting poor-quality spirometry were evaluated by the receiver operating characteristic curve. RESULTS: In this population, 61 (24.9%) subjects with poor-quality spirometry were identified. After multiple logistic regression analysis, only age and Mini-Mental State Examination score were still associated with poor-quality spirometry (p≤0.05). The cutoff for the Mini-Mental State Examination score was 15 points, with an area under the receiver operating characteristic curve of 0.628 (p=0.0017), sensitivity of 74.5% and specificity of 49.5%; for age, the cutoff was 78 years, with an area under the receiver operating characteristic curve of 0.718 (p=0.0001), sensitivity of 57.4% and specificity of 79.9%. CONCLUSION: Age and Mini-Mental State Examination score together are good predictors of poor-quality spirometry and can contribute to the screening of community-dwelling older adults unable to meet the minimum quality criteria for a spirometric test.

Indicadores antropométricos como preditores na determinação da fragilidade em idosos / Anthropometric indicators as predictors in determining frailty in elderly people

Resumo O objetivo deste artigo é analisar Os indicadores antropométricos como preditores na determinação da fragilidade em idosos. Trata-se de um estudo transversal de base domiciliar e analítico. A pesquisa foi constituída por 316 idosos. A associação entre os marcadores antropométricos e a fragilidade foi testada por meio da técnica de Regressão Logística. Já o poder de diagnóstico de fragilidade, utilizando os marcadores antropométricos e a identificação dos melhores pontos de corte, foi avaliado por meio dos parâmetros fornecidos pela curva Receiver Operating Characteristic. Os indicadores antropométricos de estado nutricional, Perímetro da Panturrilha, Índice de Massa Corpórea e Área Muscular do Braço Corrigida, são inversamente associados à fragilidade, assim o incremento nos valores desses indicadores é fator de proteção para esta síndrome. Recomenda-se que o Perímetro da Panturrilha e o Índice de Massa Corpórea sejam analisados de forma combinada para realizar de forma ainda mais simples a triagem de idosos frágeis, já que possuem boa sensibilidade e têm maior facilidade de mensuração de seus valores.

Abstract The scope of this article is to analyze anthropometric indicators as predictors in determining frailty in elderly people. This is a cross-sectional, family-based and analytical study. The survey was composed of 316 elderly subjects. The association between the anthropometric markers and frailty was tested using the Logistic Regression technique. However, the power of frailty diagnosis using anthropometric markers and the identification of the best cutoff points were evaluated using the parameters provided by the Receiver Operating Characteristic (ROC) curve. The anthropometric indicators of nutritional status: calf circumference, body mass index and corrected arm-muscle area are inversely associated with frailty. Thus, an increase in the values of these indicators is a protective factor against this syndrome. Analyzing body mass index and calf circumference simultaneously in order to perform a simpler screening for frail elderly people is recommended, as these indicators show good sensitivity and are easier to measure.
