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.

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.

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.

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.

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.

Abstract Objective: To evaluate the effectiveness of chewing gums containing CPP-ACP in remineralisation of demineralised enamel around orthodontic brackets. Material and Methods: Enamel blocks from 120 bovine incisors were used. The blocks were flattened and polished, followed by the development of incipient subsurface caries. The blocks have been subjected to a baseline microhardness analysis. Orthodontic brackets were bonded to the exposed area of the blocks, reserving an area for hardness analysis. An in situ crossover (three-way crossover phases of 21 days with an interval of one week between them), controlled, randomised and blind experimental model was used, with the participation of 12 volunteers divided into groups: G1 – negative control group, without chewing gum; G2 – conventional sugar-free chewing gum, without CPP-ACP (placebo); and G3 – sugar-free chewing gum with CPP-ACP. The following parameters were analysed: superficial linear (Ra), volumetric roughness (Sa), and superficial structural loss, which was indicated by Gap measurement (difference between the healthy and treated area). Statistical tests used were the Friedman, Wilcoxon and Shapiro-Wilk, Kruskal Wallis' nonparametric tests and ANOVA. Results: There was a significant reduction in enamel microhardness after demineralisation in all the groups (p<0.05). This deleterious effect was attenuated in the three groups after the final evaluation, although there were no statistical differences (p<0.05); however, the final values did not return to the baseline values (p<0.05). Conclusion: Chewing gum containing CPP-ACP did not promote in situ remineralisation of demineralised enamel around orthodontic brackets.

RESUMO Objetivo: Avaliar a influência da ancoragem mono e bicortical e do diâmetro dos mini-implantes (MIs) na estabilidade primária desses dispositivos. Métodos: 60 MIs autoperfurantes foram distribuídos em seis grupos, de acordo com o diâmetro (1,5 mm, 1,8 mm ou 2,0 mm) e tipo de ancoragem (monocortical e bicortical), e inseridos em costela bovina. A estabilidade primária foi avaliada pelos testes de torque de inserção, micromobilidade e resistência à tração. ANOVA e/ou análise de Tukey foram usadas para realizar comparações intergrupos (p< 0,05). Estatística não paramétrica (Kruskal-Wallis e Mann-Whitney) foi realizada quando a normalidade não foi encontrada (p< 0,05). Resultados: MIs com diâmetros maiores e ancorados bicorticalmente apresentaram maior estabilidade primária em relação ao torque de inserção (p< 0,05) e micromobilidade (p< 0,05). Apenas o diâmetro do MI influenciou os resultados do teste de resistência à tração. MIs de maior diâmetro apresentaram melhor retenção nos testes de resistência à tração (p< 0,001), independentemente da ancoragem mono ou bicortical. Conclusões: a estabilidade primária do MI é dependente de seu diâmetro e tipo de ancoragem. A ancoragem bicortical apresentou maior estabilidade quando comparada à ancoragem monocortical, independentemente das demais variáveis.

ABSTRACT Objective: Assess the influence of mono- and bicortical anchorage and diameter of mini-implants (MIs) on the primary stability of these devices. Methods: 60 self-drilling MIs were distributed in six groups according to diameter (1.5mm, 1.8mm or 2.0mm) and type of anchorage (monocortical and bicortical) in bovine rib. The primary stability was evaluated by insertion torque, micromobility and pull-out strength tests. ANOVA and/or Tukey analysis were used to conduct intergroup comparisons (p< 0.05). Non-parametric statistics (Kruskal-Wallis and Mann-Whitney) were performed when normality was not found (p< 0.05). Results: MIs with larger diameters and bicortical anchorage showed greater primary stability regarding insertion torque (p< 0.05) and micromobility (p< 0.05). Only MI diameter had an effect on the pull-out strength test. Larger diameter MIs presented better retention in pull-out strength tests (p< 0.001), regardless of mono- or bicortical anchorage. Conclusions: MI primary stability is dependent on its diameter and type of anchorage. Bicortical anchorage showed greater stability when compared with monocortical anchorage, independently of other variables.

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 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.

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.

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 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.

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.

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.

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.

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.
