Abstract This study aimed to estimate the prevalence and extent of bleeding on probing and calculus in 12-year-old schoolchildren of Quito, Ecuador, and evaluate the associated factors. We conducted an epidemiological survey with a representative sample of 1,100 12-year-old schoolchildren from public schools in the urban area of Quito, Ecuador. We assessed the periodontal health using the Community Periodontal Index (CPI). The prevalence and extent of the periodontal condition was based on the presence of at least one site with bleeding on probing (BOP), and the presence of dental calculus was also evaluated. We used univariate and multiple multilevel Poisson regression analyses to verify the association between the independent variables and the number of sextants with BOP and calculus. The prevalence of BOP and calculus was 92% and 69.9%, respectively. The adjusted mean of the affected sextants was 4.3 and 2.2 for BOP and calculus, respectively. The mother’s schooling and malocclusion were associated with the number of sextants with bleeding. The mother’s schooling and dental caries experience were associated with calculus. Gingival bleeding and the presence of dental calculus are highly prevalent in 12-year-old schoolchildren from Quito. Gingival bleeding is associated with maternal education and malocclusion, and dental calculus is associated with maternal education and dental caries.

Abstract This observational study aimed to describe and analyze data from two external evaluations of the National Program for Improving Access to and Quality of Dental Specialty Centers (PMAQ CEO), held in 2014 and 2018 in Brazil, which evaluated Dental Specialty Centers (CEO) using a national and census approach. We selected questions through a search in the microdata of the first and second evaluations. The groups were analyzed independently. To compare the groups, nonparametric tests were performed (Mann Whitney U). The formulated hypotheses were: there would be no differences between the data of these groups (h0) and there would be differences between the data of these groups (h1). For qualitative nominal variables, frequency distribution was verified and association tests were performed (chi-square test). The significance level for this study was set at 5%. We observed that orthodontic treatments were found in about 13% of the CEO. Regarding human resources, most professionals were specialists or had MSc or PhD degrees; were civil servants; had been hired by direct administration; or had been hired via public tender. Regarding the work process and inclusion of the CEO in the health care network, we observed a greater number of services that use single and electronic medical records, greater presence of services monitoring and analyzing goals, greater knowledge about monthly average of absenteeism (for 2018); and larger number of services with referrals from primary health care centers (for 2014). Expanding the view on orthodontics and including preventive, interceptive, and corrective treatments at different points in health care networks are essential strategies for achieving comprehensive care in universal health systems.

ABSTRACT Herbal medicine is widely used as an integrative complementary treatment for common chronic diseases, yet potential risks include adverse effects and coprescription Aim This exploratory survey assessed Brazilian dentists’ knowledge, attitudes, and practices regarding phytotherapy Material and Method This study used a consecutive sample of registered dentists who were active in clinical practice and attending advanced training for complex oral rehabilitation at a leading dental school in Latin America. Participants responded to a semi-structured 38-item instrument designed to collect data on sociodemographic, professional and health variables, and on their knowledge, use, prescription and opinions of phytotherapy. Quantitative data were analyzed with descriptive and inferential statistics. Qualitative data were described and analyzed with a thematic approach Results A total 53 dentists responded the survey (88.3% response rate). Six dentists reported formal education in phytotherapy and 33 had informal knowledge. Twenty-one dentists (39.6%) reported using herbal medicine, and 17 (32.1%) prescribed phytotherapy to their patients, mostly traditional medicinal plants. A logistic regression model showed that post-graduate degree and personal use of phytotherapy were associated with phytotherapy prescription. Opinions on how to improve the rational use of phytotherapy included the need for research evidence, specific academic education, and knowledge dissemination to clinicians. As a clinical recommendation, it was proposed that questions on herbal medicine should be asked during the dental patient’s anamnesis Conclusions Dentists with post-graduate degrees and personal use of phytotherapy prescribe herbal medicines for their patients in real-world clinics, regardless of formal education on the subject. Qualitative findings indicate the need to implement scientific initiatives.

ABSTRACT Objective: This study aims to evaluate the correlation between religiosity and spirituality in dental students in the state of Bahia. Methods: Cross-sectional study carried out with 266 dental students from the state of Bahia. To measure religious involvement, the Duke Religious Index (DUREL) was used, while the Spirituality Self Rating Scale (SSRS) was used for spirituality. Results: A total of 266 students were evaluated, with a mean age of 32 years (±11.9), most of them female (62.4%), of self-reported race/color (52.3%), with an income greater than three minimum wages (57.1%) and studying/working from the sixth to the tenth semester (41.0%). The correlations evidenced can be classified as weak for organizational religiosity (OR) (r = 0.406), moderate for non-organizational religiosity (RNO) (r = 0.589) and strong for intrinsic religiosity (RI) (r = 0.677). In the multivariate model, the ORN and RI dimensions proved to be predictors of spirituality, and the elevation of the former implies a consequent increase in spirituality. Conclusion: It is concluded that the RNO and RI dimensions are positively correlated with religiosity.

RESUMO Objetivos: Este estudo objetiva avaliar a correlação entre religiosidade e espiritualidade em acadêmicos de odontologia do estado da Bahia. Métodos: Estudo transversal realizado com 266 acadêmicos do curso de odontologia do estado da Bahia. Para mensuração do envolvimento religioso foi utilizada a escala Duke Religious Index (DUREL) enquanto para a espiritualidade a Spirituality Self Rating Scale (SSRS). Resultados: Foram avaliados 266 acadêmicos, com média de idade de 32 anos (±11,9), sendo em sua maioria do sexo feminino (62,4%), de raça/cor autorreferida (52,3%), com renda maior que três salários mínimos (57,1%) e cursando/atuando do sexto ao décimo semestre (41,0%). As correlações evidenciadas podem ser classificadas como fraca para a religiosidade organizacional (RO) (r = 0,406), moderada para a não organizacional (RNO) (r = 0,589) e forte para e a religiosidade intrínseca (RI) (r = 0,677). No modelo multivariado as dimensões RNO e RI mostraram-se preditores da espiritualidade, sendo que a elevação das primeiras implica um consequente aumento da espiritualidade. Conclusão: Conclui-se que as dimensões RNO e RI estão positivamente correlacionadas à religiosidade.

Abstract Sex estimation is an important procedure in forensic anthropology for human identification. The development of new technologies, such as three-dimensional computed tomography (CT), has provided excellent alternatives for this purpose. This study examined and compared a morphological method for sex estimation using two different approaches – direct measurement of physical structures and tomographic analysis using 3D images. A total of 111 skulls from the Museum of Human Anatomy at the University of São Paulo (MAH-USP) were used, (60 males and 51 females). All specimens were scanned by Philips Brilliance 64 CT scanner equipment and their corresponding images were reconstructed in three-dimensional (3D) models. The morphological characteristics of the skulls were analyzed by an observer who was blinded to the sex of the specimens. Five cranial structures were analyzed: external occipital crest, mastoid process, supraorbital margin, glabella, and mental eminence. The structures were scored 1 to 5 according to Buikstra and Ubelaker and validated by Walker. The success rates of the sex estimates obtained through direct measurement of the dry skulls ranged from 67.4% to 70.4% as compared to 60.2% to 68.1% for CT reconstruction. When analyzed separately, the maximum accuracy of the method was 68.33% in males and 88.24% in females in the physical analysis of structures. The glabella and mastoid process were the most effective structures to estimate sex through both techniques, respectively. Our results show that 3D CT images can be accurately used in the morphological analysis for sex estimation, representing a viable alternative in forensic anthropology.

Abstract The aim of this cross-sectional study was to assess whether favorable factors related to school characteristics have a positive effect on the impact of traumatic dental injury (TDI) on oral health-related quality of life (OHRQoL). An epidemiological survey of oral health was conducted with 12-year-old schoolchildren from Quito, Ecuador. Children were examined for TDI, dental caries, and malocclusion. Individual socioeconomic data were also collected. Information on the physical environment, health practices, and occurrence of negative episodes at school was collected from the school coordinators. The Child Perceptions Questionnaire 11-14 (CPQ11-14) was used to evaluate the OHRQoL (outcome variable). Multilevel Poisson regression analysis was conducted. Severe TDI was associated with higher CPQ11-14 scores, even in the multiple model adjusted for oral health conditions, sex, individual socioeconomic variables, and school-related variables. Children from schools that had an appropriate tooth-brushing environment for their students exhibited a lower impact on OHRQoL, even after adjustment for the occurrence of TDI and other variables. A favorable school environment may exert a positive effect on OHRQoL, independent of the occurrence of TDI.

Resumo Insegurança alimentar é um fenômeno complexo que afeta a saúde e o bem-estar de famílias vulneráveis. Este estudo objetivou investigar a relação entre insegurança alimentar domiciliar, cárie dentária, qualidade de vida relacionada à saúde bucal, e determinantes sociais de saúde entre indígenas adultos. Foi conduzido um estudo transversal com adultos Kaingang entre 35-44 anos da Terra Indígena Guarita, Brasil. Insegurança alimentar foi avaliada pela escala EBIA. Cárie dentária foi avaliada pelo índice CPOD. Participantes responderam o questionário OHIP-14 e uma entrevista estruturada. Foram realizadas análises descritivas e multivariadas usando modelos de regressão de Poisson. A amostra incluiu 107 adultos Kaingang de 97 domicílios. Aproximadamente 95% dos participantes viviam em famílias com insegurança alimentar. Insegurança alimentar grave esteve presente em 58% dos domicílios. O fenômeno foi associado ao Bolsa Família, densidade familiar e percepção dos impactos da saúde bucal na qualidade de vida. O alto número de famílias afetadas pela insegurança alimentar revela a vulnerabilidade social do povo Kaingang. Insegurança alimentar em adultos Kaingang está associada à percepção da saúde bucal e determinantes sociais da saúde.

Abstract Food insecurity is a complex phenomenon that affects the health and wellbeing of vulnerable families. The aim of this study was to investigate the relationship between household food insecurity, dental caries, oral health-related quality of life, and social determinants of health among Indigenous adults. A cross-sectional study was conducted among Kaingang adults aged 35-44 years old from the Guarita Indigenous Land, Brazil. Food insecurity was assessed through the EBIA scale. Dental caries was assessed using the DMFT index. Participants answered the OHIP-14 questionnaire and a structured interview. Descriptive and multivariate analyzes using Poisson regression models were performed. The final sample included 107 adults from 97 households. Approximately 95% lived in food insecure families. Severe food insecurity was present in 58% of the households. The phenomenon was associated to the Bolsa Família benefit, household size, and greater perception of oral health impacts on quality of life. The high number of families affected by food insecurity reveals the social vulnerability of the Kaingang people. Food insecurity in Kaingangs adults is associated to oral health perception and social determinants of health.

Abstract Oral cancer is one of the most prevalent cancers in Brazil. An understanding of how public policies are implemented to address this problem can contribute to the construction of solutions. The “Programa de Melhoria do Acesso e da Qualidade” (PMAQ-AB and PMAQ-CEO) at the level of primary and secondary care are evaluations that also collect data on prevention and monitoring strategies for oral cancer. This study aimed to analyze the results of the incorporation of oral health teams to evaluate the strategies adopted by Brazil regarding the impact on the diagnosis of oral cancer. Of the 17,202 family health teams evaluated, 72.10% had oral health teams (OHT). Considering the strategies for prevention, screening, campaign, and follow-up of suspected cases, 72.27% of the campaign teams and 59.09% of the teams who accompanied suspected cases had OHT. In secondary care, more than 65% of the teams in the Southeast and South regions registered cases of oral cancer, and the referral network was more represented. The inclusion of OHT had a positive impact on campaign actions, follow-up, referral to specialists, and registration of suspected cases throughout Brazil.

RESUMO: Introdução: Má higiene bucal, uso regular de enxaguante bucal e ausência de visitas ao dentista podem corresponder a potenciais fatores de risco para o desenvolvimento de câncer de cabeça e pescoço. Objetivo: Determinar se a higiene bucal está associada à ocorrência de câncer em cavidade oral e cabeça e pescoço em uma amostra brasileira. Método: O estudo caso controle analisou variáveis de higiene bucal, como frequência de escovação, perda dentária, necessidade e uso de prótese e visita regular ao dentista em pacientes de cinco hospitais do estado de São Paulo, pareados por sexo e idade, provenientes do projeto multicêntrico Genoma do Câncer de Cabeça e Pescoço (GENCAPO). Resultados: As neoplasias mais frequentes nos 899 pacientes incluídos foram: bordo de língua (11,41%) e base de língua (10,92%). A análise estatística múltipla encontrou os seguintes valores de odds ratio: escovar uma vez 0,33 (IC95% 0,25 - 0,44); escovar duas vezes 0,42 (IC95% 0,35 - 0,52); uso de fio dental sempre 0,19 (IC95% 0,13 - 0,27); uso de fio dental às vezes 0,19 (IC95% 0,15 - 0,24); sangramento 2,40 (IC95% 1,40 - 4,09); prótese 1,99 (IC95% 1,54 - 2,56), visita ao dentista 0,29 (IC95% 0,22 - 0,37); boa higiene 0,21 (IC95% 0,17 - 0,27); higiene regular 0,20 (IC95% 0,15 - 0,25); e número de dentes ausentes (6 ou mais) 3,30 (IC95% 2,67 - 4,08). Conclusões: Esses dados mostraram que, na população estudada, indicadores de boa higiene, como escovar os dentes e uso do fio dental, foram fatores de proteção para o câncer de boca e cabeça e pescoço, enquanto sangramento e muitos dentes ausentes foram fatores de risco.

ABSTRACT: Introduction: Poor oral hygiene, regular use of mouthwash and absence of visits to the dentist could correspond to potential risk factors for the development of head and neck cancer. Objective: The objective of this study was to determine whether oral hygiene is associated with the occurrence of oral cavity and head and neck cancer in a Brazilian sample. Method: The variables of oral hygiene condition, such as toothbrushing frequency, dental loss, need and use of prosthesis, and regular visit to the dentist in a case-control study were analyzed in patients from five hospitals in the state of São Paulo, Brazil, paired by gender and age, from the multicenter project Genoma do Câncer de Cabeça e Pescoço (GENCAPO). Results: The most frequent malignancies in the 899 patients included were those of the tongue border (11.41%) and tongue base (10.92%). The multivariable statistical analysis found odds ratio values: Brushing once 0.33 (95%CI 0.25 - 0.44); Brushing twice 0.42 (95%CI 0.35 - 0.52); Flossing always 0.19 (95%CI 0.13 - 0.27); Flossing sometimes 0.19 (95%CI 0.15 - 0.24); Bleeding 2.40 (95%CI 1.40 - 4.09); Prosthesis 1.99 (95%CI 1.54 - 2.56); Visiting the dentist 0.29 (95%CI 0.22 - 0.37); Good hygiene 0.21 (95%CI 0.17 - 0.27); Regular hygiene 0.20 (95%CI 0.15 - 0.25); number of missing teeth (6 or more) 3.30 (95%CI 2.67 - 4.08). Conclusion: These data showed that, in the population studied, indicators of good hygiene such as brushing teeth and flossing were protective factors for mouth and head and neck cancer, while bleeding and many missing teeth were risk factors.

Abstract The aim of this study was to verify the precision and applicability of two methods of age estimation, Kvaal’s and Cameriere’s methods, among Brazilian adults. A sample composed of periapical radiographs of canine teeth belonging to 320 Brazilian adults was analyzed, divided into groups according to sex (male and female) and age group (20–29 years, 30–39 years, 40–49 years and 50-59 years). Kvaal’s method presented better results when compared to the results of Cameriere’s method in the general evaluation of each canine tooth, except for the upper left canine (tooth 23), which presented a mean error (ME) with no statistically significant difference between the methods (Kvaal: ME = 7.43, p = 0.4991, Cameriere: ME = 7.55, p = 0.6982). In the evaluation by age groups, Kvaal’s method presented a lower variation between the real age and estimated age when applied to the age groups of 20-29 years and 30-39 years compared to the results provided by Cameriere’s method. With respect to the groups aged 40 to 49 years and 50 to 59 years, Cameriere’s method presented better performance than the results provided by Kvaal’s method. The methods of estimating age proposed by Kvaal and Cameriere are simple and nondestructive and have demonstrated reproducibility and reliability. The Kvaal method was more accurate for the age groups of 20-29 and 30-39 years, and for those over 40 years, the Cameriere method was the most accurate.

RESUMO: Introdução: O perfil epidemiológico de cárie dentária dos povos indígenas é complexo e heterogêneo. A saúde bucal do povo Kaingang, terceira maior população indígena do Brasil, ainda não foi investigada. Objetivo: O objetivo deste estudo foi avaliar a prevalência e severidade de cárie, além dos fatores associados à necessidade de extração dentária entre adultos Indígenas Kaingang. Métodos: Foi realizado um inquérito de saúde bucal entre adultos Kaingang com idade entre 35 e 44 anos residentes na Terra Indígena Guarita, Rio Grande do Sul. Exames clínicos foram realizados a fim de analisar as condições da coroas dentárias e as necessidades de tratamento, seguindo os critérios e diretrizes da Organização Mundial da Saúde e da Pesquisa Nacional de Saúde Bucal SB Brasil 2010. Resultados: O total de 107 Indígenas Kaingang foi examinado. O índice de dentes cariados, perdidos e obturados (CPOD) médio observado foi de 14,45 (± 5,80). Dois terços do escore do indíce foram compostos do componente “perdidos”. A dentição inferior anterior apresentou as maiores taxas de dentes hígidos, enquanto os primeiros molares inferiores apresentaram as menores. Necessidade de extração dentária foi observada em 34,58%, sendo associada com a localização da aldeia, tempo da última consulta odontológica e maior número de dentes cariados. Conclusão: As altas frequências de cárie não tratada e dentes perdidos observados nessa população indicam a falta de assistência adequada. É necessário discutir modelos de atenção à saúde para combater iniquidades sociais e de saúde.

ABSTRACT: Introduction: The epidemiological profile of dental caries for Indigenous Peoples is complex and heterogeneous. The oral health of the Kaingang people, third largest Indigenous population from Brazil, has not been investigated so far. Objective: The purpose of this study was to assess the prevalence and severity of dental caries, in addition to the associated factors of the need of dental extraction among Kaingang adult Indigenous. Methods: A cross-sectional oral health survey was conducted among Kaingang adults aged from 35 to 44 years old living in the Guarita Indigenous Land, Rio Grande do Sul. Clinical exams were performed to analyze the conditions of dental crown and treatment needs. Results: A total of 107 Indigenous adults were examined. Mean DMFT score was 14.45 (± 5.80). Two-thirds of the DMFT score accounted for missing teeth. Anterior lower dentition presented the highest rates of sound teeth, whereas the lower first molars had the lowest. Need for dental extraction was observed in 34.58% and was associated with village location, time of last dental visit, and higher number of decayed teeth. Conclusion: The high frequencies of caries and missing teeth observed in this population indicate a lack of adequate assistance. It is essential to discuss health care models in order to combat avoidable social and health injustices.

Resumo O objetivo do estudo é verificar o padrão facial simplificado a partir dos índices facial (IF), da face superior (IFS) e nasal (IN) de homens e mulheres jovens brasileiros a partir da antropometria indireta aplicada em imagens fotográficas em norma frontal. Foram utilizadas imagens de adultos brancos de 30 anos (± 6 meses), sendo 689 do gênero feminino e 660 do masculino, divididos pela região de nascimento, sendo Sul, Sudeste, Centro-oeste, Nordeste e Norte. Os pontos: násio, zígio, gnátio, estômio, subnasal e alar foram marcados nas imagens por meio do software SAFF 2D®. A partir das coordenadas geradas em pixels, foram calculadas as distâncias lineares entre os pontos de interesse, que foram transformadas em índices. Os índices foram analisados estatisticamente de acordo com a região do nascimento pela análise de variância e o gênero pelo teste t de Student. Com os dados foi possível traçar o perfil simplificado da face da população brasileira de adultos jovens por meio da fotoantropometria. Foram observadas diferenças no perfil facial entre os gêneros e também entre algumas regiões, com maior frequência entre a região N e as demais partes do país (p<0,05). Quando separados por regiões do país, o IFS não mostrou diferença estatisticamente significante (p>0,05) entre os gêneros para nenhuma região. A análise discriminante para estimativa de gênero mostra que melhores taxas de acerto são alcançadas quando considerados os três índices em conjunto. Para a árvore de decisão de estimativa de gênero, o IN desempenhou os melhores resultados, quando comparado aos demais índices analisados.

Abstract The aim of the present study is to describe the simplified facial pattern of young Brazilian men and women using the facial index (FI), upper face index (UFI), and nasal index (NI) in indirect anthropometric measurements applied to frontal photographic images. The images were obtained from 660 adult white men and 689 adult white women aged 30 years ± 6 months, and classified according to regions of birth, as follows: south (S), southeast (SE), midwest (MW), northeast (NE), and north (N). The nasion, zygion, gnathion, stomion, subnasale, and alare landmarks were labeled on the images using the SAFF 2D® software. Based on the coordinates, the linear distances between the landmarks of interest were calculated and presented as indices. The analysis of variance and Student’s t-test were used for assessing the regions of birth and gender, respectively. The collected data allowed obtaining the facial profile of the young adult Brazilian population. There were differences in the facial profiles between men and women and also between some regions, especially between the N and the other Brazilian regions (p<0.05). The UFI did not show a statistically significant difference (p>0.05) between genders for any of the regions. The discriminant analysis for gender assessment demonstrated higher accuracy when the three indices were analyzed together. In the decision tree for gender assessment, the NI showed better results than the other indices.
