Abstract The aim of this study was to evaluate the accuracy of pairs of antagonist teeth (epidemiological criterion) for defining pairs of teeth in occlusal contact (clinical criterion) and to estimate the agreement between the prevalence of “shortened dental arch” (SDA) and “functional dentition” (FD) when occlusal units (OUs) or posterior occluding pairs (POPs) are defined by the epidemiological or clinical criterion. Data were collected in an epidemiological oral health survey conducted in a municipality in Minas Gerais, Brazil. OUs and POPs were defined by the epidemiological criterion (dental crown status) or clinical criterion “gold standard” (carbon paper record of occlusal contacts during habitual maximum intercuspation). SDA corresponded to the presence of an intact anterior region and three to five OUs. FD was based on the concomitant presence of ≥ 1 tooth in each arch, 10 teeth in each arch, 12 anterior teeth, ≥ 3 premolar POPs, and ≥ 1 molar POP bilaterally. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of the epidemiological criterion were calculated. The study included 197 adults. Sensitivity, specificity, PPV, and NPV were 88.5, 87.9, 92.5, and 81.9%, respectively, and accuracy was 88.3%. The epidemiological criterion proved to be valid and could be used in epidemiological studies to calculate the prevalence of reduced dental configurations that consider POPs. The assessment of oral functionality is an aspect that should be included in the diagnosis of the clinical condition of patients, contributing to a more effective individual and collective oral health care plan.

Resumo Avaliar por meio de uma revisão de escopo estudos que abordam a percepção e atitude do cirurgião-dentista diante do atendimento a mulheres em situação de violência. Utilizando os descritores women violence, dentist attendence ou dentist care, foram identificados 473 artigos, sendo incluídos 13, ao final da seleção. Embora a necessidade de capacitação tenha sido predominante, ela não é suficiente. Existe uma fragilidade em se compreender a violência como problema de saúde, de entender o papel do profissional na solução desse problema, os fatores que podem contribuir com seu crescimento ou seu controle. Os resultados revelaram que o cirurgião-dentista apresentou maior dificuldade do que os outros profissionais no enfrentamento e exigem um amplo aprendizado. O reconhecimento dos referidos casos pelo cirurgião-dentista exige a incorporação de medidas educativas que provoquem mudanças culturais, desconstrução de normas de gênero e a desnaturalização desse fenômeno social.

Abstract The purpose of this study was to evaluate, through a scope review, studies that address the perceptions and attitudes of dentists regarding the care of women in situations of violence. Using the descriptors women violence, dentist attendance or dentist care, 473 articles were identified, of which 13 were included at the end of the selection process. Although the need for training was predominant, it was not sufficient. There is a weakness in understanding violence as a health problem, in understanding the role of the professional in solving this problem, and the factors that can contribute to its growth or its control. The results revealed that the dentist had greater difficulty than other professionals in coping with the issue and required extensive training. The recognition of these cases of abuse by the dentist requires the incorporation of educational measures that cause cultural changes, deconstruction of gender norms and the denaturalization of this social phenomenon.

Abstract Objective: To evaluate the direct and oral impact-mediated association between reduced dentitions and the self-perceived need for complete dentures (CD) in dentate adults. Material and Methods: Data from the Brazilian Oral Health Survey (2010) were analyzed. The outcome was self-perceived need for CD. Functional dentition (FDClassV) was defined by the presence of the following criteria: level I - ≥1 tooth in each arch, level II - 10 teeth in each arch, level III - 12 anterior teeth, level IV - ≥ 3 posterior occluding pairs (POPs) of premolars and level V - ≥1 bilateral POPs of molars. Oral impacts were assessed with Oral Impacts on Daily Performances scale. Results: FDClassV was associated with a less self-perceived need for CD both directly and mediated by oral impacts. Dentitions without level V were associated with the outcome mediated by oral impacts. Between individuals with 10 teeth in each arch, self-perceived need for CD was similar for those who had or not anterior teeth and POPs. Individuals with <10 teeth in each arch and level III did not have a higher frequency of self-perceived need for CD compared to those with level II. Conclusion: Oral impacts mediated the association between reduced dentitions and self-perceived need for CD. Individuals with tooth loss may report need for CD, even when they have dental configurations compatible with functionality.

Resumo Objetivou-se identificar se a falta de dentição funcional (DF) está associada com o comprometimento das funções bucais/atividades diárias entre adultos brasileiros. Para isto, foram utilizados dados da Pesquisa Nacional de Saúde Bucal - SB Brasil 2010. A DF foi avaliada pelo critério proposto pela Organização Mundial de Saúde (pelo menos 20 dentes na boca). O instrumento Impactos Odontológicos nos Desempenhos Diários (IODD) foi utilizado para avaliar as atividades diárias/funções bucais. Análises descritivas, bivariadas (Qui-quadrado) e múltiplas (Regressão Logística) foram realizadas, sendo estimado o odds ratio e o intervalo de confiança 95% (OR/IC95%). Foram incluídos e avaliados 9564 adultos. Foram considerados sem DF 2200 adultos (20,5%). Tiveram impacto em pelo menos uma das atividades diárias/funções bucais avaliadas, 55,0% dos adultos. A falta de DF entre adultos foi associada (p ≤ 0,05) com o impacto na fala (1,88/1,33-2,64) e vergonha ao sorrir ou falar (1,35/1,00-1,83). Uma prevalência considerável de falta de DF foi identificada, esta ausência foi associada às atividades diárias/funções bucais (fala e vergonha ao sorrir e falar). A reabilitação dentária de pacientes sem DF deve considerar a devolução destas funções bucais perdidas (fala e vergonha ao sorrir ou falar).

Abstract The scope of this study was to identify if the absence of functional dentition (FD) is associated with a lack of commitment to oral functions/daily activities among Brazilian adults. For this purpose, data from the National Survey of Oral Health (referred to as SB Brasil 2010) was used. FD was evaluated by the criterion proposed by the WHO (at least 20 teeth in the mouth). The Oral Impacts on Daily Performance (OIDP) questionnaire was used to evaluate daily activities/oral functions. Descriptive, bivariate (chi-squared) and multiple (logistic regression) analysis was conducted, and the odds ratio estimated with a 95% confidence interval (OR/CI95%). The research evaluated 9,564 adults, of which 2,200 adults (20.5%) were considered to have poor FD, and at least one of the daily activities/oral functions evaluated had an impact among 55% of adults. The lack of FD between adults was associated (p ≤ 0.05) with the impact on speech (1.88/1.33-2.64) and being ashamed to smile or talk (1.35/1.00-1.83). A considerable prevalence of lack of FD was identified, this absence being associated with the lack of commitment to the daily activities/oral functions. Dental rehabilitation of patients with a lack of FD should consider the restoration of these lost oral functions (speech and being ashamed to smile or talk).

Resumo Avaliou-se a insatisfação com os serviços odontológicos entre idosos brasileiros dentados e edentados e sua associação com variáveis contextuais e individuais. Foram utilizados os dados do Levantamento Nacional de Saúde bucal realizado em 2010 e dados contextuais referentes aos municípios. Análises descritivas, bivariadas e multinível foram realizadas. Incluiu-se 1.989 idosos. Destes, 11,2% dos idosos dentados e 22,1% dos edentados estavam insatisfeitos. Entre os dentados, a insatisfação foi associada com variáveis contextuais (localização do município, índice de desenvolvimento humano, Índice de GINI, presença de Centro de Especialidades Odontológicas e cobertura das equipes de saúde bucal) e individuais pertencentes à atenção à saúde e condições de saúde bucal. Para os idosos edentados, não foi identificado associação com variáveis contextuais. Apenas o motivo do uso do serviço e a satisfação com dentes e boca foram associados. Identificou-se uma prevalência considerável de insatisfação com os serviços, sendo maior entre os idosos edentados. Entre os idosos dentados, foi observado associação com variáveis contextuais.

Abstract The scope of this study was to evaluate dissatisfaction with dental services among dentate and edentulous elderly Brazilians and its association with contextual and individual variables. The data from the National Oral Health Survey conducted in 2010 and contextual variables related to cities were used. Descriptive, bivariate and multilevel analysis was conducted among 1,989 elderly individuals. Of these, 11.2% of dentate and 22.1% of edentulous elderly people were dissatisfied. Among the dentate individuals, dissatisfaction was associated with contextual variables (location of municipality, human development index, GINI Index, the presence of Dental Specialty Centers and the coverage of oral health in public service) and persons related to health care and oral health conditions. For the edentulous individuals, no associated contextual variables were identified. Only the motive for the use of the service and satisfaction with teeth and mouth were associated with dissatisfaction with dental services. A considerable prevalence of dissatisfaction with the services was identified, being higher among edentulous elderly Brazilians. Among dentate elderly Brazilians, an association with contextual variables was detected.

Abstract This study investigated factors that affect the use of complete conventional mandibular dentures (CCMD) by patients of the Brazilian Public Health Service. For this, two hundred and thirty one subjects who received CCMD in the Primary Health Care of the Public Health Service in Belo Horizonte – Brazil were evaluated and divided in Group 1 – irregular/non-wear; Group 2 – regular wear. Multivariate logistic regression analysis was used to create predictive models for CCMD non-wear and included socio-demographic and biological variables, technical quality of CCMD, and user satisfaction. The prevalence of CCMD non-wear was 41.10%. The mean score of CCMD quality was 54.97 (0–100). Not wearing the CCMD was significantly associated with user satisfaction and technical quality (p < 0.05). The lack of retention of the CCMD was the most important factor in the evaluation of satisfaction and quality. The final predictive model (specificity = 92.65%; AROC = 0.8759) for not wearing the CCMD retained the variables CCMD stability (OR = 0.888; 95%CI = 0.827–0.954), freeway space (OR = 0.916; 95%CI = 0.860–0.976), satisfaction with speech (OR = 0.694; 95%CI = 0.612–0.786), and irregular CCMD edges (OR = 3.185; 95%CI = 1.478–6.864). Socio-demographic and biological variables were not associated with patients not wearing the CCMD, whereas technical quality and user satisfaction were strongly associated.

Resumo Propõe-se estimar a prevalência da autopercepção da necessidade de prótese dentária total entre idosos (65 a 74 anos) brasileiros desdentados, assim como identificar seus fatores associados. Trata-se de estudo transversal com base no inquérito nacional das condições de Saúde Bucal da população brasileira, denominado SB Brasil – 2010. A variável dependente foi a autopercepção da necessidade de prótese dentária total, considerando a aquisição de prótese nova ou substituição da existente. Foram conduzidas análises descritivas, bivariadas e múltiplas. Foram incluídos 3514 idosos, destes, 2039 (55,0%) perceberam a necessidade de prótese total. A autopercepção da necessidade de prótese total foi maior entre os que necessitavam de prótese dentária inferior e que estavam insatisfeitos com as suas condições de saúde bucal. Além da alta prevalência da autopercepção da necessidade de prótese identificada, os resultados permitiram identificar que condições normativas e subjetivas de saúde bucal se mantiveram associadas a esta autopercepção entre idosos brasileiros.

Abstract The objective is to estimate the prevalence of self-perception of the need for a full dental prosthesis among toothless elderly Brazilians aged 65 to 74, as well as identify the associated factors. It is a cross-sectional study based on the national survey of oral health conditions of the Brazilian population, called SB Brazil – 2010. The dependent variable was the self-perceived need for full dental prosthesis, considering the purchase of new or replacement of the existing prosthesis. Descriptive bivariate and multiple analyses were conducted on 3514 elderly people, of which 2039 (55%) elderly self-perceived the need for a full denture. The self-perception of the need for a full denture was higher among those who needed dental prosthesis and who were dissatisfied with their oral health conditions. In addition to the high prevalence of self-perception of the need for prosthesis identified, the results identified that normative and subjective conditions of oral health remained associated with this self-perception among elderly Brazilians.

O objetivo desse estudo foi avaliar as características fenotípicas dos isolados de nódulos de mulungu (Erythrina velutina Willd.) e determinar seu fingerprinting molecular por meio de Box-PCR. Todas as bactérias foram avaliadas pelas seguintes características fenotípicas: tempo de crescimento, alteração de pH, cor da colónia e produção de muco. As bactérias isoladas hábeis em renodular o hospedeiro original também foram avaliadas em relação à tolerância ao aumento da salinidade e da temperatura de incubação, capacidade de crescimento utilizando diferentes fontes de carbono, resistência intrínseca aos antibióticos e biossíntese de auxina “in vitro”. O fingerprint molecular foi estabelecido usando a técnica Box-PCR e os isolados foram agrupados pelos perfis obtidos. Dos 22 isolados obtidos, oito foram hábeis em renodular o hospedeiro original. Entre eles, alguns foram tolerantes a 1% de NaCl e a 39° C e todos metabolizaram as fontes maltose, frutose, glicose, sacarose e arabinose, resistiram à rifampicina e produziram auxina. As bactérias isoladas mostraram baixa similaridade genética entre elas e as estirpes de referência, o que indica a grande variabilidade genética dos isolados. Os resultados deste trabalho constituem o primeiro relato sobre bactérias capazes de nodular esta espécie endémica. O estudo mais aprofundado destas bactérias poderá revelar a existência de isolados tolerantes a stresses ambientais e adequados a serem utilizados como futuros inoculantes de mulungu.

This study aims to evaluate the phenotypical characteristics of bacterial isolates from mulungu (Erythrina velutina Willd.) nodules and determinate their Box-PCR fingerprinting. All bacteria were evaluated by the following phenotypic characteristics: growth rate, pH change, colony color and mucus production. The bacterial isolates able to re-nodulate the original host were also evaluated regarding its tolerance to increased salinity and different incubation temperatures, ability to growth using different carbon sources, intrinsic antibiotic resistance and “in vitro” auxin biosynthesis. The molecular fingerprints were set up using the Box-PCR technique and the isolates were clustered by its profiles. Among the 22 bacterial isolates obtained, eight were able to re-nodulate the original host. Among the nodule inducing isolates, some were tolerant to 1% of NaCl and 39° C and all of them metabolized the maltose, fructose, glucose, sucrose and arabinose, were resistant to rifampicin and produced auxin. The bacteria showed low genetic similarity among them and reference strains, which indicates the great genetic variability of the isolates. The results of this work are the first reports about the bacterial isolates able to nodulate this endemic specie. A more deep study of these bacteria may reveal the existence of isolates tolerant to environmental stresses and suitable as a future mulungu inoculant.
