- Abstract
This study aimed to analyze the profile and level of satisfaction of users served in the dental specialty for patients with special healthcare needs (SHCN), based on the Brazilian Program for Improving Access and Quality ("PMAQ") of the Centers for Dental Specialties ("CEO"). This observational, quantitative study used a national secondary database in the public domain. Data were analyzed using the chi-squared test with Bonferroni correction, Student's t-test, and log-linear Poisson regression. Most users of the specialty "SHCN" interviewed were female (74.1% in 2014 and 68.8% in 2018), with a mean age of 41.7 (2014) and 44.9 (2018) years. For every 100 respondents who considered it regular or bad, 171 considered it good, and 199 considered it very good. Regarding satisfaction with the host of the "CEO," there were differences between the regions of Brazil (Midwest, Northeast, Southeast, and South). There has been an increase in the number of "CEO" that serve users with autism spectrum disorder. Generally, the "CEO" network provides humanized and welcoming services, presenting better performance in the second evaluation cycle, according to user perception.

- Abstract
In the transition period from breastfeeding to the introduction of complementary feeding, the choice of food is extremely important for the child's development as many factors may be related. This study aims to investigate, through a systematic review and qualitative meta-synthesis, influence in the selection of foods in the introduction of complementary foods for children, including qualitative studies without language or publication period restrictions. Searches were performed in PubMed, LILACS, SciELO, Cinahl, Embase, Web of Science, and Scopus. Initially, 12,489 articles were selected for tittle reading, 13 were included in the review. Four analytical themes related to factors influencing complementary feeding were identified: family socioeconomic conditions, cultural and family aspects, guidance and advice from health professionals, and factors inherent to the infant. Economic factors, such as the opportunity to offer foods not consumed during the parents' childhood, were emphasized. The influence of grandmothers' opinions and community beliefs and traditions were considered. Trust in pediatricians and community health agents' advice, although considered, conflicted with cultural and family traditions. Mothers/caregivers often preferred to offer foods the child shows preference for, rather than introducing new flavors. The findings underscore the need for a better understanding of qualitative aspects., Competing Interests: Declaration of competing interest The authors declare that they have no conflicts of interest related to this research. There are no financial, personal, or professional relationships that could influence or be perceived to influence the work presented in this manuscript. This research is conducted with the utmost objectivity and transparency., (Copyright © 2024. Published by Elsevier Ltd.)

- Abstract
Food-based dietary guidelines (FBDGs) are tools for promoting healthy eating habits. For the population of children under two years old in Latin America and the Caribbean (LAC), there is a lack of reviews analyzing the quality of these guidelines. The objective of this systematic review is to evaluate publicly available FBDGs for the population under two years old in LAC until mid-2023. Guidelines aimed at caregivers of children were included, sourced from government websites in LAC countries and the Food and Agriculture Organization (FAO) portal. Documents targeted at healthcare professionals were excluded. For qualitative analysis, the Agree II guidelines assessment tool and the FAO guide principles for developing healthy and sustainable diets were used. The results showed that more recently released and revised FBDGs with a greater number of pages obtained better scores in both assessments. Additionally, out of the 32 LAC countries, only 13 had these FBDGs available on websites for public access. As a limitation, this study faced challenges in standardizing the searches on government websites. The authors emphasize the need to develop FBDGs for the population under two years old that align with current health and sustainability needs and promote health education.

- Abstract
Background: Rapid demographic, epidemiological, technological, cultural/behavioural, and educational transitions, as they become more complex, demand new integrated and complementary professional skills and abilities. Interprofessional Education (IPE) is a promising alternative to deal with these changes, especially in courses in the health area. This systematic review was to explore the potentialities and limitations of IPE, from the perspective of undergraduate students, through a thematic synthesis of qualitative studies., Methods: A thematic synthesis of qualitative studies was conducted. The question elaborated for this review was: "What is the impact of interprofessional education on the teaching and learning of students in the health area inserted in Higher Education Institutions?". The search strategy was performed in the electronic databases PubMed, Latin American and Caribbean Literature in Health Sciences (LILACS), Cochrane Library, and Scientific Electronic Library Online (SciELO). In addition, searches were carried out in grey literature on the ERIC platforms, ProQuest Disserts and Theses, and Academic Google. The assessment of the quality of the studies was carried out using the Critical Appraisal Skills Programme tool. Data were summarized through thematic synthesis. From the databases, 8,793 studies were identified. After standardized filters procedures, critical summaries, and assessment of relevance to the eligibility criteria, 14 articles were included., Results: The synthesis of the studies revealed the potential of this teaching approach, arranged in three analytical themes: learning from each other and about them; the value of education and interprofessional practice; patient-centred health care. On the other hand, some limitations were also identified, such as barriers related to EIP; the difficulties related to teaching methodologies., Conclusion: Overcoming the identified limitations can enhance the results of the IPE, in view of its impact on the education of students and on the health care of the population., (© 2023.

- Abstract
The objective of this systematic review was to analyze the quality of the food frequency instruments/scales used in dentistry while considering their psychometric properties. The databases consulted were PubMed (August 7, 2020), Scopus (August 27, 2020), Web of Science (August 27, 2020), Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Dentistry and Oral Sciences Source (via EBSCO) (August 28, 2020), LILACS and BBO (August 25, 2020), gray literature: Proquest (October 1, 2020), Capes Theses Bank (October 1, 2020), Brazilian Digital Library of Theses and Dissertations (October 1, 2020), Google Scholar (October 2, 2020), and proceedings of the International Association for Dental Research (IADR) (October 10, 2020). All databases were updated on December 12, 2022. Articles were initially selected by reading the 6,421 titles and 13 abstracts selected, followed by reading the 8 articles included for full text reading to confirm the eligibility criteria, with the aid of Rayyan software. Databases of the construction and/or validation of instruments/scales for assessing food consumption for use in dentistry (in clinical contexts and/or epidemiological studies), with or without assessment of their psychometric properties, were included. Review studies, letters to editors, and research protocols were excluded. Risk of bias assessment was performed according to the Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) checklist. The extracted data were author, country, instrument language, sample, assessment instrument, instrument structure, type of food, instruments compared with the clinical condition, adaptation of an existing instrument, and psychometric properties evaluated. The selection, risk of bias analysis, and data extraction processes were performed by two independent evaluators. Seven studies were identified. The instruments available in the literature were in English, Japanese, Creole, and Malay. Only one study performed translation and cross-cultural validation of an instrument, whereas the others were construction studies. One study did not assess psychometric properties. Regarding the quality assessment and general classification of the studies by the COSMIN checklist, all were considered "inadequate," with reliability (test-retest) being the most validated psychometric property; only one study carried out the validation of all psychometric properties measured in COSMIN. Regarding the quality of the instruments presented, all the studies were classified as "inadequate" in the general assessment. Advances are needed in the validation process., (© 2023 S.

- Abstract
The aim of this study was to perform a cross-cultural adaptation of the Brazilian version of the Dental Neglect Scale (DNS). The process included (i) Translation; ii) Synthesis; iii) Back translation; (iv) Critical analysis by a committee of experts; (v) Pilot studies (n1=30 + n2=30); and (6) Evaluation and refinement of the instrument. The validated DNS presented a Content Validity Index (CVI) equal to 1.0 for the total score, as well as for each item. In the pilot studies, a minimum agreement level of 80% in understanding was achieved. DNS was properly adapted for Brazilian Portuguese, and it needs further study in a representative sample for reliability and construct validity assessment.

- Abstract
The organization of health systems in Health Care Networks (HCN) presents itself as a strategy to overcome the fragmentation of maternal and child health actions and services and to qualify care management. The objective of this study was to validate the Instrument for Evaluation of Maternal and Child Health Care Networks (IARAMI), adapted from the Evaluation Tool of Health Care Networks. The validation process comprised face and construct validation. The methodology used for face validation included the conceptual and semantic adaptation of the instrument and analysis by a panel of experts, through the modified consensus e-Delphi technique. After face validation, IARAMI was applied in a sample of 99 health managers of municipalities in the state of Paraná. The construct validation was conducted through the internal consistency analysis using Cronbach's alpha coefficient and factorial analysis. The factorial analysis technique was applied to each of the dimensions of the instrument, enabling the analysis of communalities. The results showed that IARAMI presented reliability and validity, proving to be a tool that can help managers and health workers in the planning, management, and evaluation of the degree of integration of the maternal and child care network.

- Abstract
Objectives: The aim of this study was to assess the structural validity of the Oral Health Impact Profile-14 (OHIP-14) instrument in Indigenous and non-Indigenous populations from Australia and Brazil using a network analysis approach., Methods: Cross-sectional data collected using OHIP-14 were obtained for Indigenous and non-Indigenous populations from Australia and Brazil. Networks were estimated using the Gaussian graphical model. Items of the OHIP-14 instrument are represented as nodes and the partial correlations between items as edges. Dimensionality was assessed using exploratory graph analysis. Structural consistency and item stability were computed using a bootstrap sampling method. Standardized node strength across each dimension was also calculated., Results: Four dimensions were identified across all samples, although the item arrangement of most dimensions presented variation. Similarities with the theoretical domains of the instrument were found. Items from the conceptually derived OHIP-14 domains formed separated clusters or blended with other items in a single dimension. Most dimensions across all samples showed an acceptable structural consistency. Item stability revealed some discrepancies among items of dimensions of both Indigenous networks., Conclusion: The psychometric network perspective adopted in this study provides validation of the OHIP-14 structure in Indigenous and non-Indigenous populations. The structural consistency and item stability analyses showed that both Indigenous networks present a higher number of cross-domain items and less defined boundaries between dimensions. These findings indicate that OHIP-14 does not measure attributes in the same extent among different cultures., Knowledge Transfer Statement: This study demonstrates a new analytical framework from which to conceptualize and interpret the construct oral health-related quality of life using the Oral Health Impact Profile (OHIP-14). Network graphs facilitate knowledge translation of findings to professionals with no expertise in psychometric methods. OHIP-14 is a valuable tool to oral health research and clinical practice. Differences in conceptions of health may influence the extent that the instrument measures oral health impacts. Consequently, dimension scores do not always provide appropriate measures and should be avoided in research reports and assessments of treatment outcomes.

- Abstract
Background & Aims: The symptoms of xerostomia and taste alteration are adverse effects which frequently occur in patients under chemotherapy and once associated they can potentially impair their nutritional status. The aim of this study was to investigate the association of xerostomia and taste alterations in patients being treated by neoplastic chemotherapy., Methods: Fifty patients scheduled to receive neoplastic chemotherapy were followed for their first two chemotherapy cycles for solid tumors and the Chemotherapy-Induced Taste Alteration Scale (CiTAS) was adopted. Xerostomia was defined by the presence of dry mouth complaints reported by the patients and signs of hyposalivation identified during the intraoral examination., Results: Of the 50 patients, 33 were women, mean age; 61,48 ± 9,07 years, and 17 were men, mean age; 57,35 ± 11,50 years. The most common tumor was located in the breast affecting 15 patients (30%). The Mann-Whitney test showed that the mean scores of CiTAS were significantly higher for those patients who reported having xerostomia when compared with those without xerostomia after the first two chemotherapy cycles. The cofounding variables such as age, smoking habits and use of antidepressants were not statistically associated with taste alterations (p > 0.05)., Conclusions: Taste alterations were worse for patients who complained of xerostomia during the first two cycles of antineoplastic chemotherapy and the association of both symptoms can potentially impair their nutritional status and quality of life., Competing Interests: Declaration of competing interest The authors declare that they have no conflict of interest., (Copyright © 2021 European Society for Clinical Nutrition and Metabolism.

- Abstract
Early childhood caries (ECC) is a global problem, disproportionately affecting disadvantaged populations. The aim of this study was to evaluate systematically the available scientific evidence on the effectiveness of methods for ECC prevention. Six electronic databases were searched. Two independent reviewers selected the publications and analysed the quality of the included systematic reviews. Thirteen studies were included. Overall, eight reviews were classified with methodological quality critically low using the AMSTAR 2, whereas five reviews achieved a high risk of bias using the ROBIS tool. The methods identified that were positively related to the prevention of ECC were as follows: preventive dental programmes for pregnant women; advice on diet and feeding; prenatal oral health care; integration of maternal and children's oral health promotion into nursing practice; maternal oral health programmes undertaken by non-dental health professionals; dental health education in combination with the use of fluoride for children; early preventive dental visits; and the use of fluoride varnish and toothpastes with more than 1000 ppm of fluoride. The currently available evidence supporting the effectiveness of methods for prevention of ECC, although suggesting some methods of greater potential, is still lacking due to the methodological quality of the systematic reviews and the included primary studies., (© 2021 BSPD, IAPD and John Wiley & Sons Ltd.)

- Abstract
This study explores associated factors and perceptions of oral health among crack users recruited in open drug scenes in Brazil. A mixed methods approach was used. The quantitative component analysed findings from a large ( N = 7381), population-based survey. The outcomes under analysis were 'self-perception of oral health' and 'self-reporting of problems affecting the mouth, teeth and gingiva (gums)'. The qualitative component comprised a focus group, with 12 individuals recruited from a drug treatment clinic. Lower self-perception of oral health problems vis-à-vis a higher prevalence of problems affecting the mouth, teeth, and gingiva were found in users who had a lower level of education, used substances daily, had worse self-perception of physical health, did not receive health care and regularly used alcohol and/or tobacco. The results show an association between substance use and decline in oral health, as well as the lack of health services focusing on such issues. Oral health services should be emphasised as a gateway to the health system. So far, the putative cross-referral between services and professionals working in oral health and other health professionals working in the field of drug dependence has not been observed.

- Abstract
Molar incisor hypomineralization (MIH) is an enamel condition characterized by lesions ranging in color from white to brown which present rapid caries progression, and mainly affects permanent first molars and incisors. These enamel defects usually occur when there are disturbances during the mineralization or maturation stage of amelogenesis. Both genetic and environmental factors have been suggested to play roles in MIH's development, but no conclusive risk factors have shown the source of the disease. During head and neck development, the interferon regulatory factor 6 (IRF6) gene is involved in the structure formation of the oral and maxillofacial regions, and the transforming growth factor alpha (TGFA) is an essential cell regulator, acting during proliferation, differentiation, migration and apoptosis. In this present study, it was hypothesized that these genes interact and contribute to predisposition of MIH. Environmental factors affecting children that were 3 years of age or older were also hypothesized to play a role in the disease etiology. Those factors included respiratory issues, malnutrition, food intolerance, infection of any sort and medication intake. A total of 1,065 salivary samples from four different cohorts were obtained, and DNA was extracted from each sample and genotyped for nine different single nucleotide polymorphisms. Association tests and logistic regression implemented in PLINK were used for analyses. A potential interaction between TGFA rs930655 with all markers tested in the cohort from Turkey was identified. These interactions were not identified in the remaining cohorts. Associations (p<0.05) between the use of medication after three years of age and MIH were also found, suggesting that conditions acquired at the age children start to socialize might contribute to the development of MIH., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Background: People with disabilities tend to have greater oral health problems compared to those without disabilities. This may be due to barriers they come across in accessing dental services., Objectives: The objective of this systematic review was to provide a critical digest of the scientific literature concerning barriers and facilitators of access to oral health services for people with disabilities., Methods: The electronic databases PubMed, Scopus, Web of Science, Latin American and Caribbean Health Sciences Literature (LILACS), and Brazilian Library of Dentistry (BBO) were searched using keywords relevant to the subject. The search was not restricted to specific languages or years of publication; all relevant studies were translated and reviewed., Results: Sixteen studies including 14 articles, a doctoral thesis, and a monograph were selected, and their quality was analysed using the Downs and Black assessment tool. Barriers to dental services were divided into physical or nonphysical based on the dentist's perspective, as per the perception of parents/guardians or by the persons with disabilities. The barriers that emerged included the dentist's lack of preparation to assist people with disabilities, structural problems of access to dental offices, communication difficulties, and lack of awareness regarding the need for dental treatment for the disabled person., Conclusion: It is concluded that people with disabilities continue to run into complex physical, behavioural, or multidimensional barriers in accessing dental services. Improved training of dentists for the care of this population is hereby emphasized. The legal framework enabling access to dental care for people with disabilities must also be respected in each country., Competing Interests: The authors declare that they have no financial affiliation (e.g., employment, direct payment, stock holdings, retainers, consultantships, patent licensing arrangements, or honoraria) or involvement with any commercial organization with direct financial interest in the subject or materials discussed in this manuscript or any such arrangements existed in the past five years. No potential conflicts of interest relevant to the present article were reported., (Copyright © 2020 Saulo V. da Rosa et al.)

- Abstract
The profiles of polytraumatized patients in intensive care units were characterized. Serum and salivary markers were compared with normality between Classes I and II of APACHE II and between periods of hospitalization; these results were correlated. This was a prospective study on saliva charts and collection (n = 70). Profile: male, 27 years old, blunt traumas and collisions. Serum parameters with normality: decrease in pH, creatinine at admission to Class I, and at 48 and 72 hours in both classes; K+ at 48 h in Class II; Ca+ on admission in both classes and at 72 h in Class I. Increase in urea at 72 h in Class II, glucose at all times and in all classes, and Ca+ at 48 h in both classes. Class II had high Na+ at 48 and 72 h compared to Class I. In Class I, creatinine reduction occurred in 48 h and 72 h compared to admission and an increase of Ca+ at 48 h with admission. In Class II, pH and Na+ increased at 48 h and 72 h compared to admission. K+ decreased from admission to 48 h and increased from 48 h to 72 h. Urea increased from 48 to 72 hours. Creatinine decreased from admission to 48 and 72 hours. Ca+ increased from admission to 48 hours and decreased from 48 to 72 hours. There was an increase in the saliva levels in both classes and times in relation to normality. There was an increase in urea at admission, glucose at 72 h, and Ca+ at 48 h in Class II compared with Class I. Class I urea increased from admission to 48 h and Ca+ decreased from admission to 48 h. Class II urea decreased from 48 h to 72 h. Strong or very strong positive correlation was identified between blood and creatinine saliva at all times and regular and negative Ca+ at 72 h. This study provides evidence that salivary and serum biomarkers can be used together to monitor the evolution of the clinical symptoms of ICU patients., Competing Interests: The authors have declared that no competing interests exist.

- 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.

- Abstract
Introduction: In Brazil, the undergraduate dental education still remains fragmented and dissociated from its social context, with emphasis on the individualistic and private aspects of dental health. This study aimed to analyze the training and development of university professors of dentistry in stricto sensu postgraduate programs in Brazil., Materials and Methods: Delphi electronic methodology was used within a qualitative-quantitative design to gather data from a panel of 58 experts. Discussions representing the analytic axis focused on: (i) the evaluative processes of higher education, in particular stricto sensu postgraduate programs, and their influence on academic activities in undergraduate dentistry courses and (ii) policies for training and developing university professors., Results: Of the experts, 30 participated in the first round, 24 in the second, and 19 in the third. They considered the training of university professors in dentistry to be highly specialized and technologically focused and indicated the review of political-pedagogic aspects of the educational sphere, as well as the social, economic, cultural, epidemiologic, and professional aspects of training and preparation prescribed by the National Curricular Guides for graduate courses in dentistry. An adequate process of evaluating the official organs and regulators of postgraduate stricto sensu programs, as well the programs themselves, should be implemented., Conclusion: The experts stated that changes to the university teaching system are necessary, even in the field of dentistry. Mechanisms for evaluating areas and professors were inadequate, and the training was overly specialized and not consistent with the social reality of the country., (© 2019 John Wiley & Sons A/S.

- Abstract
Objectives: To compare two different models of public oral health in primary care services, a so-called family health strategy (FHS), as opposed to non-FHS services designated as 'conventional' healthcare (CHC), regarding the presence and extent of the attributes of 'good' primary healthcare (PHC). The null hypothesis of this study is that the attributes do not differ between the FHS and CHC., Design: Cross-sectional., Setting: Public PHC services in Curitiba, the state capital of Paraná., Participants: PHC users of the public oral health network (n=900) and dentists active in this municipal network (n=203)., Primary and Secondary Outcome Measures: The Primary Care Assessment Tool (PCATool)-Dentists and PCATool-Users were used to analyse the primary outcomes ('essential' attributes) and secondary outcomes ('derived' attributes) in the PHC., Results: Overall, the primary care services in oral health were well evaluated, both by users and by dentists, with mean scores ascribed to PHC attributes mostly above the cut-off point (6.6). The exception for users were affiliation (6.36; 95% CI 6.11 to 6.60) and accessibility (5.83; 95% CI 5.78 to 5.89); and for dentists the accessibility (5.80; 95% CI 5.63 to 5.96). When comparing FHS and CHC, there was a superiority of the FHS model, which reached a general mean score of 7.53 (95% CI 7.48 to 7.58) among users and 7.56 (95% CI 7.45 to 7.67) among dentists; on the other hand, the CHC general mean score was of 6.61 (95% CI 6.49 to 6.73) and 6.68 (95% CI 6.56 to 6.80) respectively for users and dentists., Conclusions: The results reveal a reasonable level of attainment of PHC attributes in the services investigated. Nevertheless, public health managers should make efforts to reduce the difficulties faced by users in accessing dental care. The more positive results achieved by FHS services indicate that the provision of oral healthcare under this strategy should be expanded., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

- Abstract
Despite high prevalence, the etiopathology of melasma is not fully understood. Nevertheless, many factors have been associated with the disease, including: sun exposure, sex steroids hormones, drugs, stress, and pregnancy. The high occurrence within familiars (40-60%) suggests a genetic predisposition to the disease. This study explored, through complex segregation analysis (CSA), the inheritance model that best fit the family segregation pattern of facial melasma when accounting for the main epidemiological risk factors. We evaluated 686 subjects from 67 families, and 260 (38%) of them had facial melasma. The CSA model, adjusted for age, skin phototype, sex, sun exposure at work, hormonal oral contraceptive, and pregnancy, evidenced a genetic component that was best fitted to a dominant pattern of segregation. Melasma results from an interaction between exposure factors (e.g. pregnancy, hormones, and sun exposure) over genetically predisposed individuals.

- Abstract
Aim: This study aimed to investigate the associations between human development and the demographic ratio of dentists with the prevalence of dental caries at 12 years of age in large Brazilian cities., Materials and Methods: Data were collected from 27 state capitals, Secondary databases were used: the municipal human development index (MDHI); the ratio of dentists qualified to exercise their profession according to the number of inhabitants; and the decayed, missing or filled teeth index (DMFT). Pearson correlation coefficient analysis and multiple logarithmic regression analysis were performed., Results: The MDHI showed a strong correlation with DMFT and explained 48.1% of the variation in the cities. The ratio of dentists to the number of inhabitants displayed an insignificant, weak correlation with the variations in the DMFT., Conclusion: Social factors strongly influence the oral health/ disease process in Brazilian capitals, thus actions are needed for the promotion of health at more distal, or structural levels that modify the environment, thus enabling healthier choices for individuals. These results challenge traditional beliefs that only the ratio of professional dentists to inhabitants and the provision of dental services have beneficial effects on the prevention and control of oral health problems., Clinical Significance: The prevalence of dental caries is strongly correlated with social factors, as the MDHI.

- Abstract
Some barriers to dental treatment during pregnancy are poorly understood, especially those related to psychosocial factors, which are better explored in qualitative studies. The aim of this systematic review was to explore the barriers and facilitators to dental care during pregnancy through a thematic synthesis of qualitative studies. Qualitative or mixed-methods studies published in English, Portuguese, Spanish and French, from 2000 to 2016, were included. The search strategies were conducted in PubMed, Scopus, Web of Science, LILACS, BBO and CINAHL. To evaluate the quality of the studies, we used the Critical Appraisal Skills Programme tool. Thematic synthesis was performed in order to interpret and summarize the results. From 2,581 screened studies, ten were included in the synthesis. We found 14 analytical themes related to barriers and facilitators to dental care during pregnancy that interacted in complex ways: physiological conditions, low importance of oral health, negative stigma regarding dentistry, fear of/anxiety toward dental treatment, mobility and safety, financial barriers, employment, time constraints, social support, lack of information, health professionals' barriers, family and friends' advice, beliefs and myths about the safety of dental treatment. Myths and beliefs about oral health and dental treatment during pregnancy appear to be the most frequent barriers, both to pregnant women and to dentists or other health professionals. The findings of this review may support new studies, especially to test intervention protocols and to guide effective public policies for the promotion of oral health during pregnancy.

- Abstract
Nonsyndromic cleft lip with or without cleft palate (NSCL±P) compromises oral health, leading to missing or malformed teeth, and hampering oral hygiene. Apart from anatomic damages, NSCL±P also culminates in an impact on the routine quality of life with social privation and psychological embarrassment., Objective: To evaluate the impact of NSCL±P on oral health-related quality of life., Material and Methods: The study was classified as exploratory and descriptive, with quantitative approach. Patients with NSCL±P treated between August 2013 and September 2014 at the Cleft Lip and Palate Integral Care Center (CAIF), Curitiba, Brazil, were invited to participate. Age and sex-related data were collected, as well as level of education, financial income, type of orofacial cleft, use of orthodontic and prosthetic appliances, and number of previous orofacial surgeries. Selected patients were asked to answer the Oral Impact on Daily Performance (OIDP) questionnaire designed to measure the impact of oral health on daily performances., Results: The sample was composed of 103 (44.59%) women and 128 (55.41%) men, with mean age of 19.74 ± 10.20 (7-65) years. The OIDP values ranged from 1 to 175 in 114 (49.35%) patients (mean: 22.38), whereas 117 patients (50.65%) presented total OIDP value equal to zero. High negative impact of NSCL±P on daily performances was detected when associated with the female sex (p=0.037). Daily performances related to phonetics (OIDP2; 2.63) and aesthetics (OIDP5; 2.48) presented the highest average values when compared to other daily performances, except OIDP6. The main symptoms and reported oral problems comprised the aesthetic dissatisfaction., Conclusions: Almost half of the patients evaluated in this study showed negative impact of NSCL±P in the performance of daily activities.

- Abstract
Objective: To identify the impact of MUC5B polymorphisms on dental caries., Methods: A case-control study was performed with patients recruited at Pontifícia Universidade Católica do Paraná. These individuals were aged 12 years old or more. Dental caries was diagnosed using the International Caries Detection and Assessment System, and the effects of socioeconomic, dietary, and hygiene factors on dental caries were investigated. Furthermore, buccal cells were collected, and their DNA was extracted and amplified using PCR. Uni-, bi-, and multivariate analyses were performed., Results: Two hundred patients were recruited, 100 were assigned to the case group and 100 to the control group. In the bivariate analysis, the following variables showed significant results: ethnicity (p = .008), biofilm (p < .001), and gingivitis (p < .001). The MUC5B gene affected dental caries with the markers rs2735733 (p < .001), rs2249073 (p < .001), and rs2857476 (p < .001). In the multivariate analysis, the biofilm variable remained significant (p = .026), as did the following markers from the MUC5B gene: rs2735733 (p = .019), rs2249073 (p < .025), and rs2857476 (p < .005)., Conclusion: Genetic variations in the MUC5B gene can influence dental caries., (© 2017 John Wiley & Sons A/S.

- Abstract
Despite the fact that dental care attendance during pregnancy has been recommended by guidelines and institutions, the demand for dental services is still low among pregnant women. The aim of this study was to identify and analyze the determinants of dental care attendance during pregnancy. We performed a systematic literature search in the electronic databases PubMed, Scopus, Web of Science, Latin American and Caribbean Health Sciences Literature, Brazilian Library in Dentistry, Cumulative Index to Nursing and Allied Health Literature, and Medline using relevant keywords. Studies were filtered by publication year (2000-2016) and language (English, Portuguese, Spanish, and French). The included studies were assessed for quality. Their characteristics and statistically significant factors were reported. Fourteen papers were included in the review. The prevalence of dental service usage during pregnancy ranged from 16 to 83%. Demographic factors included women's age, marital status, parity, and nationality. The socioeconomic factors were income, educational level, and type of health insurance. Many psychological and behavioral factors played a role, including oral health practices, oral health and pregnancy beliefs, and health care maintenance. Referred symptoms of gingivitis, dental pain, or dental problems were perceived need. Demographic, socioeconomic, psychological, behavioral factors and perceived need were associated with the utilization of dental services during pregnancy. More well-designed studies with reliable outcomes are required to confirm the framework described in this review., (© 2018 S. Karger AG, Basel.)

- Abstract
Genetic studies have identified several genes and genomic regions contributing to the control of host susceptibility to leprosy. Here, we test variants of the positional and functional candidate gene SOD2 for association with leprosy in 2 independent population samples. Family-based analysis revealed an association between leprosy and allele G of marker rs295340 (P = .042) and borderline evidence of an association between leprosy and alleles C and A of markers rs4880 (P = .077) and rs5746136 (P = .071), respectively. Findings were validated in an independent case-control sample for markers rs295340 (P = .049) and rs4880 (P = .038). These results suggest SOD2 as a newly identified gene conferring susceptibility to leprosy., (© The Author 2016. Published by Oxford University Press for the Infectious Diseases Society of America.

- Abstract
Objective: To explore high-risk behaviors and experiences with traffic law among night drivers in Curitiba, Brazil., Method: Data from 398 drivers on sociodemographic parameters, high-risk behaviors, experiences with traffic law, and traffic law violations were collected through interviews conducted at sobriety checkpoints. Exploratory-descriptive and analytical statistics were used., Results: The mean age of the participants was 32.6±11.2 years (range, 18 to 75 years). Half of the drivers reported having driven after drinking in the last year, predominantly single men aged 18 to 29 years who drive cars and drink alcohol frequently. Only 55% of the drivers who had driven after drinking in the last year self-reported some concern about being detected in a police operation., Conclusions: A significant association was found between sociodemographic variables and behavior, which can help tailor public interventions to a specific group of drivers: young men who exhibit high-risk behaviors in traffic, such as driving after drinking alcohol, some of whom report heavy alcohol consumption. This group represents a challenge for educational and enforcement interventions, particularly because they admit to violating current laws and have a low perception of punishment due to the low risk of being detected by the police.

- Abstract
Identify and analyze cases of child and adolescent abuse and neglect in Curitiba, Brazil. This is an exploratory descriptive study that takes a quantitative approach. Secondary data from the reporting registry of the Network for the Protection of Children and Adolescents at Risk for Violence in Curitiba, Brazil, dating from 2004 to 2009, were analyzed. Variables included the victims' sociodemographic profile, place of notification, type, nature and severity of abuse, information about the author of the aggression or abuse, and physical lesions. The frequency distribution and associations between the variables were analyzed using the Chi-square test at a 5% significance level. The analysis of 19,316 records showed that domestic violence, abuse and neglect directed against children and adolescents were the most frequently recorded situation, with 17,082 cases (88.4%) distributed in the following manner: neglect, with 9742 reports (57.0%); physical violence, with 1341 reports (7.9%); sexual violence, with 796 reports (4.7%); psychological violence, with 574 reports (3.4%); and abandonment, with 190 reports (1.1%). Of the total, 43.9% were considered severe cases. The most affected age group was between 5 and 14 years of age, with balance between genders. In the majority of cases, the mother was registered as the author of the abuse or neglect. Physical sequelae (20.2%) mostly affected the head and upper and lower limbs, with consequent lesions manifesting as bruises, cuts, and fractures. An increase in the visibility of domestic violence and children and adolescents abuse and neglect has been observed in the city during the last few years, suggesting the effectiveness of the reporting strategies proposed by the protection network. It is important to increase social security and public welfare policies to prevent child and adolescent abuse and neglect, focusing on family support., (Copyright © 2014 Elsevier Ltd.

- Abstract
This article presents an integrative literature review that analyses the advances and challenges in oral health care of the Brazilian primary health care system, based on a political agenda that envisages re-organising the unified health system (SistemaÚnico de Saúde - SUS). It is presumed that the actions suggested by the Alma-Ata Conference of 1978 are still up-to-date and relevant when adapted to the situation in Brazil. Several studies and policies are reviewed, including works demonstrating the importance of primary care as an organising platform in an integrated health-care network, Brazil's strategy for reorganising the primary care network known as the Family Health Strategy, and the National Oral Health Policy. This review discusses results obtained over the last twenty years, with special attention paid to changes in oral health-care practices, as well as the funding of action programmes and assistance cover. The conclusion is that oral healthcare in the Brazilian primary health care system has advanced over the past decades; however, serious obstacles have been experienced, especially with regard to the guarantee of universal access to services and funding. The continuous efforts of public managers and society should focus on the goal of achieving universal coverage for all Brazilians., (© 2013 FDI World Dental Federation.)

- Abstract
Hepatitis C virus (HCV) has become a major public health issue and is prevalent in most countries. We examined several MASP2 functional polymorphisms in 104 Brazilian patients with moderate and severe chronic hepatitis C using the primers set to amplify the region encoding the first domain (CUB1), a critical region for the formation of functional mannan-binding lectin (MBL)/MBL-associated serine proteases (MASP)-2 complexes, and the fifth domain (CCP2), which is essential for C4 cleavage of the MASP2 gene. We identified five single nucleotide polymorphisms in patients and controls: p. R99Q, p. D120G, p.P126L, p.D371Y, and p.V377A. Our results show that the p.D371Y variant (c.1111 G > T) is associated with susceptibility to HCV infection (p = 0.003, odds ratio = 6.33, 95% confidence interval = 1.85-21.70). Considered as a dominant function for the T allele, this variant is associated with high plasma levels of the MASP-2 in hepatitis C patients (p < 0.001). However, further functional investigations are necessary to understand the degree of involvement between MASP2 and the HCV susceptibility., (Copyright © 2011 American Society for Histocompatibility and Immunogenetics.

- Abstract
Despite recent advances revealing genetic factors influencing caries susceptibility, questions regarding the model of inheritance involved are yet to be addressed. We conducted a Complex Segregation Analysis on decayed teeth in a sample of homogenous, isolated families recruited from the Brazilian Amazon. A dominant, major gene effect controlling resistance to phenotype was detected. The frequency of the resistance allele "A" was 0.63; mean numbers of decayed teeth were 1.53 and 9.53 for genotypes AA/AB and BB, respectively. These results represent a step toward a description of the exact nature of the genetic risk factors controlling human susceptibility to caries.

- Abstract
Vitiligo is a chronic disease characterized by macules devoid of melanin and identifiable melanocytes. Adhesion of melanocytes to the basement membrane by integrin CCN3 is mediated through collagen IV receptor DDR1. We hypothesize that genetic variants of the DDR1 gene are associated with the occurrence of vitiligo. To test this hypothesis, we genotyped 10 DDR1 tag single-nucleotide polymorphisms (SNPs) in 212 trios composed of an affected child and both parents. Associated markers were then genotyped in 134 independent, unrelated individuals with vitiligo and 134 unrelated controls. Allele T of tag SNP rs4618569 was associated with an increased risk for vitiligo in the family trios (P=0.002, odds ratio (OR)=5.27; 95% confidence interval (CI)=1.59-17.40), whereas allele C of tag SNP rs2267641 was associated with an increased risk for vitiligo in both family-based and case-control populations (P=0.01, OR=3.47; 95% CI=1.22-9.17; P=0.04, OR=6.00; 95% CI=1.73-52.33, respectively). The best evidence for association in the trios was obtained for a haplotype composed of risk alleles of markers rs4618569 and rs2267641 (P=0.0006). There was an age-dependent enrichment of rs4618569 T allele and rs2267641 C allele in early-onset affected individuals. In conclusion, we propose DDR1 as a susceptibility gene for vitiligo, possibly implicating a defective cell adhesion in vitiligo pathogenesis.

- Abstract
Background: Leprosy is a chronic infectious disease that affects 250,000 new individuals/year worldwide. Genetic analysis has been successfully applied to the identification of host genetic factors affecting susceptibility to leprosy; however, a consensus regarding its mode of inheritance is yet to be achieved., Methods: We conducted a complex segregation analysis (CSA) on leprosy using data from the Prata Colony, an isolated, highly endemic former leprosy community located at the outskirts of the Brazilian Amazon. The colony offers large multiplex, multigenerational pedigrees composed mainly by descendents of a small number of original leprosy-affected families. Our enrollment strategy was complete ascertainment leading to the inclusion of the whole colony (2005 individuals, 225 of whom were affected) distributed in 112 pedigrees. CSA was performed using REGRESS software., Results: CSA identified a best-fit codominant model, with a major gene accounting for the entire familial effect observed. The frequency of predisposing allele was estimated at 0.22. Penetrance for homozygous individuals for the predisposing allele >30 years old ranged from 56% to 85%, depending on sex., Conclusions: A strong major gene effect in the isolated, hyperendemic Prata Colony indicates enrichment of genetic risk factors, suggesting a population particularly suitable for leprosy gene identification studies.

- Abstract
Objective: The present study evaluated the association between lactotransferrin (LTF) gene polymorphism (exon 2, A/G, Lys/Arg) and dental caries., Material and Methods: A convenience sample of 110 individuals, 12 years old, was divided into: group 1, 48 individuals without caries experience (DMFT=0), and group 2, 62 subjects with caries experience (DMFT>or=1). DNA was obtained from a mouthwash with 3% glucose solution, followed by a scrapping of the oral mucosa. After DNA purification, polymerase chain reaction (PCR), single strand conformation polymorphism (SSCP) was performed to access the study polymorphism. The LTF A/G (Lys/Arg) polymorphism had been previously reported as located in exon 1., Results: Allele 1 of the study polymorphism was associated with low DMFT index and showed a protective effect against caries experience (OR=0.16, IC=0.03-0.76, p=0.01)., Conclusions: Lactotransferrin A/G (exon 2, Lys/Arg) polymorphism was associated with susceptibility to dental caries in 12-year-old students.

- Abstract
Objective: We examined the potential for research using administrative databases containing dentists' claims to identify both the type of health services research questions addressed and the strength of the evidence that is achieved in such studies., Methods: We searched Medline (1966 to March, 2003), retrieved additional reports from personal files, reviewed the literature cited in the relevant articles and conducted electronic searches on investigators' surnames. Information from relevant articles was abstracted into tables and the strength of the evidence for each was classified., Results: Thirty-eight studies met our inclusion criteria. Researchers have used administrative databases of dental records to examine provider practices, the longevity or consequences of dental interventions, the prevalence of dental conditions, and patient factors that determined care, and to establish quality assurance criteria or standards of care. The strongest designs were prospective or case-control (Level II-2)., Conclusion: Studies analyzing administrative databases have the advantage of size and economy but are subject to several threats to their validity and are seldom population-based. The strongest designs occurred with investigation of the longevity or consequences of care. Several studies demonstrated the benefit of linking the service data to patient or provider characteristics. The study of dentists' claims data appears under exploited, especially in the area of identifying and recommending changes in dental health care policies.
