RESUMO
In 2020, the Brazilian federal government launched the "Prevent Brazil" program to incentivize cities to improve their performance across 7 health care indicators, including prenatal dental care. Our study examines the impact of this policy on the use of oral health care among pregnant women in Brazil. We used a series of cross-sectional data from the Brazilian Public Health System from 2018 to 2023. We linked publicly available data from the Brazilian Ministry of Health and the Brazilian Institute of Geography and Statistics. Our outcome was the proportion of pregnant women receiving prenatal care who had at least 1 dental visit during the past year. Covariates included city-level socioeconomic (income and literacy), demographic (gender, race, and urban areas), and workforce variables (number of dentists working in the public health system per city/year). We estimated the impact of the policy on prenatal dental visits nationwide and stratified by geographic region using interrupted time-series analysis. Our analyses included 99.9% of all Brazilian cities (n = 5,562). The use of oral health care among pregnant women increased from 15% in 2018 to 69% in 2023. Adjusted estimates show that, after initiation of the Prevent Brazil, dental care use among pregnant women increased nationally at a rate of 4.6 percentage points per 4-mo period (95% confidence interval [CI] 4.5; 4.7). The policy's largest impact was in the North and Northeast regions, which have the lowest socioeconomic profiles (adjusted time-series rate 5.7 [95% CI 5.3; 6.1] and 5.2 [5.0; 5.4] percent points, respectively). Our findings support the positive impact of the Prevent Brazil policy on prenatal dental care in Brazil. The policy was associated with a countrywide improvement in prenatal dental care use, with a greater impact in socioeconomically disadvantaged regions.
RESUMO
We applied a structural intersectionality approach to cross-sectionally examine the relationships between macro-level systems of oppression, their intersections, and access to oral care in the United States. Whether and the extent to which the provision of government-funded dental services attenuates the emerging patterns of associations was also assessed in the study. To accomplish these objectives, individual-level information from over 300,000 respondents of the 2010 US Behavioral Risk Factor Surveillance System was linked with state-level data for 2000 and 2010 on structural racism, structural sexism, and income inequality, as provided by Homan et al. Using multilevel models, we investigated the relationships between systems of oppression and restricted access to oral health services among respondents at the intersections of race, gender, and poverty. The degree to which extended provision of government-funded dental services weakens the observed associations was determined in models stratified by state-level coverage of oral care. Our analyses bring to the fore intersectional groups (e.g., non-Hispanic Black women and men below the poverty line) with the highest odds of not seeing a dentist in the previous year. We also show that residing in states where high levels of structural sexism and income inequality intersect was associated with 1.3 greater odds (95% confidence interval, 1.1-1.5) of not accessing dental services in the 12 mo preceding the survey. Stratified analyses demonstrated that a more extensive provision of government-funded dental services attenuates associations between structural oppressions and restricted access to oral health care. On the basis of these and other findings, we urge researchers and health care planners to increase access to dental services in more effective and inclusive ways. Most important, we show that counteracting structural drivers of inequities in dental services access entails providing dental care for all.

PURPOSE: The purpose of this study was to gather existing data on the efficacy of tooth splinting (TS) in patients with traumatized primary teeth, evaluating their overall prognosis and reported complications. METHODS: Electronic searches were performed in seven databases up to Februray/2023. Clinical studies published in the last two decades and presenting the following characteristics were included: (a) reporting on children with traumatized primary teeth; (b) describing the efficacy of splinting those teeth. Studies describing imobilization of dental avulsion were excluded. RESULTS: A total of 163 potentially relevant studies were initially found. After title/abstract screening, and full-text evaluation, three retrospective studies with moderate to high risk of bias were included. The studies described the outcomes of TS in primary teeth with luxation (intrusion, extrusion, lateral displacement), intra-alveolar root fracture, and/or alveolar fracture. High clinical success rate was observed for teeth with root fracture. Benefits of spliting teeth with lateral luxation were not identified, although it may be a reccomended approach. No study was found evaluating TS for alveolar fracture. CONCLUSION: Based on a low level of evidence, the findings highlight a better clinical success rate of the use of TS in the management of deciduous teeth with root fractures.

This study verifies the association between the trajectory of sugar consumption and dental caries in the 2015 Pelotas Birth Cohort in Pelotas, Brazil. It was conducted with data from the follow-ups at 3, 12, 24, and 48 mo from the 2015 Birth Cohort, which included 4,275 children born alive in hospitals in Pelotas. Data collection included standardized questionnaires for first caregivers applied by trained interviewers at all follow-ups. Exposure was the trajectory of sugar consumption from 3 to 48 mo (always low, always intermediate, increasing, and always high), obtained by group-based trajectory modeling. The outcome of this study was dental caries, obtained through clinical examination performed by calibrated dentists at 48 mo of age. Socioeconomic conditions and oral health instruction from a health professional during the first 4 y of life were included in the analysis as potential confounders. Prevalence ratios and their 95% confidence intervals were provided from generalized estimating equations with a log-Poisson with robust variance specification. In total, 3,654 (91.1%) children participated in the survey at 48 mo, and 2,806 children had complete data for the analyzes performed. Of these, 1,012 (36.1%; 95% confidence interval [CI], 34.3-37.8) experienced caries, and 723 (25.8%; 95% CI, 24.2-27.4) had cavitated caries. Regarding cavitated caries, the prevalence was 1.48 times higher in the group with increasing sugar consumption than children with always low consumption. There is an association between the trajectory of sugar consumption and dental caries at 48 mo. Children with increasing and always high sugar consumption have the highest prevalence of caries.

The aim of this scoping study was to evaluate the survival rate and nature of tissue formed inside root canals of human immature permanent teeth with necrotic pulps (NIPT) under root canal revascularization (RCR). The search was performed in SciVerse Scopus®, PubMed/MEDLINE, Web of Science®, BIREME and in the grey literature up to November 2015. The keywords were selected using MeSH terms and DECs. Two independent reviewers scrutinized the records obtained considering specific inclusion criteria. The included studies were evaluated in accordance with a modified Arksey and O' Malley's framework. From 375 studies that were evaluated, 75 were included. A total of 367 NIPT were submitted to RCR, from which only 21 needed further endodontic treatment. The weighted mean follow-up time was 17.6 months. The data were derived mainly from case reports (69%) or small case series (15%). NaOCl [0.5-6%] was applied as the disinfecting solution in almost all studies. Triple antibiotic paste was as effective as Ca(OH)2 as on intracanal medicament. De novo tissue was cementum and poorly mineralized bone positive to bone sialoprotein (BSP) but negative to dentine sialoprotein (DSP). Failures were associated mainly with reinfection of the root canal. The majority of included studies reported a significant increase in both root length and width. However, as most of these data came from case reports, they must be interpreted with care, as most were focused on treatment successes (not failures). Therefore, well-designed randomized controlled trials comparing RCR with available apexification treatments are needed to address this gap in the literature.

Chronic periodontal disease (CPD) is a highly prevalent, multifactorial, bacterially induced inflammatory disease, characterized by pathologic loss of periodontal attachment and alveolar bone with onset mostly in adulthood. While cross-sectional data have demonstrated significant associations between adverse socioeconomic position (SEP) and poor periodontal conditions, there is a gap in the literature on the understanding of how SEPs in different life stages impact on the occurrence of this disease later on. Life-course epidemiology offers different theoretical models to study the pathway of health and illness during the lifespan, and the hypothesis of the present study is that the relationship between SEP and CPD can be explained based on different life-course epidemiology theories: (a) critical period model; (b) critical period with modifier effect model; (c) accumulation of risk model; (d) chain-of-risk model. Under the first theoretical model, the association between SEP and CPD may be explained by an inflammatory hypothesis, considering that childhood adverse socioeconomic backgrounds alter the immunoinflammatory response that leads to disease in adulthood regardless of conditions later in life. The second model postulates that the early life SEP modifies the host immunoinflammatory response, and the risk of disease will be modified over the life-course by socio-behavioural influences. The third, "accumulation of risk model", may explain such relationship taking into account exposures during different periods of life. However, this model does not consider the moment when the exposure occurred, only taking into consideration the number of episodes during the life cycle. Finally, the potential explanation to the role of socioeconomic position on chronic periodontal disease, using a chain-of-risk model, is that early low SEP may cause social stress related to social hierarchies, what may, in turn, trigger endocrine, neural and immune changes, that reflect on elevated levels of cytokines, consequently turning these individuals more likely to develop periodontal disease. To summarize, this paper suggests potential explanations of the relationship between SEP during the lifespan and the occurrence of chronic periodontal disease in adult life, under a life-course framework. Longitudinal studies focusing on such relationship should be conducted, aiming to provide evidence regarding the hypotheses here called in question.
