Changes in Use of Prenatal Dental Care After Brazil's Incentive Policy.

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.

Splinting in the management of dental trauma in the primary dentition: a systematic review.

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.

Trajectories of Sugar Consumption and Dental Caries in Early Childhood.

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.

A scoping review of root canal revascularization: relevant aspects for clinical success and tissue formation.

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.
