Universal health coverage is a global target included in the United Nations Sustainable Development Goals agenda for 2030. Healthcare in Brazil has universal coverage through the Unified Health System (SUS), which guarantees health as basic right to the Brazilian population. Considering the principles of SUS, public oral healthcare management is a huge challenge. Aim To identify good management practices for quality care adopted by local public oral healthcare managers and teams around Brazil. Methods This study was registered with PROSPERO (CRD42017051639). Five databases (PubMed, Embase, Web of Science, Scopus and Lilacs) as well as the reference lists and citations of the included publications were searched according to PRISMA guidelines. Results A total of 30,895 references were initially found, which were evaluated according to the defined eligibility criteria. Twenty qualitative studies, eight surveys and two mixed-model studies were selected. The practices (codes) were organized into three main groups (families), and the Frequency of the Effect Size (FES) of each code was calculated. Among the 20 codes identified, the most relevant ones were: Diagnosis and Health Planning (FES=80%) and Family Health Strategy (FES=66,7). The Intensity of the Effect Size of each study was also calculated to demonstrate the individual contribution of each study to the conclusions. Conclusion The evidence emerging from this review showed that healthcare diagnosis, planning, and performance based on the family health strategy principles were the most relevant practices adopted by public oral healthcare managers in Brazil. The widespread adoption of these practices could lead to improved oral healthcare provision and management in Brazil.

Abstract Prevention and health promotion are considered important strategies to control oral diseases. Dental caries is preventable disease and remains the most common chronic disease that affects mainly low income children and still considered the main cause of tooth loss in adulthood in Brazil. The aim of this study is to present a System Dynamics model (SDM) specifically developed with the Stella Architect software to estimate the cost and clinical hours required to control the evolution of dental caries in preschool children in Maringá, Brazil. Two main strategies to control caries were considered in the model: the application of fluoride varnish on teeth presenting white spots, and the use of Atraumatic Restorative Treatment (ART) in cavitated carious lesions without pulp involvement. The parameters used in the model were: number of people covered by a local oral health team = 4,000; number of children up to 5 years = 7% of the population; children’s decayed, missing, filled teeth (dmft) index = 2.4; time/cost of 4 applications of fluoride varnish = 5 minutes/US$ 0.716; and time/cost of each ART restoration = 15 minutes/US$ 1.475. The SDM generated an estimated total cost of US$698.00, and a total of 112 clinical hours to treat the population in question. The use of the SDM presented here has the potential to assist decision making by measuring the material and human resources required to prevent and control dental caries at an early age.

Resumo Introdução A solubilidade e sorção dos materiais restauradores são considerados fatores críticos, pois podem interferir na qualidade e durabilidade das restaurações. Objetivo Avaliar a solubilidade e sorção de água de alguns materiais restauradores. Material e método Foram confeccionados quatorze espécimes de cada um dos seguintes materiais: Equia® Forte, Z100, Fuji IX/ e Vidrion R, os quais foram levados a uma dessecadora e pesados diariamente até estabilização. Em seguida, foram inseridos em recipientes individuais contendo 40 mL de água destilada cada e divididos em dois grupos de acordo com o tempo de armazenagem: 7 ou 30 dias. Ao final de cada período, os espécimes foram retirados da água, pesados, levados à dessecadora e pesados novamente até estabilização. Os resultados foram analisados estatisticamente utilizando os testes ANOVA 2 critérios e Tukey. Resultado Com exceção do Equia® Forte e Z100, os demais materiais, apresentaram uma variação significativa da solubilidade ao longo do tempo. Quanto à sorção, observa-se que apenas o material Z100 não apresentou diferença significativa em relação ao tempo de armazenagem, mas, na comparação entre os materiais, todos apresentaram diferenças significativas em ambos os períodos. Conclusão Após os períodos de armazenagem de 7 e 30 dias em água, os materiais restauradores Equia® Forte e Z100 não apresentam variação significativa da solubilidade, sendo mais estáveis que os materiais Fuji IX e Vidrion R. Os materiais à base de ionômero de vidro, Equia® Forte, Fuji IX e Vidrion R, sofrem mais sorção em água quando comparados ao material Z100 em ambos os períodos.

Abstract Introduction The solubility and sorption parameters of restorative materials are considered critical factors since they may interfere with the quality and durability of restorations. Objective The aim of this study was to evaluate the solubility and water sorption of some restorative materials. Material and method Fourteen specimens were made (10.0 mm x 2.0 mm) of each of the following material: Equia® Forte, Z100, Fuji IX/ e Vidrion R, then taken to a desiccator and weighed daily until stabilized. They were then placed in individual containers with 40mL of distilled water each and divided into two groups according to the storage time: 7 or 30 days. At the end of each period, the specimens were removed from the water, weighed, taken to the desiccator and weighed again until stabilized. The results were analyzed statistically with two-way ANOVA and Tukey. Result Except for Equia® Forte and Z100, the other materials presented a significant variation of solubility over time. As for sorption, it was noticed that only Z100 presented no significant difference in relation to the storage time, but in comparison of the materials, all had significant differences in both 7 and 30 days periods. Conclusion After storage periods of 7 and 30 days in water, the restorative materials Equia® Forte and Z100 do not present significant variation of solubility, being more stable than the materials Fuji IX and Vidrion R. The glass ionomer-based materials, Equia® Forte, Fuji IX and Vidrion R, suffer more sorption in water when compared to Z100 material in both periods.

Resumo Dentre as abordagens minimamente invasivas atualmente disponíveis, o tratamento restaurador atraumático (ART) demonstra resultados promissores tanto na dentadura decídua quanto permanente. Objetivo Avaliar a sobrevivência de restaurações ART Classe I, em pré-escolares, com duas marcas brasileiras de cimentos de ionômeros de vidro (CIV) em comparação com um CIV de referência. Material e método Cavidades de 49 crianças pré-escolares (três a cinco anos de idade) com lesões cariosas nos dentes posteriores (N = 81) foram preenchidas por dois odontopediatras experientes, de acordo com a técnica ART. Os CIV brasileiros Maxxion-R (MR) e Vitro-Fil LC (VF) e o CIV de referência, Ketac-Molar (KM), foram inseridos em uma sequência pré-estabelecida aleatoriamente. As restaurações foram avaliadas após 6 e 12 meses por outro pesquisador. As pontuações 0 e 1 foram consideradas bem-sucedidas, enquanto as pontuações 3-9 foram classificadas como falhas. Foram aplicadas a análise de sobrevivência de Kaplan-Meier e o teste log-rank (p <0,05). Resultado Não foram observadas diferenças estatisticamente significativas nas taxas de sobrevivência dos CIV testados após 12 meses. Conclusão O desempenho clínico dos CIV brasileiros MR e VF, observado após 12 meses, sugere que estes podem ser uma alternativa para restaurações ART Classe I para proteger a esfoliação natural dos dentes decíduos. No entanto, até que sejam realizados estudos adicionais envolvendo um maior número de restaurações e períodos de acompanhamento mais longos, os CIV de referência, como o KM, devem continuar sendo o material de escolha para as restaurações ART.

Abstract Among the minimally invasive approaches available today, the atraumatic restorative treatment (ART) has demonstrated promising results both in the primary and permanent dentition. Objective To evaluate the survival of Class I ART restorations in preschoolers with two Brazilian brands of glass ionomer cements (GIC) in comparison with a reference GIC. Material and method The cavities of 49 preschool children (three to five years) with carious lesions in the posterior teeth (N=81) were filled by two experienced pediatric dentists according to the ART technique. The Brazilian GICs Maxxion-R (MR) and Vitro-Fil LC (VF), and the reference GIC Ketac-Molar (KM) were placed in a randomly pre-established sequence. Restorations were evaluated after 6 and 12 months by another investigator. Scores 0 and 1 were considered successful, while scores 3-9 were classified as failures. Kaplan-Meier survival analysis and the log-rank test were performed (p<0.05). Result No statistically significant differences in survival rates of the tested GIC were observed after 12 months. Conclusion The clinical performance the low-cost Brazilian GICs MR and VF observed after 12 months suggests that they may be an alternative for Class I ART restorations to safeguard the natural exfoliation of primary teeth. However, until further studies involving a larger number of restorations and longer follow-up periods are conducted, reference GIC such as KM should continue to be the material of choice for ART restorations.

Resumo Introdução O potencial erosivo das bebidas energéticas (BE) devido ao baixo pH e à presença de ácido cítrico pode estar relacionado ao aumento dos índices de erosão dental da população em geral e especialmente, nos jovens. Objetivo Verificar o pH e a titulação ácida de BE e a influência de uma marca de BE na microdureza superficial do esmalte. Material e método Dez amostras de BE de diferentes marcas comerciais foram selecionadas. O pH de dois lotes de cada BE foi analisado, com e sem gás. A titulação ácida foi realizada com a adição de alíquotas de NaOH, até atingir pH 7,0. Dezoito amostras de esmalte dental humano foram distribuídas aleatoriamente em três grupos (n = 6), Red Bull (RB), Red Light Bull (RBL) e água destilada (C), submetidas a um desafio ácido com a BE, seis vezes consecutivas, com intervalos de 12 horas, durante três dias. A microdureza Knoop foi medida antes e depois do desafio ácido. Resultado Todas as marcas de BE testadas apresentaram baixos níveis de pH, variando de 2,1 a 3,2. Em relação à titulação ácida, verificou-se que a quantidade de base necessária para promover a neutralização das soluções variou de 1200 μL a 3750 μL. Amostras de esmalte humano nos grupos RB e RBL submetidos ao desafio ácido apresentaram diminuição significativa da microdureza Knoop. Conclusão Todas as BE examinadas apresentaram baixo pH e alta titulação ácida e, portanto, potencial para promover perda mineral. As BE analisadas promoveram perdas minerais significativas na superfície do esmalte dental.

Abstract Introduction Energy drinks (ED) possess low pH and citric acid in their composition, making them potentially erosive beverages that can contribute to the high dental erosion rates found currently in the general population and also in young people. Objective To evaluate the mean pH and titratable acidity of commercial ED and the influence of a brand of ED on the superficial microhardness of human enamel. Material and method Ten commercial ED were selected and the pH of two lots of each ED with and without gas was obtained. Acid titration was conducted with the addition of NaOH aliquots until the pH 7 was reached. Eighteen human enamel specimens were allocated in three groups (N=6), Red Bull (RB), Red Bull Light (RBL) and distilled water (C), submitted to an acid challenge with the ED, six consecutive times, with 12 hours intervals, during three days. Knoop microhardness was measured before and after the acid challenge. Result All ED brands tested presented low pH levels ranging from 2.1 to 3.2. Regarding titratable acidity, it was found that the amount of base required promoting the neutralization of the solutions ranged from 1200μL to 3750μL. Samples of human enamel in the RB and RBL groups submitted to the acid challenge presented significantly decreased Knoop microhardness when compared with the group C. Conclusion All ED examined have potential to promote mineral loss due to the low pH and high titratable acidity. The ED analyzed promoted significant mineral losses on the dental enamel surface.

Current Brazilian law regarding water fluoridation classification is dichotomous with respect to the risks of and benefits for oral diseases, and fluoride (F) concentrations less than 0.6 or above 0.8 mg F/L are considered outside the normal limits. Thus, the law does not consider that both caries and fluorosis are dependent on the dosage and duration of fluoride exposure because they are both chronic diseases. Therefore, this study evaluated the quality of water fluoridation in Maringá, PR, Brazil, considering a new classification for the concentration of F in water the supply, based on the anticaries benefit and risk of fluorosis (CECOL/USP, 2011). Water samples (n = 325) were collected monthly over one year from 28 distribution water networks: 20 from treatment plants and 8 from artesian wells. F concentrations were determined using a specific ion electrode. The average F concentration was 0.77 mg F/L (ppm F), ranging from 0.44 to 1.22 mg F/L. Considering all of the water samples analyzed, 83.7% of them presented from 0.55 to 0.84 mg F/L, and according to the new classification used, they would provide maximum anticaries benefit with a low risk of fluorosis. This percentage was lower (75.4%) in the water samples supplied from artesian wells than from those distributed by the treatment plant (86%). In conclusion, based on the new classification of water F concentrations, the quality of water fluoridation in Maringá is adequate and is within the range of the best balance between risk and benefit.

OBJETIVO: Diagnosticar a prevalência de restaurações de amálgama e resina composta realizadas por profissionais no serviço público e estudantes universitários de um município do noroeste do estado do Paraná. MÉTODOS: Foram selecionadas aleatoriamente dez unidades básicas de saúde, das quais foram consultados 500 prontuários de pacientes com 18 a 50 anos, de ambos os sexos. Para analisar a prevalência das restaurações realizadas pelos estudantes, aplicou-se um questionário aos estudantes do quarto e quinto ano contendo perguntas relativas ao número de restaurações e tipo de material utilizado nas atividades clínicas intramuros. RESULTADOS: Nas unidades básicas de saúde, 66% das restaurações foram feitas com amálgama e 34% com resina composta. Na escola, os estudantes do quarto ano responderam que quando estavam no terceiro ano, de um total de 367 restaurações, 21,5% foram feitas com amálgama e 78,5% com resina. Para o grupo de estudantes do quinto ano, a porcentagem de dentes restaurados com amálgama foi de 14,3%, 12,0% e 10,2%, respectivamente, para quando estavam no 3º, 4º e 5º ano do curso. Os resultados obtidos revelaram que a indicação do material restaurador nos dois cenários é divergente. CONCLUSÃO: Nas unidades básicas de saúde a maioria das restaurações realizadas foi de amálgama enquanto na escola, a maior prevalência foi de resina composta. Deve-se refletir se a formação profissional tem desenvolvido adequadamente as competências necessárias para a tomada de decisão e o atendimento às necessidades da população.

OBJECTIVE: To diagnose the prevalence of amalgam and resin composite restorations performed by professionals in public service and university students in a municipality in the Northeast of the State of Paraná. METHODS: Ten basic health units were randomly selected, at which 500 clinical record charts of patients of both sexes aged from 18 to 50 years were consulted. To analyze the prevalence of restorations performed by students, a questionnaire was applied to 4th and 5th year students, containing questions relative to the number of restorations and type of material using in intramural clinical activities. RESULTS: In the basic health units, 66% of restorations were performed with amalgam, and 34% with resin composite. At the dental school, 4th year students responded that when they were in the 3rd year, out of a total of 367 restorations, 21.5% were performed with amalgam and 78.5% with resin composite. For the 5th year group of students, the percentage of teeth restored with amalgam was 14.3%, 12.0% and10.2%, when they were in the 3rd, 4the and 5th years of the course, respectively. The results obtained revealed that the indication of the restoration material differed in the two scenarios. CONCLUSION: In the basic health units, the majority of restorations were performed with amalgam, whereas at the dental school there was higher prevalence of resin composite restorations. One must reflect whether professional education has adequately developed the necessary competencies for decision making and meeting the needs of this population.

Objectives: This study evaluated the influence of different exposure times to saliva in situ in comparison with an antioxidant treatment on composite resin bond strength to human enamel restored after tooth bleaching. Material and Methods: Forty human teeth specimens measuring 5x5 mm were prepared and randomly allocated into 5 groups with 8 specimens each: Gct (control group, restored on unbleached enamel); Gbl (restored immediately after bleaching); Gsa (bleached, treated with 10% sodium ascorbate gel for 60 min and restored); G7d (bleached, exposed to saliva in situ for 7 days and restored); and G14d (bleached, exposed to saliva in situ for 14 days and restored). Restored samples were cut into 0.8 mm2 sticks that were tested in microtensile. Specimens were microscopically analyzed and failure modes were classified as adhesive, cohesive, or mixed. Pretest and cohesive failures were not considered in the statistical analysis, which was performed with one-way ANOVA and Tukey's post-hoc test (α=0.05), with the dental specimen considered as the experimental unit. Results: Mean bond strength results found for Gbl in comparison with Gct indicated that bleaching significantly reduced enamel adhesiveness (P<0.01). However, no statistically significant differences were found between Gct, Gsa and G7d (P>0.05). Bond strength found for G14d was significantly higher than for Gsa (P<0.01). Fractures modes were predominantly of a mixed type. Conclusions: Bonding strength to bleached enamel was immediately restored with the application of sodium ascorbate and exposure to human saliva in situ for at least 7 days. Best results were obtained with exposure to human saliva in situ for 14 days. Treatment with sodium ascorbate gel for 60 min may be recommended in cases patients cannot wait for at least 7 days for adhesive techniques to be performed.

INTRODUÇÃO: a superfície do côndilo da mandíbula é constituída por quatro camadas: uma externa (constituída de tecido conjuntivo denso), seguida pela camada de células indiferenciadas, cartilagem hialina e osso. Poucos estudos demonstraram o comportamento da cartilagem condilar quando a mandíbula é posicionada posteriormente, como na terapia para correção de Classe III funcional. OBJETIVO: o objetivo desse trabalho foi avaliar os aspectos morfológicos e histológicos do côndilo de ratos, em resposta ao posicionamento posterior da mandíbula. MÉTODOS: foram selecionados 30 ratos Wistar, machos, com cinco semanas de vida, aleatoriamente divididos em dois grupos: grupo controle (GC) e grupo experimental (GE), que recebeu dispositivos para induzir a retrusão mandibular. Os animais foram sacrificados após 7, 21 e 30 dias de experimento. Para a análise histológica, foi realizada a mensuração da espessura condilar total, incluindo as camadas proliferativa, seriada e hipertrófica, assim como cada camada separadamente, totalizando 30 medições para cada parâmetro, de cada animal. RESULTADOS: a maior diferença na espessura da cartilagem foi observada em 21 dias, apesar de serem verificados níveis diferentes nos demais períodos. Em GE, foi possível observar um aumento de 39,46% na camada total, representado pelo aumento na espessura das camadas hipertrófica (42,24%), seriada (46,92%) e proliferativa (17,70%). CONCLUSÕES: o reposicionamento posterior da mandíbula produziu uma série de respostas histológicas e morfológicas no côndilo, e sugerem a ocorrência de uma adaptação condilar e mandibular em ratos.

INTRODUCTION: The mandibular condylar surface is made up of four layers, i.e., an external layer composed of dense connective tissue, followed by a layer of undifferentiated cells, hyaline cartilage and bone. Few studies have demonstrated the behavior of the condylar cartilage when the mandible is positioned posteriorly, as in treatments for correcting functional Class III malocclusion. OBJECTIVE: The aim of this study was to assess the morphologic and histological aspects of rat condyles in response to posterior positioning of the mandible. METHODS: Thirty five-week-old male Wistar rats were selected and randomly divided into two groups: A control group (C) and an experimental group (E) which received devices for inducing mandibular retrusion. The animals were euthanized at time intervals of 7, 21 and 30 days after the experiment had began. For histological analysis, total condylar thickness was measured, including the proliferative, hyaline and hypertrophic layers, as well as each layer separately, totaling 30 measurements for each parameter of each animal. RESULTS: The greatest difference in cartilage thickness was observed in 21 days, although different levels were observed in the other periods. Group E showed an increase of 39.46% in the total layer, reflected by increases in the thickness of the hypertrophic (42.24%), hyaline (46.92%) and proliferative (17.70%) layers. CONCLUSIONS: Posteriorly repositioning the mandible produced a series of histological and morphological responses in the condyle, suggesting condylar and mandibular adaptation in rats.

The National Curricular Guidelines (NCGs) for undergraduate dental courses establish conceptual, philosophical and methodological elements in different practical scenarios aiming at changing the professional educational process through the development of competences and skills. As a result, professional training activities should be performed throughout the entire undergraduate course. The aim of this study was to report on activities performed during the Community Health Care Supervised Training Program at a nursery school by dental students from State University of Maringá. Students from the 3rd year were responsible for performing supervised toothbrushing, developing recreational-educational activities with the pupils, and providing oral health training to parents, caregivers and members of the Family Health Strategy (FHS) team; while students in the 4th year performed atraumatic restorative treatment (ATR) and, whenever necessary, applied sealant material to pupils' teeth. Undergraduates interacted directly with children, parents, teachers and the ESF team. By applying theory to their practice, students gained experience in team work. The six general competences and skills required by the NCGs for the health area courses were developed. The activities developed with the pupils demonstrated the importance of establishing of a relationship based on a multi-professional, interdisciplinary and holistic approach for the promotion of health in the community.

OBJETIVO: o objetivo deste trabalho foi avaliar, por microscopia eletrônica de varredura, a eficácia de dois discos abrasivos de silicone e óxido de alumínio para a remoção da resina remanescente após a descolagem de braquetes ortodônticos. MÉTODOS: foram utilizados 10 dentes bovinos selecionados aleatoriamente, sendo 2 para o grupo controle e os demais divididos em dois grupos, os quais receberam colagem de braquetes ortodônticos com resina ortodôntica Concise (3M). Os métodos de remoção da resina após a descolagem dos acessórios ortodônticos em apenas uma etapa foram: Grupo A - disco Optimize (TDV); e Grupo B - disco Onegloss (Shofu), empregados em baixa rotação. Após a remoção da resina remanescente pelos métodos mencionados, os dentes foram preparados para serem submetidos à análise em microscopia eletrônica de varredura, obtendo-se fotografias da superfície do esmalte com aumento de 50X. Seis examinadores avaliaram as fotografias seguindo a escala de avaliação de Zachrisson e Arthun (1979). RESULTADOS: no Grupo A, observou-se pequenos arranhões na superfície do esmalte, bem como pouco remanescente de resina em algumas das fotografias; enquanto, no Grupo B, observou-se maior lisura, pouco ou nenhum remanescente de resina e alguns riscos nas fotografias. Não houve diferença estatisticamente significativa entre os dois métodos avaliados e o grupo controle. CONCLUSÃO: os dois discos abrasivos mostraram-se eficientes para remoção da resina remanescente após a descolagem de braquete em única etapa.

OBJECTIVE: The aim of this study was to assess - using scanning electron microscopy (SEM) - the effectiveness of two abrasive discs, one made from silicon and one from aluminum oxide, in removing adhesive remnants (AR) after debonding orthodontic brackets. METHODS: Ten randomly selected bovine teeth were used, i.e., 2 in the control group, and the other 8 divided into two groups, which had orthodontic brackets bonded to their surface with Concise Orthodontic Adhesive (3M). The following methods were employed - in one single step - to remove AR after debracketing: Group A, Optimize discs (TDV) and Group B, Onegloss discs (Shofu), used at low speed. After removing the AR with the aforementioned methods, the teeth were prepared to undergo SEM analysis, and photographs were taken of the enamel surface with 50x magnification. Six examiners evaluated the photographs applying the Zachrisson and Årtun enamel surface index (ESI) system (1979). RESULTS: Group A exhibited minor scratches on the enamel surface as well as some AR in some of the photographs, while Group B showed a smoother surface, little or no AR and some abrasion marks in the photographs. No statistically significant differences were found between the two methods and the control group. CONCLUSIONS: The two abrasive discs were effective in removing the AR after bracket debonding in one single step.
