Association of Oral Health-Related Quality of Life with the Longevity of ART-Restorations in Children

ABSTRACT Objective: To evaluate the association of oral health-related quality of life (OHRQoL) with the longevity of ART-restorations in children after 18 months. Material and Methods: A longitudinal clinical study with 62 six- to seven-year-old children, both genders, 31 of whom underwent four weeks of oral health education strategy (OHES) followed by ART (GOHES+ART) and the others only ART (GART). The Brazilian short-version of the Child Perceptions Questionnaire (16-CPQ8-10) was used to evaluate the OHRQoL and the perception of change in oral health was assessed by a single question. Data was analyzed using Mann-Whitney, Wilcoxon and Friedman's tests. Results: After 18 months, GOHES+ART reported a greater impairment on OHRQoL, mainly in oral symptoms domain (p<0.05). In this period, greater impairment of oral symptoms was reported in children with failed restorations and with treatment considered to have a minor failure (p<0.05). In inter-group analysis, the GOHES+ART, with 2 to 4 restorations, Class I, of small size, located in the upper arch and with a smaller failure, reported more oral symptoms than the GART. Conclusion: In the long-term, children submitted to OHES followed by ART reported more oral symptoms. Factors such as number, class, size and location of the restorations need to be considered for the implementation of an efficient and effective oral health program, as well as for greater longevity of ART-restorations.

Manejo de cárie radicular: um guia para o dentista brasileiro baseado na tradução e adaptação cultural do consenso internacional/ORCA E EFCD / Management of root caries: a guide for the Brazilian dentist based on the translation and cultural adaptation of the international consensus/ORCA and EFCD

Objetivo: A cárie radicular é um problema da Odontologia moderna, porém é notável a falta de diretrizes sobre o seu manejo. Objetivamos elaborar e adaptar um guia a partir da tradução das recomendações do consenso in-ternacional European Organization for Caries Research (ORCA) e European Federation of Conservative Dentistry (EFCD) para as tomadas de decisão clínica na intervenção do processo de cárie na pessoa idosa, com foco na cárie radicular. Materiais e métodos: O protocolo de tradução das recomendações do consenso internacional consistiu nas etapas: (1) tradução inicial, (2) síntese da tradução, (3) retradução, (4) revisão por comitê de especialistas, com adaptação cultural. A partir da tradução, foi desenvolvido um guia com diretrizes para tratamento de cárie radicular no Brasil. Resultados: Para prevenção de novas lesões é recomendada a escovação diária com dentifrício >1.500ppm/F. Dentifrícios com 5.000ppm/F ou vernizes (>20.000ppm/F) podem ser indicados para paralisar lesões radiculares ativas e para prevenção em pessoas idosas com alta suscetibilidade à cárie radicular, e o Diamino Fluoreto de Prata (>30%) para paralisar lesões ativas. Intervenções invasi-vas diretas são indicadas dependendo da situação clínica. Discussão: Nota-se uma falta de interesse em estudos primários sobre tratamentos para cárie radicular, criando assim uma lacuna em relação ao seu manejo, que reflete no nível de evidência detectado pelo consenso. Conclusão: Guias clíni-cos são importantes para reduzir a lacuna entre a pesquisa e a prática clínica. Essa tradução para o português facilitará o acesso dos dentistas bra-sileiros em relação a evidência consolidada até o momento para o manejo de cárie radicular.

Aim: Root caries are a problem in modern dentistry, but the lack of guidelines regarding their management is notable. We aim to develop and adapt a guide based on the translation of the recommendations of the international consensus as outlined by the European Organization for Caries Research (ORCA) and the European Federation of Conservative Dentistry (EFCD) for clinical decision-making in the intervention of the caries process in the elderly, with a focus on root caries. Materials and methods: The protocol for translating the recommendations of the international consensus consisted of the following steps: (1) initial translation, (2) synthesis of the translation, (3) back-translation, (4) review by an expert committee with cultural adaptation. Based on the translation, a guide was developed with guidelines for the treatment of root caries in Brazil. Results: To prevent new lesions, daily brushing with toothpaste >1,500ppm/F is recommended. Toothpaste with 5,000ppm/F or varnishes (>20,000ppm/F) may be recommended to paralyze active root lesions and for prevention in elderly people with high susceptibility to root caries, and Silver Diamine Fluoride (>30%) to paralyze active lesions. Direct invasive interventions are indicated depending on the clinical situation. Discussion: There is a lack of interest in primary studies on treatments for root caries, thus creating a gap in relation to its management, which is reflected by the level of evidence detected in the consensus. Conclusion: Clinical guidelines are important to reduce the gap between research and clinical practice. This translation into Portuguese will facilitate access by Brazilian dentists to the consolidated evidence gathered to date for the management of root caries.

A systematic review of randomized controlled trials on survival rate of atraumatic restorative treatment compared with conventional treatment on primary dentition

Background: In this COVID era, it's critical to promote nonaerosol procedures. Atraumatic restorative treatment (ART) is one of them, and it's particularly effective in children for lowering anxiety, enhancing dental health, and giving restorative care. Aim: The aim of this study was to assess the survival rate of ART compared with conventional treatment procedures in primary dentition. Materials and Methods: The review was done in accordance with the Preferred Reporting Items for Systematic reviews and Meta-analysis statement and is been registered in PROSPERO (CRD42021213729). The studies included comprised clinical investigations with randomized controlled trials (RCTs) which compared the survival rate of ART and conventional restorative treatments using the same or different restorative materials to treat carious lesion. RCTs in which ART was compared with conventional treatment on patients in the age group of 6–10 years with minimum follow-up of 6 months. Studies available as open access and free full text in PubMed, DOAJ, and Google Scholar databases, and published in English Language only were included in the study. Cochrane's collaboration tool for RCTs was used for the assessment of risk of bias. Results: The survival rate of single surface and multiple surface in primary dentition treated according to the ART compared with conventional treatment was found to be similar. Conclusion: The ART approach is equally helpful in managing dental caries in children and this method may be considered a useful intervention in clinical practice to enhance the dental health of children.

ART restorations for occluso-proximal cavities in primary molars: a two-year survival and cost analysis of an RCT comparing two GIC brands

Abstract There are many glass ionomer cements available on the Brazilian market for Atraumatic Restorative Treatment (ART), however, there is still a gap in the literature regarding their cost-effectiveness. Objectives To evaluate the influence of restorative materials (Ketac Molar, 3M ESPE; and Vitro Molar, Nova DFL) in the two-year survival rate and cost-effectiveness of occluso-proximal ART restorations in primary molars. Methodology A total of 117 children (aged four to eight years) with at least one occluso-proximal carious lesion in primary molars were selected and randomly divided in treatment groups (KM or VM) in this parallel randomized controlled trial. Treatments followed ART premises and were conducted in public schools by trained operators in Barueri, Brazil. A trained, calibrated, and blinded examiner performed the evaluations after two, six, 12, and 24 months (k=0.92). Kaplan-Meier survival analysis was used to estimate restoration survival and Cox regression was used to test the association with clinical factors (α=5%). For cost analysis, material and professional costs were considered. Monte Carlo analysis was used to generate a cost-effectiveness plane and bootstrapping was used to compare material costs over the years. Results The overall survival rate was 36.9% after two years (48.6% for KM and 25.4% for VM). Restorations with VM failed more than those with KM (HR=1.70; 95% CI=1.06-2.73; p=0.027). VM presented lower initial cost, but no difference was observed between groups considering the two-year incremental cost. Conclusion After a two-year evaluation, KM proved to be a better option than VM for occluso-proximal ART restorations in primary molars. ClinicalTrials.gov: NCT02267720

Restorative treatment in patient with Williams Syndrome: case report / Tratamento restaurador em paciente com Síndrome de Williams: relato de caso

ABSTRACT In Dentistry, any user with one or more limitations, of temporary or permanent mental nature, of physical, sensory, emotional or medical growth, is considered to be a Patient with Special Needs, preventing him from being subjected to a conventional dental situation. These patients form a group which may be considered at high risk for the development of oral diseases, according to the kind of pathogen. Among them, is the Williams-Beuren Syndrome, a rare congenital disease with cardiovascular involvement, mental retardation, dysmorphic face, idiopathic hypercalcemia, musculoskeletal problems, dental and growth anomalies. Familial and sporadic cases are thought to result from deletion of genetic material from adjacent genes located on the long arm of chromosome 7. This article reports a clinical case involving a four-year-old boy with Williams-Beuren Syndrome, referred to the clinic of the Specialization Course for Patients with Special Needs, at the São Leopoldo Mandic Dental Research Center, Campinas (SP). As the patient was resistant to dental care, in order to reduce anxiety and increase collaboration in clinical sessions, the Hixizine® medication was administered. For atraumatic restorative treatment and restorations, the following materials were used: Cleanjoy®, Futurabond DC®, Ionofil Plus® Grandioso®, Grandio® and Profluorid®. As result, it was possible to reach a level of excellence using the indicated materials and specific protocols. Based on this work and the lived experience, it can be observed that these patients can receive welcoming dental care in specialized clinics.

RESUMO Na Odontologia é considerado Paciente com Necessidades Especiais todo usuário que apresenta uma ou mais limitações, temporárias ou permanentes, de ordem mental, física, sensorial, emocional, de crescimento ou médica, que o impeça de ser submetido a uma situação odontológica convencional. Esses pacientes formam um grupo que pode ser considerado de alto risco para o desenvolvimento de doenças bucais, de acordo com o tipo de patogenia. Dentre elas, tem-se a Síndrome de Williams-Beuren, uma desordem congênita rara com envolvimento cardiovascular, retardo mental, face dismórfica, hipercalcemia idiopática, problemas musculoesqueléticos, anomalias dentárias e de crescimento. Os casos são hereditários ou esporádicos e a causa está na concepção com a deleção no braço longo do cromossomo 7. Este artigo relata um caso clínico envolvendo um menino de quatro anos, portador da síndrome, encaminhado para atendimento na Clínica do Curso de Especialização em Pacientes com Necessidades Especiais do Centro de Pesquisas Odontológicas São Leopoldo Mandic, Campinas (SP). Como o paciente apresentava resistência ao atendimento odontológico, com o objetivo de diminuir a ansiedade e aumentar a colaboração, nas sessões de atendimento foi administrado o medicamento Hixizine®. Para o tratamento restaurador atraumático e restaurações estéticas utilizou-se os seguintes materiais: Cleanjoy®, Futurabond DC®, Ionofil Plus®, Grandioso®, Grandio® e Profluorid®. Como resultado, foi possível atingir grau de excelência utilizando os materiais indicados e protocolos específicos. Mediante o caso relatado e frente à experiência vivenciada, pode-se perceber que esses pacientes podem receber um atendimento odontológico acolhedor nas clínicas especializadas.

EquiaFil achieved the second lowest efficacy, slightly higher than ChemFil Rock.Conclusion: Restorations with Fuji IX, Ketac Molar, and ChemFlex showed high success rates over the ART evaluation time.

Adherence to the CONSORT statement of randomized clinical trials on ART restorations in children: current status and reporting characteristics

Abstract: Appropriate research reports are important to facilitate the evaluation of studies and the decision-making by dentists and policymakers. This meta-research study assessed the conformity of randomized clinical trials (RCTs) on atraumatic restorative treatment (ART) restorations with the CONSORT recommendations and their risk of bias (RoB). Cochrane Library, MEDLINE, BBO, LILACS, Scopus, and Web of Science databases were searched from April 2019 to June 2021 for RCTs that assessed the longevity of ART restorations in children. A specific tool was used to assess adherence to the CONSORT recommendations; RoB was evaluated with the Cochrane risk-of-bias tool. Descriptive analyses included the number of studies by journal, follow-up period, country, and quality assessments. A total of 2,181 papers were retrieved and 36 of them were analyzed qualitatively. The overall CONSORT mean score (CONms) was 22.52 ± 6.17 out of 32 points. The best described items were intervention and outcomes, whereas allocation concealment was described in only 22% of the papers. Significant differences in CONms were detected in the analysis by country and publication dates. High CONms were observed in recently published papers (26.7 ± 3.1) when compared to first ART studies (18.1 ± 4.6; p < 0.001). RoB was low in four studies, unclear in 11, and high in 21. Adherence of the papers to the CONSORT recommendations was not fully achieved and most of the papers had unclear and high RoB (PROSPERO registration #CRD42020201460).

Bone formation in sinus augmentation with different xenograft particle sizes: systematic review and meta-analysis / Formação óssea em levantamento de seio maxilar com diferentes tamanhos de partículas de enxerto xenográfico: revisão sistemática e meta-análise

ABSTRACT The commercial bovine bone mineral most commonly used is available in two particle sizes and studies have demonstrated contradictory results regarding bone formation volume using small or large particles. The aim of this systematic review and meta-analysis was to compare the bone formation volume and residual bovine bone volume in sinus floor augmentation using small and large particles. The following outcome measures were assessed: bone formation volume (%) and residual bovine bone particles volume (%) assessed by histomorphometric analysis. The initial screening resulted in 236 records. After removal of duplicated articles and analysis of titles, abstracts and full texts, three articles were included in the meta-analysis. The bone formation volume and residual bovine bone volume did not differ between small and large particles, with low heterogeneity of studies. The particle size of bovine bone mineral did not influence bone formation percentage; small and large particles of bovine bone graft presented similar residual bone mineral; more randomized clinical trials should be performed to completely confirm that bovine bone mineral particle size does not affect the result of sinus floor augmentation.

RESUMO O enxerto ósseo bovino comercial mais comumente utilizado está disponível em dois tamanhos de partícula, que tem demonstrado resultados contraditórios em relação à formação óssea usando partículas pequenas ou grandes. O objetivo desta revisão sistemática e meta-análise é comparar o volume de formação óssea e o volume de enxerto residual em levantamento de seio usando partículas pequenas e grandes. Os seguintes dados foram comparados: volume de formação óssea (%) e volume residual de partículas de enxerto (%) dados por análise histomorfométrica. A seleção inicial resultou em 236 artigos. Após remoção de artigos duplicados e análise dos títulos, resumos e textos completos, três artigos foram incluídos na meta-análise. Os volumes de formação óssea e de enxerto residual não diferenciam entre os tamanhos de partícula pequeno e grande, com baixa heterogeneidade dos artigos. O tamanho de partícula de enxerto ósseo bovino não influencia o percentual de formação óssea; partículas de enxerto ósseo bovino pequenas e grandes apresentaram enxerto residual similar; mais ensaios clínicos randomizados deveriam ser realizados para confirmar que o tamanho de partícula de enxerto não afeta os resultados de levantamento de seio maxilar.

Aesthetic-functional rehabilitation of deciduous anterior teeth without removal of carious tissue: series of clinical cases / Reabilitação estético-funcional em dentes anteriores decíduos sem remoção de tecido cariado: série de casos clínicos

ABSTRACT The treatment of cavity carious lesions in anterior deciduous teeth is a frequent demand in the pediatric dentistry clinic, since the control of the disease in early childhood still presents itself as an inter-factor challenge in child health care. While the scientific evidence on the minimally invasive principles of approach in Dentistry is presented at an increasing level, the alternatives for restorative treatment in anterior deciduous teeth still face the low availability of reports that associate minimal intervention with the aesthetic needs inherent to the treatment. Thus, this article presents a series of cases in which direct restorations in composite resin, without removing carious tissue using polyvinyl matrices, were treatment alternatives for moderate and severe caries lesions in anterior deciduous teeth. It was observed, therefore, that the use of this artifact helped the rehabilitation of compromised dental elements with speed and satisfactory 50 result, suggesting that this is an appropriate approach for application in Pediatric Dentistry, 51 since it offers resistance, durability, besides providing aesthetics and functionality, it presents lower cost and agility as it eliminates the laboratory phase.

RESUMO O tratamento de lesões cavitadas de cárie em dentes decíduos anteriores é uma demanda frequente na clínica de odontopediatria, visto que o controle da doença na primeira infância ainda se apresenta como um desafio interfatorial nos cuidados em saúde infantil. Enquanto a evidência científica nos princípios minimamente invasivos de abordagem em Odontologia apresenta-se em nível crescente, as alternativas para tratamento restaurador em dentes decíduos anteriores ainda esbarram na baixa disponibilidade de relatos que associem a mínima intervenção às necessidades estéticas inerentes ao tratamento. Assim, este artigo apresenta uma série de casos em que as restaurações diretas em resina composta, sem a remoção de tecido cariado utilizando matrizes de polivinila foram alternativas de tratamento para lesões de cárie moderadas e severas em dentes decíduos anteriores. Observou-se que o uso desse artefato auxiliou a reabilitação dos elementos dentários comprometidos com rapidez e resultado satisfatório, sugerindo que essa é uma abordagem adequada para aplicação em Odontopediatria, já que oferece resistência, durabilidade, além de proporcionar estética e funcionalidade, apresenta menor custo e agilidade na medida que dispensa a fase laboratorial.

Survival of atraumatic restorative treatment restorations in the elderly patients: a systematic review

Abstract: This study aimed to assess the survival of glass ionomer cement (GIC) restorations performed using the atraumatic restorative treatment (ART) in elderly patients. The systematic review protocol was registered in the PROSPERO database. The records were searched until August 2020 in eight electronic bibliographic databases, and included randomized and non-randomized clinical trials and observational studies, with no restrictions on the language or year of publication. Study selection and data extraction were performed independently by two reviewers. Data were extracted, summarized, collected for qualitative analysis, and evaluated for individual risk of bias using the Joanna Briggs Institute's Critical Appraisal Tool. The literature search retrieved 5,186 records; however, only seven studies fulfilled the eligibility criteria and were included. The studies were published between 2002 and 2019. A total of 1,239 restorations were investigated at intervals of 6, 12, 24, and 60 months of follow-up. Some studies had a low risk of bias, while others had moderate and high risk of bias. In general, GIC restorations placed using ART were considered satisfactory. The 6-month, 12-month, and 24-month survival rates ranged from 81.3% to 97.2%, 72.2% to 94%, and 63% to 87%, respectively; additionally, the survival rate for the longest follow-up period (60 months) was 85%. Given the best evidence-based information regarding caries removal, we highlight the need to provide a conservative and effective technique for use in elderly patients. ART is a promising and viable alternative that guarantees the survival of restorations in elderly patients.

A prospective and randomized clinical trial evaluating the effectiveness of ART restorations with high-viscosity glass-ionomer cement versus conventional restorations with resin composite in Class II cavities of permanent teeth: two-year follow-up

Abstract Objective To compare the effectiveness of ART restorations using High Viscosity Glass-ionomer cement (HVGIC) with conventional restorations using resin composite in Class II cavities of permanent teeth, in a 2-year follow-up. Methodology Seventy-seven restorations were made with each restorative material, Equia Fil-GC Corporation (ART restorations) and Z350-3M (conventional restoration), in 54 participants in this parallel and randomized clinical trial. Restorations were evaluated at 6 months, 1 and 2 years using the ART and the modified United States Public Health Service (USPHS) criteria. Chi-square test and Survival Analysis (p<0.05) were used for statistical analysis. Results The success rates for ART restorations were 98.7% (6 months) and 95.8% (1 year) for both criteria. At 2 years, success rate was 92% and 90.3% when scored by the modified USPHS and ART criteria (p=0.466), respectively. The success rates for conventional restorations were 100% (6 months), 98.7% (1 year) and 91.5% (2 years) for both assessment criteria. ART restorations presented a lower survival rate by the criterion of ART (83.7%) when compared to the modified USPHS criterion of (87.8%), after 2 years (p=0.051). The survival of conventional restorations was 90.7% for both evaluation criteria. Conclusion At the 2-years follow-up evaluation, no statistically significant difference was observed between the success rate of ART restorations with HVGIC compared to conventional restorations with resin composite in Class II cavities of permanent teeth.

Is it necessary to pre-treat Dentine before GIC Restorations? Evidence from an in Vitro Study / É necessário pré tratar a dentina antes das restaurações de CIV? Evidência de um estudo in vitro

ABSTRACT The aim of this study was to assess the influence of differentpretreatmentapproaches on glass ionomer cement (GIC)bond strength (BS) to dentine. Sixty bovine incisors wereallocated into six groups according to substrate - sound orcariesaffecteddentine; and substrate pretreatmentapproach -no conditioning (control), polyacrylic acid for 10 s andphosphoric acid for 7 s. Teeth in the cariesaffecteddentinegroup were previously submitted to cariogenic pHcyclingchallenge. After dentine pretreatment,according to experi mentalgroups, polyethylene tubes were placed on flat dentinesurfaces and filled with GIC. Teeth were stored in distilledwater for 24 h at 37 °C and then submitted to microshear test(0.5 mm/min). Failure pattern analysis was performed understereomicroscope (400x). Data were analysed using twowayANOVA and Tukey's test (α=5%). Statistically significantdifferences were found for the pretreatmentapproach,regardless of substrate (p<0.001). The polyacrylic acid groupand control group had similar BS values, and were both betterthan the phosphoric acid group. In general, GIC had betterbonding performance in sound dentine than in cariesaffecteddentine. In conclusion, dentine pretreatmentwith polyacrylicacid did not improve the performance of GIC restoration onclinically relevant substrates.

RESUMO O objetivo deste estudo foi avaliar a influência de diferentesprétratamentosna resistência de união (RU) de cimentos deionômero de vidro (CIV) a dentina. Sessenta incisivos bovinosforam alocados em 6 grupos de acordo com o substrato -hígido ou cariado; e com a abordagem de prétratamento-sem condicionamento (controle), ácido poliacrílico por 10 s, eácido fosfórico por 7 s. Os dentes pertencentes aos grupos dedentina cariada foram previamente submetidos ao desafiocariogênico por meio da ciclagem de pH. Após o prétratamentoda dentina, de acordo com os grupos experimentais,tubos de polietileno foram colocados sobre superfícies planas dedentina e preenchidos com CIV. Os dentes foram armazenadosem água destilada por 24 h a 37°C e então submetidos ao testede microcisalhamento (0,5 mm/min). A análise do padrão defratura foi realizada em estereomicroscópio (400x). Os dadosobtidos foram analisados usando ANOVA de dois fatores e testede Tukey (α=5%). Diferença estatisticamente significante foiencontrada para as diferentes abordagens de prétratamento,independente do substrato (pp<0,001). Aplicação de ácidopoliacrílico resultou em valores de RU similares aos do grupocontrole. Entretanto, ambos os grupos mostraram um melhordesempenho quando comparado a aplicação de ácidofosfórico. De forma geral, CIV apresentou melho5 desempenhoadesivo em dentina sadia quando comparada a dentinacariada. Em conclusão, o prétratamentoem dentina comácido poliacrílico não melhora o desempenho das restauraçõesde CIV em substratos clinicamente relevantes.

Fluoruro diamino de plata comparado con técnica de restauración atraumática para el tratamiento de caries cavitadas en dentición primaria y mixta primera fase / Silver diamine fluoride compared to atraumatic restorative technique for the treatment of caries in primary and mixed first phase dentition

INTRODUCCIÓN: Las lesiones de caries cavitadas en dentición primaria y mixta requieren un tratamiento oportuno, para evitar así la progresión de la caries. El fluoruro diamino de plata ha surgido como una alternativa a la técnica de restauración atraumática debido a su fácil aplicación. Sin embargo, aún existe incertidumbre en relación a su efectividad y seguridad. MÉTODOS: Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un metanálisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES: Identificamos diez revisiones sistemáticas que en conjunto incluyeron dos estudios primarios, ambos ensayos aleatorizados. Concluimos que el fluoruro diamino de plata en comparación a la técnica de restauración atraumática podría aumentar el arresto de caries en dentición primaria y mixta primera fase, pero la certeza de la evidencia ha sido evaluada como baja. Por otra parte, el tratamiento con fluoruro diamino de plata comparado con la técnica de restauración atraumática (ART) probablemente aumenta el riesgo de eventos adversos

INTRODUCTION: Cavitated carious lesions in primary and mixed dentition require prompt treatment to control caries progression. Silver diamine fluoride has emerged as an alternative to the atraumatic restorative technique due to its easy application. However, there is still uncertainty regarding its effectiveness and safety. METHODS: We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a metanalysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS: We identified ten systematic reviews, including two studies overall, which are randomized trials. We concluded that silver diamine fluoride compared to the atraumatic restorative technique may increase the arrest of caries in primary and mixed first phase dentition, however, the certainty of the evidence has been assessed as low. On the other hand, treatment with silver diamine fluoride compared to the atraumatic restorative technique (ART) probably increases the risk of adverse events.

System dynamics modeling for tooth decay treatment in Brazilian children

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.

Resultados: Os CDs afirmaram, nas duas etapas da pesquisa, conhecer o ART e julgaram-no útil em Saúde Pública, fazendo uso das restaurações atraumáticas (RA) rotineiramente. Houve modificações nas percepções referentes ao caráter definitivo das RA; na indicação da técnica de acordo com a característica da lesão cariosa e de acordo com a idade do paciente; na utilização do ácido poliacrílico e de agentes de proteção para o cimento de ionômero de vidro (CIV), entre outras. Além disso, os dentistas passaram a reconhecer o CIV como material essencial à técnica e a aceitar a manutenção da dentina cariada. Houve modificação no hábito da leitura científica sobre o ART entre os profissionais avaliados, além do aumento do número de indivíduos que receberam capacitações sobre ART no serviço. Conclusão: concluiu-se que houve modificações positivas no conhecimento teórico/técnico e na aceitação da técnica ART entre os profissionais entrevistados, reconhecendo assim a importância das capacitações oferecidas no serviço

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.

Does low-cost GIC have the same survival rate as high-viscosity GIC in atraumatic restorative treatments? A RCT

Abstract Atraumatic Restorative Treatment (ART) is one of the strategies used to control dental caries; it involves hand instruments for removal of carious tissue, and restorations using high-viscosity Glass Ionomer Cement (GIC). The present controlled clinical trial aimed to evaluate the performance of low-cost GIC indicated for ART in primary teeth, compared with high-viscosity GIC, after one year of follow-up. Two-to six-year-old children with dentin caries lesions on one or two surfaces of anterior and posterior teeth were selected. The children were randomly assigned to 2 groups according to the restorative material used: G1 (control) - Ketac Molar®; G2 (experimental) - Vitro Molar®. Treatments were performed in a school setting, following the guidelines of the ART. A total of 728 restorations were performed in 243 children. Descriptive analysis and Poisson regression were applied, with a significance level of p < 0.05. After 12 months, 559 (76.8%) restorations were re-evaluated. The success rate was evaluated by the prevalence ratio (PR), associated with restorations performed in primary second molars (PR = 1.21; 95%CI = 1.03-1.42), and with small (PR = 1.35; 95%CI = 1.14-1.60) or medium cavities (PR = 1.29; 95%CI = 1.08-1.55), using Ketac Molar® material (PR= 1.07; 95%CI = 1.01-1.15), considering p < 0.05. Small or medium restorations in primary second molars performed with high-viscosity GIC (Ketac Molar®) were more successful than restorations performed with low-cost GIC indicated for ART.

Objetivo: Evaluar la longevidad de restauraciones de Tratamiento Restaurador Atraumático (TRA), utilizando dos mate-riales diferentes: un Cemento de Ionómero de Vidrio (CIV) de bajo costo y una Resina Compuesta de nanopartículas (RC), en cavidades ocluso-proximales de molares temporales. Materiales y métodos: Un total de 83 dientes fueron selecciona-dos en 43 niños de siete a diez años de edad, que presentaron al menos una lesión de caries ocluso proximal, en la ciudad de Cosmópolis / SP, Brasil. Los pacientes fueron asignados en dos grupos: CIV de bajo costo (Vitromolar - Nova DFL) y resina compuesta de nanopartículas (RC) (Filtek Z350 XT - 3M ESPE). Todos los procedimientos se realizaron de acuerdo con los principios del TRA. Las restauraciones fueron evaluadas después de 3, 6, 9 y 12 meses por un examinador entrena-do. Para verificar la tasa de sobrevida de las restauraciones utilizamos el análisis de sobrevida de Kaplan-Meier y la prueba de Log-Rank; y, para evaluar la asociación entre el resultado y las variables del paciente se aplicó la prueba de regresión de Cox. El nivel de significancia para todas las pruebas fue del 5%. Resultados: Después de 12 meses de seguimiento, la sobrevida global de las restauraciones fue de 75,3%. Las tasas de sobrevida del CIV y de la RC fueron 62.2% y 93.7%, respectivamente. El análisis estadístico mostró diferencias significativas entre los materiales, donde la RC tuvo un mejor desempeño (HR = 0.15, IC 0.03 a 0.68, p = 0.014) que el CIV de bajo costo. No se encontraron diferencias estadísticas para otras variables (p >0.05). Conclusión: La utilización de resina compuesta de nanopartículas en las restauraciones de TRA tuvo un mejor rendimiento en comparación con el cemento de ionómero de vidrio de bajo costo, después de una evaluación de 12 meses. Registro de prueba: REBEC (Registro Brasileño de Ensayos Clínicos) # RBR-8sw24r.

Objective: To evaluate the longevity of ART restorations using two different materials: a low-cost Glass Ionomer Cement (GIC) and nanoparticle Composite Resin (CR) in occlusal-proximal cavities of primary molars. Material and methods: A total of 83 teeth were selected among 43 children, aged seven to ten years old, which presented at least one multi-sur-face caries lesion, in the city of Cosmópolis/SP, Brazil. Patients were allocated into two groups: low cost GIC (Vitromo-lar ­ Nova DFL) and nanoparticle composite resin (CR) (Filtek Z350 XT ­ 3M ESPE). All procedures were performed according to ART guidelines. The restorations were evaluated after 3, 6, 9 and 12 months by a trained examiner. To verify the survival rate of the restorations we used Kaplan-Meier survival analysis and log-rank test. To evaluate the association between the outcome and patient variables was applied Cox regression test. The significance level for all tests was 5%. Results: After 12 months of follow-up, overall survival of the restorations was 75.3%. The GIC and CR survival rates were 62.2%, 93.7%, respectively. Statistical analysis showed significant differences between materials, where the CR performed better (HR = 0.15, CI 0.03 to 0.68; p = 0.014) than low cost GIC. No statistical differences were found for other variables (p >0.05). Conclusion: The use of nanoparticle composite resin in ART restorations performed better when compared to low cost glass ionomer cement after 12 months evaluation.

Survival analysis of ART restorations in primary molars of preschool children: 1 year follow-up / Análise de sobrevivência de restaurações ART em molares decíduos de crianças com idade pré-escolar: acompanhamento de 1 ano

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.

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.
