RESUMO

Evaluate the cytocompatibility of Calen®/ZO, Calcicur®, Vitapex®, Endoflas®, and zinc oxide/eugenol-based (ZOE) root canal pastes (RCP) to human primary osteoblasts (HPO) through a simplified model for primary teeth. The model employed pipette tips filled with 0.037 g of paste, exposed to 185 µL of culture medium for 24 h (n = 6). Release of components was analysed by Proton Nuclear Magnetic Resonance Spectroscopy (1H-NMR). HPO were exposed to conditioned media for 24 h. Cell viability was assessed by cell density and metabolic activity, and release of interleukin 6 (IL-6), vascular endothelial growth factor (VEGF) and fibroblast growth factor (bFGF) by immunological assay. Physicochemical properties and antimicrobial efficacy were also evaluated. 1H-NMR spectra analysis showed similarity between ZOE, Endoflas®, Calcicur®, and Vitapex® compared to Calen®/ZO and positive control, which showed distinct released components. Calen®/ZO and Calcicur® exhibited high alkaline pH in all periods and showed similar solubility. Calen®/ZO, ZOE, and Vitapex® showed similar flow rate. Calen®/ZO, Calcicur®, and Vitapex® did not exhibit antimicrobial efficacy. Calen®/ZO presented cytotoxicity (p < 0.05). Pastes did not increase IL-6 release compared to control. Apart from Vitapex®, all pastes significantly induced VEGF/bFGF release. Interactive effects among released products may affect biological response to filling pastes. Calcicur®, ZOE, Endoflas® and Calen®/ZO presented good to moderate cytocompatibility, with low impact on pro-inflammatory cytokine release and induction of growth factors of interest to tissue repair. This simplified model, specific for the evaluation of the cytocompatibility of RCPs on primary teeth, suggests how these pastes might contribute to bone repair in clinical situations of apical periodontitis in children.

RESUMO

Abstract Objective: To verify the concordance in the evaluation of the apical limit of obturation (ALO) in filled root canals of primary teeth between digital and visual methods. Material and Methods: Twenty periapical radiographs of endodontically treated primary teeth were digitalized and evaluated by an endodontics specialist (E1), a PhD pediatric dentist (E2), and a MSc general dentist (E3). Calibrated evaluators (Kappa = 1.00) analysed the images in a light-isolated environment two times (D1 and D2) with a one-week interval between evaluations. ALO scores were categorized as overfilled, flush-filled and underfilled. Results: The intra-rater reliability between methods was 0.82 (D1) and 0.75 (D2) for E1, 0.93 (D1 and D2) for E2, and 0.94 (D1 and D2) for E3. Inter-rater reliability ranged from 0.71 (E1 × E3) and 1.00 (E1 × E2) for the visual method to 0.76 (E1 × E3) and 0.88 (E1 × E2) for the digital method. Spearman correlation coefficients showed a similar ranking among the evaluators. There was greater disagreement among the underfilled and ideal scores. For all evaluators, the digital method favoured the identification of the ideal score. Conclusion: Both methods are suitable for the determination of the ALO of filled primary teeth and can be used in clinical practice.

RESUMO

Introduction: There is no consensus on the literature about the best root canal filling material for primary teeth. Objective: The aim of this study was to describe the root canal filling materials most widely used in clinical pediatric dentistry, showing the observed success rates. Sources of data: A search, limited to the last 10 years and, no language restriction, was performed in October 2018 in the PubMed, Cochrane and LILACS databases using the terms "pulpectomy" and "primary teeth". This narrative literature review included clinical and randomized controlled trials conducted on children who had undergone pulpectomy as root canal therapy, with at least six months of clinical and radiographic follow-up. Synthesis of data: A total of 254 papers were retrieved from the databases. After applying the inclusion and exclusion criteria, 25 papers were included in this review. Zinc oxide and eugenol (ZOE) based paste was still the most widely used root canal filling material for primary teeth in pediatric clinical research, showing an overall clinical and radiographic success ranging from 63.3% to 93.3%. Conclusion: ZOE based paste is still the most used material for root canal filling in primary teeth, although there is a trend in the use of iodoform with calcium hydroxide pastes, which show high frequencies of success.


Introdução: Não há consenso na literatura quanto ao material obturador ideal para canais radiculares de dentes decíduos. Objetivo : O objetivo deste estudo foi descrever os materiais obturadores para canais radiculares mais utilizados na clínica Odontopediátrica, mostrando os índices de sucesso observados. Fonte dos dados : Uma busca, limitada aos últimos 10 anos e sem restrição de idioma, foi realizada em outubro de 2018 nas bases de dados PubMed, Cochrane e LILACS usando os termos "pulpectomy" e "primary teeth". Esta revisão narrativa da literatura incluiu estudos clínicos controlados randomizados em crianças submetidas a pulpectomia como tratamento endodôntico, com, no mínimo, seis meses de acompanhamento clínico e radiográfico. Síntese dos dados : Foram recuperados nas bases de dados 254 artigos. Após a aplicação dos critérios de inclusão e exclusão um total de 25 artigos foram incluídos nesta revisão. A pasta à base de óxido de zinco e eugenol (OZE) foi o material obturador mais utilizado para canais radiculares de dentes decíduos em pesquisa clínica Odontopediátrica, mostrando sucesso clínico e radiográfico geral que variou de 63,3% a 93,3%. Conclusão : A pasta à base de óxido de zinco e eugenol é o material mais utilizado para a obturação de canais radiculares de dentes decíduos, embora exista uma tendência para a utilização de pastas à base de iodofórmio com hidróxido de cálcio, que apresentam altas frequências de sucesso.

RESUMO

Introduction: Adolescents present a potential risk for the development of caries and periodontal diseases. Objective: The objective of the present study was to review the indicators of self-care and oral health in brazilian adolescents. Methodology: The search strategy (adolescent AND oral health) AND Brazil* was used in Pubmed and LILACS databases. Articles published between 2012 and 2017 that presented data on self-care and oral health of brazilian adolescents were included in this review. Synthesis of data: 837 and 1375 articles were retrieved from the Pubmed and LILACS databases, respectively. After applying the inclusion and exclusion criteria, 7 articles were included. The characteristics of the studies and the data obtained regarding sel-care and oral health of the adolescents were presented descriptively. Most of the studies included adolescents between the ages of 15 and 19 years, the majority of whom sought dental care in less than one year of the interview and caries was the most prevalent disease compared to gingival bleeding. Conclusion: According to the indicators of self-care evaluated, the majority of Brazilian adolescents reported having sought dental care in less than one year and caries disease was the most prevalent condition.


Introdução: Adolescentes apresentam potencial risco para o desenvolvimento das doenças cárie e periodontal. Objetivo: O objetivo do presente estudo foi revisar, na literatura, dados acerca da saúde oral de adolescentes brasileiros através da prevalência ou presença de cárie e sangramento gengival, como indicadores indiretos (consequências), e frequências de escovação dentária, uso de fio dental e visita odontológica como indicadores diretos deautocuidado oral. Fontes dos dados: Utilizou-se a estratégia de busca ((adolescent AND oralhealth) AND Brazil*) nas bases de dados PubMed e LILACS. Os artigos publicados entre setembro 2012-2017 que apresentaram dados de ao menos um dos indicadores de saúde oral e autocuidado em adolescentes brasileiros, foram incluídos nesta revisão. As características dos estudos e os dados obtidos foram apresentados de forma descritiva. Síntese dos dados: Foram recuperados nas bases de dados PubMed e LILACS 837 e 1375 artigos, respectivamente. Após a aplicação dos critérios de inclusão e exclusão, 10 artigos foram incluídos. A maioria dos estudos incluiu adolescentes entre 15 e 19 anos, com relato de atendimento odontológico realizado em menos de 1 ano antes da entrevista, sendo a cárie a alteração bucal mais prevalente. Conclusão: Dentro das limitações do presente estudo, de acordo com os dados obtidos através dos indicadores de autocuidado pesquisados, os adolescentes brasileiros mostraram cárie como o agravo observado mais prevalente; as frequências de escovação e uso de fio dental variaram na região Sul; e relataram atendimento odontológico no período inferior a um ano da entrevista.
