Evaluation of caries risk in pre-school children using the CAMBRA protocol and CAST index / Avaliação do risco de cárie em crianças em idade pré-escolar utilizando o protocolo CAMBRA e o índice CAST

Objective: To evaluate the risk of caries and oral health condition in children, using the CAMBRA protocol of the American Academy of Pediatric Dentistry (AAPD) and the Species and Treatment Index for Caries Assessment (CAST) in preschoolers. Method: Method: It is characterized as a cross-sectional retrospective observational analytical study, with clinical examination procedures, questionnaires and oral hygiene analysis in children from 2 to 5 years old. 507 preschoolers aged 2 to 5 years were evaluated in public daycare centers in the city of São Gonçalo - Brazil. Results: The CAMBRA protocol has a moderate risk of 55.4%, while 44.6% has a high risk of caries, from 2 to 5 years. When considering the range of 2 to 3 years apart, 67.1% of children are at high risk. The CAST index showed 10.6% of lesions caused by caries, correlated between caries and the CAST index. Conclusion: It is necessary to implement preventive strategies to reduce caries in this studied group

Comparison between dmf/DMF and ICDAS in Brazilian schoolchildren: a cross-sectional study / Comparação entre ceo/CPO e ICDAS em escolares brasileiros: um estudo transversal

The objective was to compare the use of the International Caries Detection and Assessment System (ICDAS-II) and the dmft/DMFT (WHO) indexes in epidemiological surveys in schools. Two calibrated examiners analyzed 402 public school children aged 5-12 years, in the city of Mesquita, Rio de Janeiro, Brazil, using ICDAS-II and WHO criteria. The schools are located in areas covered by the Family Health Strategy. The DMF-DMF-S, dmf-t, dmf-s, the prevalence of decayed teeth, and examination time were calculated using both systems. The research subjects participated in health education and prevention activities and oral hygiene training. Data were statistically analyzed and the mean dmf-t / DMF-T was 2.35 (sd ± 2.15) and 3.18 (sd ± 2.31), respectively, using the WHO criteria. When considering the score of the three-ICDASII the average was 2.64 (sd ± 1.89) and 3.45 (sd ± 2.48). With the score-2 ICDASII, 4386 surfaces with lesions were identified, 2795 (63.7%) were not considered when we used the dmf-t / DMF-T. The average examination time was almost twice as long to ICDAS-II (3.2 ± 1.9 min) and WHO (1.8 ± 0.9 min). Conclusion: The ICDAS-II, and provide information on non-cavitated lesions of caries, shows significant experience of dental caries in schoolchildren from the city, and can generate data comparable with previous research that used the WHO criteria

Use of the web in promoting education in oral health among schoolchildren / Uso da web na promoção de educação em saúde bucal em escolares

This study aimed to evaluate the acceptance and acquisition of knowledge through web learning related to self-care for the maintenance of oral health. The study population was children from the 4th and 5th school year, from 9 to 16 years old. It was evaluated Visible Plaque Index and Gingival Bleeding Index. Participants’ knowledge was tested at baseline and then evaluated after each web distance education moment. This education process had four web distance moments. The evaluation of knowledge was done through a questionnaire containing 10 closed questions. The time interval was 30 days between the 1st and 2nd meetings and 60 days between the subsequent meeting. Concerning the questionnaires, the different moments were compared by chi-square (X2). Only question number six presented a statistical significance at 5%, however, between the first and the second moment 100% of the questions had a significant increase of correct answers (p> 5%). It is concluded that oral health education by web, was able to improve oral hygiene and knowledge related to oral health.

Physical evaluation of the luting systems for veneer ceramic after aging / Avaliação física dos sistemas de cimentação para faceta cerâmica após envelhecimento

The aim of this in vitro study was evaluated the amount of color change and degree of conversion of the luting systems for ceramic veneer cementation. Forty-eight human incisors were randomly divided into six groups (n=8) according to the bonding procedure: RelyX Veneer/Single Bond 2; RelyX ARC/Single Bond 2; Filtek Z350 XT Flowable /Single Bond 2; Variolink Veneer/Tetric N-Bond; Variolink II/Tetric N-Bond; Tetric N-Flow/Tetric N-Bond. Ceramic veneers (IPS Empress Esthetic) were cemented using the different bonding procedures. Color differences of the ceramic surface after cementation and 300 h(150kJ/m2) of UV aging test, were examined with a colorimeter. Fourier transform infrared spectroscopy (FT-IR) was used to evaluate the degree of conversion for each luting system. Data were analyzed with one-way ANOVA and Tukey's test (α=0.05). All the luting systems demonstrated significant changes in color stability. The ΔE of the systems ranged from 6,11 to 9,33. Tetric N-Flow and RelyX Veneer showed the highest degree of conversion, while lowest values were found for RelyX ARC. All luting systems demonstrated clinically unacceptable (ΔE≥ 3.3) color changes. Despite to the dual cure of the RelyX ARC luting cement, it showed the lowest degree of conversion values, while Tetric N-Flow and RelyX Veneer presented the highest and similar degree of conversion

Avaliação dos fatores determinantes à perda dentária em usuários de um posto de saúde em Teresina, Piauí / Evaluation of the determinants of tooth loss in users of a health center in Teresina, Piauí

Introdução: A perda dentária é considerada um problema de saúde pública que gera impactos negativos na qualidade de vida do indivíduo. Objetivo: Avaliar os fatores determinantes da perda dentária em usuários de um posto de saúde em Teresina - Piauí. Método: Foram entrevistados 384 usuários, de ambos os gêneros, com faixa etária de 15 a 60 anos de idade, através de um questionário.

Avaliação da condição de saúde oral de pacientes com transtornos psiquiátricos / Patients of oral health condition evaluation with phychiatric disorders

Introdução: A perda dentária é um dos problemas de saúde bucal mais prevalentes população mundial, que acomete principalmente adultos e idosos. Objetivo: Determinar o estado de saúde oral e investigar a associação da condição de saúde bucal com variáveis sóciodemográficas de indivíduos com transtornos psiquiátricos. Método: Os pacientes eram assistidos em Centros de Atenção Psicossocial (GE) e assinaram um termo de Consentimento Livre e Esclarecido. A amostra do estudo foi de 78 pacientes psiquiátricos de idades entre 20 e 50 anos. Experiência com cárie, condições de higiene oral e periodontal foram avaliadas pelos índices CPOD, IPV (Índice de placa visível), ISG (sangramento gengival), respectivamente. Aplicou-se os testes qui-quadrado de Pearson, teste de Mann-Whitney e regressão logística na análise estatística. Como grupo controle (GC), foram recrutados pacientes que procuravam tratamento odontológico numa Unidade Básica de Saúde de Teresina-PI, os quais foram pareados segundo gênero e renda. Resultados: GC apresentou menos dentes hígidos (p=0,002). A diferença entre os grupos com relação ao CPOD foi significativa (p=0,004), especialmente no componente perdidos (p=0,004). A condição periodontal não foi significativa entre os grupos. Conclusão: Os pacientes psiquiátricos avaliados tem uma condição de saúde oral mais comprometida (número maior de dentes perdidos)

Growing knowledge: an overview of Seed Plant diversity in Brazil

Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora
