• Os autores declaram que não há conflito de interesse. ResumoObjetivo: conhecer o tipo de informação encontrada na internet sobre a transmissão de cárie dentária em crianças. Material e Métodos: a coleta de dados foi realizada através de uma busca eletrônica utilizando-se os termos "cárie pega" e "transmissão de cárie" na ferramenta de busca do Google®. Um pesquisador recuperou, leu e realizou a extração dos dados dos 30 primeiros registros de resultados de cada busca, utilizando uma tabela no Excel TM . Esses dados foram analisados por três pesquisadores, a partir de critérios pré-definidos, quanto à presença de informações que contribuíssem para responder a dúvidas sobre a transmissão da cárie em crianças. Resultados: dos 60 registros, nove foram encontrados em duplicata, sendo analisados uma única vez. Foram excluídos os resultados de sítios indisponíveis (n = 1) e os relacionados a artigos científicos (n = 4), imagens (n = 1), vídeos (n = 1) e sítios de perguntas e respostas (n = 1). Portanto, 43 registros foram recuperados, lidos e analisados. Vinte e cinco sítios (58,1%) afirmavam que cárie é uma doença transmissível. Desses, 20% (n = 5) afirmavam que a doença podia ser transmitida da mãe para a criança e 20% (n = 5) afirmavam que outros adultos também poderiam transmitir a cárie para a criança. Dentre os mecanismos de transmissão, o mais citado foi o beijo (n = 19). Nenhum dos sítios mencionou que a cárie poderia ser classificada como uma disbiose. Conclusão: esses estudos reforçam a necessidade de construção de canais digitais de popularização da ciência que divulguem informações relevantes para a promoção da saúde bucal de crianças com base nas evidências científicas atuais.

AbstrAct Objective: this cross-sectional observational study aimed to assess the type of information found on the Internet about the transmission of dental caries in children. Material and Methods: data was collected through an electronic search by entering the keywords "cáriepega" and "transmissão de cárie" in the Google® Transmission of this disease mostly occurs through a kiss (n = 19). Although caries is considered as a dysbiosis, this information does not seem to reach the population.

"Is caries transmissible?" Information on caries transmission in children, found via Google ® Search Engine IntroduçãoA internet é uma importante ferramenta em que pessoas de diferentes idades recorrem em busca das mais variadas informações. Estima-se que em 2016 quase 3 bilhões de pessoas, cerca de 40,4% da população mundial, tenham acesso à internet.1 Atualmente, a internet é utilizada por mais de 100 milhões de brasileiros, cerca de 66% da população.2 Apesar de uma parcela significativa da população brasileira ainda possuir ...

BackgroundFluoride varnish (FV) is a convenient way of professionally applying fluoride in preschoolers. However, its modest anticaries effect highlights the need for economic evaluations.AimTo assess economic evaluations reporting applications of FV to reduce caries incidence in preschoolers.DesignWe included full economic evaluations with preschool participants, in which the intervention was FV and the outcome was related to dentin caries. We searched in CENTRAL; MEDLINE via PubMed; WEB OF SCIENCE; EMBASE; SCOPUS; LILACS; BBO; and BVS Economia em saúde, OpenGrey, and EconoLit. Clinical trial registers, thesis and dissertations, and meeting abstracts were hand searched, as well as 11 dental journals. Risk of bias in the included studies was assessed using the Philips' and Drummond's (full and simplified) tools.ResultsTitles and abstracts of 2871 articles were evaluated, and 200 were read in full. Eight cost‐effectiveness studies were included: five modeling and three within‐trial evaluations. None of the studies gave sufficient information to allow a thorough assessment using the bias tools. We did not combine the results of the studies due to the great heterogeneity among them. Four studies reported that FV in preschool children was a cost‐effective measure, but in one of these studies, sealants and fluoride toothpaste were more cost‐effective measures than the varnish, and three studies used limited data that compromised the generalizability of their results. The other four studies showed a large increase in costs due to the application of varnish and/or low cost‐effectiveness.ConclusionWe did not find convincing overall evidence that applying FV in preschoolers is an anticaries cost‐effective measure. The protocol of this systematic review is available at Open Science Framework (https://osf.io/xw5va/).

Objectives The aims of this retrospective study were to investigate the types of traumatic dental injury recorded in an oral health service within a ten-year period and to report the type of surface against which the traumatic dental injury occurred. Methods Dental records from children assisted in the Dental Trauma Clinic at the Rio de Janeiro State University’s School of Dentistry, between 2006 and 2016, were analyzed. Only those records who had registered some type of trauma in the primary anterior teeth (incisors and canines) and aged 0-96 months at the time of trauma were considered eligible for the study. Results Four hundred and eighty-three dental records were included, totalizing 786 traumatized teeth. The average age when traumatic dental injury occurred was 37.25 months (±18.62). Enamel fractures (32.8%) and intrusive luxations (45.6%) were the most prevalent types of trauma. The majority of traumas occurred against ceramic surfaces (34%). The greatest number of teeth with lateral luxation were the ones that hit against a ceramic surface (p=0.014; U Mann-Whitney test). According to this study, the most prevalent type of trauma in the dental tissue and pulp was enamel fracture and in the periodontal tissue was intrusive luxation. The majority of traumas occurred due to falls, at home and against ceramic surfaces. Conclusion The results showed that a high frequency of the lateral luxation was associated to a traumatic impact against ceramic surfaces.
