Evaluation of the microhardness of enamel affected by incipient caries and treated by two types of fluoride varnishes: In vitro study
Fluoride has shown its effectiveness in the therapy of initial lesions of caries. Currently, there are new fluoride varnishes with additional remineralizing agents, to treat lesions of non-cavitated caries in a non-invasive way, promoting the remineralization of the enamel. Objective: To determine t...

| description | Fluoride has shown its effectiveness in the therapy of initial lesions of caries. Currently, there are new fluoride varnishes with additional remineralizing agents, to treat lesions of non-cavitated caries in a non-invasive way, promoting the remineralization of the enamel. Objective: To determine the microhardness of enamel with incipient caries lesions treated with two fluoride varnishes. Materials and methods: In vitro experimental study. The sample consisted of 35 enamel blocks, which were randomly divided into 3 groups. G1 (n=5): negative control; G2 (n=15): Fluorine varnish (Flúor protector - Ivoclar Vivadent) and G3 (n=15): Fluorine varnish with Tricalcium Phosphate (Clinpro White Varnish - 3M ESPE). Three indentations were made by means of a microhardness meter, in order to obtain the initial hardness, then the samples were demineralized with the purpose of producing incipient lesions, where 3 indentations were made again to obtain the microhardness of the demineralized enamel, after this phase the remineralizing solution in each sample and a cyclical pH regime was followed during 7 days to simulate the oral conditions, after this period 3 indentations were made in each sample to obtain the final hardness of the remineralized enamel, reaching a total of 9 indentations per sample. The data were analyzed using the Scheffé test and the Student’s T test with a level of significance of 5%. Results: There was a significant difference between the fluoride varnish with Tricalcium Phosphate (TCP) and the control group (p=0.03). No significant differences were found between the different fluorinated varnishes (p=0.09). A significant improvement of the microhardness after treatment of both fluoride varnishes was observed (p<0.001). Conclusion: The two types of fluoride varnishes efficiently increased the microhardness of enamel with incipient caries lesion, without significant difference between these two. |

En la actualidad, existen nuevos barnices de flúor con agentes remineralizantes adicionales, con la finalidad de tratar las lesiones de caries no cavitadas de una forma no invasiva, promoviendo la remineralización del esmalte. Objetivo: Determinar la microdureza del esmalte con lesiones de caries incipientes tratados con dos barnices fluorados. Materiales y métodos: Estudio experimental in vitro. La muestra estuvo constituida por 35 bloques de esmalte, que fueron divididos de manera aleatoria en 3 grupos. G1(n=5): control negativo; G2 (n=15): Barniz de Flúor (Flúor protector- Ivoclar Vivadent) y G3(n=15): Barniz de flúor con Fosfato Tricálcico (Clinpro White Varnish- 3M ESPE). Se realizaron 3 indentaciones mediante un microdurómetro, con el fin de obtener la dureza inicial, luego se desmineralizaron las muestras con la finalidad de producir lesiones incipientes, donde se realizaron nuevamente 3 indentaciones para obtener la microdureza del esmalte desmineralizado, concluida esta fase se colocó el remineralizante en cada muestra y se siguió un régimen de pH cíclico durante 7 días para simular las condiciones bucales, transcurrido este periodo se realizaron 3 indentaciones en cada muestra para obtener la dureza final del esmalte remineralizado, llegando a un total de 9 indentaciones por muestra. Los datos se analizaron mediante el test de Scheffé y la prueba T de Student con un nivel de significancia del 5%. Resultados: Existió diferencia significativa entre el barniz fluorado con Fosfato Tricálcico (TCP) con el grupo control (p=0,03). No se encontraron diferencias significativas entre los diferentes barnices fluorados (p=0,09). Fue observada una mejora significativa de la microdureza postratamiento de ambos barnices de flúor (p<0.001). Conclusión: Los dos tipos de barnices de flúor incrementaron de manera eficiente la microdureza del esmalte con lesión de caries incipiente, sin existir diferencia significativa entre estos dos.Universidad Central del Ecuador2018-10-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistadigital.uce.edu.ec/index.php/odontologia/article/view/107410.29166/odontología.vol19.n2.40-52Odontología; Vol. 19 Núm. 2 (2017): Julio-Diciembre; 40-521390-996710.29166/odontologia/19/2/2017reponame:Revista Odontologíainstname:Universidad Central del Ecuadorinstacron:UCEspahttps://revistadigital.uce.edu.ec/index.php/odontologia/article/view/1074/1076info:eu-repo/semantics/openAccess2020-08-15T15:32:47Zoai:revistadigital.uce.edu.ec:article/1074Portal de revistashttps://revistadigital.uce.edu.ec/Universidad públicahttps://uce.edu.ec/**Ecuador*1390-99671390-7468opendoar:02020-08-15T15:32:47Revista Odontología - Universidad Central del Ecuadorfalse |
