Clinical assessment of glass ionomer/composite resin sealant restorations in permanent teeth: results of a field trial after 1 year

Abstract

Summary. A large field trial is in progress in the Community Dental Service in the West of Scotland to evaluate the effectiveness of glass ionomer/composite resin sealant restorations in the treatment of fissure caries. 128 of the restorations were placed by 14 community dental officers. After 1 year, 98 restorations were reviewed. All of the glass ionomer restorations were retained but only 12 of the sealants were completely intact. Sealant was retained over only 32% of the restorations and in 13%, 48% and 69% of adjacent buccal, occlusal and palatal fissures, respectively. Résumé. Une ětude extensive est en cours de réalisation dans les services dentaires communautaires de l'Ouest de l'Ecosse et porte sur l'évaluation des obturations par ciment verre ionomère et composite pour scellement dans le traitement des caries des fissures. Cent vingt huit obturations ont été posées par 14 practiciens. Après un an, 98 obturations ont été examinées. Toutes les obturations au verre ionomère étaient en place mais seulement 12 composites de scellement étaient intacts. Les composites de scellement étaient en place seulement dans 32% des obturations et dans 13%, 48% et 69% des fissures buccales, occlusales et palatines respectivement. Zusammenfassung. In West‐Shotland ist eine Feldstudie im Gange welche den Erfolg einer kombinierten Glasionomer‐Füllung mit einer Fissuren‐Versiegelung zur Behandlung von Fissurenkaries beurteilt. 128 Restorationen wurden von 14 Gemeindezahnärzte gelegt. Nach einem Jahr wurden 98 Restorationen beurteilt. Alle Glasionomer Füllungen waren intakt aber nur 12 der Versiegelungen. Versiegler wurde noch gefunden über 32% der Restorationen und in 13% der bukkalen in 48% der okklusalen und in 69% der palatinalen Fissuren. Resumen. Un estudio de campo esta en progreso en el Servicio de Odontalgía Comunitaria en el Oeste de Escocia para evaluar la efectividad de los ionómeros de vidrio/sellante de resina en el tratamiento de caries en las fisuras. Un total de 128 testauraciones fueron colocadas por 14 odontólogos. Al año, 98 de las restauraciones han sido evaluadas. Todas las restauraciones de ionómero de vidrio estan intactas, pero solo 12 de los sellantes estan completamente intactos. El sellante se retuvo sobre las restauraciones solo en 32% de los casos y en 13%, 48% y 69% de las fisuras vestibulares, oclusales y pàlatinas respectivamente.

Assessment of the inhibitory effects of fissure sealants on the demineralization of primary teeth using an automatic pH-cycling system

“…Fissure sealant is used for prevention of caries in the pit and fissure area in individuals with a high risk of caries 4,5) . In previous studies, fissure sealant was shown to be effective for prevention of caries in the pit and fissure area 6,7) , and this technology is now being developed 8,9) . However, the effects of fissure sealant on the surrounding enamel are unknown.…”

Avaliação de dois cimentos de ionômero de vidro comparados a um selante resinoso, utilizados para selamento de fossas e fisuras aplicados em esmalte bovino hígido, sob condições de severo desafio cariogênico: estudo in situ

“…A aplicação de selantes resinosos tem se mostrado efetiva 51,119,125 , porém, esta técnica é muito sensível e pode ser influenciada por vários fatores: colaboração do paciente; habilidade do profissional; além da contaminação do campo operatório 67 . Esse último aspecto dificulta sua aplicação em crianças e dentes jovens, dependendo do estágio de erupção dentária, onde nem sempre a utilização de isolamento absoluto é possível.…”
