Six-month evaluation of ART one-surface restorations in a community with high caries experience in Brazil

Abstract

The aim of this study to evaluate the success rate in one-surface ART restorations placed in permanent molars using a glass ionomer cement especially developed for ART in a community with high caries experience; to evaluate the operator influence on its success, post-operative sensitivity and technique acceptance by patients. Prior to placement of the restorations, the Gingival Bleeding Index, Visible Plaque Index, DMFT, dmft indices and treatment needed were assessed. One hundred and fifty five one-surface restorations were placed in permanent molars of school children, according to the WHO ART manual, 1997. After 6 months, the success rate was verified clinically and by slides. At baseline, the mean DMFT was 2.56 (±1.08) and the mean dmft, 2.53 (±2.33). Operators A and B have placed 102 and 53 ART restorations respectively. The mean time of placement was 16 minutes and 25 seconds to operator A and 14 minutes and 43 seconds to operator B. At 6-month follow up, 152 ART restorations were evaluated and 97.3% were assessed to be successful. Two restorations were excluded from the sample because the ART restorations were replaced by amalgam fillings. Only 4 restorations have failed, in which 2 due to caries, 1 due to fistula presence and the other because the restoration was lost. Four patients reported postoperative sensitivity. At this study period, ART treatment seems to be suitable for its purpose. Further evaluations are necessary to the new glass ionomer cements especially developed for ART technique provided good results at 6-month follow up in a community with high DMFT and dmft indices. The success rate for one-surface cavities in permanent molars was 97.3%, and the studied indices seemed to have no influence in this early evolution period.

Comparasion of two minimally invasive methods on the longevity of glass ionomer cement restorations: short-term results of a pilot study

“…Since its introduction, the ART approach has been subjected to research. A large number of these studies have investigated the survival of GIC restorations 4 · 5 · 10 · 13 · 18 · 25 . Nevertheless, little is known about the performance of restorations placed on caries-affected dentin excavated with the CM permanent teeth 11 .…”

Permanencia de Restauraciones Oclusales Realizadas con Técnica Restaurativa Atraumática (TRA) en Dientes Permanentes

“…Estos trabajos evaluaron la permanencia de las restauraciones después de 8 y 6 meses correspondientemente. Por otro lado, los resultados difieren de estudios donde se obtuvieron porcentajes de permanencia superior en un tiempo similar (Dülgergil et al, 2005;Bresciani et al, 2005), encontrándose una supervivencia de 92,4% y de 97,3% respectivamente tras seis meses de tratamiento con vidrio ionómero convencional. Estos resultados podrían diferir de los obtenidos en el presente estudio por distintos factores, como el tamaño de la cavidad o mantención de los hábitos de higiene de los pacientes.…”

Emprego do Cimento de Ionômero de Vidro: Uma Revisão Sistemática

“…A Tabela 4 mostra o número de arti gos que estudaram falhas em restaurações de CIV. [23][24][25] . No meio ambiente oral fatores como manipulação do material restaurador, estresses fí sicos, hábitos masti gatórios, componentes da dieta e mudanças na temperatura e pH, atuando simultaneamente, podem acelerar a degradação da interface biomaterial-dente, contribuindo assim para o surgimento de falhas na restauração 19 .…”
