Clinical Investigation of Two Glass–Ionomer Restoratives Used with the Atraumatic Restorative Treatment Approach in China: Two–Years Results

Abstract

Objective: To compare the clinical performance of two glass–ionomer cements, ChemFlex (Dentsply DeTrey) and Fuji IX GP (GC), when used with the atraumatic restorative treatment (ART) approach in China. Methods: Eighty–nine school children aged between 6 and 14 years who had bilateral matched pairs of carious posterior teeth were included. A split–mouth design was used in which the two materials were randomly placed on contralateral sides. The performance of the restorations was assessed directly and also indirectly from die–stone replicas at baseline and after 6, 12, and 24 months. Results: The 24–month cumulative survival rates of ART restorations in the primary teeth were 93 and 90% for the ChemFlex and Fuji IX GP class I restorations, respectively, while 40 and 46% of class II restorations placed with the respective materials were satisfactory. In the permanent dentition, only class I restorations were involved and the cumulative survival rates were 95 and 96% for ChemFlex and Fuji IX GP. For the primary teeth after 24 months, net mean occlusal wear was 87 µm for ChemFlex and 85 µm for Fuji IX GP. The occlusal wear in the permanent teeth was 75 µm for ChemFlex and 79 µm for Fuji IX GP. Conclusion: The clinical performance of both materials over a 24–month period was similar and the survival rates of class I ART restorations in both primary and permanent teeth were high.

Survival of Teeth Restored with Atraumatic Restorative Treatment in a Pediatric Rural Population

“…Our results differ when assessing the association of ART success and multi-surface restorations: we did not find significant difference in survival rates of primary teeth receiving a single versus multi-surface ART restorations [23][24][25]. We believe this is explained by the fact that our study population received replenishment of the ART restoration as needed at their follow up appointments, therefore teeth were resealed and recharged, resulting in release of fluoride into adjacent tooth structure, factors known to increase the success rate of ART restorations [10].…”

Topografia de Restaurações Realizadas Através do Tratamento Restaurador Atraumático (ART): Estudo Piloto in vivo

“…As restaurações foram analisadas segundo um critério de avaliação que definia como limite de sucesso o desgaste marginal de 0,5mm. No entanto, os artigos não mencionam a padronização de um ponto de referência para comparação dos modelos 14,15 . Assim, o método proposto pode ser válido quando os passos descritos anteriormente forem seguidos na obtenção das réplicas.…”

“…A maioria dos estudos que avaliaram restaurações atraumáticas demonstrou taxas de sucesso na dentição decídua 2,15,17,19 menores que as encontradas para a dentição permanente 2,5,9,14,20 . Outro ponto a ser considerado na avaliação de restaurações baseadas na técnica atraumática refere-se ao tipo de material utilizado.…”

“…Após a confecção das restaurações e em consultas de revisão seguintes, foram realizadas moldagens para obtenção de réplicas em resina epoxídica, as quais foram fotografadas com o uso de uma câmera digital (Pixera ® ) acoplada a um microscópio esteroscópio. As imagens obtidas foram então usadas para o cálculo da área da restauração, em diferentes intervalos de tempo, com o auxílio do Programa AutoCad® (versão 14). As diferenças proporcionais encontradas entre os valores obtidos permitiram o cálculo da integridade marginal ao longo do estudo.…”
