“…The high-strength conventional GICs with improving their mechanical properties can result in decreased solubility and fluoride liberation. At 48 hours and after one week, all the groups showed decreasing in their antibacterial effect but with non-statistically significant values which may be explained by The fluoride release from resinmodified glass-ionomers is high, immediately after hardening of the restoration (within 24 hours) due to initial fluoride burst effect, followed by constant slow release of fluoride for weeks (22) . This was in agreement with (23) that explained the decrease antibacterial effect of GICs to the development of a complex buffer solution containing mainly calcium and aluminum by GIC materials (5) , which able to significantly move the pH of the solution closer to a neutral pH, as lead to decrease the fluoride release level.…”

Statement of problem: failure of any restorative system is most frequently caused by caries; it would be advantageous if the restoration possessed antibacterial properties. Objective: The purpose of this study was to assess the inhibitory activity of three different glass ionomer restorative systems against streptococcus mutans using the agar diffusion test. Material and methods: The antibacterial activity of three types of glass ionomer restorations (Ketac Fil Plus;3M, Ketac Silver Aplicap; 3M, Chemfil rock; Dentsply) were evaluated against Streptococcus mutans using the agar inhibition test. Zone of inhibition on Mitis salivarius agar plates was measured after 24 hours, 48 hours and one week. Data were explored for normality using Kolmogorov-Smirnov test of normality. And one way analysis of variance (ANOVA) test was used to compare between groups. This was followed by Tukey post hoc test for multiple pairwise comparisons. Results: At 24 hours Statistically significant largest zone of inhibition was observed with Ketac fil plus with no statistically significant difference between Ketac silver and Chemfil rock whereas at 48 hours and one week no statistically significant difference among all the tested groups. Conclusions: Within the limits of this in-vitro study it can be concluded that conventional GIC had antibacterial effect against the streptococcus mutans better than silver zinc reinforced types of GICs especially within the first 24 hours. Also addition of new elements as silver or zinc for GICs affect negatively on their anti-bacterial role as it increase their strength and hardness with decreasing solubility so limited leach out of ions from restorations.

“…37 In relation to the surface chemistry, it might be pointed out that release of fluoride from giomer 13,16,27,38,39 might result in a decrease in microbial adhesion. Some studies have shown that BA of giomer is less than that of other composite resins, which is attributed to the chemical structure of giomer.…”

“…16,27 In fact, giomer has an antibacterial effect, which is related to its fluoride release capacity. 13,16,27,38,39 It has been shown that specific monomers are released from composite resin that promote the growth of cariogenic bacteria. 7 Eick et al, 40 too, showed higher or similar BA of composite resins compared with ceramics and attributed it to the presence of specific monomers or fillers in composite resins that promote BA.…”

Introduction: Adhesion of bacteria, especially Streptococcus mutans (S. mutans) , to the surface of tooth restorations is a factor in the etiology of secondary caries. Given the ever-increasing popularity of bleaching procedures, the aim of the present study was to evaluate adhesion of S. mutans and surface roughness (SR) of microhybrid composite resin and giomer subsequent to the application of 15% carbamide peroxide.

“…Houve diferenças nas atividades antibacterianas entre os materiais, devido às diferentes quantidades de flúor e da natureza do vidro fluoretado em cada material. A resina composta com partículas ionoméricas tem uma liberação cumulativa de fluoreto de aproximadamente 20% em relação aos CIV originais 10,25 . No presente estudo, esta resina composta não demonstrou capacidade inibitória contra as cepas de Staphylococcus aureus e Escherichia coli, presumivelmente pela baixa liberação de flúor de sua superfície após estar polimerizada e da ausência de monômeros residuais que pudessem também atuar como tendo atividade antimicrobiana 26 .…”

“…Sua popularidade fez com que surgissem diferentes estudos, comparando-o a outros materiais restauradores, surgindo controvérsias sobre vantagens e desvantagens de sua utilização 9 . Ultimamente foram desenvolvidos materiais híbridos adequando as tecnologias de ionômeros de vidro e resinas compostas para superar as desvantagens dos cimentos de ionômero de vidro 10 . Surgiu, assim, o Giomer, resultado de uma tecnologia recente de resina composta como um material estético restaurador direto para restauração em dentes anteriores e posteriores 11 , apresentado como a verdadeira hibridização de ionômero de vidro e resina composta.…”

Objetivo: analisar a atividade antimicrobiana de um cimento de ionômero de vidro (IV) convencional, um cimento de IV capsulado, um cimento de IV modificado por resina e uma resina composta com partículas ionoméricas contra Staphylococcus aureus e Escherichia coli. Materiais e método: estudo laboratorial microbiológico avaliou, por meio da inibição do crescimento por ágar difusão no método do poço, a ação antimicrobiana de materiais restauradores contra Staphylococcus aureus e Escherichia Coli. Utilizaram-se 6 placas de Petri com ágar Müeller Hinton cujos poços foram preenchidos com os materiais ionoméricos manipulados conforme fabricantes (cimento de IV convencional, cimento de IV encapsulado, cimento de IV modificado por resina e resina composta com partículas ionoméricas - Ketac Molar Easy®, Riva Self Cure®, Vitremer® e Beautifil II®) e com controle (cimento de óxido de zinco e eugenol OZE e solução salina em discos de papéis). Houve incubação em estufa bacteriológica por 48 horas quando se analisou a formação ou não de halos de inibição do crescimento. Resultados: constatou-se que o cimento de IV modificado por resina apresentou atividade antibacteriana contra Escherichia coli e Staphylococcus aureus, com média de halos de 13 e 13,6mm, e o cimento controle OZE apresentou halos de 16 e 16,3mm. Os demais materiais restauradores e a solução salina não apresentaram formação de halos de inibição. Conclusão: apenas o cimento de IV modificado por resina apresentou atividade antimicrobiana contra as bactérias testadas.
