“…A retrospective study 2 showed that the longevity of adhesive restorations placed in high caries risk children up to 36 months was 34.8%. Conversely, the survival of repaired restorations at 36 months reached 43.7%, providing evidence that repair increases the survival of failed restorations in primary teeth 2 .…”

“…In contrast, repair (i.e. removal of the defective part of the restoration, followed by restoration of the prepared defect) may increase the survival of resin composite restorations placed in both primary and permanent teeth 2,3 , prolonging the tooth retention time. Therefore, it has been considered preferable, whenever possible, to perform a repair as an alternative to restoration replacement 4 .…”

Este estudo investigou o ensino do reparo de restauração direta de resina composta em dentes decíduos nos cursos de graduação em Odontologia no Brasil. Um questionário referente a este tópico foi desenvolvido e enviado por e-mail para 205 cursos de Odontologia entre maio e setembro de 2019. Os dados obtidos foram analisados descritivamente. A taxa de resposta foi de 43,4% e dos cursos respondentes, 82% incluíram esse tópico em seu currículo. As duas razões mais comumente relatadas para o ensino do reparo de restaurações de resina composta foram preservação da estrutura dentária (95,9%) e redução do risco de complicações pulpares (71,2%). No que diz respeito ao protocolo para reparo, poucos instituições (24,7%) ensinaram o desgaste mecânico da porção da resina a ser reparada com pontas diamantadas. Por outro lado, o condicionamento com ácido fosfórico da superfície preparada foi recomendado por 87,7% das instituições e 76,7% indicaram aplicação de adesivo na superfície preparada. O material mais comumente ensinado para reparo foi resina composta convencional. O ensino do reparo de restaurações de resina composta com falhas foi estabelecido dentro do currículo dos cursos de graduação em Odontologia no Brasil. No entanto, não há consenso sobre o protocolo clínico para reparo.

“…In case the etiological factors are not controlled, the restorations would have a limited capacity to survive. That is why the I S S U E 1 , 2 0 2 1 1286 MedInform restorations in primary dentition usually do not last long and the main reason for their failure is development of secondary carious lesion [4,5,6]. Secondary caries lesion is defined as a primary lesion, developing near an existing restoration, used for a certain period of time [6,7].…”

Aim:The aim of this study is to evaluate the surface roughness values of four restorative materials, used for restorations in primary dentition. Materials and methods: Five disc-shaped specimens were prepared for each material using a cylindrical Teflon mold with dimensions 5x2 mm, covered with Mylar strips. After setting, the specimens were polished sequentially with coarse, medium and fine aluminum oxide discs. The mean surface roughness of all the samples after polishing was measured using a surface profilometer. Results: Fuji IX GP showed statistically significant higher surface roughness values. There was no statistically significant difference in roughness values between the other three materials, although the giomer Beautifil II demonstrated the lowest roughness values. Conclusions: It can be concluded that the composition (presence and absence of resin) and particle size of the restorative materials affect their surface characteristics and their degree of polish ability as the material with larger particles size and without resin content, Fuji IX GP, demonstrated significantly higher surface roughness values.

“…7 Although most dentists claim to perform repairs, and this approach has been adopted by most dental schools, the proportion of truly repaired restorations is still low. 8 Repair may increase the survival of restorations placed in primary and permanent teeth, 9,10 but there is no gold standard protocol or materials established for treating aged composite surfaces before repair. 11 Successful repair procedures require a durable bond between the old restoration and the new composite resin.…”

This in vitro study aimed to evaluate the effect of a silane-containing universal adhesive used with or without a silane agent on the repair bond strength between aged and new composites. Forty nanohybrid composite resin blocks were stored in distilled water for 14 d and thermo-cycled. Sandpaper ground, etched, and rinsed speciments were randomly assigned into four experimental groups: silane + two-step etch-and-rinse adhesive system, two-step etch-and-rinse adhesive system, silane + silane-containing universal adhesive system, and silane-containing universal adhesive system. Blocks were repaired using the same composite. After 24 h of water storage, the blocks were sectioned and bonded sticks were submitted to microtensile testing. Ten unaged, non-repaired composite blocks were used as a reference group to evaluate the cohesive strength of the composite. Two-way ANOVA and Tukey's tests were used to analyze average µTBS. One-way ANOVA and Dunnet post-hoc tests were used to compare the cohesive strength values and bond strength obtained in the repaired groups (α = 0.05). The µTBS values were higher for the silane-containing universal adhesive compared to the two-step etch-and-rinse adhesive system (p = 0.002). Silane application improved the repair bond strength (p = 0.03). The repair bond strength ranged from 39.3 to 65.8% of the cohesive strength of the reference group. Using universal silane-containing adhesive improved the repair bond strength of composite resin compared to two-step etch-and-rinse adhesive. However, it still required prior application of a silane agent for best direct composite resin repair outcomes.
