“…Primary teeth show morphological as well as histopathological characteristics, and the paradigms on adhesive techniques on permanent teeth cannot simply be transferred to the primary dentition. In terms of primary enamel, the presented research results confirm the convincing adhesive strength of adhesive systems based on phosphoric etching, as known from publications on the primary as well as the permanent dentition [26,27]. However, no significant difference of shear bond strength was determined comparing the experimental groups, except for Prime&Bond NT without phosphoric etching.…”

“…The results showed greater adherence of the OptiBond FL at 24h, compared to Fluroshield, Clinpro TM XT and Vitremer TM , which showed a similar adhesion. This result is consistent with other studies 11,15,33,34 and can be explained by the lower viscosity of the adhesive system, as compared to other materials. OptiBond FL fulfills adequately the micro porosities of enamel produced by acid conditioning 15 , forming extensions of the material (tags) 37 that favored the adhesion.…”

OptiBond FL fulfills adequately the micro porosities of enamel produced by acid conditioning 15 , forming extensions of the material (tags) 37 that favored the adhesion. On the other hand, the highest viscosity of other materials may have resulted in less wetting of surfaces of the conditioned enamel, limiting the formation of extensions to the interior of the enamel, which can justify the lowest values of adherence among them in 24 hours.…”

“…The dental crowns were then subjected to prophylaxis with suspension of pumice and water with brush of Robinson at low rotation speed, and sealants were applied on the occlusal surface of the teeth, in accordance with the indication by each manufacturer, as described in Table 1. After the application of sealants and photo activation, rectangular blocks of composite resin Filtek Z250 were built incrementally (3 x 2 mm) on the occlusal surface 15,33,34 . The specimens were stored in ultrapure water for 24 hours at 37 o C, and after this period cuts were made with diamond disc (Extec 12205 High Concentration; Enfield, CT, USA) in the mesiodistal direction, in cutting machine of high precision (Isomet buehler Ltd, 1000; Lake Bluff, IL, USA).…”

The study aims to evaluate the bond strength of sealants on deciduous molars. Clinpro ™ XT, Vitremer ™, Fluroshield and Optibond FL materials were applied to the occlusal surface of 40 deciduous lower molars (n = 5). The teeth were prepared for the micro tensile test, obtaining a specimen in a stick format with a cross-sectional area of 0.8 mm 2 . After 24 hours and 6 months of restorative procedures, the specimens were traversed in universal test machine. The statistical analysis used the tooth as experimental unit, considering the adhesive and mixed fractures data, through Variance Analysis of repeated measures and Tukey tests (α = 0.05). There was a difference among the adhesion of the materials in 24 h, with higher union strength for Optibond FL (31.20 ± 1.36 MPa), significantly higher than that of Clinpro ™ XT (20.23 ± 1.16 MPa), Fluroshield (24.61 ± 2.76 MPa) and Vitremer™ (21.31 ± 2.32 MPa), which were similar. After 6 months of storage, the Clinpro ™ XT bond strength remained (22.18 ± 2.91 MPa), Optibond FL decreased (20.77 ± 1.53 MPa), but remained similar to that of Clinpro ™ XT in 6 months. The lowest adhesion values at 6 months were of Fluroshield (11.14 ± 1.98 Mpa) and Vitremer (5.29 ± 0.58 Mpa). It was concluded that the bond strength of the sealants to the occlusal surface of the deciduous molars was influenced by the material, with Clinpro ™ XT being the only material that maintained the bond strength values after 6 months. ResumoO presente estudo teve como objetivo avaliar a adesão de selantes em molares decíduos. Os materiais Clinpro™ XT, Vitremer TM , Fluroshield e Optibond FL foram aplicados na superfície oclusal de 40 molares inferiores decíduos (n=5). Os dentes foram preparados para o ensaio de microtração, com obtenção de corpo-de-prova em formato de palito com área de seção transversal de 0,8 mm 2 . Após 24 horas e 6 meses da realização dos procedimentos restauradores, os espécimes foram tracionados em máquina de ensaio universal. A análise estatística usou como unidade experimental o dente, considerando os dados de fraturas adesivas e mistas, pelos testes de Análise de Variância de medidas repetidas e Tukey (α=0,05). Houve diferença entre a adesão dos materiais em 24 h, com maior resistência de se que a resistência de união dos selantes à superfície oclusal dos molares decíduos foi influenciada pelo material, sendo o Clinpro™ XT o único material que manteve os valores de resistência de união após 6 meses.Palavras-chave: Selantes de Fossas e Fissuras.

“…Of the etch-and-rinse adhesive systems used in the present study, Ramires-Romito et al [39] reported higher microtensile bond strength of primary enamel with OptiBond FL than with the self-etch version, OptiBond Solo SE. Lemos et al [40] demonstrated higher bond strength and a better-defined etching pattern and resin tags on primary enamel with OptiBond FL than with OptiBond All-in-One. Despite the results reported for primary enamel, it has been suggested that optimal bonding to primary dentin is achieved with self-etch adhesive systems [4].…”

The purpose of this study was to assess the clinical performance of composite restorations placed with different adhesive systems in primary teeth. In 32 patients, 128 composite restorations were placed using a split-mouth design as follows (4 groups/patient): three-step etch-and-rinse (Group 1), two-step etch-and-rinse (Group 2), two-step self-etch (Group 3), and one-step self-etch (Group 4). The restorations were clinically evaluated at baseline and at 6, 18, and 36 months according to the FDI criteria. There was no significant difference between the adhesive systems in retention of the restorations (p > 0.05). Over time, there was a statistically significant decrease in marginal adaptation in all groups, whereas surface and marginal staining significantly increased in Groups 3 and 4 (p < 0.05). The etch-and-rinse adhesive systems resulted in better marginal adaptation than the self-etch adhesive systems (p < 0.05). It was concluded that preetching of the primary enamel might help improve the clinical performance of the self-etch adhesive systems in primary teeth.
