“…The bond between a high-performance adhesive fissure sealant and the tooth surface is stronger and more durable than that of a low-performance adhesive fissure sealant because the former resists contraction and functional stresses 8,9) . Consequences of using a low-performance adhesive fissure sealant are imperfect sealing, faulty and defective marginal integrity, and diminished ability to prevent marginal microleakageall of which permit a caries process to progress beneath the fissure sealant [8][9][10] . Currently, the most commonly used fissure sealants are R-based and GI-based fissure sealants.…”

The aim of this study was to compare the shear bond strengths (SBS), failure modes (adhesive, cohesive, or mixed), and marginal microleakage occurrence of conventional resin (CR)-based, glass ionomer (GI)-based, and self-adhesive resin (SAR)-based fissure sealants with or without prior phosphoric acid (PA) etching. Fifty extracted premolars were randomly and equally assigned into five groups -G1:PA+CR, G2:PA+GI, G3:GI, G4:PA+SAR, and G5:SAR. Prior PA etching significantly (p<0.05) increased the SBSs of sealants. Adhesive failure mainly occurred in teeth treated with SAR-or GI-based fissure sealants, and cohesive failure mainly occurred in PA-etched teeth. Microleakage occurrence differed significantly (p<0.05) among the five groups of treated teeth. We concluded that conditioning of a tooth's enamel surface is crucial to creating strong bonds and leak-free sealing between tooth and fissure sealant.

ÖZAmaç: Bu in vitro çalıĢmanın amacı dört farklı pürüz-lendirme yönteminin ortodontik braketlerin makaslama bağlanma dayanımı üzerine etkisini incelemektir. Metod: Bu çalıĢmada 40 yeni çekilmiĢ üst 1. premolar insan diĢi kullanıldı ve mine yüzey tedavi tipine bağlı olarak rastgele dört gruba ayrıldı (n=10): I, asitle pürüzlendirme; II, Er:YAG lazer; III, Er:YAG lazer + asit pürüzlendirme; IV, alüminyum oksit ile kumlama. DiĢler dikey bir pozisyonda kendi kendine sertleĢen akrilik içerine gömüldü ve böylece kronları açığa çıktı Paslanmaz çelik premolar braketleri standart bir iĢ-lemle tüm diĢlere yapıĢtırıldı ve tüm diĢler SBS testine tabii tutuldu. Sonra, her bir örnek için artık adeziv indeksi (adhesive remnant index -ARI) değerlendirildi. Kırılma modları miktar olarak bir stereomikroskopla ve morfolojik olarak da bir tarama elektron mikroskopu (scanning electron microscope-SEM) altında değerlen-dirildi. Ġstatistiksel analiz anlamlılık seviyesi 0.05'de kararlaĢtırılarak tek yönlü varyans analizi ve Tukey çoklu karĢılaĢtırma testi ile yapıldı. Bulgular: Her bir grup için ortalama makaslama test değerleri sırasıyla Ģöyledir: I, 10.21 ± 0.8; II, 9.33 ± 1.2; III, 13.46 ± 0.7; IV, 3.36 ± 0.6. III. grup (ErYAG lazer + asit pürüzlendirme) en yüksek SBS değerlerini gösterirken, IV. grup (kumlama) en düĢük SBS değer-lerini gösterdi ve kumlama ve diğer gruplar arasında istatistiksel olarak anlamlı bir farklılık gözlendi. ARI skorlarının değerlendirilmesi III.grupta mine yüzeyinde daha fazla adezivin kaldığını gösterdi. Sonuç: Mevcut bulgular yüzey pürüzlendirme için uygun parametrelerle Er:YAG lazerden faydalanmanın mümkün olduğudur. Anahtar Kelimeler: Makaslama bağlanma dayanımı, kumlama, Er-YAG lazer, asitle pürüzlendirme, ortodontik bağlanma. ABSTRACT Aim:The purpose of this in vitro study is to evaluate the effect of four different conditioning methods on the shear bond strength (SBS) of orthodontic brackets. Methods: In this study 40 freshly extracted upper first premolar human teeth were used and randomly divided into four groups (n=10), according to the type of the enamel surface treatment: I, acid etching; II, Er:YAG laser; III, Er:YAG laser + acid-etching; IV, sandblasting with aluminum oxide. The teeth were embedded in self cure acrylic in a vertical position so that the crowns were exposed. Stainless steel premolar brackets were bonded to all teeth with a standard procedure and all teeth were subjected to SBS test. The adhesive remnant index (ARI) was then evaluated for each specimen. Failure modes were assessed quantitatively under a stereomicroscope and morphologically under a scanning electron microscope (SEM). Statistical analysis was performed using oneway analysis of variance and the post hoc Tukey test, with the significance level set at 0.05. Results: Mean shear test values for each group were as follows: I, 10.21 ± 0.8; II, 9.33 ± 1.2; III, 13.46 ± 0.7; IV, 3.36 ± 0.6. While group III (ErYAG laser + acid-etched) showed the highest SBS values, group IV (sandblasting) showed the lowest SBS values and a ...

“…The glass ionomer cement has caught the interest of investigators because it is an extremely versatile material due to its properties, such as chemical bonding to enamel, minor polymerization shrinkage, coefficient of thermal expansion similar to that of the tooth structure, and fluoride release at long term to the dental enamel, thus presenting a cariostatic action 10,14,17,18,24 . Seppä and Forss 22 observed that fissures sealed with glass ionomer cement were more resistant to demineralization even after its macroscopic loss, possibly due to a combination between fluoride release to enamel and the presence of remaining material in the bottom of fissures.…”

RESUMOwww.fob.usp.br/revista or www.scielo.br/jaos bjetive -the aim of this study was to conduct an in vitro comparison of marginal microleakage (MM) and the depth of penetration (DP) of glass ionomer cements (GIC) and a resin sealant (RS) into occlusal pit and fissures. Methods -for that purpose, 60 intact third molars were equally distributed to 5 groups: G1 -37% phosphoric acid / Delton; G2 -40% polyacrylic acid / Ketac-Molar / nail varnish; G3 -Fuji Plus conditioner / Fuji Plus/ nail varnish; G4 -37% phosphoric acid / Vitremer / Finishing gloss; G5 -37% phosphoric acid / Vitremer prepared with a 1:4 ratio of powder / Finishing gloss. The teeth were submitted to a thermal treatment corresponding to 300 cycles (15 sec, 5/55 0 C), followed by complete coating with nail varnish, except for 1mm beyond the contour of the sealant. Afterwards, the teeth were immersed in 0.5% basic fuchsine for 24 hours. Thereafter, the teeth were sectioned in buccolingual direction and microscopically analyzed (150x magnification) by means of predetermined scores. The results were subject to the Kruskal-Wallis test. Results -there was no statistical difference between the materials tested in relation to the DP, being that all groups displayed nearly complete filling of the fissures. No sealant material was able to prevent dye penetration; however, the GICs provided better results of MM, with significant difference when compared to the RS. Conclusion -all materials investigated presented a satisfactory degree of penetration into the fissures; however, the glass ionomer cements displayed better performance in the marginal microleakage test compared to the resin sealant. Uniterms: Pit and fissure sealant; Glass ionomer cements; Marginal microleakage, penetration. EVALUATION OF MARGINAL MICROLEAKAGE AND DEPTH OF PENETRATION OF GLASS IONOMER CEMENTS USED AS OCCLUSAL SEALANTS AVALIAÇÃO DA MICROINFILTRAÇÃO MARGINAL E PROFUNDIDADE DE PENETRAÇÃO DOS CIMENTOS DE IONÔMERO DE VIDRO UTILIZADOS COMO SELANTES OCLUSAISbjetivo -o objetivo deste estudo foi comparar in vitro a microinfiltração marginal (MM) e o grau de profundidade de penetração (DP) de cimentos de ionômero de vidro (CIV) e um selante resinoso (SR) em fossas e fissuras oclusais. Materiais e Métodos -para tanto, 60 terceiros molares hígidos foram igualmente distribuídos em 5 grupos: G1-ácido fosfórico 37%/Delton; G2-ácido poliacrílico 40%/KetacMolar/esmalte cosmético; G3-Fuji Plus conditioner/Fuji Plus/ esmalte de cosmético; G4 -ácido fosfórico 37%/Vitremer/Finishing gloss; G5-ácido fosfórico 37%/Vitremer diluído na proporção de 1/4 de pó/Finishing gloss. Os dentes foram submetidos a um tratamento térmico correspondente a 300 ciclos (15 seg, 5/ 55 0 C), seguindo da total cobertura com esmalte cosmético, exceto 1mm além do contorno do material selador, sendo então imersos em solução de fucsina básica 0,5%, por 24 horas. Posteriormente, os dentes foram seccionados vestíbulo-lingualmente, e avaliados microscopicamente (aumento 150X), por meio de escores pré-determinados. Os resu...
