The Effect of Air-abrasion on the Shear-Bond Strength of Composite Resins on Enamel and

Abstract

The purpose of this study was to evaluate the effect of air-abrasion on the shear bond strengths of a flowable Tetric-Flow , a packable Surefil , a hybrid Charisma and an organic modified ceramic based Admira composite resins. 160 extracted human maxillary anterior teeth were used. The teeth were randomly divided into four groups, each containing 40 teeth. Group 1: Buccal enamel surfaces were ground by using 600 grit silicon carbide abrasive discs Group 2: Buccal enamel surfaces were airabraded for 6 seconds by using an air-abrasive unit with 27µm aluminum oxide particles at 120 psi pressure. Group 3: The enamel was removed by using a diamond bur and the buccal surfaces of dentin were ground by using 600 grit silicon carbide abrasive discs Group 4: The enamel was removed by using a diamond bur and the buccal surfaces of dentin were air-abraded for 6 seconds by using an air-abrasive unit with 27µm aluminum oxide particles at 120 psi pressure. The teeth in each group were also randomly divided into four groups of four different composite resins each containing 10 teeth. Restorative materials were applied on flat enamel and dentin surfaces by a celluloid cylindirical matrix diameter of 3 mm, height of 4mm according to the manufacturers’ instructions and polymerized by a lightcuring unit for 40 s. The restored specimens were stored in distilled water for 24 hours at 37ºC and subjected to thermocycling for 200 cycles between 5±2ºC and 55±2ºC. Shear bond strengths were determined using a Universal testing machine at a crosshead speed of 0,5 mm/per minute. Control groups showed statistically significant higher shear bond strengths than air-abraded groups p

Abstract

Bu çalışmanın amacı; air-abrazyonun birakıcı Tetric-Flow , bir kondanse edilebilir Surefil , bir hibrit Charisma ve bir organik modifiye seramik esaslı Admira kompozit rezininmine ve dentine makaslama bağlanma dayanımlarıüzerine etkisini değerlendirmektir. 160 adet çekilmiş maksiller anterior insan dişi kullanılmıştır.Dişler her bir grup 40 diş içerecek şekilde rastgele4 gruba ayrılmıştır.Grup 1: Bukkal mine yüzeyleri 600 grit silikonkarbit aşındırıcı disklerle pürüzlendirilmiştir Grup 2: Bukkal mine yüzeylerine 120 psi bas›nç ve 27µm alüminyum oksit partiküllere sahip air-abraziv cihaz› ile 6 saniye air-abrazyon uygulanm›şt›r. Grup 3: Mine elmas bir frez yard›m›yla kald›r›lm›ş ve dentindeki bukkal yüzeyler 600 grit silikon karbit aş›nd›r›c› disklerle pürüzlendirilmiştir. Grup 4: Mine elmas bir frez yard›m›yla kald›r›lm›ş ve dentin yüzeylerine 120 psi bas›nç ve 27µm alüminyum oksit partiküllere sahip airabraziv cihaz› ile 6 saniye air-abrazyon uygulanm›şt›r. Daha sonra her bir gruptaki dişler 4 farkl› kompozit rezini içerecek şekilde 10’ar dişten oluşan 4 gruba ayr›lm›şlard›r. Bir sellüloid silindirik matrix 3 mm çap›nda 4 mm yüksekliğinde ile restoratif materyaller üretici firma tavsiyesine uyularak düz mine ve dentin yüzeylerine uygulanm›ş ve 40 saniye ›ş›k cihaz› ile polimerize edilmişlerdir. Örnekler 37 ºC’de 24 saat distile suda bekletildikten sonra 200 kez 5±2 ºC ve 55±2 ºC’ termal siklus işlemine maruz b›rak›lm›şlard›r. Daha sonra başl›k h›z› 0,5 mm/dak olan Universal test makinesi ile makaslama dayan›mlar› tespit edilmiştir. Hem mine hem dentinde kontrol gruplar› airabrazyon yap›lan gruplardan istatistiksel olarak anlaml› seviyede daha yüksek makaslama bağlanma dayan›m› göstermiştir p
