Abstract

The aim of this study was to evaluate the fracture resistance of posterior restorative materials applied to class II cavities prepared by different methods. Forty freshly extracted caries free human maxillary premolar teeth were used in this study. The teeth were randomly divided into 4 groups of each including 10 premolars. Group 1 was served as control and any treatment procedure was applied. The teeth in groups 2, 3 and 4 were respectively prepared as classical class II cavity, modified class II cavity and tunnel cavity. After completion of prepared cavities, the teeth were restored using a posterior composite resin (Dentsply, Kontstanz, Germany). All teeth were placed an Instron testing machine and the compressive force was applied at a crosshead speed of 1 mm/min until the fracture was occurred. The forces required to fracture the specimens were recorded as Newton. The obtained data was statistically evaluated by using one-way ANOVA and Tukey tests. The mean load necessary to fracture the samples in each group was (in N): Group 1: 828.23±118.21, Group 2: 779.32±139.99, Group 3: 799.82±117.26, Group 4: 805.39±108.68. There was no statistically significant difference between the groups (p>0.05). In the conclusion, it was found that use of different cavity design in restoration of the teeth was not affected the fracture resistance of the teeth.

Özet

Bu çalışmanın amacı; farklı yöntemlerle hazırlanan II. sınıf kavitelere uygulanan posterior restoratif materyallerin kırılma dayanıklılıklarının değerlendirilmesidir. Bu çalışmada 40 adet çürüksüz yeni çekilmiş insan premolar dişi kullanıldı. Dişler her bir grupta 10 adet diş olacak şekilde rastgele dört gruba ayrıldı. Grup 1 kontrol grubu olarak ayrıldı ve herhangi bir işlem uygulanmadı. Grup 2, 3 ve 4 teki dişlerde sırasıyla klasik sınıf II kavite, modifiye sınıf II kavite ve tünel kaviteler hazırlandı. Kavite preparasyonları hazırlandıktan sonra dişler posterior kompozit (Dentsply, Kontstanz, Germany) ile restore edildi. Örnekler Instron test cihazına bağlandı ve okluzal yüzeyleri kırılma görülene kadar 1mm/dk hızla sıkıştırma kuvvetlerine maruz bırakıldı. Örneklerin kırılması için gerekli olan sıkıştırma kuvvetleri Newton olarak kaydedildi. Elde edilen veriler tek yönlü varyans analizi ve Tukey testleri kullanılarak istatistiksel olarak analiz edildi. Her gruptaki örneklerin kırılması için gerekli ortalama kuvvetler şu şekilde belirlendi. Grup 1: 828.23±118.21, Grup 2: 779.32±139.99, Grup 3: 799.82±117.26, Grup 4: 805.39±108.68. Gruplar arasında istatistiksel olarak önemli bir farklılık bulunamadı (p>0.05). Sonuç olarak dişlerin restorasyonunda farklı kavite dizaynlarının kullanılmasının dişlerin kırılma dayanımında etkili olmadığı bulundu.
