Objectives: The aim of this in vitro study was to evaluate the fracture resistance of endodontically treated upper premolar teeth restored with different resin composites.
Materials and Methods: Hundred and eight maxillary premolar teeth were randomly divided into nine groups (n=12). The teeth in the first group were left intact and tested as unprepared group 1 (negative control) (group 1). Other eight groups were prepared with MOD cavities and endodontically treated. The teeth in group 2 (positive control) were unrestored. Other groups were restored with different resin composites. Group 3: conventional resin composite and group 4-9 six bulk fill resin composite (group 4: 3M Filtek Flowable Bulk Fill, group 5: 3M Filtek Posterior Bulk Fill, group 6: Voco X-tra base, group 7: Voco X-tra fil, group 8: Dentsply SDR Flow, group 9: Dentsply Quixfil). Single Bond Universal was applied as self-etch, according to application instructions. The restored teeth were stored in distilled water for 24 hours at 37°C. Compressive force was applied parallel to the long axis of the teeth. The test was carried out at a speed of 1mm/min. ANOVA and Tukey HSD tests were used in the analysis of the data (p,0.05).
Results: Conventional resin composite (group 3) showed lower fracture resistance than bulk fill resin composites (p<0.05) . There was no significant difference between the groups restored with bulk fill composites (p≥0.05).
Conclusions: The bulk fill composites increase the fracture resistance of endodontic treated teeth,
Amaç: Bu in vitro çalışmanın amacı, farklı tip kompozit rezinler ile restore edilmiş endodontik tedavi görmüş üst premolar dişlerin kırılma direncini değerlendirmektir.
Gereç ve Yöntemler: Yüz sekiz maksiller premolar diş rastgele dokuz gruba (n=12) ayrıldı. Birinci gruptaki dişler (grup I) negatif kontrol grubu olarak belirlendi ve herhangi bir preparasyon yapılmadı. Kalan sekiz gruptaki dişlere MOD preparasyonlar hazırlandı ve endodontik tedavi yapıldı. Sekiz gruptan biri (grup 2) pozitif kontrol grubu olarak seçildi ve dişlere koronal restorasyon yapılmadı. 3. grup (3M UR200) geleneksel kompozit rezin ile restore edildi. Geri kalan 6 grup ise (4. grup 3M Filtek Flowable Bulk Fill, 5.grup 3M Filtek Posterior Bulk Fill, 6.grup Voco X-tra base, 7.grup Voco X-tra fil, 8.grup Dentsply SDR Flow, 9.grup Dentsply Quixfil) altı farklı bulk fill kompozit rezin ile restore edildi. Restorasyonlarda adeziv olarak Single Bond Universal, uygulama talimatlarına göre self-etch olarak uygulandı. Restore edilen dişler distile suda 37°C'de 24 saat saklandı. Örnekler üniversal test cihazında 1mm/dak hızda kırıldı. Veriler, tek yönlü Anova ve post hoc Tukey HSD testi kullanılarak analiz edildi. Analizler, SPSS 20.0 programı ile %5 anlamlılık düzeyinde gerçekleştirildi.
Bulgular: Birinci grupta elde edilen skorlar diğer gruplara göre anlamlı ölçüde daha yüksek bulundu (p<0,05). Bulk fill kompozit rezinler ile restore edilen gruplar arasında kırılma direnci açısından anlamlı farklılık bulunmadı (p>0,05). En düşük kırılma skorları ise pozitif kontrol grubunda görüldü (p<0,05).
Sonuçlar: Bulk fill kompozit ile restore edilen endodontik tedavili dişlerin kırılma direnci skorları, geleneksel kompozit rezinler ile restore edilen dişlerden daha yüksek bulunmuştur.
