Evaluating In Vitro Performances of Various Pit and Fissure Sealing Materials

Öz

Objectives: The aim was to evaluate the penetration depth and microleakage of a resin infiltrant (Icon, DMG), and two fissure sealants (Glass Carbomer, GCP Dental; Teethmate F-1, Kuraray) applied onto pits and fissures in vitro. Materials and Methods: 90 human molars were used for penetration test. Teeth stored in 0.1% TRITC for 24 hours to label all accessible pores. Materials were labeled with 0,1% RITC before applying. Pieces were obtained from each tooth perpendicularly and examined with a confocal microscope (n=20). Maximum depth of penetration (maxPD) and of lesion (maxLD) were measured, and the maximum percent penetration was calculated (maxPDY). 30 molars were used for microleakage test. Teeth were kept in basic fuchsin dye for 24 hours. Teeth were divided in the mesiodistal direction, pieces were examined with a stereomicroscope and scored (n=10). Kruskal-Wallis and Mann-Whitney U tests were used for the statistical analysis (p=0.05). Results: The maxPD values of the Icon group was statistically higher than the Glass Carbomer and the Teethmate F-1 groups (p<0.05). The maxPD values of Glass Carbomer and the Teethmate F-1 groups were similar (p>0.05). Glass Carbomer group showed severe microleakage values and internal cracks. There was no difference between Icon and Teethmate F-1 groups statistically (p>0.05). Conclusion: Icon and Teethmate F-1 groups displayed favorable performance. Although the penetration depth of the Glass Carbomer is similar to Teethmate F-1 group, further research on the clinical performance of this material is needed due to its excess microleakage.

Amaç: Bu çalışmanın amacı, pitlere ve fissürlere uygulanan bir infiltrantın (Icon, DMG) ve iki fissür örtücünün (Glass Carbomer, GCP Dental; F1-Teethmate, Kuraray) penetrasyon derinliğini ve mikrosızıntısını in vitro olarak değerlendirmektir. Gereç ve Yöntemler: Penetrasyon testi için, 90 adet insan azı dişi kullanıldı. Erişilebilir tüm gözenekleri işaretlemek için dişler 24 saat boyunca %0,1 TRITC' de bekletildi. Materyaller uygulanmadan önce %0,1 RITC ile işaretlendi. Her dişten dik kesitler alınarak konfokal mikroskopta incelendi (n=20). Maksimum penetrasyon derinliği (maxPD) ve lezyon derinliği (maxLD) ölçüldü ve maksimum penetrasyon yüzdesi hesaplandı (maxPDY). Mikrosızıntı testi için, 30 adet molar diş kullanıldı (n=10). Dişler 24 saat bazik fuksin boyasında bekletildi. Dişlerden meziodistal yönde kesitler alınarak stereomikroskopta incelendi ve skorlandı (n=10). İstatistiksel analizde Kruskal-Wallis ve Mann-Whitney U testleri kullanıldı (p=0,05). Bulgular: Icon grubunun maxPD değerlerinin Glass Carbomer ve Teethmate F-1 gruplarına göre istatistiksel olarak daha yüksek olduğu görülmüştür (p<0,05). Glass Carbomer ve Teethmate F-1 gruplarının maxPD değerleri benzerdi (p>0,05). Glass Carbomer grubu ciddi mikrosızıntı değerleri ve içsel çatlaklar gösterdi. Icon ve Teethmate F-1 grupları arasında istatistiksel olarak anlamlı fark yoktu (p>0,05). Sonuç: Icon ve Teethmate F-1 grupları istenen performansı göstermiştir. Glass Carbomer'in penetrasyon derinliği Teethmate F-1 grubuna benzer olsa da mikrosızıntısının fazla olması nedeniyle bu materyalin klinik performansı konusunda daha fazla araştırmaya ihtiyaç vardır.
