The EquiaFil system was more successful than Riva SC regarding color match, marginal adaptation, anatomic form, and retention rate after a six-year clinical evaluation period.
Within the limitation of this study, we have foreseen that resin coating will protect and make the HVGIC materials as wear resistant as resin composites in clinical situations for a long time.
The aim of this study was to evaluate the roughness of the apical surface after apical resection performed by six different methods with an optical profilometer. Sixty human single root premolar teeth were used in this in vitro study. After root canal preparation, root canals were filled with gutta-percha and AH Plus root canal sealers by lateral condensation technique. The teeth were randomly divided into six groups according to the apical resection method: steel fissure bur, tungsten carbide fissure bur, Lindeman bur, diamond fissure bur, laser, and ultrasonic surgical piezo with a diamond tip. The root ends were resected 3 mm away from the root apex and at a 90 angle. The time required for apicectomy was recorded for each group. After apical resection, the root surfaces were analyzed by an optical profilometer. The Kruskal-Wallis method was used to analyze the differences between groups. The significance level was set at 5%. The roughest surfaces were obtained by laser (25.54 ± 9.01 μm) and Lindeman bur (17.35 ± 6.03 μm), respectively. The longest mean resection times were recorded in piezosurgery and laser surgery (57 ± 14.39 s and 50.9 ± 16.86 s), respectively. Although the diamond-tipped piezo surgical cutting time is long, it has the best results in terms of surface roughness (5.50 ± 1.73 μm). The optical profilometer is a more convenient tool for evaluating the surface after apical surgery, as it provides an opportunity to evaluate objectively with both visual and numerical data.
ÖZETGeleneksel kavite açma yönteminde, çürük ve çürükten etkilenmiş diş dokularının tamamen uzaklaştırılması esasken; günümüzde sağlıklı ve remineralize olma potansiyeli olan çürükten etkilenmiş diş dokularını kaldırmadan, sadece yumuşak ve denatüre çürük tabakasının uzaklaştırılması esasına dayanan minimal invaziv yaklaşım ön plana çıkmaktadır. Minimal invaziv yaklaşımın kabul görmesiyle birlikte, remineralizasyon potansiyeline sahip restoratif materyaller önem kazanmıştır. Günümüzde önemli olan sadece dişin restore edilmesi değil, restorasyon sonrası mevcut dokunun tekrar invaziv bir işleme gerek kalmaksızın uzun süreli korunmasıdır. Bu nedenle yapılacak olan restorasyonun estetik özelliklerinin yanı sıra, fiziksel ve mekanik özellikleri de büyük önem taşımaktadır. Cam iyonomer simanlar tanıtılmasından bu yana farklı klinik uygulamalar için kullanılmışlardır. Son zamanlarda daimi restorasyon materyali olarak amalgam ve kompozit rezinler yerine cam iyonomer simanların kullanılması fikri ön plana çıkmıştır. Bu derleme, restoratif materyal olarak kullanımı artmakta olan cam iyonomer simanlardaki yenilikleri bir arada sunmak amacıyla hazırlanmıştır. Kabul Tarihi: 24.12.2015
