Bulk-Fill restorative materials in primary tooth: An intrapulpal temperature changes study

Objectives: It was aimed to investigate the temperature changes in primary teeth pulp chamber during the curing/setting of bulk-fill restorative materials with different nanoparticle contents. Methods: Twenty-five extracted, primary mandibular second molars were prepared as a Class II cavity. Five bulk-fill restorative materials consisting of Equia Fil (HVGIC), glass carbomer (GC) cement, Sonic Fill (SF), X-tra Fil (XF), and Quix Fil (QF) were tested. The measurement of the pulp chamber temperature changes (starting temperature 37°C) during setting/curing was performed with a J type thermocouple. The data, differences between highest and initial temperature values, were recorded and analyzed by one-way ANOVA. Results: The temperature changes in the pulp chamber were in EF (2.81°C), GC (7.92°C), SF (3.33°C), XF (3.43°C), and QF (3.02°C). There were statistically significant differences between temperature changes in groups (P < 0.05). Conclusion: The tested bulk-fill resin composites and high-viscosity glass ionomer cement do not increase the intrapulpal temperature in primary teeth during the curing/setting.

Farkli yüzey hazirlama yöntemlerinin fissür örtücülerin bağlanma dayanimi üzerine olan etkisi

Amac: Bu calismada amaci kurutma ajani/ kurutma ajani olmaksizin mine yuzeyinin hazirlanmasinda asitle puruzlendirme ve Er:YAG lazerin (QSP ve MSP mod) fissur ortucunun baglanma dayanimi uzerine etkisini degerlendirmek amaclandi. Gerec ve Yontemler: Bu calismada 30 adet curuksuz daimi dis kullanildi. Disler mine-sement sinirinin 2 mm ustunden kesildi ve kokler uzaklastirildi. Disler meziodistal olarak ikiye ayrildi. Elde edilen 60 yarim dis akrilik recine icine gomuldu. Mine yuzeyinde fissure ortuculer icin 2 mm capinda alan olusturuldu. Butun gruplara Ultraseal XT plus (Fissur ortucu:FO) uygulandi. Ornekler randomize olarak 6 gruba ayrildi (n:10); G1:% 37 fosforik asit + Prima Dry + FO, G2:% 37 fosforik asit + FO, G3: Er: YAG (MSP modu) + Prima Dry + FO; G4: Er: YAG (MSP modu) + FO; G5: Er: YAG (QSP modu) + Prima Dry + FO; G6: Er: YAG (QSP modu) + FO. Ornekler 24 saat distile su icinde bekletildikten sonra baglanma kuvvetleri, universal test makinesi ile test edildi. Verileri karsilastirmak icin Kruskal-Wallis ve Mann-Whitney U-testi kullanildi. Bulgular: Gruplara ait baglanma dayanimlari soyledir (MPa) G1: 11.33, G2: 9.76, G3: 8.65, G4: 7.72, G5: 4.49, G6: 2.73. Gruplar arasinda istatistiksel fark oldugu gozlendi (p < 0.05). Sonuc: Mine yuzeyine asit uygulamasi, Er:YAG lazer QSP ve MSP moda gore daha iyi sonuclar verdigi gorulmustur. Fissur ortucu uygulanmadan once kurutma ajani uygulanabilir.
