Aim: The aim of this study was to determine the temperature rise on the root surface and efficiency of different techniques in removing glass fiber posts.Material and Method: Thirty extracted premolar teeth were decoronated, instrumented and then obturated with gutta-percha and canal sealer. Post spaces were prepared, followed by cementation of glass fiber posts. The roots were divided into 2 groups n=15 . In group 1, a post removal kit, in Group 2 burlargo drill were used for removing the posts. To simulate a clinical environment, the teeth were embedded in polysiloxane and suspended over a heated water bath at approximately 370C. Thermocouple was placed on the external root surface. Removal times and temperature changes were recorded. The data were analyzed by ANOVA test.results: There were significant differences between the groups in terms of both time and heat p

Amaç: Bu çalışmanın amacı cam fiber postların uzaklaştırılmasında farklı tekniklerin etkinlikleri ve oluşan ısı artışının incelenmesidir.Gereç ve Yöntem: Otuz adet çekilmiş küçük azı dişinin kronları uzaklaştırıldı, kök kanalları genişletildi, güta-perka ve kanal patı ile dolduruldu. Post boşlukları hazırlandı, cam fiber postlar simante edildi. Kökler 2 gruba ayrıldı n=15 . Grup 1’de post uzaklaştırma kiti, grup 2’de frez-largo dril kullanılarak postlar uzaklaştırıldı. Klinik şartların taklit edilmesi için, dişler polisiloksan ölçü maddesine yerleştirilerek ve yaklaşık 370C’de ısıtılmış su banyosuna bırakıldı. Köklerin dış yüzeylerine ısı sensörü yerleştirdi, uzaklaştırma zamanları ve ısı değişimleri kaydedildi. Veriler ANOVA testi ile analiz edildi.Bulgular: Zaman ve ısı değişimi açısından iki grup arasında anlamlı farklılık bulundu p
