Abstract

Aim: The treatment of internal resorption aims to remove necrotic pulp tissue, disinfect the canal, and fill the canal system, including the resorption zone. Warm gutta-percha techniques are commonly recommended for sealing resorption defects due to their flowable properties, but concerns about temperature rises during the obturation process remain. This study investigates the effect of remaining dentin thickness on temperature changes at the root surface during thermoplasticized gutta-percha obturation in simulated internal resorption cavities.
Materials and Methods: In the study, thirty maxillary central incisor teeth were used, and the teeth were split into two halves. A resorption cavity was created on one root half, while the other half was used as a control. The teeth were divided into three groups based on the remaining dentin thickness in the halves that contain the internal resorption cavity (0.4 mm, 0.7 mm, and 1 mm). Temperature changes during the thermoplastic gutta-percha obturation were measured using thermocouples. A paired samples t-test was used to assess the differences between the resorptive and control surfaces, and a one-way ANOVA test was applied to evaluate the temperature variations across the groups.
Results: Statistically significant temperature differences between the resorption and control surfaces were observed in all groups, but no significant differences were found among the three dentin thickness groups.
Conclusion: The study concludes that internal resorption cavities lead to higher temperature transmission at the root surface during thermoplasticized gutta-percha obturation, regardless of dentin thickness. However, no significant differences in temperature were observed among different dentin thicknesses.

İnternal Rezorpsiyon Kavitelerinin Termoplastik Gutta-Perka ile Doldurulması Sırasında Kök Yüzeyinde Oluşan Termal Değişiklikler Üzerinde Kalan Dentin Kalınlığının Etkisi

Abstract

Amaç: İnternal rezorpsiyon tedavisinin amacı nekrotik pulpa dokusunu uzaklaştırmak, kanalı dezenfekte etmek ve rezorpsiyon bölgesi de dahil olmak üzere kanal sistemini doldurmaktır. Sıcak güta perka teknikleri, akışkan özellikleri nedeniyle rezorpsiyon defektlerinin kapatılması için yaygın olarak önerilmektedir, ancak obturasyon işlemi sırasında sıcaklık artışları ile ilgili endişeler devam etmektedir. Bu çalışmada, simüle edilmiş internal rezorpsiyon kavitelerinde termoplastik güta perka obturasyonu sırasında kalan dentin kalınlığının kök yüzeyindeki sıcaklık değişimleri üzerindeki etkisi araştırılmıştır.
Gereç ve Yöntemler: Çalışmada otuz maksiller santral kesici diş iki yarım parçaya ayrılarak kullanıldı. Bir kök yarısında rezorpsiyon kavitesi oluşturulurken, diğer yarısı kontrol olarak kullanıldı. İnternal rezorpsiyon kavitesinde kalan dentin kalınlığına göre dişler üç gruba ayrıldı (0.4 mm, 0.7 mm ve 1 mm). Termoplastik gutta-perka ile doldurulması sırasında meydana gelen sıcaklık değişiklikleri thermocouple kullanılarak ölçüldü. Rezorpsiyonlu ve kontrol yüzeyleri arasındaki farkları değerlendirmek için eşleştirilmiş örneklem t-testi, gruplar arasındaki sıcaklık değişimlerini değerlendirmek için ise tek yönlü ANOVA testi kullanıldı.
Bulgular: Tüm gruplarda rezorpsiyonlu ve kontrol yüzeyleri arasında istatistiksel olarak anlamlı sıcaklık farkları gözlenmiştir, ancak üç farklı dentin kalınlığı grubu arasında kök yüzeyine ulaşan sıcaklık değerlerinde anlamlı bir fark bulunmamıştır.
Sonuç: Çalışma, internal rezorpsiyon kavitelerinin, termoplastik gutta-perka ile doldurulması sırasında kök yüzeyinde daha yüksek sıcaklık iletimine neden olduğunu, ancak dentin kalınlığına bağlı olarak sıcaklık farklarının anlamlı olmadığını ortaya koymaktadır.
