Diş Beyazlatma Sırasında Kullanılan Aktivatör Işınların Pulpa Üzerindeki Sıcaklık Artışına Etkisi

Amaç: Bu çalışmanın amacı, çeşitli ışık kaynakları kullanarak yapılan diş beyazlatma işlemi sırasında beyazlatma jeli varlığında ve yokluğunda pulpa odasındaki sıcaklık artışını değerlendirmektir. Yöntem: Çalışmada 20 adet yeni çekilmiş insan dişi kullanıldı. Kuartz tungsten halojen ışık kaynağı, LED ışık kaynağı ve diode Lazer ışık kaynağı kullanılarak beyazlatma ajanı (%36 H2O2) varlığında ve yokluğunda olmak üzere dişler 15 dakika boyunca ışığa maruz bırakıldı ve oluşan pulpa odası sıcaklık artışları kaydedildi. Veriler Paired Simple test, Univariate Analysis of Varianca ( ANOVA ), Dependet Variable Test ve Tukey ' s honestly significant difference ( HSD ) ile istatistiksel olarak analiz edildi. Bulgular: Diode lazer ışık kaynağı en yüksek ışı artışına neden oldu. LED ışık kaynağı ise en düşük ısı artışına neden oldu. İstatistiksel analizler ışık kaynakları arasında, sıcaklık artışında istatistiksel olarak anlamlı derecede farklılık olduğunu gösterdi (P=.000). Sonuç: Araştırmamıza göre, LED ve halojen ışık kaynakları pulpada ısı artışına neden olmuştur fakat bu artış pulpa dokusunda geri dönüşümsüz zararlı değişikliğe neden olacak seviyede değildir. Fakat, diode lazer ışık kaynağı kullanıldığında fazla ısı artışı olabilmesi nedeniyle dikkatli olunması gerekir. Bu sonuçlar, diş tiplerinden ve beyazlatma ajanı varlığından etkilememiştir

The Effect Of Light-Activated Bleaching On Increase Of Pulp Chamber Temperatures

Objectives: The purpose of this study was to evaluate the pulp chamber temperature rise during a tooth whitening procedure using various light sources. Methods: Twenty freshly extracted human teeth were used for study. All tooth irradiated for 15 minutes with quartz tungsten halogen, LED and diode laser activation lamps, and temperature rise of pulp chamber were recorded with and without bleaching agent (%36 H2O2). Data were analyzed statistically by the Paired Simple test, Univariate Analysis of Variance (ANOVA), Dependent Variable Test and Tukey's honestly significant difference (HSD). Results: Diode laser light source led to highest increase in pulp chamber temperatures and LED light source caused minimum increase in pulp temperatures. The statistics analysis showed that there were statistically significant difference among light sources (P=0.000). Conclusion: According to the present study, the temperature increases recorded for LED and Halogen light sources but it were not caused irreversible harmful changes in pulp tissue. However, Diode Laser-generated much temperature rise so caution is advised. These results weren't affected by neither bleaching agent present nor tooth types
