Abstract:

 Objective: The objective of this study was to evaluate the effect of various types of photopolymerization devices on the temperature of the pulp chamber during the adhesive bonding phase. Materials and Methods: To this purpose, cavities with a mesiodistal diameter of 5 mm, a buccolingual diameter of 3.5 mm, and a residual dentin thickness of 1.2 mm at the cavity base were prepared. Polymerization lights were applied for 20 seconds using three different devices. The temperature change within the pulp chamber was quantified using a thermocouple, with data collected at 10 and 20 seconds utilized for assessment. The mean intra-pulp temperature in the O-Light, Deepcure-L, and Valo groups at the 10th second was 39.9C, 41.1C, and 38.7C and at the 20th second, had temperatures of 42.4C, 44.3C, and 40.4C, respectively. Result:A statistically significant difference was observed between the Deepcure-L and Valo groups p  .01 in terms of maximum temperature, increase in pulp chamber temperature, and temperature at the 10th and 20th seconds. The observed changes in pulp chamber temperature between the groups, irrespective of light transmission type, are consistent with the power output of the devices, expressed in mWcm². All the groups yielded a temperature increase above the limit which has been described critical. Conclusion: During adhesive bonding phase, lower mWcm² devices could be preferred in cases where the remaining dentin thickness is reduced.

 Amaç: Bu çalışmanın amacı, adeziv uygulama aşamasında farklı tipteki fotopolimerizasyon cihazlarının pulpa odası sıcaklığı üzerindeki etkisini değerlendirmektir. Materyal ve Metot: Meziodistal çapı 5 mm, bukkolingual çapı 3.5 mm ve kavite tabanında kalan dentin kalınlığı 1.2 mm olan kaviteler hazırlandı. Polimerizasyon ışıkları üç farklı cihaz kullanılarak 20 saniye süreyle uygulandı. Pulpa odası içindeki sıcaklık değişimi bir termal sensör kullanılarak ölçüldü, 10 ve 20. saniyelerde toplanan veriler değerlendirme için kullanıldı. Bulgular: Pulpa içi ortalama sıcaklık 10. saniyede O-Light, Deepcure-L ve Valo grupları için sırasıyla 39,9C, 41,1C ve 38,7C, 20. saniyede ise 42,4C, 44,3C ve 40,4C bulundu. Deepcure-L ve Valo grupları arasında maksimum sıcaklık, pulpa odası sıcaklığındaki artış ve 10. ve 20. saniyelerdeki sıcaklık açısından istatistiksel olarak anlamlı bir fark gözlendi p.01. Sonuç: Gruplar arasında gözlenen pulpa odası sıcaklığı değişiklikleri, ışık iletim türünden bağımsız olarak, cihazların mWcm² cinsinden ifade edilen gücü ile tutarlıdır.
