Evaluation of the Effect of DifferentCuring Units and Exposure Times onPulp Chamber Temperature UsingSimulated Pulpal Microcirculation
Öz: Objective: To compare the elevations in physiological pulp chamber temperature and blood microcirculation during light curing using four different light sources at two different exposure times.Materials and Methods: The study was performed on eighty Class-V cavities divided into eight groups of ten experiments each, according to the curing unit and exposure time. Short-term curing was performed in four groups: quartz-tungstenhalogen (QTH)-20 seconds (s) (XL3000, 3M ESPE, St. Paul, MN, USA); Woodpecker (WP)-15s (Lux V Light Cure Unit, WP, Apexion Dental Products); KR-10s (Demi Plus Dental Curing Light, Kerr Dental) and VL-3s (VALO light-emitting diode Curing Light Xtra Power mode, Ultradent Products, South Jordan, UT, USA). The same units were used for long-term curing at double the exposure time (i.e., QHT-40s, WP-30s, KR20s, VL-3+3s). Composite material (Filtek Ultimate, 3M/ESPE) was placed into the cavities, followed by light curing performed at a distance of 1 mm. Temperature changes in the pulp chamber were recorded. The Kruskal-Wallis test, followed by Mann-Whitney U multiple comparisons test, were used for statistical analyses, with p<0.001 considered to be statistically significant.Results: There were no significant differences among the curing units at the same exposure times. However, increases in pulp chamber temperatures varied significantly depending on the curing time (p<0.001). All the curing units induced significantly higher intrapulpal temperature changes at long-term curing times, except the WP groups (p<0.001). WP-30s, KR-20s and VL-3+3s exhibited critical temperature increases >5.5 °C.Conclusion: Longer curing times led to critical temperature increases in the pulp chamber. Shorter curing times can protect the pulp tissue against damage caused by temperature elevations above a certain threshold
Anahtar Kelime: Yapay Pulpal Mikrosirkülasyonu Kullanılarak Farklı Işınlama Üniteleri ve Işınlama Sürelerinin Pulpa Odası Sıcaklığına Etkisinin Değerlendirilmesi
Öz: Amaç: İki farklı ışınlama süresinde dört farklı ışık kaynağı kullanılarak ışıklasertleştirme sırasında fizyolojik kan mikrosirkülasyonu ile birlikte pulpa odasısıcaklık artışlarını karşılaştırmak. Gereç ve Yöntemler: Çalışma, farlı ışık kaynakları ve farklı ışınlama süresine göre, her biri 10 deneyden oluşan sekiz grupla seksenSınıf-V kavite üzerinde gerçekleştirilmiştir. Kısa süreli kürleme dört grupta gerçekleştirildi: kuvars-tungsten-halojen (QTH) 20 saniye(XL3000, 3M ESPE, St. Paul, MN, ABD); Woodpecker (WP) -15s (Lux V Işık Tedavi Ünitesi, WP, Apexion Dental Ürünleri); KR-10s (DemiPlus Dental Kür Işık, Kerr Dental); ve VL-3s (VALO ışık yayan diyot Kür Işık Xtra Güç modu, Ultradent Ürünler, South Jordan, UT, ABD).Aynı birimler, pozlama süresinin iki katı uzun süreli ışınlama için kullanılmıştır (yani, QHT-40s, WP-30s, KR-20s, VL-3+3s). Kompozitmalzeme (Filtek Ultimate, 3M/ESPE) boşluklara yerleştirildi, ardından 1 mm mesafede ışıkla sertleştirme yapıldı. Pulpa odasındakisıcaklık değişimleri kaydedildi. Kruskal-Wallis testi, ardından Mann-Whitney U çoklu karşılaştırma testi uygulanmış, istatistikselanalizlerde p<0,001 istatistiksel olarak anlamlı bulunmuştur. Bulgular: Aynı ışınlama süreleri içerisinde ışınlama cihazları arasında önemli bir farklılık yoktu. Bununla birlikte, pulpa odasısıcaklıklarındaki artışlar, ışınlama süresine bağlı olarak önemli ölçüde değişmiştir (p<0,001). Tüm sertleştirme üniteleri, WP gruplarıhariç, uzun süreli ışınlama sürelerinde, önemli ölçüde daha yüksek sıcaklık değişikliklerine neden olmuştur (p<0,001). WP-30s, KR-20sve VL-3+3s, > 5,5 °C kritik sıcaklık artışları sergiledi. Sonuç: Daha uzun ışınlama süreleri, pulpa odasındaki kritik sıcaklık artışlarına yol açmıştır. Daha kısa ışınlama süreleri, pulpayı belirlibir eşiğin üzerindeki sıcaklık yükselmelerinin neden olduğu hasara karşı koruyabilir.
