| مستخلص: | Objective: The objective of this study was to evaluate the in vivo effectiveness of air spray to reduce pulp temperature rise during exposure of intact premolars to light emitted by a high-power LED light-curing unit (LCU). Methods and Materials: After local Ethics Committee approval (#255945), intact, upper first premolars requiring extraction for orthodontic reasons from five volunteers received infiltrative and intraligamental anesthesia. The teeth (n=9) were isolated using rubber dam, and a minute pulp exposure was attained. The sterile probe from a wireless, NIST-traceable, temperature acquisition system was inserted directly into the coronal pulp chamber. Real-time pulp temperature (PT) (°C) was continuously monitored, while the buccal surface was exposed to a polywave LED LCU (Bluephase 20i, Ivoclar Vivadent) for 30 seconds with simultaneous application of a lingually directed air spray (30s-H/AIR) or without (30s-H), with a seven-minute span between each exposure. Peak PT values were subjected to one-way, repeated-measures analysis of variance, and PT change from baseline (ΔT) during exposure was subjected to paired Student's t -test ( α =0.05). Results: Peak PT values of the 30s-H group were significantly higher than those of 30s-H/AIR group and those from baseline temperature ( p <0.001), whereas peak PT values in the 30s-H/AIR group were significantly lower than the baseline temperature ( p =0.003). The 30s-H/AIR group showed significantly lower ΔT values than did the 30s-H group ( p <0.001). Conclusion: Applying air flow simultaneously with LED exposure prevents in vivo pulp temperature rise. |
