目的：活髓牙预备可能对牙髓造成不可逆的热损伤。牙科布尔斯的制造技术可以减少热量产生并最小化对牙髓的过热和创伤的风险。Strauss（Raanana，以色列）推出了“优质”金刚石布尔斯钻，声称其具有上级效率和寿命。我们试图通过比较“标准”和“高级”布尔斯钻引起的髓内温度升高来确定最安全的准备方法。方法和材料：在离体人牙上测试了三种类型的金刚石布尔斯（F1 R、F21 R和K2）（每种磨头类型n = 8颗牙齿）。对每种钻头类型的优质和标准制造技术进行了比较（每组n = 24颗牙齿;共48颗牙齿）。在手术过程中，使用牙髓内热电偶测量温度。比较采用t检验和单因素方差分析。P
Objective: Vital tooth preparations may cause irreversible thermal damage to the pulp. The manufacturing techniques of dental burs may decrease heat production and minimize the risk of overheating and trauma to the dental pulp. Strauss (Raanana, Israel) has introduced "premium" diamond burs, claiming superior efficiency and longevity. We sought to determine the safest preparation methods by performing a comparison of intrapulpal temperature increases caused with "standard" and "premium" burs. Method and Materials: Three types of diamond burs (F1R, F21R, and K2) were tested on extracted human teeth (n = 8 teeth per bur type). Premium and standard manufacturing techniques were compared for each bur type (n = 24 teeth per group; total 48 teeth). An intrapulpal thermocouple was used to measure the temperature during the procedure. Comparisons were analyzed with the t test and one-way ANOVA. P
