A two-bottle self-curing universal adhesive (Tokuyama Universal Bond; Tokuyama Dental) that does not require a long waiting time or light curing after application of the bonding material has been developed. This study aimed to evaluate the influence of tooth and adhesive temperature during the bonding procedure on the effectiveness of dentin bonding. The results showed that the tooth temperature affected the effectiveness of the dentin bonding; therefore, to determine the precise bonding ability in the laboratory, the temperature of the tooth must be raised until it is the same as that of the oral cavity. In addition, the temperature of the material did not affect bonding effectiveness; this result confirms that it does not matter whether the refrigerated product is used soon after its removal from the refrigerator or after it reaches room temperature in the clinic.
一种无需长时间等待或在应用粘结材料后进行光照固化的双瓶自固化通用粘结剂（日本特科尼卡公司的 Tokuyama Universal Bond）已经被开发出来。本研究旨在评估粘结过程中牙和粘结剂温度对牙本质粘结效果的影响。结果表明，牙温度会影响牙本质粘结效果；因此，为了在实验室中确定准确的粘结能力，必须将牙温度升高至与口腔温度相同。此外，材料温度不会影响粘结效果；这一结果证实，从冰箱中取出后或在临床环境中达到室温后，使用冷藏产品并不重要。
