As for this invention, it regards the hardening light/write device which can make the composite material for dentistry harden which has the expedient in order to blow the air. The air which is blown out from the hardening light/write device, is directed to the tooth which is disclosed to hardening light. As for the air which is blown out, the comfort of the patient and in order to maintain efficient hardening of the composite material for dentistry, it possesses the effect which cools the surface of the tooth.本発明は、空気を吹くための手段を持つ歯科用複合材料を硬化させることができる硬化ライト装置に関する。吹き出された空気は、硬化ライト装置から、硬化光に暴露される歯に向けられる。吹き出された空気は、患者の快適さおよび歯科用複合材料の効率的な硬化を維持するために、歯の表面を冷却する効果を有する。
