[Consensus recommendations from Chinese experts on the standard operation procedure of curing light in direct composite resin adhesive restorations].

The curing light in direct composite resin adhesive restorations is a common technique and treatment method in oral clinic. It has many advantages, such as matching the color of the teeth, less removing the hard tissues of the teeth, resistance to abrasion, good masticatory performance and so on. It has almost replaced the traditional amalgam filling in the clinical dentistry repair. However, in clinical practice, improper use of the technique can also lead to increased loss of restorations and postoperative sensitivity. The reason is related not only to the physical and chemical properties of the material itself, but also the operator's lack of understanding and mastering the properties of the light cured material, especially the use rules of the light curing lamp. To this end, in September 2017, the vice chairman of Society of Cariology and Endodontology, Chinese Stomatological Association, professor Liang Jingping, organized a part of professional experts in this field, and invited the chief expert in 3M company, Dr. Joe Oxman, held a meeting about the use principle, operation mode and specification symposium of light curing lamp. Experts at the meeting had a very heated discussion, forming the following consensus.
