Which two factors are critical during the sealant application process?

During the sealant application process, saliva control and moisture levels are indeed critical factors. Effective saliva control is vital because the presence of saliva can compromise the adhesion of the dental sealant to the tooth surface. If the area being sealed is wet or contaminated with saliva, it can prevent the sealant from bonding effectively, leading to premature failure of the sealant. Consequently, maintaining an ideal moisture level—essentially a dry field—ensures that the sealant adheres properly and provides optimal protection against dental caries.

Moisture control is often achieved through the use of suction devices and the careful placement of cotton rolls or gauze to help absorb saliva. Therefore, by focusing on these factors, dental assistants can significantly increase the effectiveness of the sealant application.

Other factors, such as the temperature of the material or type of light used, while having their roles in various dental procedures, do not have the same level of impact on the success of sealant applications as moisture control does.
