Secondary Outcome Measures

Name	Time	Method
Caries		Evaluate the efficiency of hydroxyapatite layer formation in the tooth cavity after caries removal and the feeling of usability by the operator.
Hypersensitivity		Evaluate the efficiency hydroxyapatite layer formation on the tooth surface with exposed dentin or wedge-shaped defects and the feeling of usability by the operator.
Discolored teeth		Evaluate the efficiency of forming a hydroxyapatite layer on the teeth, including at the cervical region, the lower solid void, and the contact point with the adjacent tooth and usability by the operator.
