Final answer:
Dentinal hypersensitivity can be reduced using toothpaste with ingredients like strontium chloride and potassium nitrate; good oral hygiene and specific compounds in toothpaste help prevent tooth decay and reinforce tooth structure.
Step-by-step explanation:
Blocking Dentinal Tubules with Restorative Materials:
Dentinal hypersensitivity is a common issue that can be alleviated by using toothpaste containing active ingredients like strontium chloride, potassium nitrate, arginine, and calcium sodium phosphosilicate (CSPS). These compounds help by blocking the dentinal tubules, reducing sensitivity. Additionally, a combination of arginine and CSPS has been found to have a superior effect in a clinical trial.
Mouthwashes with antiseptic properties contain compounds like thymol and eucalyptol that denature proteins and disrupt membranes. Dental abrasives, such as powdered white mica, provide a polishing action that can remove stains without contributing significantly to enamel erosion.
