Question

What step should the dental assistant take before applying topical fluoride?

Answer 1

Prior to the application of topical fluoride, a dental assistant must clean the patient's teeth to remove any plaque and ensure effectiveness of the fluoride treatment. Fluoride is fundamental in dental health as it forms less soluble fluorapatite in the enamel and has bacteriostatic effects that reduce decay.

Step-by-step explanation:

Before applying topical fluoride, a dental assistant should ensure that the patient's teeth are clean and free from plaque and debris. This involves professional teeth cleaning, which might include scaling and polishing. Removal of plaque and debris allows for better adherence of the fluoride to the enamel, making the treatment more effective. It is important to understand that fluoride is crucial in preventing dental caries, as it enhances the remineralization of tooth enamel and impedes the actions of bacteria that cause decay.

Fluoride's action includes incorporation into tooth enamel where it forms fluorapatite, which has a higher resistance to acid. Community water fluoridation is another preventive measure used to maintain an optimal level of fluoride in drinking water to support oral health. In addition to professional applications of fluoride, daily oral hygiene practices, including brushing with fluoride toothpaste and using fluoride mouthwash, contribute significantly to the prevention of tooth decay.

Answer 2

Before applying topical fluoride, the dental assistant must ensure the patient's teeth are clean through a thorough prophylaxis, removing plaque and tartar for an optimal surface for fluoride treatment.

Step-by-step explanation:

Before the application of topical fluoride, it is crucial for the dental assistant to conduct a comprehensive prophylaxis to guarantee optimal effectiveness of the fluoride treatment. Prophylaxis involves the removal of plaque and tartar from the patient's teeth, ensuring a clean and smooth surface for the topical fluoride to adhere to. This step is essential as plaque and tartar can act as barriers, hindering the direct contact of fluoride with the tooth enamel.

The first step in prophylaxis is scaling, where the dental assistant uses hand instruments or ultrasonic scalers to remove tartar (calculus) from the tooth surfaces. Following scaling, the dental assistant performs a thorough polishing using a prophylaxis paste. This polishing step not only enhances the esthetics of the teeth by removing stains but also creates a polished enamel surface. A smooth enamel surface is vital for optimal fluoride penetration during the subsequent treatment.

By ensuring a clean and debris-free tooth surface through prophylaxis, the dental assistant maximizes the efficacy of the topical fluoride application. This approach promotes the absorption of fluoride into the enamel, aiding in the prevention of dental caries and reinforcing the overall oral health of the patient. The combination of prophylaxis and topical fluoride application serves as a preventive measure, contributing to the maintenance of strong and healthy teeth
