Public Health Dentistry

The number of patients required in a clinical trial to treat a specify disease increases as:

1. the incidence of the disease decreases.
2. the significance level increases.
3. the size of the expected treatment effect increased.
4. the drop-out rate increases.

📠Explanation:

A higher drop-out rate can reduce the power of a study, as it leads to a smaller sample size and potentially less reliable results. To maintain the statistical significance and power of the study, a larger sample size must be enrolled initially to account for the expected number of participants who will not complete the study. Other factors that influence sample size include the incidence of the disease, the significance level, and the size of the expected treatment effect, but the question specifically asks about the impact of an increasing drop-out rate.

0.05% sodium fluoride solution = 225 ppm fluoride

0.2% sodium fluoride solution = 900 ppm fluoride
