ClinConnect Summary
This clinical trial is studying how vitamin D supplements can help improve dental health, specifically in people who have early signs of tooth decay known as Initial Carious Lesions. Researchers want to see if vitamin D can prevent these lesions from getting worse compared to using fluoride treatments. Participants will be divided into three groups: one group will receive vitamin D supplements and tips on oral hygiene; another group will get both vitamin D and fluoride treatments along with hygiene tips; and the last group, who already have enough vitamin D, will only receive fluoride and hygiene tips. The study will last for six months, during which researchers will monitor changes in tooth health and the types of bacteria present in saliva.
To be eligible for the trial, participants should be between 12 and 50 years old, have at least two teeth with early signs of decay, and have a vitamin D deficiency. Some individuals may not qualify, including those with certain gum diseases, severe health issues affecting vitamin D, or those currently using specific dental products. This study is actively recruiting participants, and it aims to provide insights into how vitamin D might be an effective way to support dental health in those at risk of decay.
