What this trial studies

This clinical trial investigates the prevention of dental caries by assessing genetic risk factors and saliva immunodeficiency in adolescents undergoing orthodontic treatment. A total of 2000 adolescents will be screened, with 520 selected for a randomized controlled trial comparing intensive prevention strategies against traditional methods. Participants will be genotyped to categorize them into susceptible and non-susceptible groups, and clinical outcomes will be measured at multiple time points using various diagnostic techniques. The study aims to develop personalized oral care strategies based on genetic predisposition.

Who should consider this trial

Good fit: Ideal candidates are adolescents undergoing orthodontic treatment with fixed multibrackets appliances.

Not a fit: Patients with impacted canines, agenesis in the frontal region, or those who have undergone maxillofacial surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective, personalized prevention strategies for dental caries in adolescents.

How similar studies have performed: Other studies have shown promise in using genetic factors for personalized medicine, but this specific approach to caries prevention is relatively novel.
