What this trial studies

This clinical trial compares the effectiveness of two root canal filling materials in treating necrotic primary molars in children aged 5-7. One group will receive a traditional zinc oxide eugenol-based sealer, while the other will receive a modified mixture containing antibiotics and simvastatin. The study aims to assess clinical and radiographic outcomes to determine which treatment better preserves the affected teeth and supports overall dental health. The trial will include children with specific eligibility criteria related to their dental condition and overall health.

Who should consider this trial

Good fit: Ideal candidates are children aged 5-7 with necrotic primary molars and no systemic diseases.

Not a fit: Patients with non-restorable molars or those with known allergies to antibiotics or anti-hyperlipidemia drugs may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the success rate of preserving primary molars, enhancing children's dental health and function.

How similar studies have performed: Previous studies have shown promising results with similar approaches using antibiotic mixtures in endodontics, indicating potential for success.
