Is this trial a fit for you?

Likely a good fit

Children aged 4 to 8 who have at least two restorable non-vital primary molars with periapical radiolucency and symptoms such as pain on chewing, pathological mobility, or internal/external root resorption are ideal candidates.

Probably not a fit

Children with systemic diseases, teeth near natural exfoliation, teeth with vital pulps, or teeth with furcation involvement extending to the developing permanent tooth germ are unlikely to benefit from this treatment.

What this trial studies

This interventional study compares Lesion Sterilization and Tissue Repair (LSTR) using a zinc oxide/6-gingerol mixture versus a conventional triple antibiotic paste in non-vital primary molars. Children aged 4–8 with at least two restorable non-vital primary molars and periapical radiolucency will receive minimal canal instrumentation followed by placement of one of the two medicaments. Clinical signs (pain on mastication, mobility, resolution of symptoms) and radiographic changes (periapical radiolucency, root resorption) will be recorded at scheduled follow-ups to compare healing. The trial is conducted at Al-Azhar University in Cairo to determine whether the zinc oxide/6-gingerol mix can match or improve outcomes compared with the antibiotic paste.

Why it matters

Potential benefit: If successful, this approach could provide a less invasive alternative that helps save infected baby molars and avoid extractions.

How similar studies have gone: Previous reports of LSTR using antibiotic mixtures have demonstrated clinical and radiographic success, while zinc- or herbal-based alternatives like 6-gingerol have been less extensively studied.
