Is this trial a fit for you?

Likely a good fit

Children aged 5–8 with restorable non-vital primary molars showing signs such as spontaneous pain, deep caries reaching the pulp, chronic abscess, or a draining sinus are ideal candidates.

Probably not a fit

Children who are uncooperative, allergic to antibiotics, or whose teeth have advanced physiological root resorption, severe internal resorption, canal obliteration, or other exclusions are unlikely to benefit from enrollment.

What this trial studies

This is a randomized, double-blinded, parallel-controlled Phase 2 trial enrolling 60 children with non-vital primary molars to compare lesion sterilization and tissue repair (LSTR) using either triple antibiotic paste (ciprofloxacin + metronidazole + cefixime) or simvastatin paste. After non-instrumentation cleaning, the allocated medicament will be placed, the tooth sealed with glass ionomer cement, and a stainless steel crown fitted. Clinical and radiographic outcomes will be recorded at 1, 2, and 3 months, with primary endpoints including absence of pain, swelling, or sinus tract and radiographic signs of healing. The trial is conducted at Dow International Dental College, Karachi, and aims to offer an antibiotic-sparing alternative if simvastatin proves effective.

Why it matters

Potential benefit: If successful, simvastatin could provide an effective, antibiotic-sparing option to promote healing of infected primary molars.

How similar studies have gone: LSTR using triple antibiotic paste has clinical precedent, while the use of simvastatin in this setting is relatively novel with limited clinical data so far.
