Melatonin gel tested to help dental implants grip in infected sockets
NCT ID NCT07829393
First seen Sep 21, 2026 · Last updated Sep 21, 2026
Summary
Researchers are testing whether a topical melatonin gel helps dental implants stay stable when placed immediately into tooth sockets that had chronic infection. Sixty adults with non-restorable teeth and long-standing apical lesions will receive either standard implant placement with a bone graft or the same procedure plus melatonin gel applied to the implant and graft material. The team will measure implant stability over 12 months using a device that taps the implant, and will also track bone loss, bone density, pain, healing, infection, and implant survival.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- topical melatonin gel
- What this could lead to
- If it works, topical melatonin could become a simple add-on that helps dental implants hold firm in sockets that were infected, possibly reducing the need for extra surgery or waiting.
- What could go wrong
- This is a small, single-center study of 60 people, so results may not apply broadly. Melatonin gel might not improve implant stability, and placing implants into infected sockets carries a risk of infection or implant failure.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patients aged 18-50 years. * Non-restorable teeth associated with chronic apical lesions persisting after previous endodontic treatment and/or periapical surgery. * Adequate interarch relationship and interocclusal space for prosthetic rehabilitation. * Expected peri-implant jumping gap ≥2 mm. * Good oral hygiene and willingness to comply with follow-up visits. * The chronic periapical lesion of a predefined radiographic size range of \[4 - 10 mm\], measured as the maximum lesion diameter on preoperative CBCT. Exclusion Criteria: * Smokers. * Alcohol or drug abuse. * Pregnancy. * Systemic conditions contraindicating implant placement. * Bruxism or other parafunctional habits. * Inability or unwillingness to maintain oral hygiene or attend follow-up visits.
