Dentists test deeper fillings to avoid gum surgery
NCT ID NCT07169305
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looks at a dental procedure called deep margin elevation (DME) for fixing cavities that go below the gum line. Researchers want to see if placing the filling slightly deeper than usual is safe for the gums and tooth nerve. They will treat 81 adults with deep cavities and check gum health, tooth health, and filling quality over time.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Deep Margin Elevation (a dental procedure using composite filling material)
- What this could lead to
- If successful, this could show that dentists can repair deep cavities without needing more invasive gum surgery, preserving tooth and gum health.
- What could go wrong
- This is a small, non-randomized trial with only 81 participants, so results may not apply to everyone. The procedure might still cause gum inflammation or other issues long-term.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patients at least 18 years of age at the time of treatment. * Permanent Posterior teeth exhibiting proximal caries lesion extending subgingivally below the cemento-enamel junction (CEJ). The axial extent of the caries should not be more than 75% of the dentin thickness. * Sound tooth structure of atleast 1mm should be present from the alveolar crest to the base of the cavity/ gingival seat after cavity preparation. * The tooth should either be asymptomatic or have reversible pulpitis as determined by history and pulp sensibility testing. There should be no history of spontaneous or lingering pain * Periodontally sound tooth * Full mouth plaque score (FMPS): ≤ 15% and Full mouth bleeding score (FMBS): ≤15% Exclusion Criteria: * Presence of bone disease (metabolic, endocrine, infectious, tumoral, developmental pathologies) * Pregnant or lactating and history of smoking or alcohol abuse * Anti inflammatory drug consumption within past 3 days * Uncontrolled or poorly controlled diabetes * Unstable Life threatening conditions or requiring antibiotic prophylaxis. * Presence of detectable plaque and Bleeding on probing on the tooth to be treated * Thin gingival biotype, Periodontitis and Gingival recession * Class II cavities with gingival margin above the CEJ * Previously restored teeth * Absence of adjacent tooth or antagonist or Crown in adjacent tooth. * H/o Bruxism, Xerostomia * Requiring gingivectomy * Isolation with rubber dam not possible
