Official title: Deep Marginal Elevation and Its Impact on Periodontal Microenvironment: Microbiological, Clinical, and Radiographic Study

Run by Tanta University · NCT07156695 · Data updated 2026-11-12

This will test if raising the deep margin of a filling (DME) changes gum inflammation and nearby bone levels in adults with deep back-tooth cavities.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–60 with a Class II deep carious lesion requiring restoration, a healthy contralateral tooth, and willingness to attend follow-up visits are ideal candidates.

Probably not a fit

Patients with active periodontal disease, systemic conditions such as diabetes, recent anti-inflammatory medication use, pregnancy or lactation, or those without a healthy opposite tooth are unlikely to benefit from participation.

What this trial studies

This is a longitudinal clinical study of adults needing Class II restorations in which Deep Marginal Elevation (DME) will be performed and patients followed over time. Gingival crevicular fluid will be collected to measure inflammatory markers (e.g., IL-1β, TNF-α, MMP-8, PGE2, CRP) and microbiological profiles. Bitewing radiographs will be used to monitor crestal bone level and bone density changes, using the healthy contralateral tooth as an internal control. Participants with systemic disease, active periodontal infection, recent anti-inflammatory use, pregnancy, or lactation are excluded and follow-up visits are required to track outcomes.

Why it matters

Potential benefit: If successful, the findings could show that DME preserves gum and bone health while allowing durable restorations, potentially reducing the need for more invasive treatments.

How similar studies have gone: While DME is increasingly used in restorative practice, studies specifically linking DME to changes in periodontal inflammatory or microbiological markers are limited and not yet conclusive.
