A Comparative Clinical Assessment of Adjunctive Hyaluronic Acid With 3D Printed Versus Milled CAD CAM Provisional Dental Restorations on Active Periodontal Status and Surface Roughness and Biocompatibility

A Comparative Clinical Assessment of Adjunctive Hyaluronic Acid With 3D Printed Versus Milled CAD CAM Provisional Dental Restorations on Active Periodontal Status and Surface Roughness and Biocompatibility (A Randomized Controlled Clinical Trial)

A Comparative Clinical Assessment of Adjunctive Hyaluronic Acid with 3D Printed Versus Milled CAD CAM Provisional Dental Restorations on active Periodontal status and Surface Roughness and biocompatibility (A Randomized Controlled clinical Trial).

This randomized clinical trial evaluates their effects regarding periodontal assessment, including

1. Clinical attachment loss (CAL)
2. Plaque Index (PI)
3. Gingival Index (GI)
4. Bleeding on probing (BOP)
5. using digital scanner then a profilometer to measure surface roughness
