NCT03462368

Brief Summary

The aim of this study was to evaluate the effect of two different treatment agents used in conjunction with subepithelial connective graft technique on root coverage outcomes in multiple recession defects. Half of patients will receive root treatment with antimicrobial photodynamic therapy and the other half will receive photobiomodulation therapy by laser on surgery site.

Control

ACTIVE COMPARATOR

Root surface treatment by scaling and root planing

Procedure: Control

antimicrobial photodynamic therapy

EXPERIMENTAL

Root surface treatment by antimicrobial photodynamic therapy

Procedure: antimicrobial photodynamic therapy

Photobiomodulation

ACTIVE COMPARATOR

Treatment of the whole surgical site with laser

Procedure: Photobiomodulation

Interventions

ControlPROCEDURE

In the procedure of subepithelial connective tissue graft, exposed dental roots will be treated by scaling and root planing only.

Also known as: Scaling and root planing only
Control

In the procedure of subepithelial connective tissue graft, exposed dental roots will be treated by antimicrobial photodynamic therapy with toluidine blue O (10mg/ml)

antimicrobial photodynamic therapy

After the procedure of subepithelial connective tissue graft the whole surgical site will receive red laser application.

Also known as: Low level laser therapy
Photobiomodulation
