Comparison Between Two Coronally Positioned Flap With Connective Tissue

Comparison of Two Bilaminar Techniques for Root Covering of Miller´s Recessions Class I and II: A Blind, Randomized Controlled Clinical Trial

The aim of this study is to evaluate the effectiveness of total root coverage between two coronally positioned flap technique in Miller recession Class I and II, in patients attending at "Universidad El Bosque" dental school clinics.

This is a blind, randomized controlled clinical trial.

Inclusion Criteria:

• Class I and II Miller recessions showing a recession depth ≥ 2 mm.
• Recessions isolated and / or maximum continuous two teeth.
• Recessions in incisors, canines and premolars
• Patients 20 to 60 years old.

Exclusion Criteria:

• Systemic compromise, that contraindicates any periodontal surgical procedure.

  • Warfarin medication.
  • Uncontrolled diabetes mellitus with glycosylated hemoglobin ≥ 8
  • Chronic steroid therapy (dose of 7.5 mg/ day for more than 14 days)
  • HIV-AIDS infection with CD4 counts <200.
  • Immunosuppression.

• Recessions molars not be taken into account in the study.

• Patients who have used antibiotics one month prior to the surgical procedure.

• Pregnancy.

• Active smoker.

• Patients with a history of periodontal surgery at the recession area that has taken place in the last three months.

• Severe dental malposition, teeth rotation, versions teeth root coverage that contraindicates surgery.

• Non carious cervical lesions or caries where is not visible the cemento- enamel junction (CEJ).

• Active inflammation that contraindicates surgical procedure of the recession.

• Active Orthodontics
