Brief summary
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.
Detailed description
This is a blind, randomized controlled clinical trial.
Interventions
PROCEDUREcoronally partial thickness flap plus connective tissue
The design of the flap will be performed according to the technique described by de Sanctis and Zucchelli 2007.
PROCEDUREcoronally mucosal thickness flap
The design of the flap will be performed according to the technique described by Greenwell H, Vance G, Munninger B and Johnston H.

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
