RecruitingProcedureComparison of Two Methods of Covering a Single Lower Front Tooth With Receded GumsThe primary objective of this randomized clinical trial is to compare the mean root coverage achieved with Coronally Advanced Flap (CAF) + Connective Tissue Graft (CTG) (control) to Gingival Pedicle Split Thickness flap (GPST) + CTG (test) for the treatment of isolated gingival recession defects in mandibular incisors. The secondary objectives are to compare the percentage of complete root coverage and keratinized tissue gain between the two techniques.
