Different methods have been used for its treatment. This study was performed to clinically compare the changes observed in periodontal clinical indices between the two methods adopted in treatment of gingival recession: GRT and CTG.   Materials and Methods: In this experimental study, 24 cases of gingival recession were selected in 12 patients who had Miller’s class I and/or II gingival recession in their canines or premolars. Twelve areas were treated with CTG and 12 with GTR method. The studied indices including depth and width of recession, clinical attachment level, probing depth, and width of keratinized gingiva were measured before treatment and 1, 2, 3, and 6 months later. Data were analyzed using Wilcoxon, T-paired and ANOVA statistical tests.   Results: Both CTG and GTR methods led to significant decrease in depth of gingival recession (P=0.035), width of recession (p= 0.005), Improvement in clinical attachment level (P=0.05) and width of keratinized tissue (P=0.0001). But no significant difference was noticed between two groups regarding probing depth (P=0.3).   Conclusion: although both treatment methods considerably improved the treatment of gingival recession, CTG method was superior to GTR for increasing the width of keratinized tissue and decreasing the clinical attachment level.   تحلیل لثه, بافت همبند, ترمیم هدایت شده بافت Gingival recession,Guided tissue regeneration, Periodontal 130 135 http://jrds.ir/browse.php?a_code=A-10-775-2&slc_lang=fa&sid=1 SH Amini شیرین امینی 10031947532846009701 10031947532846009701 No Assistant professor Periodontics Dept, School of Dentistry, Azad Islamic University of Isfahan (Khorasgan), Isfahan, Iran Assistant professor Periodontics Dept, School of Dentistry, Azad Islamic University of Isfahan (Khorasgan), Isfahan, Iran H Golestaneh هدایت اله گلستانه 10031947532846009702 10031947532846009702 No Assistant professor Periodontics Dept, School of Dentistry, Azad Islamic University of Isfahan (Khorasgan), Isfahan, Iran Assistant professor Periodontics Dept, School of Dentistry, Azad Islamic University of Isfahan (Khorasgan), Isfahan, Iran SA Miremadi سید اصغر میر عمادی 10031947532846009703 10031947532846009703 No Professor, , Periodontics Dept, Tehran University of Medical Sciences Professor, , Periodontics Dept, Tehran University of Medical Sciences F Teymouri فراز تیموری faraz_teymouri@yahoo.com 10031947532846009704 10031947532846009704 Yes Postgraduate Student, Periodontics Dept, School of Dentistry, Azad Islamic University of Isfahan (Khorasgan), Isfahan, Iran Assistant Professor Oral and Maxillofacial Pathology Dept, School of Dentistry, Islamic Azad University, Isfahan (Khorasgan), Iran
