Statement of Problem: Treatment of gingival recession defect and covering denuded root surfaces is one of the goals in periodontal therapy and several surgical techniques have been suggested in this field.
Purpose: The aim of this study was to perform a comparison on coronaliy repositioned flap procedure with and without the use of ethylenediaminoteraacetic acid (EDTA. 24%, pH=7) in the treatment of recession defects.
Material and Methods: In this randomized clinical trial study, 16 patients, aged 17-60 years, with a total of 27 miller class 1 isolated buccal gingival recession type defects of at least 2mm depth, and based on special criteria were investigated. After initial therapy, surgical recession coverage was performed as coronaliy advanced flap technique and EDTA gel conditioning (test) or coronaliy advanced flap alone (control). Clinical examination including assessments of oral hygiene, recession depth (RD), recession width (RW), width of keratinized tissue (KT), probing depth (PD) and probing attachment level (PAL)were performed before and 1, 2, 3 months after surgical treatment.
Results: The mean of initial RD, RW, KT, PT and PAL in the test group was 2.73, 3.17, 3.13, 1.1 and 3.83mm respectively and in the control group was 2.56, 3.03, 3.67, 1.25, 3.92mm respectively. The mean of these parameters 3 months after treatment in the test group were changed to 0.46, 1.97, 2.65, 0.67, 1.1 mm, corresponding figures for control teeth were 0.85, 2.98, 2.75, 1, 1.94, respectively. At 3 months after treatment the mean root coverage amounted to 83% (test) and 67% (control) which was a statistically significant difference (P=0.0067). Although a significant clinical difference was observed regarinding root coverage level, all other clinical variables were not statistically different, with the exception of probing attachment level (P=0.005).
Conclusion: It was suggested that EDTA gel (24%, PLT=7) for 3 minutes as root conditioner and the coronaliy advanced flap procedure can be used as a predictable and successful method in the treatment of miller class I buccal gingiva! recession type defects.
