Abstract
Background
The aim of this study was to evaluate clinical one-dimensional changes such as root surface coverage, decrease seen in the amount of gingival recession and keratinised gingival width (KGW) obtained throughout a 6-month follow-up period following the treatment of Cairo class II gingival recession with free gingival graft (FGG) and gingival unit graft (GUG). Three-dimensional changes in gingival volume and thickness were also compared digitally using an indirect method.
Methods
A total of 20 patients with localised Cairo class II gingival recession were randomly separated into two groups; 10 patients were treated with FGG and 10 patients treated with GUG. Preoperatively and at 6 months postoperatively, the initial position of the gingiva and KGW were recorded for all the patients and plaster models were formed from the obtained impressions with the traditional method. The plaster models were transferred to a digital environment by scanning with a model scanner. Using a software program, changes in gingival papillary height and gingival volume and thickness were compared between the groups and according to the baseline values from The Standard Tessellation Language (STL) files obtained.
Results
Compared to the baseline values, a significant increase was determined in the KGW, and a significant decrease in pocket depth, clinical attachment level, and gingiva recession depth in all the groups (p<0.05). No statistically significant difference was determined between the groups in respect of the changes in mean gingiva thickness, gingiva volume, and mean vertical papillary height (p>0.05).
Conclusion
The study results showed that GUG treatment for Cairo class II localised gingival recession is an effective method in respect of increasing gingiva volume and thickness, increasing KGW, coverage of the root surface, and forming tissue contours that allow the patient to easily maintain oral hygiene. However, there was not seen to be any adventage of GUG and FGG over each other.
