Recession Coverage Case Series Presented in EuroPerio 2018.
Background
The data on the potential benefits of Hyaluronic acid (HA) for recession coverage surgery is still limited.
Aim
To evaluate the potential effects of HA on the early wound healing and clinical outcomes following recession coverage surgery.
Materials and Methods
Fifteen female patients (mean age 32.2 years) exhibiting a total of 25 single or multiple Miller Class I, II and III gingival recessions were
consecutively treated by means of the modified coronally advanced tunnel (MCAT) or the laterally moved tunnel (LMT) in conjunction with the application of hyaluronic acid (Hyadent, Regedent AG, Zürich, Switzerland) on the root surfaces and subsequent placement and a palatal subepithelial connective tissue graft (SCTG). Intraoral photos were taken at baseline, 2 and 24 weeks postoperatively. Recession depth (RD), recession coverage (RC), probing depth (PD), width of the attached gingiva (AG) were measured at baseline and at 24 weeks following surgery.
Results
The material comprised 8 Miller Class I, 5 Miller Class II and 13 Miller Class III recessions. Four defects were located in the upper jaw, while the rest of 25 recession were in the lower jaw. Healing was uneventful in all cases. At six months, statistically significant improvements in RD and RC were found in all defects. RD improved from 3.75mm ± 1.35 mm at baseline to 0.38mm ± 0.68 mm (p<0.0001) at six months while RC amounted to 90.03% ± 17.1.
Conclusion
The present findings suggest that the use of HA as adjunctive to recession coverage surgery is safe and may positively influence the clinical outcomes.
