title: A Preliminary Clinical Comparison of the Use of Fascia Lata Allograft and Autogenous Connective Tissue Graft in Multiple Gingival Recession Coverage Based on the Tunnel Technique.
abstract: BACKGROUND
  The most effective method for treating gingival recessions (GR) is with an autogenous connective tissue graft (CTG) via flap surgery. Often, however, the amount of CTG that can be grafted is insufficient to cover all of a patient's gingival recessions at one time.
  
  
  OBJECTIVE
  The objective of this study was to provide a 6-month comparative assessment of the results of covering multiple Miller Class I and II gingival recessions with a Fascia Lata Allograft (FL) and a CTG harvested from palatal mucosa.
  
  
  METHODS
  The study comprised a total of 30 people who underwent multiple gingival recession (GR) procedures using a modified, coronally advanced tunnel technique (MCAT). The patients were divided into two groups of 15 according to the type of materials used for gingival augmentation purposes: FL for the test group and CTG for the control group. A clinical assessment was made at baseline, as well as 3 and 6 months following surgery. The following factors were assessed: recession depth, recession width, probing depth, clinical attachment level, height of keratinized tissue (HKT), distance between the cemento-enamel junction and the muco-gingival junction (CEJ-MGJ), API, SBI. The following values were calculated: average root coverage (ARC), complete root coverage (CRC).
  
  
  RESULTS
  No statistically significant differences were observed between the groups in terms of clinical parameters assessed after 6 months, apart from CRC, which was 94.87 ± 0.14 mm in the control group and 94.24 ± 0.20 mm in the study group (p = 0.034). The average HKT in the control group after 6 months amounted to 2.86 ± 1.60 mm, and in the test group to 3.09 ± 0.95 mm, which translates into an increase in comparison to the baseline values of 0.73 mm (p < 0.001) and 0.48 mm (p = 0.017), respectively.
  
  
  CONCLUSIONS
  FL Allografts may serve as an alternative to autogenous CTG in multiple gingival recession coverage procedures based on the tunnel technique.
