INTRODUCTION: The correction of the gingival recession is of esthetical and
functional significance, but the tissue regeneration can only be confirmed by a
histological examination. AIM: This study aims to make a comparison between the
free gingival graft and the autograft. MATERIAL AND METHODS: This study included
24 patients with single and multiple gingival recessions. Twelve patients were
treated with a free gingival graft and the other twelve with a micrograft. Six
months after the surgical procedure, a micro-punch biopsy of the transplantation
area was performed. The tissue was histologically evaluated, graded in 4
categories: immature, mature, fragmented and edematous collagen tissue. The
elastic fibres were also examined and graded in three categories: with a normal
structure, fragmented rare and fragmented multiplied. RESULTS: Regarding the type
of collagen tissue that was present, there was a significant difference between
the two groups of patients, with a larger number of patients treated with a
micrograft showing a presence of mature tissue, compared to the patients treated
with a free gingival graft. A larger number of patients in both of the groups
displayed elastic fibres with a rare fragmented structure; 33.3% of the patients
showed a normal structure; 50% demonstrated a normal structure. CONCLUSION: The
patients treated with a free gingival graft showed a larger presence of
fragmented collagen tissue and fragmented elastic fibres, whereas a mature tissue
was predominantly present in the surgical area where a Geistlich Mucograft was
placed.
