This study deals with coverage of multiple denuded roots. The current standard treatment
requires surgical correction and uses soft tissue taken from the roof of the mouth to enhance
results. The hypothesis of this trial is that a synthetic collagen matrix (called Mucograft)
can be used to replace soft tissue taken from the subject. If the collagen matrix will prove
to be equally as effective as the patient own tissue, it will be possible to avoid a more
extensive surgery and decrease pain and discomfort.
