Mariotti (1999) characterized gingival diseases with presence of 1) signs and symptoms that are confined to gingiva 2) presence of dental plaque to initiate and exacerbate severity of lesions 3) clinical signs of inflammation (enlarged gingival contours due to edema or fibrosis, colour transition to a red and bluish-red hue, elevated sulcular temperature, bleeding upon stimulation, increased gingival exudates 4) clinical signs and symptoms associated with stable attachment levels on a periodontium with no loss of attachment or on a stable but reduced periodontium 5) reversibility of disease by removing the etiology 6) possible role as a precursor to attachment loss, around teeth.
Objective: The PRE-Facto fellowship aims to develop a new regenerative approach which potentially will promote the revival of the periodontium, while a successful outcome may lead also to the prevention of the disease when intervened early.
