“…[16][17][18][19][20]27 The syndromes associated with gingival fibromatosis include Zimmerman -Laband syndrome (GF, hypoplastic distal phalanges, hepatosplenomegaly, epilepsy, hypertrichosis, and mental retardation), Jones syndrome (GF and progressive neural deafness), Klippel -Trenaunay syndrome (GF, hemihypertrophy, Nevus flammeus, hemangioma, hypertlorism, and macrocephaly), Ramon syndrome (GF, hypertrichosis, mental retardation, epilepsy, rheumatoid arthritis, and diabetes mellitus), Rutherfurd syndrome (GF, unerupted teeth, corneal dystrophy, and mental retardation), Cross syndrome (GF, nanophthalmos, microcornea, and severe mental retardation), Murray -Puretic Drescher syndrome (Juvenile hyaline fibromas), Cornelia de Lange Syndrome, and Tuberous sclerosis. 4,[18][19][20][21]27 In the current study no patient presented with generalized gingival enlargement associated with any syndrome. It has recently been found that there are qualitative and quantitative differences in transforming growth factor beta -isoform (TGF-β) and receptor expression by fibroblasts in gingival overgrowth and this may contribute to the pathogenesis of the disease.…”
