A Histologic Study of Gingival Tissue Response to Amalgam, Silicate and Resin Restorations

Creep, corrosion and marginal fracture of dental amalgams

“…Phosphorous and calcium have been identified in the corrosion products both inside and outside amalgam restorations (Wing, 1974;Holland & Asgar, 1974). When traced further, such histopathological reactions as inflammation in the adjacent soft tissues, vascular changes, reduction of the odontoblastic layers, and accumulation of leucocytes can be related to the corrosion ofthe tin-mercury phase (Hals & Narnaes, 1971;Hals et al, 1974;Zander, 1957;App, 1961;Sotres, Huysen & Gilmore, 1969;Trivedi & Talim, 1973;Brannstrom, 1963;Swerdlow & Stanley, 1962).…”

Periodontal Tissue Response to Coverage of Root Cavities Restored With Resin Materials: A Histomorphometric Study in Dogs

“…Dental restorative materials have been extensively studied, especially with regard to adhesion, 4 polishing and final finishing, 5,6 biocompatibility, 7‐12 and esthetics 13 . Subgingival restorations may cause alterations because of direct trauma to the periodontal tissues 14 or may facilitate the accumulation of subgingival plaque with consequent inflammatory alterations and/or recession of adjacent gingival tissue 15,16 .…”

Relationship between alignment conditions of teeth in anterior segments and dental health

“…It has been demonstrated previously (Waerhaug & Zander 1957, Zander 1957, Sotres et al 1969, Larato 1971, Weitman & Eames 1975 and confirmed recently (Silness & R0ynstrand 1984) that silicate, resin, and composite restorations tend to accumulate more plaque and cause increased gingival inflammation as compared to tooth surfaces without fillings. In the NONAS groups, the distribution of proximal restorations was not homogeneous.…”
