Management of Class I and Class II Amalgam Restorations with Localized Defects: Five-Year Results

摘要: Replacement of dental restorations has been the traditional treatment for defective restorations. This five-year prospective clinical trial evaluated amalgam with localized defects that were treated by means repair or refurbishing. Fifty-two patients (50% female and 50% male, mean age id="x33" d="M285 378v-2q65 -13 102 -54.5t37 -97.5q0 -57 -30.5 -104.5t-74 -75t-85.5 -42t-72 -14.5q-31 -59.5 11t-40.5 23q-19 18 -16 36q1 16 23 33q13 10 24 0q58 -51 124 -51q55 88 40t33 112q0 64 96.5t-88 32.5q-29 -64 -11l-6 29q77 25 118 57.5t41 84.5 q0 -26.5 69.5t-68.5 24.5q-67 -120 -79l-20 20l43 63q51 56 127 56h1q66 107 -37t41 -95q0 -42 -31 -71q-22 -23 -68 -54z" years, range 18–80) 160 class I II included. The study focused on application two minimally invasive treatments restoration compared these no total replacement as negative positive controls, respectively. Restorations assessed calibrated examiners according to modified U.S. Public Health Service criteria, including marginal adaptation, anatomic form, secondary caries, roughness.
