title: Marginal adaptation and sealability of orthograde and retrograde amalgam obturation. An in vitro study.
abstract: 60 recently extracted anterior teeth were subjected to an endodontic protocol and obturated with either orthograde or retrograde amalgam (n = 30). Specimens were evaluated for microleakage and marginal adaptation using 2% methylene blue dye and scanning electron microscopy respectively. Chi-square analysis of data showed significantly better (p < 0.001) marginal adaptation and sealability in orthograde amalgam apical fillings.
