Marginal adaptation and sealability of orthograde and retrograde amalgam obturation. An in vitro study.
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.
