A new technique for nonsurgical retreatment of teeth with amalgam root end fillings: case series.

摘要

INTRODUCTION: The objective of this article was to show an alternative clinical approach to retreating teeth having had prior combined nonsurgical and surgical endodontic treatment with retrograde amalgam fillings. Nonsurgical retreatment performed alone has historically presented numerous challenges for the clinician and an uncertain outcome for the patient. Surgical retreatment has the potential disadvantages of additional root shortening, bone loss, and scarring. METHODS: Four cases are presented with recalls up to 5.5 years. RESULTS: The procedure was shown to be predictable and successful in this series. Root length was preserved, and surgery was avoided. CONCLUSIONS: Nonsurgical amalgam removal from the root end may provide a desirable alternative to the more common and complicated option of combined nonsurgical and surgical endodontic retreatment.
