Periapical Surgery with BiodentineTM as a Retrograde Root-end Seal: A Clinical Case Series Study

Purpose: To evaluate the ability of BiodentineTM as a retrograde root-end filling in conjunction with a well-documented periapical surgery protocol in a clinical case series study. Material and Methods: Thirteen teeth in 13 patients referred for periapical surgery were included in the study. Teeth with obvious signs of root-fracture or apical-marginal communications were excluded from the study. The root-canals of the included teeth were prepared with an ultrasonic technique after an apicectomy of at least 3 mm of the apex. The treated canals were then filled with BiodentineTM as a retrograde root-end seal. Results: Twelve teeth were available for follow-up after a minimum of 12 months healing time. One patient was not available for the review. A radiological and clinical examination were performed at the follow-up visit and revealed a success of 92%. One tooth was stated as a failure (8%). The majority of the treated teeth were molars (n=8). Conclusion: BiodentineTM seems to be a suitable retrograde root-end filling material when used with a modern periapical surgery technique. However larger prospective studies are needed to compare the material to other well-documented materials. Alterations of the material to increase the usability and evaluation opportunity would be desirable.
