Management of failed periodontal surgical intervention for a furcal lesion with a nonsurgical endodontic approach

• Asgary S

Abstract

As long as the prognosis of teeth remains a matter of concern, the endodontic-periodontal relationship will be considered a challenge for the clinician. Many etiologic factors, including bacteria, fungi, and viruses, plus other contributing factors, such as trauma, root resorptions/perforations, and dental malformations, play a role in the co-occurrence of endodontic and periodontal lesions. Whatever the cause, a correct diagnosis on which to base the treatment plan is the key to successful maintenance of the tooth. This article reports the successful endodontic management of a furcation lesion in a mandibular molar that was nonresponsive to a previous periodontal surgical graft. The case had presented a diagnostic challenge for the clinicians, and this article reviews the key points that can lead to a correct diagnosis and treatment planning.

  Figure 1 (a) Pretreatment radiography of tooth #46. Note the radiolucency in the furcation area and around the mesiobuccal root. Further, note the previous alloplastic graft in the furcation area, to which the lesion was nonresponsive; (b) Post-treatment radiography. The canals have been cleaned and obturated; (c) One-year follow-up radiography; (d) Two-year follow-up radiography. The tooth was restored one week after endodontic retreatment. The lesion in the furcation area and around the root healed completely. The alloplastic graft was not resorbed.
