S-6 Decompression of Large Apical Lesions
CE Hours: 1.0
Description: Nonsurgical endodontic therapy is highly successful in the treatment of apical periodontitis; however, Nair states that true apical cysts likely will not heal without surgical intervention. Apical surgery with root-end resection and root-end filling of teeth with unhealed apical periodontitis is also highly successful. Often these lesions can be very large and encompass adjacent teeth with vital pulps. Complete enucleation of a large apical lesion can potentially lead to devitalization of adjacent teeth with vital pulps. Decompression of these large apical lesions, following nonsurgical endodontic treatment, can lead to a reduction in the size of the lesion, and in some cases lead to complete healing. However, most cases will need surgical intervention. The advantage of decompression is that, even if surgery is required to bring about complete healing, the lesion is reduced in size to the extent that adjacent teeth with vital pulps will not be subjected to devitalization from the surgical procedure. Cases demonstrating different approaches and techniques for decompression will be presented.
