Abstract:
INTRODUCTION:There are no long-term, prospective clinical studies assessing outcomes of endodontically treated cracked teeth with radicular extensions. The purpose of this prospective study was to examine the 2- to 4-year success and survival rates of endodontically treated, coronally restored, cracked teeth, specifically where the crack extends beyond the level of the canal orifice internally. METHODS:Seventy consecutive teeth requiring endodontic treatment with cracks extending to the level of the canal orifice and up to 5 mm beyond were included in the cohort. Treatment was performed by a single endodontist using current techniques, and cases were followed over time. Specific treatment and posttreatment protocols were used. A tooth was "survived" if it was present, asymptomatic, and functional. The category of "success" was given to a case if strict radiographic and clinical criteria were met. RESULTS:Fifty-nine teeth were eligible for survival analysis, and 53 teeth were available for success analysis. There was a 100% survival rate in the first 2 years and 96.6% survival up to the 4-year period; 90.6% were classified as "success" in the 2- to 4-year term. No significant differences (P < .05) were found for periodontal pocketing (up to 7 mm) at the site of the crack, marginal ridge involvement, crack depth, or pretreatment diagnoses. CONCLUSIONS:This study showed that the success and survival rates for cracked teeth with radicular extensions may be similar to endodontically treated teeth in general and may be higher than previously reported in cracked tooth studies. Treatment outcomes in cracked teeth with radicular extensions may be improved by using the following protocols: microscope-assisted intraorifice barriers placed apical to the extent of the crack, complete occlusal reduction, specific postoperative instructions, and expeditious placement of a full-coverage restoration.
