Abstract : In 1972, Simon et al. classified endo-perio lesions into five patterns based on etiology. However, just the concept was presented, without details directly leading to treatment strategies. Here, we report the case of a 36-year-old male with furcation lesion. Although the lesion was preoperatively diagnosed to have been caused by periodontal disease, it was considered that endodontic lesions were intricately involved based on the treatment process and results. The involved tooth was a double-rooted tooth. The electric pulp test result was positive, but the tooth had both vital and non-vital root canals which made diagnosis difficult before surgery. Additionally, the spread of periodontal lesions to the lateral branches of non-vital root canals complicated the situation. This case highlights that endo-perio lesions cannot always be accurately diagnosed before surgery, but reviewing the treatment results and continual evaluation of the etiology would help improve the success rate of treatment.
