Aim. To report a case with an unusual drainage route of periapical inflammation exiting through the gingival sulcus of an adjacent vital tooth and review probable factors determining the diversity of the discharge routes of periapical inflammation. Summary. An 18-year-old male patient presented with periodontal abscess of tooth 46, which was found to be caused by a periapical cyst with an acute abscess of tooth 45. During endodontic surgery, a rarely reported drainage route for periapical inflammation via the gingival sulcus of an adjacent vital tooth was observed for the first time. Complete periodontal healing of the deep pocket of tooth 46 and hiding of the periapical cyst of tooth 45 followed after root canal treatment and periapical surgery with Bio-Oss Collagen implantation on tooth 45. The drainage routes of periapical inflammation are multivariate and the diversity of drainage pathways of periapical inflammation is mainly related to factors such as gravity, barriers against inflammation, and the causative tooth itself.
目的。报告一例根尖周炎通过相邻健康牙齿的牙龈沟排出的异常引流途径的病例，并探讨决定根尖周炎引流途径多样性的可能因素。摘要。一名18岁男性患者出现46号牙的牙周脓肿，发现是由45号牙的根尖囊肿伴急性脓肿引起的。在牙髓手术过程中，首次观察到一种罕见的根尖周炎通过相邻健康牙齿牙龈沟的引流途径。45号牙根管治疗及根尖手术后植入Bio-Oss Collagen，46号牙深牙周袋完全愈合，45号牙根尖囊肿消失。根尖周炎的引流途径是多因素的，根尖周炎引流途径的多样性主要与重力、炎症屏障及患牙本身等因素有关。
