Certain patients may be considered as being at "risk" with respect to the possibility of development of significant diseases of either a local or a systemic nature as a direct result of the presence of oral infection. The problems relating to the development of bacteremia subsequent to surgery in the patient with cardiovascular disease are well appreciated. Thought should be given to the possibilities of such developments in relation to the presence of periapical pathosis. It is demonstrated that a definitive evaluation of the status of the nonvital tooth cannot be made by the presently accepted methods of clinical and radiographic examination.
某些患者可能因口腔感染直接导致出现局部或全身性重大疾病而被视为处于“风险”之中。心血管疾病患者术后发生菌血症的相关问题已广为人知。对于根尖周病变的存在，应考虑到此类情况发展的可能性。结果表明，目前公认的临床和影像学检查方法无法对无活力牙的状况进行明确评估。
