重度牙周炎患牙的保存治疗

Severe periodontitis-involved teeth, especially those considered as “prognosis hopeless”, are a common and important problem that plagues dentists. Clinicians should not make abrupt extraction decisions but rather carefully perform clinical examination, fully communicate with the patient, explore the correct etiological factors, and analyze the favorable and unfavorable factors according to the specific conditions of the patient. Patient’s willingness, compliance, and financial ability should also be considered. This review begins with three typical cases, including simple severe periodontitis-affected teeth, primary periodontal lesion with secondary endodontic involvement teeth, and teeth with “true combined periodontal-endodontic lesion.” The decision-making process of tooth extraction or retention in patients with severe periodontitis was also discussed to serve as future reference.
