Cracked tooth syndrome typically poses a diagnostic challenge for the dentist. Symptoms include tenderness to biting on certain foods, often poorly localized, and occasional thermal sensitivity. Knowing where to look for this entity, especially in the mandibular molar region, can be especially helpful. Treatment of the tooth depends on the degree of pulpal involvement and the extent of the crack. Cuspal coverage is required of all cracked posterior teeth that are retainable. Root canal therapy is included if symptoms persist or if pulpal pathosis exists at the outset. Cracks extending beyond the osseous crest indicate a poor prognosis. Armed with this knowledge, the dentist can overcome many cracked tooth dilemmas, resulting in satisfaction for both patient and practitioner alike.
牙隐裂综合征通常给牙医带来诊断挑战。症状包括咬某些食物时疼痛,疼痛部位往往不明确,偶尔有冷热敏感。了解在何处寻找这种情况,尤其是在下颌磨牙区,会特别有帮助。牙齿的治疗取决于牙髓受累程度和裂纹范围。所有可保留的后牙隐裂都需要进行牙尖覆盖。如果症状持续或一开始就存在牙髓病变,则需进行根管治疗。裂纹延伸至牙槽嵴以外提示预后不良。有了这些知识,牙医就能克服许多牙隐裂难题,使患者和医生都满意。
