Factors in the etiology of the cracked or fractured tooth can be generally divided into three categories: tooth strength, magnitude of applied force, and control of applied force. Dental caries, restorations and endodontic procedures appear to play a major part in the etiology of most cracked or fractured teeth though sound teeth frequently are cracked or fractured. Tentative evidence indicates that females, who can apply less force, may crack more teeth than do males. Control of occlusal forces applied may be an overlooked factor. Drugs affecting proprioception and other sensory receptors modulating force and reflex should be evaluated as possible contributors to the etiology of cracked or fractured teeth.
牙齿强度、施加力的大小以及对施加力的控制。龋齿、修复体和牙髓治疗在大多数牙齿出现裂纹或折断的病因中似乎起着主要作用，尽管健康的牙齿也经常出现裂纹或折断。初步证据表明，施加力较小的女性可能比男性更容易出现牙齿裂纹。对施加的咬合力的控制可能是一个被忽视的因素。影响本体感觉和其他调节力及反射的感觉受体的药物，应被评估为牙齿出现裂纹或折断病因的可能因素。
