本文回顾了不完全牙裂的徵象和症状,强调了咬(牙合)与下颌运动在不完全牙裂的病因及诊断中的作用。不完全牙裂的早期症状是患者咀嚼一些粗糙的,脆性或纤维性的食物时,往往有轻微、模糊的间歇性疼痛,在一段时期内虽经多次治疗而不适症状仍未减轻。裂缝扩大时患侧有突发的瞬时剧烈疼痛,所以患者常避免用患侧咀嚼。以上是非完全牙裂的早期症状。 This article reviews the signs and symptoms of incomplete tooth decay, highlighting the role of bite and mandibular movement in the etiology and diagnosis of incomplete tooth decay. Early symptoms of incomplete tooth fractures are those patients who chew some rough, brittle or fibrous foods often with mild, vague, intermittent pain that has not been alleviated despite repeated treatment over a period of time. When the crack is enlarged, there is sudden sudden severe pain in the affected side, so patients often avoid using the affected side to chew. The above is incomplete early tooth crack symptoms.
