磨牙紧邻咽部,采用口内摄片法按照,易引起患者恶心,呕吐等一系列反应.尤其在投照下颌磨牙时,因牙片刺激,致唾液分泌增多,大量的唾液易浸透包片黑纸与胶片发生粘连,投照后若不及时冲洗,胶片上的黑纸就难以除掉,冲洗出来的照片不能使用,导致摄片的失败.特别是没有牙科X线机的基层医疗单位,多采用普通X线机投照,但只能显示一侧上颌或下颌的磨牙.针对上述情况,我们把下颌骨侧位投照法加以改进,通过300例患者应用改进的上、下颌磨牙一次投照法,成功率达100%,取得了比较满意的效果,现将投照方法介绍如下.
Molar close to the pharynx, the use of oral radiography in accordance with the law, easily lead to nausea, vomiting and a series of reactions, especially in the mandibular molar project, due to tooth stimulation, resulting in increased salivation, saliva easy to digest a large number of black paper And film adhesions, if not after the projection flushing, the black film on the film is difficult to get rid of, out of the photos can not be used, leading to the failure of the film .Especially there is no dental X-ray machine primary medical units, the use of more Ordinary X-ray machine projection, but can only show one side of the maxillary or mandibular molars in view of the above situation, we put the mandibular lateral projection method to be improved by 300 patients with improved upper and lower jaw molar once cast method , The success rate of 100%, and achieved satisfactory results, the projection methods are introduced below.
