今天在外滩那边打疫苗的时候碰到这次6月一起面上的同学,聊天中得知他是去徐汇牙防所(靠近复旦大学医学院这边)拍的片子,全景片么啥问题,但是2张BITEWING和我拍的不同,我在同济大学附属口腔医院拍的中文名叫颌翼片或咬翼片,但是他拍的是咬颌片。差别就是颌翼片是左右2张,而咬颌片是上下2张。
根据WIKI的解释
Bitewing view
The bitewing view is taken to visualize the crowns of the posterior teeth and the height of the alveolar bone in relation to the cementoenamel junctions, which are the demarcation lines on the teeth which separate tooth crown from tooth root. When there is extensive bone loss, the films may be situated with their longer dimension in the vertical axis so as to better visualize their levels in relation to the teeth. Because bitewing views are taken from a more or less perpendicular angle to the buccal surface of the teeth, they more accurately exhibit the bone levels than do periapical views. Bitewings of the anterior teeth are not taken.
The name bitewing refers to a little tab of paper or plastic situated in the center of the X-ray film, which when bitten on, allows the film to hover so that it captures an even amount of maxillary and mandibular information.
具体不做翻译的,简单的说BITEWING是用来查看后部牙齿牙冠和牙根的关系的,拍摄角度应该是垂直于牙齿的,所以正确的应该是左右2张得颌翼片,如果是上下2张得片子,是无法看出牙根的,而且拍摄角度一定是平行牙齿的。
给还没有做检查的同学提醒一下,如果说中文名字,要用颌翼片或者咬翼片,一定不是咬颌片。
最后上一张网上的BITEWING片子图给大家参照一下。
