【摘要】：正根管治療過(guò)程中,有時(shí)可能發(fā)現(xiàn)外源性物質(zhì)遺留在根管內(nèi)而影響治療。常見(jiàn)的醫(yī)源性因素,如根管銼、拔髓針、側(cè)壓針斷裂滯留等,對(duì)此類(lèi)因素的處理已有許多研究報(bào)道[1-2]。但在兒童患者,我們還可能碰到另一種較罕見(jiàn)的情況,即自傷性行為(Self-injurious behavior)造成的生活用品遺留在根管內(nèi)[3-4]。一般來(lái)說(shuō),外源性物質(zhì)滯留的位置越深,治療越困難,如果位于根尖孔外,則可能需要根尖手術(shù)[5]。本文報(bào)道1例較罕見(jiàn)的自傷性習(xí)慣導(dǎo)致的根管異物,應(yīng)用常規(guī)根管治療術(shù)成功予以清除,進(jìn)而得以實(shí)施完善的根管治療,保存了患牙。
[Abstract]:In the course of orthodontic root canal therapy, exogenous substances may sometimes be found in the root canal and affect the treatment. Common iatrogenic factors, such as root canal file, pullout needle, lateral compression needle and so on, have been reported in many studies [1-2]. In children, however, we may encounter another rare condition, namely, the existence of household goods caused by self-injury (Self-injurious behavior) in the root canals [3-4]. In general, the deeper the foreign substance stays, the more difficult it is to treat, and if located outside the apical foramen, it may require apical surgery [5]. This paper reports a rare case of root canal foreign body caused by self-injurious habit, which was successfully removed by conventional root canal therapy, and then the perfect root canal therapy was carried out and the affected teeth were preserved.
