Root resorption is an unwanted phenomenon occurring in a substantial population proportion these days. Hence, the current study was conducted to evaluate root resorption in endodontically treated teeth following fixed orthodontic treatment.
A total of 100 patients were enrolled. Only those patients were enrolled that were scheduled to undergo fixed orthodontic therapy. Pretreatment examination was done in all the patients, and their radiographs were obtained. Both orthopantomograms and peri-apical radiographs were taken. All the patients were recalled on follow-up, and radiographic examination was again carried out. Pretreatment radiographs and follow-up radiographs were compared. The incidence of root resorption was documented. The data were entered in an Excel sheet (Microsoft office version 2007) and analyzed using IBM SPSS software version 20.
Root resorption was present in 30 patients. Among these 30 patients, 20 were male, whereas 10 were female. In 19 patients, root resorption was present in the maxillary arch, whereas in 11 patients, it was seen in the mandibular arch. The most common tooth involved with root resorption was premolars, followed by anteriors and molars.
The risk of root resorption is higher in endodontically treated teeth under the influence of orthodontic forces.
牙根吸收是目前在相当一部分人群中出现的不良现象。因此,开展本研究以评估固定正畸治疗后根管治疗牙齿的牙根吸收情况。
共纳入100例患者。仅纳入那些计划接受固定正畸治疗的患者。对所有患者进行治疗前检查,并获取其X线片。拍摄曲面断层片和根尖片。所有患者在随访时复诊,并再次进行影像学检查。比较治疗前X线片和随访X线片。记录牙根吸收的发生率。数据录入Excel工作表(Microsoft office 2007版),并使用IBM SPSS软件20版进行分析。
30例患者出现牙根吸收。在这30例患者中,20例为男性,10例为女性。19例患者上颌弓出现牙根吸收,11例患者下颌弓出现牙根吸收。牙根吸收最常累及的牙齿是前磨牙,其次是前牙和磨牙。
在正畸力的影响下,根管治疗牙齿发生牙根吸收的风险更高。
