Abstract
With our study we wanted to compare the diagnostic accuracy of conventional radiography (orthopanoramic and intraoral radiography) and Cone Beam CT (CBCT) for the diagnosis of periapical lesions on the posterior elements of the upper maxilla endodontically treated.The images were analyzed by a radiologist and an endodontist whose interpretation of radiological examinations is unique. Were examined 34 molars (23 first molars and 13 second molars) with a total of 102 roots. The CBCT detected a significantly higher number of lesions (43%, p <0.001) compared to conventional radiography. Our results demonstrate that the CBCT can be inserted into the diagnostic routine for the evaluation of all pre-prosthetic posterior elements of the upper jaw endodontically treated in addition to the diagnostic techniques 2D, especially when in the treatment plan is provided the realization of an abutment. The CBCT, which has reduction of cost and absorption of radiation with respect to the conventional CT, is also very useful even when there is a need to perform a surgical treatment-endodontic (apicectomy) of a lesion diagnosed with 2D techniques.
摘要
通过我们的研究，我们希望比较传统放射成像（全景片和口内片）和锥形束CT（CBCT）对上颌后牙区经牙髓治疗根尖周病变的诊断准确性。图像由一位放射科医生和一位牙髓病医生进行分析，他们对放射学检查的解读独具特色。共检查了34颗磨牙（23颗第一磨牙和13颗第二磨牙），共计102个牙根。与传统放射成像相比，CBCT检测到的病变数量显著更多（43%，p<0.001）。我们的结果表明，除了二维诊断技术外，CBCT可纳入对上颌后牙区所有经牙髓治疗的修复前牙体的评估诊断流程，特别是在治疗计划中需要制作基牙时。与传统CT相比，CBCT成本更低且辐射吸收更少，即使需要对二维技术诊断出的病变进行牙髓外科治疗（根尖切除术）时，它也非常有用。
