确定乳牙的外根吸收情况对制定乳牙治疗计划具有重要意义。虽然数字x线摄影在诊断恒牙列外根吸收方面的准确性已经建立，但它不能完全推广到由后续恒牙叠加的主根。有趣的是，目前还没有研究对乳牙进行评估。因此，本研究为首次开展。这是一项单盲前瞻性临床诊断研究，对45个上颌/下颌初级磨牙（6 - 8岁患者）的167根进行了501次观察（由3名观察员观察），这些患者需要拔牙，并且确实有后续的恒牙。拔牙前使用PSP传感器拍摄数字平行根尖周围x线片。两名儿科牙医打印并检查了x光片。拔牙后，吸收程度由第三和第四个不知道放射学估计的观察者直接测量两次。计算射线照相误差和绝对误差（mm）。对各参数进行统计分析。根被真正吸收的占56.3%（平均= 5.01±2.10 mm）。第一/第二观察者分别不能识别19.6%和38.3%的根。女孩和男孩的平均误差分别为- 0.77±2.31和0.14±2.19 mm （P=0.043， t检验）。侧面、下颌、牙型、牙根类型对误差无显著影响（P < 0.05）。平均绝对误差为1.79±1.47 mm（显著高于零，P < 0.0005）。无评价因素影响（P < 0.01）。实际病变大小与误差相关（Pearson R = 0.682, P < 0.0005），但与绝对误差无关（P=0.464）。虽然许多乳根可能会被遗漏，但数字x线摄影仍然可以提供相当好的诊断和测量外根吸收的准确性，绝对误差约为1.8 mm。观察者可能高估女孩和实际病变小于3mm的病例的吸收大小。病变的大小可以影响误差的方向（缩短/伸长），但不影响其无方向的大小。
Identifying the external root resorption plays an important role in treatment planning for deciduous teeth. Although proper accuracy of digital radiography in the diagnosis of external root resorption has been established in permanent dentition, it cannot be at all generalized to the primary root being superimposed by the succeeding permanent teeth. Interestingly, no study has assessed this in primary teeth yet. Thus, this study was undertaken for the first time. This was a single-blind prospective clinical diagnostic study performed on 501 observations (observed by 3 observers) pertaining to 167 roots of 45 maxillary/mandibular primary molars (in 6–8-year-old patients) which were indicated for extraction and did have succeeding permanent teeth. Digital parallel periapical radiographs were taken before dental extraction using a PSP sensor. Radiographs were printed and examined by two pediatric dentists. After the extraction, the extent of resorption was directly measured, twice, by third and fourth observers blinded to radiographic estimates. Radiographic errors and absolute errors (mm) were calculated. Various parameters were analyzed statistically. Of the roots, 56.3% were really resorbed with (mean = 5.01 ± 2.10 mm). First/second observers failed to identify 19.6% and 38.3% of roots, respectively. Average errors were −0.77 ± 2.31 and 0.14 ± 2.19 mm in girls and boys, respectively (P=0.043, t-test). The factors “side, jaw, tooth type, and root type” did not affect errors (P > 0.05). Average absolute errors were 1.79 ± 1.47 mm (significantly above zero, P < 0.0005). No evaluated factor affected it (P > 0.1). Actual lesion sizes correlated with errors (Pearson R = 0.682, P < 0.0005) but not with absolute errors (P=0.464). Although many deciduous roots might be missed, digital radiography might still provide rather a good accuracy in diagnosis and measurement of external root resorption up to about 1.8 mm absolute error. Observers might overestimate resorption sizes in girls and in cases with actual lesions smaller than 3 mm. Size of the lesion can influence the direction of error (shortening/elongation), but not its directionless magnitude.
