OBJECTIVE
To investigate the clinical importance of incidental findings reported for small-volume cone beam computed tomography (CBCT) scans of impacted maxillary canine teeth.
STUDY DESIGN
Radiology reports of CBCT examinations performed as part of diagnosis and treatment planning for impacted or ectopically erupting maxillary canine teeth for 183 consecutive patients were assessed retrospectively. The scans were obtained with a small-volume unit (3 D Accuitomo 80) with a field of view that was either 40 × 40 or 60 × 60 mm. The findings were graded according to their clinical importance as low, intermediate, or high.
RESULTS
Three hundred and forty incidental findings were reported. One of the incidental findings was of high importance (0.3%), 97 were of intermediate importance (28.5%), and 242 were of low importance or anatomic variant (71.1%).
CONCLUSIONS
Incidental findings reported on small-dimension CBCT scans of impacted maxillary canine teeth rarely require immediate attention; nonetheless, 28.8% would require follow-up.
目的
探讨上颌阻生尖牙小视野锥形束计算机断层扫描（CBCT）中偶然发现的临床重要性。
研究设计
回顾性评估连续183例患者上颌阻生或异位萌出尖牙诊断和治疗计划中进行的CBCT检查的放射学报告。扫描使用小视野设备（3D Accuitomo 80），视野为40×40或60×60mm。根据临床重要性将发现分为低、中、高三个等级。
结果
共报告了340项偶然发现。其中1项具有高度重要性（0.3%），97项具有中度重要性（28.5%），242项具有低度重要性或为解剖变异（71.1%）。
结论
上颌阻生尖牙小视野CBCT扫描报告的偶然发现很少需要立即关注；尽管如此，28.8%的发现需要随访。
