摘要

慢性根尖周病变是人类牙齿中最常见的骨病理之一,通常首先通过x线平片(如全景或根尖周x线片)发现。x光平片广泛应用于牙科;然而,它们有技术本身固有的局限性,如解剖结构重叠和缺乏病变延伸的信息。因此,三维放射成像方法,如锥形束计算机断层扫描,对于准确评估根尖周围病变是有价值的。因此,本临床报告描述了一个病例,骨片特征导致初步诊断为上门牙慢性根尖周病变,然而,它是腭骨的缺陷。由腭骨缺损产生的放射率与上颌骨重叠,模拟根尖周围病变。此外,在同一病例中,我们在另一个区域发现了真正的慢性根尖周围病变,在根尖周围x线摄影中表现为微弱的放射透光,然而,在锥形束计算机断层扫描中评估时,它比预期的要大。

Palatal bone defect mimicking a chronic periapical lesion: a case report emphasizing the importance of the use of a three-dimensional radiographic examination
| Chronic periapical lesion is among the most usual bone pathology observed in human teeth, and it is often first detected by plain radiographs, such as panoramic or periapical radiography. Plain radiographs are widely used in dentistry; ho-wever, they have limitations inherent to the technique itself, such as anatomic structures overlapping and lack of information on the extension of the lesion. Therefore, three-dimensional radiographic methods, such as cone beam computed tomography are valuable to accurately assess periapical lesions. Thus, this clinical report describes a case in which the bone radiographic features led to a primary diagnosis of chronic periapical lesion in superior incisors, however, it was a defect in the palatal bone. The resulting radiolucency created by the palatal bone defect overlapped the maxillary bone, mimicking a periapical lesion. Additionally, in the same case, we demonstrate a true chronic periapical lesion in another area that presented as a subtle radiolucency in periapical radiography, however, it was larger than expected when evaluated in Cone Beam Computed Tomography.
