OBJECTIVE
The purpose of this study was to evaluate the dentomaxillofacial imaging features of one family affected by the gingival fibromatosis (GF) and dental abnormalities (DA) syndrome.
METHODS
Conventional radiographs (periapical and panoramic) and cone beam CT (CBCT) were performed in nine members of this family: four were affected by the syndrome and five were not.
RESULTS
The four affected members demonstrated mild generalized GF in association with DA, including hypoplastic amelogenesis imperfecta, intrapulpal calcifications, delay on tooth eruption and pericoronal radiolucencies in unerupted teeth. None of these oral changes were identified in the five unaffected members. All nine members presented alterations in the paranasal sinuses and mucosal thickening of the maxillary sinus was the most common finding.
CONCLUSION
Family members not affected by the syndrome showed similar alterations in the paranasal sinuses and CBCT was useful to characterize the dentomaxillofacial features of this new syndrome associating GF and DA.
目的
本研究旨在评估一个受牙龈纤维瘤病（GF）和牙齿异常（DA）综合征影响的家族的牙颌面影像学特征。
方法
对该家族的 9 名成员进行了常规 X 线（根尖和全景）和锥形束 CT（CBCT）检查：其中 4 名受该综合征影响，5 名不受影响。
结果
受影响的 4 名成员表现出轻微的全身性 GF 伴 DA，包括釉质发育不全、牙髓内钙化、牙齿萌出延迟和未萌出牙的冠周透亮区。在 5 名未受影响的成员中未发现这些口腔变化。9 名成员均出现副鼻窦改变，上颌窦黏膜增厚是最常见的表现。
结论
不受综合征影响的家族成员的副鼻窦也存在类似的改变，CBCT 可用于描述这种新的综合征，其特征是 GF 和 DA 并存。
