Abstract
A case of bilateral impaction of the lower second molars is presented. A 15-year-old boy with an ill feeling at the right lower first molar was referred to us. X-ray examination revealed bilateral impaction of the lower second molars and the presence of bilateral teeth that seemed to be the unerupted third molars distal to the impacted second molars. Furthermore, a radiolucency approximately 3 X 3 mm in size was detected in the mesioapical region of the right lower first molar. These impactions were managed under local anesthesia by extraction of the right lower first molar and fenestration of the right lower second molar. After approximately 4.5 months, the right lower third molar was extracted. It was further followed approximately 1 month later by extraction of the left lower third molar and ipsilateral fenestration of the lower second molar. As a result, the right lower second molar erupted but it was considerably inclined in a mesial direction. The left lower second molar erupted normally almost up to the occlusal plane. In the absence of systemic abnormality, facial trauma, and maldevelopment of the jaw, impaction seemed to have been closely associated with some unknown local factor.
本文报告一例双侧第二磨牙嵌塞。一个15岁的男孩,右下第一磨牙感觉不舒服。x线检查显示双侧嵌塞的下第二磨牙和双侧牙齿的存在,似乎是未爆发的第三磨牙远端阻生第二磨牙。此外,在右下第一磨牙的中尖区检测到约3 X 3mm大小的放射光。这些嵌塞在局部麻醉下通过拔除右下第一磨牙和开窗右下第二磨牙来处理。大约4.5个月后,拔除右下第三磨牙。大约1个月后进一步拔除左下第三磨牙和同侧下第二磨牙开窗。结果,右下第二磨牙爆发,但它在中间方向明显倾斜。左下第二磨牙正常出牙,几乎达到咬合平面。在没有全身异常、面部创伤和颌骨发育不良的情况下,嵌塞似乎与一些未知的局部因素密切相关。
