Abstract：
OBJECTIVE: To evaluate the cystic changes in the radiographically normal dental follicle associated with impacted mandibular third molar.
METHODS: This study was conducted on 80 patients. Samples were selected using a convenient sampling technique from the patients who had impacted mandibular third molars in Pell and Gregory\'s positions B and C, with follicular space less than 2.5 mm in diameter. After surgical removal of an impacted tooth, the dental follicle was sent for histopathologic evaluation.
RESULTS: Pathologic alterations were found in 19% of cases out of 80 samples. Odontogenic keratocystic and dentigerous cystic changes were found in 7% of cases. A statistically significant cystic alteration was found in female patients and distoangular impacted teeth.
CONCLUSIONS: This study shows a significant cystic alteration in the radiologically normal dental follicles. Clinical and radiographic features alone may not be a reliable indicator of the absence of pathology. Early intervention of impacted teeth will help to reduce morbidity due to the development of pathology.
CONCLUSIONS: This study will help educate patients on the risks of retaining impacted teeth, based on scientific facts, in order to minimize the risks and to assess the correlation of pathologic alterations with the depth of impaction and angular position of the impacted tooth.

摘要：
目的：评估与下颌阻生第三磨牙相关的影像学正常牙囊囊性改变。
方法：本研究对80例患者进行。使用方便的采样技术从Pell和Gregory位置B和C处影响下颌第三磨牙的患者中选择样本，直径小于2.5毫米的卵泡空间。手术切除受影响的牙齿后，我们将牙囊送去进行组织病理学评估.
结果：在80个样本中，有19%的病例出现病理改变。在7％的病例中发现了牙源性角化囊性和牙性囊性改变。在女性患者和四角阻生牙齿中发现了统计学上显着的囊性改变。
结论：本研究显示放射学正常牙囊的显著囊性改变。单独的临床和影像学特征可能不是病理缺失的可靠指标。由于病理的发展，早期干预患牙将有助于降低发病率。
结论：这项研究将有助于教育患者保留阻生牙的风险，根据科学事实，为了将风险降至最低，并评估病理改变与嵌塞深度和嵌塞牙齿角度位置的相关性。
