The prevalence, etiology and related complications of impacted maxillary and mandibular cuspids were studied among a convenient sample of 4,898 Saudi patients aged 13 years and older. Results indicate that 175 patients (3.6%) out of a sample had at least one impacted cuspid. Most (22.9%) possessed multiple involvement. Female patients were found to be more concerned about the problem (p < .001). The maxillary arches were usually affected more frequently. The most common location of maxillary cuspid impactions was palatal and the lingually located impaction in the mandible was found to be very rare. In most of the subjects the lack of arch space was the main etiological factor. Cuspid impactions were found to be occasionally associated with various unfavorable sequelae.
在一个由4898名13岁及以上沙特患者组成的便利样本中，对上颌和下颌阻生尖牙的患病率、病因及相关并发症进行了研究。结果表明，样本中有175名患者（3.6%）至少有一颗阻生尖牙。大多数患者（22.9%）存在多处受累情况。发现女性患者对该问题更为关注（p < 0.001）。上颌牙弓通常更易受到影响。上颌尖牙阻生最常见的位置是腭侧，而在下颌中舌侧阻生的情况非常罕见。在大多数研究对象中，牙弓间隙不足是主要的病因。发现尖牙阻生偶尔会伴有各种不良后遗症。
