The canine plays an important role in dentofacial aesthetics and function. It supports the base of the alar and upper lip, which are necessary for smile aesthetics. When impacted, these functions are lost, leading to low self-esteem and overall poor health-related quality of life. This study was designed to determine the prevalence and pattern of impacted canines in the southwestern region, Kingdom of Saudi Arabia.
This was a retrospective study carried out in a dental center in the southwestern region of Saudi Arabia. A total of 2000 panoramic radiographs were screened, and all patients with impacted canines were further screened both clinically and radiologically (cone beam CT). Demographics, position, laterality, and relationships to the midline were retrieved and recorded. Cone beam CT was used to diagnose palatal or labial impactions. The data were analyzed using IBM SPSS Statistics for IOS Version 25 (Armonk, NY: IBM Corp).
A total of 2000 panoramic radiographs were screened, out of which 107 cases were found to have impacted canines, giving a prevalence of 5.35%. There were 38 males and 69 females with a M:F ratio of 1:1.8. Their age ranged from 15 to 75 years with a mean ± SD age of 20.4 ± 11.1. There were more affected maxillary canines (99 (92.5%)) compared with mandibular canines (8 (7.5%)). Palatal impaction positions were more frequent than labial impactions.
The prevalence of canine impaction in the southwestern region of Saudi Arabia was 5.35%, with a female preponderance and more palatal positions. The impactions occurred more unilaterally on the left side than on both sides.
犬齿在牙颌面美学和功能中起着重要作用。它支撑鼻翼和上唇基部,而这对于微笑美学是必不可少的。当犬齿阻生时,这些功能丧失,导致自尊心低落以及与健康相关的总体生活质量较差。本研究旨在确定沙特阿拉伯王国西南部地区犬齿阻生的患病率和模式。
这是一项在沙特阿拉伯西南部地区的牙科中心进行的回顾性研究。共筛查了2000张全景X线片,所有犬齿阻生患者均进一步进行临床和影像学检查(锥形束CT)。收集并记录人口统计学信息、位置、侧别以及与中线的关系。使用锥形束CT诊断腭侧或唇侧阻生。使用IBM SPSS Statistics for IOS版本25(纽约州阿蒙克:IBM公司)对数据进行分析。
共筛查了2000张全景X线片,其中107例被发现有犬齿阻生,患病率为5.35%。男性38例,女性69例,男女比例为1:1.8。他们的年龄在15至75岁之间,平均年龄±标准差为20.4±11.1岁。上颌犬齿受累者(99例(92.5%))多于下颌犬齿受累者(8例(7.5%))。腭侧阻生位置比唇侧阻生更常见。
沙特阿拉伯西南部地区犬齿阻生的患病率为5.35%,女性居多,且腭侧位置更多。阻生更常见于左侧单侧而非双侧。
