Abstract

BACKGROUND

This study's objectives are to ascertain the frequency of congenital tooth missing and evaluate the relationship between gender and side characteristics.

METHOD

This retrospective study involved participants who attended private dental clinics as well as a dental college in Hail, Saudi Arabia. Out of the 1,150 patients examined, 494 (220 males and 274 females) fulfilled the inclusion criteria. Different types of tooth agenesis were evaluated and classified into the following categories: mild (one or two teeth missing), moderate (three to five teeth missing), and severe (six or more teeth missing). The analysis did not include third molars. The existence of retained primary teeth was noted, along with any dental abnormalities accompanying tooth agenesis. Statistical analysis was conducted utilizing the chi-square test and Fisher's exact test to explore possible relationships between variables. A significance level of 5% (alpha = 0.05) was utilized.

RESULTS

Out of the 1150 panoramic radiographs that were examined, 494 individuals (220 (44.5%) males and 274 (55.5%) females) met the criteria for inclusion. The prevalence of congenitally missing permanent teeth was 65 (13.2%) in the study sample. The prevalence of congenitally missing teeth were more incidence in maxilla 36 (56.3%) than mandible 28 (43.8%). There is statistically significant association between the occurrence of congenitally missing teeth and gender or arch (p < 0.05). The prevalence of dental anomalies was similar in both sides. There are not a statistically significant association (p > 0.05) between the occurrence of congenitally missing teeth and side. The second premolar was the most commonly missing (7.3%). The retained deciduous teeth was shown to be the most common dental anomaly, with a prevalence of 15 (23.4%).

CONCLUSIONS

The prevalence of congenitally missing teeth fell within the range reported in previous studies. Second premolars were the most frequently congenitally missing teeth, with maxillary teeth more commonly affected than mandibular ones.

摘要

背景

本研究的目的是确定先天性牙齿缺失的频率，并评估性别与患牙侧特征之间的关系。

方法

这项回顾性研究涉及在沙特阿拉伯海勒的私人牙科诊所和一所牙科学院就诊的参与者。在接受检查的1150名患者中，494名（220名男性和274名女性）符合纳入标准。对不同类型的牙齿发育不全进行评估并分类如下：轻度（缺失一或两颗牙齿）、中度（缺失三至五颗牙齿）和重度（缺失六颗或更多牙齿）。分析不包括第三磨牙。记录乳牙滞留的情况以及伴随牙齿发育不全的任何牙齿异常。采用卡方检验和费舍尔精确检验进行统计分析，以探讨变量之间可能的关系。使用的显著性水平为5%（α = 0.05）。

结果

在检查的1150张全景片中，494人（220名（44.5%）男性和274名（55.5%）女性）符合纳入标准。研究样本中先天性恒牙缺失的患病率为65例（13.2%）。上颌先天性缺牙的患病率为36例（56.3%），高于下颌的28例（43.8%）。先天性缺牙的发生与性别或牙弓之间存在统计学上的显著关联（p < 0.05）。两侧牙齿异常的患病率相似。先天性缺牙的发生与患牙侧之间不存在统计学上的显著关联（p > 0.05）。第二前磨牙是最常缺失的牙齿（7.3%）。乳牙滞留是最常见的牙齿异常，患病率为15例（23.4%）。
