Abstract

Introduction: Hypodontia is the most prevalent dental anomaly that might cause clinical complications. The aim of this study is to assess the prevalence of hypodontia in relation with sex in permanent teeth, skeletal malocclusion and dental crowding among orthodontic patients admitted to Ahvaz Dental School. Materials and Methods: In this descriptive cross-sectional study, dental casts, panoramic radiographs and lateral cephalograms related to patients that were admitted to Department of Orthodontics of Ahvaz Dental School during 2018-2019 were investigated, to establish the existence of hypodontia, type of skeletal relationship, age, sex and dental crowding in the permanent dentition. The data were analyzed using a chi-square test in IBM SPSS Statistics for Windows, version 25 with statistical significance set at p value < 0.05. Results: Among 331 patients which were included 257 females (77.65%) and 74 males, prevalence of hypodontia was 9.4% (31 patients, 10.5% in females, 5.5% in males). The difference between the genders in term of hypodontia was not significant (p value = 0.257). This condition was existed from the dental and skeletal relationship point of view: hypodontia was observed in 19 patients (61.4%) with class Ⅰ relationship, 9 patients (29%) with skeletal class Ⅱ and 3 patients (9.6%) with skeletal class skeletal class ⅠⅠⅠ relationship. The difference between skeletal relationship and hypodontia was not significant (p value = 0.370). Dental crowding was observed in 24 patients (77.4%). There was not significant difference between dental crowding and hypodontia (p value = 0.276). Conclusion: Hypodontia was more prevalent in females but there was no significant difference between the prevalence of hypodontia in males and females. Previous studies have shown that the prevalence of hypodontia in Iran similar to current study.

Ahvaz牙科学校住院患者基于性别、牙齿和骨骼关系的下颌缺损患病率评估
牙下畸形是最常见的牙齿畸形,可引起临床并发症。本研究的目的是评估在Ahvaz牙科学校接受正畸治疗的患者中,恒牙、骨骼错颌和牙齿拥挤与性别有关的下颌畸形患病率。材料与方法:本研究采用描述性横断面研究方法,对2018-2019年在Ahvaz牙科学校正畸科就诊的患者的牙模、全景x线片和侧位头颅片进行调查,以确定恒牙列是否存在牙缺损、骨骼关系类型、年龄、性别和牙齿拥挤情况。使用IBM SPSS Statistics for Windows, version 25对数据进行卡方检验,p值< 0.05。结果:331例患者中,女性257例(77.65%),男性74例,下颌畸形患病率为9.4%(31例,女性10.5%,男性5.5%)。在下颌畸形方面,性别间差异无统计学意义(p值= 0.257)。这种情况从牙骨关系的角度来看是存在的:骨性关系Ⅰ类有19例(61.4%),骨性关系Ⅱ类有9例(29%),骨性关系ⅠⅠⅠ类有3例(9.6%)。骨性关系与下颌发育差异无统计学意义(p值= 0.370)。24例(77.4%)出现牙齿拥挤。牙体拥挤与牙下发育差异无统计学意义(p值= 0.276)。结论:下颌畸形以女性多见,但男女间无显著性差异。先前的研究表明,下颌畸形在伊朗的患病率与本研究相似。
