Abstract

Background: Tooth agenesis (TA) is the developmental absence of one or more teeth and is the most common craniofacial disorder in humans. Maxillary lateral incisor agenesis (MLIA) is a specific subtype of TA and can have esthetic, functional, and psychosocial implications for patients. The aim of this study was to evaluate the prevalence of MLIA amongst patients with non-syndromic tooth agenesis, as well as its association with other dental anomalies.

Materials and methods: The dental records of 240 patients with non-syndromic congenitally missing teeth treated at the University of Alabama at Birmingham Department of Orthodontics were reviewed. Dolphin Imaging software was used to identify missing teeth, microdonts, peg laterals, impactions, and transpositions. Data were analyzed using chi-square or Fisher's exact test. All the tests were two-sided at the significance level of 0.05 (SAS 9.4).

Results: In the patient cohort, MLIA prevalence was 37.5% (second most common) and no gender or ethnic differences were identified. We also observed the bilaterally missing lateral incisors more frequently than the unilateral presentation (p = 0.0006). Additionally, 62.5% of patients with unilateral MLIA displayed a contralateral tooth that was a peg (p = 0.0001); however, no association was found with other microdonts. Furthermore, of the 90 patients missing at least one maxillary lateral incisor, 42.2% were missing another tooth type and 10% of MLIA patients also had an impacted tooth (mainly maxillary canines). However, these were not statistically significant. Finally, no transposed teeth were found in our patients.

Conclusions: This study found that maxillary lateral incisors were the second most frequently missing teeth. When clinicians diagnose congenital absence of a maxillary lateral incisor, the patient should be evaluated for other missing teeth, peg lateral incisors, or potential impactions, especially maxillary canines.

上颌侧切牙的非综合征性下颌缺损及其与其他牙齿异常的关系。

背景:牙齿发育不全是一颗或多颗牙齿的发育缺失，是人类最常见的颅面疾病。上颌侧切牙发育不全(MLIA)是TA的一种特殊亚型，可对患者产生美学、功能和社会心理影响。本研究的目的是评估MLIA在非综合征性牙齿发育患者中的患病率，以及其与其他牙齿异常的关系。材料与方法:回顾在阿拉巴马大学伯明翰正畸科治疗的240例非综合征性先天性缺牙患者的牙科记录。使用Dolphin Imaging软件识别缺失的牙齿、小齿、栓侧、嵌塞和转位。数据分析采用卡方检验或费雪精确检验。所有检验均为双侧检验，显著性水平为0.05 (SAS 9.4)。结果:在患者队列中，MLIA患病率为37.5%(第二常见)，没有性别或种族差异。我们还观察到双侧侧切牙缺失比单侧切牙缺失更频繁(p = 0.0006)。此外，62.5%的单侧MLIA患者显示对侧牙为钉状(p = 0.0001);然而，没有发现与其他微齿相关。此外，在缺失至少一颗上颌侧切牙的90例患者中，42.2%的患者缺失另一种牙型，10%的MLIA患者还存在阻生牙(主要是上颌犬齿)。然而，这些没有统计学意义。最后，在我们的病人中没有发现移位的牙齿。结论:本研究发现上颌侧切牙是第二常见的缺失牙。当临床医生诊断先天性缺失上颌侧切牙时，应评估患者是否有其他缺失的牙齿、固定的侧切牙或潜在的嵌塞，特别是上颌犬齿。

期刊介绍： Progress in Orthodontics is a fully open access, international journal owned by the Italian Society of Orthodontics and published under the brand SpringerOpen. The Society is currently covering all publication costs so there are no article processing charges for authors. It is a premier journal of international scope that fosters orthodontic research, including both basic research and development of innovative clinical techniques, with an emphasis on the following areas: • Mechanisms to improve orthodontics • Clinical studies and control animal studies • Orthodontics and genetics, genomics • Temporomandibular joint (TMJ) control clinical trials • Efficacy of orthodontic appliances and animal models • Systematic reviews and meta analyses • Mechanisms to speed orthodontic treatment Progress in Orthodontics will consider for publication only meritorious and original contributions. These may be: • Original articles reporting the findings of clinical trials, clinically relevant basic scientific investigations, or novel therapeutic or diagnostic systems • Review articles on current topics • Articles on novel techniques and clinical tools • Articles of contemporary interest
