摘要

背景/目的上颌第一恒磨牙(FPM)异位萌出(EE)的病因仍不清楚,且存在争议。本研究旨在探讨导致儿童上颌第一恒磨牙异位萌出的牙齿和骨骼因素。受试者被分配到异位萌出组(EEG)和正常萌出组(NEG)。通过角度和线性指数测量头颅侧位X光片和全景X光片。骨骼Ⅲ级错颌畸形的受试者更容易被诊断为上颌FPM EE。EEG和NEG的SNA、ANB、FMIA、Wits、Ptm-A、ANS-PNS、过咬合和过咬合均有显著差异。结论男性性别、骨骼Ⅲ类错颌畸形、上颌FPM中位倾斜、上颌骨发育不良以及上颌牙槽骨后区长度不足与上颌FPM EE有关。

Ectopic eruption of maxillary first permanent molars: Risk factors and association with alveolar and maxillary characteristics on children

Background/purpose

The etiology of the ectopic eruption (EE) of the maxillary first permanent molars (FPM) remains unclear and controversial. This study was designed to explore the dental and skeletal factors for EE of the FPM in children.

Materials and methods

Children aged 6–10 years were recruited to this study. Subjects were assigned to the ectopic eruption group (EEG) and the normal eruption group (NEG). Lateral cephalometric radiographs and panoramic radiographs were measured by angular and linear indices.

Results

The prevalence of EE of maxillary FPM was higher in males and at younger ages. Subjects with skeletal class III malocclusion were more likely to be diagnosed with EE of maxillary FPM. The SNA, ANB, FMIA, Wits, Ptm-A, ANS-PNS, overbite, and overjet were significantly different between the EEG and the NEG. The length of the posterior region of the maxillary alveolar bone, U6-OP, and eruptive angulation of the maxillary FPM were statistically different between the two groups.

Conclusion

Male sex, skeletal class III malocclusion, mesial inclination of the maxillary FPM, hypoplasia of the maxilla, and insufficient length of the posterior region of the maxillary alveolar bone were related to EE of the maxillary FPM.

期刊介绍: he Journal of Dental Sciences (JDS), published quarterly, is the official and open access publication of the Association for Dental Sciences of the Republic of China (ADS-ROC). The precedent journal of the JDS is the Chinese Dental Journal (CDJ) which had already been covered by MEDLINE in 1988. As the CDJ continued to prove its importance in the region, the ADS-ROC decided to move to the international community by publishing an English journal. Hence, the birth of the JDS in 2006. The JDS is indexed in the SCI Expanded since 2008. It is also indexed in Scopus, and EMCare, ScienceDirect, SIIC Data Bases. The topics covered by the JDS include all fields of basic and clinical dentistry. Some manuscripts focusing on the study of certain endemic diseases such as dental caries and periodontal diseases in particular regions of any country as well as oral pre-cancers, oral cancers, and oral submucous fibrosis related to betel nut chewing habit are also considered for publication. Besides, the JDS also publishes articles about the efficacy of a new treatment modality on oral verrucous hyperplasia or early oral squamous cell carcinoma.
