There are still many doubts about anterior inferior crowding and indications of mandibular third molar extraction, although it is very studied subject in the literature. The aim of this study was to evaluate the perceptions of oral maxillofacial surgeons (OMFSs) and orthodontists about anterior inferior crowding and indications of mandibular third molar extraction.
A web-based survey was developed and sent to professionals in order to collect their opinion about the fact that third lower molars cause crowding and questions about the indication of third molars for orthodontic treatment. Descriptive analysis was performed and Chi-square or G tests were applied with a 95% confidence interval.
The study included a total of 218 participants, of whom 115 were OMFSs and 103 were orthodontists. The results showed that 56.5% of OMFSs and 35.0% of orthodontists believe that the lower third molars cause anterior inferior crowding (p<0.001). A total of 91.3% of OMFSs and 70.9% of orthodontists indicate the extraction of lower third molars to aid orthodontic treatment (p<0.001).
It can be concluded that in being an oral maxillofacial surgeon, a higher odds ratio is observed to consider that lower third molars cause dental crowding compared to those who are orthodontist. The indication of exodontia of lower third molars for orthodontic treatment was more frequent among OMFSs when compared to orthodontists.
尽管文献中对此进行了大量研究，但对于下颌第三磨牙前倾拥挤的原因及其拔牙适应证仍存在诸多疑问。本研究旨在评估口腔颌面外科医生（OMFSs）和正畸医生对下颌第三磨牙前倾拥挤及其拔牙适应证的看法。
采用网络问卷调查的方式收集专业人士对下颌第三磨牙导致拥挤的看法及下颌第三磨牙是否为正畸适应证的相关问题。采用描述性分析，应用卡方检验或 G 检验，置信区间为 95%。
共纳入 218 名参与者，其中 115 名为 OMFSs，103 名为正畸医生。结果显示，56.5%的 OMFSs 和 35.0%的正畸医生认为下颌第三磨牙会导致前牙拥挤（p<0.001）。91.3%的 OMFSs 和 70.9%的正畸医生表示会为辅助正畸治疗而拔除下颌第三磨牙（p<0.001）。
与正畸医生相比，口腔颌面外科医生更倾向于认为下颌第三磨牙会导致牙列拥挤。与正畸医生相比，口腔颌面外科医生更倾向于将下颌第三磨牙拔除作为正畸治疗的适应证。
