This article summarises recently updated guidelines produced by the Clinical Governance Directorate of the British Orthodontic Society through the Clinical Standards Committee of the Faculty of Dental Surgery, Royal College of Surgeons of England (FDSRCS) on the extraction of first permanent molars in children. The first permanent molar is susceptible to chronological enamel defects, molar-incisor hypomineralisation and caries, which may necessitate enforced extraction in the developing dentition. In the right circumstances, the extraction of these teeth can be followed by successful eruption of the second permanent molar and ultimately, third molar eruption to complete the molar dentition. For this reason, elective extraction of first permanent molars with a questionable long-term prognosis should be considered when planning enforced extractions. However, a number of factors can influence the decision-making process, including the necessity for a general anaesthetic to allow extraction, potential cooperation with restorative or orthodontic treatment and likely future preventative practice within the family. Moreover, the presence of any underlying malocclusion also needs to be evaluated within the context of extraction planning. The current available evidence has been evaluated and awarded a grade based upon those recommended by the Scottish Intercollegiate Guidelines Network.
本文总结了英国正畸学会临床治理局通过英格兰皇家外科医学院牙外科系临床标准委员会(FDSRCS)制定的关于儿童第一恒磨牙拔除的最新指南。第一恒磨牙易出现按年龄顺序排列的釉质缺陷、磨牙-切牙矿化不全和龋齿,这可能需要在牙列发育过程中强制拔除。在合适的情况下,拔除这些牙齿后,第二恒磨牙可能成功萌出,最终第三恒磨牙萌出以完成磨牙牙列。因此,在计划强制拔牙时,应考虑对长期预后存疑的第一恒磨牙进行选择性拔除。然而,许多因素会影响决策过程,包括拔牙是否需要全身麻醉、与修复或正畸治疗的潜在配合以及家庭未来可能的预防措施。此外,在拔牙计划中还需要评估是否存在任何潜在的错颌畸形。已根据苏格兰跨学院指南网络推荐的标准对现有证据进行了评估并给出了等级。
