The guiding principle in managing trauma to the primary dentition is potential sequelae to the permanent tooth. If the risk to the permanent tooth is great, the primary tooth should be removed. If esthetics are a concern to the parent, a number of appliances can be fabricated to temporarily manage this issue. It is important that parents realize that the desire to maintain optimum esthetics by maintaining a significantly injured primary tooth can, in many cases, cause more damage to the permanent tooth. Where avulsions have occurred, the old adage "when in doubt, leave it out" is still perhaps the most reliable advice.
处理乳牙外伤的指导原则是对恒牙的潜在后遗症。如果恒牙面临的风险很大，就应该拔除乳牙。如果家长担心美观问题，可以制作一些矫治器来临时解决这个问题。重要的是，家长要认识到，在很多情况下，出于保持严重受伤乳牙以维持最佳美观效果的愿望，可能会对恒牙造成更多损害。对于发生牙齿完全脱出的情况，古老的格言“拿不准时，就不拔”可能仍然是最可靠的建议。
