Impacted premolars are a common occurrence. This report describes how an impacted UR5, which was easily palpable and predicted to erupt spontaneously, caused extensive root resorption in the adjacent UR6.
This case highlights the importance of a thorough assessment of the position of all impacted premolars, irrespective of whether they can be palpated or not. This is especially important when planning orthodontic extractions, where the use of up-to-date appropriate radiographs is essential.
埋伏阻生的前磨牙很常见。本报告描述了一颗易于触及且预计会自行萌出的右上颌第二前磨牙(UR5)如何导致相邻的右上颌第一磨牙(UR6)发生广泛的牙根吸收。
该病例强调了全面评估所有埋伏阻生前磨牙位置的重要性,无论它们是否可触及。在计划正畸拔牙时这一点尤为重要,此时使用最新的合适牙片至关重要。
