Macrodontia is a dental anomaly pertaining to the increased size of a tooth or multiple teeth. Double teeth are dental abnormalities concerning tooth morphology and the term traditionally refers to geminated or fused teeth. These anomalies may manifest in both primary and permanent dentitions and usually become apparent in childhood. They may cause a variety of clinical sequelae, including orthodontic complications, such as crowding, ectopic eruption of adjacent teeth and periodontal concerns. Double teeth are also at a higher risk of developing caries. The aesthetic implications of these dental anomalies can affect the psychosocial development of a patient. This, together with the range of functional repercussions, can often need dental treatment to improve quality of life. The functional and aesthetic complexities that may arise in the affected patients can require endodontic, restorative, surgical and/or orthodontic input as part of the management strategy and execution. We present four clinical cases of paediatric patients where a range of management approaches were employed for both macrodontia and double teeth.
巨齿症是一种牙齿或多颗牙齿增大的牙齿异常。双牙是一种涉及牙齿形态的牙齿异常，术语传统上是指双生牙或融合牙。这些异常可能在乳牙和恒牙中表现出来，通常在儿童时期就会显现出来。它们可能导致多种临床后果，包括正畸并发症，如拥挤、邻牙异位萌出和牙周问题。双牙也更容易发生龋齿。这些牙齿异常的美学影响会影响患者的社会心理发展。再加上一系列的功能影响，通常需要进行牙科治疗以提高生活质量。受影响患者可能出现的功能和美学复杂性可能需要牙髓、修复、手术和/或正畸方面的介入，作为管理策略和实施的一部分。我们介绍了四名儿科患者的临床病例，这些患者都存在巨齿症和双牙的情况，采用了一系列的管理方法。
