The occurrence of triplication in the deciduous teeth is rare. However, it can cause several problems in primary dentition, alteration of development, and eruption of permanent successors. : A three-year-old boy presented with an exuberant acute periapical abscess in the left front teeth region of the upper jaw. Examination revealed a presence of a triple tooth involving the central and lateral left primary incisors and a supernumerary tooth. Radiographs showed that the fused teeth had separate roots, pulp chambers and root canals. The implemented treatment was extraction under local anesthesia. After 2 years of observation, surgical exposure of the crowns of the permanent maxillary central incisor was performed. After seven years, the permanent dentition was completed without any sequelae. : Triple tooth, as observed in this case report, results from the union of three tooth germs, potentially influenced by physical, hereditary, or environmental factors, leading to esthetic and functional issues and increased susceptibility to caries. Treatment is challenging, requiring preventive care, complex endodontic procedures, and, in some cases, extraction with space maintenance to avoid future orthodontic complications. Early diagnosis, an adequate treatment plan and clinical monitoring should be performed, aiming at preventing the possible disturbances.
乳牙出现三重复合的情况较为罕见。然而，它会在乳牙列中引发一些问题，影响发育以及恒牙胚的萌出。一名三岁男孩上颌左侧前牙区出现了严重的急性根尖脓肿。检查发现左侧上颌乳中切牙和侧切牙出现了三重复合牙以及一颗多生牙。X光片显示融合牙有独立的牙根、髓腔和根管。实施的治疗是在局部麻醉下拔牙。经过两年观察，对上颌恒中切牙进行了冠部手术暴露。七年后，恒牙列发育完成，未出现任何后遗症。本病例报告中观察到的三重复合牙是由三个牙胚融合而成，可能受物理、遗传或环境因素影响，导致美观和功能问题，且患龋易感性增加。治疗具有挑战性，需要预防性护理、复杂的牙髓治疗程序，在某些情况下还需要拔牙并进行间隙保持，以避免未来的正畸并发症。应进行早期诊断、制定适当的治疗计划并进行临床监测，以预防可能出现的干扰。
