Oligodontia or absence of teeth such as the Canines is rare and is often accompanied with several other missing teeth. This condition may also be accompanied with morphological and growth related changes in the teeth and the maxillofacial complex. Complete agenesis of the permanent canines in the maxilla and the mandible is extremely rare and occurs in association with syndromic oligodontia. Non-syndromic absence of canines however, is extremely rare and has only been reported twice. Studies have shown that the incidence of missing canines is more in females. This report describes a sporadic case of congenital absence of maxillary and mandibular bilateral canines. The patient reported to the clinic with a chief complaint of crowding and wanted alignment. On intra-oral examination it was observed that the patient had all permanent canines missing with no prior history of extractions, crowding in both the arches and class I molars on both sides. With no other symptoms fixed orthodontic therapy was planned for the patient with premolars substituted for the canines.
少牙症或牙齿缺失(如尖牙缺失)较为罕见,且常伴有其他多颗牙齿缺失。这种情况还可能伴有牙齿及颌面复合体的形态和生长相关变化。上颌和下颌恒牙尖牙完全缺失极为罕见,且与综合征性少牙症相关。然而,非综合征性尖牙缺失极为罕见,仅有两次报道。研究表明,女性中尖牙缺失的发生率更高。本报告描述了一例散发性先天性上颌和下颌双侧尖牙缺失病例。该患者因牙齿拥挤为主诉前来诊所就诊,希望进行牙齿排齐。口腔内检查发现,患者所有恒牙尖牙均缺失,无拔牙史,双侧牙弓均有拥挤,双侧磨牙均为I类关系。由于无其他症状,计划为该患者进行固定正畸治疗,用前磨牙替代尖牙。
