The presence of this condition specifically in the mandibular anterior region is reported very infrequently. This case report presents the case of a 9 years old non-syndromic male with missing mandibular central incisors and an erupted mandibular mesiodens along with the review of literature. To ensure optimum function and aesthetics, cosmetic recontouring was performed after oral prophylaxis. This is the ninth case reported in the dental literature till date, with the two anomalies manifesting in the anterior region of the mandible. This article also discusses the review of literature of concomitant hypo-hyperdontia.展开更多
牙齿数目异常是口腔常见疾病,可表现为牙齿数目过多(多生牙)和牙齿数目不足(先天缺牙),2种情况可单独发生,也可在同一个体中同时发生。Camilleri将这种既有多生牙又先天缺牙的疾病称为少牙多牙症(comcomitant hypodontia and hyperdonti...牙齿数目异常是口腔常见疾病,可表现为牙齿数目过多(多生牙)和牙齿数目不足(先天缺牙),2种情况可单独发生,也可在同一个体中同时发生。Camilleri将这种既有多生牙又先天缺牙的疾病称为少牙多牙症(comcomitant hypodontia and hyperdontia,CHH),CHH是一种较为少见的疾病。目前病因不明确,患病率差异较大,男性发病率高于女性。可伴发多种综合征和其他牙齿异常等。目前关于CHH的研究多以病例报道为主,本文综合国内外的相关研究,对其病因、临床表现、诊断、影响和治疗原则作一综述。展开更多
