Taurodontism in premolars and supernumerary teeth – report of an unusual association

Taurodontism is a tooth anomaly characterized by an enlarged pulp chamber and an apical displacement of the pulpal floor. It ́s more prevalent in molar teeth, with few cases reported in premolars. Objective: To describe bilateral taurodontism in lower premolars associated with supernumerary teeth in a young patient. Case report: 10-year old female patient evaluated in a routine appointment. Clinical examination revealed amelogenesis imperfecta in all first molars and lower left central incisor, fluorosis in upper central incisors and multiple carious lesions. Panoramic and periapical Xrays revealed bilateral taurodontic first lower premolars and bilateral supernumerary teeth between the roots of first and second lower premolars. Conclusion: Clinical examination of a pediatric patient must always be complemented by a panoramic X-ray. In specific cases other imagiologic exams should be realized. Early diagnose of these situations has particular importance since many developmental disturbances have their more visible manifestations in childhood.
