Objective: The size of primary teeth in the current Brazilian population has not been studied yet; the aim of this in vitro study was to document the size and variation of deciduous teeth from a tooth bank in São Paulo, Brazil. Methods: A sample of 1,095 deciduous teeth was obtained from a tooth bank at the Dental School of the University of Sao Paulo. The measurements were made with a digital caliper. Only unworn, undamaged teeth were measured. Results: At mesiodistal diameter, maxillary central incisor showed the highest variation and the mandibular first molar the least. In buccolingual sizes, mandibular second molar was the tooth with the highest variability. Conclusion: This study provides a record of primary tooth sizes in Brazilian children. There was an evident variation of size of the primary teeth.
