Summary

Results of rostral tooth development determined both visually and by post-mortem radiographic examination were used to provide age ranges and median ages for stages which could be seen between 1 and 2 years old. These showed that intra-oral eruption of the permanent rostral teeth was of little value in age estimation during the second year of life. However, utilizing the stages of tooth development which could be seen radiographically the maximum age range before differentiation was 5 months (1 year 1 month from 1 year 6 months and 1 year 5 months from 1 year 10 months). Thus it appeared that rostral tooth radiography was of more use in age estimation than intraoral eruption of the permanent teeth.
