Hypoplasia of primary and permanent teeth following osteitis and the implications of delayed diagnosis of a neonatal maxillary primary molar.
A 2-year-and-6-month-old Japanese girl with delayed eruption of a maxillary right primary canine and disturbance in the development of maxillary right primary molars was examined. The crown of the maxillary right first primary molar was severely decayed and hypoplastic. The periodontal tissues on the maxillary right posterior region were swollen and slight erythrogenic change was observed. Radiographic examination revealed a disturbance in the development of the permanent successor and the primary teeth in the maxillary right quadrant. According to the history, the maxillary right first primary molar had erupted on day seven after birth. It is suggested that the disturbance in development of the permanent successor and the primary teeth was secondary to osteitis caused by infection of the neonatal tooth. Appropriate dental treatment had not been administered for more than two years because the neonatal molar had not been diagnosed.
