Abstract

AIM: The aim of the present study was to evaluate the timing and sequence of the eruption of deciduous teeth in Indian children.

METHOD: This cross-sectional study focused on children aged 5-36 months. One hospital was randomly selected from four geographic zones of the city. A total of 400 children from each hospital, fulfilling the inclusion criteria, constituted the sample. The examination was carried out by a single, trained examiner. The tooth was recorded as "present" or "absent" on the day of examination. The mean age of emergence was calculated using a probit model. Independent sample t-test was used to assess the statistical significance of differences in the mean age of tooth emergence.

RESULTS: The deciduous mandibular central incisor was the first tooth to erupt in the oral cavity (8.15±1.69 months). Girls showed delayed eruption compared to boys; however, no interarch variation was observed in the mean age of tooth eruption. There was also no difference in the sequence of eruption of deciduous teeth, as reported in other studies.

CONCLUSIONS: The present study establishes a chronological table for the eruption of deciduous teeth in Indian children. There was delayed eruption of deciduous teeth when compared to the reference ranges of Western populations.
