Journal Title: International Archives of Integrated Medicine - Year 2016, Vol 3, Issue 5
Abstract
Introduction: Tooth eruption marks a milestone in a child’s development and is synchronous with growth and development of the craniofacial complex. Thus, the present study was carried to evaluate the timing and sequence of eruption of deciduous teeth among children of India. Materials and methods: The present study was carried out on 60 children (30 boys and 30 girls), aged between 5 till the emergence of II deciduous molar in the oral cavity, who were local residents, born and residing in that area and were visited regularly at monthly intervals at their homes. All the data were compiled and tabulated using the SPSS software package version 18. Comparison was made between the data obtained and the standard tooth eruption table. The Student t’ test was used to assess the significance of difference in the mean age of tooth eruption with p value of <0.005 as significant value. Results: Comparing the maxillary and mandibular arches, mandibular central incisor at 8.85 ± 1.05 was the first tooth to erupt and maxillary second molar was erupted at 28.12 ± 1.5 months were the last deciduous tooth to erupt in the oral cavity. Females showed delayed eruption compared to males in case of anterior teeth, and males showed delayed eruption in case of posterior deciduous teeth. Though the difference was not significant (p> 0.05), there was a systematic tendency for early eruption of left sided primary teeth, though the difference was not significant. Conclusion: The present study found delay in eruption. Hence, studies conducted to evaluate time to time estimation of variation of eruption sequence among different populations is important for general dental practitioners, and pediatric dentists to contend with the anxiety of the parents.
