Chronology And Sequence Of Eruption Of Deciduous Teeth In Children Of Rajnandgaon, Chhattisgarh

There has been a wide variation in the time and sequence of primary teeth emergence among different population, ethnic and racial groups. The present study conducted to determine the chronology of eruption of deciduous teeth in children of Rajnandgaon, Chhattisgarh. A Prospective observational cohort study with sample of 408 chhattisgarhi children aged between 0-48 months was selected by simple random sampling method. Other variables such as type of delivery, weight, height, type of feeding pattern, duration of feeding, type of milk products used, use of teething syrups and number of teeth erupted were recorded. Clinical examination was done under natural illumination. It was found that mandibular central incisor was the first tooth to erupt at 10.15 -10.42 months followed by maxillary central incisor at 11.4 months showing the mean difference of 4 months. Eruption of primary tooth is delayed as compared to standard eruption chart among Chhattisgarh children. Significant difference was found for the type of feeding and duration of feeding for the children with p=0.04 and 0.01 respectively in regression analysis. This study also justify that the environmental and systemic factors has shown influence on eruptive process.
