  1. Note: In total, 7 deciduous teeth was recorded as missig teeth due to caries but they were not coded as dental caries following the standard procedure of the school health checkups. In total, 181 cases were identified where deciduous tooth and its permanent successor were growing in the same position. Although 1 permanent successor was identified as decayed, missing or filled, it is likely that permanent successors were just grown and we dropped permanent successors from the analysis in Table 4 and not presented in all teeth category in this table.
