Aim: This study was done to evaluate association of caries in deciduous second molar and adjacent permanent first molar, tooth surface more involved in permanent first molar and to assess the parental awareness regarding the eruption of permanent first molar. Subjects and Methods: Three hundred and ten children (160 boys, 150 girls) of mixed dentition aged between 6 and 11 years were included. Presence or absence of paired association of caries in primary second molar and adjacent permanent first molar, of both the jaws, were noted. Parental awareness regarding the child's dentition was asked by pointing the maxillary and mandibular permanent first molar. Results: Pearson Chi-square test was used. Significance was noted in both sexes between paired nonassociation of caries in mandibular primary second molar and mandibular permanent molar (P =0.01) and paired nonassociation of caries in primary maxillary second molar and maxillary permanent first molar in girls only (P =0.04). Parental awareness that permanent first molar has erupted was 24.83% and not to be exfoliated and replaced was 22.9% for both the sexes. In permanent teeth of both the sexes, the occlusal surface was more involved with caries in maxillary teeth; the buccal surface was more involved in mandibular teeth. About 10% of the sample did not have caries in both maxillary and mandibular permanent first molar. Conclusions: Paired association of caries of primary second molar and permanent first molar though found in large number of cases was not significant. It is clear that parental awareness is less regarding the child's oral health. Thus, community-based awareness program has to be conducted to emphasize on pediatric oral health status and care.
