The present study aimed to investigate the correlation between dental caries and its consequences in terms of pulp involvement, ulceration, fistula, abscess utilizing (PUFA/pufa) indices and specific Body Mass Index (BMI) with reference to age in a group of Egyptian Children. A total of 201 children from Pediatric Dentistry Department in Cairo University having PUFA/pufa ≥1 were included. PUFA/pufa index was used according to the standard procedure to assess the consequence of untreated dental decay. The BMI percentile was computed using Centers for Disease Control and Prevention (CDC) growth charts. The correlation between PUFA/pufa and body mass index (BMI) showed no significance correlation (P = 0.740).
