title: Short term comparative evaluation of antimicrobial efficacy of tooth paste containing lactoferrin, lysozyme, lactoperoxidase in children with severe early childhood caries: a clinical study.
abstract: OBJECTIVE
  The present study is conducted to compare the anti-microbial efficacy of tooth paste containing lactoferrin, lysozyme, lactoperoxidase (BioXtra ®), a 500ppm fluoride tooth paste, and a non fluoridated tooth paste in children with Severe Early Childhood Caries (S-ECC).
  
  
  METHODS
  Study group included 30 children with S-ECC aged 3-5 years. Subjects were randomly selected & divided into three groups of ten each. Group I: Non-fluoride tooth paste, Group II: 500 ppm fluoride tooth paste, Group III: tooth paste containing lactoferrin, lysozyme & lactoperoxidase. Estimation of salivary S. mutans and L. acidophilus levels was accomplished by collecting salivary samples and inoculated on Mitis Salivarius Bacitracin agar (MSB) and Rogosa SL media. Colony Forming Units (CFUs) were counted and the results were tabulated and subjected to statistical analysis.
  
  
  RESULTS
  Brushing with tooth paste containing lysozyme, lactoferrin and lactoperoxidase after a week showed highly significant reduction in the CFU counts of both salivary S. mutans and L. acidophilus (p<0.001), whereas 500ppm fluoride tooth paste showed a highly significant reduction in the S. mutans levels (p<0.001), but a significant reduction in L. acidophilus count (p<0.01). Non-fluoride tooth paste showed a highly significant reduction in S. mutans (p<0.001) only, but reduction in the L. acidophilus levels was insignificant (p<0.05).
  
  
  CONCLUSIONS
  The present study revealed that tooth paste containing lactoferrin, lysozyme, and lactoperoxidase was highly significant in reducing the salivary levels of mutans Streptococci and L. acidophilus in children with S-ECC.
