Background: Premature infants have higher risks of infection due to their underdeveloped immune systems and changes to the oral cavity's normal flora colonization.
Purpose: To assess the effect of oral colostrum application on the condition of the mouth and the incidence of late-onset sepsis (LOS) among premature infants.
Methods: In this randomized controlled trial, 70 newborn premature infants were randomly allocated to colostrum or sterile water groups.
