Aim: The aim of the study was to investigate the caries experience in primary molars and first permanent molars among a group of Egyptian children. - Methodology: The study was carried out on 68 patients with age range from 6-9 years old, attending the Outpatients{u2019} Clinic of Pediatric Dentistry Department, Faculty of Dentistry, Cairo University. A specially designed assessment chart was filled for each child. The child teeth were cleaned using sterile gauze, then dental examination was performed on dental unit using disposable diagnostic set, the caries was assessed using deft index for primary teeth and DMFT index for permanent teeth. Also, a bite-wing radiograph was obtained for each child in order to diagnose proximal caries.- Results: As regards gender, male and female patients were counted as (42.65%) and (57.3%) respectively, it was revealed that there was no significant difference between genders and caries prevalence as P-value > 0.05. Regarding age(years) there was significant difference between all ages as deft and DMFT scores were higher in older ages. The caries prevalence was higher in primary molars with mean deft of (3.02± 1.17), while in permanent molars the mean DMFT was (1.13±1.18). Regarding the relation between caries experience in primary molars and first permanent molars, a positive correlation was found
