The variables considered were sex, age, presence of supernumerary teeth, tooth type according to location, location, root development and position. Results: The presence of supernumerary teeth was 2.42% IC95% (1.36-3.46) which correspond to 21 teeth and 90% of the cases only presented one tooth, the mesiodens being the most found tooth, and the male population is the most affected with a 1.5:1 ratio. Conclusions: The prevalence of supernumerary teeth in patients attending consultations between the ages of 7 to 16 years at the Universidad Santo Tomàs headquarters Floridablanca is 2.42%.
