First lower premolars are the teeth with greater variations following third molars. Fifty four first premolars extracted by orthodontic indication from patients in Temuco, Chile, were studied and classified by age, sex and maxillar and mandible location. The following parameters were measured: vestibular-palatine diameter (VP), mesiodistal (MD) diameter, coronary height (C-O), root length and total length. The data were statistically analyzed and tabulated. The results exhibited that first upper premolars showed higher values in the VP diameter and root length compared with the lower, noting significant differences. Further, male sex showed higher values on most measures compared with females, except in root length. Finally a difference in root length was observed between first upper and lower premolars.
