Evaluación del espesor del esmalte en primeras premolares y primeras molares permanentes

Abstract

Objective: to assess the thickness of the permanent human tooth enamel, in portions vestibular/palatal-lingual, according to the thirds coronal cervical, middle and incisal. Materials and Methods: A sample of 75 healthy teeth, divided into first premolars (n=25), first molars (n=25) and first molars (n=25). Were cut in strips of 1 mm thick in a digital cutting machine. The measurements were made according to the thirds coronal, cervical, middle and incisal, using a digital gauge to perform the measurement in (mm). A descriptive statistics (mean and standard deviation) of the study variables. Results: The increased thickness of the enamel on the vestibular sense is in the incisal third, with an average of 1.53 mm 0.20 belonging to the molars and the lower value is found in the cervical third with an average of 0.64 mm 0.08 corresponding to the first molars. While, in the palatal/lingual sense, the highest value found is in the incisal third with an average of 1.50 mm 0.19, belonging to the first molars, and the lowest value is in the cervical third with an average of 0.65 mm 0.09 belonging to the first molars. Conclusions: The thickness of the enamel on the vestibular sense as palatal/lingual is greater in the incisal third and lower in the cervical third for the three groups of dental pieces. This knowledge will allow for wear to the tooth in a more conservative doing treatments highly functional and aesthetic.
