Determinación de estándares Cefalométricos de las diferentes etnias de Ecuador

Cephalometry with lateral skull radiography is a routine diagnostic method in orthodontic and maxillary orthopedic practice that under the metric problems and previously established proportions, establish an important part of the diagnosis in skeletal cephalic alterations called dentofacial deformities; The criteria specified above correspond mostly to the measures taken by Caucasian individuals, so it does not coincide with the exact average of the measures of the rest of the ethnic groups. Through this study, a representative sample of the Ecuadorian population, with its different ethnicities, was taken to establish the arithmetic mean of its craniofacial measures and proportions, so that it is counted on the one that represents the normality of each representative ethnic group of Ecuador . The estimate of the population sample consists of 30 individuals by ethnicity from 18 to 30 years of age, without previous aesthetic, reconstructive and / or craniofacial symptoms, maxillary orthopedic appliances, traumatic or syndromic sequelae diagnosed. This population will perform a lateral skull x-ray that will then be quantified with Ricketts Cephalometric analysis by means of Dolphin® software, obtaining through arithmetic average statistical tools and standard deviation of measurements and proportions by ethnic group with the program SPS®; The ethnicities to study will be: white, mestizo, Afro-Ecuadorian and indigenous.
