Algunos autores han reportado la prevalencia, los métodos de diagnóstico y el tratamiento para la EPA; hoy en día, el uso de cone-beam computed tomography (CBCT) ha sido una herramienta fundamental en el plan de tratamiento al proporcionar resultados objetivos y de calidad, siendo éste el objetivo principal de este caso clínico.  Material y métodos: Paciente de sexo femenino con EPA en el sector anterior superior (pieza dental 1.3 a 2.3); se realizó un protocolo para obtener las medidas del tamaño de la corona clínica, longitud de la unión cemento-esmalte (UCE), cresta ósea y cantidad de tejido gingival con la técnica tradicional clínica de sondeo y con el uso del CBCT, se registraron todas las medidas y se procedió a analizar los resultados obtenidos para posteriormente realizar la cirugía de alargamiento de corona. Los resultados mostraron con las medidas de las diferencias entre el sondeo clínico y el CBCT una media aritmética de 0.6876, lo cual significa que es el valor promedio de las diferencias entre ambas técnicas y una desviación estándar de ± 0.4997 que significa el grado de dispersión de la variabilidad. Con estos resultados se puede concluir que la diferencia entre la medida de la técnica de sondeo clínico tradicional y el CBCT es muy poca, por lo cual el tomógrafo digital proporciona una información más objetiva.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract: Passive altered eruption (PAE) is a pathological condition that can create concerns in the patient due to the unsightly impact of this mucogingival deformity. Some authors have reported the prevalence, methods of diagnosis and treatment for the PAE; the use of cone-beam computed tomography (CBCT) has been a fundamental tool in the treatment plan of this type of pathology providing objective and quality results, being this the main objective of this clinical case.  Material and methods: Female patient diagnose with PAE, in the upper anterior sector (tooth 1.3 to 2.3), the protocol was performed to obtain measurements of the size of the clinical crown, Cementum-Enamel Junction (CEJ) length, crestal bone and amount of gingival tissue with the traditional clinical technique and with the use of the CBCT, all the measurements were recorded and the results obtained were analyzed to perform the crown lengthening surgery. The results obtained with the measures of the differences between the clinical traditional technique and the CBCT gave an arithmetic mean of 0.6876, which means this is the average value of the differences between the two techniques and a standard deviation of ± 0.4997 which means the degree of dispersion of the variability. With these results, it can be concluded that the difference between the traditional clinical sounding technique and the CBCT is very small, so the digital tomography study offers more objective information.]]></p></abstract>
