Proporción de los dientes anterosuperiores utilizando la sonda de proporciones de Chu

Abstract

The Chu proportion gauge is an instrument designed by Dr. Stephen Chu, which simultaneously measures the length and width of the anterior superior pieces and with an established proportion of 78%.

OBJECTIVES: To determine if the proportion of the anterior superior teeth of the students of the Faculty of Dentistry of the University of Cuenca is compatible with the proportion determined in the Chu´s gauge.

MATERIALS AND METHODS: 131 students from the Faculty of Dentistry of the University of Cuenca were evaluated. The Chu´s gauge was applied to each of the 6 anterosuperior teeth in each patient. The data obtained were recorded to be analyzed by the SPSS program version 21 (IBM), by describing absolute frequencies by count and relative in percentage.

RESULTS: The Chu´s gauge was applicable for the six anterior superior teeth in 1.5% of the studied population. Individually, the Chu´s gauge coincided with less than half for each type of tooth in females and males.

CONCLUSIONS: The Chu´s gauge was not compatible in 98.5% of the people in our environment. On the other hand, the Chu´s gauge probe was applied individually in less than half of the students analyzed.
