The ability of hand-eye coordination with indirect vision (CMOVI) is essential in dental practice, since it depends on visual access to maneuver in remote regions of the mouth without compromising ergonomic principles. The objective of this research is to establish if the DIVIN and TrazaCav devices are useful to identify this coordination in applicants to enter the Dentist Surgeon (MDC) program of the Academic Unit of Dentistry of the UAZ (UAO / UAZ). For this, an experimental cross-sectional study was carried out in a stratified random sample (n = 169) of aspiring UAO / UAZ, promotions 2014 to 2016. Each subject executed three CMOVI exercises, using the DIVIN and the TrazaCav, considering three categories: precision in profiling, depth in the layout and time spent, evaluated by three experts. The results, concentrated in the registration card, were subjected to description of frequencies and measures of central tendency. The results were: 19 students located in general average of 6.0 (on a base of 10), 16 in 5.3, 15 in 5.7 and 14 in 7.0, the rest is distributed without a uniform pattern in the remaining possibilities. In precision in profiling, 34 obtained 1.7 of qualification (on a base of 4.0), 32 with 2.0 and 24 with 2.3. In depth in layout, 31 are located in 2.3 rating (on a 4.0 basis), 27 in 2.7 and 25 in 2.0. In time employed, 116 are grouped into 2.0 rating (on a 2.0 basis), 28 in 1.0 and 10 in 1.7. The ratings are similar in each edition, with a greater difference in 2015, with a slight increase in accuracy and depth. In conclusion, the usefulness of the DIVIN and TrazaCav to identify the CMOVI in aspiring DCM is evident, given the constants found in each one of the editions of the preparatory course of this institution.
