Abstract

GUTIERREZ ROJO, Jaime Fabián; DELGADO SANDOVAL, Damaris; MENDOZA MINJAREZ, Alhelí  and  ROJAS GARCIA, Alma Rosa. Gender-adjustment of Moyers dentition analysis for the Nayarit (Mexico) population. Rev. Odont. Mex [online]. 2015, vol.19, n.4, pp.228-231. ISSN 1870-199X.  https://doi.org/10.1016/j.rodmex.2015.10.003.

Moyers percentile tables are one of the diagnostic elements used for early age malocclusions. These tables predict the size of non erupted canines and premolars.

Material and methods:

The sample was composed of 180 male patients study models and 319 female patients study models used for orthodontic pre-treatment. Models met inclusion criteria. So as to match samples, 180 female study models were randomly selected. Descriptive statistics were calculated, percentiles 75 and 50 for each gender, t Student test was used to compare results of tables with adjustment of percentiles 75 and 50 for each gender with Moyers tables results and values of the study models.

Result:

Statistically significant differences were found when comparing Moyers’ tables results with those of the Nayarit population. Percentile 75 of Nayarit tables over-estimated values of canines and premolars in both genders. No statistical differences were found with 50 percentile.

Conclusions:

It is recommended to use the 50 percentile of the conducted adjustment in order to predict size of canines and premolars.

Keywords : Moyers; mixed dentition analysis.
