Resumen


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. Results: Statistically signifi cant 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.
