Abstract
CRUZ-FLORES, Dora Denisse; IBANEZ-SEVILLA, Carmen Teresa and RUIZ-BARRUETO, Miguel Ángel. Predictive methods of the mesiodistal space of canines and premolars. Rev haban cienc méd [online]. 2023, vol.22, n.2 Epub Apr 01, 2023. ISSN 1729-519X.
Introduction:
The analysis most commonly used by orthodontists to predict the ideal space of the canine and premolars is the Tanaka-Johnston Gold Standard. However, the use of this analysis in other population groups worldwide may be questionable.
Objective:
To predict the ideal space for the eruption of the canine and premolars using the Tanaka-Johnston analysis and that of Ramos, et al.
Material and Methods:
A descriptive study was carried out using 110 pairs of study models with permanent dentition, collected during the period from 2018 to 2019. The mesiodistal widths were measured with a UBERMANN® digital vernier with an accuracy of ± 0.01 mm. Non-parametric statistics were performed on the data obtained using the Kruskal-Wallis comparison test.
Results:
The Tanaka-Johnston analysis showed a difference between the predictive and real values of -0.50 mm (±1.68) with a statistical difference of p=0.0001, and the Ramos et al. analysis was of -0.35 mm (±1.70) with a statistical difference of p=0.0001.
Conclusions:
The ideal space for the eruption of the canine and premolars was underestimated with the Tanaka-Johnston analysis and the analysis validated by Ramos, et al. However, the Ramos, et al. analysis was closer to the actual mesiodistal diameters of the canine and premolars.
