Applicability of Moyers’ Prediction Table in Orthodontic Patients Reporting to KCD Peshawar Population

Abstract

Objectives: The aim behind this research, is to determine the applicability of Moyers’ table in Peshawar population.
Materials and Methods: A total 100 patients’ casts how had complete details in their files, who were Pakistani nationals, having complete set of permanent teeth upto 1st molar, no proximal restorations and caries were included. Patients having dental
anomalies, previous orthodontic treatment, craniomandibular dysfunctions, attritions of teeth and Syndromes were excluded.
The mesiodistal widths of the maxillary and mandibular permanent incisors, canines, first and second premolars were measured using digital calipers. The predicted total, of the mesiodistal diameters of the canines and premolars, was evaluated from the Moyers tables at 75%. Pearson's correlation test was applied, to determine the relationship between the total sum of the actual
width of the canines and premolars and the sum of the predicted width of the canines and premolars from the Moyers table.
Analysis was performed by SPSS version 20.0.
Results: Most of participants were females 63(63%) as compared to males 37(37%). In maxilla the mean actual (23.76mm) and
predicted mesiodistal width(22.76mm) of cupids and bicuspids were close to each other. But the correlation between actual and predicted mesiodistal width of cupids and bicuspids in maxilla was weak. It was weak in female (r=0.156). In mandible for male the   correlation was positive as well (r=0.8130) but it was weak for females (r=0.334). moderate correlation was found for overall .
Conclusion: Moyer's prediction table is not a very precise method for estimating tooth dimensions in a Peshawar-based sample.
