Abstract
The predictive analysis for mixed-dentition allows us to determine, even before the eruption of permanent canines and premolars, the space these teeth will need within the dental arch, thus facilitating an early diagnosis and adequate treatment planning. The aim of this study was to determine the reliability and validity of two methods that measure the mesiodistal diameters of primary teeth in the lower dental arch. The sample was formed by 80 children treated at the Pediatric Dentistry Department of the FOUNNE and whose ages range between 6 and 8. Their clinical records, dental impressions and study models were prepared. The measurements were taken in mouth (direct method) and in study models (indirect method), using drypoint compass in both cases. The results did not show significant differences, which demonstrates that both methods are equally valid and reliable.
