ABSTRACT
PURPOSE: The purpose of this study was to investigate whether the application of mixed dentition analyses in cleft lip and palate patients differed from noncleft patients and to investigate which method provided the most accurate prediction in cleft lip and palate patients. METHODS: Study casts of 30 cleft lip and palate patients and 30 noncleft patients were used in this study. Each patient had dental casts at two stages of dental development. The methods compared included the Moyers, the Tanaka & Johnston (T/J) and the Boston University (BU) prediction methods. RESULTS: Analyses for both groups indicated that the predicted values yielded by each method were significantly different from one another but were all significantly correlated with actual tooth size. Moyers 50% and BU had the smallest mean difference values and no significant difference between the predicted and actual values for both cleft and noncleft control groups. CONCLUSIONS: Types of cleft had no effect on the size of the mandibular permanent canines and premolars. The application of mixed dentition analyses in cleft lip and palate patients does not differ from noncleft patients. Both Moyers 50% and the BU method have high accuracy and correlation in prediction of unerupted teeth in both groups.

Inaccuracies exist in identifying and recording various types of oral cleft. One of the major reasons for this problem is that no efficient or universally accepted recording system presently exists. The RPL system introduced in this article provides an accurate and systematic numerical recording for the identification of various types of lip and maxillary clefts. The simplicity of the system allows quick and efficient data storage and retrieval.
