Evaluation of dental crowding in mixes dentition comparison between two methods

Abstract

Assessment of dental crowding in mixed dentition from sixty-two study models, maxillary and mandibular, by two different methods was attempted. A single examiner compared the following methods: Nance that used brass wire for measuring the available space between the mesial surfaces of the first permanent molars and Lündstrom that includes the first permanent molars and used digital calipers. The results showed Lündstrom method to be more reliable, reproducible and less time consuming.
