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 L�ndstrom that includes the first permanent molars and used digital calipers. The results showed L�ndstrom method to be more reliable, reproducible and less time consuming.
