<p>The Aim of this study was to determine wheteher there are changes in the interdental arch widths and arch lengths of the madibular and maxillary arches during no-extraction and extraction orthodontic treatment. The records of 78 patients treated by one orthodontist were used for this study. Statistical data analysis included descriptive statistics of the data, analysis of the matrices, Wilcoxon Signed Rank tests and Kruskal-Wallis tests of the changes which occured during treatment. The study concluded that extraction treatment does not necessarily lead to the narrowing of the dental arches in the canine region.</p>
