Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2017, Vol 2, Issue 6
Abstract
This retrospective study was to examine the dental arch width changes of extraction and non-extraction treatment in Class I patients. The study was performed on pre-treatment and post-treatment dental casts of 70 patients (35 extractions and 35 non-extractions).The study models are taken pre-treatment and post-treatment. The inter-canine and inter-molar arch width measurements were measured using a digital caliper. Paired samples t-test, ANOVA, post HOC test was used to evaluate the treatment changes within each group. To compare the changes between groups, independent samples t-test was performed. There is significant difference in inter-canine width as compared to inter-molar width in extraction cases while there was no significant difference in non-extraction cases. While, an overall increase in inter -molar distance and inter-canine distance of mandibular arch and decrease in maxillary inter-canine distance in non-extraction cases.
