Estimation of the intercanine width, intermolar width, arch length, and arch perimeter and its comparison in 12–17-year-old children of faridabad

Abstract

Context: Dental arch morphology is an important consideration in the orthodontic treatment of dentofacial deformities. The size and shape of the arches have considerable implications in treatment planning, affecting space available, dental esthetics, and stability of dentition. The data provided by this study will be of considerable importance and relevance for practicing orthodontists and pedodontists in the region of Faridabad Aim and objective: This study aims to determine and compare the intercanine width, intermolar width, arch length, and arch perimeter in the early adolescent group (12–14 years) and middle adolescent group (15–17 years) of Faridabad. Materials and methods: Maxillary and mandibular impressions were made, study casts were prepared then the measurement of the individual intercanine widths, intermolar widths, arch length of maxillary and mandibular casts with the digital caliper, and arch perimeter with the help of brass wire was taken, obtained values were calculated, hence the results were evaluated. Statistical analysis: Data were entered into a Microsoft Excel spreadsheet. It was analyzed using Statistical Package for Social Sciences (SPSS) version 21. Graphs were prepared using Microsoft Excel. Data were normally distributed as tested using the Shapiro-Wilk W test (p value was <0.05). Inferential statistics were performed using independent Student’s t-test. The level of significance was set at 0.05. Results: In the present study, all the parameters measured were increased in males in both the age-groups, i.e., the early adolescent group (12–14 years) and the mid adolescent group (15–17 years), and a significant increase was seen in the intercanine and intermolar widths in males.
