Position of Unilateral / Bilateral Permanent Canine Impaction on the Prognosis of Treatment with KPG Index: 3D Cone Beam Computed Tomography Analysis

This study investigates the difficulty level of the impacted maxillary canines based on the KPG index of orthodontic patients. Setting and Design: This was a descriptive-analytical study. This study explained the agreement between the assessors towards the mesiodistal position of the maxillary permanent impacted canines on the treatment prognosis with the KPG index through CBCT analysis. The research sample determined CBCT images of treatment patients at the Orthodontic Specialist Polyclinic in Dental Hospital of Airlangga University who met certain criteria for the last three years since this study began and secondary data taken from patients. CBCT images from Pramita Laboratory that meet the inclusion criteria. Statistical analysis Data that had been obtained then was processed with statistical software, SPSS version 21. Statistical analysis was performed using Cohen's Kappa measuring test to determine coefficient and significance values of Cohen's Kappa Measuring Test. The coefficient value of Cohen's Kappa is 0.689. There is a difference in assessment between assessors 1 and 2 for the same case although this difference is not significant. The estimated significant value is 0.000, which indicates that the hypothesis is accepted with preconditions (sig value <0.01). Thus, it can be concluded that assessor 1 and assessor 2 have a significant similarity in the assessment of unilateral/bilateral permanent maxillary canine impacted cases. The KPG index can be used to determine the position of canine, the severity of treatment in impacted canines, and to evaluate precisely the distance of canine from the ideal position.
