VALIDATION OF KPG INDEX “CLASSIFICATION METHOD TO PREDICT ORTHODONTIC TREATMENT DIFFICULTY LEVEL OF IMPACTED CANINES”

Objective: To determine the position of impacted canine in 3 dimensions and estimate difficulty treatment using 3D “KPG index”, a new classification method.
 Study Design: Cross sectional analytical study.
 Place Duration Study: Orthodontic Department, Rehman College Dentistry, Peshawar, from Aug to Oct 2020.
 Methodology: cone beam computed tomography (CBCT) scans 43 subjects with 47 canines were obtained. Using KPG index, 6 measurements taken for each tooth three planes. The scores later summed up. Based on cumulative scores, impaction was classified into categories Easy (0–7), Moderate (8–14), Difficult (15–19), Extremely (20+). Comparison Gender index also performed.
 Results: Impacted found be left palatal side female predilection. Canines scored mostly moderate category. Highest percentage Sector II, followed by sector III IV. Comparing maxillary right sides (p=0.087), buccal or (p=0.545), males females (p=0.279), in-statistically significant difference found.
 Conclusion: imaging has allowed us precisely locate sagittal, coronal axial Hence, dictated our anticipated treatment.
