Studi Radiografi Impaksi Gigi Molar Ketiga Rahang Bawah Menurut Klasifikasi Winter dan Quek di RSGMP Universitas Jember

Abstract

Introduction: Tooth impaction refers to the failure of a tooth to erupt, either partially or completely. The mandibular third molar is the most commonly impacted tooth compared to other permanent teeth. This study aims to analyze the distribution of impacted mandibular third molars based on Winter and Quek Classifications among patients at the Dental and Oral Hospital of Jember University using panoramic radiography. Methods: This observational analytic study involved 74 samples (total sampling) selected based on inclusion and exclusion criteria. Variables examined included mandibular third molar impaction classified according to Winter and Quek Classifications, gender, and region. The data were analyzed using the Chi-square test (p=0.05). Results: Impacted mandibular third molars from May 2022 to May 2024 at the Radiology Unit of the Dental and Oral Hospital, Jember University, were more prevalent in female patients (67.57%) compared to male patients (33.78%). Impaction in region 48 (42.57%) was slightly higher than in region 38 (41.89%). Bilateral impactions (68.92%) were more common than unilateral ones. Impactions classified as mesioangular, vertical, and distoangular were more frequently observed in females, whereas horizontal and inverted classifications were more common in males. In region 48, mesioangular and distoangular impactions were more prevalent compared to region 38, whereas vertical, horizontal, and inverted classifications were more frequently found in region 38 compared to region 48. Conclusion: Cases of impacted mandibular third molars at the Radiology Unit of the Dental and Oral Hospital, Jember University, from May 2022 to May 2024, based on 74 panoramic radiographs, were predominantly observed in female patients and were most common in the 20–30-year age group. Among both males and females, the mesioangular classification was the most frequently occurring type in both region 38 and region 48.
