Abstract: Abstract Background Impaction of third molars is often found in dental practice. Since reported in history on the discovery of the mandible bone 13.000–15.000 BC, research on dental impaction continues to grow. In the modern population, the highest prevalence is found in the impaction of mandibular third molars. There is a limited study regarding the impact pattern of mandibular third molars.ObjectiveTo investigate the impact pattern of mandibular third molars in populations in Surabaya and the surrounding area in East Java, Indonesia. Methods A retrospective, cross-sectional study was conducted to investigate the impact patterns of mandibular third molars from the medical record data of patients at the Maxillofacial Oral Surgery Clinic of the Dental Hospital of Universitas Airlangga from July 2017-June 2019. Data were processed by age group, sex, angulation type, level position, complaint, indication was performed odontectomy and analyzed using chi-square significance of p-value ≤ 0.05. Results 1057 cases of impacted third molar teeth with a prevalence of 72%. The highest group was found aged 20–24 years (42.5%) female (60.7%), mesioangular angulation type (41.9%), level of impacted IIA impacted teeth (66.9%), local pain complaint (86.3%), and pericoronitis as an indication for odontectomy (56.3%). There is a significant difference between sex and age with angulation of impacted tooth (p < 0.05) Conclusion Impaction of mandibular third molars was found in the young age group, most characteristics in women, mesioangular angulation, level IIA position with the complaint of local pain around impacted teeth and pericoronitis as an indication of odontectomy.
