Abstract

Objectives: To describe the radiographic characteristics of lower wisdom teeth in adults at Vietnam-Cuba Friendship Hospital, Hanoi, in 2024. Method: 72 patients with lower wisdom teeth who visited the Department of Dentistry, Vietnam-Cuba Friendship Hospital, Hanoi, were interviewed, clinically examined, and underwent panoramic X-ray imaging. The study variables included age, gender, the position of lower wisdom teeth (LWT), the depth of LWT to the second molar, the correlation of LWT with the width of the jawbone, shape, and the number of roots of LWT. Results: The average age of the patients was 30.65 ± 10.63, with no significant difference in gender. Most LWTs were in the mesial angulation, accounting for 53.33%. The distance from the distal side of tooth 7 to the anterior border of the ascending ramus was smaller than the mesiodistal size of the crown of tooth 8, which was the most common, at 55.83%. The highest point of the crown of tooth 8 was equal to or higher than the occlusal surface of tooth 7, which occurred most frequently, at 73.33%. The root shape of tooth 8 was mostly curved (39.16%), and 84.17% of teeth had two roots. Conclusion: The average age of patients was 30.65 ± 10.63, with a higher proportion of females than males. This study found LWTs most commonly found in a mesial position, with type A depth and type II jawbone width. The majority of LWTs had two roots, with curved roots being predominant.
