Abstract

Objective: Description of clinical morphology, X-ray of lower wisdom teeth growing underground, classified according to Parant II at the Department of Odonto-Stomatology, Bach Mai Hospital in 2021-2022. Method: 80 patients with mandibular wisdom teeth classified according to Parant II who came to the Department of Odonto-Stomatology, Bach Mai Hospital, Hanoi from 7/2021 - 5/2022, were asked about their disease, clinical examination and Panorama x-ray. Research variables include age-gender; mandibular wisdom tooth position (RKHD); position of depth of RKHD relative to 2nd molars; RKHD correlation with jaw width. Results: The age of the patients accounted for the highest proportion in the group of patients with lower wisdom tooth extraction according to Parant II, which was the group of patients aged 18-24 years (50%) and there was no difference in gender. The rate of wisdom teeth in the lower jaw deviate to near for the highest rate up to 70%. 56.3% of the mandibular wisdom teeth according to the Parant II classification have the highest point equal to or higher than the adjacent 2nd molar chewing surface. Up to 89.3% of mandibular wisdom teeth in the study group had roots close to the lower tooth neural tube. Most of the teeth (76.3%) had no complications. Conclusion: The age of patients with the highest percentage of lower wisdom tooth extraction surgery according to Parant II is the group of patients aged 18-24 years old, regardless of gender. The lower wisdom teeth according to the Parant II classification are mainly proximal, with the highest point equal to or higher than the chewing surface of the next 2nd molar, the root is close to the lower tooth neural tube and there are no complications.
