Abstract

Background: Describe the clinical characteristics, X-ray of Lower third molar according to Pell, Gregory classification of patients who came for examination and treatment at Cai Nuoc General Hospital. Materials and methods: Descriptive study, clinical intervention Patients with deviated, proximal lower wisdom teeth with indications for surgery were evaluated through clinical examination and panoramic X-ray film with The characteristic of the angle measure by the straight line passing through lower third molar and the adjacent second molar axis (determined between the occlusal surface and the root cleft) ranges from 10⁰ to 90 ⁰ (classified according to Winter's tooth axis). Adjacent teeth are not lost, do not have large breaks, do not have large fillings and do not wear orthodontic appliances… - The overall health is sufficient to respond to surgery and laboratory tests within normal limits to allow progress. surgery. Results:  Study on 99 cases lower third molar of treated surgically at Cai Nuoc General Hospital - Ca Mau - 90.9% of Lower third molar are present in the mouth.  - Teeth 38 accounted for 55.6% and 48 accounted for 44.4%. - Teeth in position II accounted for 92.9% and position B was 83.8%. - Teeth in the study had an average difficulty of extraction accounting for 77.8%. - Teeth related to the lower canal on radiographs accounted for 30.3%. Conclusion: Diversity in position, shape, size, often stuck between teeth 7 and branches up to the lower jaw bone or deep in the bone, abnormal roots in number and morphology greatly affect the methods and techniques of lower third molar extraction.
