Aim: To analyze the effectiveness of traditional treatment options for impacted mandibular canines in adolescents and young people while considering age, the number of impacted teeth, type of treatment, and orthodontic appliances. Materials and Methods: The retrospective investigation of the data of the case histories of patients with impacted mandibular canines was done: 53 cases in children and adolescents (Q1-Q3 = 13 to 15 years) (Group І) and 19 in young adults (Q1-Q3 = 21.25 to 33.5 years) (Group ІІ). The anamnesis data and clinical examination, x-ray findings, jaw model findings, treatment methods, and results were studied. Results: In Gr. I, unilateral impaction prevailed (71.7%), whereas 20.8% of patients had bilateral impaction of mandibular canines. In Gr. II, 57.9% of patients had unilateral impaction, whereas 26.3% had bilateral impaction of mandibular canines. There is a strong correlation between the treatment outcomes and the patient’s age, the number of impacted teeth, and the type of orthodontic appliance. Conclusions: The findings indicate the risk of poor treatment effect increases with the patient’s age and the kind of appliances. the number of retained teeth, and their location in the jaw.
