[Epidemiology and clinic of dental extractions in University Teaching Hospital Yalgado Ouedraogo, (Burkina Faso)].

Introduction: The consequences of tooth loss are often severe for the patient: aesthetic deficit, decreased masticatory coefficient, malnutrition... The objective of this study was to describe the epidemiological and clinical aspects of dental extractions of patients attending the University Teaching Hospital Yalgado Ouedraogo (UTHYO).

Patients and methods: It was a descriptive cross-sectional retrospective study on a sample of 65 patients who received a dental extraction at least in dental surgery of the UTHYO.

Results: The sample consisted of 33 (50.8%) patients female to 32 (49.2%) cases of male, or a sex ratio of 0.96. The average age was 36,55 year-old with extremes of 5 and 84 years. Employees and pupils were the most affected by extractions (33 cases; 47,8% and 22 cases; 33,8%). Dental extractions were more frequent in patients aged between 25 and 60 years. A total of 84 tooth extraction was performed in 65 patients, an average of 1.3 tooth extracted per patient. The most often extracted tooth was the third lower molar (17 cases, 22,95%). The canine was the less often extracted tooth (1 case, 1,35%). Dental decay and its complications (57 cases, 67,87%) and periodontal diseases (10 cases, 11,90%) were the commonest reasons for dental extractions.

Conclusion: Dental decay and periodontal diseases are the most important causes of dental extractions. Particular emphasis should be placed on prevention and early care of teeth.
