Introduction: Dento-maxillary trauma is damage to the complex made up of the teeth and their underlying bone support tissues during any physical and sporting activity of everyday life. These traumas are frequent during the practice of combat sports with an incidence unknown in our context. The aim of this study was to determine the epidemiological and clinical profile of these traumas in the practice of combat sports in Yaoundé.

Materials and Methods: We carried out a descriptive and prospective cross-sectional study over a period of three months, from January to March 2020. All the combat sports practitioners were included.

Results: During the study period, 56 on 380 licensees presented a dento-maxillary trauma in combat sports practice giving a prevalence of 14.74%. The average age of the victims was 24 years old with 80.35% of men. Soft tissue wounds (37.5%) and coronary fractures (32.14%) were the most common injuries. Karate was the most traumatic with 33.93% of injuries followed by boxing (25%). The majority of accidents were caused by kicking and punching (83.93%). Licensees with 8 years or more in seniority were the most victims with 48.21% of cases. The anterior teeth were the most injured. Among the victims, 26.78% did not wear mouthguards and 53.33% of them motivated the lack of financial means as reason.

Conclusion: Dento-maxillary trauma are not frequent among combat sports practitioners in Yaoundé. Karate and boxing are the most dento-maxillary trauma, especially during training. Faced to these risks, it is necessary to pay particular attention to these sports in order to make combatants aware of the measures to be taken in the prevention of injuries.
