DENTO-PERIODONTAL TRAUMATIC INJURIES INCIDENCE IN A CHILDREN, TEENAGERS AND YOUNG PEOPLE GROUP. A CLINICAL-STATISTICAL STUDY

Aim of the study. Considering the dental trauma is a therapeutic emergency, the aim of the study is to assess, the prevalence and factors associated withdental trauma in a group of children, adolescents and young people, using clinical-statistical criteria. Material and method. The statistical studywas performed in a group of patients aged 8-24 years, evaluating a number of 342 teeth affected by dental trauma in urban and rural areas of Iasi County, over a period of three years. Data on the studied group were analyzed using Microsoft Excel and NCSS / PASS statistical programs, with application in medical statistics. Results and discussion. Regarding the type of occlusion, a number of 90 (43.48%) patients presented unbalanced occlusions, totaling a number of 162 (47.37%) teeth, while 117 (56.52%) patients presented occlusion balanced, totaling 180 (52.63%) affected teeth. From the point of view of periodontal traumas, there were 18 (5.26%) cases of avulsion, 27 (7.89%) dislocations and 27 (7.89%) associations between 1 avulsed tooth and 1 intruded tooth. The rest of the patients had coronary or root fractures. All types of dislocations were found in male patients. Regarding the trauma mechanism in young ages with mixed dentition (8-14 years) were registered a number of 135 dental traumas caused by falling,while patients with permanent dentition (15-24 years) suffered injuries both by falling – 135 injuries (39.47%) and by hitting – 72 injuries (21.05%). Out of the total number of traumas, 23.68% affected patients with mixed dentition by injury, for the final dentition being registered the following relative frequencies: 42.11% traumas caused by injury, 18.42% traumas caused by aggression and 15.79 % by practicing a sport. Conclusions For permanent teeth, the frequency of dento-periodontal injuries has a maximum in the age period 8-10 years, the main causes of dento-periodontal injuries are due to direct or indirect blows, during games, of hard sports activities (football, basketball, hockey ), intentional or accidental blows (fist, elbow, head or blunt object), traffic accidents (bicycle, motorcycle, car). Injuries due to accidents during games are the prerogative of young people, however road traffic accidents are common in adolescent patients and over the age of 20 years.
