Association of malocclusion and trauma in children: A retrospective study.

Malocclusion is considered one of the most prevalent oral issues and it is considered one of the major risk factors for dental trauma. Dental trauma is a distressing experience for children, and they can have long-term physical, esthetic, and psychological effects. Hence, the main aim of this retrospective study is to evaluate the association between dental trauma and malocclusion in children. Four hundred and fifty patients between the age of 8 and 17 years during March 1, 2020-February 31, 2021, with Ellis classes 1, 2, and 3 were included in the study. Association of type of fracture with gender and malocclusion was calculated using Chi-square test. In case of Ellis class 1 fracture, 9.1% of the patients had no malocclusion, 21.8% of them had crowding, 11% of them had spacing, and 21.8% of them had anterior protrusion. In case of Ellis class 2 fracture, 4.3% of them had no malocclusion, 6.4% of them had crowding, 2.8% of them had spacing, and 3.6% of them had anterior protrusion. In case of Ellis class 3 fracture, 2.7% of them had no malocclusion, 6.4% of them had crowding, 4.6% of them had spacing, and 4.6% had anterior protrusion. The results were not statistically significant. Children with anterior protrusion and anterior crowding are more prone to severe damage during traumatic dental injuries.
