Dental trauma in primary dentition and possible outcomes on permanent successors

Objectives. The aim of this study is to determine if there is a correlation between a traumatic dental injury suffered by a deciduous tooth and the alterations that may appear in the structure of the permanent one. Materials and methods. For this narrative review, we collected articles written in English from PubMed, Scopus, and Embase. A total of 116 papers were assessed, with 20 included in the review. Results. The review found that there is a strong relationship between a traumatic incident suffered by the temporary tooth and the developmental disturbances that appear in the permanent successors. The majority of traumatic dental injuries take place around the age of 1-3 years, when the child is learning how to walk. The developmental disturbances that may appear are categorized as mild or severe, with the difference between them being the age of the child when the trauma occurred, the type of trauma, the degree of root resorption, and the force of the impact. Conclusion. The amount of injury to a primary tooth without address it when it happens has detrimental effects on the growth and emergence of permanent teeth, requiring more prolonged and costly treatment.
