Abstract

Objective: This study evaluated the prevalence, clinical management and sequelae in deciduous teeth involved and permanent successors in 150 children (256 deciduous teeth. Of these, 63.3% were male, 24-35 months of age at the time of the trauma (37.9%) and the falls (78.1%) represented the major etiological factor. In relation to the type of injury, 24.6% was enamel fracture; 62.5% showed support tissue injury (lateral luxation, 22.3%). In the first and second assessments (T1 and T2), the average follow-up time was 14.5 and 26 months (256 and 131 teeth).We diagnosed clinical and radiographic sequels including discoloration of the crown (T1-15.6; T2-13.7%), inflammatory root resorption (T1-7.0; T2-8.4%); and in permanent successors, enamel hypoplasia (T1-1.2; T2-2.3%), eruption disturbances (T1-2.0; T2-1.5%).The chi-square test evidenced association, in T1, between injuries to the supporting tissues and clinical (p = 0.003) and radiographic (p = 0.004) sequelae in permanent successors; and between clinical sequelae and age at the time of trauma (p = 0.005). In T2, radiological sequelae in deciduous teeth with injuries to the tooth and supporting tissue (p = 0.035); as well as clinical sequelae with elapsed time of trauma in permanent teeth (p = 0.005). It is concluded that the follow-up of traumatized deciduous teeth is essential to prevent sequelae.

Highlights

IntroductionIn the first years of life when children start to walk and run, they become more susceptible to traumatic injuries todeciduous teeth (Cunha, Pugliesi, & Vieira, 2001; Cardoso & Rocha 2002; Jesus, Antunes, Risso, Freire, & Maia, 2010; Coutinho & Cajazeira, 2011; Assunção, Ferelle, Iwakura, Nascimento, & Cunha, 2011)
A single dental surgeon, through clinical and radiographic examination, evaluated children at two different times: time 1 (T1) and time 2 (T2), and all data were recorded in specific records
The age of the children at the time of dental trauma ranged from 1 to 6 years, the most prevalent age was 24-35 months (37.9%), male gender (63.3%); the main etiological factor was the fall from own height (78.1%) and the upper dental arch was the most affected (97.3%)

Summary

Introduction

In the first years of life when children start to walk and run, they become more susceptible to traumatic injuries todeciduous teeth (Cunha, Pugliesi, & Vieira, 2001; Cardoso & Rocha 2002; Jesus, Antunes, Risso, Freire, & Maia, 2010; Coutinho & Cajazeira, 2011; Assunção, Ferelle, Iwakura, Nascimento, & Cunha, 2011). The transmission of force after a trauma on hard tissues and pulp of the tooth and on periodontal tissues can lead to sequels in the affected teeth or permanent successors (Cardoso & Rocha, 2010). Many of the dental injuries caused by accidents are not examined early by dentists and often go unnoticed by parents and/or guardians (Osuji, 1996)
