Abstract

The purpose of this study was to analyze luxation injuries in children between the ages of 0 and 5 years treated at an emergency service department. A total of 1,703 records, corresponding to a period of 10 years at the Emergency Center of the Baby Clinic at Londrina State University, Brazil, were analyzed. The age, gender, etiologic factors, type of injury, injured teeth, treatment and time interval between injury and treatment were determined for each patient. Of the examined records, 409 patients met the study criteria and included a total of 679 injured teeth. Statistical analyses were carried out using the chi-square test with the level of significance set at 5%. Trauma incidence was higher in boys (57.0%) and in children less than two years of age (40.3%). Falling while walking or running was the most predominant etiologic factor (37.7%), and the most prevalent type of injury was subluxation (32.6%). Luxation injuries decreased with increasing age (p = 0.045). Treatment usually occurred within the first 1-15 days and was significantly associated with the type of trauma (p = 0.041). "Monitor only" was the treatment most frequently observed (74.0%). In conclusion, more luxation injuries were found in younger children, predominantly in boys. Falls resulting from walking or running were the etiologic factor most observed, with subluxation as the most common type of trauma. Treatment usually occurred within the first 15 days after the injury. Despite the severity of these injuries, "monitor only" was the eligible treatment.

Highlights

Dental trauma is a serious public health problem among children, with most injuries constituting dental emergencies that require immediate assessment and management
Researchers unanimously agree that dental trauma to primary teeth can lead to alterations in the succedaneous dentition, especially in cases of intrusive luxation and avulsion.[3]
The purpose of this study was, to analyze primary tooth luxation injuries in children treated at the Emergency Center of the Baby Clinic at Londrina State University by investigating the age, gender, etiologic factors, type of injury, injured teeth, treatment and time interval between injury and treatment

Summary

Introduction

Dental trauma is a serious public health problem among children, with most injuries constituting dental emergencies that require immediate assessment and management. The introduction of a dental practice for toddlers and babies in the Assunção LRS, Ferelle A, Iwakura MLH, Nascimento LS, Cunha RF field of Pediatric Dentistry may contribute to a variety of new studies about trauma in the primary dentition.[2] Based on a preventive-educational philosophy, this field has created specialized centers for children between the ages of 0 and 3 years, with a special focus on dental trauma.[4] Cunha et al.[4] studied 1,654 pediatric patients at the Baby Clinic of the Araçatuba Dental School, UNESP, Brazil, and observed a 16.3% occurrence of dental trauma
