Crown-Root Fractures in Primary Teeth: A Case Series Study of 28 Cases

Abstract

Crown-root fractures in primary teeth are rare, with a wide variation of patterns that make diagnosis and treatment difficult. The aim of this study was to present a case series of crown-root fractures in primary teeth of children who attended a reference center. The study followed 28 cases of crown-root fractures in 26 children, representing 4% of the total number of attendees over 11 years of reference service at the Universidade Federal de Pelotas, Pelotas, Brazil. In most cases, the maxillary central incisors (85.7%) were involved. In the crown, 57.1% of the cases had a simple line of fracture, and 42.9% had multiple lines. Simple lines predominated in the root (89.3%). In cases with simple fracture lines in the crown, 37.6% underwent a total extraction, 31.2% required a partial extraction and 31.2% underwent pulpectomy. In most teeth with multiple lines of fractures in the crown, total extraction was performed (91.7%) All cases were followed-up until the eruption of the permanent successor tooth, and all patients had favorable outcomes.

Evaluation of knowledge among general dentists in treatment of traumatic injuries in primary teeth: A cross-sectional questionnaire study

“…looked into the clinical and radiographic sequelae of traumatized primary teeth and concluded that the crown-root fracture was the common type of fracture and presented with higher clinical sequelae. [10] Only 36% of dentists answered correctly, indicating that, the knowledge regarding the crown and root fractures remains unsatisfactory.…”

“…had reported that subluxation was one of the common types of luxation injuries from his series of case reports. [10] AAPD suggested different treatment options depending on the degree of displacement. [11] Assunção et al .…”

“…[8] However, only a few sporadic case reports have been published on the management of traumatic injuries in primary teeth, and only a few suggests the positive treatment outcome in primary dentition. [910]…”

Dental trauma with intrusive luxation and six-year monitoring: clinical case report

“…Costa et al 13 emphasize the importance of regular monitoring for complications, including possible late sequela. In their study, it was detected that the clinical conditions and the X-ray characteristics influenced the executed treatment.…”

Knowledge Among General Dental Practitioner in the Treatment of Traumatic Injuries in Primary Teeth – A Questionnaire Study.

“…6 The selected dental population had a minimal knowledge regarding management of fractured tooth with displaced fragments essentially involving root fracture. 7 Avulsion is more common in primary teeth due to the resilient alveolar bone and the prevalence has been reported to be 5.8%. A few case reports have suggested the success and failure of replacement of avulsed teeth.…”
