A retrospective study of 889 injured permanent teeth

Abstract

The aim of this study was to investigate pre-injury factors, causes of dental injuries and healing complications after traumatic injuries to permanent teeth. The analysed sample comprised 889 permanent teeth of 384 patients, who were treated in the Dentistry Department in Faculty Hospital in Pilsen. Enamel-dentin fractures [233 teeth (26.2%)] and lateral luxations [207 teeth (23.3%)] were the most frequent injuries. The age of the patients at the time of injury varied between 7 and 65 years. Predominantly, children were affected [587 injured teeth (66.0%)]. The most frequent causes of injuries in patients older than 11 years were various sport activities, predominantly bicycling. Pulp necrosis was observed in 239 teeth (26.9%). It was the most frequent post-traumatic complication in all types of dental traumas. Teeth with a completed root formation demonstrated a higher prevalence of pulp necrosis than teeth with an incomplete root formation in all types of luxation injuries. External root resorption was observed in 144 teeth. The rate of inflammatory resorption differed between the various types of luxation injuries (extrusive luxation 5.6%, lateral luxation 11.6%, intrusive luxation 33.3%). Following avulsion and replantation, active inflammatory resorptions were diagnosed in 13 (26.5%) of 49 replanted teeth and ankylosis/replacement resorptions were observed in 21 (42.9%) of 49 replanted teeth. After avulsion, primarily, immature teeth were affected by these complications. Within the observation period of 5 years, 39 teeth (4.4%) had to be removed (16 teeth with root fractures, 19 avulsed and replanted teeth, 3 luxated teeth, 1 tooth with crown-root fracture).

Intracanal dressing paste composed by calcium hydroxide, chlorhexidine and zinc oxide for the treatment of immature and mature traumatized teeth

“…Immature teeth present a wide open apex that may favor revascularization and repair of the vascular bundle after trauma. In these teeth the frequency of pulp necrosis is lower (13.6%) than in teeth completely closed roots (63.1%) 3 . Despite the more favorable prognosis for immature teeth, the need for endodontic therapy may be a challenge to conventional endodontic treatment.…”

“…Literature reports have shown that intrusive luxation and tooth avulsion are most frequently related to pulp necrosis and root resorptions (76.2%), requiring endodontic treatment 3 . In the present study this relationship was also observed for completely developed teeth, since most of the sample presented intrusive luxation (40.8%).…”

“…Depending on the intensity and type of injury, damage may be reversible or present an unfavorable prognosis for these tissues 2 . Among the dental trauma complications, the most common are pulp necrosis and microbial infection, which may accelerate the root resorption process [2][3] . In order to minimize these complications, endodontic treatment should be performed at an appropriate time to reduce infective and irritant agents.…”

Replantation of avulsed teeth using the 180-degree rotation method and a vacuum-formed splint in mixed dentition: a case report

“…Tooth avulsion is relatively common in children and the maxillary anterior teeth are most frequently affected (1). In case of permanent tooth avulsion, replantation of the avulsed teeth is recommended from functional and aesthetic view points (2).…”

“…Los traumatismos más frecuentes en los dientes, según estudios reportados, fueron: fractura coronal no complicada (54,2%) y luxación lateral (22,7%) en el estudio realizado en la Clínica CES de Medellín [9]; subluxación (21,46%), avulsión (17,18%), luxación lateral (16,66%) en Brasil [2], y fractura no complicada de corona (26,2%) y luxación lateral (23,3%) en un estudio en Republica Checa [18].…”
