Effect of luxation injuries on permanent teeth

Abstract Trauma to the supporting tissues of the teeth are among the most common dental injuries, leading to such complications as pulp canal obliteration, necrosis and root resorption. The aim of this investigation was to study the outcome for young permanent teeth subjected to luxation injuries. From 108 dental records 171 teeth with injuries to the supporting tissue were selected. The material comprised 130 subluxated, 15 extruded, 9 intruded, 15 exarticulated and 6 laterally luxated teeth in children aged 6–19 years. Apart from luxation, 59 teeth (35%) had additional crown and root fractures. 65% of the teeth recovered without complications. 78% of the subluxated teeth and 24% of the luxated teeth showed uneventful posttraumatic healing. Concomitant uncomplicated crown fractures or root fractures without displacement of the coronal fragment did not interfere with the healing. Of 60 teeth with healing complications, 52 (87%) were subsequently recorded as healed, the remaining 8 were extracted or had progressive root resorption. Loss of pulp vitality and external root resorptions were the most often recorded complications (28% and 17% of the total material respectively). Pulp canal obliteration was noted in 3% of the cases. Extent of injury and degree of tooth maturity were found to be related to healing compliations.

Luxation injuries to permanent teeth -- a retrospective study of etiological factors

Trauma to permanent teeth with luxation injuries often leads to clinical treatment problems. Traumatic injury patients in local clinics are often limited in number. The aim of this investigation was to retrospectively study the etiological factors in luxation injuries to permanent teeth in relation to sex, age, time of year and diagnosis. A total of 108 files from patients, aged 6 to 19 years, with 196 teeth with luxation injuries, were collected. The maxillary central incisors represented 70% of all teeth injured and 70% of the teeth belonged to children between 8 and 12 years of age. Falls (34%) and bicycle-riding (30%) were the most frequent reasons for trauma, followed by sports (14%) and assaults (13%). Boys were more often involved in trauma. Girls were as often involved in sports accidents as boys. Subluxation was the most frequent diagnosis (77%), followed by extrusion, intrusion, exarticulation and lateral luxation. Accidents were reported most frequently during spring and early summer. A slight increase was also noted during autumn.
