Characteristics of avulsed permanent teeth treated at Beijing Stomatological Hospital

Prevention of dental injury is considered to be more important than its treatment. A study was established to reduce the prevalence and the complications of tooth avulsion.

The aim of this study was to investigate the characteristics of tooth avulsion of permanent teeth among patients that visited the Emergency Department of Beijing Stomatological Hospital in China.

A retrospective analysis was performed of the dental records of 88 patients with 120 avulsed permanent teeth between 7 and 75 years old who had attended the Emergency Department of Beijing Stomatological Hospital in China during the period 1 July 2008 until 30 June 2009.

In 88 examined patients, the number of avulsed permanent teeth was 120. In 63 (71.6%) patients, in total 85 avulsed teeth were treated with replantation. In 18 (28.6%) patients, the avulsed teeth were stored in dry media. In only eight cases (12.7%), the avulsed teeth were replanted within 30 min. In approximately half of the cases (49.2%), the replanted teeth were fixed with stainless steel splint and a composite resin.

It was evident from this study that there were delayed tooth replantations in many tooth avulsion cases. Thus, educational programs should be conducted to create awareness about the importance of immediate replantation, which will entail better prognosis of traumatic avulsed permanent tooth.
