A 12-Year Retrospective Study of Avulsion Cases in a Public Brazilian Dental Trauma Service.

Abstract

This study assessed the epidemiological characteristics and management of the permanent teeth avulsion cases attended in a Brazilian dental trauma service from December 2005 to August 2016. A retrospective study was conducted of case records of 93 patients involving 139 avulsed teeth. Data included sex, age, trauma etiology, location of the accident, number and position of avulsed teeth, and presence and type of associated traumatic lesions. Management of the avulsed teeth was addressed as: time elapsed until teeth were retrieved from the accident's location; teeth's cleaning method and storage media; time elapsed until seeking treatment and replantation. The majority of the patients were children from 6-10 (31.2%) and 11-15 years old (26.9%). Male patients were more affected than female. Bicycle accident was the main etiological factor (31.2%). In 56 (60.2%) cases, traumatic lesions to neighboring teeth were present. In 55 (59.1%) cases, lesions to adjacent soft tissues were reported. In 82 (88.2%) cases, patients requested treatment at the same day of the accident. Sixty-four teeth (46.0%) were immediately retrieved and 28 (20.1%) were not found. Forty-two teeth (30.2%) were kept dry. Only one tooth (0.7%) was immediately replanted at the accident's site, while 51 teeth (36.7%) were not replanted. Numerous avulsed teeth were inappropriately managed and immediate replantation was not frequent. Public policies must be created to raise awareness towards the particularities of avulsion cases.

Characteristic changes of traumatic dental injuries in a teaching hospital of Wuhan under transmission control measures during the COVID‐19 epidemic

“…The male: female ratio of 1.5:1 in both periods 1 and 2 was similar to other studies. [13][14][15] Other than that, the transmission control measures during the epidemic had an influence on the epidemiology of TDIs, which included the number of patients, age, time since injury to the clinic visit, etiology, tooth location, and the type of injuries.…”

“…Patients were classified into five agegroups (0-6, 7-12, [13][14][15][16][17][18], and ≥60 years old). The time since injury to the clinic visit was classified into four groups (0-1 hour, 2-6 hours, 7-24 hours, 2-7 days, and >7 days).…”

“…26,27 The 10 m/s velocity of impact was based on previous studies in which bicycle accidents were shown to be common causes for dental trauma. 28,29 The 10 m/s impact velocity simulates a patient involved in a bicycle collision, accident or fall. 30 In this study, a 100N functional biting load was simulated for comparison with the 10 m/s impact model.…”

Awareness of Parents about the Emergency Management of Avulsed Tooth in Eastern Province and Riyadh

“…Immediate replantation of an avulsed permanent tooth is the treatment of choice and the prognosis of the avulsed tooth depends on timely intervention and storage media ( 9 , 10 ). Most of the time, parents are the first to encounter the child at the time of injury ( 11 ), so their knowledge about quick intervention and storage media is of utmost essential to decide the outcome of avulsed tooth ( 12 ).…”
