Epidemiology of traumatic injuries to the permanent incisors of 9–12‐year‐old school children in Damascus, Syria

Abstract

This cross-sectional survey was carried out to assess epidemiological data concerning dental injuries to the permanent incisors of Syrian children. It included 1087 children aged 9 to 12 years, of both sexes, randomly selected from public and private primary schools in Damascus. The response rate was 100%. The prevalence of traumatic injuries to the permanent incisors rose from 5.2% at the age of 9 years to 11.7% at the age of 12 years (P = 0.007). The difference in prevalence between boys and girls was not statistically significant (P > 0.05). The majority (59.8%) of children who had experienced injuries to the permanent incisors reported that they were not taken to the dentist for evaluation or treatment of the damage. Among those children who had experienced traumatic injuries to the teeth 93.1% presented with untreated damage. Because some injuries were minor, such as small enamel fractures, the proportion of children who needed treatment was 63.2%. There was a tendency for children with an incisal overjet greater than 5 mm to have experienced dental injuries (P = 0.06). Children with inadequate lip coverage were more likely to have experienced dental injuries than those with adequate lip coverage (P = 0.000). The most common reported cause of injuries to the permanent incisors was violence (42.5%), followed by traffic accidents (24.1%), collisions with people or inanimate objects (16.0%) and falls (9.1%). In conclusion, traumatic dental injury may pose a serious dental public health problem.

A Prospective Study of Dentoalveolar Trauma at the Hospital Das Clínicas, São Paulo University Medical School

“…For this group and for the 31-40 year-old age group (14.1% of all cases), the most common causes of dentoalveolar traumatic injuries were traffic accidents and aggressions. It has been shown that when the survey includes former dental trauma history 10,11,14,19 , data become cumulative, which means that the older the patient, the greater the probability of trauma occurrence in his/her life, reversing the proportional ratio.…”

“…This variation may be influenced by the type of dentition (primary -30%; permanent -22%) 13 and patients' age (the frequency of dentoalveolar trauma has been shown to vary inversely proportional to age and incidences between 5.2 and 11.7% have been observed in different age groups) 14 . A great part of these studies investigated dental trauma in schoolchildren by means of clinical examinations and questionnaires.…”

Socioeconomic and clinical factors associated with traumatic dental injuries in Brazilian preschool children

“…However, previous studies with permanent teeth showed that a large proportion of enamel and dentine fractures do need treatment. [17][18][19][20] Therefore, minor damage to enamel and dentine should be assessed with caution because an injury may appear minimal at the time of the accident, but may eventually result in pulpal necrosis. 20 TDI are a result of a variety of factors.…”

Luxation de dents permanentes : incidence, réimplantation et contention par arc de Dautrey

“…C'est cette imprudence qui est à l'origine des accidents qui peuvent être domestiques ou scolaires. Marcenes et al relatent que les enfants sont les plus amenés au centre de soins pour ce genre de traumatisme, que ce soit par les parents que par les responsables scolaires [6]. La luxation des dents permanentes est également l'apanage des sujets masculins (Fig.…”

“…Le traumatisme dentaire se traduit par de nombreux types de lésions mais, sur les dents définitives, la luxation dentaire est la plus fréquente [4]. C'est un problème de santé publique en raison de son retentissement fonctionnel, esthé-tique et économique [5,6]. L'essentiel est de pouvoir réim-planter la dent définitive dans son système alvéolo-dentaire.…”
