Traumatic injury to maxillary incisor teeth in a group of South Wales school children

Abstract

This study examines, from photographic records, the prevalence of accidental damage to maxillary incisor teeth in a group of 968 11/12-year-old South Wales school-children; 15.3% showed evidence of trauma ranging from enamel fractures or discolouration to actual loss of a tooth. Boys (19.4%) showed a higher prevalence of trauma than girls (11%). Maxillary central incisors were the most at risk from trauma, with coronal fractures being the most commonly sustained injury. Those subjects who showed evidence of trauma had an statistically (p less than 0.001) but not clinically significantly greater overjet than did those who had none. The percentage of subjects suffering trauma increased significantly with increasing overjet, but lip incompetence did not affect the prevalence of accidental damage. Though statistically unsupported due to the small numbers involved in this cohort, it appeared that the rougher nature of boys activities and their more active participation in sports were of greater importance than the magnitude of their overjet in determining whether their teeth were at risk from trauma. In contrast, it was the magnitude of the overjet which was the dominant factor in girls. Despite the wide availability of relatively simple means of restoration and, in the majority of cases, regular dental examinations, only 14.8% of traumatised teeth had received treatment at this age.

Analysis of Traumatic Injury in 886 Permanent Anterior Teeth

“…Discussion 1. In this study, 339 of the 512 children with dental trauma were boys and 173 were girls, the boy-to-girl ratio was 1.96:1, which is consistent with the ratio of 1.76:1 reported by Hunter 1,2) . The…”

Retrospective analysis of pulp necrosis frequency after uncomplicated crown-fractures in children

“…Veliki procenat povređenih maksilarnih centralnih inciziva takođe odgovara nalazima drugih istraživača. Ovi zubi mogu biti u protruzionom položaju i često neadekvatno pokriveni gornjom usnom što bi omogućilo amortizaciju udara [17,18]. Osim toga,za razliku od mandibule koja je pokretna, maksila je rigidna što dodatno doprinosi predispoziciji za nastanak povreda [17,18].…”

Prevalence of dental trauma of permanent anterior teeth in children visiting College of Dentistry/Hawler Medical University

“…The maxillary central incisors are sometimes in a protrusive position and often inadequately covered by the upper lips, which could possibly amortize the strike. 28,29 Unlike the lower teeth and the canines, the latter, considered as the strongest teeth in the jaw, are usually better protected by the lips and not so prone to injury. [28][29][30][31] Moreover, the upper jaw is rigid and the lower jaw is movable, which additionally contributes to the predisposition of certain teeth to injury.…”
