Prevalence of traumatic injuries to the permanent incisors in candidates for orthodontic treatment

Abstract

The dental records made on presentation of 1367 consecutive patients (731 females and 636 males) for orthodontic treatment at a private orthodontic practice between 1998 and 2002 were examined for data relating to trauma to the permanent incisors. The results showed that 10.3% of these patients had suffered from dental trauma before the onset of orthodontic treatment. The highest prevalence of dental trauma was determined in the 11-15 years age group, corresponding to the dental developmental stage of the late mixed dentition. The most frequently affected teeth were the maxillary central incisors (79.6%), and the most common types of trauma were fracture of enamel-dentin without pulpal involvement (42.7%) and fracture of enamel (33.8%). Compared to patients with normal overjet and adequate lip coverage, the frequency of dental trauma was significantly higher in patients with increased overjet and adequate lip coverage (P = 0.028) or with increased overjet and inadequate lip coverage (P = 0.003). The results of the present study indicate that a significant percentage of candidates for orthodontic treatment, and especially those with increased overjet and inadequate lip coverage, suffer trauma to their permanent incisors before the onset of orthodontic treatment. It might also be concluded that preventive orthodontic treatment of such patients should be initiated and completed before the age of 11, i.e. in the early to middle mixed dentition.

Traumatic dental injuries among schoolchildren in Valencia, Spain

“…In this study the age at when the traumatism were more frequent was 8.6 years old, which is in agreement with other studies (3,5) and lower than other studies (7,8,9). Males were more affected by dental trauma (51.2%) than females (48.8%).This result was in agreement with many studies (2,4,5,8,9,14) and this may be due to the fact males tend to participate in more strenuous activities with higher trauma risk, such as contact sports and more aggressive types of playing.…”

“…Facial trauma can endanger dental health and lead to aesthetic, psychological, social and therapeutic problems (2). Traumatic injuries in permanent teeth have been reported to have a prevalence rate between 6.1% to 58.6% (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16). The great variation in reported rates can be attributed to a number of different factors, including types of study, trauma classification, methodology, study size and population, geographical location and differences in cultural behaviour (17).…”

“…Le risque de survenue de lésions dentaires liées à la pratique du sport augmente significativement chez les patients présentant une distance entre le bord libre de l'incisive centrale supérieure et la face vestibulaire de l'incisive inférieure (overjet) supérieure à 3 mm [23]. La lésion traumatique dentaire la plus fréquente est la fracture coronaire [23,24]. Quel que soit le sport pratiqué, dans 80 % des cas de traumatismes, ce sont les incisives centrales maxillaires qui sont lésées [23][24][25].…”

Relationship between Dental Trauma and Orthodontic Tooth Movement

“…Bu bulgulara göre; üst çene kesici eğimi ve overjetin azalması ile dental travmaya maruz kalma azalmakta, 6 mm'den daha fazla overjete sahip olan hastaların maksiller kesici dişlerinin travmatik bir yaralanmaya uğrama olasılığı artmaktadır. Yetersiz dudak kapamasının da kesicilere gelen travmada önemli bir predispoze faktör olduğu bilinmektedir (2,3). Bu özelliklere sahip hastalar ortodontik tedavi için aday kişilerdir.…”
