Oral predisposing factors
Patients with an overjet of 6 mm or greater (Figure 1.1).
Lip incompetence (Figure 1.2).
Protruding upper anterior teeth.
Patients with residual dental disease, such as heavily restored teeth or periodontitis, are more likely to suffer greater consequences of trauma than those with otherwise intact healthy dentitions (Figure 1.3).
Unintentional traumatic dental injuries
Formulates a large cohort of dental injuries.
Patients prone to falling over due to medical conditions or those that may be at a greater risk due to seizures such as epilepsy may present multiple times throughout their lives.
Sports that involve projectile equipment such as hockey, cricket, or football are also at a greater risk. Ice hockey has been shown to have the highest prevalence of all sports.
Contact sports such as boxing and martial arts also carry an increased risk. Non‐contact sports such as gymnastics, horse riding, and athletics also represent a risk.
Socioeconomic factors
There is some evidence that shows areas with greater deprivation have a higher prevalence of trauma.
Densely populated areas also show a greater prevalence.
Human behaviour
Patients who take risks with their physical safety are at a greater risk of dental trauma (Figure 1.4).
Situations of greater interpersonal difficulty such as being bullied have a higher risk of dental trauma.
Patients who are hyperactive, such as those with Attention deficit hyperactivity disorder or ADHD, are at a greater risk of dental trauma.
Inappropriate use of teeth such as the opening of bottles or beverages also has a higher risk of dental trauma.
Learning difficulties or physical limitations
Epilepsy, cerebral palsy, learning difficulties, or hearing or visual impairment all present a greater risk of dental trauma.
Intentional traumatic dental injuries
Interpersonal violence such as physical abuse between partners or assault increases the risk of dental trauma.
Clinicians must be vigilant for signs of physical abuse and consider liaising with their local safeguarding team or seeking advice from the Police.
Iatrogenic injuries
One of the most common complications of general anaesthesia is dental trauma during intubation procedures.
Road traffic accidents
More severe traumatic dental injuries are likely in road traffic accidents. Due to the severity of other, likely life‐threatening injuries, management of dental trauma may be delayed (Figure 1.5).
Key Points
Management of risk is the key to prevention.
Those patients who have previously suffered dental trauma are more likely to have repeated episodes of dental trauma.
The patient’s social circumstances play a huge role in the risk of trauma.
Medical conditions affecting movement and proneness to falling also play a significant role.
A risk assessment should be conducted for all patients to identify those that may benefit from preventive measures.
