DENTAL TRAUMATOLOGY

n DENTAL TRAUMATOLOGY à Branch of dentistry¨Epidemiology¨Etiology¨Prevention¨Assessment¨Diagnosis¨Management of trauma to the jaw and

surrounding tissues

nDENTAL TRAUMA¨Simple¨Complex à management may be

interdiciplinary or multidiciplinary

n Traumatic injuries are typically quick, sudden, and unexpectedà Clinicians must be prepared to render appropriate emergency care any time

TRAUMAn NON INTENTIONAL INJURY:

¨Domestic, recreational, sport, work, vehicular related injury (are not inflicted on purpose by one’s self or another person

n INTENTIONAL INJURY :¨Suicide, homicide, domestic abuse, war,

terrorism and other such injuries that are purpose fully inflicted

n There are basiccaly 2 types of injuries to dentition :¨Hard tissue injuries :

nTeeth, alveolar bone, and other facial bones.

¨Soft tissues injuries :nFacial skin, lips, mucosa (cheeks

and periodontium) soft tissues of the hard ad soft palate, and tongue.
