Physical abuse may result in numerous types of injuries including contusions, ecchymosis, abrasions, lacerations, fractures, burns, bites, hematomas, retinal hemorrhaging, and dental trauma. Head and orofacial injuries for which dentists should be alert include:

• Head Injuries^8-10

  • Scalp and hair – subdural hematomas (cause more serious injuries and deaths than any other form of abuse), traumatic alopecia, subgaleal hematomas, and bruises behind the ears

  • Eyes – retinal hemorrhage, ptosis, and periorbital bruising

  • Ears – bruising of the auricle and tympanic membrane damage

  • Nose – nasal fractures or an injury resulting in clotted nostrils

• Orofacial Injuries^9,11,12

  • Lips – lacerations, burns, abrasions, or bruising

  • Mouth – labial or lingual frenum tears (characteristic of more severely abused children), burns, ecchymosis or lacerations of the gingiva, tongue, palate, or floor of the mouth

  • Maxilla or mandible – past or present fractures to facial bones, condyles, ramus, or symphysis of mandible. Malocclusion or temporomandibular joint limitations may be a result of this type of injury

• Bite marks

  • Many times misdiagnosed as simple childhood bruises but often associated with physical or sexual abuse

  • Typically oval or circular configuration

  • A central area of hemorrhage, may be found between markings of the upper and lower dental arches, suggesting physical or sexual abuse

  • Although marks may occur anywhere on a child’s body, the most common sites are the cheeks, back, sides, arms, buttocks, and genitalia

  • In addition to making a mandated report in a case where bite marks are indicative of abuse, the general dentist should include a recommendation for further evaluation by a forensic pathologist or odontologist in the treatment recommendations and referrals^13,14
