Overcoming the oral aspects of -self-mutilation: description of a method.

BACKGROUND/AIM: Self-injurious behavior (SIB) is a serious and chronic condition frequently seen in special needs populations, affecting 10% to 17% of individuals diagnosed with intellectual and/or developmental disabilities. A 2.5-year-old infant with SIB, whose presenting symptoms were severe tongue and lip lacerations accompanied by much hemorrhage, is presented here to illustrate the problem and to show how this may be prevented. MATERIALS AND METHODS: An appliance is described which effectively limits the damage caused by SIB and permits rapid healing of existing injuries. RESULTS: The method provides for a stable, retentive, and comfortable device on the infant's undererupted and largely nonretentive crowns of the deciduous teeth as well as for all permanent teeth in children, adolescents, and adults. CONCLUSIONS: The appliance has been successfully employed for the past 10 years in patients with SIB who have attended for treatment in the Special Needs Clinic in our Department.

A brain abscess of probable odontogenic origin in a child with cyanotic heart disease.

The purpose of the present report was to present a rare case of a brain abscess in a child with heterotaxy syndrome, severe cardiac anomalies, and extensive dental caries. The pathogen was Streptococcus intermedius isolated from the cerebrospinal fluid. The source of the pathogen was probably an infection of a primary molar with a dentoalveolar abscess involving the bud of the permanent successor. After a long course of antibiotic regimens followed by a craniotomy with abscess drainage, a shunt, and comprehensive dental treatment, the patient was discharged from the hospital without any neurological sequel. At home, she completed an additional 3 months of oral antibiotics. This is the only known documented case of a toddler with a brain abscess of probable odontogenic origin without previous dental intervention. It emphasizes the importance of collaboration between cardiologists and pediatric dentists, especially in referring children with congenital heart defects for early dental checkups.

Neurosensory changes in the infraorbital nerve following zygomatic fractures.

OBJECTIVE: To document the neurosensory changes in the infraorbital nerve following zygomatic fractures managed in various ways. STUDY DESIGN: Twenty-five patients were included in the study. Neurosensory function was assessed with calibrated nylon monofilaments, electrical stimulation, heat detection thresholds and response to pin prick in the infraorbital, supraorbital, and mental nerve regions. Patients were seen immediately post-trauma, then 1 and 6 months following surgery. RESULTS: Nine fractures were caused by traffic accidents (TAs), 8 by falls, and 8 by a local blow in a physical dispute. The fractures consisted of 15 displaced and 10 minimally or nondisplaced zygomatic complex fractures, and were left surgically untreated in 7 cases (None group), reduced but not fixed in 8 cases (Reduction group), and fixed with plates in 10 cases (Plates group). Plates were employed significantly more often in displaced fractures (chi-squared P = .0006). At 6 months significantly improved infraorbital nerve function was found in the Plate and None groups relative to the Reduction group (ANOVA P = .006). Only 1 case of chronic neuropathic pain was found. CONCLUSIONS: This study concurs with previous studies in finding that plate fixation allows for significantly better restoration of infraorbital nerve function. Chronic neuropathic pain following zygomatic fractures is rare.
