The authors compared arch width measurements of diagnostic dental models obtained from dental school patients. Arch width measurements were taken in the canine area on each dental cast in an effort to assist forensic dental investigators in matching certain classes of subjects to the bites they might possibly inflict. If any canine teeth were absent, the measurements were taken using other specified adjacent teeth which the investigators felt would be interpreted as the arch width determiners in a bite mark injury. The ages of the subjects varied from 14 to 87 years. Statistical comparison of the maxillary arch width, mandibular arch width, and the mean difference between maxillary and mandibular arch width were performed. Significant differences between the arch width measurements were found to exist between several classes of subjects based on race and sex.
Fragments recovered from the burned wreckage of a gasoline truck and thought to be parts of teeth were confirmed as such after they were examined with a scanning electron microscope. The appearance of the fragments was compared with previously published descriptions of teeth which had been incinerated under laboratory conditions and also examined by scanning electron microscopy.
Pan American Flight 759 crashed on takeoff from New Orleans International Airport on 9 July 1982. One-hundred-and-fifty-four persons lost their lives making this the second worst air crash in the United States. A dental identification team was assembled and began working the next morning. Ninety-three victims were positively identified by dental means and twenty-three other victims had strong supporting dental evidence as to their identities. The organization, method used, planning, and problem resolution concerning the dental team for this crash are presented.
The maxillary sinus mucocele occupying the entire sinus is rarely reported by dentists. This article discusses one such case diagnosed as an exceptionally large maxillary sinus cyst occupying the whole sinus. Unlike their findings in the medical literature, the authors were unable to find many similar cases reported in the dental literature. The location of these mucoceles necessitates the use of diagnostic radiographs, especially those of the panoramic type. Because etiology is still not fully understood after almost 100 years, the authors suggest and discuss four possible mechanisms of sinus mucocele formation and growth.

When dental services and appropriate use of restraints are used for persons who are severely and profoundly mentally retarded and developmentally disabled (MRDD), oral health is enhanced and dental neglect is controlled or even reduced. This paper defines dental neglect and examines the consequences to persons who are MRDD when appropriate restraints and preventive dental home care are not used. Oral health outcome assessment data of this MRDD population indicate the presence or absence of dental neglect. The outcome assessment measures the level of oral health within the developmental center. The Louisiana Department of Health and Hospitals (DHH) operates nine developmental centers, where approximately 2000 individuals with severe to profound mental handicaps reside. Two-thirds (66%) of this population are resistive to the delivery of clinical and preventive dental services. The responsibilities and roles of dental health professionals, long-term-care facility administrators, and direct service staff are discussed to help reduce dental neglect in these centers. For these individuals to receive quality and comprehensive dental care, appropriate use of restraint/physical hold is necessary. The Dental Health Resource Program (DHRP) developed guidelines for delivering preventive and clinical dental services to reduce confusion and misinterpretation of the definition and use of restraint in the Louisiana Developmental Centers (LADCs).
