ABSTRACT
Identification of spirochetes in dental plaque is difficult. Not all spirochetes can be cultured and microscopic analysis based on darkfield or phase optics cannot determine the genus and species of individual bacterial cells. The purpose of this study was to use monoclonal antibodies in an immunoenzyme technique to stain spirochetes in dental plaque. Separate mAb were used to estimate total spirochetes and relative numbers of 2 distinct types of Treponema denticola. Plaque samples were collected from 40 subjects grouped by age. Results showed that older subjects are more likely to have spirochetes, to have more spirochetes and to have more diverse populations or spirochetes than younger subjects. Our studies suggest that T. denticola may be the first treponeme to colonize the primary dentition, that T. denticola appears to comprise a major proportion of all spirochetes at all ages and that two distinct serotypes of T. denticola are found to coexist in plaque from most children.

The purpose of this investigation was to determine the type and prevalence of dental injuries seen in a hospital emergency room. Of the 10,436 patients who were treated at the hospital emergency room as a result of a traumatic episode, 765 (7.3%) had sustained injuries to structures of the oral cavity. The leading cause of dental injury was falls, accounting for 55.8% of the injuries. The male-to-female ratio of dental injuries was 1.6:1. The peak age group of children with dental injuries was the 1-to-2-year-old age group. Laceration of the lip was the most predominant injury to structures of the oral cavity, accounting for 62.8% of the dental injuries. The peak month for dental injuries was June, and 61.2% of the dental injuries occurred in the home.

This is the youngest patient reported in the literature with bilateral mandibular dentigerous cysts. This report confirms the importance of a panoramic radiographic examination in diagnosing bony lesions of the jaws. Early diagnosis and aggressive treatment of these lesions is essential to avoid the undesirable sequelae that could occur without treatment. Dentigerous cysts are bony lesions that have the potential to produce neoplasms.

A patient with Rubinstein-Taybi syndrome is presented with the characteristic clinical features including small and short stature, severe mental retardation, and small maxilla with a dental malocclusion. Treatment for this patient was accomplished utilizing a general anesthetic. These special patients who lack the ability to accept dental treatment in the normal situation require extensive and comprehensive dental treatment compared with nonhandicapped patients.
