註釋Abstract: The objective of this study was to conduct an open-ended interview with parents of caries-free children and children with early childhood caries (ECC) to determine if differences exist on a number of factors contributing to dental caries. Plaque samples were also obtained from all subjects in order to provide a microbiologic sample of the bacterial species present in health and at various stages of the caries process. 50 Healthy Control subjects were included in this study as well as 48 ECC subjects. Demographic information and responses to a 15 question survey were obtained from the parents prior to plaque sampling. Plaque samples were obtained from patients who met the proper inclusion criteria and were frozen in the laboratory until cloning and sequencing of the bacterial DNA was conducted. A number of significant results were determined between the healthy control and ECC groups. Demographic information revealed that racial differences existed between the two groups with a predominance of White subjects sampled in the ECC group. The highest grade completed by either parent was also higher in the healthy control group. The ECC group reported a much higher history of antibiotic use than the healthy control group. The drink survey revealed that the ECC subjects consumed more juice and soda than the healthy subjects and had a higher frequency of intake of any kind of drink per day than did the healthy group with an average of 7.54 glasses versus 4.78 glasses. The ECC group also demonstrated much higher amounts of plaque present as well as poorer gingival health than the healthy control group. The ECC group reported higher usage of a bottle or sippy cup as well as use between meals and at bedtime than the healthy controls. Finally, the ECC subjects were exposed to cigarette smoke more often in the home as well as in other locations on a regular basis than the healthy controls. The diet questionnaire however, showed no differences between the two groups based on intake of refined starches, refined sugars, unprocessed foods, or meat/eggs. There were also no differences on ingestion of milk, sweetened milk, or added sugar non-carbonated beverages. Our results indicate that perhaps frequency of liquid ingestion is one of the most important contributors to the caries process and that juice and soda intake, in particular should by minimized in order to prevent decay. Further research is needed in order to provide insight as to why some children suffer from such devastating dental disease while others do not. Perhaps this investigation will allow us to refine our questionnaire in order to tease out the most important links to the caries process in the future. We also eagerly anticipate the results from the Molecular Analysis of our subjects in order to study the differences in microbiology at every level of the caries process. All of this information will hopefully advance caries research and eventually provide some clues as to how to prevent caries and eradicate this dental suffering for our patients.
