However, currently there are no programs in the urban school districts of Oklahoma to test the effect of xylitol based snacks on children. Hence, the intent of this research is to implement and measure the changes in rate of dental caries among children in the urban school districts of Oklahoma City, Oklahoma. Methodology This study is intended to implement and measure the difference (if any) in the occurrence of dental caries among children in seven urban school districts of Oklahoma City, Oklahoma. The study is developed based on the educational recommendations and research literature that indicate that substituting sugar with xylitol in snacks eaten by children is a very promising option. This is so because xylitol has powerful anti-cariogenic and tooth protecting properties (Lam, Riedy, Coldwell, Milgrom, & Craig, 2000). Xylitol is also known to significantly reduce the levels of Streptococcus mutans in saliva and plaque, which are the main causes for tooth decay (Lynch & Milgrom, 2003). Sample About 2000 children from the 1st to 6th grade from six urban schools of Oklahoma City, Oklahoma will be randomly selected for this study. These children will be randomly assigned to either the treatment group or the control group. Children in the treatment group will be given xylitol based gummy worms and cookies while those in the control group will continue to eat the regular snacks available in the school cafeteria. Children from all racial and ethnic backgrounds will be equally distributed

between the treatment and control groups. Children will also be classified based on their gender and will be equally represented in the treatment and control groups. Instrumentation The dmft (decayed, missing and filled teeth) score for the primary teeth and DMFT (decayed, missing and filled teeth) score for the permanent teeth will be used to assess the dental health of children. Both these scores are assigned after a systematic examination of the crown and exposed root of every primary and permanent tooth using a mirror and explorer. Following the examination, each crown and root will be assigned a number which is recorded in boxes corresponding to each tooth in the dmft/DMFT score chart. Care will be taken to record all ‘tooth colored’ fillings which are usually difficult to detect. Data Collection Each participating child, enrolled in the study, will be examined by a dentist and given a dmft/DMFT score. This dmft/DMFT score will establish the baseline for each child. Under the supervision of their teacher, each child in the treatment group will be provided xylitol based snacks during the two snack breaks in school, while those in the control group will be provided the regular sucrose or sorbitol based food items that are currently available in the school cafeteria. The study will be implemented in the month of August 2012 and the dental health of the treatment group and control group will be monitored for a period of eight years. Informed consent will be collected from the parents of each child participating in the study. Principals of schools will be contacted to gain approval for this study and to ensure their commitment and participation in this study. The research proposal for this study will also be sent to the institutional review board at the University of Oklahoma for approval. The data collected for each participating child will be used only for the purposes of this research
