The purpose of this study is to clinically evaluate the effects of a school-based behavioral intervention, CATCH Healthy Smiles, to reduce the risk of dental caries in a cohort of kindergarten through 2nd grade (K-2) children serving low-income, ethnically-diverse children,to determine the impact of CATCH Healthy Smiles on child behavioral, psychosocial, and environmental outcomes beginning in K through 2nd grade, compared to children in the control schools and to examine the extent to which the child behavioral, psychosocial, and environmental factors mediate the improvements in child caries risk.

All control schools will receive training and materials for the CATCH sun safety curriculum. Ray and the Sunbeatables®: A Sun Safety Curriculum is an evidence-based curriculum educates children, parents and teachers about sun protection and promotes sun safety behaviors in an effort to reduce children's lifetime risk of developing skin cancer. Training will be conducted with booster trainings yearly.
This intervention includes toothbrushing which will be implemented as a daily activity to develop skills and technique,classroom curriculum, which includes theory-based interactive lessons on oral health care,the physical education component consisting of an activity box containing different structured physical activities that will integrate the nutrition and oral health education messages, all cafeteria-based intervention materials including the "tooth friendly" Eat Smart guide, signage, nutrition labeling, menu planning and labeling using the tooth-friendly Go-Slow-Whoa CATCH terminology will be provided to the food service staff that is displayed across the cafeteria and sent home to parents and parents will be provided with tools and tips for maintaining oral health with website resources,parent-child homework activities, send-home infographics on dental care, parent-monitored tracking of child oral health,family fun nights in schools, and social media.

Number of children with good oral hygiene as measured by the child plaque index
The plaque score will be measured using the plaque index of Silness and Loe. Six teeth will be examined for presence of plaque/ materia alba and food remnants and calculus. The index will be a numerical score (0-3) as follows: 0 = No Debris or stain; 1 = Soft debris or stain covering no more than 1/3 of tooth surface; 2 = Soft debris or stain covering more than 1/3 of tooth surface and less than 2/3 of tooth surface; 3 = Soft debris or stain covering more than 2/3 of tooth surface.
