Creating open communication throughout your project or program will instill trust and program "transparency." People are more apt to support a program if they understand it, believe in it and want to see it succeed. Be proactive and share information rather than waiting for someone to ask for it. Provide contact information so people can talk to someone. Programs that are unwilling to share their successes and lessons learned may be trying to hide serious deficiencies or feel that others will "steal the secrets of their success." Although this attitude may be acceptable in the corporate world, it will not contribute to solving any dental public health problems or increase access to care.
