An apparatus, a method, and a computer program product for effective communication routing of unicast and broadcast data traffic in wireless ad-hoc networks are presented. The floss picks fit into a retainer component and are positioned to insert the floss strands into the interproximal spaces between the user’s teeth. A combustion head is coupled with the housing and configured to direct air and fuel to a combustion chamber in fluid communication with the exhaust flow path. The controls are surrounded by a cosmetic bezel that hides the actual mounting mechanism and circuitry. Furthermore, a stack structure in which a silicon oxide or low interface state oxide film is formed is included between the diffusion layer and the junction leak control film.
