<p>Dental hand tools (140) including disposable water and air treatment cartridges (50). In various construction, cartridges (50) containing selected arrangements of disinfectant media mount to a detachable, hand tool adaptor manifold (2) or to an integral hand tool manifold (142). The cartridges (50) purify water and air discharged from the hand tool (140) and direct liquid and airflow over external surfaces of the cartridge (50) to an interior cavity (156) containing a halogen disinfectant media (e.g. a multivalent iodine resin) and/or halogen scavenger media and porous spacers. A retainer may interlock the cartridge to the manifold (142) and means may be included to prevent leaching of the disinfectant by the scavenger media. Various constructions of handpieces, syringes and scalers compatible with alternative detachable, adaptor manifold or having integral cartridge manifolds are disclosed. Spray tips with integral manifolds and detachable cartridge manifolds which align to water and air discharge ports are also disclosed.</p> |
