Disclosed are safe, simple and effective broad-spectrum treatments for halitosis and other microbial infections of the nondental upper respiratory tract useful to treat bacterial and other microorganism species, including anaerobic bacteria. Electromagnetic radiative energy including visible, and optionally, thermal, RF and/or microwave wavelengths, is topically applied to internal surfaces of the upper respiratory tract to destroy or incapacitate superficial microorganisms without the use of antibiotics. One useful apparatus is a handheld energy applicator having a light output head suitable for treating the back of the tongue and the tonsils and which may be interchangeably provided with extensions to reach the sinuses. The energy applicator can be supported and guided by a mounting device held between the subject's teeth, if desired. Useful embodiments of the invention include preparative treatment of the target surfaces with a photosensitizing agent such as an oxidizing agent or a complementary stain. Optionally a pre-treament procedure may be employed to remove detritus and microfloral overgrowths that may mask more deeply resident target microorganisms. Novel treatments include treatment of halitosis by destruction of bacterial species associated with halitosis, such as Atopobium parvulum, by application of non-ionizing radiative energy to the tonsils and the back of the tongue. Another embodiment comprises a candy bar incorporating a halitosis treatment lamp disposed within the candy.

Carpeted floor covering articles comprising carpet pile fibers to which a topical antimicrobial application of solid particles has been applied either during or after product manufacture (such as part of a cleaning or treatment process) are provided. Such a topical treatment includes specific inorganic antimicrobial metal ion-based solid compounds, such as silver ion-exchange compounds, silver zeolites, and/or silver glasses, which may or may not be dispersed within a liquid medium for ease in handling and application. Such treatments also optionally include compositions of stain resistant agents, anti soil-redeposition compounds and liquids, surfactants, antistatic agents, and the like, to impart other characteristics to the target carpeted products. Such carpeted products thus exhibit excellent antimicrobial characteristics at both the surface of the carpet pile, as well as within the pile itself. Furthermore, it has been found that application of such solid metal-ion based antimicrobials permits the ability to increase antimicrobial activity for the target carpet product after vacuuming.

A single use pen-like marking device is disclosed which is useful for marking skin to form marks which persist for a least a week and which are invisible under ambient light but fluoresce under ultraviolet light and to reveal cracks and caries in teeth which are difficult to see under normal light and for visualizing plaque on teeth without leaving a stain visible under normal light. It has a flexible housing with a dry wick-type marking nib in one end which communicates with the interior of the housing and which is impregnated with a skin fluorescing furanone. Inside the housing is a sealed fragile glass tube therein which contains a solvent for the furanone. The marking device is activated by bending the housing until the glass tube breaks and releases the solvent, which saturates the marking nib and dissolves the furanone therein.
