Efficacy of various surface disinfectants on an irregular surface.

Representative samples of hard surface disinfectants were tested against Pseudomonas aeruginosa (ATCC 27853) on frosted glass rods. The same protocol was followed by two investigators on 100 rods for each product tested. Results showed Sporicidin surface disinfectant (Ash Dentsply, York, Pa.) and household bleach 1:10 to be most effective against P. aeruginosa. Lysol disinfectant spray (Lehn & Fink Products, Montvale, N.J.), performed similarly whereas Biocide (Biotrol International, Woods Cross, Utah) failed to inhibit growth on more than half of the rods treated. Failure of the iodophor may be attributed to the use of cotton-filled gauze, because cellulose is believed to react with nascent iodine.

Identification of pathogens in the condensates from air pressure systems in dental offices.

We examined the air pressure systems in 23 dental offices and found growth of Group A Streptococci and/or Staphylococcus Aureus in 91 percent of them. We also examined nine handpiece lines from these 23 offices and found growth of pathogens in 78 percent of them. Correlation of the growth found in the handpiece lines and the growth found in the air pressure tanks needs further study to determine if an interrelationship exists between these two areas of contamination. However, contamination does exist in both areas and these areas deliver contaminated air under pressure to the oral environment. We need to consider mechanisms for filter entrapment or sterilization of these pathogens.
