Evaluation of Cellular Phones for Potential Risk of Nosocomial Infection amongst Dental Operators and Auxiliary Staff

BACKGROUND This study evaluates cellular phones for potential risk of nosocomial infection amongst dental operators and auxiliary staff in a dental school. MATERIALS AND METHODS Each participant's mobile phone was first cleaned with 70% isopropyl alcohol swab. Following the cleansing protocol, the partakers were asked to make a short phone call. The mobile phones were then washed aseptically by rotating damp cotton swabs with sterile normal saline. Bacterial growth was identified on sheep blood agar and McConkey's agar plates. Sabouraud dextrose agar media was used for fungi species. Descriptive statistics was established with the data statistically explored with SPSS version 17.0. RESULTS About 50% of dental professionals had shown active bacterial and fungal growth in which 35% (n=35) were dental operators and 15% (n=15) were dental nurses. 53% Gram-positive organisms, 2% Gram-negative organisms, and 3% fungi were identified growths on cellular phones. CONCLUSION Thus, it can be concluded that the cellular phones of dental operators as compared to auxiliaries can act as a potential source of nosocomial infection.
