Abstract : Water quality in the dental unit water lines (DUWLs) is important to the patients and dental healthcare personnel as they are at risk of being infected with Pseudomonas aeruginosa. The aim of the present study was to determine the occurrence of P. aeruginosa contamination in DUWLs and to study the antibiotic resistant profile. A total of 101 dental water samples including air/water spray (26), Ultrasonic scalar (24), Air rotor compressor (26) and Distilled water (25) were screened for P. aeruginosa and 67 samples were found to be contaminated by P. aeruginosa. All these isolates were further subjected to antibiotic susceptibility testing. Among these, 63 (94.02%) showed resistance to ampicillin followed by 39 (58.20%) to amoxicillin, 11 (16.41%) to cefepime, 5 (7.46%) to aztreonam and 1 (1.49%) to gentamicin.
