Introduction: With respect to the outbreak probability of dangerous infections among the patients, the water sources of dentistry units were taken into consideration, in view of microbial contamination. The objective of this study was to assess of pathogenic organisms of the water used in the dentistry units at Alborz Dental School. Material and methods: In this study, 120 samples from high spe...
OBJECTIVES This study was designed to determine the role of flushing dental water lines for the removal of heterotrophic plate count bacteria, Legionella spp., and free-living protozoa. METHODS Forty dental offices were surveyed in the study. An initial sample and a sample taken after three minutes of flushing were obtained from the air/water syringe at each location. All samples were quantit...
Bacterial contamination in dental unit waterlines (DUWLs) was evaluated by molecular techniques in addition to the conventional culture method. Water samples (n=8) from DUWLs were investigated for heterotrophic bacteria by culture method using R2A agar. The selected bacterial antibiotic-resistance genes and Legionella species-specific 16SrDNA were identified by PCR. The profiles of bacterial co...
Fungi can cause various diseases, and some pathogenic fungi have been detected in the water of dental equipment. This environment offers suitable conditions for fungal biofilms to emerge, which can facilitate mycological contamination. This study verified whether the water employed in the dental units of two dental clinics at the University of Franca was contaminated with fungi. This study also...
OBJECTIVES The purpose of this study was to determine the prevalence and severity of dental fluorosis among patients attending basic health units in Londrina. METHODS Five basic health units of the urban area were randomly selected and 434 children attending these units, born between 1986 and 1989 (9 to 12 years of age), were examined. Diagnosis of dental fluorosis was performed by means of t...
Microorganisms that have been identified in dental unit waterlines (DUWLs) are of concern because they can cause infections, especially in immunocompromised patients. This study aimed to assess the incidence of microbial contamination in DUWLs before and after intervention to reduce contamination, and to investigate the presence of coliforms, Escherichia coli and Pseudomonas aeruginosa. Water s...
Background and Objectives: According to hazardous infection possibility in patients with a weakened immune system, old adults, and children, microbial contamination in the waterlines of dental units has become a recent concern. The aim of the present study was to evaluate the microbial contamination in dental unit waterlines in the School of Dentistry, Qom University of Medical Sciences, Qom, I...
A significant problem with most field dental units is that their suction is too weak to effectively remove debris from the mouth. The purpose of this study was to determine the minimum clinically acceptable suction level for routine dentistry. A vacuum pump was connected to a high-volume dental evacuation line in a simulated clinical setting and different suction airflow rates were evaluated by...
