Permeability of protective gloves used in dental practice
Quintessence international (Berlin, Germany : 1985), 1994
Two brands of latex rubber gloves and one brand of polyvinyl chloride glove were examined for their permeability. New and used gloves were included. All of the gloves were examined visually and then subjected to an air leakage test, an electrical test, and a microbiologic test. Permeability was evaluated independently by two researchers in a blind manner. Statistical analysis showed that there were no significant differences among the three brands of gloves or with respect to the usage periods, according to visual inspection and the air leakage test. Conversely, there were significant differences among each of the three brands of gloves and with respect to usage periods, according to the electrical and microbiologic tests.
The Incidence & Pattern of Micro Perforation of Surgical Gloves After Single Use
2020
Aim & Objectives: Concern about the transmission of infection from patients to healthcare workers & vice versa is increasing. According to occupational safety & health administration, USA guidelines, gloves must be worn whenever there is a reasonable likelihood of contact of body fluids of patients to health personnel's in order to prevent contamination. The aim of this study is to report the pattern & incidence perforation of surgical gloves after single-use during different dental &maxillofacial surgical procedures & also to compare the perforation rate in single & double gloving methods during different elective& emergency oral & surgical procedures.Material & Methods: This prospective study was done for six months in the department of oral &maxillofacialsurgery. All the gloves used during elective & emergency, minor & major surgical procedures were collected. Both visual & hydro insufflations techniques were used to check the gloves for perforation & parameters were recorded...
Permeability of medical gloves to mono- and dimethacrylate monomers in dental restorative materials
International journal of occupational safety and ergonomics : JOSE, 2002
Dental personnel manually handle methacrylate-based restorative materials, which can cause skin irritation and allergies. The protection given by different types of medical gloves is not well known. Breakthrough time (BTT, min) was used as a measure of protection according to a European standard, using 2 test mixtures consisting of respectively 3 and 5 monomers. Fourteen gloves representing natural rubber latex, synthetic rubber, and synthetic polymeric material were tested. The BTT ranged from some minutes to more than 2 hrs for the 4 monomers with a molecular mass less than 300. The longest protection was recorded for Nitra Touch (nitrile rubber), Tactylon (synthetic rubber), and Metin (PVC).
BackgroundThe COVID-19 pandemic has created global shortages of personal protective equipment (PPE) such as medical exam gloves, forcing healthcare workers to either forgo or reuse PPE to keep themselves and patients safe from infection. In severely resource-constrained situations, limited cycles of disinfection and extended use of gloves is recommended by the U.S. Centers for Disease Control and Prevention (CDC) to conserve supplies. However, these guidelines are based on limited evidence.MethodsSerial cycles of hand hygiene were performed on gloved hands using alcohol-based hand rub (ABHR) (six and ten cycles), 0.1% sodium hypochlorite (bleach) solution (ten cycles), or soap and water (ten cycles) on three types of latex and three types of nitrile medical exam gloves, purchased in the United States and India. A modified FDA-approved water-leak test was performed to evaluate glove integrity after repeated applications of these disinfecting agents. 80 gloves per disinfectant-glove t...

The human cost of the COVID-19 pandemic has taken a great toll, and led, around the globe, to a shortage in personal protective equipment (PPE) such as medical exam gloves. To face this shortage and keep themselves and patients safe, many front-line healthcare providers have been overextending the life of PPE. Though not ideal, one pragmatic solution often used is the practice of sanitization and extended use of existing PPE. The data produced by these experiments should help determine an acceptable reusability window of PPE in a working environment, by which the effective use time may be extended and justified. The effect of repeated sanitization, using soap and water, on the mechanical performance was investigated for latex and nitrile elastomeric medical exam gloves. Tensile tests were performed for various manufacturer brands commonly used in the United States (Glovepak Europa, Polymed and Sempersure) and India (Surgiglove). Tensile test samples were prepared for each studied gl...
Permeability of latex gloves after exposure to 6 chemical agents
Quintessence international (Berlin, Germany : 1985), 2007
To assess the effects of exposure to 6 chemical agents on the permeability of latex gloves by dye permeability test and to qualitatively evaluate the microscopic changes in the ultrastructure of the gloves. The middle fingers of 35 medium-sized, nonsterile latex gloves were used. The chemical agents tested were eugenol, 5% NaOCl, 17% EDTA, 0.2% chlorhexidine gluconate, Cresophene (Septodent), and Chlorispray (Anios). Following treatment for 15 minutes with each chemical agent, glove fingers were filled with 10 mL of 0.02% erythrosine dye solution. Then the outer glove surface was washed with 10 mL of distilled water at intervals of 15, 30, 45, and 60 minutes. A spectrophotometer was used at 530-nm wavelength to determine the percentage of absorption from each collected washing solution. The results were compared with the values obtained from untreated gloves. Additionally, small pieces of the glove samples were examined by SEM to determine whether any ultrastructural changes occurre...

In dentistry, allergic contact dermatitis to acrylates and allergic contact urticaria to latex are important occupational hazards. There is a need to identify non-latex gloves which are suitable for dental work but at the same time provide adequate protection against acrylate monomers. In a previous study, a new open-chambe r system was used for testing the in vivo protection of 6 different gloves against an acrylate-containing ethanol-based dental adhesive. A nitrile glove gave the best protection among the gloves suitable for dental work. In the present study, the test model was used to investigate the in vivo protection of 7 non-latex gloves against a dental bonding product containing 2-hydroxyethyl methacrylate (2-HEMA) in an acetone/water vehicle. Eight 2-HEMA-allergic patients participated. Two neoprene gloves gave the best protection. The protection of the poorest glove was comparable to that of the positive control (no glove). The study produced in vivo data useful in the implementation of individual preventative measures against contact allergy to acrylates.

The objective of this study was to quantify the colony forming units (cfu) on latex procedure gloves in the beginning, middle, and end of the containers in real (professional) and controlled (researcher) gloving situations; evaluate the microbial load of the gloves, considering the time of exposure in the environment. This comparative prospective study was conducted at an intensive care unit of a teaching hospital. The microbiological data was collected from the gloves using digital-pressure. Microbiological evaluations were performed on 186 pairs of gloves: 93 in the control group and 93 in real gloving situations. In the control group, the average cfu was 4.7 against 6.2 in the real gloving situation. Hence, no statistically significant difference was found (p=.601). In addition, the cfu values of gloves in the beginning, middle and end of the containers also did not show any significant differences (p>.05). The most common strain was Staphylococcus spp. The time of exposure in...
