Abstract
Introduction
Personal protective equipment is mandatory to protect patients and professionals from diseases, especially in the dental environment. The risk of gloves micro-perforations is imminent when using sharp instruments or cleaning them up during lengthy clinical procedures.
Objective
This study evaluated the integrity of sterile and non-sterile gloves before clinical use and clarified whether friction with disinfectant solution modifies surface morphology and integrity.
Material and method
Samples of gloves from four different brands were divided into two groups: (1) Sterile surgical gloves (n=260) and (2) Non-sterile gloves (n=260). They were scissored and placed in Ostby’s arch so that three solutions - distilled water, ethanol 70°, ethanol 96° - were rubbed with a cotton swab. After 30s, 5, 10, and 15 minutes of solution rubbing, samples were verified by a Scanning Electron Microscope. The pore sizes were measured by Image J software.
Result
Regardless of the brands, all gloves have been significantly affected by solutions and assessment periods. In general, remarkable changes were evident with ethanol 70° and 96°, and higher pore diameters were observed compared to distilled water.
Conclusion
Rubbing disinfectant solutions increases gloves’ pores sizes, and time negatively influenced its quality.
