“…The move away from natural rubber latex (NRL) towards synthetic latex in dentistry was led by the introduction of polyvinyl chloride (PVC) and, more recently, nitrile gloves. Unfortunately, PVC gloves are prone to pre-existing pinhole defects, 21 exhibit a low puncture resistance 22 and are reported to significantly decrease in integrity under the stresses of clinical use, compared with latex gloves. 23 As a result, attention has recently been focused on nitrile gloves as a possible alternative to dental gloves manufactured from natural latex.…”

Introduction Examination gloves manufactured from natural latex have been the predominant glove choice to date in dental practice. However, concerns over hypersensitivity have resulted in the use of alternatives such as nitrile gloves. The aim of the current study was to assess the incidence of pre-existing pinhole defects in nitrile examination gloves. Methods Air inflation, followed by water submersion, was used to assess the incidence of pre-existing pinhole defects in five nitrile and two latex glove types. The gloves were filled with a constant volume of air and submerged in 3 litres of water for 10 seconds while being observed for air bubbles which would indicate pinhole defects. The position and number of pinholes were noted for 100 gloves of each type investigated. Results The incidence of pre-existing pinholes for latex gloves was 0% for the non-sterile surgical latex glove type and 3% for the powdered latex examination glove type, with pinholes located on the thumb, middle finger and ring finger. Of the nitrile gloves evaluated, three types were assessed to have no pre-existing pinhole defects. One type had a 2% incidence of pre-existing pinhole defects -one pinhole located on the thumb region of the glove and one on the ring finger portion of the glove. The fifth nitrile glove type had one pre-existing pinhole defect located on the middle finger. Significance All glove types examined met the European Standard (EN 455-1) and there was no statistically significant difference between glove types. However, the nitrile gloves generally exhibited less pre-existing pinhole defects than the latex examination gloves.

“…The nitrile glove types assessed had higher stiffness values, which explained the greater resistance to puncture reported in the current study. The nitrile gloves exhibited superior puncture resistance properties, as stated in studies previously [25][26][27][28] as compared with latex gloves. However, as highlighted by Hasma and Othman 30 and Checchi et al 31 the gloves' elastic properties influence the passage of liquid through punctures.…”

“…PVC gloves are prone to pre-existing pinhole defects, 18 exhibit a low puncture resistance 19 and are reported to significantly decrease in integrity under the stresses of clinical use compared with latex gloves. 20 Therefore nitrile gloves have been considered a possible alternative to dental gloves manufactured from natural latex, especially for use by those individuals allergic to latex protein.…”

“…[25][26][27][28] Fisher et al 28 reported that the thickness of the glove type was not an accurate predictor of puncture resistance as the thinnest glove assessed, the nitrile glove type, exhibited the highest puncture resistance and recommended the use of nitrile gloves for latexsensitised surgeons. In the current study, the Microtouch latex glove type assessed was the thickest (0.1778 mm), however, the three nitrile glove types Nitratouch (0.1143 mm), Safeskin (0.12446 mm) and Microtouch nitrile (0.1778 mm) exhibited a significantly higher puncture resistance.…”

“…In the current study, Microtouch latex gloves exhibited an overall mean puncture resistance of 3.39 ± 0.76 N and for specimens from the index finger alone, a mean puncture resistance of 3.51 ± 0.43 N. This is a higher value than that evaluated for latex examination glove types from previous studies. [25][26][27][28] Dental injection Needle Manson et al 29 devised a novel method to quantify the force necessary for a representative 0.45 mm diameter needle to penetrate a glove specimen. The initial and maximal penetration forces were recorded for Biogel latex gloves to be 0.04 ± 0.01 N and 0.05 ± 0.01 N respectively, similar to values recorded in the current study.…”

ObjectiveThe aim of the current study was to assess the puncture resistance and stiffness of nitrile and latex dental examination gloves. Methods Puncture resistance was measured by employing an adapted version of ASTM F1342-91 using both a 316 stainless steel puncture probe (0.8 mm diameter) and a dental injection needle (0.45 mm diameter) interfaced to a tensile testing apparatus. Glove specimens (12 cm length, 1.5 cm breadth) were removed for modulus (M100) evaluation by assessing the force required to elongate the specimen to 100% of the original length. Glove samples were also aged to investigate whether puncture resistance and M100 values varied with aging at 70°C for 7 days in an air-circulating oven. Results The nitrile glove types were assessed to have significantly higher puncture resistance compared with the latex glove type when the steel puncture probe was the pentrometer when using the one way analysis of variance (ANOVA) at the 95% significance level. Interestingly the puncture resistance for the latex glove type was significantly higher (P < 0.001) when a dental injection needle was used as the pentrometer compared with the nitrile glove types. The M100 values were significantly higher for the nitrile glove types for which the stiffness increased when the gloves were aged (P < 0.001). Conclusions The higher stiffness values resulted in increased puncture resistance when the nitrile glove specimens were aged irrespective of the pentrometer type. However, the ability of latex to re-seal itself on puncture may be beneficial when considering the protection potential of each glove type against breaches in cross infection. For clinicians that have experienced an adverse reaction to natural latex gloves, the results of the current study indicate that nitrile gloves are available at reasonable cost and offer the clinician comparable resistance to puncture with latex gloves.
