The provision of dental care for patients with natural rubber latex allergy: are patients able to obtain safe care?

Comparative Assessment of Hypersensitivity Reactions on Use of Latex and Nitrile Gloves Among General Dental Practitioners: A Cross-Sectional Study

Background  Latex gloves are used more frequently by dental, medical, and other health workers and their allergy has also increased as a result, dentists are frequently exposed to latex or nitrile gloves for extended periods. This prolonged exposure often leads to local symptoms such as itching and erythema rashes. However, some dentists experience more severe systemic reactions, including swelling, wheezing, breathlessness, and even an increase in blood pressure. Latex gloves have recently been replaced with nitrile gloves, powder-free latex gloves, and other preventive measures to avoid allergies. Latex allergies are more common than nitrile allergies, as they are hypoallergic with properties such as tear-resistant and provide an equivalent level of defense against various dental materials and procedures. Women experience more allergic reactions than men. Not only are dentists exposed to this allergy but the patient can also be exposed during the procedure. This study aimed to assess hypersensitive reactions to the use of latex and nitrile gloves among general dentist practitioners and dental students. Methods A cross-sectional study was conducted in Wardha, Maharashtra, India, to evaluate allergic reactions to latex and nitrile gloves among general dental practitioners and dental students at college. A questionnaire-based study was conducted with a sample size of 356. The self-administered survey inquiries about glove compliance, the time they wear the gloves, regular glove use, and problems related to latex or nitrile contact. In addition, dentists and dental students' personal histories of allergies to medications, dental materials, disinfectants, or other chemicals were noted, as well as signs and symptoms they experienced from prolonged contact with gloves. Result The total number of responses collected was 356. The investigated dentists were 274 and 82 were students, out of which 122 (34.3%) were male and 234 (65.7%) were female. Responses showed that 224 (62.92%) used latex gloves, and 132 (37.08%) used nitrile gloves. Among 356 participants 175 showed symptoms by the use of both latex and nitrile gloves, out of which 85.14% showed allergy to latex and 14.85% to nitrile gloves. All 175 individuals showed type IV hypersensitivity, and none of them showed type I. Conclusion Latex gloves are not the only option for dentists who experience itching when wearing gloves; they can also use powered-free latex gloves and nitrile gloves or take precautions such as not using oil-based cream, washing their hands, or taking pharmaceuticals such as cetirizine, pheniramine maleate, etc. However, when symptoms worsen and include erythema, swelling, wheezing, and in some cases, anaphylactic shock may occur they tend to use alternative gloves.

The use of latex and non-latex gloves and dental equipment in UK and Irish dental hospitals

Aim To identify glove usage within UK and Ireland dental hospitals as well as the use of latex- and non-latex-containing dental equipment.Method A self-completed questionnaire was disseminated to 16 dental hospitals in the summer of 2017. The survey concerned their current use of latex and non-latex gloves and dental equipment. In addition, information was sought regarding any problems associated with non-latex and latex gloves.Results The questionnaire response rate was 13/16 (81%), of which 100% reported the use of non-latex examination gloves. The majority were using nitrile gloves. Twelve of the 13 dental hospitals would use examination gloves for simple extractions and 11 would use sterile gloves for minor oral surgery. In ten hospitals (77%), the sterile gloves were always non-latex, and again, the majority were nitrile. Latex-containing dental equipment including orthodontic bands, prophylactic polishing cups and dental dam was still being used within some dental hospitals, but to a much lesser extent than non-latex.Conclusion All dental hospitals were using latex-free examination gloves and were showing a move towards latex-free dental equipment. This usage is comparable to what has been seen in general dental practice and follows the trend towards latex-free dentistry.

Latex and synthetic rubber glove usage in UK general dental practice: changing trends

Objectives

To evaluate the current routine use of latex gloves and latex containing dental dam in UK general dental practice.

Methods

A questionnaire was disseminated to 89 general dental practitioners (GDPs) in June 2017. The survey concerned their current, routine use of latex gloves and latex-containing dental dam in general dental practice. In addition, monthly sales figures of gloves classified by material, were obtained from a UK dental supply company, for 2015–2017.

Results

The questionnaire response rate was 84 (94%), of whom 90% reported using non-latex (non-sterile examination) gloves for their routine dentistry. The majority were using nitrile gloves. All GDPs surveyed would use examination gloves for routine extractions, and 76% would use examination gloves for surgical extractions. The majority (75%) reported using non-latex dental dam. Sales of nitrile gloves were significantly higher than for latex gloves, with a continuing trend in the reduction in volume of sales of latex gloves.

Conclusion

The majority of GDP's now routinely use non-latex containing gloves and dental dam in their clinical dentistry. Nitrile gloves are predominantly used. Examination gloves are used for straightforward extractions, with many practitioners also using them for minor oral surgery. Sales of latex containing gloves are continuing to decrease.

Clinical significance

The routine use of latex-containing products in UK dental practice is low and likely to reduce further, with on-going benefit for the dental practitioner, latex allergic patients and prevalence of latex allergy in the general population.
