Background : Dental dam is essential in dentistry; however, the usage is limited due to its high price and the need to import the product from foreign countries.

Objectives : This research studied the feasibility of using the rubber examination gloves instead of normal dental dams. The rubber examination gloves were made from natural rubber latex (natural rubber glove) and nitrile rubber latex (nitrile rubber glove) which routinely used in dental department. Physical properties i.e. thickness, tensile strength, elongation at break and tear strength of dental dam are compared to those of rubber examination gloves.

Methods : With using the one way ANOVA at p-value < 0.05 for statistical analysis.

Results : It was found that the thickness of dental dam, natural rubber glove and nitrile rubber glove were (0.190 ± 0.005) mm, (0.109 ± 0.003) mm and (0.083 ± 0.004) mm, respectively. Tensile strength values were found to be (41.0 ± 1.9) MPa for dental dam, (28.2 ± 1.6) MPa for nitrile rubber glove and (33.6 ± 7.0) MPa for nitrile glove. Elongation at break values were found to be (858 ± 18) % for dental dam, (748 ± 19) % for natural rubber glove and (516 ± 25) % for nitrile rubber glove. Tear strength values were found to be (31.0 ± 4.6) N/mm for dental dam, (45.1 ± 5.8) N/mm for natural rubber glove and (7.7 ± 1.4) N/mm for nitrile rubber glove. It was found that the three sets of each physical property were significantly differences. Considering the properties needed for dental dam application, although the dental dam possessed the highest tensile properties, these properties of natural rubber glove and nitrile rubber glove were considered high enough for use as the dental dam. In addition, the tear strength property of the natural rubber glove was found to be higher than that of dental dam.

Conclusions : It can therefore be concluded that the rubber examination gloves, natural rubber glove in particular, can be used instead of the dental dams.
