                Abstract

                Objective:  To evaluate feasibility of hand gloves as a rubber dam isolation alternative, in respect of physical
                properties.    Materials  and  Methods:    A randomized controlled trial study design was used.  Three types of
                gloves were tested with two types of a rubber dam used as the control group.  Cut-out pattern of dumb-bell
                shapes were made from 35 samples for each type of groups and tensile strength were tested using Universal
                Testing Machine and the Trapezium X software.  All tests for physical requirements were performed in accord-
                ance with American Society for Testing and Materials D412, Standard Test Methods for Vulcanized Rubber and
                Thermoplastic Rubbers and Thermoplastic Elastomers-Tension.  Findings were analyzed by analysis of vari-
                ance (ANOVA) and differences were compared using a Tukey-Kramer interval calculated at  the 0.05 signifi-
                cance level.  Results:  Heavy gauge rubber dam has the highest Mean (calculated at the 0.05 significance level)
                except for maximum stress calculated at entire area.  Medium-gauge rubber dam has significantly higher tensile
                                                                                          2

                N/mm  (±3.27366) is more than the minimum requirement specified by American Federal Specification ZZ-R90B
                                                                           2
                Rubber Dam (Dental, 1985) (4000 pounds per square inch or 27.6 N/mm ).   For all variable tested, all groups
                are significantly different from each other.  The mean square between the groups was quite large. Conclusion:
                This study shows that there are significant differences between the physical strength of latex gloves when com-
                pared to rubber dam.  However, the comparison between thickness and tensile strength among various rubber
                dam, did not correspond proportionately.  Only one type of rubber gloves met the minimum requirement but that
                is just one aspect.  In view of these mixed results, more research is needed before we can conclude that it is
                feasable that we use hand gloves to replace rubber dam.

                Key words:  Dental dam, latex examination gloves, physical properties, tensile strength.
