Behavior of Children During Dental Care With Rubber Dam or Cotton Roll Isolation, A Randomized Study

Abstract

Background: The establishment of the dental dam improves dentist working conditions and patient protection. The purpose of this study was to analyze the behavior of the child during dental care with or without a dam.Methods: In this interventional randomized study, 51 patients are divided into two groups, one with a rubber dam and the other cotton roll isolation. Their behavior was observed during the treatment of temporary molars. The duration of the treatment, the patient's feeling with a visual analogue scale (VAS), the behavior (B) of the child measured with a hetero-evaluation scale (modified Venham scale) and the cardiac frequency (CF) were measured.Results: The group treated with a rubber dam has a significant decrease in the various stress parameters that have been identified (B, p value = 0,034; CF, p value = 0,015).Subgroups of patients with and without nitrous oxide sedation were compared and similar results were obtained. Data were compared within groups using paired tests and between groups using unpaired tests. Differences between time points were compared to 0 by a one-sample test. Categorical data (Venham scale, VAS) were analyzed using non-parametric tests.Conclusions: Isolation with a rubber dam reduces child’s stress during dental care. Although it is slightly more time-consuming and training is necessary for a quick and effective placement, it allows to perform dental care in the best possible conditions, while reducing dental anxiety in young patients.Trial registration: Retrospectively registered 39217 in ISRCTN Register (London, UK) with ISRCTN15046229.
