Effectiveness of OptraDam Versus Conventional Rubber Dam Isolation on Dental Anxiety in Children: A Randomized Clinical Trial
This randomized clinical trial demonstrates that the clamp-free OptraDam isolation system results in significantly lower post-treatment anxiety and physiological stress in children undergoing pulpotomy compared to the conventional rubber dam.

For more than a century, dentists have relied on a simple sheet of rubber to keep the mouth dry and safe during procedures. This barrier, known as a rubber dam, is a standard tool in pediatric dentistry because it stops saliva from interfering with the work and prevents children from accidentally swallowing small instruments. However, placing this sheet often requires a metal clamp to hold it tight against the gums. For many children, the pressure of that clamp and the feeling of being restricted can trigger fear, making a routine visit feel like a threat. To address this, manufacturers recently introduced a newer system that uses flexible plastic rings instead of metal clamps, aiming to keep the mouth isolated without the pinch of the traditional tool. The question facing clinicians is whether this newer, clamp-free approach actually helps children feel calmer, or if the traditional method remains the better choice for managing stress.
Researchers at Isfahan University of Medical Sciences set out to find the answer by observing forty-four children between the ages of eight and twelve who needed a specific type of treatment called a pulpotomy, which involves removing the infected part of a tooth's nerve. The team split the children into two groups. One group received the traditional rubber dam with metal clamps, while the other received the newer clamp-free system. Before the treatment began, the researchers measured how anxious each child felt and recorded their heart rates to establish a baseline. They also watched the children closely during the procedure, noting their facial expressions, eye movements, and body language to gauge their distress. After the treatment was finished, they measured anxiety and heart rates again to see how the experience had changed the children.
The results showed a clear difference in how the two groups reacted. The children who received the traditional rubber dam with clamps became noticeably more anxious as the procedure went on. Their self-reported fear scores rose, and their heart rates jumped significantly, climbing from an average of about ninety-two beats per minute before the treatment to over one hundred and eleven beats per minute afterward. In contrast, the children treated with the clamp-free system did not show a significant increase in anxiety or heart rate. In fact, their stress levels remained relatively stable, and their heart rates stayed much lower than those in the traditional group. When the researchers compared the two groups directly, the children with the clamp-free isolation were significantly calmer and showed fewer signs of physical stress than those with the traditional clamps.
The study also looked at how the children behaved during the procedure. A second researcher, who did not know which treatment each child received, scored their behavior based on sounds they made, where they looked, and how they moved. The children in the clamp-free group displayed much less distress in these observations, scoring lower on the scale of negative behavior than the children with the traditional clamps. While the children with the new system did not show a statistically significant drop in their own reported anxiety from before to after the treatment, the fact that their anxiety did not spike like the other group's did suggests the new method was gentler on their nerves. The researchers noted that the traditional method, while excellent for keeping the area dry, seemed to act as an additional source of stress for these young patients.
This work suggests that the clamp-free isolation system offers a more comfortable experience for children undergoing dental nerve treatments, potentially making the procedure less frightening without sacrificing the safety and cleanliness that rubber dams provide. The authors point out that while their findings are promising, the study involved a relatively small number of children from a single location, so larger studies are needed to confirm these results across different settings. For now, the evidence indicates that removing the metal clamp from the equation may help keep a child's heart rate steady and their fear in check, turning a potentially scary moment into a manageable one.
