Green Lens Glasses: A Simple Solution to Dental Anxiety and Pain

Dental anxiety is a widespread issue that can make oral surgeries particularly daunting for many patients. In a recent study, researchers investigated the effectiveness of wearing glasses with green lenses in reducing dental anxiety, blood pressure, heart rate, and intraoperative pain in patients undergoing first-time third-molar surgery.

Methods

This study was designed as a randomized and parallel-group clinical trial to ensure robust and reliable results. The participants’ dental anxiety levels were initially measured using a visual analog scale (VAS) and the State-Trait Anxiety Inventory (STAI). These tools provided baseline measurements of anxiety levels. Concurrently, blood pressure, oxygen saturation, and heart rate values were recorded to establish a comprehensive physiological profile of each patient. Participants were then randomly assigned to one of two groups: one group received glasses with clear lenses while the other group received glasses with green lenses. After wearing their respective glasses for 10 minutes, all parameters were measured again to obtain preoperative data. Patients continued to wear their assigned glasses throughout the operation. Post-operation, they were asked to estimate their intraoperative pain using the VAS.

Results

The study included 128 patients who underwent first-time third-molar surgery. The findings revealed significant differences between the groups in terms of changes from baseline to preoperative measurements:

• Anxiety Reduction: There was a statistically significant reduction in dental anxiety among patients who wore green-lens glasses compared to those who wore clear-lens glasses.
• Heart Rate: A noticeable decrease in heart rate was observed in the green-lens group.
• Intraoperative Pain: Patients who wore green-lens glasses reported significantly lower intraoperative pain levels.

The results suggest that wearing low-cost, easy-to-use green-lens glasses for just 10 minutes before an operation can effectively reduce dental anxiety and heart rate. Moreover, continuing to wear these glasses during the surgical procedure can help mitigate intraoperative pain.
