Abstract Background Children with hearing impairment (HI) face communication challenges during dental procedures due to hearing loss. Studies suggest that distraction techniques, like virtual reality (VR), can effectively divert their focus from stressful stimuli, resulting in a more comfortable dental experience. The present study aims to assess the effectiveness of distracting children with moderate to severe (HI) with virtual reality glasses that show cartoons in sign language during pulpotomy treatment compared to conventional management techniques. Methods Forty children aged five to seven participated in a randomized controlled parallel two-arm clinical trial-the type of behavioral management employed determined which two groups children were randomly placed into. Group I (Study group) used virtual reality glasses as a diversion, while Group II (Control group) used the conventional behavior management approach. Local anesthesia was administrated, and a pulpotomy procedure was performed on the selected tooth, followed by stainless steel crown restoration (SSC). There were three methods used to assess dental anxiety before and after the procedure: the physiological method, which used heart rate (HR); the objective measure, which used the Venham Clinical Anxiety Scale (VCAS); and the subjective measure, which used the modified Facial Affective Scale (FAS). An independent t-test was employed for HR analysis of the difference between the groups as a continuous variable. The Pearson Chi-square test assessed differences between groups for categorical variables, such as (VCAS) (FAS). Results No significant differences were found in mean (HR) or (VCAS) between the two groups throughout the procedures: during local anesthesia (p = 0.659, 0.282), pulpotomy (p = 0.482, 0.451), and stainless steel crown preparation (p = 0.090, 0.284). Anxiety levels by (FAS) remained statistically comparable between the two groups before and after the procedures (p = 0.507, 0.749), respectively. Conclusions The use of VR glasses revealed no significant advantages in managing children with HI during the dental visit compared to the conventional method of child behavior management. Trial registration The trial was prospectively enrolled on 11/11/2023 under the identification number NCT06153823 on ClinicalTrials.gov.
