effect of benzocaine 20% topical anesthesia on pain levels when placing separators in children receiving hall technique crowns

Conditions: Effect of Benzocaine on Pain

Summary: the goal of this rct is to investigate the immediate effect of benzocaine 20% topical anesthesia on initial pain and discomfort levels associated with the placement of elastomeric orthodontic separators in children who are receiving hall technique crowns on primary molars, among children who have attended the pediatric dentistry department, dubai dental hospital (ddh), mohammed bin rashid university (mbru) in dubai, the united arab emirates (uae).

the primary objective of this rct is to assess the immediate effect of benzocaine 20% topical anesthesia on the initial pain and discomfort experienced during the placement of elastomeric orthodontic separators in pediatric patients undergoing hall technique crowns for their primary molars. this study will be conducted among children aged 4-10 years old, receiving dental care at the pediatric dentistry department of dubai dental hospital (ddh), mohammed bin rashid university (mbru) in dubai, united arab emirates (uae). the research will involve recruiting a sample of 32 pediatric patients aged between 4 and 10 years who require 2 hall technique crowns on their primary molars and are scheduled to undergo the placement of elastomeric orthodontic separators as part of their treatment. the participants will be randomly assigned to receive benzocaine 20% topical anesthesia prior to separator placement on either the right or left side of their mouth, and the other side receiving a placebo (e.g., children's toothpaste) before separator placement. data collection: following the placement of elastomeric orthodontic separators, participants will be asked to rate their pain and discomfort levels immediately after the procedure using the wong-baker faces pain rating scale. in addition to pain and discomfort assessments, demographic data (e.g., age, gender) and clinical information (e.g., specific teeth undergoing treatment) will be collected for each participant. the study will employ rigorous blinding procedures to ensure that the participants are unaware of the assigned treatment (benzocaine or placebo) during the procedure and data collection phases. the principle investigator will only be aware of which side of the mouth will be receiving benzocaine just before the procedure via a sealed envelope randomisation. statistical analyses will be conducted to compare the pain and discomfort levels between the two treatment groups. the findings of this study will contribute valuable insights into the efficacy of benzocaine 20% topical anesthesia in managing pain associated with elastomeric orthodontic separator placement in pediatric dental patients undergoing hall technique crown procedures. ultimately, the results will inform clinical practice and improve the quality of care provided to pediatric patients undergoing dental procedures.
