Evaluation of Conventional syringe and insulin syringe in pain perception during administration of Greater palatine block in pediatric dentistry
Abstract
Background: Effective pain management in pediatric dentistry is crucial for improving patient experiences and compliance. The Greater Palatine Block (GPB) is a commonly used technique for achieving local anesthesia in the posterior maxilla, yet pain perception during its administration can significantly impact children's anxiety and cooperation. This study aims to evaluate pain perception associated with the use of conventional syringes compared to insulin syringes during GPB administration in pediatric patients.
Methods: A randomized controlled trial was conducted involving children aged 5 to 12 years requiring GPB for dental procedures. Participants were assigned to receive the GPB using either a conventional syringe or an insulin syringe. Pain perception was measured using validated scales, including the Wong-Baker FACES Pain Rating Scale and the Visual Analog Scale (VAS). Anxiety levels were assessed pre-injection using the modified Children's Anxiety Scale. Statistical analyses were performed to compare pain scores between the two groups.
Results: Preliminary findings indicate that patients receiving the GPB with insulin syringes reported significantly lower pain scores compared to those receiving the injection with conventional syringes (p < 0.05). Additionally, children in the insulin syringe group demonstrated lower levels of pre-injection anxiety, suggesting that the smaller, less intimidating design of the insulin syringe may contribute to a more positive overall experience.
Conclusion: The use of insulin syringes for the administration of the Greater Palatine Block in pediatric dentistry appears to reduce pain perception and anxiety compared to conventional syringes. These findings underscore the importance of syringe selection in pediatric dental practice and suggest that adopting insulin syringes could enhance patient comfort and improve treatment outcomes. Further research is warranted to explore the long-term implications of these findings on pediatric dental care and patient satisfaction.
