Evaluating Anxiety Levels and Pain Perception while Administering Local Anesthesia Using Conventional Insulin Syringes and Novel Star Pen Device

Key Points

The aim is to evaluate anxiety levels and pain perception while administering local anesthesia in children using different syringe methods.
Randomized trial comparing conventional insulin syringes and a novel Star Pen device for local anesthesia administration in children.
Assessment of anxiety levels and pain perception during the procedure.
Focus on minimizing discomfort associated with local anesthetic injections.
Children experienced lower reported anxiety levels with the Star Pen device compared to traditional insulin syringes.
Pain perception was reduced with the use of the Star Pen device, enhancing overall patient experience.
Significant differences in anxiety and pain scores between the two methods were noted, with p-values indicating statistical significance.

Abstract

employed methods used to decrease patient discomfort while administering LA. 4 One of the most efficient methods is the use of an insulin syringe, a hypodermic syringe with a small pump, barrel, plunger, and needle.It is affordable and accessible.The insulin syringe has a small needle with a design that resembles a toy.With calibrations at 0.025 mL intervals, the insulin syringe provides regulated release IntroductIonAccording to Celsus, pain is a stressful condition and is one of the primary indicators of inflammation.Pain is usually described as a symptom rather than a sign, as it is subjectively experienced only by the patient.According to the International Association of Pain (2011), "Pain is defined as an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage." 1 Managing pain is the most difficult task and provides the basis of good behavior management, particularly in children.In most cases, a local anesthetic injection is used to achieve this.Although this approach is quite successful, it is also among the most important reasons for children's fear and anxiety, because just the thought of the conventional needle makes them more anxious than the actual treatment. 2 The delivery of local anesthesia (LA) has become a nightmare for the majority of children, mainly due to the penetration of the sharp needle into the oral mucosa.Painless injections are commonly used in pediatric dentistry and are essential for effective treatment outcomes. 3 They assist in reducing the child's apprehension, which eventually results in positive patient behavior in the future.Topical gels, precooling of the administration site, employment of short needles, buffering of the LA, use of vibrating devices, and computer-assisted administration are some of the commonly 1-
