Comparing Controlled Flow Delivery Dentapen® Technique to Traditional Syringes on Pain Perception During the Administration of Anesthesia Among A Group of Pediatric Dental Patients: A Split-Mouth Randomized Clinical Trial

Local anesthetic injections are usually the main reason for fear and anxiety during dental treatment. Pain management is a critical aspect of pediatric dental care. Fear associated with seeing and experiencing needle penetration, sensation of swelling soft tissues and prolonged numbness as well as allergic reactions to the anesthetic fluid, are the most common factors causing patients and dental clinicians to experience anxiety regarding the use of infiltration local anesthesia. Exploring new alternative and a traumatic method will help improving the quality of care in pediatric dentistry.

Consequently, there is a constant search for new techniques looking to avoid the invasive and often painful nature of the anaesthetic injection required for dental treatments, making it a more pleasant and less distressing experience for patients.

Even though there are no techniques available that can totally replace conventional local anaesthesia, some alternatives have been developed that are effective in a limited range of procedures. In 1997, a new method for the administration of anaesthetics was launched: the computer- controlled local anaesthesia delivery system (CCLADS). After

2006, the single tooth anaesthesia system (STA) (Milestone Scientific, Inc. Livingston, NJ, USA) was also introduced.

Currently, one of the most discouraging aspects for many patients undergoing dental procedures is the administration of anaesthesia. Consequently, there is a constant search for new techniques to avoid the invasive and painful nature of the injection. A new, cableless, motorised syringe system (Dentapen®) has recently been developed, standing out for its convenience and ease of use. The slow injection of anaesthetics at low pressure appears to reduce pain and discomfort during dental anaesthesia, and that currently does not require specific training. It has several injection settings, allowing it to be held like a syringe or pen, and is compatible with all anaesthetic needles and cartridges from all brands with an accurate control of flow and pressure of the injection can therefore mitigate the pain experienced by these patients.
