Student to student administration of dental local anesthesia training has possible risk to cause nerve and muscle trauma. This research aims to create the newest technology for dental local anesthesia training in mandibular region using electrolyte switch and capacitive sensor system. The device facilitates user to inject the fluid at the injection site, knows the accuracy of the dosage according to clinical standard operating procedure and knows the accuracy of the injection site, so the student can feel a real sensation in anesthetic training even without using human being as their subject. In this research, there were 3 methods, first was technique of prototype formation, second was sensor accuracy test and the last was data analysis. The result of this research was the creation of the newest technology of smart wet injection phantom with electrolyte switch and capacitive sensor system. Electrolyte switch could detect the accuracy of the injected fluid, using voltaic cell principle to make the switch-like system at each fluid level with electrode and electrolyte solution as the component of the switch. The capacitive sensor could detect accuracy of the injection site and placed in the injection area for inferior alveolar nerve, buccal nerve and lingual nerve. Accuracy of capacitive sensor and electrolyte switch system were above 80% and 90%, so it could be interpreted that the sensors had good accuracy. From this study, we conclude that the combination of electrolyte switch and capacitive sensor system can produce smart wet injection phantom which has good sensor accuracy so it can help dental student to practice local anesthesia in mandibular region accurately.
