About this study

Study Design:

The mouth will be split in half using a split mouth study. The lower anterior teeth will be injected with a conventional local anesthetic syringe on one side, and the patient will be injected with an electronic anesthetic syringe on the other side.

The study will be conducted on a sample of volunteers aged 18 to 30 years at the Faculty of Dentistry at Al-Andalus University.

The objectives and procedure will be explained to each group of patients, and informed consent will be obtained from each patient to accept the research procedures.

A 2% non-vasoconstrictor lidocaine local anesthetic will be used for all patients.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

". Age ranged from 20 to 30 years , no menstrual cycle, The participants were not allergic to local anesthetics, had not used medication that would alter pain perception, none of them had not ever experienced Smartject injection before, and none of them were alcoholics or smokers, The participants were not allergic to local anesthetics.

Exclusion criteria

allergic to local anesthetics ,females during menstural cycle ,bad oral care.

Treatment and study plan

Experimental group: Electronic syringe therapeutic intervention arm

Drug

Intraoral Mental nerve block on both sides (experimental and control). A Carpule syringe with an aspiration and short needles 30G were used on the control side, while Smartject was used on the experimental side

Other names: anesthesia pen x

control group: therapeutic intervention using a traditional syringe

Drug

During the appointment, the subjects randomly received 1.8 ml of 2% plain lidocaine for the Intraoral Mental nerve block on both sides (experimental and control). A Carpule syringe with an aspiration and short needles 30G were used on the control side

Other names: surgimax

Primary outcomes

  1. Onset time

    Time frame: 2 month

    was considered as the period between the end of the injection and the first subsequent Onset time was considered as the period between the end of the injection and the first subsequent readings without response. After this period, the tooth was tested every 10 minutes until readings returned to the baseline threshold. Each subject was asked to record the time of return to normal sensation in the lower lip

Secondary outcomes

  1. Visual Analogue Scale (VAS)

    Time frame: 2 month

    VAS uses a straight horizontal line of extent measuring 10 cm. The ends state the maximum limit of pain orientated from the best (right) to the worst (left) so that the patient can indicate the intensity of the pain (0-100). The intensity of pain is made by measuring the dimension from "no pain" to "very severe pain" based on the patient's signs

Other outcomes

  1. duration of the anesthesia

    Time frame: 2 month

    was asked to record the time of return to normal sensation in the lower lip
