Inclusion criteria
Inclusion criteria: 1. Individuals aged between 19 and 21 years, currently junior dental students engaged in practicing inferior alveolar nerve block, on one another as part of the Professional Development course controlled by maxillofacial surgeons. 2. Every participant had a minimum of two sound lower teeth including the first premolar tooth and the first molar tooth. These teeth were free from bridge, crown, severe caries damage, extensive restoration, advanced periodontal disease, history of trauma, or sensitivity guaranteed by maxillofacial surgeon. 3. Participants were required to report no current pain, be in good health, and not be taking any medication that might affect their perception of pain, as determined through verbal questioning. 4. the outcome measures would encompass at least one of the following: the success of anesthesia, the speed of onset of anesthesia, the duration of anesthesia, and any adverse effects.
Exclusion criteria
Exclusion criteria: 1. Individuals with cardiac disease or other systemic medical issues that impede the administration of local anesthesia. 2. Patients who were prescribed premedication drugs that could potentially impact the assessment before administering anesthesia. 3. Participants with an infection or acute inflammation at the injection site, which reduce the effectiveness of anesthesia or having pain in other teeth. 4. Participants with anatomic variations that can impact an IAN block, such as trismus, bifid mandibular canals, micrognathia, etc. 5. Participants who lack anesthesia will be excluded.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The study assessed the effectiveness of different types of local anesthesia in terms of success, onset, duration of action, and adverse effects for IAN block injections. 4 hr and 24 hr The onset of anesthesia was tracked using a digital timer and tested with 3-0 Nylon monofilament suture material for the light touch sensation test. | — |
