About

Background: Articaine hydrochloride has steadily grown in popularity, and studies have shown that articaine hydrochloride performs better than lidocaine due to an enhanced anes-thetic efficacy. The most common technique to anesthetize mandibular primary teeth is in-ferior alveolar nerve block (IANB) which induces a relatively sustained anesthesia and in turn may potentially traumatize soft-tissues. Therefore, the need of having an alternative technique of anesthesia with a shorter term but the same efficacy is reasonable.

Aim: Evaluating The effectiveness of Articaine infiltration versus conventional inferior al-veolar nerve block in anesthetizing the second primary mandibular molars during pulpoto-my procedure.

Materials and Methods: The study will be two-arm randomized controlled clinical trial, parallel design and it will be setup and reported according the CONSORT guidelines. A total of 52 healthy children aged 5-6 years, will be selected from Pediatric Dentistry and Dental Public Health Department, Faculty of Dentistry, Alexandria University, Egypt. Children will be selected with scores 3 or 4 according to Frankl behavioral rating scale. Each child selected will have at least one mandibular second primary molar that is indicat-ed for pulpotomy. Written informed consent will be obtained from guardian. Participants will be randomly and equally allocated to one of the two arms into two groups according to the technique of anesthesia that will be used.

Group I (Experimental group n =26) assigned to articaine infiltration anesthesia, while group II (Control group n = 26) assigned to the conventional IANB injection articaine.

Pain will be assessed by three diferent methods: physiological method using the Heart rate as vital parameter of pain, and will be recorded at base line, during injection, pulpotomy and stainless steel crown (SSC) preparation. Objective method using Sensory, Eye, Motor (SEM) scale, and subjective method where the pain will be evaluated by asking the child to express his experience using a modified face scale from the Maunuksela scale
