Comparison Between Efficiency of Inferior Alveolar Nerve Block and Buccal Infiltration Techniques Using Articaine 4% 1:100000

Buccal Infiltration Technique Compared to Inferior Alveolar Nerve Block Technique for Alleviation of Intraoperative Pain During Pulpal Treatment of Mandibular Primary Molars: A Randomized Controlled Clinical Trial.

This split mouth randomized control trial is designed as to compare the effectiveness of the buccal infiltration technique with the gold standard inferior alveolar nerve block in anesthetizing mandibular second primary molars to undergoing pulpal treatment.

patient will be videotaped during pulpal treatment of their teeth and an accessing pain will be through an objective pain scale (SEM scale), (sound-eye-motor scale).

the patient will be asked to fill in a subjective Wong Baker pain scale for the pain suffered during injecting the local anesthetic agent in both techniques.

A-Inclusion Criteria:

1. first dental visit.
2. cooperative children (rating 4 or 3 based on Frankl behavior scale) aging from 6 to 8 years suffering from one or more deep carious lesions in their primary molars seeking treatment.
3. Restorable molars with stainless steel crowns.

B-Exclusion Criteria:

1. medically compromised patients. uncooperative children (rating 1 or 2 on the Frankl behavior scale)needing special line of treatment through general anesthesia.
2. signs and symptoms of irreversible pulpitis, spontaneous pain, necrosis or any signs or symptoms of any infection.
3. presence of any radiographic signs of abcess, bone loss, internal or external root resorption.
4. parents or guardians who refuse participating in the study.
