Abstract
Background: Injection of local anesthesia during dental procedures can induce metabolic changes. The purpose of this study is to evaluate the changes of blood glucose serum level after injection of lidocaein with vasoconstrictor during Tooth Extraction
Materials and Methods: In this clinical trial study, we enrolled 60 patients. We extracted mandibular teeth by using inferior alveolar nerve block. We took a finger blood sample test from each enrolled patient immediately before and 10 minutes after local anesthesia. Anesthetic solution (1.8 ml carpule) contained lidocaine and 1:80,000 epinephrine. It was injected through inferior alveolar nerve after negative aspiration. Only one carpule injected into all patients. This study is approved by ethics committee of the research center of Azad University of Medical Sciences
Results: Mean age in our study was 39.54 ± 15 years old. 35 patients were male and 25 were female. The blood glucose serum level was 111.6 ± 25.47 mg/dl before local anesthesia and 115.3 ± 24.39 mg/dl after tooth extraction (P = 0.418). 11 female patient’s and 4 male patients had blood glucose level reduction after injection. There was a significant difference between groups (P = 0.01).
Conclusion: according to our findings and previous reports, using local anesthesia during teeth extraction doesn’t induce hypoglycemia and it could increase the blood glucose serum level in individuals.

Primary Outcomes
Primary Outcomes (end points)
We took a finger blood sample immediately before and 10 minutes after local anesthesia. We used a glucometer (Accu Check Active, model GC, made in Germany) to measured blood glucose samples.

Experimental Design
Experimental Design
We include all adult individuals how referred to our department for mandibular teeth extractions and we exclude patients how underwent teeth extractions both in mandible and maxilla, known history of diabetes, infection or any contraindications for using epinephrine. Our local anesthesia solution was (1.8 ml carpule) contained lidocaein and 1:80000 epinephrines and it was injected in 1 minute through inferior alveolar nerve block after negative aspiration. Only one carpule injected in all patients.
