The purpose of the study is to use Allium sativum oil and Turmeric gel as non-vital Pulpotomy medicaments in primary teeth by evaluating their antibacterial effect against Streptococcus mutans and Lactobacillus acidophilus.

It is hypothesized that there is no difference in the antibacterial effect of Allium sativum oil and Turmeric gel when used as non-vital Pulpotomy medicaments.

It is a multi-arm parallel Randomized Controlled Trial in which forty patients aged between 4 to 8 years, each containing at-least one non-vital primary molar, will be selected and randomly divided into Group A (Allium sativum oil) and Group B (Turmeric gel). Non-vital Pulpotomy will be performed by removing the coronal necrotic pulp. Sterile paper point will be dipped in the root canals and taken to the laboratory. Cotton pellets soaked in the respective medicaments will be placed over the root canal orifices and filled temporarily. Patients will be recalled after one week. Samples will be again taken, and tooth restored. Comparison between bacterial count at baseline and after one week of treatment will be made and expressed as Colony-Forming Units/ml (CFU/ml).

Inclusion Criteria:

1. Cooperation of patients and consent of parents.
2. Patients with ASA classification I and II (mild to moderate systemic disease).
3. Non-traumatic extensively carious hence restorable primary molars.
4. No history of antibiotic use for 2 weeks.
5. Presence of following clinical signs or symptoms suggestive of nonvital tooth such as tenderness on percussion, non-responsive to cold test, periapical/furcal radiolucency, localized gingival/mucosal soreness/ redness/ swelling, and/or slight mobility-grade I.

Exclusion Criteria:

1. History of allergy to anesthetics and latex.
2. Radiographic evidence of pulpal floor opening into the furcation area
3. More than half of the roots resorbed.
