About this trial

This in-vivo study aim to evaluate effect of different irrigation activating techniques on Irrigant Penetration Depth and Microbial Reduction in root Canals

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

• Asymptomatic vital/non vital teeth requiring root canal treatment.

Teeth with sound periodontal apparatus.

Teeth without pus or inflammatory exudates draining through the canal.

Teeth without anatomic variations.

Disqualifiers

• Patients with any systemic diseases.

Pregnant or lactating patients.

Immunocompromised patients.

Apparently thin roots in which apical preparation with #40 or #50 file would be overzealous.

Treatments tested in this trial

Group1: A matching gutta-percha master cones will be used in up and down motion 2mm amplitude at a frequency of 100 strokes during approximately 1 min in each prepared canal.
Other intervention
The first microbial sample (S1) will be taken from the root canal immediately after access cavity preparation and before chemomechanical preparation.Samples will be subjected to bacterial viable count using blood agar. After complete chemomechanical preparation, a second microbial samble (S2) will be taken and managed the same way as S1.After irrigation activation protocol by matching gutta percha master cone , S3 will be collected from each root canal and managed as S1, S2 to evaluate effect of activation techniques on microbial reduction ,canals will be dried with a matching paper point then 1 mL of Iohexol (omnipaque) contrast media will be injected 2mL shorter than WL and activated by a matching gutta percha master cone , a digital radiographic image will be obtained for each tooth with the same angulation as that for WL and then the distance between WL and maximum irrigant penetration will be measured and recorded using SIDEXIS-XG software.
Group2: XP-endo Finisher activation: The XP-endo Finisher instrument will be used in continuous rotation for 1 mintute

Group 3:EasyClean system activation : EC instrument coupled to the countrangle handpiece and operated with a micromotor at approximately 20,000 rotations per minute in continuous rotation.
Other intervention
after access cavity preparation and before chemomechanical preparation.Samples will be subjected to bacterial viable count using blood agar. After complete chemomechanical preparation, a second microbial samble (S2) will be taken and managed the same way as S1.After irrigation activation protocol by EasyClean system activation , S3 will be collected from each root canal and managed as S1, S2 to evaluate effect of activation techniques on microbial reduction ,canals will be dried with a matching paper point then 1 mL of Iohexol (omnipaque) contrast media will be injected 2mL shorter than WL and activated by a matching gutta percha master cone , a digital radiographic image will be obtained for each tooth with the same angulation as that for WL and then the distance between WL and maximum irrigant penetration will be measured and recorded using SIDEXIS-XG software.
