Official title
Comparison of Different Root Canal Disinfection Protocols for Bacterial Reduction in Teeth With Apical Periodontitis Using Two Analytical Microbiological Methods: a Randomized Clinical Study
Overview
Evaluate and compare the disinfecting efficacy of two supplementary antimicrobial protocols in teeth with apical periodontitis
Detailed description
This study aims to evaluate and compare the disinfecting efficacy of two supplementary antimicrobial protocols in teeth with apical periodontitis: Er,Cr:YSGG laser activated irrigation and ultrasonic activation using a piezoelectric ultrasonic device (Dentsply International Inc., York, PA, USA) and Irrisafe tip (Satelec/Acteon, Merignac, France), comparing the detection of bacteria before and after instrumentation.
Secondary aims are to assess presence of bacteria before and after chemomechanical preparation using two microbiological methods:
* ATP level analysis using the Endocator device * Quantitative PCR (qPCR) for total bacterial quantification.
Interventions
- Device Desinfection device
Desinfection protocol with (LAI): Er,Cr:YSGG laser (2780 nm) delivered with a radial-firing tip. - Device Analytical microbiological methods
Endocator: Measures ATP levels (Endoscore and RLU) to rapidly assess bacterial load in less than one minute.
Primary outcome measures
- Reduction of bacteria in the root canal system [Time frame: Immediately after the irrigation activation procedure, ATP levels will be measured, and qPCR analysis will be performed at the end of the study, once all samples have been collected.]
Eligibility criteria
Inclusion criteria
- Adult patients able to give informed consent and willing/able to comply with study procedures and follow-up.
- Molar teeth indicated for endodontic treatment.
- Teeth with intact pulp-chamber walls (no extensive coronal destruction).
- Necrotic pulp confirmed by pulp testing.
- Clinical and radiographic evidence of asymptomatic apical periodontitis.
Exclusion criteria
- Immature teeth
- Teeth with calcified or obliterated canals

- Symptomatic apical periodontitis
- Teeth with periodontal pockets greater than 4 mm
- Patients who have received systemic antibiotics in the last 3 months
- Patients with a history of diabetes or immune impairment
- Pregnant patients
