Evaluate and compare the disinfecting efficacy of two supplementary antimicrobial protocols in teeth with apical periodontitis
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 *…
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 * Teeth with extensive coronal destruction * Teeth with previous endodontic treatment * Symptomatic apical periodontitis * Teeth with periodo…
Desinfection protocol with (LAI): Er,Cr:YSGG laser (2780 nm) delivered with a radial-firing tip.
Endocator: Measures ATP levels (Endoscore and RLU) to rapidly assess bacterial load in less than one minute.
