Introduction: This study evaluated the effectiveness of chemomechanical preparation associated with intracanal medication in reducing the total bacterial load of infected root canals in cancer patients undergoing antineoplastic treatment. The prevalence, levels, and response to treatment of Streptococcus and Actinobacteria species were also assessed.
Methods: The root canals of teeth with apical periodontitis from oncological and control patients were treated using rotary instrumentation, 2.
Article Synopsis
- This study developed a method to test disinfection techniques for lateral canals in extracted teeth using an ex vivo model.
- The researchers created lateral canals in mandibular premolars and contaminated them with a bacterial culture to evaluate the effectiveness of different disinfection procedures.
- Results showed that all tested methods significantly reduced bacterial presence in the canals, with no significant differences in effectiveness among the various disinfection techniques used.
Bone infections are still a major problem in surgery. To avoid severe side effects of systemically administered antibiotics, local antibiotic therapy is increasingly being considered. Using a pressure-based method developed in our group, microporous β-TCP ceramics, which had previously been characterized, were loaded with 2% w/v alginate containing 50 mg/mL clindamycin and 10 µg/mL rhBMP-2.

Methods: Mesial roots from extracted mandibular molars with Vertucci class II configuration were anatomically matched based on micro-computed tomography (micro-CT) analyses and distributed into 3 groups (n = 18/group). The canals were contaminated with a mixed bacterial culture for 30 days and then subjected to preparation using 2.
spittlebug nymphs produce a wet foam from anal excrement fluid, covering and protecting themselves against numerous impacts. Foam fluid contact angles on normal (26°) and silanized glass (37°) suggest that the foam wets various substrates, including plant and arthropod surfaces. The pull-off force depends on the hydration state and is higher the more dry the fluid.
