Summary
Rotary (ProTaper Next) and reciprocating (Wave One Gold) root canal treatments effectively reduced bacteria in teeth with apical periodontitis. However, neither technique completely eradicated all bacteria in this single-visit study.
Area of Science:
- Endodontics
- Microbiology
- Dental Materials
Background:
- Apical periodontitis is often caused by root canal bacterial infections.
- Single-visit root canal treatment aims for efficient bacterial elimination.
- Rotary and reciprocating instrumentation offer different biomechanical approaches.
Purpose of the Study:
- To compare the antibacterial effectiveness of ProTaper Next (PTN) and Wave One Gold (WOG) instrumentation techniques.
- To evaluate bacterial reduction in root canals during single-visit root canal treatment for apical periodontitis.
Main Methods:
- Forty patients with apical periodontitis were randomized to PTN or WOG groups.
- Microbiological samples were collected pre-instrumentation, post-instrumentation, and post-final irrigation.
- Bacterial quantification (CFUs) and identification (MALDI-TOF MS) were performed.
Main Results:
- Both PTN and WOG significantly reduced bacterial load (p<0.001).
- No statistically significant difference in antibacterial efficacy was observed between the two techniques (p>0.05).
- 55 aerobic and anaerobic bacterial species were identified.
Conclusions:
- Both PTN and WOG are highly effective in reducing bacteria in necrotic root canals.
- Complete bacterial eradication was not achieved with either technique in this study.
- Further research may explore adjunctive disinfection protocols.

2
The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

19.6K
As used in a healthcare facility, sterilization destroys all microorganisms through physical or chemical methods. The physical method includes steam, dry heat, boiling water, and radiation.
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...

2
Radiation and filtration are essential tools for microbial control, targeting microorganisms through distinct mechanisms. Radiation eliminates microbes by damaging their DNA, either killing them or inhibiting their growth. Based on wavelength, radiation is classified into two types: nonionizing and ionizing radiation.Non-ionizing radiation, such as UV radiation (200–400 nm), is absorbed by DNA, causing defects that effectively disinfect surfaces, air, and water, including safety cabinets.

Aseptic techniques prevent contamination, ensure experimental accuracy, and protect researchers and microbial cultures. These techniques are essential in clinical, industrial, and research settings where sterility is required.Maintaining Sterility in Laboratory PracticesScientists maintain sterility by sterilizing tools with heat or chemicals, disinfecting work surfaces, and handling cultures in controlled environments. Working near an open flame or within a laminar flow hood reduces the risk...

Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
