Summary
Chlorhexidine cavity disinfectants and agents show antimicrobial effects. While disinfectants didn't impact composite bond strength, mouthrinses and antiseptics reduced it, with Savlex being the most effective antibacterial agent.
Area of Science:
- Dental Materials Science
- Antimicrobial Agents
- Oral Microbiology
Background:
- Chlorhexidine is a widely used antimicrobial agent in dentistry.
- Its application in cavity disinfectants and other forms (mouthrinses, antiseptics) necessitates understanding its efficacy and potential impact on restorative procedures.
- Composite resin restorations rely on strong dentin bonding for longevity.
Purpose of the Study:
- To compare the antimicrobial efficacy of chlorhexidine-containing cavity disinfectants against other chlorhexidine agents.
- To evaluate the effect of these agents on the shear bond strength of composite resins to dentin.
- To identify the most effective antimicrobial agent among the tested solutions.
Main Methods:
- Agar well diffusion method was employed to assess antimicrobial activity against Streptococcus mutans, Lactobacillus acidophilus, and Candida albicans.
- Shear bond strength testing was performed on composite resin bonded to dentin after application of different chlorhexidine agents.
- Statistical analysis (p-values) was used to determine significant differences.
Main Results:
- All tested chlorhexidine solutions exhibited antimicrobial effects against the selected microorganisms.
- Savlex demonstrated the highest antimicrobial efficacy against all tested microorganisms.
- Cavity disinfectants did not significantly affect composite bond strength compared to the control.
- Mouthrinse and antiseptic formulations significantly decreased shear bond strength compared to the control group.
Conclusions:
- Chlorhexidine cavity disinfectants possess antimicrobial properties without compromising composite bond strength.
- Certain chlorhexidine mouthrinses and antiseptics can negatively impact dentin bond strength, potentially affecting restoration integrity.
- Savlex emerges as a highly effective antimicrobial agent for oral applications.

01:23Hand hygiene
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.

01:27Chemical Agents for Microbial Control
Chemicals play important roles in controlling microbial growth by targeting microbial structures and functions as sanitizers, antiseptics, disinfectants, and sterilants.Alcohols are commonly used sanitizers, effectively disrupting lipid membranes, which compromises cell integrity. They are also used as antiseptics and disinfectants due to their rapid action and versatility.Phenols and their derivatives phenolics , known for denaturing proteins and disrupting cell membranes, are particularly...
01:30Cleaning, Sterilization, and Disinfection
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...

01:28Antimicrobial Effectiveness
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...
01:19Masking and Demasking Agents
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on the metal...

01:23Local Anesthetics: Common Agents and Their Applications
Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...
