Hand hygiene

Hand 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.

Summary

This summary is machine-generated.

Polident denture cleaner effectively sanitizes previously worn dentures, with 8-hour room temperature soaks or 5-minute 65°C soaks being most effective. Microwaving, sonication, and vacuum immersion showed lesser, though still significant, microbial load reduction.

Area of Science:

Oral hygiene and prosthodontics
Microbiology
Infection control

Background:

Limited scientific data exists on effective denture sanitization methods for previously worn prostheses.
Product claims for denture sanitization lack controlled scientific validation.

Purpose of the Study:

To scientifically evaluate denture sanitization procedures for previously worn, contaminated dentures.
To compare the efficacy of various sanitization methods, including Polident, microwaving, sonication, and vacuum immersion.

Main Methods:

Examined 51 previously worn dentures from two US regions using established culturing techniques.
Assessed microbial contamination after treatments with Polident (US/EU formulations), microwaving, sonication, and vacuum immersion.
Statistical analysis using ANOVA and GLM with significance at P < .05.

Main Results:

All Polident treatments significantly reduced microbial loads on dentures.
Optimal Polident efficacy achieved with 8-hour room temperature soaks or 5-minute 65°C soaks.
Microwaving was more effective than sonication or vacuum, but all treatments resulted in sanitization, not sterilization.

Conclusions:

Denture-borne microorganisms are significantly reduced by Polident solution (8 hours at room temp or 5 minutes at 65°C).
Daily use of Polident is crucial for sanitizing worn prostheses.
Microwaving, sonication, and vacuum methods were less effective than optimal Polident use.
