Summary
Higher water temperatures may damage the color and surface roughness of some soft denture lining materials. Denture cleanser effectiveness and material integrity are affected by heat.
Area of Science:
- Dental Materials Science
- Prosthodontics
Background:
- Soft lining materials are crucial for denture comfort and stability.
- Denture cleansers are used to maintain hygiene, but their interaction with lining materials requires investigation.
Purpose of the Study:
- To assess the impact of water temperature and denture cleansers on soft lining material properties.
- To evaluate color and surface roughness changes in permanent and temporary soft lining materials.
Main Methods:
- Tested five soft lining materials (two silicone, three acrylic resin-based) with four denture cleansers.
- Evaluated specimens at recommended (55°C) and higher (80°C) water temperatures.
- Measured color using a colorimeter and surface roughness with a profilometer.
Main Results:
- Elevated water temperatures in denture cleansers altered the color of some soft lining materials.
- Increased surface roughness was observed on certain soft lining materials when exposed to higher temperatures.
Conclusions:
- Water temperature significantly influences the color and surface integrity of soft denture lining materials.
- Careful selection of denture cleansers and temperature is recommended to preserve material properties.

01:14Assessing Body Temperature - Oral
Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...

01:23Salivary Glands and Saliva
The salivary glands, of which there are three pairs known as the parotid, submandibular, and sublingual glands, play a crucial role in maintaining oral health and initiating the digestive process. Positioned near the ears, beneath the masseter muscle, the parotid glands secrete saliva into the oral cavity through the parotid duct of Stensen. Meanwhile, the submandibular glands, located on the floor of the mouth, secrete saliva through channels named submandibular ducts. The sublingual glands,...
01:29Suctioning the Nasopharyngeal Airway
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

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.

01:18Detergent Purification of Membrane Proteins
Detergents are used to purify the integral proteins of the membrane. The hydrophobic portion of the detergent can replace membrane phospholipids while solubilizing the membrane proteins. When detergent monomers reach a specific concentration in a solution called critical micelle concentration (CMC), they form micelles. Above CMC, the concentration of the detergent monomers remains in equilibrium with the micelle. The number of detergent monomers present in the CMC varies for each detergent, and...
