Study Notes

Delivery of Complete Dentures to the Patient

Patients receiving complete dentures should be given clear instructions on their use and aftercare.
Three groups evaluate complete dentures; dentist, patient, and patient's relatives/friends.
Dentist evaluations should be sincere and honest. Any mistakes should be corrected immediately.

Patient Evaluations

Patient evaluations, focusing on the satisfaction with the try-in stage.
Patient evaluation has two stages: delivery and post-delivery stages.
Post-delivery includes following up with patients on problems or issues.

Recommendations for Patients Starting to Use New Dentures

New dentures may feel foreign in the beginning and lead to a sensation of fullness in the lips and cheeks.
Patients should practice speaking with dentures and practice reading aloud.
Initially, eat soft foods in small pieces. Chewing on both sides improves balance.

Denture Cleaning Agents and Methods

Dentures should be cleaned using various methods and materials to remove stains and microorganisms.
Mechanical methods include brushing with suitable brushes, water and toothpaste, use of ultrasonic devices, and use of microwave ovens.
Chemical methods include alkaline peroxides, alkaline hypochlorites, diluted acids, disinfectants, and enzymes.

Can Dentures Get Dirty?

The porous structure of the base materials, stippling on the gum line, spaces between teeth, retentive elements, micro scratches, and pits during finishing and polishing lead to denture contamination.
These factors allow microorganisms to settle and proliferate.

Disinfection and Sterilization

Disinfection means removing or inactivating harmful microorganisms.
Viruses and spores may not be killed.
Sterilization destroys bacteria, fungi, vegetative forms, and resistant viruses.
Sterilization can lead to deformation in acrylic; thus, disinfection is preferred.

Denture Contamination Inside the Mouth

Denture contamination occurs in three stages:
1. Mucins and food accumulate.
2. If not removed, they adhere tightly to the denture base, leading to plaque.
3. Organic matrix undergoes calcification until it becomes fully calcified. This accumulation then harbors pathogenic microorganisms, leading to stomatitis.

Denture Contamination Outside the Mouth

Tools, materials, water, and personnel hands and skin can contaminate dentures.
Contaminated dentures can transmit microorganisms to the dentist, dental assistant, or laboratory during handling.
The reverse process is also true.

Ideal Characteristics of Denture Cleaners

Bactericidal and fungicidal properties.
Compatible with denture base materials.
Non-toxic to the user.
Relatively inexpensive.
Easy to use.

Cleaning Methods

Mechanical methods include brushing, ultrasonic devices, and microwave ovens.
Chemical methods include alkaline peroxides, alkaline hypochlorites, diluted acids, disinfectants, and enzymes.

Brushing

Use regular, specifically made denture brushes.
Use water and soap or toothpaste (with caution).
Avoid hard bristles, non-dissolving calcium carbonate containing pastes, as these can cause wear.

Use of Ultrasonic Devices

Ultrasonic devices alone are not sufficient, but they are effective when combined with disinfectants.
They do not damage polished surfaces.
Recommended for patients with disabilities.

Use of Microwave Ovens

Microwave energy provides sterilization but does not remove dead microorganisms and their products.

Alkaline Peroxides

Powder or effervescent tablets; oxygen bubbles create a micro-mechanical effect on lightly adhered dirt.
Effective on recently formed stains and plaque.
Dentures should remain in the solution for several hours or overnight.

Alkaline Hypochlorites

Removes discoloration.
Dissolves mucin layers and other organic structures- exhibiting bactericidal and fungicidal effects -
Does not dissolve tartar, but prevents further tartar formation.
Effective on tea stains but is harmful to hands and clothes, and causes discoloration in metal.

Diluted Acids

Can remove stains resistant to peroxide-based cleansers.
Harmful to clothing, skin, and eyes, so careful use is necessary.
Not recommended for dentures containing metal.

Disinfectants

Solutions that remove or inactivate harmful microorganisms.
Potassium permanganate, glutaraldehyde, chlorine dioxide, and chlorhexidine gluconate.
Can cause roughness and a decrease in the hardness of acrylic when used for prolonged periods.

Enzymes

Solutions containing enzymes like papain, mutase, protease, and amylase.
Effective in removing organic substances.
EDTA can be added to the solution for inorganic component removal.

Conclusion

Tools should be sterilized.
Newly made dentures should be soaked in a disinfectant solution before delivery.
Dentures to be repaired should be placed in a disinfectant solution before and after repair.

Acrylic or Metal Base Prosthetics

Always rinse with water after meals.
Brush with a soft brush, soap, and cold water.
Soak the dentures in a commercial cleaning tablet solution 1-2 times weekly based on contamination level.

Temporary Soft Lining Material

Rinse with water only, do not brush.

Permanent Soft Lining Material

Use a soft brush with soap and water.
Soak in a 1% sodium hypochlorite solution for 20 minutes. Use with caution, as it can be harmful to certain materials.
