Summary
Dental patch testing (DPT) helps identify allergies to dental materials, particularly metals like nickel. Positive DPT results significantly improve outcomes for dental procedures, guiding treatment effectively.
Area of Science:
- Oral medicine
- Allergology
- Dental materials science
Background:
- Allergic reactions to dental materials in prostheses and implants can cause device dysfunction.
- Identifying and managing these allergies is crucial for successful dental treatments.
Purpose of the Study:
- To evaluate the diagnostic value of the dental patch test (DPT) for dental material allergies.
- To assess the impact of DPT results on the success of subsequent dental procedures.
Main Methods:
- A prospective study involving 382 adult patients with symptoms related to dental materials.
- Administration of a 31-item dental patch test.
- Assessment of clinical outcomes following dental restoration based on DPT results.
Main Results:
- Metals were the most common allergens, with nickel sensitivity at 29.1%.
- Patients with positive DPT results showed significantly higher rates of self-reported allergic diseases and metal allergy.
- Clinical improvement was observed in 82% of patients with positive DPT results versus 54% with negative results.
Conclusions:
- Self-reported metal allergy is a key predictor of allergic reactions to dental devices.
- Dental patch testing is valuable for guiding dental procedures and preventing adverse reactions.
- Pre-procedure screening for metal allergy symptoms is recommended.

Many fundamental cell functions such as muscle contraction and nerve transmission rely on the electrical signals produced by the movement of positively and negatively charged ions across the cell membrane. One competent method to record current flowing across the whole cell or single ion channel is the patch-clamp technique.
In this method, a glass micropipette containing electrolyte solution is tightly sealed against a small portion of the cell membrane. As a result, a patch of the cell...

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
