Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current direct pulp capping materials, such as calcium hydroxide and mineral trioxide aggregate (MTA), face issues like high solubility, poor handling characteristics, and limited sealing ability, which can lead to inflammation and inadequate dentin bridge formation, necessitating a more effective solution for protecting and repairing exposed tooth pulp.

Innovation Solution

A method involving the administration of a dental composition containing betamethasone and gentamicin, optionally with Portland cement, followed by coverage with glass ionomer cement to form a calcification, or dentin bridge, over the exposed pulp of a tooth, addressing inflammation and promoting reparative dentin formation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If calcium hydroxide is used for pulp capping, then antibacterial activity and calcium release are improved, but solubility and sealing ability deteriorate

Engineering Contradiction:

Improveantibacterial activityVSAvoidsolubility

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent combines calcium hydroxide with glass ionomer cement to create a composite material that maintains the antibacterial and calcium-releasing properties of calcium hydroxide while adding the sealing ability and reduced solubility of glass ionomer cement. This composite approach resolves the contradiction by integrating materials with complementary properties.

Inventive Principle:

Principle #40Composite materials

2Reliability

If MTA is used for pulp capping, then dentin bridge formation is improved, but setting time and handling characteristics deteriorate

Engineering Contradiction:

Improvedentin bridge formationVSAvoidsetting time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent extracts the beneficial dentin bridge-forming capability from MTA and combines it with glass ionomer cement, which has faster setting time and better handling characteristics. This separation and recombination allows achieving MTA's effectiveness without its drawbacks.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the material composition parameters by formulating a glass ionomer cement-based composition with calcium hydroxide and biocompatible additives, altering the setting time and handling properties while maintaining or enhancing dentin bridge formation capability compared to traditional MTA.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If traditional pulp capping materials are used, then pulp protection is provided, but inflammation reduction and reparative dentin formation are insufficient

Engineering Contradiction:

Improvepulp protectionVSAvoidinflammation

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent introduces biocompatible additives as intermediaries that mediate between the dental material and pulp tissue, reducing inflammatory response and promoting reparative dentin formation. These additives act as biological mediators that enhance the interaction between the material and living tissue.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a composite material system combining glass ionomer cement, calcium hydroxide, and biocompatible additives that work synergistically to provide pulp protection while actively reducing inflammation and stimulating reparative dentin formation, going beyond the capabilities of traditional single-material approaches.

Inventive Principle:

Principle #40Composite materials
