Biophysics Applications In Dentistry

Biophysics Applications In Dentistry

Dental material science is a basic science that deals with the physical, mechanical, and biological properties of dental materials.

Aims of Dental Material Science:

• To present the basic chemical and physical properties of dental materials.
• To provide sound educational background so that the practice of dentistry emerges from an art into an empirical status of science as more information through further research becomes available.
• Intended to bridge the gap between knowledge obtained in basic courses in material science, chemistry, physics, and dental operatory
• To generate curiosity as to why materials react as they do, why manipulation variables should be observed, and how information is largely limited to material per se and to make the profession an exciting experience?
• To provide the dentist with certain criteria of selection that will enable him to discriminate between fact and propaganda with regard to claims of manufacturers.

Objectives of Dental Material Science:

• To understand the evolution and development of the science of dental materials.
• To explain the purpose of the course in dental materials to the person concerned with the profession of dentistry.
• For knowledge of the physical and chemical properties of dental materials.
• For knowledge of biochemical requirements of a physical restorative procedure.
• An intelligent compromise of the conflicting as well as coordinating factors into the desired end results.
• To lay down standards or specifications of various dental materials to guide the manufacturers as well as to help the profession.
• To search for new and better materials which may answer our requirements with greater satisfaction.
• To understand and evaluate the claims made by manufacturers of dental materials.

Criteria for Selection of Restorative Materials in Different Patients:

The selection process is based on consideration of the advantages and disadvantages of each material and will take into account the different requirements of each practitioner according to his/ her skill level, type of practice, cost factors, and other criteria.

• Analysis: Select the material for a particular situation. Incorrect decisions may lead to failure of restoration or appliance.
• Requirements: List the requirement for a material to meet the need for that situation.
• Available materials: The properties of the available materials are compared with requirements at two levels. Previous experience with materials in similar circumstances will be a major factor that influences selection. Newly developed products are to be used to give better results for the same situation to be followed.
• Choice of material: After comparing the properties of available material with the requirements, the final choice of material brand is a matter of personal preference on the part of the dentist. Factors such as ease of handling, availability, and cost may play a part at this stage of the selection process.
