Study Notes
Course Information
- Textbooks include "Dental Materials" by John M. Power and John C. Wataha, and "Phillip’s Dental Materials" by Kenneth J. Anusavice.
- Assessment consists of quizzes (20 marks total), mid-term (30 marks), and final exam (40 marks, including continuous evaluation).
Course Learning Outcomes
- Identify different types and classifications of dental materials and their indications.
- Understand properties of dental materials including physical, chemical, mechanical behavior, and biocompatibility.
- Describe chemical compositions and setting behaviors of various dental materials.
- Master proper mixing and handling methods for dental materials.
Course Topics
- Introduction to dental materials and their properties.
- Gypsum products, polymers, and impression materials.
- Amalgam and both types of direct tooth-colored restorative materials.
- Principles of bonding, dental wax, casting alloys, and dental ceramics.
Biomaterials
- Defined as non-living materials designed to interact with biological systems, such as cardiovascular implants and dental restorative materials.
Biocompatibility
- Refers to the ability of a material to contact living systems without causing adverse effects.
- Essential traits include non-irritation to oral tissues, non-toxicity, non-allergic nature, and lack of carcinogenic properties.
Biomechanics
- The study of how biological materials interact and deform under environmental stress.
- Dental materials must withstand forces from mastication, occlusion, and temperature changes.
Dental Diseases & Restorative Materials
- Restorative materials prevent or repair damage from dental diseases like caries and periodontal disease or from trauma.
Caries
- Caused by a bacterial biofilm (plaque) that secretes acids leading to enamel and dentin dissolution.
- Carious lesions typically appear in areas where plaque accumulates, such as pits, fissures, and interproximal spaces.
Periodontal Disease
- Affects supporting tissues of teeth, including gingiva, periodontal ligament, cementum, and alveolar bone.
Impact of Trauma, Systemic Disease, and Genetic Disorders
- Trauma can cause fractures or displacement of teeth.
- Restorative materials are used to repair and stabilize damaged teeth.
Classification of Dental Materials
- Preventive dental materials include pit and fissure sealants, fluoride products, and therapeutic agents for decay and gum disease prevention.
- Mouth protectors are utilized to prevent trauma in patients.
