Comparison of Direct Restorative Dental Materials
Our topics will discuss some dental fillings properties
AMALGAM
,COMPOSITES
GLASS IONOMERS
Each material in part
We will discuss the following : General Description, Principal Uses, Leakage and Recurrent Decay, Clinical Considerations,
Resistance to Wear, Resistance to Fracture, Post Placement Sensitivity, Esthetics,
Relative Cost to Patient and finally Average Number of Visits To Complete
FIRST PART
AMALGAM
General Description: A mixture of mercury and silver alloy powder that forms a hard solid metal filling. Self-hardening at mouth temperature
Principal Uses: Dental fillings and heavily loaded back tooth restorations
Leakage and Recurrent Decay: Leakage is moderate, but recurrent decay is no more prevalent than other materials
Clinical Considerations: Tolerant to a wide range of clinical placement conditions, moderately tolerant to the presence of moisture during placement
Resistance to Wear: Highly resistant to wear
Resistance to Fracture: Brittle, subject to chipping on filling edges, but good bulk strength in larger high- load restorations
Post-Placement Sensitivity: Early sensitivity to hot and cold possible
Esthetics: Silver or gray metallic color does not mimic tooth color
Relative Cost to Patient: Generally lower; actual cost of fillings depends on their size
Average Number of Visits To Complete: One
In the end, I thank you and wish you interest
Waited for the second part about COMPOSITE
