[The polishing of composite resins, a preliminary study using laser reflection]
Journal (Canadian Dental Association)
|July 1, 1989
Summary
This pilot study explored laser analysis of composite resin surfaces. While not statistically valid, the findings suggest this method can assess surface treatments effectively.
Area of Science:
- Materials Science
- Dental Materials
Background:
- Composite resins are widely used in restorative dentistry.
- Surface treatments are critical for resin performance and longevity.
- Evaluating the efficacy of surface treatments is essential.
Purpose of the Study:
- To investigate a novel method for analyzing the surface characteristics of composite resins.
- To assess the impact of various surface treatments on composite resin surfaces.
Main Methods:
- Four types of composite resins were subjected to twelve distinct surface treatments.
- A Helium-Neon laser was employed to illuminate the treated surfaces.
- Photographs of reflected laser beams were captured and analyzed based on light diffusion patterns.
Main Results:
- The study visually ranked the reflected laser patterns in order of increasing diffusion.
- Preliminary data suggest distinct diffusion patterns correlating with different surface treatments.
- The method showed potential in differentiating surface modifications.
Conclusions:
- The laser-based surface analysis technique shows promise as a useful tool in materials science and dentistry.
- Further statistically validated studies are warranted to confirm the efficacy of this method for evaluating composite resin surface treatments.

Reflective Property of Parabolas
285
A parabola is a basic type of conic section that results from the intersection of a plane with a double-napped cone in a direction parallel to one of the cone's sides. This U-shaped curve has a distinctive reflective property: all incoming rays parallel to its axis of symmetry are directed toward a single point, known as the focus. This property is widely utilized in optical and communication technologies that require precise signal concentration.In analytic geometry, a parabola is defined as...

Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...

The Sense of Self: Reflected Self-Appraisal and Social Comparison
56.1K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Reflection of Waves
4.7K
When a wave travels from one medium to another, it gets reflected at the boundary of the second medium. A common example of this is when a person yells at a distance from a cliff and hears the echo of their voice. The sound waves (longitudinal waves) traveling in the air are reflected from the bounding cliff. Similarly, flipping one end of a string whose other end is tied to a wall causes a pulse (transverse wave) to travel through the string, which gets reflected upon reaching the wall. In...

Composite Bodies
1.4K
A composite body is a body made up of multiple parts, connected to form a larger, unified object. Each part has its own weight and center of gravity, which must be considered to determine the center of gravity of the composite body. In cases where the density or specific weight is constant, the center of gravity coincides with the centroid.
Composite bodies have widespread applications in mechanical engineering, from automobiles to aircraft to rockets. For example, an automobile wheel comprises...

Composition of Blood
12.5K
The blood in our bodies comprises three major components: blood plasma, formed elements, and the extracellular matrix. Blood plasma is a yellowish fluid that constitutes 55% of the total blood volume. It is primarily made up of water and essential substances such as electrolytes and proteins. Blood plasma serves as a medium for transporting blood cells and also contains nutrients, enzymes, hormones, antibodies, and gases.
Formed elements constitute the remaining 45% of the blood volume. These...
