Summary
Rotary instruments effectively smooth root surfaces after root planing, outperforming Gracey curets and ultrasonic tips. However, their use is more time-consuming in clinical practice.
Area of Science:
- Periodontology
- Biomaterials Science
- Dental Instrumentation
Background:
- Root planing is crucial for periodontal disease treatment.
- Instrument selection impacts root surface smoothness and integrity.
- Evaluating different instruments for root planing efficacy is essential.
Purpose of the Study:
- To compare root surface characteristics after root planing using hand and power-driven instruments.
- To assess the effectiveness of Gracey curettes, ultrasonic tips, and rotary burs in root planing.
- To evaluate the time efficiency and surface roughness achieved by different root planing instruments.
Main Methods:
- Twenty single-rooted teeth were used, with 18 divided into three groups for instrumentation.
- Instruments used: Gracey curette, ultrasonic tip, and rotary bur.
- Measured parameters: time for scaling and root planing, and root surface roughness using the Roughness and Loss of Tooth Substance Index (RLTSI).
Main Results:
- Rotary instruments yielded the lowest mean RLTSI scores (0.667), indicating smoother surfaces.
- Gracey curettes had a mean RLTSI of 2.5, and ultrasonic tips had 2.0.
- Time spent: Gracey curette (42.50s), ultrasonic tip (35.83s), and rotary bur (54.50s).
Conclusions:
- All tested instruments effectively debride the root surface.
- Rotary instruments produce the smoothest root surfaces.
- Rotary instruments are more time-consuming, potentially limiting clinical application.

01:07Scanning Electron Microscopy
A scanning electron microscope (SEM) is used to study the surface features of a sample by using an electron beam that scans the sample surface in a two-dimensional manner. Typically, areas between ~1 centimeter to 5 micrometers in width can be imaged. SEM can be used to image bacteria, viruses, tissues as well as larger samples like insects. Conventional SEM gives a magnification ranging from 20X to 30,000X and spatial resolution of 50 to 100 nanometers.

01:22Overview of Microscopy Techniques
The early pioneers of microscopy opened a window into the invisible world of microorganisms. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes that leveraged nonvisible light, such as fluorescence microscopy that uses an ultraviolet light source and electron microscopy that uses short-wavelength electron beams. These advances significantly improved magnification, image resolution, and contrast. By comparison, the...
