Summary
This study found that increasing the thickness of stabilization splints does not significantly alter the position of mandibular condyles within the temporomandibular joint. Thicker splints do not lead to greater condylar distraction.
Area of Science:
- Dentistry
- Biomechanics
- Orthodontics
Background:
- Stabilization splints are used in dentistry to manage temporomandibular joint (TMJ) disorders.
- Understanding condylar position during splint wear is crucial for treatment efficacy.
Purpose of the Study:
- To investigate the effect of different stabilization splint thicknesses on mandibular condyle position.
- To determine if increased splint height influences condylar displacement within the TMJ.
Main Methods:
- Ten fully dentate participants wore two stabilization splints with varying molar contact heights (1 mm vs. 4 mm).
- Condylar position was tracked using an ultrasound jaw tracking device with six degrees of freedom.
- Linear deviation of condylar position was calculated from Cartesian coordinates.
Main Results:
- The mean linear deviation was 2.04±1.18 mm for the 1 mm splint and 2.32±1.24 mm for the 4 mm splint.
- Statistical analysis (Independent samples T test) showed no significant difference in condylar deviation between the two splint thicknesses.
- No statistically significant change in condylar position was observed with increased splint height.
Conclusions:
- Increasing the thickness of stabilization splints does not significantly alter mandibular condyle positioning in the temporomandibular joint.
- Greater condylar distraction cannot be achieved by using thicker stabilization splints.

Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.

Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

The time response of a linear time-invariant (LTI) system can be divided into transient and steady-state responses. The transient response represents the system's initial reaction to a change in input and diminishes to zero over time. In contrast, the steady-state response is the behavior that persists after the transient effects have faded.
The stability of an LTI system is determined by the roots of its characteristic equation, known as poles. A system is stable if it produces a bounded...

In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.

The serial position effect is a cognitive phenomenon where individuals are more likely to recall the first and last items in a list compared to those in the middle. This effect is divided into the primacy effect and the recency effect. The primacy effect is observed when the initial items in a list are remembered better. This occurs because these items are rehearsed more frequently or receive more elaborative processing, allowing them to be encoded into long-term memory more effectively. For...

In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...
