Teeth

1.7K
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Impact of Groups on Groups

238
Social psychologists analyze how groups influence one another, shaping social structures and interactions through both cooperation and competition. These dynamics manifest in various ways, ranging from economic partnerships to intergroup conflicts that shape societal structures and perceptions.Cooperation and Competition in Intergroup RelationsIntergroup relationships vary across contexts, sometimes fostering cooperation and mutual benefit while at other times leading to conflict and...

Impact01:30

Impact

487
Impact occurs when two bodies collide, leading to the application of impulsive forces between them. Analyzing impact mechanics involves considering two colliding particles moving along a line known as the line of impact, which passes through their centers and is perpendicular to the contact plane.
When particles with different initial velocities collide, they induce deformation by applying equal and opposite impulses. At the point of maximum deformation, the particles move together with...

Impact Loading01:19

Impact Loading

685
Impact loading occurs when a moving object collides with a stationary structure, such as a rod with a uniform cross-sectional area fixed at one end. Under these conditions, the rod absorbs the kinetic energy from the striking object, leading to deformation and subsequent stress development. As the rod returns to its original position and reaches maximum stress, the absorbed energy, initially manifested as kinetic energy, transforms entirely into strain energy.
In cases of elastic deformation,...

Types of Impact

1.0K
Impacts can be classified in various forms, primarily under two subgroups: central impact and oblique impact. A central impact occurs when two objects collide head-on, possessing opposite velocities aligned along the line of impact. Conversely, an oblique impact occurs when two objects collide at an angle, resulting in a modification of both direction and velocity.
The coefficient of restitution is a metric for understanding the dynamics of impacts. It quantifies the ratio of relative velocity...

Impact: Problem Solving

447
In an experiment conducted during a Mars mission, a rover propels a projectile with an initial velocity, and the projectile rebounds after colliding with the Martian surface. To ascertain the maximum height attained by the projectile after this collision, the known restitution coefficient and acceleration due to gravity are employed.
By designating the launch point as the origin and utilizing kinematic equations, the vertical component of the projectile's velocity at the point of impact is...

Summary

Impacted teeth are common, found in over a third of patients. Cone beam computed tomography (CBCT) reveals these impacted teeth often cause pathologies like bone loss and root resorption.

Area of Science:

  • Dentistry
  • Oral Radiology

Background:

  • Impacted teeth are a frequent clinical finding.
  • Pathologies associated with impacted teeth can lead to significant dental issues.

Purpose of the Study:

  • To determine the incidence of impacted teeth.
  • To assess the frequency of pathologies caused by impacted teeth using cone beam computed tomography (CBCT).

Main Methods:

  • Retrospective analysis of 608 cone beam computed tomography (CBCT) scans.
  • Classification of impacted teeth by type (incisor, canine, premolar, molar, third molar, supernumerary).
  • Categorization of pathologies as cysts/tumors, tooth decay, root resorptions, or periodontal bone loss.

Main Results:

  • Impacted teeth were detected in 34.37% of patients.
  • Third molars were the most frequent impacted teeth (39.9%), followed by canines (29.4%).
  • Approximately 63.7% of impacted teeth caused pathology, most commonly periodontal bone loss (44.4%) and root resorption (33.3%).

Conclusions:

  • Impacted teeth are prevalent and frequently lead to pathologies.
  • Cone beam computed tomography (CBCT) is effective for evaluating impacted teeth.
  • Individual assessment of impacted teeth is crucial for management decisions.
