Summary
This systematic review examines prophylactic removal of asymptomatic impacted wisdom teeth and evaluates surgical techniques. Evidence supports informed decisions regarding third molar extraction and potential complications.
Area of Science:
- Oral and Maxillofacial Surgery
- Evidence-Based Dentistry
Background:
- High incidence of impacted wisdom teeth (third molars) in young adults.
- Potential complications include pain, infection, adjacent tooth damage, and bone destruction.
Purpose of the Study:
- To determine if asymptomatic, disease-free impacted wisdom teeth should be removed prophylactically.
- To assess the effects of various surgical methods for impacted wisdom tooth removal.
Main Methods:
- Systematic review of 29 studies (reviews, RCTs, observational studies).
- Searched major databases (Medline, Embase, Cochrane Library) up to August 2006.
- Included harms alerts and GRADE evaluation of evidence quality.
Main Results:
- The review synthesizes evidence on prophylactic extraction efficacy and safety.
- Comparative data on different surgical techniques for wisdom tooth removal is presented.
Conclusions:
- Provides information on the effectiveness and safety of prophylactic wisdom tooth extraction.
- Offers insights into the outcomes of various surgical interventions for impacted third molars.

01:15Teeth
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 and...

01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

01:30Impact
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...
