Summary
This study found that 27.2% of Trinidadian patients had impacted third molars, with mandibular impactions and associated caries being most common. These findings highlight the need for dental screening in the region.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Radiology
- Public Health Dentistry
Background:
- Impacted third molars (wisdom teeth) are a common dental issue.
- Understanding their prevalence and patterns is crucial for dental professionals.
Purpose of the Study:
- To determine the prevalence and patterns of impacted third molars in a Trinidadian population.
- To identify associated pathologies and other impacted teeth.
Main Methods:
- Retrospective analysis of 1500 orthopantomograms (OPGs) from 2008-2019.
- Evaluation of patient demographics, impaction type, level, and associated pathologies.
- Recording of other impacted teeth besides third molars.
Main Results:
- 27.2% of the sample (408/1500) had at least one impacted third molar.
- Mandibular impactions (77.9%) were more frequent than maxillary (22.1%).
- Common pathologies included caries on second molars (49.3%) and third molars (40%).
Conclusions:
- The prevalence of impacted third molars in Trinidad is 27.2%.
- Findings provide insights into impaction patterns and associated pathologies.
- Emphasizes the need for population-based screening by dental professionals.

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...

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...

01:20Imaging Studies for Cardiovascular System III: X-Ray
164
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
