Summary
This study found no significant gender differences in tooth size discrepancies (TSD) among Jordanian schoolchildren. Many participants exhibited TSD exceeding normal ranges, indicating potential orthodontic treatment needs.
Area of Science:
- Dentistry
- Orthodontics
- Anthropology
Background:
- Tooth size discrepancies (TSD) can impact orthodontic treatment planning and outcomes.
- Assessing TSD in diverse populations is crucial for understanding variations in dental morphology.
Purpose of the Study:
- To determine tooth size discrepancies in Jordanian schoolchildren.
- To compare tooth size discrepancies between male and female Jordanian schoolchildren.
Main Methods:
- Dental casts from 367 Jordanian schoolchildren (174 males, 193 females) aged 15.5 years were analyzed.
- Anterior and overall Bolton ratios were calculated using digital calipers.
- Independent samples t-test was used to compare gender differences.
Main Results:
- No statistically significant differences were found in tooth size discrepancies between male and female Jordanian schoolchildren.
- 23.7% of subjects showed anterior Bolton ratios exceeding 2 standard deviations.
- 9.5% of subjects showed overall Bolton ratios exceeding 2 standard deviations.
Conclusions:
- Gender is not a significant factor in tooth size discrepancies within this Jordanian cohort.
- A notable percentage of Jordanian schoolchildren present with tooth size discrepancies, potentially requiring orthodontic attention.

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...

01:26Assessment of the Mouth
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

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.
