Summary
This study measured maxillary anterior tooth dimensions in Saudi adults, finding a squarish tooth form with minor left-right asymmetry. These dimensions show similarities to the Turkish population, aiding aesthetic dental restorations.
Area of Science:
- Dentistry
- Anthropology
- Aesthetics
Background:
- Restoring anterior teeth requires natural smile aesthetics.
- Accurate tooth dimensions are crucial for successful dental restorations.
- Understanding population-specific tooth morphology aids in achieving predictable aesthetic outcomes.
Purpose of the Study:
- To measure and analyze the dimensions of maxillary anterior teeth.
- To determine the relative width proportions of these teeth in a Saudi subpopulation.
- To provide data for aesthetic dental restorations in this demographic.
Main Methods:
- 180 Saudi adults (20-30 years) with intact maxillary anterior teeth participated.
- Maxillary dental casts were created, and digital calipers measured tooth length and width.
- Digital photography of casts calculated relative width ratios.
Main Results:
- Mean widths: Central incisor 8.74mm, Lateral incisor 6.64mm, Canine 7.82mm.
- Mean lengths: Central incisor 9.84mm, Lateral incisor 8.09mm, Canine 9.08mm.
- Lateral incisor/central incisor width ratio: 63.69%; Canine/lateral incisor ratio: 78.35%. No significant gender or side differences.
Conclusions:
- Saudi anterior teeth exhibit a squarish form.
- Minor asymmetry was observed between left and right sides.
- Dimensions show similarities to the Turkish population, informing aesthetic dental practice.

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...

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.
