Summary
The golden proportion is not consistently found between maxillary and mandibular anterior teeth widths in the Indian population. This aesthetic principle may not accurately predict tooth width relationships in this demographic.
Area of Science:
- Dentistry
- Dental Aesthetics
- Anthropometry
Background:
- The golden proportion is a widely accepted aesthetic principle.
- Its application in determining ideal tooth proportions is debated.
- Understanding tooth width relationships is crucial for cosmetic dentistry.
Purpose of the Study:
- To evaluate the existence of the golden proportion between maxillary and mandibular anterior teeth widths.
- To assess the applicability of the golden proportion in the Indian population.
Main Methods:
- Clinical tooth width measurements were taken from 576 Indian patients (ages 21-30).
- Digital vernier calipers and a flexible ruler were used for precise measurements.
- Paired Student's t-test was employed for statistical analysis.
Main Results:
- The golden proportion was not observed between the widths of the right central and lateral incisors in 53% of women and 47% of men.
- The golden percentage showed inconstancy concerning relative tooth width.
Conclusions:
- The golden proportion is an inappropriate method for relating successive maxillary anterior tooth widths in the Indian population.
- This finding suggests limitations in applying universal aesthetic principles across diverse ethnic groups.

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.
