Abstract
|
|
|
The purpose of this study was to evaluate facial form, arch from and tooth from in young adults to determine if a correlation exists.
115 subjects who had healthy natural maxillary incisors and good occlusion consisted of 71 males and 44 females ranging from 20-30 years of age. Facial photographs and, intraoral photographs of upper anterior teeth and dental casts of upper jaws
were
taken to demonstrate facial from, dental arch from and tooth from.
From analysis is determined by comparing the ratio of the widths of the faces, dental archs and the teeth. The Chi-square test of independence between facial from, arch from and tooth from, was executed and the significance level determined.
@ES The results were as follows:
@EN 1. The distribution of facial forms was 66.1% square-tapering, 27.0% square, 5.2% ovoid, 2% tapering-square.
2. The distribution of tooth forms was 65.2% ovoid, 20.0% square-tapering, 11.3% tapering-square, 3.5% square.
3. The distribution of arch forms was 50.4% square-tapering, 48.7% tapering, 0.9% reverse tapering-square.
4. There was no large differences in the distribution of facial forms, dental arch forms and tooth-forms between male and female.
5. No relationship existed between the tooth form and the facial from.
6. No relationship existed between the facial from and the dental arch form.
7. No relationship existed between the tooth from and the dental arch form.
8. This gave the impression that dental arch from and facial form could not be used as a true index in tooth selection.
