Teeth

Teeth

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...

Summary

High fluoride toothpaste effectively prevents bracket debonding on enamel subjected to acid erosion. This finding is crucial for maintaining orthodontic treatment integrity under erosive conditions.

Area of Science:

Dental Materials Science
Orthodontic Adhesion
Caries Prevention

Background:

Dental enamel erosion compromises bracket bond strength in orthodontic patients.
Fluoride dentifrices are commonly used for caries prevention, but their effect on bracket adhesion under erosive conditions requires investigation.

Purpose of the Study:

To evaluate the efficacy of high fluoride dentifrice in maintaining bracket bond strength on enamel after an erosive challenge.
To compare the effects of regular and high fluoride dentifrices against acid challenges of varying durations.

Main Methods:

Eighty-four enamel specimens were divided into seven groups, subjected to 3 or 6 cycles of acid challenge.
Groups were treated with either distilled water, regular fluoride dentifrice (1450 ppm F(-)), or high fluoride dentifrice (5000 ppm F(-)).
Bracket bond strength was assessed using a bond strength test after the erosive challenge.

Main Results:

No significant difference in bond strength was observed among groups after 3 cycles of acid challenge.
A statistically significant difference was found between regular and high fluoride dentifrices after 6 cycles of acid challenge (p < 0.05).
High fluoride dentifrice (5000 ppm F(-)) prevented the reduction in bracket bond strength observed in the regular fluoride group after 6 acid cycles.

Conclusions:

High fluoride toothpaste effectively preserves bracket bond strength on enamel exposed to erosive challenges.
The findings suggest that high fluoride dentifrices can be beneficial in orthodontic patients experiencing enamel erosion.
