The combined conservative treatment of superficial teeth discoloration
Now there is a tendency in favour of favorabile opinion on the importance of use of
fluorides as helping in reducing indexes of caries both in the developed, and in underdeveloped
countries.
The widespread use of methods of fluorination promoted decreasing of prevalence of
caries.
Nevertheless, at the same time indexes of a tooth fluorosis, apparently, grow in a reciprocal
proportion. It is caused by a chronic poisoning with the fluorine, caused by consumption of
fluoric bonds for a long time or their high concentration in potable water, nutrition etc.
Owing to the given treatment or residing in the endemic foci of a fluorosis, we can observe
augmentation of maculae with a various colour on tooth surface which affect dental aesthetics.
Currently, the search of adequate aesthetic restorative treatment is increasing, but, despite
the wide assortment of restorative materials on the market, there is no material which would
correspond on properties and characteristics to dental hard tissues.
Enamel microabrasion is an effective method to remove surface discoloration, caused by
this condition which damages an aesthetics of that tissue. The use of 18 %-s' hydrochloric acids
in a combination with pumice in spite of the fact that was a simple and cheap method, was
gradually replaced because of its potential of bringing of harm to periodontal tissues.
In search of revealing of conservative treatment approaching for improvement of a tooth
aesthetics, this research has been spent for the purpose of an estimation of efficiency of technics
of a enamel microabrasion using acid liquid of zinc phosphate cement in a combination to
abrasive dentifrice powder in thematic clinical cases, encountered by the employees of chair of
Preventive Dentistry of USMF "N. Testemiţanu" in University’s stomatologic clinic. As criterion
for an estimation of cases were taken the photos, registered at the beginning and after application
of a series of the combined therapy based on a microabrasion and a remineralization of an
enamel (alternating topical application of fluorides with calcium preparations are taken; in case
of a fluorosis local application of fluorides is contraindicated !!!).
Thereby, this article reports the clinical case of treatment of the dental fluorosis solved by
means of a enamel microabrasion, using acid liquid of zinc phosphate cement because its costbenefit
ratio is better than in a case with a hydrochloric acid. |
