The sample size of 13 volunteers was calculated for a 5% significance level, 80% power, 7.4% of enamel microhardness loss as estimated standard deviation, and 7.7% as minimum detectable difference in means of enamel microhardness loss based on the demineralization
data of a previous study.
Therefore, studies about the prevention of caries and reversing the decay or the demineralization
process concentrate on the effect of fluoride ions.
Intrinsic source to induce this erosion is mainly associated with gas1tric acid in oral cavity followed by vomiting, regurgitation or gastro esophageal reflux.A1 Although, teeth are exposed to continuous cycles of demineralization
followed by remineralization, this delicate balance can easily be disturbed due to extensive use of low pH drinks like soft drinks, fruit juices, acidic beverages, wines and candies leading to acidic dissolution of the inorganic phase of tooth and subsequent loss of tooth substance.2
demonstrated that glass ionomer cements that release fluorides diminish tooth enamel demineralization
in fixed orthodontic treatment (8).
A combination of chemical and biological methods can also be used: Manni, Ghorbel-Bellaaj, Jellouli, Younes and Nasri (2010) achieved demineralization
by acid treatment (HCl 1,5 M, 6 hours) and the deproteination by using extracellular proteases isolated from B.
The samples were subjected to pH cycling 6 times a day for 8 days (demineralization
and remineralization) in conjunction with the treatments according to the groups.
's materials used were weak acid, acetic acid (C[H.sub.3]COOH 1 M) and strong acid, hydrochloric acid (HCl 1 M).
Soda pop has emerged as one of the most significant dietary sources of acid capable of producing demineralization
of the enamel.
In the second part of questionnaire, questions were asked regarding the preventive measures used by orthodontists when demineralization
is noticed developing during orthodontic treatment.
When oral hygiene is less than favorable, demineralization
areas called "white spots" are frequently seen around orthodontic brackets; these spots are characterized by their opacity compared to healthy enamel .
Oil shale is also examined for the effect of different acids and alkali on its demineralization
, pyrolysis kinetics and oil-yielding rate, etc.
