Study Regarding the Influence of Different Fluoride Compounds on Dental Hard Tissues Resistance to Acid Challenge

Abstract:

The aim of the study is to assess the effect of different fluorine compounds on dental hard tissues resistance against acid attacks by enamel hardness evaluation. Seventy five enamel slabs were split in five groups (I-IV) according to the five toothpaste included in this study. All the groups were divided in three subgroups (a-c). The samples of subgroup a were immersed in artificial saliva during the study (control), the samples of subgroup b were submitted to acid attack for 8 min, twice a day, 7 days and the samples of subgroup c were immersed in a toothpaste suspension for 3 min, 1 h before the exposure to acid attacks. The mean enamel Vickers hardness number(VHN) was recorded for each sample using the digital device CV 400 DAT (Namicon). The protective effect of each toothpaste (PR%) was evaluated as following PR% = (VHNc-VHNb)/(VHNq-VHNb) x 100. This study demonstrated a high protection against erosive attacks provided by all types of toothpastes tested. The higher protective effect was recorded by the toothpaste Blend-a-med Pro-Expert, followed by Splat Professional Active, Lacalut Alpin and Sensodyne Repair. The toothpaste having no fluoride in composition demonstrated the lowest protective effect. The association of fluoride with other active ingredients increased the protective effect of toothpastes. Keywords: remineralisation, hard dental tissues, erosive attacks, fluorine
