Effects of tannin-fluoride and milk-fluoride mixture on human enamel erosion from inappropriately chlorinated pool water

In Vitro Evaluation of Remineralization Potential of Five Toothpastes on Soft Drink-Eroded Human Enamel and Dentine

OBJECTIVE

The purpose of this in vitro study was to evaluate the potential remineralization of enamel and dentine erosion lesions after the application of five different toothpastes.

METHODOLOGY

A total of 104 enamel and dentine samples were prepared from maxillary third molars. Each group was divided according to the toothpaste application mode (topical = 56; brushing = 48) and the toothpaste used seven topical groups and six brushing groups (n = 8). The groups included negative control (NC), positive control (PC), Sensodyne Pronamel (SP), Regenerate (R), Regenerate with boosting serum (R+), Colgate Duraphat 5000 (CD), and tooth mousse (TM).

RESULTS

The statistical analysis showed significant surface microhardness (SMH) change. All enamel groups showed a significant decrease in SMH compared to NC for both application modes. However, no significance was recorded between test groups. Similar results were observed between dentine groups and their relevant controls for both application modes, except brushed R and R+ groups, which were insignificant to their NC. For topical groups, TM showed a significant increase in SMH. While R and R+ showed lower loss than SP and CD.

CONCLUSIONS

All tested agents offered a degree of remineralization in both enamel and dentine with no significant difference between agents in enamel groups while R, R+, and TM offered better results in dentine groups.

CLINICAL SIGNIFICANCE

 For dentine groups, similar findings were observed with superior tooth surface protection with the application of TM over other agents. Tooth surface remineralization was achieved when agents were either applied topically or brushed over the surface.

Regular Physical Activity and Dental Erosion: A Systematic Review

Dental erosion is the irreversible pathological loss of hard tissues, which are chemically dissolved by acids, especially through external means, such as diet (e.g., fruit juices, isotonic or energy drinks). This systematic review was designed to answer the question “Is there a relationship between dental erosion and regular physical activity with or without sports drink consumption?” Following the inclusion and exclusion criteria, sixteen studies were included in this systematic review (according to PRISMA statement guidelines). Based on the meta-analysis, physically active individuals who declared regular consumption of sports drinks had a more than 2.5-fold increase in the odds of erosive lesions. In general, nearly half of the people who practiced sports experienced tooth erosion, and more than half frequently consumed sports beverages. Despite the heterogeneity of the included studies (different age groups, various sports disciplines), regular physical activity was associated with an increased risk of dental erosion, especially under the influence of frequent consumption of sports drinks.
