“…All these effects on the enamel could be explained by the presence of substances such as ascorbic acid 48 and malic acid, 49 which can bind calcium to the enamel, causing porosities in the enamel crystals, and therefore, erosion, which could cause a rougher surface, thus facilitating bacterial adhesion. 28,30,47 We also found the presence of sucrose, glucose and fructose50. Streptococcus mutans produces glucans from sucrose to increase bacterial accumulation, 15 which would explain the increased bacterial adherence to the tooth surface.…”

Introduction: The lack of knowledge about denture hygiene can negatively affect their maintenance. On the other hand, good oral hygiene can reduce the chances of plaque accumulation. Objetive: To determine if there is a relationship between knowledge of hygiene and denture maintenance. Material and Methods: A questionnaire was applied to 67 patients who wore partial and/or total removable prostheses daily to evaluate their knowledge of denture hygiene. For the evaluation of denture maintenance, clinical inspection of the removable prosthesis was carried out using the Vigild criterion to observe the amount of plaque that was adhered to it. Data were statistically processed with Spearman's correlation test to determine the relationship between hygiene knowledge and denture maintenance. Results: The patients presented a medium (37.3%) and low (56.7%) denture hygiene knowledge; and fair (68.7%) and poor (11.9%) maintenance of their prosthesis. There is a statistically significant relationship between hygiene knowledge and denture maintenance (p<0.001). Conclusion: There is little knowledge of denture hygiene. This level of knowledge has a statistically significant relationship with the maintenance of the prostheses.

“…It is controversial in the literature whether bleaching gel has an effect on enamel microhardness. Previous studies reported a decrease in enamel microhardness after using 10% CP solutions [ 57 ] and 10% CP hydrogel [ 14 ]. In contrast, other studies reported no change of enamel microhardness of using 10% CP hydrogel [ 58 , 59 ].…”

Development of Controlled-Release Carbamide Peroxide Loaded Nanoemulgel for Tooth Bleaching: In Vitro and Ex Vivo Studies

Burst release of carbamide peroxide (CP) from traditional hydrogels causes severe inflammation to periodontal tissues. The present study explores the development of a novel CP nanoemulgel (CP-NG), an oil-in-water nanoemulsion-based gel in which CP was loaded with a view to controlling CP release. CP solid dispersions were prepared, using white soft paraffin or polyvinylpyrrolidone-white soft paraffin mixture as a carrier, prior to formulating nanoemulsions. It was found that carrier type and the ratio of CP to carrier affected drug crystallinity. Nanoemulsions formulated from the optimized CP solid dispersions were used to prepare CP-NG. It was found that the ratio of drug to carrier in CP solid dispersions affected the particle size and zeta potential of the nanoemulsions as well as drug release behavior and tooth bleaching efficacy of CP-NG. Drug release from CP-NG followed a first-order kinetic reaction and the release mechanism was an anomalous transport. Drug release rate decreased with an increase in solid dispersion carriers. CP-NG obtained from the solid dispersion with a 1:1 ratio of CP to the polymer mixture is suitable for sustaining drug release with high tooth bleaching efficacy and without reduction of enamel microhardness. The developed CP-NG is a promising potential tooth bleaching formulation.
