Chemical and accessibility characteristics of children’s toothpaste marketed in Lima-Peru, 2022
(Universidad Privada Norbert Wiener, 2023-11-06) Acevedo Alvarez, Fiorella Del Rosario; Arauzo Sinchez, Carlos Javier
The purpose of this research was to evaluate the chemical characteristics and accessibility of children's toothpaste sold in Lima, Peru. The methodology used in the study was descriptive, cross-sectional, and comparative, where both physical and virtual searches were conducted for children's toothpaste sold in Lima Metropolitan area. A total of 8 stores were considered (Vivanda, Tottus, Plaza Vea, Wong, Metro, Inkafarma, Mifarma, and Hogar&Salud), recording their chemical characteristics (total fluoride) and accessibility (sale price). A total of 72 children's toothpastes were found in the 8 stores, of which, excluding duplicates, 23 different toothpastes were recorded. These were categorized by the presence of total fluoride: 3 without fluoride; 5 with low concentration; 13 with the recommended concentration for children, and 2 with high concentration. Thirteen percent did not contain fluoride, and 21.7% had a low concentration of fluoride. Fifty-six point five percent had a concentration of 1000 ppm, while 8.7% had a high fluoride concentration (>1100 ppm). The toothpastes showed a variety of flavors, with bubblegum flavor being the most prominent. The prices of the recommended children's toothpastes ranged between 3.2 soles and 18.9 soles, with an average price of 9.7 soles.

Effect of 1.23% acidulated fluorphosphate and 2% sodium fluoride on the fracture resistance of resin-modified glass ionomer
(Universidad Privada Norbert Wiener, 2024-06-14) Canales Rios, Alexandra Yveth; Menacho Angeles, Gregorio Lorenzo
The methodological design was observational, comparative, and cross-sectional. A total of 45 samples of glass ionomer discs with a resin composition from a commercial brand (Vitremer) were used, with a diameter of 2 mm and a thickness of 6 mm, distributed into groups: for the first group, 15 discs of ionomer with a resin composition were treated with 0.05 ml of 1.23% fluoride from a commercial brand (Maquira); for the second group, 15 discs of ionomer with a resin composition were treated with 0.05 ml of 2% fluoride from a commercial brand (Maquira), and both groups were treated with fluoride for 4 minutes, followed by washing and drying. The third group consisted of 15 discs of ionomer with resin composition to which no fluoride was applied. The results of the Tukey HSD multiple comparison test showed a statistically significant difference (p=0.000) between the resistance of the acidulated phosphate fluoride group at 1.23% (mean=21.36360 Kg/mm²) and the control group (mean=25.36360 Kg/mm²). In conclusion, the average resistance of the fluoride group at 1.23% concentration and the fluoride group at 2% concentration did not show statistically significant differences (p=0.198).

pH values of fluorinated mouthwashes marketed in Peru in 2021
(Universidad Privada Norbert Wiener, 2021-08-03) Zorrilla Reyes, Sheyla Sugey; Chanamé Marín, Ann Rosemary
Objective: The objective of this study was to determine the average pH value of fluoridated mouthwashes sold in Peru in 2021. Methodology: This was an observational-comparative study. Seven commercial brands were evaluated, with a sample of 21 fluoridated mouthwashes, three per group: Colgate Plax Ice Glacial Zero Alcohol, Colgate Plax Soft Mint Zero Alcohol, Listerine Cuidado Total Zero, Listerine Anticaries, Oral B Complete, Dento Menta Zero Alcohol, and Vitis Orthodontic. A digital pH meter, previously calibrated, was used to measure the pH, and the data were processed using ANOVA and Tukey tests. Statistically significant differences were found in the average pH values (p=0.000, p<0.05), and these were considered acidic since the values ranged from 3.93 to 6.27. Of the evaluated brands, 6 (86%) had values below the critical pH of 5.5, which is considered potentially erosive for enamel. Listerine Anticaries was the most acidic with a pH of 3.93, and Dento Menta Zero Alcohol was the least acidic with a pH of 6.27, being the only brand above the critical value. Conclusion: It is suggested that the pH value be expressed on the commercial label to take it into account when choosing the most appropriate mouthwash based on the patient's needs, considering the benefit/side effect balance.
