The degree of pigmentation of teeth with composite resin and acrylic resin was determined in in vitro tests influenced by carbonated beverages. The total sample consisted of 32 teeth, divided into two groups of 16 elements, made of composite resins and acrylic resins. The study was longitudinal and experimental, comparing the degree of pigmentation due to exposure to carbonated beverages at 30 and 60 minutes. Statistical analysis was performed using Pearson's statistical test. The variations showed an initial average color value of composite resin and Coca-Cola of 92.3375, for Fanta® 92.4000; acrylic resin with Fanta® 79.9875, Coca-Cola® 81.6000. After 30 minutes of exposure, composite resin with Coca-Cola® had a value of 87.8125, Fanta® 91.5125; acrylic resin with Fanta® 85.5750, acrylic resin with Coca-Cola® 91.0125. After 60 minutes, composite resin with Coca-Cola® had a mean value of 80.4750, with Fanta® 81.8500, acrylic resin with Fanta® 81.4875, acrylic resin with Coca-Cola® 82.6000. Conclusion: Carbonated beverages influence the degree of pigmentation of teeth with composite and acrylic resins.

Effect of glycerinon color stability in a nano-filled resin exposed to drinks carbonated, Lima 2022

The objective of this study was to determine the color stability of a nanofilled resin with and without glycerin exposure to carbonated beverages. Methodology: Three carbonated beverages (Coca Cola®, Inka Cola®, and Red Bull®) were used as liquid pigments against the nanofilled resin (Filtek Z350 XT), which was previously molded into discs measuring 10 x 2 mm. These discs were divided into two groups: one group had glycerin gel applied to its surface before the final photopolymerization, while the other group did not. The initial color of the discs was identified using the Vita classical color guide through visual method. Once the colors were identified, the discs were placed in separate groups and each group was submerged in a container with a different carbonated beverage. The resin discs remained in the containers for a period of 14 days, being removed only at 7 and 14 days to verify the color. This information was tabulated and processed using ANOVA statistical analysis. Results: The Z350 XT resin, with and without glycerin, exposed to Coca Cola®, Inka Cola®, and Red Bull® for 14 days showed no significant color variation (p > 0.05). Conclusion: The color stability of nanofilled resin with and without glycerin exposed to carbonated beverages was similar.

PH and salivary flow in the health personnel of a hospital emergency service after the consumption of carbonated and milk drinks. Callao 2020.
(Universidad Privada Norbert Wiener, 2020-12-07) Castañeda Machado, Esther; Vilchez Bellido, Dina
The objective of the study was to determine the pH and salivary flow in healthcare personnel from an emergency hospital service after the consumption of carbonated and dairy beverages in Callao, 2020. The sample consisted of 43 healthcare professionals from the emergency hospital service, whose basal pH and post-ingestion pH at 5, 15, and 30 minutes were recorded, as well as salivary flow before and after beverage consumption. The research type was quasi-experimental, prospective, longitudinal, and descriptive. Data were recorded on a form and later analyzed statistically using SPSS software 21.0, including paired T-test, one-way ANOVA, and repeated measures ANOVA with a significance level of p<0.001. Results showed that the average pH in healthcare personnel before consuming carbonated and dairy drinks was 6.83 ±0.38. The average basal volume and volume/minute were 3.88±1.48 and 0.77±0.29 respectively, showing a tendency to be symmetric, with values detailed according to the type of drink. Comparing the change in volume and vol/min between drink type and basal value, all cases showed an increase, which was significant (p<0.001). Additionally, final volume and vol/min values among the four drinks did not show a significant difference (p=0.47 and p=0.29, respectively). pH values at 5, 15, and 30 minutes also showed differences between groups (p<0.001), with a tendency towards an increase in pH value. It is concluded that salivary pH decreased and salivary flow volume increased in healthcare personnel from an emergency hospital service after consuming carbonated and dairy beverages; however, only dairy beverages returned to their initial pH, while carbonated drinks, particularly Coca Cola, did not recover their pH within the determined time.
