Purpose: The study aimed to determine the DMFT (Decayed, Missing, and Filled Teeth) index, salivary flow volume, and salivary pH level in pregnant and non-pregnant adolescents at the Second Level Hospital Barranca - Cajatambo. Data Collection and Analysis: Data were recorded on a form and statistically analyzed using SPSS software version 21.0. Statistical tests used included Chi-square (X2) and Spearman's correlation coefficient, with a significance level of 0.05. Conclusions: It was found that 63.10% of the pregnant adolescent group belonged to the late adolescence stage, with these results being statistically significant (p=0.000). The DMFT index for pregnant adolescents was high at 50.80%, with these results being statistically significant (p=0.00). It was observed that the salivary flow volume (ml/min) was high in the group of non-pregnant adolescents, with these results being statistically significant (p=0.00). Pregnant adolescents showed an acidic salivary pH level of 66.5%, with these results being statistically significant (p=0.00). Additionally, it was found that pregnant adolescents aged 17 to 19 years had a high DMFT index (5.95 ± SD 5.47), with these results being statistically significant (p=0.008 and 0.002). Finally, the relationship between DMFT and salivary flow volume and DMFT and salivary pH level showed statistically non-significant results (p>0.05).

Consumption of blueberries in the variation of salivary pH in primary school students of the Los Ingenieros Educational Institution, Lima 2022
(Universidad Privada Norbert Wiener, 2023-12-06) Chira Elias, Fidel Kane; Evaristo Quipas, Pamela
It has been scientifically proven that a compound found in blueberries called proanthocyanidin, a high molecular weight polyphenol, has properties that inhibit and prevent the bacterial biofilms responsible for dental plaque, thereby inhibiting the development of pathogenic bacteria that cause periodontal tissue degradation. It also prevents bacteria such as Streptococcus mutans, the causative agent of cavities, from forming acids that weaken dental tissues and facilitate the accommodation of harmful bacteria inside damaged teeth. The study aims to determine the relationship between blueberry consumption and changes in salivary pH in primary school students at the Los Ingenieros Educational Institution, Lima 2022. The study methodology is based on a hypothetical-deductive method, with a quantitative approach and a quasi-experimental design. The study population will consist of 200 students from the Los Ingenieros Educational Institution. The study method will be recorded using data collection forms for processing and obtaining results and hypothesis testing.

General Objective: To determine the effect of chewing gum with xylitol on salivary pH levels in children aged 6 to 12 years at the María Auxiliadora Private Institution. Methodology: This was a prospective, observational, and descriptive study with a longitudinal design. The sample consisted of 100 students, to whom a validated instrument based on expert judgment, consisting of a technical sheet, was applied. Results: After chewing gum with xylitol, the salivary pH change was greater within the first 10 minutes with xylitol (6.9) compared to without xylitol (5.7), and in comparison to the control group (5.4). After 20 minutes, the pH change was higher with xylitol (7.1) than without xylitol (6.0), and in comparison to the control group (5.4). After 30 minutes, the pH change was higher with xylitol (7.3) than without xylitol (6.3), and in comparison to the control group (5.4). The significance value was 0.00, which is less than 0.05, thus rejecting the null hypothesis and accepting the alternative hypothesis, which states that chewing gum with xylitol increases salivary pH. Conclusion: A significant change in salivary pH values was observed after chewing gum with xylitol, proportional to the time elapsed.

Effects of toothpaste with xylitol on the salival profile in 4 year old children of the I.E. Public Nº 20403 Carlos Martínez Uribe. Huaral – Lima 2023
(Universidad Privada Norbert Wiener, 2024-07-16) Rojas Félix, Nicolle Iveth; Guevara Sotomayor, Juan César
The objective of this research was to determine the effect of toothpaste with xylitol on 4-year-old children at the public I.E. No. 20403 Carlos Martínez Uribe, Huaral – Lima 2023. Methodology: The research method used was experimental with a quantitative approach, descriptive type, and longitudinal design. The researcher used a checklist created for a sample of 30 children, divided into two groups. Results: The following observations were made: In the experimental group, which was provided with toothpaste without xylitol on day 1, day 7, and day 21, the salivary pH remained within the range of (6.44±0.05), with a variation of +0.14. However, in the experimental group that received toothpaste with xylitol, the pH remained in the range of 6.38 to 6.90, with a range of (6.90±0.05), showing a variation of +0.52. This indicates that the use of only three doses of toothpaste with xylitol over a short period of time was able to increase the salivary pH compared to conventional toothpaste. Conclusion: The salivary pH of children who used toothpaste without xylitol experienced a variation of +0.52. This variation was positive and significant.

(Universidad Privada Norbert Wiener, 2023-12-06) Chihua Enciso, Deysi Magdalena; Salcedo Rioja, Mercedes Rita
The objective of this study was to compare the in vitro effect of generic paracetamol and ibuprofen on salivary pH. The research used a hypothetical deductive method with a quantitative approach, applied type, and a completely randomized experimental design with one factor (type of solution). The number of replicates for each solution was determined with a 95% confidence level and 90% power. Thirty saliva samples were collected for each solution, with samples randomly assigned to each solution. Each sample contained 1.1 ml of saliva, with 30 samples assigned randomly to a 120mg/5ml paracetamol solution and 30 to a 100mg/5ml ibuprofen solution. 1.1 ml of each solution was added to each sample, and pH was recorded at 0, 15, and 30 minutes. Statistical analysis was performed using summary indicators of position and dispersion, and after applying normality tests to the variables, inferences were made using Student’s t-tests for comparing the means of two independent samples. The average salivary pH was 7.58, the paracetamol solution had a pH of 4.97, and ibuprofen had a pH of 4.05. The average pH recorded at time zero, when each solution was added to the samples, was 5.76 for paracetamol and 4.39 for ibuprofen. After 15 minutes, the average pH for paracetamol was 5.91 and for ibuprofen, it was 4.45. After 30 minutes, the average pH of the samples containing paracetamol was 5.93, and for those containing ibuprofen, it was 4.50. Conclusions: A critical pH level was achieved at all three time points with ibuprofen, affecting the saliva's ability to neutralize acids

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.

Objective: The objective of this research was to determine the erosive potential of the most common liquids in a school lunchbox among children aged 3 to 6 years from I.E.P. “Mi Lucero,” Chorrillos district, through variations in salivary pH. Materials and Methods: This was an experimental, comparative, and longitudinal study. A total of 103 children aged 3 to 6 years with deciduous dentition, with and without dental caries, and with adequate OHI, were evaluated. Prior to the examination, teeth were brushed using the modified Stillman technique, and after one hour, baseline salivary pH was measured with a digital pH meter. Following the ingestion of liquids (Coca Cola, orange Frugos, and lemonade), salivary pH was measured at 5, 40, and 60 minutes. The data were analyzed using Student’s t-test with a significance level of p<0.05, revealing the greatest salivary pH drop at 5 minutes post-ingestion, particularly after drinking Coca Cola (pH 6.3). Recovery and stabilization were observed more rapidly with lemonade (pH 7) and orange Frugos (pH 7) at 40 minutes compared to the initial pH.
