(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.

pH variation and saliva flow in pregnant women under 18 years old from the National Hospital Guillermo Almenara Irigoyen located in La Victoria district, Lima 2018
(Universidad Privada Norbert Wiener, 2019-11-14) Rodriguez Mannuci, Biancca Lucia; Girano Castaños, Jorge Alberto
The main objective of this research was to determine the levels of pH and salivary flow in pregnant adolescents under 18 years old from the Guillermo Almenara Irigoyen National Hospital in the La Victoria district, Lima-2018. This research is descriptive, prospective, cross-sectional, analytical, and relational in nature. Salivary flow was collected and salivary pH was determined in 30 pregnant adolescents and 30 non-pregnant adolescents from the control group. Results: The pH values for the pregnant adolescents averaged 6.49, indicating an acidic pH, and the salivary flow was 3.1ml, resulting in low secretion or low salivary flow. Conclusion: No significant variation was found in the levels of pH and salivary flow between pregnant and non-pregnant adolescents under 18 years old.

Relationship between the state of conservation of total protesis and amount of salival flow of elderly patients in the Canevaro asylum Lima-2018
(Universidad Privada Norbert Wiener, 2019-11-22) Saucedo Ventura, Iris Vanesa; Del Castillo Ayquipa, Armando
This research is correlational and prospective in nature. The design is observational, as the phenomena were observed without manipulating the study variable. Additionally, it is cross-sectional, as the data were collected at a single point in time. The target population for this research consisted of 100 elderly residents at the Canevaro Nursing Home. The data collection technique employed was the survey, and the instrument used was a questionnaire, which consisted of a set of items aimed at gathering relevant information to meet the research objectives. The results showed that salivary flow was as follows: 39.0% of patients had a flow rate of 0.3 to 0.5 ml/min, 32.0% had an increased flow rate of >0.5 ml/min, and 29.0% had a decreased flow rate of <0.3 ml/min. Regarding the condition of the removable dental prosthesis, 79.0% of the patients had their total removable prosthesis regularly maintained, 11.0% had a well-maintained prosthesis, and 10.0% had a poorly maintained prosthesis. Additionally, applying the Spearman's Rho correlation yielded a coefficient of 0.055 with a significance level of 0.586 (p > 0.05). The study concluded that the amount of salivary flow is not related to the condition of the total removable dental prosthesis.

Relationship of pH and salival flow with the use of fixed orthodontic appliances in patients attended in the Dental Care Private Clinic - Lima, 2018
(Universidad Privada Norbert Wiener, 2019-12-11) Pinedo Rufino, Yolita; Garavito Chang, Enna Lucila
The purpose of this research was to determine the relationship between pH and salivary flow with the use of fixed orthodontic appliances in patients treated at the private clinic Dental Care, Lima 2018. The sample consisted of 50 participants aged 14 to 25 years, with 25 using orthodontic appliances and 25 not using appliances. An sterile container was provided to each patient to collect saliva accumulated over a five-minute period. A previously calibrated potentiometer was used to measure pH, and a graduated syringe was used to measure salivary flow. The bivariate analysis of pH and salivary flow with the study groups was conducted using chi-square and Mann-Whitney U tests, respectively. Prior to the test selection, data normality was verified using the Shapiro-Wilk test. A significance level of 5% was used. Results: Statistically significant differences were found, with a decrease in salivary pH and an increase in salivary flow in patients with orthodontic appliances compared to those without orthodontics. It is concluded that the use of orthodontic appliances alters the normal values of pH and salivary flow.
