Objective: The purpose of this study was to determine access to dental health services among Peruvian children aged 0 to 11 years, based on the National Demographic and Family Health Survey for the periods 2017–2019. Methodology: This was a longitudinal, observational, descriptive, and retrospective study. Data collection was performed by extracting information from the database of the National Demographic and Family Health Survey for the years 2017 to 2019. The dataset was downloaded, and the question regarding access to oral health services was selected. Results: The study analyzed a population of 132,883 children, of whom 3,092 did not respond to question 803: "Has (NAME) ever been treated by a dentist or in a dental service?" The final sample consisted of 129,791 Peruvian children aged 0 to 11 years. Regarding the area of residence, 66.9% (n=86,823) were from urban areas and 33.1% (n=42,968) from rural areas. Geographically, 46.7% (n=60,653) were from the Coastal region, 32% (n=41,530) from the Highland region, and 21.3% (n=27,608) from the Jungle region. Conclusion: The majority of children aged 0 to 11 years did not have access to dental health services, according to the National Demographic and Family Health Survey for the periods 2017–2019.

(Universidad Privada Norbert Wiener, 2021-12-09) Marroquin Acero, Evelin Rubali; Hamamoto Ichikawa, Jessica María
The objective of this study was to determine the fluoride concentration in bottled water sold in Lima, Peru, using a deductive and hypothetical method, with a quantitative approach and an observational, prospective, and cross-sectional design. Methodology: The sample consisted of three batches of bottled water from the following brands: San Mateo, San Luis, and Cielo, where the fluoride concentration was measured with a potentiometric instrument using the Ion Plus Sure-Flow Fluoride Electrode 9609BNWP, Thermo-Orion, coupled with the Multiparametric VERSA STAR VSTAR-40A2, Thermo-Orion for reading. The results showed that the average fluoride concentration in San Luis bottled water was 0.0126 ppm, in San Mateo it was 0.1840 ppm, and in Cielo bottled water, it was 0.1268 ppm. The study concluded that the analyzed bottled waters did not contain adequate levels of fluoride, and significant differences were found between San Luis and Cielo (p=0.016), San Luis and San Mateo (p=0.000), and Cielo and San Mateo (p=0.016). San Mateo had the highest fluoride concentration, while San Luis had the lowest. Furthermore, the bottled water brands studied did not meet the optimal fluoride levels of 0.7 ppm F recommended by the American Association of Drugless Practitioners (AADP).

(Universidad Privada Norbert Wiener, 2019-03-20) Mejía García, Jesus Miguel; Hamamoto Ichikawa, Jessica María
This research aimed to determine the relationship between Helicobacter Pylori in dental plaque in children aged 7 to 11 years in anterior and posterior teeth at the Institución Educativa 3095 Perú Kawachi, Lima 2018. The sample consisted of 50 students aged 7 to 11 years, from whom a dental plaque sample was taken during an intraoral examination of both anterior and posterior teeth from the vestibular and lingual surfaces. The sample was placed in a test tube containing urea reagent (transport medium) and then sent to the laboratory for a urea culture test. The study was descriptive, observational, retrospective, and cross-sectional. Data analysis was conducted using the SPSS v22.0 statistical package, with the Chi-square statistical test used to assess the association between variables. To determine prevalence, a frequency table was used. The results showed that 72% of children aged 7 to 11 had Helicobacter Pylori in their dental plaque. The study concluded that all students had Helicobacter Pylori present in both anterior and posterior teeth. It was also concluded that there was no statistically significant difference in the presence of Helicobacter Pylori based on gender or age according to the P-value. The majority of students presented Helicobacter Pylori, with factors of risk identified.

Relationship of the level of knowledge and attitude towards harmful oral habits on dental occlusion, in mothers who attend the Calderón Dental Clinic in the district of Comas, Lima 2021.
(Universidad Privada Norbert Wiener, 2022-05-09) Egúsquiza Rojas, Jorge Carlos; Hamamoto Ichikawa, Jessica María
To determine the relationship between the level of knowledge and attitude towards harmful oral habits affecting dental occlusion in mothers attending the Calderón Dental Clinic, Comas, Lima, 2021. Methodology: A quantitative, observational, cross-sectional, and correlational study. The sample consisted of 90 mothers who completed questionnaires on knowledge and attitudes toward harmful oral habits. Spearman's coefficient was used for correlation. Results: 60% of mothers had a regular knowledge level, and 66.7% had an indifferent attitude. A significant relationship was found between regular knowledge (38.9%) and an indifferent attitude (p≤0.05). Regular knowledge in specific dimensions (e.g., harmful oral habits, types of malocclusion, and preventive measures) was also linked to indifferent attitudes. Conclusion: A regular knowledge level was associated with an indifferent attitude toward harmful oral habits affecting dental occlusion, with a moderate, positive correlation (Rh=0.615).
