It is important to define the expression "oral health-related quality of life"; one of its many definitions mentions the impact that oral health has on the different activities that individuals carry out daily. The elderly are affected by various oral diseases, with tooth loss being the most common; moreover, they are a vulnerable age group in society. Therefore, the following objective was proposed: To determine the relationship between quality of life and oral health in users with removable partial dentures. The type of study conducted was observational, cross-sectional, and prospective; the sample consisted of 99 elderly individuals (PAMs), selected through probabilistic sampling. In the data collection, identification instruments were applied, including the CPOD index, IOHS, prosthesis condition index, and the Oral Health Impact Profile (OHIP-EDENT). The bivariate analysis was performed using the non-parametric Kendall’s Tau-b test for categorical and ordinal variables, with a p ≤ 0.05 and a 95% confidence interval. Our results show that 44.4% of the PAMs have regular oral health. The quality of life, as perceived by the PAMs, was good in 54.5%. Kendall’s Tau-b test yielded = -0.262 with a p = 0.004, showing a relationship between the two variables (quality of life and oral health status). Thus, it is concluded that quality of life is correlated with the oral health status of PAMs.

(Universidad Privada Norbert Wiener, 2019-03-21) Dionicio Salazar, Ana Teresa; Vergara Pinto, Brenda Roxana
The present research study is titled: "Evaluation of emotional exhaustion, depersonalization, and low personal accomplishment in Dentistry students at the Universidad Privada Norbert Wiener." This study was conducted to determine whether students at the Universidad Privada Norbert Wiener (UPNW) are affected by stress. According to the World Health Organization (WHO), an individual's mental health can be influenced by three basic factors: social, psychological, and biological, whose particular qualities determine a specific lifestyle for each person. The objective of this study was to assess emotional exhaustion, depersonalization, and low personal accomplishment in Dentistry students at UPNW. This was an observational, descriptive, cross-sectional, and prospective study carried out at UPNW. The study population consisted of students from the Professional Academic School of Dentistry who were in their eighth, ninth, and tenth cycles, totaling 164 students. The last cycles were chosen as they are considered to have a heavier academic load, as eighth and ninth cycle students are in the comprehensive clinical stage, and tenth cycle students face academic challenges outside their institution, competing with students from other universities in various hospitals. This type of competition can often lead to stress. Data collection utilized two instruments: a sociodemographic questionnaire and the Maslach Burnout Inventory questionnaire, which is globally used to assess this syndrome. For bio-statistical analysis, the Chi-square test was applied. The results showed that 20.1% of the population exhibited emotional exhaustion, depersonalization, and low personal accomplishment, while 79.9% showed none of these symptoms.

The aim of this study was to compare the color stability of two dental resins exposed to three commonly consumed staining beverages in the population of Lima. Two resins were used for aesthetic zone restorations (Omnichroma and Z350XT), and three staining beverages (coffee, Coca-Cola, and purple corn drink). The resins were formed into discs with a diameter of 10 mm and a thickness of 2 mm, using a mold where increments of 2 mm of resin were added until the required disc dimensions were achieved. Once the resin discs were made, the initial color was checked using the Vita classical color guide, and this information was recorded on the data collection sheet. In total, 30 discs of each resin type were made, with 10 discs for each beverage studied, for a total of 60 discs. The beverages were then prepared in separate jars, with 40 ml of each substance poured into a different jar. The resin discs were submerged in the beverages for 15 days, with the beverage being replaced after 7 days with the same substance. After 15 days, the discs were removed, rinsed, and dried, and the color was measured again, with the data recorded on the data sheet.

(Universidad Privada Norbert Wiener, 2022-02-16) Sangama Trujillo, Ricardo Eugenio; Vergara Pinto, Brenda Roxana
Objective: To determine the difference in marginal adaptation between metal crowns using the immersion technique and metal-free crowns using the CAD-CAM technique in the anterior sector. Methodology: Two types of materials commonly used for the production of dental crowns in the anterior sector were employed. These included 12 chrome-cobalt metal crowns made with the immersion technique and 12 metal-free crowns made with the CAD-CAM technique. These crowns were fabricated over a plaster model of a single dental piece (right central incisor) which had been previously prepared and molded. A total of 24 plaster models were required, with 12 for each study group. Once the crowns were made, they were cemented onto the models, and a cut was made exposing the vestibular and palatal sides. After obtaining both sides of the cemented crowns, the thickness of the cement in the cervical and medial portions between the vestibular face and the corresponding crown portion was measured, as well as the palatal face and its crown portion. Results: The results showed that only 79.2% of the metal crowns achieved marginal adaptation, while 100% of the metal-free crowns achieved adaptation. Furthermore, when comparing the marginal adaptation of the crowns, it was found that the marginal adaptation of the metal crowns was 75.35 and the marginal adaptation of the metal-free crowns was 10.54. Conclusion: Metal-free crowns made with the CAD-CAM technique achieved better marginal adaptation than metal crowns made with the immersion technique.

(Universidad Privada Norbert Wiener, 2019-06-18) Cotrina Cubas, Sonia Deysi; Vergara Pinto, Brenda Roxana
Dental malocclusion is an occlusal alteration, not considered a disease, and is conditioned by various ethnic and cultural traits, altering aesthetics and function. This makes it difficult to define and classify. The purpose of this research is to determine the frequency and severity of malocclusion and the need for treatment according to the Dental Aesthetic Index (DAI) in students aged 12 to 16 at Fe y Alegría School No. 53, Lima – 2018. Materials and Methods: This is a quantitative, descriptive, cross-sectional study with 113 students aged 12 to 16, evaluated through an intraoral clinical examination using the Dental Aesthetic Index (DAI). Data were collected, and a diagnostic team was used for the clinical examination. Results: It was determined that 51 (45.1%) students had "No abnormalities or mild malocclusion"; 27 (23.9%) students had "Manifest malocclusion"; 23 (20.4%) students had "Severe malocclusion"; and 12 (10.6%) students had "Very severe or disabling malocclusion." Additionally, when evaluating the prevalence of treatment needs for malocclusions from the mildest to the most severe, it was found that 51 (45.1%) students had "Unnecessary or slightly necessary"; 27 (23.9%) students had "Optional"; 23 (20.4%) students had "Highly desirable"; and 12 (10.6%) students had "Mandatory." Regarding the severity of malocclusions and the need for treatment based on age, statistically significant differences were found, while no significant differences were found by sex. Conclusions: It was concluded that the majority of individuals (45.1%) do not require orthodontic treatment.
