Adhesive resistance against shear forces of metal brackets using different adhesive cements. In vitro study. Lima – Peru 2021
(Universidad Privada Norbert Wiener, 2022-01-25) Yanac Calero, Darwin Newton; Chanamé Marín, Ann Rosemary
One of the challenges in orthodontic treatment with braces is the installation and maintenance of fixed orthodontic appliances throughout the duration of the treatment. Therefore, the adhesive resistance to shear forces of metal brackets using different adhesive cements was determined. The research was experimental, cross-sectional, prospective, and comparative, where two types of cements were used: Orthocem and Heliosit, bonding to 20 dental pieces with their brackets. The laboratory mechanical procedure was then carried out using a universal testing machine, which applied vertical force at a rate of 1 mm/min until the brackets detached from the tooth, recording the data of this action. The adhesive resistance to shear forces of the metal brackets using the Orthocem adhesive cement was 2.592 ± 1.28 megapascals, and for the Heliosit adhesive cement, it was 2.437 ± 0.80 megapascals. The conclusion was that both Orthocem and Heliosit adhesive cements present similar adhesive resistance, with no statistically significant difference (p>0.05) to shear forces.

(Universidad Privada Norbert Wiener, 2022-11-12) Muñoz Rodríguez, Senith Aide; Menacho Angeles, Gregorio Lorenzo
Objective: To compare the adhesive resistance of fiberglass posts using two resin cement systems. Methodology: 7 teeth were used for each cement type (Relyx U200 and RelyX Ultimate). A transverse cut was made at 2 mm from the cement-enamel junction on each tooth. The root canal treatment was then performed. For cementing with Relyx Ultimate, 37% phosphoric acid and Scotchbond universal adhesive were used beforehand, while for Relyx U200 cementing, the cement was applied directly. After cementing the fiberglass post, all teeth were cut into 1 mm thick discs, resulting in 6 discs. These root portion discs were taken to the DHL mechanical testing laboratory, where they underwent push-out testing to measure adhesive strength using a universal testing machine. Results: The adhesive strength of the fiberglass posts with Relyx Ultimate resin cement was 37 ± 14.59 Mpa in the cervical portion, 32.61 ± 8.44 Mpa in the middle portion, and 34.29 ± 9.13 Mpa in the apical portion. For Relyx U200 cement, the values were 34.05 ± 9.23 Mpa in the cervical portion, 38.43 ± 14.29 Mpa in the middle portion, and 30.15 ± 15.17 Mpa in the apical portion. Conclusion: No significant difference was found in the adhesive strength of fiberglass posts using the resin cement systems Relyx U200 and RelyX Ultimate in all three root thirds.

(Universidad Privada Norbert Wiener, 2022-10-21) Sánchez Linares, Maricielo; Guevara Sotomayor, Juan César
The maintenance of oral health is influenced by pH levels, which can vary due to the consumption of acidic foods and beverages. The main issue to analyze is how artificial flavoring is associated with pH levels in locally marketed flavored water drinks. This aspect can be analyzed in a laboratory to measure the levels and their differences based on the flavor, with the ultimate goal of understanding the potential effects caused by the consumption of flavored beverages on the oral cavity and determining whether they provide any benefit to our health. Methodology: The sample used consisted of 5 types of beverages, with 25 samples divided into 5 of lemon flavor, 5 of blackberry and strawberry flavor, 5 of apple flavor, 5 of pineapple flavor, and 5 without flavor. Results: Based on the interpretation, it was determined that the p-value was greater than 0.05, allowing us to accept the null hypothesis and conclude that the variables are independent. Conclusions: The beverages used in the study showed varying pH levels among lemon, blackberry and strawberry, apple, pineapple, and non-flavored drinks, with acidic levels found in the flavored drinks, unlike the non-flavored drink. For dentistry, this generates a beneficial preventive result for the population.

Association of extrinsic dark dental pigmentation and dental caries in primary school students of educational institutions in the district of Cieneguilla 2023
(Universidad Privada Norbert Wiener, 2024-07-16) Godoy Augurto, Luis Miguel Antonio; Hidalgo Constantino, Judith
The study titled "Association of Dark Extrinsic Dental Pigmentation and Dental Caries in Primary School Students of Educational Institutions in the Cieneguilla District 2023" aimed to determine the relationship between dark extrinsic dental pigmentation and the degree of caries in primary school students of educational institutions in the Cieneguilla district in 2023, as well as to determine the prevalences of dark dental pigmentation, the Shourie index, and dental caries. The methodology used was hypothetical-deductive, observational, and analytical, with a quantitative approach, non-experimental design, and cross-sectional study. The results showed a significant relationship between dark pigmentation and the degree of caries in the students, with an association degree of 27%. The percentage proportion of caries gradually decreased in children with dark pigmentation. The prevalence of caries was found to be 85.7%, the group COP-D index was 4.14, the group caries index was 2.9, and the filling and extraction index was 0.05, respectively. It was concluded that there is a high prevalence of caries in the studied population, along with a 5.8% prevalence of extrinsic dark pigmentation, with a high prevalence of dark pigmentation of grade 3. The group COP index (4.1) is moderate, and the group caries index of 2.9 significantly lower than the COP index indicates that untreated caries prevalence is the main contributor to the COP index, and the low index (0.05) of fillings and extractions (0.05) can be interpreted as a lack of education in oral care and hygiene.
