(Universidad Privada Norbert Wiener, 2025-11-17) Peralta Gonzáles, Erika Roxana; Gómez Carrión, Christian Esteban
El presente estudio tuvo como objetivo comparar entre dos métodos para la determinación cefalométrica en pacientes con valoración ortodóntica del Centro Odontológico Barzola E.I.R.L, 2024. Se realizó un Estudio cuantitativo, aplicado, de diseño transversal cuasiexperimental. Se analizaron 42 radiografías cefalométricas del Centro Odontológico Barzola E.I.R.L. Las mediciones se realizaron en tres modalidades: manual, digital y smartphone. Se empleó la prueba no paramétrica de Kruskal–Wallis para comparar grupos. Se evidenció que en las relaciones esqueléticas: SNA: digital 84.05 vs manual 83.06; SNB: digital 81.30 vs manual 80.46; smartphone mostró menor promedio en SNB (79.76); en las relaciones dentarias: IS.NA con diferencias mínimas (manual 26.90; digital 25.70; smartphone 25.57); en tejidos blandos: el smartphone no arrojó valores medibles (0.00) para S-labio superior/inferior, a diferencia de manual (4.40; 5.94) y digital (1.19; 2.82). En general, los métodos digital y smartphone obtuvieron resultados comparables al manual en la mayoría de variables (p>0.05); se observaron diferencias puntuales donde p<0.05. Se concluyó que, el análisis digital es globalmente comparable al manual para medidas esqueléticas y dentarias, con ligeras variaciones (tendencia a valores algo mayores en SNA y SNB), permitiendo concluir que no existe diferencias al comparar dos métodos para la determinación cefalométrica en pacientes con valoración ortodóntica.

In relation to the instrument that measures patient safety culture, it contains 42 questions and covers five dimensions, within which are teamwork, communication, safety culture, supervision, and management and direction. Similarly, the nursing care quality instrument comprises 21 items and covers three dimensions defined as technical, operational and human, taking into consideration that the two questionnaires are valid in terms of reliability and validity.

To determine the diagnostic validity of the Brazilian formula compared to the precipitation method for estimating low-density lipoprotein. Methodology: The research method is hypothetical-deductive, quantitative, descriptive, and non-experimental, based on 353 lipid profile results from patient records between January 2 and December 31, 2018. Results: Of the 353 results, 237 (67.1%) were from women, and 116 (32.9%) from men. The most common age group was adults aged 30-59 years, with 175 results (49.6%). There was a moderate level of agreement for the Brazilian formula. Conclusion: The Brazilian formula showed 93.8% sensitivity, 81.7% specificity, 93.5% positive predictive value, and 82.6% negative predictive value compared to the precipitation method.
