This study evaluated the concordance of Steiner, Ricketts, and the Element II of Andrews' Philosophy cephalometric analyses for determining the antero-posterior relationship of the upper maxilla in patients from the orthodontics second specialty clinic of the Universidad Norbert Wiener during the 2014-II to 2015-I period. It is an observational, prospective, cross-sectional study with a descriptive research level and a community or ecological design for multiple comparisons. Thirty cephalometric tracings were performed, which were evaluated by a single examiner. Each tracing underwent two cephalometric studies, and Element II of Andrews' philosophy was evaluated to determine the antero-posterior position of the upper maxilla. Results: The Steiner cephalometric analysis showed that 53% of patients had maxillary protrusion. The Ricketts cephalometric analysis showed that 57% of patients were within normal limits, and Element II of Andrews' philosophy showed that 60% of patients had maxillary retrusion. Using the Kappa statistical test, the study concluded that there was no concordance between the Steiner and Ricketts analyses (0.01946) for determining the antero-posterior position of the upper maxilla; nor was there concordance between the Element II of Andrews and Steiner cephalometric analysis (0.0865), or between Element II of Andrews and Ricketts cephalometric analysis (0.0948).

Evaluation of the photography of smiling profile in the orthodontic photography protocol
(Universidad Privada Norbert Wiener, 2017-12-13) Zavalaga Gutierrez, Agatha Betzabeth; Nieto Perea, Patricia
In orthodontics, photographs play a very important role as they aid in diagnosis. The standard photographic protocol typically includes intraoral and extraoral photographs; however, the profile smile photograph is often overlooked. Only a few prescriptions, such as that of Dr. ANDREWS, rely on the profile smile photograph to evaluate the position of the central incisor and obtain a better perspective of the clinical case. The objective of this study was to evaluate a clinical case using both a smile profile photograph and one without a smile. Four profile photographs without a smile were shown to experienced orthodontists, who provided their perspective on the case. After fifteen days, the same four photographs of the patients, but with a smile, were shown for comparison. The results indicated that using the profile smile photograph revealed more findings and details in the perception of the clinical case. It allowed for better analysis of the position of the upper central incisor, the relationship of the lips, and the harmony of the maxillae. Therefore, it is suggested to incorporate the profile smile photograph into the conventional orthodontic photographic protocol.

Evaluation of the reproducibility of the position of the upper central incisor with and without the Andrews six-element orthodontists' head frontal plane indicator device.
(Universidad Privada Norbert Wiener, 2018-02-05) Machado Stevenson, Olga Beatriz; Nieto Perea, Patricia
The present study evaluated the reproducibility of the upper central incisor (ICS) position, with and without the head's frontal plane indicator device, by orthodontists using the 6 elements of Andrews in 2016. The type and level of the research was prospective, longitudinal, and descriptive observational. The sample consisted of 29 orthodontists trained in the 6 elements philosophy, who took measurements at two times, with a 3-month interval between T1 and T2, with and without the frontal plane indicator device. At T1, using the device, a mean of -0.05mm (SD 2.69) was obtained, with statistically significant differences (p=0.04); and without the device, a mean of 2.62mm (SD 1.41) was found, with statistically significant differences (p=0.00). At T2, using the device, a mean of -1.55mm (SD 2.85) was obtained, with statistically significant differences (p=0.00); and without the device, a mean of 1.07mm (SD 1.65) was found, with no statistically significant differences (p=0.82). Both evaluated with a Gold Standard with a mean of 1mm (SD 1). The average over time with the device at T1 was statistically equal to the average at T2 (p=0.048). The study concluded that the greatest reproducibility is achieved using the Head's Frontal Plane Indicator Device.

NIVEL DE SATISFACCIÓN Y LA CALIDAD DE ATENCION PERCIBIDA POR EL USUARIO EXTERNO EN EL SERVICIO DE ORTODONCIA Y ORTOPEDIA MAXILAR DE LA CLINICA DOCENTE ASISTENCIAL DE LA UNIVERSIDAD NORBERT WIENER 2018
(Universidad Privada Norbert Wiener, 2019-05-30) Nieto Perea, Patricia; Yllú Ponce, Nancy Judith; Ayala Mendivil, Ronald Espíritu
En el presente estudio se evaluó la relación de la satisfacción y la calidad de atención percibida por los pacientes que acudieron al servicio de ortodoncia y ortopedia maxilar de la clínica docente asistencial de la universidad Norbert Wiener en el 2018.Fue una investigación aplicada, no experimental, transversal de tipo correlacional. La muestra estuvo conformada por 100 pacientes mayores de edad que solo hayan recibido atención en el servicio de ortodoncia y ortopedia maxilar. Los pacientes llenaron dos encuestas, donde la calidad de atención fue evaluada mediante una encuesta Servqual y la satisfacción fue evaluada mediante una escala de Likert. Los resultados demostraron una correlación sustancial de la satisfacción del usuario externo y la dimensión seguridad de la calidad de atención, al referir que el personal siempre fue amable y atento. Y, una correlación sustancial de la calidad de atención y la dimensión cognitiva de la satisfacción del usuario, al considerar que el personal estuvo capacitado y supo escuchar con paciencia. Se concluyó que existe relación estadísticamente significativa entre el nivel de satisfacción y la percepción de la calidad de atención percibida.
