En un estudio transversal de 174 pacientes operadas de cono frio se evaluó las características citopatológicas y quirúrgicas encontrando mayor prevalencia entre los 30 a 44 años (58.4%). La prevalencia de la lesión intraepitelial de alto grado (LIEAG) en el Papanicolaou fue de 75.4%. Los resultados de biopsia dirigida por colposcopia advierten que el 90.9% fue LIEAG. De la histopatología de cono, 73.6% fue LIEAG. El compromiso de bordes del cono cervical fue de 9.2% del exocervix y endocervix cada uno respectivamente y 3.5% de ambos márgenes. El Pap presentó una sensibilidad 84.7%,una especificidad de 19.2%, un valor predictivo positivo de 82.6% y un valor predictivo negativo de 21.7% respecto del cono. La biopsia tuvo una sensibilidad de 96.1%,una especificdad de 9.8%, un valor predictivo positivo de 76.7% y un valor predictivo negativo de 44.4% respecto del cono. La sensibilid...

Establece los factores de riesgo asociados a lumbalgia en pacientes del Hospital Nacional Daniel Alcides Carrión (Lima, Perú). El dolor musculoesquelético es un problema de salud pública a nivel mundial que afecta a las personas de todas las edades y representa una de las causas más comunes de discapacidad entre los adultos. De acuerdo con la Organización Mundial de la Salud (OMS), las condiciones más incapacitantes son las enfermedades musculoesqueléticas. Los factores relacionados con la lumbalgia son complejos y múltiples. Se han determinado numerosos factores de riesgo individuales y ambientales asociados al dolor lumbar, por ejemplo, los factores individuales, como el metabolismo, la bioquímica, los factores físicos y las tendencias depresivas. Además, se han identificado factores de riesgo ambientales, como la satisfacción laboral, levantar objetos pesados, estar de pi...

Introducción: El tipo de dieta influye directamente en el valor del pH salival, el cual es un factor importante para evitar la formación de caries. Objetivo: Evaluar el cambio del pH salival por ingesta ca riogénica y no cariogénica en preescolares de una institu ción educativa de Huaura, Perú. Métodos: Esta investigación fue de tipo observacional, comparativo y longitudinal. El tamaño de muestra fue de 30 preescolares. Después que los niños consumieron dieta cariogénica y no cariogénica, se evaluó su pH a diferentes tiempos. Para el contraste de resultados se utilizó la prue ba T Student y U de Mann-Whitney. Resultados: El pH salival con dieta no cariogénica a los cinco minutos fue 7,11 ± 0,19 y 7,09 ± 0,20, y, a los 40 mi nutos, 7,46 ± 0,19 y 7,42 ± 0,22, en mujeres y hombres, respectivamente.

The COVID-19 pandemic has generated much concern worldwide. Due to its high transmissibility, many young university students have had to carry out their academic activities in mandatory social isolation, which could generate excessive anxiety. Therefore, the aim of this study was to evaluate the anxiety levels in Peruvian dentistry students developed during COVID-19 mandatory social isolation. Materials and Methods: An analytical, observational, and transversal study was carried out in 403 dentistry students in the last two years from three Peruvian universities from May to July 2020. The Zung Self-Rating Anxiety Scale was used to detect anxiety symptoms and their respective diagnoses. A logit model was used to evaluate the association of the variables: age group (X1), gender (X2), type of university (X3), and marital status (X4), with the anxiety levels of the students, considering a p-...

Aim: The current study compared the push-out adhesive strength of glass fiber-reinforced posts with a silane-treated surface versus a universally adhesive-treated surface. In both cases, a universal self-adhesive cement was used. Materials and Methods: Thirty bovine teeth were used in an in vitro experiment. Through cutting, the root and coronal sections were divided. Subsequently, the manufacturer’s recommendations were followed for the placement of glass fiber-reinforced posts through root canal therapy, gutta-percha removal, and canal shaping. On the basis of how the posts were treated prior to cementation, the samples were split into three groups (n = 10). Posts in group A (control) did not get any prior treatment. Posts in group B had previously received a silane treatment. Posts in Group C had previously been coated with universal adhesive. Following the application of RelyX Ulti...

Objetivo: evaluar el efecto antibacteriano del peróxido de hidrógeno (H2 O2 ) al 6% comparado con hipo clorito de sodio (NaClO) al 1% y al 2%, sobre cepillos dentales inoculados con Streptococcus mutans atcc® 25175™. Materiales y métodos: estudio experimental in vitro, transversal y comparativo. Se utilizaron 60 cepillos dentales, divididos en 4 grupos de 15 cepillos cada uno. El número de muestra lo determinó la fór mula de comparación de medias, después de realizar un estudio piloto, y se seleccionaron por muestreo aleatorio simple. Se aplicaron las pruebas de normalidad de Shapiro-Wilk, y para la prueba de hipótesis, la U de Mann-Whitney. Resultados: el H2 O2 al 6% presentó una media de crecimiento de 2×109 ufc/mL, lo que indica que su efectividad es mayor comparada con el NaClO al 1%, que presentó una media de crecimiento de 4×109 ufc/mL, y esta es menor al NaClO al 2...

The ultrasonic cleaning method was found to be the most effective method for the removal of biologic waste when compared with the manual method with a nylon brush. However, there was no significant difference between these two methods when using enzymatic detergent. Both the manual method and the ultrasonic method showed significantly higher effectiveness when enzymatic detergent was used for the cleaning of Flexoreamer K-type files, although it is evident that neither method achieved complete removal of biologic waste from all Flexoreamer K-type files, which could lead to improper sterilization of endodontic files and, consequently, be a factor to be considered in clinical cross-infection.

The use of bleaching agents, despite being a conservative treatment, can cause a decrease in the surface microhardness of dental resins, affecting their aesthetics and performance. The aim of this study was to evaluate the in vitro effect of polishing on the surface microhardness of nanohybrid composite resins that were subjected to bleaching with 35% hydrogen peroxide. Materials and Methods: This cross-sectional, in vitro experimental study consisted of 30 composite resin samples made according to ISO 4049-2019 and divided equally into two groups (A and B) which were subjected to 35% hydrogen peroxide bleaching. Group A was subjected to polishing procedure, whereas group B was the control group. The samples were stored in distilled water at 37°C for 24 h. The Vickers microhardness was determined with a load of 100 g-f for 10 s. The data were analyzed with Student’s t-test for indepen...

“The use of chlorhexidine-based mouthwashes on resin composites with rough surfaces can cause discoloration which compromises the esthetic of patients. The present study aimed to evaluate the in vitro color stability of Forma (Ultradent Products, Inc., South Jordan), Tetric N-Ceram (Ivoclar Vivadent, Schaan, Liechtenstein) and Filtek Z350XT (3M, ESPE, St. Paul, MN, USA) resin composites, with and without polishing, after being immersed in a 0.12% chlorhexidine (CHX)-based mouthwash at different times. The present in vitro experimental and longitudinal study used 96 nanohybrid resin composite blocks (Forma, Tetric N-Ceram and Filtek Z350XT) 8 mm in diameter and 2 mm thick, evenly distributed. Each resin composite group was divided into two subgroups (n = 16) with and without polishing and then immersed in a 0.12% CHX-based mouthwash for 7, 14, 21 and 28 days. Color measurements were per...

The aim of this article is to evaluate the cleanliness level achieved with and without the application of enzymatic detergent for the manual method versus the ultrasonic method, applied to Flexoreamer K-type files No. 25, No. 30, and No. 35. Materials and Methods: 192 K-type Flexoreamer files were divided into four categories: A1 (ultrasonic method with enzymatic detergent), A2 (ultrasonic method without enzymatic detergent), B1 (manual method with enzymatic detergent), and B2 (manual method without enzymatic detergent). Each category was randomly distributed in three groups of 16 files each (No. 25, No. 30, and No. 35). The files were used for biomechanical instrumentation of the root canal in premolars. The active part of the files was examined under a stereomicroscope, considering four cleaning levels: 4 (100% cleanliness), 3 (95– 99% cleanliness), 2 (85–94% cleanliness), 1 (75–...
