La caries de infancia temprana (CIT) es uno de los problemas bucales más frecuentes en los niños a nivel mundial, en donde diversos factores estarían asociados a su desarrollo. Así tenemos que, el estado nutricional alterado en un individuo desde edades tempranas afectaría la condición de la cavidad bucal. Asimismo, el desequilibrio de los microorganismos orales juega un rol importante en este problema bucal. Sin embargo, existen bacterias propias de la cavidad bucal que resultan ser beneficiosas y actuarían contra la caries dental, como el Streptococcus dentisani. El objetivo de este estudio fue determinar el estado nutricional y factores microbiológicos orales asociados con la CIT en niños preescolares que residen en el distrito de Villa El Salvador. Los estudios fueron realizados en niños que provenían de un estudio de cohorte de nacimiento previa, de los que se contaba con...

Objetivos: Evaluar el impacto de los problemas bucales en la calidad de vida en niños de 3 a 5 años de la Institución Educativa Inicial del distrito Hualmay de la provincia de Huaura, departamento de Lima en el 2011. Material y Métodos: Este estudio fue de tipo descriptiva, transversal. Evaluó a 153 niños, a quienes se les examinó la cavidad bucal y al responsable del cuidado del niño se aplicó el Early Childhood Oral Health Impact Scale (ECOHIS); previamente se realizó la validación peruana. Un examinador calibrado evaluó tres problemas bucales: caries de infancia temprana, traumatismos dento-alveolares y maloclusiones en dientes anteriores. Se realizó el análisis estadístico; aplicando pruebas de Anova, U Mann Whitney y Kruskal Wallis  con un nivel de significancia de 95%. Resultados: La frecuencia de caries de infancia temprana fue de 76,47%; de traumatismos dento-alve...

Congenital cytomegalovirus is a double-stranded DNA virus belonging to the Herpesviridae family that causes intrauterine infection. Infants can be either asymptomatic or symptomatic at birth. Severe outcome was defined as: neonatal death and/or severe neurodevelopmental symptoms and/or severe cognitive impairment. This study aims at showing the antimicrobial effect of the modified 3-mix paste in the treatment of acute apical periodontitis in a female child patient with congenital cytomegalovirus, in a single session. The 2-year and 3-month-old female patient has symptomatic congenital cytomegalovirus infection and ongoing long-term side effects. At the stemmatological level, the patient presented with multiple carious lesions, reversible pulpitis and acute apical periodontitis. Also, pulpectomies were performed on teeth 61, 62, 51, 52, 81, 71, 54 and 64 in a single session, under general...

Introducción: La alfabetización en salud bucal (ASB) alude a las habilidades cognitivas y sociales que permiten a las personas obtener, procesar y comprender informaciones sobre el cuidado de la salud bucal que les permitan tomar decisiones correctas al respecto. Objetivo: Recolectar información actualizada referida a la asociación entre la ASB de los padres y la salud bucal de sus hijos. Materiales y métodos: Se realizó un proceso de búsqueda de publicaciones científicas en las bases de datos PubMed, Scopus, LILACS, SciELO y Google Scholar. Se utilizaron los descriptores “Oral Health Literacy”, “Health Literacy”, “Literacy in Dentistry”, “Oral Health”, “Oral Condition”, “Dental Caries”, “Early Childhood Caries”, “Children”, “Child, Preschool”, “Infant”, “Parents” y “Parenting”. Fueron incluidos artículos científicos publicados en...

Objectives: determine the total length and the largest diameter in cervical, middle and apical level of deciduous mandibular first molars using cone beam computed tomography. Materials and method: In this cross-sectional study a sample of 21 deciduous upper first molars with the length of the complete root and no fracture was analyzed. The teeth were scanned using CT Cone Beam, the diameter of the root canal was measured by taking three points of reference for these measures, cervical, middle and apical. The obtained images were examined and measured by mean a 3D processing imagery software. The measures of the ducts was made by a single observer (CCI= 0.70); nonparametric Kruskal-Wallis test to compare and find the differences were used. Results: The average length of deciduous upper first molars was 13.53 mm, 5.61 mm crown and root 7.92 mm. The average diameter of the palatal root cana...

Objetivo: Determinar la longitud total y diámetro mayor a nivel cervical, medio y apical de los conduc-tos radiculares de la raíz palatina (Rp), raíz mesial (Rm) y raíz distal (Rd) del primer molar superior de-ciduo utilizando la tomografía Cone Beam. Materiales y método: Estudio descriptivo transversal. Una muestra de 21 primeros molares superiores deciduos con la longitud de la raíz completa y sin fractura. Los dientes fueron escaneados utilizando la Tomografía Cone Beam y se midió el diámetro del conducto radicular tomando tres puntos de referencia: cervical, medio y apical. Las imágenes obtenidas fueron analizadas y medidas mediante un software procesador de imágenes 3D. Las medidas de los conductos fueron realizadas por un solo observador (CCI=0.70). Se usaron las pruebas no paramétricas de Kruskal-Wallis para comparar y encontrar las diferencias. Resultados: Longitud m...

BACKGROUND: TO EVALUATE THE PERFORMANCE OF DIFFERENT PREDICTION MODELS BASED ON MACHINE LEARNING TO PREDICT THE PRESENCE OF EARLY CHILDHOOD CARIES. MATERIAL AND METHODS: CROSS-SECTIONAL ANALYTICAL STUDY. THE SOCIODEMOGRAPHIC AND CLINICAL DATA USED CAME FROM A SAMPLE OF 186 CHILDREN AGED 3 TO 6 YEARS AND THEIR RESPECTIVE PARENTS OR GUARDIANS TREATED AT A HOSPITAL IN ICA, PERU. THE DATABASE WITH SIGNIFICANT VARIABLES WAS LOADED INTO THE ORANGE DATA MINING SOFTWARE TO BE PROCESSED WITH DIFFERENT PREDICTION MODELS BASED ON MACHINE LEARNING. TO EVALUATE THE PERFORMANCE OF THE PREDICTION MODELS, THE FOLLOWING INDICATORS WERE USED: PRECISION, RECALL, F1-SCORE AND ACCURACY. THE DISCRIMINATORY POWER OF THE MODEL WAS DETERMINED BY THE VALUE OF THE ROC CURVE. RESULTS: 76.88% OF THE CHILDREN EVALUATED HAD CAVITIES. THE SUPPORT VECTOR MACHINE (SVM) AND NEURAL NETWORK (NN) MODELS OBTAINED THE BEST PER...

Objectives: Estimate the root canals of primary first lower molars by means of Nano computed tomography (Nano-CT). Material and methods: The sample consisted of 10 inferior primary molar teeth. The teeth were scanned by Nano-CT and the resulting images were analyzed with the On-Demand 3D software, considering among the evaluation the anatomical characteristics of the root canals and surface area of the root canals throughout the root length. For the measurement of the larger and smaller diameter of the root canals the statistical tests were central trend measures, with a significance level of 5%.  Results: In the distal root, vestibular mesial and lingual mesial , the size of the root canal with the highest average of the cervical region (D0) was 1.30, 1.00, 1.08 mm, respectively. The diameter to the deepest length (D11) for the same canals was 0.29, 0.22, 0.18 mm. The measurement o...
