Antecedentes: el Cuestionario de Percepción del niño (CPQ), el Cuestionario de Percepción de los Padres (P-CPQ) y la Escala de Impacto Familiar (FIS) son instrumentos que evalúan la calidad de vida relacionada a salud bucal (CVRSB) en niños desde su percepción y sobre aquellas provenientes de sus padres o tutores. La falta de estos instrumentos en el idioma Español, limita su uso para investigaciones en salud oral en los países hispano hablantes. El objetivo de este estudio fue validar la versión en español de tres instrumentos para evaluar la CVRSB a través de sus propiedades psicométricas (validez y confiabilidad). Métodos: Las versiones peruanas del CPQ, P-CPQ and FIS se obtuvieron a través de la traducción y retro-traducción de los instrumentos y su adaptación transcultural, la cual fue evaluada en dos pruebas pilotos en 60 individuos; posteriormente, la versión fin...

Objetivo: Comparar el potencial de remineralización a través de la microdureza del esmalte de premolares con desmineralización artificial, expuestos a dos barnices fluorados: NaF al 5% (Duraphat) y NaF al 5% con TCP (Clinpro™ White Varnish). Metodología: El estudio in vitro incluyó 45 bloques de esmalte que fueron divididos al azar en tres grupos:Grupo 1 (grupo control), Grupo 2 (NaF al 5%) y Grupo 3 (NaF al 5% con TCP). Se crearon lesiones artificiales de caries en el esmalte y luego se aplicó a cada grupo el barniz correspondiente. La muestra fue sometida a pH cíclico por cinco días consecutivos y luego la microdureza superficial fue medida usando la prueba de dureza Vickers. Resultados: La microdureza superficial obtenida después del régimen de tratamiento en cada grupo fue mayor que los valores de microdureza superficial post desmineralización artificial, en dond...

Objective: Determine which of the toothpastes; a toothpaste with 1.5% arginine and 1450 ppm fluoride, one with 10% xylitol and 1450 ppm fluoride and a toothpaste with 1450 ppm fluoride; It is most effective in reducing the saliva count of S. mutans in 5-year-old children. Materials and methods: The sample consisted of forty-five 5-year-old children divided into 3 groups corres­ponding to each paste to be evaluated, a toothpaste with 1.5% arginine and 1450 ppm of fluoride, one with 10% xylitol and 1450 ppm of fluoride and one with 1450 ppm of fluoride. Counts of CFU of S. mutans were carried out in sowings made on MSB agar, of stimulated saliva samples obtained from the subjects of the sam­ple, before and after two weeks of the use of the paste assigned to each subgroup. Results: The mean S. mutans count before was 727.59 CFU and after it was 103.50. The significance was 0.000 between t...

 Introduction: The pain management during a dental appointment is a challenge that pediatric dentists constantly face, especially during procedures that require the usage of local dental anesthesia. The use of topical anesthesia on oral mucosa can reduce the perception of pain, improving the relationship between the child and the professional. Objective: The objective of the study, was to realize a literature review, about the topical anesthetics most used in pediatric dentistry. Methodology: An information search was count from June 2019 to January 2020 about topical anesthetics used in pediatric dentistry using the platforms: EBSCO, Scielo, Pubmed, Cochrane and Google Scholar, using the key words: dental topical anesthetic, pediatric dentistry, benzocaine. topical, topical lidocaine, EMLA, PLO4%. Results: The initial bibliographic search gave 1733 studies, the information obtained...

Objective: To determine the esthetic perception of the smile according to gingival exposure in undergraduate university students of dentistry and other degrees of different ages and sex in Lima, Peru 2020, and descriptively evaluate the main variables such as age and sex. Methodology: A woman's smile was photographed following esthetic parameters, digitally modifying gingival exposure and obtaining six digital images. The images were rated by 512 students of dentistry and other degrees by means of a virtual survey using the Visual Analog Scale (values 0 to 10). Results: The students perceived the 0.5 mm gingival exposure smile as more attractive and the 2.5 mm gingival exposure smile as unattractive. According to age, students aged 18 to 23 years perceived the 0.5 mm gingival exposure smile as more attractive and the 2.5 mm gingival exposure smile as less attractive, while students aged ...
