Introduction: Early childhood caries (ECC) is a health problem of worldwide interest. The purpose of this literature review is showed how an inadequate feeding practices by breastfeeding and bottle feeding contribute to early childhood caries. Materials and methods: A systematic online review of the existing literature from 2012 to 2018 was performed in the Medline database, using key words such as Caries, Breastfeeding, Bottle feeding and Childhood. Results: 61 articles were obtained, of which, 25 were considered in this review because they are considered to be related to the objective of this review. The literature reviewed showed a direct relationship between the presence of CIT and the way of feeding, with no difference between the types considered. Conclusions: Prolonged breastfeeding more than two years of age of the infant as well as the use of bottles added with sugars and carboh...

Aim: To determine the prevalence of three canals in the mesial root of the first permanent mandibular molars, of patients who come for root canal treatment at the dental clinic of the Equinoctial Technological University, Quito, Ecuador from January 2013 to December 2017. Materiales and Methods : A descriptive observational study is presented, in a sample of 55 clinical histories of patients with root canal treatment at the dental clinic of the Health Sciences faculty "Eugenio Espejo" of the Equinoctial Technological University, between January 2013 to December 2017. After a review of the medical records of patients treated during this period of time and inclusion criteria, the selected radiographs were examined in a negatoscope with the help of a magnifying glass, by a single person trained in reading images and with experience in endodontic treatments. The findings were reported in spe...

Objective: Evaluate the microfiltration degree of three temporary cements: IRM®, OBTUR ® and CAVIT® subjected to artificial aging. Methods: In 60 third molars, without caries, extracted because of therapeutic indication, cavities were made in the occlusal surface with pulp chamber opening of 4 mm x 4 mm, after irrigation with 2.5% NaClO and drying with cotton, the molars were randomly divided into three groups (n: 20) placing in each of them one of the three cements. The teeth were subjected to thermocycling at temperatures of -5, 37 and 55 ° C; during 900 continuous cycles, after which they were immersed in methylene blue for 24 hours, then sectioned and analyzed under a stereomicroscope to determine the microfiltration degree. Two fragments of each group were chosen randomly and prepared for scanning electron microscopy (SEM) observation. Results: The highest microfiltation degree ...

Objetivo: Evaluar el grado de microfiltración de tres cementos provisionales: IRM®, OBTUR® y CAVIT® sometidos a envejecimiento artificial. Métodos: En 60 terceros molares, libres de caries, extraídos previa indicación terapéutica, fueron realizadas cavidades en la superficie oclusal con una apertura a cámara pulpar de 4 mm x 4 mm, tras irrigación con NaClO al 2,5% y secado con algodón, los molares fueron divididos aleatoriamente en tres grupos (n: 20) colocando en cada uno de ellos uno de los tres cementos. Los dientes fueron sometidos a termociclado con temperaturas de -5, 37 y 55 °C; durante 900 ciclos continuos, tras lo cual fueron inmersas en azul de metileno por 24 horas, seccionados y analizados bajo estereomicroscopio para determinar el grado de microfiltración. Dos fragmentos de cada grupo fueron escogidos al azar y preparados para observación al microscopio electrÃ...
