evaluation of antibiotic sensitivity in samples from endodontic infections.

Objective: To develop an in vitro model for real-time monitoring of endodontic biofilm growth and evaluate the ex vivo effect of antibiotics on biofilm growth.

Material And Methods: Root canal samples were taken from 40 patients and inoculated into 96-well plates in a system that measures biofilm growth through electrical impedance. Biofilm bacterial composition at the genus and species level was analyzed by Illumina sequencing.

In vitro evaluation of microleakage in Class II composite restorations: High-viscosity bulk-fill vs conventional composites.

This study compared marginal microleakage of Class II cavities restored with bulk-fill resin (Filtek™ Bulk Fill) and conventional composite resin (Filtek™ Supreme XTE). Two standardized Class II cavities were prepared in forty extracted human molars. The gingival margin was located above the cemento-enamel junction for twenty molars (groups 1 and 2) and apically for the other twenty (groups 3 and 4) (n=20).

[Relationship between tobacco smoke and dental caries in school children at the Valencian Country].

Background: Recently, it has focused the role of exposure to environmental tobacco smoke in the etiology of dental caries, so we plan to evaluate the association between environmental tobacco smoke inhalation and caries experience in 10-15-years-old children.

Methods: A transversal descriptive study was designed. Carried out in the Primary Dentistry Unit.

Dietary habits of a school population and implications for oral health.

Aim: The study analyzes the consumption of cariogenic foods in a population of children between 6 and 10 years old.

Methods: Transversal descriptive study on a sample of 369 children who first attended to the Department 9 Dentistry dental office of the Valencia Region Health Agency (Spain). A self-administered food consumption frequency questionnaire was used to evaluate how often the food on the list were consumed by the children.

Evidence concerning the medical management of caries.

Caries is an infectious, chronic and cumulative disease. It seriously affects quality of life and creates considerable expense for individuals and communities. The disease can be managed by acting on biofilm formation and maturation, by modifying the kinetics of apatite solution or with a combination of the two processes.

The rôle of saliva in maintaining oral health and as an aid to diagnosis.

Saliva is a complex secretion. 93% by volume is secreted by the major salivary glands and the remaining 7% by the minor glands. 99% of saliva is water and the other 1% is composed of organic and inorganic molecules.

A clinical and radiographic comparison of caries diagnosed in approximal surfaces of posterior teeth in a low-risk population of 14-year-old children.

Introduction: The prevalence of caries, and its preferential location, has changed in recent years. The percentage reduction in caries has been lower in pits and fissures than in other locations, making it necessary to use more sensitive diagnostic procedures than visual inspection for approximal lesions.

Objectives: The objective of this study was to compare the amount of overlooked proximal caries by bitewing X-rays versus clinical in patients who were completing a public oral health program at the age of 14 years.

Methodological considerations in the determination of working length.

Aim: The aim of this study was to evaluate the diagnostic efficacy of an electronic system for the determination of working length, in comparison with two radiological methods (conventional film and digital radiography).

Methodology: The study sample consisted of 28 root canals belonging to 20 human mandibular teeth. A comparison was made between the working length measurements obtained by two radiological methods (conventional film and digital radiography) and an apex locator, using as gold standard the observation of the file position within the root following selective grinding of the root tissue.
