Early childhood caries (ECC) is a worldwide public health problem. The biological and behavioural determinants that are directly involved in ECC have been well documented; however, evidence on the effects of some psychosocial factors remains conflicting. This study aimed to assess the association between child temperament and ECC in Chilean preschoolers. Prior approval of the protocol was obtained from the ethics committee of Universidad de La Frontera (Folio N° 020_17), and all of those involved in the study provided signed informed consent forms. The cross-sectional study was conducted with 172 children aged 3 to 5 years attending preschools in Temuco, Chile. Each child’s temperament was assessed based on parents’ responses to the Early Childhood Behaviour Questionnaire. The outcomes assessed were caries prevalence and caries experience (dmft scores). The covariates included were socioeconomic position, cariogenic diet, prolonged breastfeeding, presence of dental plaque and hypoplasia. Logistic regression models were used to predict caries prevalence and negative binomial regression for caries experience. The prevalence of ECC was 29.1%, and the most frequent child temperament was ‘effortful control’. Regression model analyses, adjusting for covariates, showed no evidence of an association between any domain of children’s temperament (surgency, negative affect and effortful control) with the prevalence of caries or caries experience. This cross-sectional study found no association between childhood temperament and ECC in preschool children for this population. However, due to the specificity of this population, the association cannot be entirely ruled out. Further studies are needed to help understand the association between temperament and oral health, including the influences of family environment factors and culture.

Interprofessional education has become widely recognised as fundamental to educate new generations of dentists able to successfully join the dental public and private sectors and provide appropriate dental treatment to complex patients in a complex health system. This article presents the innovated curriculum of the dentistry course at Universidad de La Frontera describing its interprofessional education components. The description of IPE in the dental curriculum was done using Institutional documents. The university vocational training policy provides the framework in which IPE is implemented in undergraduate courses. Six out of eight dental curriculum components included IPE in their educational methodologies: 'Integrated units', 'Culture, society and mankind', 'Prevention', 'Professional Projections', 'Integrated clinics', and 'Professional Practice'. IPE is present thorough the dental course from first to final year and it takes different forms within each component. IPE is one of the methodologies used to achieve the learning outcomes stated in the curriculum. Passing through all modules of the dental curriculum leads to the development of generic and professional skills that allow students to obtain their professional title.

Clínico (LMC) demostrando el grado de eficiencia, mediante Bioluminiscencia. La técnica que permite una medición cuantitativa rápida de los residuos orgánicos de superficie, por la cuantificación de cantidad de Adenosín Trifosfato (ATP). Empleándose un Luminómetro, 3M™ Clean-Trace™, se programó la medición de contaminación en dos puntos claves, región interdigital e hiponiquio, en ambas manos, por medio de la lectura de Unidades Relativas de Luz (URL). Se analizó la contaminación previa a la técnica de LMC y posterior al desarrollo de la técnica, en las regiones indicadas, por medio de Hisopado v/s aprobación/rechazo considerando como Aprobado <250 URL y Rechazado >251 URL., nivel de contaminación v/s sexo, y distribución de aprobación/rechazo tanto antes y después de realizada la técnica de LMC. El muestreo previo al LMC determinó en todas las localizaciones muestreadas existen rangos de aprobación/ rechazo entre 35-42,5 % / 57,5-65 %, encontrándose la mayor contaminación en ambas manos en hiponiquio. Posteriormente de realizada la técnica de LMC el rango de corte de aprobación/rechazo fue de 80-90 % / 10-20 %, el porcentaje más alto se pesquisó en mano izquierda hiponiquio. Para el análisis estadístico se utilizó el programa estadístico SPSS Statistics for Windows, análisis descriptivo, prueba t-test, prueba de Levene. Un valor de p < 0,05 para significancia. Obteniéndose diferencias significativas en análisis del valor la media, según zonas de muestreo y rangos de aprobación/rechazo en URL, que varían entre p=0,000 y p=0,015, que se presentó en mano izquierda zona interdigital posterior al LMC. Según la media concluimos que las regiones hisopadas tanto previas y posteriores a la ejecución del LMC en hiponiquio la piel está más contaminada, que es paradojal ya que la técnica incorpora un acento en esta localización, tiene un mejor acceso y contacto con jabón y agua. PALABRAS CLAVE: bioluminiscencia, adenosín trifosfato, lavado de manos clínico, odontología.
