ABSTRACT

RESUMEN Objetivo: El objetivo fue definir los contenidos mínimos y sus indicadores de aplicación clínica en el currículo de cariología para las escuelas de odontología chilenas. Metodología: Basados en los 5 dominios curriculares internacionales, se elaboró un documento que define los contenidos e indicadores de aplicación clínica para la enseñanza de cariología en Chile. Posteriormente, profesores de cariología de 20 de 21 escuelas de odontología chilenas (95%), sesionaron para revisar, retroalimentar y elaborar el documento final, denominado "Listado de contenidos mínimos e indicadores de aplicación clínica" en cariología para estudiantes de pregrado de odontología en Chile. Resultados: Se definieron 23 contenidos y 31 indicadores de aplicación clínica para la enseñanza de la cariología. La cantidad de contenidos e indicadores separados por dominio fueron respectivamente: conocimiento de base: 5 y 7; riesgo/detección y diagnóstico: 6 y 6; toma de decisiones/manejo preventivo no operatorio: 5 y 5; decisión de tratamiento operatorio: 4 y 9 y cariología basada en la evidencia: 3 y 4. Conclusiones: Se definieron los contenidos mínimos que tributan a cada dominio y sus indicadores de aplicación clínica para la enseñanza de la cariología en Chile.


ABSTRACT: The objective: was to define the minimum contents and their indicators of clinical application in the cariology curriculum for the Chilean Dental Schools. Methodology: Based on the 5 international curricular domains, a document defining the contents and indicators of clinical application for the teaching of cariology in Chile was elaborated. Later, cariology professors from 20 out of the 21 Chilean Dentistry Schools (95%) met to review, feedback and elaborate the final document, called "List of minimum contents and indicators of clinical application" in cariology for undergraduate dentistry students in Chile. Results: Twenty-three contents and 31 indicators of clinical application for the teaching of cariology were agreed upon. The amount of contents and indicators separated by domain respectively were: basic knowledge: 5 and 7; risk/detection and diagnosis: 6 and 6; decision making/non-operative preventive management: 5 and 5; decision of operative treatment: 4 and 9 and evidence-based cariology: 3 and 4. Conclusions: The minimum contents for each domain and its clinical application indicators for the teaching of cariology in Chile were defined.

ABSTRACT

Background: Streptococcus mutans (S. mutans) is associated with the onset of caries. Since root exposure in patients affected by periodontitis leads to higher caries rates, progressively more severe forms of periodontal disease might associate with elevated counts of S. mutans. Aim: To determine whether increasingly destructive forms of periodontal disease are associated with higher counts of S. mutans in untreated patients. Methods: 206 subjects aged 20-75 were classified into three groups according to the severity of periodontal disease: 1) gingivitis, 2) chronic slight periodontitis and 3) chronic moderate or chronic severe periodontitis. S. mutans counts (cfu/mL) were obtained by direct counting on selective agar plates from saliva samples. A cumulative proportional logistic regression model was adjusted for S. mutans counts. Results: The model failed to show differences by gender, but periodontal diagnosis had a significant effect on S. mutans counts depending on age. While in the group with moderate and severe periodontitis the probability of having high counts of S. mutans significantly increased with age, the probability remained unchanged in individuals with chronic slight periodontitis or gingivitis. Conclusion: High S. mutans levels appear directly co-associated with increased severity of periodontal disease at older ages in untreated patients.

ABSTRACT

Una alteración del flujo salival es clave en el desarrollo de caries, enfermedad periodontal e infecciones oportunistas. El flujo salival está determinado por diversos estímulos que actúan sobre receptores de distinta naturaleza, entre ellos mecanoreceptores articulares. Algunos estudios demuestran que las cargas articulares actúan sobre estos receptores, modificando cualitativa y cuantitativamente la secreción salival. El objetivo de este estudio fue determinar si existe una relación entre la aplicación controlada de cargas articulares y cambios en el flujo y pH salival. 30 voluntarios fueron seleccionados según criterios de inclusión establecidos. Se elaboró un dispositivo interoclusal que en relación a piezas 1.5 y 2.5, tenía botones acrílicos de 1 mm de espesor, los que al ejercer fuerzas sobre ellos provocan cargas reversibles sobre la ATM. Antes de usar el dispositivo, en cada individuo se midió flujo salival no estimulado (FSNE) el flujo salival estimulado (FSE) y el pH de ambos. Tras un periodo de adaptación diaria por una semana, cada participante usó el dispositivo durante 1 hora, ejerciendo fuerza masticatoria sostenida. Luego se midieron ambos flujos y el pH correspondiente. El procedimiento fue repetido por 7 días, bajo supervisión. No se observó una relación aparente entre la aplicación controlada de cargas articulares y cambios volumétricos de flujo salival. Las mujeres tuvieron un FSE y FSNE menor al de los hombres. La aplicación de sobrecargas articulares por un breve período de tiempo provoca una caída del pH del FSE luego de 3 días de aplicación.


Altered salivary flow is key for the onset of dental caries, periodontal disease and opportunistic infections. Salivary flow is determined by various stimuli on several receptors, including joint mechanoreceptors. Some studies show that loads on the TMJ affect these receptors causing changes on the quality and quantity of saliva secretion. The aim of this study was to determine whether a relation exists between controlled load application and changes on salivary flow and pH. Thirty volunteer subjects were recruited after excluding by inclusion criteria. A total coverage intraoral appliance was made with 1 mm acrylic buttons on tooth 1.5 and 2.5. The buttons were intentioned to direct the force vectors to apply a reversible load on the TMJ. Before using it, the Unstimulated salivary flow (USF), the Stimulated salivary flow (SSF) and the pH from each flow was obtained from each subject. After an adaptation period of a day, each volunteer used the appliance exerting steady moderate loads 1 hour/day for one week. Under the supervision of the examiner, the USF, SSF and both pH were daily registered for the entire week. There was not an apparent association between applying controlled loads on the TMJ and volumetric changes of the salivary flow. Women, however, showed lower USF and SSF than men. Load application through an oral appliance is associated with SSF pH drop from the third day.
