Core Cariology Curriculum Framework in Spanish for Latin American dental schools: development and consensus.

The aim of this study was to develop and achieve consensus on a cariology teaching framework for dental schools in Latin American Spanish-speaking countries. The Delphi process, with a ≥8 0% pre-defined participants' agreement, included three phases and a Coordinating Group. During the Preparation phase three panels of experts were selected and invited to participate: a) Regional academic/professional Dental Associations (Associations-Panel): n = 12; b) Regional Dental Schools (Dental-Schools-Panel): existing dental schools (n = 263) from the 19 Spanish-speaking regional countries; c) International academic/professional associations Peer Experts (Peer-Panel): n = 4. Based on consensus documents from Europe, Colombia, the Caribbean, USA, Chile and Spain, and updated scientific evidence, the Coordinating Group developed a baseline framework proposal of domains, main competencies (MC) and specific competencies (SC). The Consultation-Agreement and Consensus phases included three rounds of questionnaires with a step-wise sharing of the MC updated version of the consensus framework with the Dental-Schools-Panel and including SC with the Associations-Panel. Diverse communication strategies were used ( e.g ., independent google-form questionnaires and workshops). Consensus was reached after an on-site Associations-Panel workshop and secret voting, followed by an online meeting with the Peers-Panel. A total of 127 academic/professional institutions participated (Associations-Panel: 11, 91.6%; Dental-Schools-Panel: 112, 42.6%, all countries; Peers-Panel: 4, 100%). The baseline Cariology teaching framework of 5 domains, 10 MC and 92 SC underwent modifications after agreements for a final consensus framework consisting of 5 domains, 10 MC and 85 SC. A Core Cariology curriculum framework in Spanish for Latin American Dental Schools was successfully developed and agreed upon with regional dental academic and professional institutions.

Penetración de tres adhesivos en lesionesinterproximales de caries de mancha blanca: estudio in vitro / Penetration of three adhesives in proximal white-spot carious lesions: an in vitro study

Introducción: el tratamiento de lesiones interproximales de caries temprana representa un reto en la concepción moderna de la cariología y la operatoria. Como respuesta, además del diagnóstico temprano, emergen nuevos materiales para controlar laprogresión de la caries temprana. El objetivo de este estudio fue evaluar in vitro el grado de penetración de tres adhesivos: Excite (Ivoclar-Vivadent), Prime & Bond NT (Dentsply) y Single Bond (3M-ESPE), en el sellado de lesiones interproximales no cavitacionales de mancha blanca.Métodos: 117 premolares humanos extraídos con lesión interproximal de mancha blanca I CDAS-II 2 montados enyeso, simulando la situación en cavidad oral, fueron asignados aleatoriamente a uno de los tres grupos; se sellaron las lesiones con cadamaterial previamente mezclado con azul de metileno; se obtuvieron secciones longitudinales de 250 μm y se analizaron en fotografíasobtenidas bajo estereomicroscopía. Se valoró cubrimiento total de la lesión, profundidad histológica de la lesión en zonas y en micrómetros y, penetración máxima del adhesivo. Resultados: se analizaron 116 dientes. Se encontró cubrimiento total de la lesión en52,5%; 75% se ubicaron en la mitad interna del esmalte, con profundidad promedio de 854 ± 493 μm. La máxima penetración promedio del adhesivoen la lesión fue de 697 ± 412 μm. No hubo diferencias estadísticamente significativas entre grupos para las variables (Kruskal Wallis y correlación de Spearman; p > 0,05). Conclusión:estos tres adhesivos de baja viscosidad, con alto contenido de TEGDMA y HEMA,lograron el cubrimiento y la penetración de material para el sellado de lesiones tempranas de caries interproximal.

Introduction: the treatment of early proximal carious lesions represents a challenge to modern conceptions of cariology and operative dentistry. The possible solutions include, besides an early diagnosis, development of new materials to control early cariesprogression. The objective of this in vitro study was to evaluate the degree of penetration of three adhesives: Excite (Ivoclar-Vivadent), Prime & Bond NT (Dentsply), and Single Bond (3M-ESPE), in the process of sealing white-spot non-cavitated proximal lesions. Methods: 117 extracted human premolars with ICDAS 2 white-spot non-cavitated proximal lesions mounted on plaster, to simulate oral cavityconditions, were randomly sorted out in each of the three groups. The lesions were sealed with each of the materials previously mixed with methylene blue; longitudinal sections of 250 μm were obtained, and they were later analyzed on photographs taken with a stereomicroscope. These variables were evaluated: total lesion coating, lesion’s histologic depth (in micrometers), and the adhesive’s maximum penetration.Results: a total of 116 teeth were analyzed. Entire lesion coating was found in 52.5% of the cases; 75% were located in the enamel’s internal half, with an average depth of 854 ± 493 μm. The adhesive’s maximum average lesion penetration was 697 ± 412 μm. No statistical significant differences were found among the groups (Kruskal Wallis and Spearman correlation; p > 0.05). Conclusion: these three low-viscosity adhesives with high amounts of TEGDMA and HEMA effectively achieved covering and penetrating of the material for sealing early proximal carious lesions.
