    (Operative Dentistry, 2019) Urzúa, Iván; Cabello, Rodrigo; Marín, Paulina; Ruiz, Begoña; Jazanovich, Diego; Mautz, Claudia; Lira, Mauricio; Sánchez, Jenny; Rodríguez, Gonzalo; Osorio, Sylvia; Ortiz, María Eugenia
    Detection and management of posterior approximal caries lesions are still problematic. Inspection of approximal surfaces is challenging, and bitewing radiographs are used when direct vision is not possible. Unfortunately, there is no definite radiographic appearance to identify lesion cavitation with absolute certainty. Many lesions detected radiographically within the outer half of dentin are not cavitated, often resulting in unnecessary restorative treatment. Our study compared radiographic depth of approximal caries lesions with presence of cavitation in adults using visual inspection following temporary tooth separation (TTS). We conducted this observational descriptive cross-sectional study at two dental schools in two cities in Chile. Clinicians were unaware of radiographic depths of lesions and examined 147 participants (57.3% female and 42.7% male) following TTS. Using the common classification system that consists of E0 (no lesion), E1 (lesion within the outer half of enamel), E2 (lesion within the inner half of enamel), D1 (lesion within the outer third of dentin), D2 (lesion within the middle third of dentin), and D3 (lesion within the inner third of dentin), a trained dentist evaluated all the processed films. Cavitation was detected in only three sites (0.22%) within the E0 category, seven sites (3.41%) in E1, five sites (14.8%) in E2, four sites (14.8%) in D1, six sites (50%) in D2, and eight sites (61.5%) in D3. Considering that restorative treatment should be indicated strictly for cavitated lesions, our findings support indication for restorative treatment for D3 lesions and the rationale for TTS for D1-D2 caries lesions to allow direct visual inspection to determine whether there is surface cavitation.

    “Nadie está preparado para escuchar lo que vi” : atención de salud mental de refugiados y solicitantes de asilo en Chile
    (Instituto de Salud Colectiva, Universidad Nacional de Lanús, 2020-01) Carreño, Alejandra; Blukacz, Alice; Cabieses, Baltica; Jazanovich, Diego
    This article analyzes the results of a descriptive, qualitative study carried out in 2018 on the mental healthcare needs of Latin American refugees and asylum seekers in Chile, through the perspectives of refugees and asylum applicants (n=8), healthcare professionals responsible for delivery of care (n=4), and members of civil society organisations involved in this area (n=2). Our findings indicate that despite Chile’s commitment to international treaties in this regard, little has been achieved in safeguarding the right to access to mental health care, understood as part of the universal right to health care access. This article documents barriers to mental health care access for migrants applying for asylum and refugee status. Post-migration stress factors may also increase the risk of emotional disorders within this group of people. Mental healthcare providers and teams are often not equipped with the tools to deal with the psychological consequences arising from the situations of violence and persecution associated with forced migration. Our study discusses the need to strengthen the link between mental health care – as a fundamental human right – and the right to international protection.

    Patient experience and non-surgical periodontal therapy in a postgraduate periodontal training program: A qualitative study
    (Sociedad de Periodoncia de Chile, Sociedad de Implantología Oral de Chile; Sociedad de Prótesis y Rehabilitación Oral de Chile; Sociedad Chilena de Odontopediatría y Sociedad de Ortodoncia de Chile, 2022-04) Prieto, Diego; Vásquez, Pamela; Ortega, Miguel Ángel; Cáceres, Felipe; Meléndez, Catalina; Nally, Mauricio; Jazanovich, Diego
    Objective: To explore patient experience for non-surgical periodontal therapy using phenomenography. Methods: This qualitative study was performed in a postgraduate specialist training program in periodontics. Patients reported their experiences through in-depth interviews in order to recognize the impact of non-surgical periodontal therapy on their quality of life and their satisfaction. A homogeneous sampling procedure was used, establishing redundancy after the fifteenth interview. Interviews were audio recorded, transcribed and analyzed by three researchers who codified the answers into categories to determine the emerging topics. Results: The core emerging themes were: (i) lack of information about periodontal disease; (ii) experience during treatment; (iii) treatment implications; and (iv) clinician–patient relationship. Conclusions: Patients seem to have limited knowledge about periodontal diseases. Reasons for attendance mainly include bleeding gums, tooth mobility, and aesthetic problems. Therapy can generate pain, fear, and is considered invasive, whereas dentine hypersensitivity may occur post-operatively. Despite this, patients would be willing to undergo treatment again and were generally satisfied with the level of care and treatment received.

    Preferencias y percepciones de feedback en estudiantes de odontología
    (Universidad Finis Terrae (Chile) Facultad de Odontología, 2021) Vidal Espinoza, Loreto; Jazanovich, Diego
    Introducción: Dentro de la educación dental, se propone investigar sobre el feedback clínico y su vinculación con el aprendizaje de los estudiantes de pregrado de odontología. A través de la búsqueda en la literatura científica y una revisión metodológica, que incluya referencias relacionadas con la odontología. El término anglosajón” feedback” significa “retroalimentación” en español. Entre los propósitos de una efectiva entrega de feedback al estudiante están el generar un nivel de satisfacción entre el estudiante y el docente, mejorando la relación por “fomentar un aprendizaje significativo y profundo, además de potenciar un clima propicio para el aprendizaje”. Algunas de las barreras que impiden un feedback efectivo son la falta de información específica entre el rendimiento observado de un estudiante y un estándar dado. Asimismo, el desconocimiento de los estudiantes sobre los resultados de aprendizaje, competencias, u objetivos curriculares propuestos para mejorar su rendimiento obstaculiza este diálogo de feedback más aún en casos de estar acompañado por docentes no adecuadamente capacitados para elaborar e implementar estrategias de entrega de feedback efectivo lo cual generaría indudablemente un debilitamiento en el aprendizaje. Objetivos: Es determinar cuáles son las preferencias y percepciones de feedback en los estudiantes de pregrado de odontología UFT. Metodología: Diseño del estudio Observacional, descriptivo transversal. Población y muestra son los estudiantes matriculados de cuarto y quinto año (aproximadamente 100). El universo por estudiar comprendido a todos los estudiantes de pregrado de odontología de la UFT de ambos sexos, quienes cursan cuarto y quinto año que cumplan los criterios de inclusión y exclusión. El instrumento de recolección de datos fue una encuesta Resultados: El análisis de los componentes principales de la encuesta preferencias y percepciones de feedback en los estudiantes de odontología UFT. Comprendió datos demográficos, tales como el sexo de los participantes son masculino 31%, femenino 69% (M=1,69 SD=0,467). Las edades de los encuestados oscilaron entre los 21 y 35 años (M=24,5 años. SD=2,36) con un 53% entre 23-24 años. El año académico de los estudiantes el 54% cuarto año, 46% quinto año de odontología (M= 4.6 SD=0,502). La situación académica de los estudiantes que reprobaron asignatura durante su trayectoria es 69% y los que no reprobaron 31% (M=1.31 SD=0.467). Además, los resultados de las preferencias de feedback destacan el valor que le asignan los estudiantes al feedback para su aprendizaje y su futuro desempeño profesional.

    Rest seat preparation for removable partial dentures: does professional dental practice reflect undergraduate teaching?
    (American Journal of Multidisciplinary Research & Development, 2021-02) Fernández, Enrique; Padilla, Paula; Jazanovich, Diego; Albers, Daniela; Acosta, Hernán; Benavides, Carolina; Sarabia, Alexander
    Statement of problem. Dental publications worldwide have reported discrepancies between how removable partial dentures are taught at undergraduate level and how these clinical procedures are performed extramurally, particularly regarding rest seat preparation. Considerable gaps have already been documented between undergraduate teaching and actual implementation in dental practice. Purpose. The aims of this study are to evaluate the presence of mouth preparation (cingulum and/or occlusal rest seats) before fabrication of cast removable partial dentures and explore causes that may contribute to and result in discrepancies between what is taught at undergraduate level and what is later on practiced by qualified dentists. The tested null hypothesis was that there is no difference between the frequency of working casts with and without rest seat preparations evaluated by dental laboratories in our study. Material and Methods. 103 laboratories were identified through an internet search strategy. Each laboratory was subsequently telephoned to determine if they provided cast metal removable partial dentures. Only 36 laboratories were shortlisted and out of these only 24 agreed to take part in our study. Three establishments did not fulfil our inclusion criteria leaving an overall 21 dental laboratories to participate in this study. Laboratory staff were calibrated to inspect, detect, and record the presence or absence of cingulum and/or occlusal rest seats in working casts before fabrication of metal frameworks for removable partial dentures over a one-month period. All 21 calibrated laboratories were given a proforma spreadsheet to record the presence or absence of at least one rest seat preparation per model before fabrication of metal frameworks.Statistical analysis was performed with StataCorp softwareby using the binomial probability test of 1 sample. Results. A total of 1,512 working casts were inspected and 630 (41.70%)displayed rest seat preparations(P< 0.001). The remainder 58.30% of casts examined (882) had no rest seat preparations. Only two laboratories recorded over 80% of casts with rest seat preparations and eight laboratories recorded rest seat preparations in 20% of working casts, or less. Conclusions. Lack of rest seat preparation highlights a rather large proportion of dentists performing inadequate mouth preparation before removable partial denture fabrication. Interacting factors might include shortcomings in undergraduate curricular design for removable partial prosthodontics and a contemporary socioeconomic and cultural burden on the dental profession. These implications for dental education beg the question of how to implement and deliver curricular content emphasizing duty of care and ethics for future generations of competent dental practitioners. CLINICAL IMPLICATIONS The results from this study confirm a vast majority of dental practitioners do not perform suitable pre-prosthetic mouth preparation with regard to rest seats.This has a direct clinical impact on removable partial prostheses hindering successful oral rehabilitation, which is most likely to result in further damage to remaining hard and soft dental tissues.
