    (2023) Ortuño Borroto, Duniel; Martínez Cardozo, Constanza Eugenia; Caneo Robles, Constanza Macarena
    Objectives: Previous studies have established an association between tooth loss and depression. However, longitudinal evidence is scarce and needs to be verified in other populations. The aim of this study was to examine the longitudinal association between the number of remaining teeth and incident depression at 2- and 4-years follow-up in individuals enrolled in the Maule cohort (MAUCO) in Chile. Methods: This prospective study used the information of individuals, aged 38 to 74 years, excluding those with depression at baseline. The number of remaining teeth at baseline was determined in four groups: “20 or more teeth”, “10 to 19 teeth”, “1 to 9 teeth” and “no natural teeth”. Depression was measured through the PHQ-9. Logistic regression was performed to calculate the odds ratios (OR) for incidence depression at both periods of follow-ups, adjusting for age, sex, educational attainment, diabetes mellitus II, and stressful events at follow-up. Also, we performed adjusted multinomial logistic models to analysis the association between the number of remaining teeth and depression severity. Results: In total individuals (n = 3335 at follow 1, n = 2461 at follow 2), all groups have ORs for incident depression above 1 considering 20 or more teeth as reference. In men, those with 10–19 teeth have 2.44 times higher odds of incident depression than those with 20 or more teeth (OR 2.44, CI 95% 1.33–4.50). Edentulous subjects at 4 years follow-up had 2.24 times higher odds of depression than those with more than 20 teeth (OR 2.24 CI 95%1.35–3.72). In women, the ORs (CI 95%) of incident depression were 2.56 (1.50–4.39), 1.56 (1.02–2.40) and 1.27 (0.90–1.81) for “none”, “1–9”, “10–19” respectively in comparison to the reference group. In edentulous individuals at baseline, the odds for each of the comparisons “mild vs no”, “moderate vs no”, “moderately severe vs no” and “severe vs no” were above 1, at both follow-ups. Conclusion: Individuals with less than 20 teeth in the mouth could had higher odds of incident depression at 2- and 4-years follow-up, with differences between men and women. Also, in our study, edentulism was associated with increased odds of incident depression at 4-years follow-up in women, and with higher levels of severity of depressive symptoms.

    Barreras y facilitadores en la aplicación del programa control con enfoque de riesgo odontológico (CERO) en el centro odontológico de la comuna de Macul
    (2022) Gálvez Kelly, Daniela; Ortuño Borroto, Duniel; Pontificia Universidad Católica de Chile. Facultad de Medicina
    La salud oral es un problema de salud pública de alta prevalencia. A pesar de los numerosos esfuerzos realizados por el Ministerio de Salud en Chile, la prevalencia de caries en la población permanece en niveles altos. Es por esto que se han realizado nuevas estrategias direccionadas a la prevención de enfermedad y promoción de la salud oral para mantener a la población sana. El programa “Control con enfoque de riesgo odontológico” (CERO) implementado durante el año 2017 tiene por objetivo individualizar factores de riesgo y mantener controles periódicos según este riesgo, sin embargo, aún no ha mostrado los resultados esperados en comunas como Macul. El objetivo de este estudio fue analizar la percepción de barreras y facilitadores de la implementación del programa CERO en odontólogos que ejecutan este programa en la comuna de Macul.Material y Método: Estudio descriptivo cualitativo con paradigma fenomenológico interpretativo. La muestra fue de 6 sujetos. Se recolectó la información mediante entrevistas individuales semiestructuradas, grabadas y transcritas en prorgrama Amberscript® e importadas a programa AtlasTi® para análisis de contenido.Resultados: Se analizó las respuestas de los entrevistados por separado, de los cuales se desglosaron los temas emergentes entregados por los odontólogos entrevistados. Se identificaron barreras como la programación de tiempo de cita insuficiente para los fines del programa y el desconocimiento de los alcances del programa en la población adolescente. Como facilitador se detectó la percepción de la mayoría de los entrevistados en que la cualidad empatía es necesaria en los odontólogos encargados de este programa. Como mejoras al programa los entrevistados sugirieron reforzar el trabajo con el resto del equipo de salud, refiriéndose a la necesidad de cooperación transversal en el cumplimiento de los objetivos de este programa. Discusión: La valoración del programa CERO en el centro odontológico de Macul fue positiva por parte de los odontólogos, sin embargo, recomiendan revisión de las condiciones de ejecución, como el tiempo programado para los controles, para poder alcanzar los objetivos del programa.

    Pérdida de dientes anteriores en adultos chilenos : nueva información epidemiológica según la última Encuesta Nacional de Salud 2016-2017 y análisis de la cobertura de los programas de reforzamiento de la APS dirigidos a la rehabilitación de piezas perdidas en adultos
    (2020) Berríos Vigneaux, Rodrigo; Ortuño Borroto, Duniel; Pontificia Universidad Católica de Chile. Facultad de Medicina
    Introducción: La pérdida de dientes anteriores tiene importantes consecuencias en la calidad de vida de los adultos, afectando la apariencia personal, empleabilidad y la capacidad de sociabilizar. En Chile, la Encuesta Nacional de Salud ENS 2016-17, fue el primer instrumento poblacional que midió pérdida de dientes anteriores. El objetivo general de esta investigación fue describir las prevalencias de pérdida de dientes anteriores y sus determinantes en población chilena mayor de 15 años. Un objetivo específico fue analizar la cobertura nacional para este problema de salud pública, a partir de una estimación de los principales programas odontológicos nacionales del sistema público de salud, que incluyen prótesis removibles en sus canastas de atención en la Atención Primaria de Salud (APS). Métodos: Para este estudio transversal, se ocupó el marco muestral de la ENS 2016-17 (n=5473 sujetos). Los análisis estadísticos se realizaron respetando el muestreo complejo y el uso de factores de expansión, utilizando el programa IBM® SPSS®. Las prevalencias de pérdida de dientes anteriores y OR fueron obtenidos ajustado por sexo, edad, NEDU y zona. Además, se determinaron las prevalencias de solución al problema de edentulismo anterior con el uso de prótesis removibles, y se calculó, mediante información censal, la cantidad de personas a las que no se resuelve el problema de edentulismo anterior pese a utilizar prótesis. Resultados: El riesgo de edentulismo anterior para ambos maxilares fue significativamente mayor en edades mayores, NEDU bajo y zona rural (valor-p<0.05). Para la variable sexo, el riesgo fue significativamente mayor en mujeres para el maxilar superior, no así para el maxilar inferior donde no hubo diferencias significativas (valor-p 0.286). La prevalencia de solución mediante prótesis fue superior al 90% para ambos maxilares, no obstante la cantidad de usuarios atendidos en los programas que ofrecen rehabilitación mediante prótesis en APS no alcanzan para resolver la necesidad de edentulismo anterior de la población chilena. Discusión: Existen grupos de riesgo los cuales requieren un mayor acceso a atención para mitigar brechas e inequidades. La actual cobertura de los programas de prótesis en APS no es suficiente para resolver el edentulismo anterior en Chile. Conclusión: El edentulismo anterior es un problema prevalente en Chile. Este problema debe considerarse en las políticas públicas de salud oral, y realizar reformas para mejorar la cobertura de los grupos de alto riesgo.

    Relationship between oral health and depression: data from the National Health Survey 2016–2017
    (2024) Palomer, Tomás; Ramírez Lobos, Valeria; Ortuño Borroto, Duniel
    Objective: To evaluate the relationship between oral health status, self-perception of oral health, and depression. Methods: This cross-sectional study included 2953 individuals that were ≥18 years of age and participated in the Chilean National Health Survey (NHS), 2016–2017. Information on oral, dental, and mental health, and the presence or absence of depressive symptoms was collected. Secondary data analysis was carried out using STATA and included logistic regression models adjusted for sex, age, and educational level. The analyses factored in the expansion weights to estimate representative prevalences of the entire population. Results: Participants experiencing frequent dental or prosthesis-related discomfort while speaking (OR: 1.57; 95% CI: 1.01–2.43) were related with exhibiting suspected depression. Removable upper denture users were at a higher risk of exhibiting suspected (OR: 2.04; 95% CI: 1.11–3.74) than those not using them. Participants diagnosed with depression in the past 12 months had a similar number of teeth (median=24) compared to those without depression (median=25) (OR: 0.99; 95% CI: 0.96–1.02). Conclusion: Experiencing dental or prosthesis-related difficulties in speaking is related to suspected depression or a diagnosis of depression. These findings highlight the importance of developing comprehensive healthcare approaches that consider mental health in the context of oral health.

    Tooth loss and depression: epidemiological evidence of causality from the Chilen population
    (2023) Ortuño Borroto, Duniel; Ferreccio Readi, Catterina; Pontificia Universidad Católica de Chile. Escuela de Medicina
    En este estudio, se evaluó la asociación entre pérdida dentaria y depresión con diferentes diseños y poblaciones en Chile. En el marco muestral MAUCO se realizó un análisis longitudinal, con regresiones logísticas binarias y multinomial. Se encontró que los individuos con 19 o menos dientes podrían tener mayor riesgo de depresión, con diferencias entre hombres y mujeres. El edentulismo se asoció a mayor incidencia de depresión a los 4 años de seguimiento, y con mayores niveles de severidad de los síntomas depresivos en mujeres. En los individuos edéntulos al inicio del estudio, el riesgo para cada una de las comparaciones "leve vs no", "moderada vs no", ”moderada severa vs no" y ”severa vs no" fue mayor comparado con aquellos con ≥ 20 dientes. Utilizando el marco muestral ENS 2016-2017, se realizó un análisis de mediación para evaluar el rol de las funciones orales en la asociación entre pérdida de dientes, incluyendo anteriores, y depresión en individuos de 15 años o más. El deterioro de las funciones orales fue un mediador en la asociación entre la pérdida de dientes y el autorreporte o la sospecha de depresión. La sensación de incomodidad al hablar o la incomodidad al comer fueron los mediadores más significativos.

    Validity of the self-reported number of teeth in Chilean adults
    (2019) Margozzini Maira, Paula; Berríos, Rodrigo.; Cantarutti Martínez, Cynthia; Véliz, Claudia P.; Ortuño Borroto, Duniel
    Abstract Background Clinical dental evaluations are considered complex and costly measurements that epidemiological surveillance studies of multiple simultaneous chronic diseases currently require, for example National Health Surveys (ENS). Accordingly, simpler and more affordable methods need to be validated. The aim of this study was to assess the validity of the self-report on the total number of teeth in the general Chilean adult population. Methods A substudy was conducted on ENS 2016–2017 participants. A stratified random sample of 101 of them was subjected to a telephone questionnaire. This information was then compared with the results obtained from the oral examination performed by a trained nurse during a home visit. Spearman correlations, intraclass correlation coefficients and the Bland-Altman method were used to analyse the data. Results In men, the average number of teeth recorded during the oral examination coincided with the number of teeth in the self-report (22 teeth). In women, the total teeth average was 18 and 19 teeth according to the examination and self-report, respectively. For the total number of participants, a strong and significant Spearman correlation was obtained (ρ = 0.93); in men and women, the Spearman correlation observed was also strong and significant (ρ = 0.90 and ρ = 0.96 respectively). The value of the intraclass correlation coefficient indicated a significant concordance (CCI = 0.96) in both men and women (CCI = 0.93 and 0.98 respectively). A tendency to greater correlation was observed as the number of teeth decreased. Conclusions The number of teeth self-reported by the subjects in this study correlated with the number of teeth recorded in the clinical examination.

Conclusions The number of teeth self-reported by the subjects in this study correlated with the number of teeth recorded in the clinical examination. Self-report is a valid method to determine the number of teeth in national health surveys.
