    Association between number of remaining teeth and incident depression in a rural Chilean cohort
    (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.

    Effects of hypotensive anesthesia compared to normotensive anesthesia in orthognathic surgeryEfectos de la anestesia hipotensora comparada con la anestesia normotensora en cirugía ortognática
    (2024) Dallaserra Albertini, Matías; Vargas Buratovic Juan Pablo; Campolo González, Andrés Francisco; Ríos Espósito, Nicolás; Nazar Jara, Claudio; Valladares Pérez, Salvador Rubén; Ortuño Borroto, Duniel
    Introduction: Orthognathic surgery is widely accepted for correcting dentofacial deformities. Due to the rich blood supply in the head and neck region, considerable bleeding can occur from the incised soft tissues and bone during orthognathic surgery. Hypotensive anesthesia is a method used in surgical practice by which blood pressure is decreased predictably and deliberately to reduce blood loss and improve surgical field. However, there is still uncertainty regarding its effectiveness and safety in orthognathic surgery. Methods: We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis, and generated a summary of findings table using the GRADE approach. Results and Conclusions: We identified three systematic reviews, including 11 studies overall, which are randomized trials. We concluded that hypotensive anesthesia may reduce intraoperative blood loss and may improve the quality of surgical field, however, the certainty of the evidence has been assessed as low. On the other hand, orthognathic surgery with HA may make little or no difference in surgical time (low certainty evidence). Finally, no studies were found that reported adverse effects or mortality.Introducción: La cirugía ortognática se encuentra ampliamente aceptada para la corrección de anomalías dentofaciales. Debido al importante suministro de sangre en la región de cabeza y cuello, puede ocurrir una considerable pérdida de sangre proveniente de los tejidos duros y blandos intervenidos durante una cirugía ortognática. La anestesia hipotensiva es un método utilizado en la práctica quirúrgica mediante el cual se disminuye de manera predecible y deliberada la presión sanguínea con el fin de reducir la pérdida hemática y mejorar el campo quirúrgico. Sin embargo, aún existe incertidumbre respecto a su efectividad y seguridad en cirugía ortognática. Métodos: Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un metanálisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. Resultados y Conclusiones: Identificamos tres revisiones sistemáticas, que en conjunto incluyeron 11 estudios primarios, todos ensayos aleatorizados. Concluimos que la anestesia hipotensiva podría reducir la pérdida de sangre intraoperatoria y mejorar la calidad del campo quirúrgico, pero la certeza de la evidencia es baja. Por otro lado, el uso de anestesia hipotensiva podria podría resultar en poca o nula diferencia en el tiempo quirúrgico (certeza de la evidencia baja). Finalmente, no se encontraron estudios que reportaran efectos adversos o mortalidad.

    Multimorbidity and tooth loss: data from Chilean National Health Survey 2016–2017
    (2024) Santos-López, Matías; Gómez San Martín, Priscila Gabriela; Margozzini Maira, Paula; Ortuño Borroto, Duniel
    Background Oral diseases are a significant global public health challenge. Current evidence indicates that several chronic conditions are individually associated with tooth loss. People are living with more than one chronic condition, known as multimorbidity (MM). Considering the common risk factors for oral and chronic diseases, this study aimed to evaluate the association between MM and tooth loss in the Chilean population. Methods Cross-sectional study with secondary data from the latest Chilean National Health Survey (ENS 2016-17). The number of remaining teeth was classified into four groups: functional dentition (≥ 20 remaining teeth), moderate tooth loss (10 to 19), severe tooth loss (1 to 9), and edentulism (0). MM was defined based on the number of chronic conditions as a binary variable (MM≥ 2) and as a 4-level categorical variable (MMG0−G3), G0: none, G1: 1, G2: 2–4, and G3: ≥5 conditions. Stratified analysis by age group (< 65, ≥ 65 years) was performed. Mean and SD were calculated for crude and adjusted remaining teeth. Significance level was set to 0.05. Prevalence ratios were estimated with Poisson regression models with robust variance, crude and adjusted for sex, age, geographic area, and educational level. Logistic regressions models were fitted to calculate odds ratios as a sensitivity analysis. Results Of 4,151 adults aged 17–98, 54.9% had MM and the prevalence of moderate, severe tooth loss and edentulism was 25.4%, 6.9% and 4.8% respectively. Adults aged ≥ 65 years with MM≥ 2 were 1.66 [1.04–2.66] times more likely to have severe tooth loss than those without MM. Adults aged < 65 years with MMG3 were 1.76 [1.12–2.77] times more likely to have moderate tooth loss and 2.55 [1.02–6.36] times more likely to have severe tooth loss than those without MM. Conclusions In this study, we found statistically significant associations between the number of chronic conditions and moderate/severe tooth loss in both analyzed age groups. These findings highlight the need to provide oral health care for adults with multimorbidity using a person-centred model and to seek strategies to prioritize health care.

    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.

    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.

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.
