Dentoalveolar, periodontal and skeletal effects of maxillary expansion techniques assisted by temporary anchorage devices compared with conventional protocols in growing patients with transverse maxillary deficiency: A systematic review and meta-analysis.

OBJECTIVES: To synthesise the dentoalveolar, periodontal and skeletal changes that occur when using maxillary expansion techniques assisted by temporary anchorage devices compared to conventional protocols. METHODS: Five databases and grey literature were consulted, up to December 2023, focusing on intervention designs and excluding other type of studies. The quality assessment was conducted by using the adaptation for orthodontics of the CONSORT statement, the guidelines for reporting non-randomised studies, the RoB-2 tool, and the ROBINS-I tool. A descriptive summary and meta-analysis using RevMan 5.4 were performed. RESULTS: Nine clinical trials were included (n=377 patients, mean age 13.2±0.6) with a diagnosis of transverse maxillary deficiency. The analysed studies showed qualitative dentoalveolar and periodontal changes after expansion, which were greater on the maxillary first premolars in tooth-borne appliances. Meta-analyses for some effects were included from two studies (n=64); patients who used tooth-borne appliances had greater effects of buccal intercoronal width between the premolars with statistically significant differences (Std Mean difference 2.34; 95% CI: 0.04-4.65 p=0.05). Conversely, those patients who used bone-borne or hybrid appliances had greater effects of buccal intercoronal width between molars with statistically significant differences (Std Mean difference -0.64; 95% CI: -1.38-0.10; p=0.09). CONCLUSIONS: According to the studies analysed, all measurements increased in the intervention groups after expansion. Quantitative analyses show different findings at dentoalveolar level when tooth-borne, bone-borne or hybrid appliances are considered. Nevertheless, the results should be taken with caution due to the heterogeneity of the studies. The protocol was registered at PROSPERO (CRD42021283170), with no funding to report.

Calidad de vida y factores condicionantes en personas con Labio Fisurado y Paladar Hendido No Sindrómico (LPHNs): experiencias de familiares, pacientes, y personal de salud / Quality of life and conditioning factors in people with Non-syndromic Cleft Lip and Palate (NSCLP): experiences of family members, patients, and health personnel

Objetivo: comprender las percepciones sobre calidad de vida (CV) y sus factores condicionantes en personas con Labio Fisurado y Paladar Hendido No Sindrómico (LPHNs), desde la experiencia de las personas con esta condición, y desde sus familias y equipo de salud. Métodos: estudio cualitativo con perspectiva fenomenológica. Se realizaron entrevistas semiestructuradas a seis individuos que cumplían los criterios de participación (4 mujeres) y seis familiares (esposos, hermanos, padre/madre) mediante un guion estructurado. Esta información se complementó con una entrevista a un ortodoncista con experiencia en atención a estos individuos y un grupo focal con laparticipación de profesionales de la salud. Se realizó análisis de contenido cualitativo y estrategias de reducción fenomenológica desde los discursos experienciales de la población participante. Se contó con aprobación ética e institucional. Resultados: se encontraron cuatro categorías principales desde la experiencia de las personas con LPHNs que involucran diferentes perspectivas de los participantes del estudio: 1) concepto de CV y sus factores condicionantes, 2) experiencia de vida con la condición de LPHNs; 3) experiencia durante el tratamiento integral para la condición de LPHNs; y 4) expectativas generales. Todas estas categorías reflejan la historia de vida, los elementos individuales y sociales, y las dificultades propias de su condición. Conclusiones: existen factores individuales, sociales y contextuales que inciden en la CV de los pacientes con LPHNs. Esto implica un abordaje intersectorial y multidisciplinario que permita la generación de políticas en salud y estrategias de tratamiento acordes a las necesidades individuales y colectivas de estas personas.

Objective: Understand the perceptions and experiences about quality of life (QOL) and their conditionants in people with Non-syndromic Cleft Lip and Palate (NSCLP), from the experience of people living with this condition, and from their families and health personnel. Methods: A qualitative study with phenomenological perspective was conducted. Six individuals and relatives (partner, siblings, parents) were interviewed. This information was complemented by an interview with an orthodontist who works with people with NSCLP and a Focus Group with the participation of health personnel working in a Specialized Foundation focused on these individuals. Qualitative content analysis and phenomenological reduction strategies were carried out to address the main themes extracted from the discourses of the participating population. Ethical and institutional approval was obtained. Results: Four main categories of the experience of people with NSCLP were found that involve the different perspectives of the study participants: 1) concept of QOL and its conditioning factors, 2) life experience with the condition of NSCLP; 3) experience during comprehensive treatment for NSCLP condition; and 4) general expectations. All these categories reflect the life history, the individual and social elements, and the difficulties inherent to their condition. Conclusions: there are individual, social, and contextual factors that affect the QOL of people living with NSCLP. This situation implies an intersectoral and multidisciplinary approach that allows the generation of health policies and treatment strategies according to the individual and collective people's needs.

Frequency of symptoms and the associated factors of eating disorders in a group of dental students in Medellín, Colombia.

BACKGROUND: Eating disorders (EDs) are considered a public health problem. Scientific research has focused on teenagers due to their higher prevalence in this population. However, other groups, such as university students, may be exposed to suffering from EDs due to their academic, social and personal characteristics. Identifying the magnitude of EDs and the associated characteristics may impact the generation of prevention strategies. OBJECTIVES: The aim of the present study was to establish the prevalence of the risk of EDs (anorexia nervosa (AN) and bulimia nervosa (BN)) and the associated factors in dental students at the University of Antioquia, Medellín, Colombia.. MATERIAL AND METHODS: A cross-sectional study was conducted on 278 students (76 males, 202 females) with the use of a Google-Forms survey. The validated Spanish version of the Eating Attitudes Test-26 (EAT-26) and the Sick, Control, One Stone, Fat, Food (SCOFF) questionnaire were used. Other recorded variables included sociodemographic data, coronavirus disease 2019 (COVID-19)-related factors, health, and social support (the Duke-11 profile). The bivariate analysis of the risk of EDs was conducted according to different variables (95% confidence interval (CI)), followed by the logistic regression models adjusting for different variables (adjusted prevalence ratio (aPR) and 95% CI). RESULTS: According to EAT-26, the risk of EDs was 27.6% (18.8-38.6) for males and 28.7% (22.9-35.3) for females. However, differences between males and females were higher when the SCOFF questionnaire was applied (males: 6.6% (2.8-14.5); females: 22.3% (17.1-28.5); p < 0.01). According to the SCOFF instrument, after adjusting for sociodemographic and health variables, women were more likely to report the symptoms of EDs (aPR: 2.20; 95% CI: 1.06-4.57). Women receiving information from social networks were more likely to report the symptoms of EDs (aPR: 1.85; 95% CI: 1.19-2.88). Multivariate models showed that women reporting poor self-rated health and some symptoms during the mandatory confinement caused by the COVID-19 pandemic were more likely to report the symptoms of EDs. CONCLUSIONS: A higher risk of EDs was found in dental students. Healthcare, psychological and/or psychiatric interviews, and educational/early prevention strategies are required.

Introducción: las mujeres y las personas trans que han ejercido el trabajo sexual se encuentran vulneradas puesto que son víctimas de discriminación por su condición laboral, por su género y por los riesgos que acarrea esta labor, y esto impacta en su situación de salud. Este estudio tuvo como objetivo conocer las percepciones sobre salud (física, mental y bucal) en cuatro mujeres que ejercen la prostitución en Medellín, a partir de sus experiencias de vida y aquellas relacionadas con su contexto social. Métodos: se realizó una investigación cualitativa con enfoque etnográfico para analizar las situaciones mencionadas de acuerdo con el objetivo general. Se contó con la participación de cuatro mujeres: dos de nacionalidad venezolana y dos de nacionalidad colombiana; se llevaron a cabo entrevistas semiestructuradas. Se realizó análisis de contenido cualitativo, lo cual permitió la generación de cuatro categorías (salud mental, salud bucal, salud general y calidad de vida). Resultados: sus discursos permitieron elucidar la conexión entre las condiciones de vida y la situación de salud. La falta de oportunidades laborales, un proceso migratorio de profundos cambios económicos y sociales, y una Colombia con inequidades y barreras de acceso a servicios de salud y sociales, son procesos determinantes de orden general, particular y singular de las precarias condiciones de salud bucal y general. Conclusiones: la población participante se encuentra en situación de vulnerabilidad social y de salud, lo cual evidencia la necesidad de políticas públicas y estrategias basadas en la realidad social que contribuyan a generar equidad en salud.

Introduction: women and trans people who have engaged in sex work are triply vulnerable since they are victims of discrimination due to their employment status, their gender, and the risks that this work entails, this impacts their health situation. This study aimed to know the perceptions about health (physical, mental, and oral) of four women who work in prostitution in Medellin, based on their life experiences and those related to their social context. Methods: qualitative research with an ethnographic approach was conducted to analyze the situations mentioned. Four women participated, two Venezuelans and two Colombians, and semi-structured interviews were conducted. Qualitative content analysis was performed, which allowed the generation of four categories (mental health, oral health, general health, and quality of life). Results: her discourses made it possible to elucidate the connection between the living conditions and the health situation. Lack of job opportunities, a migratory process of profound economic and social changes, and a Colombia with inequities and barriers to access to health and social services are determining processes of a general and singular order of the precarious conditions of oral health and general. Conclusions: the participating population is in a situation of social and health vulnerability, which shows the need for public policies and strategies based on the social reality that contribute to generating equity in health.

Oral health-related quality of life in a group of patients with rheumatoid arthritis.

BACKGROUND: Rheumatoid arthritis (RA) and periodontitis (PD) are chronic diseases that are associated with connective tissue and bone destruction, which affects the quality of life of the people suffering from these conditions. The identification of social conditions and the determinants of RA and PD would permit the elaboration of policies and strategies based on social reality. OBJECTIVES: The aim of the present study was to identify the relationship between oral health-related quality of life (OHRQoL) and the indicators of general health and oral health in patients with RA. MATERIAL AND METHODS: A cross-sectional study involving 59 patients with RA was conducted between 2019 and 2020. Demographic, general health, periodontal, and oral health parameters were collected. In addition, the Oral Health Impact Profile-14 (OHIP-14) questionnaire was administered to each patient. A description of the OHIP-14 dimensions according to different variables was performed. The relationship between OHRQoL and general/oral health indicators was analyzed with logistic and linear regression analyses. RESULTS: The highest OHIP-14 scores were found in people that were 60 years of age and over, single, had low educational achievements, a low socioeconomic status, were unemployed, and had no health affiliation. In the adjusted model, the prevalence of the impact on OHRQoL was 1.34 (1.10-5.29) times greater in those with erosive RA than in those without, and 2.22 (1.16-29.50) times greater in those who self-reported morning stiffness. Regarding the stage of PD, those with stage IV had a prevalence of the impact on the OHRQoL of 70%, an average extent of 3.4 ±4.5 and a severity score of 11.5 ±22.0, with statistically significant differences. CONCLUSIONS: The dimensions with the greatest impact on the OHRQoL of patients were physical pain, discomfort and psychological disability. The type of RA and the severity of PD are indicators of worse scores on the OHRQoL scale.

Understanding the Quality of Life and Its Related Factors in Orthodontics Postgraduate Students: A Mixed Methods Approach.

This study analyzed the academic, sociodemographic, and labor conditions related to the quality of life (QOL) of orthodontics postgraduate students in Colombia. A mixed study (explanatory sequential design) was conducted. An online cross-sectional survey (n = 84; 64.3% females) was carried out with sociodemographic, academic, social support, health, labor, and QOL (WHOQOL-BREF) variables. Descriptive, bivariate analyses, and multivariate linear regression were performed. Focus groups (FGs) delved into aspects of relevance regarding QOL and determinants, through qualitative content analysis and triangulation of information. The median score in the four WHOQOL-BREF dimensions surpasses 50 points, with the highest score being in the psychological dimension (62.5 ± 16.7). According to the multivariate linear regression models, the variables significantly associated with QOL scores were playing sports, being married/living together, normal BMI, low social support, and medium/low socioeconomic status. The qualitative results explained the determinants of QOL in the personal, academic, and social dimensions of the participants. The discourses showed that the postgraduate course represents a resignification of their life, where their QOL is affected by the difficulties of their academic development, by the difficulty of reconciling the personal academic load with their affective, work, and social life, and by the stress they experience in their staff process. In conclusion, the participants' QOL was moderate and affected by different factors. The findings highlighted the importance of mental health promotion and well-being strategies in students of orthodontic postgraduate training programs in Colombia for improving QOL.

Peruvian children toothbrushing during the COVID-19 pandemic.

Background: Toothbrushing is a convenient, inexpensive, widespread and culturally accepted method, resulting in an ideal public health outcome. This study aimed to determine the impact of the COVID-19 pandemic on toothbrushing in Peruvian children. Methods: This was a cross-sectional study conducted using a database of children aged 0 to 11 years, with a final sample of 39,124 participants, 15,974 in 2019 (62.03%) and 7088 in 2020 (55.54%). General toothbrushing, daily toothbrushing and minimum frequency of two times a day were dependent variables; the year was considered as the independent variable. In addition, other covariates such as geographical landscape, area of residence, place of residence, altitude, wealth index, health insurance cover, sex and age. Descriptive, bivariate and multivariate statistical analyses were applied. Results: General toothbrushing was 96.19% (n=51 013), daily toothbrushing was 87.47% (n=42 246) and minimum toothbrushing two times a day was 84.53% (n=33 957). In multivariate form, the year presented a negative association with daily toothbrushing (RPa: 0.97; CI95%: 0.96-0.98; p<0.001) and minimum toothbrushing two times a day (RPa: 0.97; CI95%: 0.95-0.98; p<0.001), adjusted for the previously associated co-variables. Conclusions: The year 2020 of the COVID-19 pandemic negatively impacted daily toothbrushing and minimum twice-daily toothbrushing of Peruvian children.

A Comprehensive Mixed Methods Approach for Studying the Quality of Life of Colombian Periodontists.

This study analyzed the association of the sociodemographic, labor, and health conditions on the quality of life (QOL) of the periodontists in Colombia. A mixed study (explanatory sequential design) was conducted. The first quantitative phase was carried out by a cross-sectional survey (n = 187; 60.4% females). Variables: sociodemographics, labor, and health conditions, QOL (WHOQOL-BREF). Normality tests, descriptive statistics, and bivariate analyzes were performed. Factors associated with QOL were established using multivariate linear regression. A second qualitative phase with two focus groups (FGs) delved into those aspects of relevance, through qualitative content analysis and triangulation of information. The multivariate linear regression analysis showed that the factors associated with the QOL scores were in the case of men and negatively (QOL decreases): having low social support (p < 0.001), reporting poor mental health (p < 0.01). For women, QOL scores were negatively associated with low social support (p < 0.001), reporting poor general and mental health (p < 0.01), having greater stress at work (p < 0.05), having a temporary contract (p < 0.05), and living in a medium or low socioeconomic status (p < 0.05). The analysis of the FG allowed us to understand how QOL is permeated by the social context. The specialization of periodontics has generated a change in living conditions, and an adaptation to the workplace that allows them to gain recognition and a higher QOL. In conclusion, the QOL of periodontists is defined in subjective terms (standards) and related to social and labor conditions. Follow-up and evaluation strategies of the general conditions of these clinical specialists in Colombia are required.

Quality of Life and Related Factors in Specialists on Pediatric Dentistry and the like Graduated from a Public University: A Mixed Methods Approach.

This study aims to analyze the factors associated with the quality of life (QOL) in pediatric dentistry specialists and the like, graduated in a public university between 1972 and 2018. A mixed study (explanatory sequential design) was conducted. Firstly, a cross-sectional survey (n = 62, 51% women) was carried out and complemented with three focus groups (FGs) and four semi-structured interviews (SIs). Descriptive statistics, bivariate analyzes and non-parametric correlation were calculated. A multivariate linear regression was carried out to establish the factors associated with QOL. In FGs, the concept of QOL and the factors that influence it was investigated, by following a qualitative content analysis and later the information was triangulated. The median QOL scores surpass 62 points. The multivariate analysis showed that the factors exerted the greatest influence negatively (decreases the QOL score) were: having an independent or service provision contract (p < 0.05), low social support (p < 0.001), job dissatisfaction (p < 0.01), poor mental health (p < 0.01), self-perceived poor general health (p < 0.01). The information from the FGs and interviews allow to establish three categories of analysis: (1) QOL and health: multiple facets, determinants, and dimensions; (2) encounters and disagreements between the postgraduate curricular training proposal and the labor and social field of the specialist; (3) an itinerant clinical specialization. The QOL of participants is considered good in general terms and is conditioned by subjective factors, the social environment, and the conditions of their professional work.

Impact of the COVID-19 pandemic on the timing of dental care in elderly peruvians.

In Peru, there is low dental service use among older adults, in addition to a social gradient for use. Furthermore, the COVID-19 pandemic triggered complex scenarios characterized by inadequate access to health services, with greater impact on vulnerable population groups such as the elderly. The aim of this study was to determine the impact of the COVID-19 pandemic on the time since last dental care visit among elderly Peruvians. It was a cross-sectional study conducted on a population of 5247 respondents in 2019, and 5066 respondents in 2020. The study considered the answers of people who responded to the question on the last time they had received dental care, extracting a total 4045 subjects for 2019 and 3943 for 2020. The dependent variable was time since last dental care measured in years, while the variables on health, geographic and sociodemographic characteristics were grouped within three dimensions. A descriptive bivariate and multivariateanalysiswasapplied by means of multiple linear regression to analyze the behavior of the variables. Time since the last dental care visit was 7.93 years (SD=8.03) in 2019 and 7.94 years (SD=7.28) in 2020. A hierarchical multiple linear regression analysis was performed, where no variable in the 2019 model was significant; while for 2020, health, geographic, and sociodemographic characteristics variables were significant. In the analysis where the 'year' variable becomes independent, only model 4, which considers all variables, was valid (p=0.018). The variables 'area of residence' and 'wealth index' were also significant. To conclude, the 2020 pandemic year for COVID-19 had no impact on the time since last dental care visit among elderly Peruvians, though factors such as area of residence and wealth index were found to be associated with the time since last dental care visit.

En Perú, los adultos mayores presentan un bajo uso de los servicios odontológicos, además de percibirse una gradiente social para su utilización. Adicionalmente, la pandemia por COVID-19 desencadenó escenarios complejos, caracterizados por un inadecuado acceso a los servicios de salud, que afectó con mayor énfasis a grupos poblacionales vulnerables, como las personas en edades extremas. El objetivo de este estudio fue determinar el impacto de la pandemia por COVID-19 en el tiempo de atención odontológica en adultos mayores peruanos. Estudio transversal con población de 5247 encuestados para el 2019 y 5066 para el 2020. Se consideraron los registros de quienes respondieron a la pregunta sobre el tiempo desde su última atención odontológica, extrayéndose del 2019 un total de 4045 y para 2020, 3943 sujetos. La variable dependiente consistió en el tiempo desde la última atención odontológica medido en años; mientras que dentro de tres dimensiones,seagruparon a lasvariables sobre características de salud, geográficas y sociodemográficas. Se aplicó un análisis descriptivo, bivariado y multivariado, donde el tiempo desde la última atención odontológica en el año 2019 fue de 7.93 años (DE=8.03) y en el 2020 fue de 7.94 años (DE=7.28). Se realizó un análisis de regresión lineal múltiple jerárquica, donde ninguna variable del modelo 2019 fue significativa; mientras que para 2020, las variables características de salud, geográficas y sociodemográficas si lo fueron. Al análisis, donde el año pasa a ser independiente, sólo el modelo 4, que considera todas las variables fue válido (p=0.018); asimismo, el área de residencia e índice de riqueza presentaron significancia estadística. Para concluir, en el año 2020 la pandemia por COVID-19 no impactó en el tiempo de atención odontológica en adultos mayores peruanos, sin embargo, factores como área de residencia e índice de riqueza si presentaron asociación con el tiempo desdelaúltimaatención.

A Scoping Review about the Characteristics and Success-Failure Rates of Temporary Anchorage Devices in Orthodontics.

This study synthesized the scientific evidence concerning the main characteristics of the Temporary Anchorage Devices (TADs) used in orthodontics and reported the success-failure rates during treatment. For that means, this scoping review collected articles from previous research. A complementary search was carried out in the databases PubMed-MEDLINE, Scopus, LILACS, and EMBASE, focusing on original studies published from 2010 to 2020. We analyzed the main characteristics of the publications. As a result, 103 articles were included. Most of the research was conducted among different groups, who needed TADs principally in the maxilla and an interradicular location between the second premolar and first molar. AbsoAnchor, Dentos Inc., Daegu, Korea, was the most used brand of TADs. The most common characteristics of the devices and biomechanics were a diameter and length of 1.6 mm and 8 mm, a self-drilled system, a closed technique for placement, immediate loading, and forces that ranged between 40 and 800 g. Of the studies, 47.6% showed success rates ≥90%. In conclusion, high success rates were found for TADs, and differences were found according to sociodemographic and clinical variables. The studies showed variability in methodological design, and scientific publications were concentrated in certain countries. We recommend further scientific research on TADs using more standardized designs.

General Labor Well-Being in Latin American Dentists during the COVID-19 Pandemic.

This study aimed to determine the general labor well-being of Latin American dentists according to sociodemographic characteristics during the COVID-19 pandemic. A cross-sectional study was conducted in a final sample of 2214 participants from 11 countries. A validated online questionnaire on general work well-being was used (data collection period from 1 June to 10 July 2021), containing two dimensions: psychosocial well-being and collateral effects. The sociodemographic characteristics of the dentists and their perception of the economic impact of the pandemic were also recorded. A multivariate linear regression analysis was performed (hierarchical regression model) to evaluate the joint effect of the explanatory variables on labor well-being and the changes in the variance between each model. A score of psychosocial well-being of 233.6 + 40.2 and collateral effects of 45 + 20.1 was found. Psychosocial well-being was associated with sex, country of origin, academic training achieved, type of dental activity, and perceived impact during the pandemic (p < 0.05). Somatization was frequently manifested through back pain (88.2%) and muscular tensions (87.2%). Women, those who worked 41 or more hours and had between 1 to 15 years of professional experience presented a greater collateral effect (p < 0.001). The impact of the COVID-19 pandemic a year and a half after it began on the labor well-being of Latin American dentists was evidenced with important interactions with social characteristics.

Impact of COVID-19 on the future career plans of dentists.

BACKGROUND: It is important to complement the scientific literature with the data regarding the impact of the coronavirus disease 2019 (COVID-19) pandemic on the social, work and health practices as well as on the daily life of dentists, and to promote adequate public policies. OBJECTIVES: The aim of the study was to explore the impact of the COVID-19 pandemic on the career plans of dentists in Colombia. MATERIAL AND METHODS: As part of global research on the impact of COVID-19 on dentistry, a crosssectional survey was administered via digital media to dentists in Colombia. The validated questionnaire included inquiries regarding sociodemographic variables, the perception of the risk of contagion with COVID-19 and the impact of COVID-19 on the dentists' career plans. The variables were summarized in absolute and relative frequencies, and a binomial logistic regression analysis was carried out to evaluate the impact of COVID-19 on career plans according to the independent variables. RESULTS: A total of 5,370 dentists answered the survey (women: 3,878; median age: 45 years; response rate: 16.85%). Most of the dentists (96%) believed that COVID-19 infection was a risk for them and 81.96% reported that the COVID-19 pandemic had some impact on their career plans, including reducing working hours (77.96%), retiring early (26.54%) and changing their career away from dentistry (18.15%). The regression model showed that older adults (OR = 1.62; 95% CI: 1.16, 2.26), general practitioners (OR = 1.21; 95% CI: 1.02, 1.44), private practice owners (OR = 2.33; 95% CI: 1.94, 2.79), private practice associates (OR = 2.20; 95% CI: 1.84, 2.63), and those with 'very probable' risk perception (OR = 4.29; 95% CI: 1.35, 13.60) had a significantly greater chance of the pandemic having an impact on their future career plans. CONCLUSIONS: The pandemic has had a great impact on dentists' career plans. Dentists who are most fearful of the risk of contagion, those who are older and those who have their private practice are thinking about reducing working hours, retiring early or changing their career.

Impact of the COVID-19 pandemic on the timing of dental care in Peruvian children.

BACKGROUND: Due to the high transmissibility of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), governments adopted preventive measures, such as social distancing and obligatory social immobilization, which negatively affected access to health services, including oral health services. Similarly, dental care restraint arose in this context, with the aim of reducing the possibility of cross-infection caused by aerosols, which notably restricted dental care activity. OBJECTIVES: The aim of the study was to determine the impact of the COVID-19 pandemic on the timing of dental care in Peruvian children. MATERIAL AND METHODS: A cross-sectional study with a population of 42,115 respondents for 2019 and 20,510 for 2020 was conducted. The participants were children aged 0-11 years. The records of those who responded to the question on the time since their last dental care were considered, extracting a total of 22,166 (69.03%) subjects for 2019 and 9,945 (30.97%) subjects for 2020. The dependent variable consisted of the time since the last dental care measured in years; the variables of health, geographic and sociodemographic characteristics were grouped within 3 dimensions. Descriptive bivariate and multivariate analyses were applied by means of multiple linear regression in order to analyze the variables. RESULTS: The time since the last dental care during 2019 was 5.25 ±4.30 years, and it increased to 6.64 ±4.90 years in 2020. Within the multivariate analysis, the dimensions and their variables were ordered hierarchically for 2019 and 2020 separately, and as a whole. Each model was not significant when observed independently (p > 0.05); however, when evaluated as a whole, validity was observed only in model 1 of the year (p = 0.018), with R2 = 2.90, a constant equal to 3.852, the non-standardized regression coefficient (ß) of 1.653, and a 95% confidence interval (CI) of 0.289-3.018. CONCLUSIONS: The 2020 COVID-19 pandemic year had a negative impact on the timing of dental care in Peruvian children, increasing it by 1.39 years as compared to 2019.

The Effect of Periodontal Treatment on Clinical and Biological Indicators, Quality of Life, and Oral Health in Rheumatoid Arthritis Patients: A Quasi-Experimental Study.

Non-surgical periodontal therapy (NSPT) has been shown to have systemic effects. It has been suggested that, similar to rheumatoid arthritis (RA), periodontitis (PD) has an impact on general health, in terms of psychological, physical, and social aspects. This study determines the effect of periodontal treatment in RA activity, health-related quality of life, and oral health self-perception before and after periodontal treatment in RA patients. A quasi-experimental, prospective, non-randomized study was conducted, and 52 patients were included in the study. Periodontal parameters and the instruments disease activity score-28 (DAS-28), SF-36, and OHIP-14 were measured at baseline and at 3 months after NSPT. All differences were statistically assessed. The study protocol was registered in Clinical Trials (NCT04658615). No statistically significant differences were found in the scores of DAS-28 before and after the intervention in the group with PD and reduced periodontium. When the effect of periodontal treatment was analyzed in the group of 29 patients who were followed up, it was found that there were statistically significant differences before and after in variables such as psychological distress, emotional role, and mental health, which indicates an improvement in the scores of these variables. NSPT influenced the health-related quality of life measured with SF-36 and OHIP-14 in patients with RA. In conclusion, NSPT has an effect on self-reported quality of life and health indicators more than the RA activity as measured with DAS-28. However, the clinical effect of periodontal treatment in RA patients provides important data to support periodontal care in patients.

Preventive measures for COVID­19 among dental students and dentists during the mandatory social isolation in Latin America and the Caribbean in 2020.

BACKGROUND: Dentistry is one of the professions that are most exposed to the contagion with coronavirus disease 2019 (COVID­19). However, the prevalence and positivity rates of COVID­19 are low in dentists, indicating that the current measures of infection control may be sufficient to prevent infection in dental settings. OBJECTIVES: The aim of the study was to determine whether the preventive measures for COVID­19 during the mandatory social isolation were followed by dental students and dentists in Latin America and the Caribbean in 2020. MATERIAL AND METHODS: A cross­sectional study was conducted using anonymous virtual surveys in a convenience sample of 2,036 dental students and dentists from 21 Latin American and Caribbean coun­ tries. The variables were the preventive measures for COVID­19 and the sociodemographic characteristics. Descriptive and bivariate analyses were performed. RESULTS: The final sample included 2,036 dental students and dentists. The self­perceived level of know­ ledge about COVID­19 was found to be associated with age, sex, body mass index (BMI), the type of aca­ demic training, having a specialty in the case of professionals, the place of origin, and having met someone with COVID­19 (p < 0.05). The self­perceived level of concern regarding COVID­19 was associated with sex, BMI and having met someone with COVID­19 (p < 0.05). The number of days in the mandatory social isolation was associated with age, the type of academic training, having a specialty, the place of origin, and having met someone with COVID­19 (p < 0.05). The confinement level was associated with age, sex, BMI, the type of academic training, and having met someone with COVID­19 (p < 0.05). Following the preven­ tive measures for COVID­19 was associated with age, the type of academic training, having a specialty, the place of origin, and having met someone with COVID­19 (p < 0.05). The use of face masks, hand washing and social distancing were associated with age, BMI, the type of academic training, the place of origin, and having met someone with COVID­19 (p < 0.05). CONCLUSIONS: Dental students and dentists followed the preventive measures for COVID­19 during the mandatory social isolation period in Latin America and the Caribbean in 2020.

A qualitative study of employment, working and health conditions among Venezuelan migrants in Colombia.

This study aims to explore the perceptions of the Venezuelan immigrant population in Medellín, Colombia, regarding their employment, working and health conditions (physical, mental and psychosocial). A qualitative study was conducted (focused ethnography perspective). Semi-structured interviews were carried out with 31 Venezuelans and 12 key informants from different social organisations that work with the immigrant population. A narrative content analysis was carried out (Atlas.Ti 8.0 software). The migratory process for Venezuelans is caused for political, economical and social aspects in Venezuela and Colombia is offered as the first destination for labour establishing. Access to the labour market is limited to certain occupations, in many cases in the informal economy. Participants referring low salaries, working long hours and reduced social benefits. Occupational risks are evidenced by low experience in the labour market. Some health problems are perceived, and a good part of the interviewed population referred to signs and symptoms related to mental health problems. Barriers to access health and social protection services were found. Finally, future expectations depend on their adaptation to Colombia, the improvement of social conditions in Venezuela or having chances of improving their social and living conditions in another country. A high labour and social vulnerability were found in Venezuelan participants that impact on physical and mental health. Political and strategies from a public health perspective are required and the implementation of systems for monitoring and evaluating the labour and health situation in the working immigrant population.

Impact of mandatory social isolation measures due to the COVID-19 pandemic on the subjective well-being of Latin American and Caribbean dentists.

BACKGROUND: With the spread of the COVID-19 virus, containment measures such as home confinement were implemented, generating stress, anxiety, depression and aggravation of pre-existing diseases in the population, including dentists, who have also been affected due to the risk involved in practicing their profession. Objective: To determine the impact of mandatory social isolation measures on the subjective well-being of Latin American and Caribbean dentists during the community quarantine due to the COVID-19 pandemic in 2020. MATERIAL AND METHODS: A Cross-sectional study in a sample of 1195 dentists from 21 countries in Latin America and the Caribbean. The main outcome was Subjective Well-Being, evaluated through the World Health Organization Well-Being Index (WHO-5). In addition, sociodemographic characteristics, variables related to the community quarantine due to the COVID-19 pandemic and health variables were considered. A descriptive, bivariate and multivariate (multiple linear regression) analysis was performed to observe the behavior of the variables. RESULTS: A multiple linear regression analysis was performed, where all the variables included within dimensions, were distributed in a single model, observing an R2% of 9.000 (p<0.001), where the R2% change was significant (p<0.001) and a constant of 44.190; likewise, within this model, the variable follow-up of preventive measures against COVID-19 reported an unstandardized regression coefficient (b) of 2. 316 (95%CI:1.133-3.499;p<0.001), the self-perceived level of concern against COVID-19 obtained a (b) of -5.470 (95%CI:-7.509--3.430; p<0.001), the biological sex variable manifested a (b) of -5.417 (95%CI: - 1.157-1.910; p<0.001); finally, the level of economic income during compulsory social isolation presented a (b)=5.354 (CI95%:3.461- 7.247; p<0.001). CONCLUSIONS: An association was found between subjective well-being and variables related to the social impact of the COVID-19 pandemic, such as following preventive measures, concern about the pandemic and economic factors (decrease in income level), in addition to biologic sex. Follow-up strategies are required for these dental professionals, considering that social isolation measures have continued in many of the countries.

Peruvian Children's Access to Oral Health Information during the COVID- 19 Pandemic.

Aim: The aim of this study was to determine the impact of COVID-19 pandemic on access to oral health information of Peruvian children. Materials and Methods: The Demographic and Family Health Survey generates annually a national database of Peruvian children between 0 and 11 years old, which is collected through direct interviews applied in the homes of residents of the country. A cross-sectional study was applied with this information collected during 2019 and 2020, with a final sample of 39 124 subjects, 15 974 from the year 2019 (62.03%) and 7088 from the year 2020 (55.54%). The dependent variable was access to oral health information and the independent variable was year; in addition, there were considered sociodemographic and geographical covariates. Finally, there were executed descriptive, bivariate, and multivariate analyses. Results: Access to oral health information was 59.85% (n = 23 062). For the bivariate analysis, the dependent variable showed association with year, natural region, sex, altitude, health insurance coverage, area, place of residence and wealth index. During multivariate analysis, year manifested a negative association with access to oral health information (aPR: 0.89; 95%CI: 0.85-0.92; P < 0.001), adjusted for co-variables that previously manifested association. Conclusion: Access to oral health information for Peruvian children had a negative impact during 2020, in which COVID-19 pandemic occurred.
