An Umbrella Review of the Effectiveness of Temporary Anchorage Devices and the Factors That Contribute to Their Success or Failure.

OBJECTIVES: New methodological approaches, such as the umbrella review, constitute an important pathway for synthesizing the scientific evidence provided from studies with a high level of evidence. This study aims to summarize the results on the effectiveness of temporary anchorage devices (TADs) and the factors that contribute to their success or failure during orthodontic treatment in patients of different age groups and to identify the gaps in knowledge based on analysis of the scientific literature. METHODS: An umbrella review of systematic reviews and meta-analyses was performed. A quality evaluation and a descriptive analysis of the included studies were conducted. The study protocol was registered at the International Prospective Register of Systematic Reviews (PROSPERO: CRD42018094463). RESULTS: Seventeen systematic reviews and meta-analyses were considered (10 descriptive and 7 with meta-analysis; 12 of high quality and 5 of moderate quality). Variability was observed in the type of intervention and the type of system (TADs). Most of the studies reported high success rates (≥90%), and just one systematic review indicated a low rate of success (≤56%) for the mini-screws. All the studies discussed several factors related to the success of the TADs. These factors were classified as device-related factors, patient-related factors, procedure-related factors, and orthodontic treatment-related factors. Conceptual and methodological gaps were observed when considering the data analysis, the terminology used, and the orthodontic protocols. CONCLUSIONS: The results should be analysed cautiously because of several research gaps related to the methodological quality and the high heterogeneity of the original studies and because of the necessity to add several clinical and sociodemographic variables to enrich the data analysis.

An Umbrella Review Exploring the Effect of Periodontal Treatment in Pregnant Women on the Frequency of Adverse Obstetric Outcomes.

OBJECTIVE: In the recent years, efforts have been made to reduce epidemiologic indicators of periodontal disease in pregnant women. This umbrella review aims to analyze the systematic reviews/meta-analyses investigating the effect of periodontal therapy in pregnant women on the frequency of obstetric complications (low birth weight, preterm delivery, and preeclampsia) and to identify the gaps in the scientific literature. METHODS: A systematic review of systematic reviews with and without meta-analysis of intervention studies was conducted. Quality evaluation and qualitative analysis of the reviews were performed. RESULTS: A total of 223 articles were obtained, and 18 of them were included in the analysis, 13 articles included meta-analysis, where 11 were of high quality and 7 of medium quality according to the Assessing the Methodological Quality of Systematic Reviews (AMSTAR) guide. These systematic reviews/meta-analyses included a total of 19 studies (17 randomized clinical trials). Descriptive systematic reviews showed that periodontal therapy has positive effects on reducing the frequency of adverse pregnancy outcomes. In systematic reviews with meta-analysis, overall effect estimators were not significant, although a reduction in the incidence of obstetric complications was observed. Subgroup analysis resulted in significant effects, depending on sociodemographic conditions. CONCLUSIONS: Differential findings are not enough to demonstrate that there is a significant reduction in the frequency of adverse pregnancy outcomes in pregnant women receiving periodontal therapy. Possible explanations are related to factors such as the type of studies analyzed, indicator of obstetric complication considered, and specific variables included in the analysis. Many systematic reviews did not address publication bias and did identify gaps in knowledge that require further clarification.

Gaps in Knowledge About the Association Between Maternal Periodontitis and Adverse Obstetric Outcomes: An Umbrella Review.

OBJECTIVES: Scientific literature has established that the periodontal condition during pregnancy could be associated with obstetric/neonatal morbidity, and these effects have an important relationship with problems during childhood and cardiovascular disease in adulthood. This umbrella review aimed to summarize the results about the association between maternal periodontitis and obstetric complications (low birth weight, preterm delivery, and preeclampsia) and identify the gaps in the scientific literature. METHODS: An umbrella review of systematic reviews with or without meta-analysis was performed. Quality evaluation and descriptive analysis of the characteristics of the included studies were conducted. RESULTS: Nineteen systematic reviews/meta-analyses were considered. In total, the systematic reviews included 99 observational studies. Most of the reviews established an association between maternal periodontitis and a higher risk of low birth weight, preterm delivery, and preeclampsia. The magnitude and statistical significance of this relationship are influenced by the context in which the studies have been conducted. Gaps were identified in the definition/evaluation of periodontal disease, criteria of gestational age for study purposes, and potential confounders, among others. CONCLUSIONS: Although scientific literature has established an association among the analyzed pathologies, conceptual and methodological gaps were identified, and they should be considered as integral components when this association is investigated.

A qualitative exploration of the impact of the economic recession in Spain on working, living and health conditions: reflections based on immigrant workers' experiences.

BACKGROUND: This study aimed to analyse how immigrant workers in Spain experienced changes in their working and employment conditions brought about Spain's economic recession and the impact of these changes on their living conditions and health status. METHOD: We conducted a grounded theory study. Data were obtained through six focus group discussions with immigrant workers (n = 44) from Colombia, Ecuador and Morocco, and two individual interviews with key informants from Romania living in Spain, selected by theoretical sample. RESULTS: Three categories related to the crisis emerged--previous labour experiences, employment consequences and individual consequences--that show how immigrant workers in Spain (i) understand the change in employment and working conditions conditioned by their experiences in the period prior to the crisis, and (ii) experienced the deterioration in their quality of life and health as consequences of the worsening of employment and working conditions during times of economic recession. CONCLUSION: The negative impact of the financial crisis on immigrant workers may increase their social vulnerability, potentially leading to the failure of their migratory project and a return to their home countries. Policy makers should take measures to minimize the negative impact of economic crisis on the occupational health of migrant workers in order to strengthen social protection and promote health and well-being.

Ethnicity and Health in Colombia: What Do Self-Perceived Health Indicators Tell Us?

OBJECTIVE: To compare self-perceived health indicators between ethnic groups in Colombia. METHODS: Cross-sectional study with data from the 2007 National Public Health Survey (ENSP-2007). Data from 57,617 people ≥18 years were used. Variables included: belonging to an ethnic group (exposure); self-rated health; mental health problems, injuries for accidents/violence (outcomes); sex, age, education level and occupation (explicative/control). A descriptive study was carried out of the explicative variables, and the prevalence of the outcomes was calculated according to ethnicity, education level and occupation. The association between the exposure variable and the outcomes was estimated by means of adjusted odds ratios (OR) with 95% CI using logistic regression. Analyses were conducted separately for men and women. RESULTS: The prevalence of outcomes was higher in people reporting to belong to an ethnic group and differences were found by sex, ethnic groups and health outcomes. Women from the Palenquero group were more likely to report poor self-rated health (aOR 7.04; 95%CI 2.50-19.88) and injuries from accidents/violence (aOR 7.99; 95%CI 2.89-22.07). Indigenous men were more likely to report mental health problems (aOR 1.75; 95%CI 1.41-2.17). Gradients according to ethnicity, education, occupation and sex were found. CONCLUSIONS: Minority ethnic groups are vulnerable to reporting poor health outcomes. Political actions are required to diminish health inequalities in these groups.

Is health a right for all? An umbrella review of the barriers to health care access faced by migrants.

OBJECTIVE: To synthesise the scientific evidence concerning barriers to health care access faced by migrants. We sought to critically analyse this evidence with a view to guiding policies. DESIGN: A systematic review methodology was used to identify systematic and scoping reviews which quantitatively or qualitatively analysed data from primary studies. The main variables analysed were structural and contextual barriers (health system organisation) as well as individual (patients and providers). The quality of evidence from the systematic reviews was critically appraised. From 2674 reviews, 79 were retained for further scrutiny, and finally 9 met the inclusion criteria. RESULTS: The structural barriers identified were the lack of health insurance and the high cost of drugs (non-universal health system) and organisational aspects of health system (social insurance system and national health system). The individual barriers were linguistic and cultural. None of the reviews provided a quality appraisal of the studies. CONCLUSIONS: Barriers to health care for migrants range from entitlement in non-universal health systems to accessibility in universal ones, and determinants of access to the respective health services should be analysed within the corresponding national context. Generate social and institutional changes that eliminate barriers to access to health services is essential to ensure health for all.

Economic crisis, immigrant women and changing availability of intimate partner violence services: a qualitative study of professionals' perceptions in Spain.

INTRODUCTION: Since 2008, Spain has been in the throes of an economic crisis. This recession particularly affects the living conditions of vulnerable populations, and has also led to a reversal in social policies and a reduction in resources. In this context, the aim of this study was to explore intimate partner violence (IPV) service providers' perceptions of the impact of the current economic crisis on these resources in Spain and on their capacity to respond to immigrant women's needs experiencing IPV. METHODS: A qualitative study was performed based on 43 semi-structured in-depth interviews to social workers, psychologists, intercultural mediators, judges, lawyers, police officers and health professionals from different services dealing with IPV (both, public and NGO's) and cities in Spain (Barcelona, Madrid, Valencia and Alicante) in 2011. Transcripts were imported into qualitative analysis software (Atlas.ti), and analysed using qualitative content analysis. RESULTS: We identified four categories related to the perceived impact of the current economic crisis: a) "Immigrant women have it harder now", b) "IPV and immigration resources are the first in line for cuts", c) " Fewer staff means a less effective service" and d) "Equality and IPV policies are no longer a government priority". A cross-cutting theme emerged from these categories: immigrant women are triply affected; by IPV, by the crisis, and by structural violence. CONCLUSION: The professionals interviewed felt that present resources in Spain are insufficient to meet the needs of immigrant women, and that the situation might worsen in the future.

Social and immigration factors in intimate partner violence among Ecuadorians, Moroccans and Romanians living in Spain.

BACKGROUND: Intimate partner violence (IPV) against women occurs in all countries, all cultures and at every level of society; however, some populations may be at greater risk than others. The aim of this study was to explore IPV prevalence among Ecuadorian, Moroccan and Romanian immigrant women living in Spain and its possible association with their personal, family, social support and immigration status characteristics. METHODS: Cross-sectional study of 1607 adult immigrant women residing in Barcelona, Madrid and Valencia (2011). Prevalence rates and adjusted odds ratios (AORs) were calculated, with current IPV being the outcome. Different women's personal (demographic), family, social support and immigration status characteristics were considered as explicative and control variables. All analyses were separated by women's country of origin. RESULTS: Current IPV prevalence was 15.57% in Ecuadorians, 10.91% in Moroccans and 8.58% in Romanians. Some common IPV factors were found, such as being separated and/or divorced. In Romanians, IPV was also associated with lack of social support [AOR 5.96 (1.39-25.62)] and low religious involvement [AOR 2.17 (1.06-4.43)]. The likelihood of current IPV was lower among women without children or other dependents in this subgroup [AOR 0.29 (0.093-0.92)]. CONCLUSION: The IPV prevalence rates obtained for Moroccan, Romanian and Ecuadorian women residing in Spain were similar. Whereas the likelihood of IPV appeared to be relatively evenly distributed among Moroccan and Ecuadorian women, it was higher among Romanian women in socially vulnerable situations related to family responsibilities and the lack of support networks. The importance of intervention in the process of separation and divorce was common to all women.

Understanding sickness presenteeism through the experience of immigrant workers in a context of economic crisis.

BACKGROUND: Previous economic recessions show that immigrant workers may experience longer periods of unemployment, a situation that may lead employees to presenteeism, the act of working in spite of a health problem. This study explored perceptions about the factors that lead to presenteeism in immigrant workers considering the context of economic crisis. METHODS: Six focus group discussions were held (February 2012), with men and women from Colombia, Ecuador, and Morocco (n=44) living in Spain and selected by theoretical sample. A qualitative content analysis was performed. RESULTS: Four categories were identified as factors that influence the occurrence of presenteeism in a context of economic crisis: poor employment conditions, fear of unemployment, employer/employee relationship, and difficulties in finding temporary replacement workers. Furthermore, musculoskeletal, respiratory, and mental problems were related to presenteeism. CONCLUSIONS: It is important to develop strategies to protect workers from negative working conditions that are associated with deterioration of health.

Social determinants of health in post-treatment cancer survivors: Scoping review.

PURPOSE: To identify, analyze and describe the available scientific evidence about the influence of social determinants of health on cancer survivors. METHODS: A scoping review was outlined according to the steps described by the Joanna Brigs Institute Reviewer's Manual: selection of studies, data mapping, and results grouping, synthesis and report, was conducted. PubMed, CINAHL, Scopus and LILACS databases were searched from 2011 to 2023. RESULTS: Out of a total of 1783 papers initially screened, only 19 studies met the inclusion criteria for the scoping review, focusing on the primary social determinants impacting the health of cancer survivors. These studies were categorized into six main themes: a) employment (challenges in work reintegration and work-place difficulties); b) variations among different ethnic groups; c) disparities based on sex; d) barriers and facilitators in accessing health and social security services; e) the role of support networks and social environments; and f) socioeconomic lever (influence of income and socioeconomic status). CONCLUSIONS: Understanding the impact of social determinants on the post-treatment quality of life for cancer survivors is crucial. Comprehensive survivorship care should address not just medical needs but also holistic aspects like social support, education, overall well-being, and improvements in physical and social environments. This multifaceted approach ensures the well-rounded support needed for optimal survivorship outcomes.

Occlusal Plane, Mandibular Position and Dentoalveolar Changes during the Orthodontic Treatment with the Use of Mini-Screws.

This study aimed to describe the changes produced on the occlusal plane (OP), the mandibular position and the dentoalveolar compensations of patients with distalization of the maxillary/mandibular arch assisted by mini-screws (MS). A descriptive case-series study was performed using the digital lateral cephalograms (DLC) of nine patients who underwent orthodontic treatment and required the use of MS for a complete distalization of the maxillary/mandibular arch. Records were collected at three different times (T1-T2-T3) and digitally analyzed (variables: Skeletal diagnosis; maxillary occlusal plane; position of the maxilla/mandible; and dentoalveolar changes of the distalization arch tracing the longitudinal axis of incisors/molars regarding the palatal/mandibular plane). Findings show that the OP varied from T1-T2-T3 in all cases, indicating its stepping or flattening. ODI, APDI, SNA, SNB, and ANB changed minimally in all cases, without variations in the mandibular position or in the skeletal diagnosis. Dentoalveolar measurements also showed differences between T1-T2-T3. In summary, conventional orthodontic treatment modified the OP during the first phase of treatment. Moreover, the distalization mechanics with MS changed the OP and produced dentoalveolar changes, mainly in the inclination of incisors and molars. Other measures considered in the study did not change substantially.

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.

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.

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.

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.

A metasynthesis of qualitative studies regarding opinions and perceptions about barriers and determinants of health services' accessibility in economic migrants.

BACKGROUND: Access to health services is an important health determinant. New research in health equity is required, especially amongst economic migrants from developing countries. Studies conducted on the use of health services by migrant populations highlight existing gaps in understanding which factors affect access to these services from a qualitative perspective. We aim to describe the views of the migrants regarding barriers and determinants of access to health services in the international literature (1997-2011). METHODS: A systematic review was conducted for Qualitative research papers (English/Spanish) published in 13 electronic databases. A selection of articles that accomplished the inclusion criteria and a quality evaluation of the studies were carried out. The findings of the selected studies were synthesised by means of metasynthesis using different analysis categories according to Andersen's conceptual framework of access and use of health services and by incorporating other emergent categories. RESULTS: We located 3,025 titles, 36 studies achieved the inclusion criteria. After quality evaluation, 28 articles were definitively synthesised. 12 studies (46.2%) were carried out in the U.S and 11 studies (42.3%) dealt with primary care services. The participating population varied depending mainly on type of host country. Barriers were described, such as the lack of communication between health services providers and migrants, due to idiomatic difficulties and cultural differences. Other barriers were linked to the economic system, the health service characteristics and the legislation in each country. This situation has consequences for the lack of health control by migrants and their social vulnerability. CONCLUSIONS: Economic migrants faced individual and structural barriers to the health services in host countries, especially those with undocumented situation and those experimented idiomatic difficulties. Strategies to improve the structures of health systems and social policies are needed.

Factors related to compliance with periodontal disease treatment appointments: A literature review.

Periodontal disease is considered a public health problem due to its high prevalence worldwide. Currently, the treatment of periodontal disease is not always successful due to many aspects, including non-compliance with scheduled appointments by the patient. Several authors over the years have evaluated different factors that could be related to non-compliance with periodontal treatment, so the objective of this narrative review of the literature was to explore and analyze the factors that may be related to compliance with periodontal treatment appointments. The results obtained allowed us to conclude that compliance by the patient will depend on a series of multiple factors, however, such compliance will favor the outcome of the periodontal treatment. Key words:Patient Compliance, Treatment Adherence, Periodontal Diseases, (MeSH).

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.

Regenerative Endodontics Success Factors and their Overall Effectiveness: An Umbrella Review.

Introduction: Regenerative endodontics is a developing field of dentistry and aims to recover the physiological and anatomical functions of the tooth for cases of severe dental caries, pulpal pathologies and dental trauma. Materials and Methods: This umbrella review seeks to discover the scientific evidence on the effectiveness and the factors result in successful regenerative endodontic therapies in teeth with necrotic pulps and with incomplete root development. The study was conducted following the PRISMA Guidelines. There were no restrictions regarding search period. A comprehensive literature search was carried out in EMBASE, LILACS, PubMed, Cochrane, Scopus, and Google Scholar. A quality evaluation was conducted by using AMSTAR-2. A descriptive analysis of the included systematic reviews and meta-analysis were conducted. Results: Thirteen descriptive systematic reviews and 7 meta-analyses were included. Three articles evidenced low methodological quality according to AMSTAR-2 tool. Overall success rates for the endodontic regeneration procedures ranged from 50% to 98% and the survival rates were between 94% and 100%. Pulp regeneration had a high success rate, evidenced by factors such as the resolution of symptoms, healing, increased root length, dentin thickening and recovery of sensitivity. Follow-up varied from 1 to 48 months for the original studies included in the systematic reviews and meta-analyses. Conclusions: Endodontic practice offers the clinician a good treatment option in case of necrotic pulp with immature roots such as the endodontic regeneration, that is supported by high and moderate quality scientific literature.
