ABSTRACT
Background: This study aims to compare the cyclic fatigue resistance (CFR) of the Reciproc Blue and WaveOne Gold instruments under a dynamic cyclical fatigue test. Material and Methods: 210 Reciproc Blue "R25" and WaveOne Gold "primary" files were assigned into 7 groups (n =15) for each brand. Groups G: Files were not exposed to NaOCl or sterilization. Groups A and D: files were immersed for 3 minutes in NaOCl 1 and 3 times, respectively. Groups B and E: Files were autoclaved 1 and 3 times, respectively. Groups C and F: files were exposed to both, NaOCl immersion and autoclaving 1 and 3 times, respectively. Subsequently, files underwent a dynamic CFR test. The chemical composition of the files' surface from Group G was analysed by energy-dispersive X-ray spectroscopy (EDS). Cyclic fatigue resistance time was statistically analysed using 1-way and 2-way analyses of variance (ANOVA) and T-test. A p-value ≤0,05 was set to be statistically significant. Results: There was a significantly higher CFR of RB files than WOG in groups A, B, C, D and G (p<0.05). WOG files were superior to RB in group E (p>0.05). There were no statistically significant differences between files in group F (p>0.05). RB files from groups B, C, D, E and F had significantly lower resistance than new ones (Group G) (p<0.05). WaveOne Gold files exposed to 5 % NaOCl immersion in combination with sterilization cycles (Groups C and F) had significantly lower CFR than new ones (p<0.05). Reciproc Blue and WaveOne Gold NiTi alloys differed in atomic wt % of carbon, oxygen, nickel and titanium. Conclusions: The Reciproc Blue files outperformed the WaveOne Gold files in terms of CFR. The Reciproc Blue files were more vulnerable to the cycles of NaOCl immersion or autoclave sterilisation. The combined autoclaving and NaOCl cycles had the most significant impact on the mechanical properties of both files. Key words:Cyclic fatigue, Reciproc blue, Wave one gold, Dynamic test, Simulated channels, Sodium hypochlorite, Sterilization.
ABSTRACT
Although several studies have evaluated the effect of low-level laser therapy (LLLT) on orthodontic movement acceleration, results are still inconsistent. Such inconsistencies may be attributed to the differences in the LLLT application protocols, especially in terms of wavelength ranges. Objective: (i) to assess the clinical effects of LLLT on the acceleration of orthodontic movement and (ii) to establish the most effective LLLT wavelength to accelerate tooth movement during orthodontic treatments. MEDLINE (PubMed), Scopus, ScienceDirect, and LILACS were searched from inception to October 2022. Inclusion criteria: Split-mouth randomised clinical trials (RCTs) on systemically healthy patients reporting the effect of LLLT in accelerating orthodontic movements, specifically retraction of canines. The risk of bias was assessed using RoB-2. A random effect model was applied. Nineteen RCTs met the inclusion criteria for qualitative synthesis, and eighteen RCTs were included in the quantitative synthesis. Seventeen studies were rated as at some concerns of bias and two studies were classified as having a low risk of bias. In general terms, this systematic review and meta-analysis presents a moderate risk of bias. Findings of this systematic review and meta-analysis point to a tendency for faster orthodontic dental movement in the groups receiving LLLT treatment during the first (OR of 0.28 95% CI (0.07 to 0.48)), second (OR of 0.52 95% CI (0.31 to 0.73)), and third (OR of 0.41 95% CI (0.03 to 0.79)) month follow-up. Wavelengths ≤ 810 nm and energy density values ≤ 5.3 J/cm2 were associated with faster orthodontic tooth movement.

Background: The main objective of this systematic review is to evaluate the effectiveness of platelet concentrates -Platelet-rich plasma (PRP) or Fibrin-rich plasma (PRF)- compared with blood clot (BC) as scaffolds for maturogenesis, in patients with immature permanent teeth with or without AP, in terms of the criteria for pulp revascularization success. Material and Methods: We reviewed randomized controlled clinical trials comparing regenerative endodontic therapies (maturogenesis) based on PRP or PRF versus the conventional BC approach, in necrotic teeth with or without apical periodontitis (AP) under clinical and radiographic criteria. We performed a strategic search in MEDLINE (PUBMED), EMBASE, and ISI Web of Science from inception to October 2022. This systematic review of the literature was developed following the Cochrane Collaboration and PRISMA statement recommendations. We used the Cochrane risk of bias tool v2 to assess the included studies' quality. We performed a qualitative synthesis of the evidence. Results: Ten randomized controlled clinical trials were included in this systematic review. Analyses of these studies suggest that maturogenesis is a successful therapy regardless of the method employed. However, further research should be conducted with more suitable research methodologies and more homogenous data for meta-analysis. Conclusions: Results from this systematic review suggest that BC maturogenesis approaches yield similar clinical and radiographic outcomes when compared to Platelet-concentrates based therapies (PRP and PRF). Key words:Maturogenesis, Revascularization, Platelet-rich plasma, Fibrin-rich plasma, blood clot, systematic review.
ABSTRACT
Objectives: This systematic review and meta-analysis aimed to assess the association of cigarette smoking with the prevalence of post-endodontic apical periodontitis in humans. Materials and Methods: We searched through PubMed/Medline, Web of Science, and Scopus from inception to December 2020. Risk of bias was performed by using the Newcastle-Ottawa Scale for cross-sectional, cohort, and case-control studies. We performed the statistical analysis in Review Manager 5.3 (RevMan 5.3). Results: 6 studies met the inclusion criteria for qualitative and quantitative synthesis. Statistical analysis of these studies suggests that there were no differences in the prevalence of post endodontic apical periodontitis (AP) when comparing non-smokers vs smoker subjects regarding patients (odds ratio [OR], 0.68; 95% confidence interval [CI], 0.31-1.49; I2 = 58%) and teeth (OR, 1.71; 95% CI, 0.99-2.93; I2 = 72%). Conclusions: Our findings suggest that there was no association between cigarette smoking and post-endodontic apical periodontitis, as we did not find statistical differences in the prevalence of post-endodontic AP when comparing non-smokers vs smoker subjects. Therefore, smoking should not be considered a risk factor associated with endodontic failure.
ABSTRACT
Objetivo: caracterizar los estilos de vida de estudiantes de grado 11 en los colegios oficiales de la Provincia Sabana Centro, Cundinamarca, a partir de creencias y prácticas en torno a la actividad física, el manejo del tiempo libre, los hábitos alimentarios, el consumo de sustancias psicoactivas y el autocuidado. Métodos: se realizó un estudio cuantitativo, descriptivo transversal en una muestra de 281 estudiantes. Resultados: la población objeto del estudio presenta hábitos y conductas no favorables, especialmente en lo concerniente a prácticas alimentarias, actividad física, manejo del sueño, uso de sustancias psicoactivas y sexualidad. Conclusión: la población escolar adolescente evidencia estilos de vida, actitudes y prácticas poco saludables, principalmente en lo relacionado a actividad física, hábitos alimentarios, manejo del sueño, uso de sustancias psicoactivas y sexualidad. Estos aspectos constituyen factores de riesgo frente al padecimiento de enfermedades crónicas no transmisibles a edades tempranas. Es necesario diseñar programas de fomento y promoción de la salud y prevención de la enfermedad que involucren procesos psicosociales.
Objective: to characterize the lifestyles of 11th grade students in the official schools of the Sabana Centro Province, Cundinamarca, based on beliefs and practices around physical activity, free time management, eating habits, consumption of psychoactive substances and self-care. Methods: a quantitative, descriptive cross-sectional study was carried out in a sample of 281 students. Results: the population object of the study presents unfavorable habits and behaviors, especially regarding eating practices, physical activity, sleep management, use of psychoactive substances and sexuality. Conclusion: the adolescent school population shows unhealthy lifestyles, attitudes and practices, mainly in relation to physical activity, eating habits, sleep management, use of psychoactive substances and sexuality. These aspects constitute risk factors for suffering from chronic non-communicable diseases at an early age. It is necessary to design programs for the promotion and promotion of health and disease prevention that involve psychosocial processes.

OBJECTIVE: The purpose of the present study was to assess the influence of type 2 diabetes mellitus (DM) on the evolution of pulpal and periapical pathology. METHOD AND MATERIALS: Two reviewers independently conducted a systematic search for articles published between 1 January 2001 and 31 December 2018 on MEDLINE/PubMed, ISI Web of Science, and Scopus databases. An additional manual search was also carried out. RESULTS: Ten studies fulfilling the inclusion criteria were included in the review (two longitudinal studies with 1-year follow-up comparing the success of primary root canal treatment between type 2 diabetic patients and non-diabetic patients, and eight cross-sectional studies). Analysis of the ten studies showed that inadequate control of type 2 DM may predispose and influence the inflammatory pulpal and periapical disease evolution. CONCLUSIONS: The present systematic review suggests that there are biologic bases to suggest that type 2 DM may act as a risk factor for developing an endodontic pathology, affecting the course of the disease in terms of susceptibility, prevalence, progression, and tissue healing capacity as a consequence of a disrupted immune response. However, more well-designed clinical investigations carrying out suitable research methodologies are needed to elucidate the influence of type 2 DM on the pulpal and periapical disease evolution.

Abstract Introduction: Leishmaniasis is a reemerging disease that causes more sequelae and disability than any other of its kind in areas where geographical conditions favor the presence of the vector. Objective: To describe the behavior, geographical distribution and initial clinical management of cutaneous leishmaniasis in the department of Boyacá between 2008 and 2015. Materials and methods: Observational, retrospective study on a sample of patients diagnosed with cutaneous leishmaniasis in the department of Boyacá, Colombia, registered in the mandatory epidemiological notification sheets of the Colombian public health surveillance system from 2008 to 2015. Results: 63.6% of patients were men with occupations related to forestry activities and from rural areas. 81% of the reported cases were located in western Boyacá, along the Magdalena River basin, one of the main tributaries of Colombia. Inadequate initial clinical management was observed in 25% of the study sample, which is a risk factor for resistance to pentavalent antimonials. Conclusion: It is necessary to implement follow-up strategies for patients with cutaneous leishmaniasis in order to verify the cure criteria for the disease and propose strategies for its prevention in the identified populations that are at greater risk.

Introduction: Cutaneous leishmaniasis is a public health problem widely recognized in the literature. Colombia has been considered an endemic country for this vector-borne infection. Treatment represents a challenge because of lack of follow-up, high drug toxicity, and the resistance to antileishmanial drugs. Objective: The aim of this study was to describe the epidemiological behavior of cutaneous leishma-niasis in the department of Boyacá, Colombia, between 2012 and 2015. Materials and methods: A retrospective, descriptive and observational study was carried out. The sample was taken from the files of notification of the Colombian epidemiological surveillance system, belonging to patients diagnosed with cutaneous leishmaniasis in the department of Boyacá, Colombia, from 2012 to 2015. Qualitative variables were analyzed by absolute and relative frequencies and the quantitative variables were reported through measures of central tendency. Results: The subjects widely affected were young males from rural areas with forestry jobs or students in those rural areas. The incidence in 2014 was the highest, with 173 cases, followed by 124 in 2013, 2.012 with 102 and, finally, 2015 with 75 cases of cutaneous leishmaniasis. Conclusion: Leishmaniasis is a problem that affects the department of Boyacá, mainly in the western part of the state, where conditions of geographical relief and human development generated the invasion of the niche of the transmitting vector. In addition, poor access to health services makes it difficult to treat and monitor the disease, which is consistent with the world scientific literature

ABSTRACT
Resumen La enfermedad de moyamoya (EMM) es una patología crónica caracterizada por la oclusión progresiva de la vasculatura cerebral y no aterosclerótica, generando un patrón angiográfico conocido como moyamoya, que en japonés hace alusión a la apariencia en "bocanada de humo", trae como consecuencia eventos cerebrovasculares isquémicos o hemorrágicos. Tiene dos picos de presentación, uno entre los 5 y 9 años y otro entre los 45 y 49 años, con un ligero predominio en mujeres, suele ser más frecuente en individuos de origen asiático, y menos en personas de origen hispano. El tratamiento de elección es el procedimiento quirúrgico precoz y su pronóstico no es totalmente predecible. Reporte de caso: mujer de 44 años que ingresó por presentar movimiento tónico-clónicos y requirió IOT, con tomografía axial computarizada cerebral simple que mostró hematoma intraparenquimatoso izquierdo y arteriografía con patrón moyamoya. Se manejó en la unidad de Cuidados Intensivos, donde finalmente falleció.
Summary Moyamoya disease (EMM) is a chronic disease characterized by progressive occlusion of the cerebral vasculature and nonatherosclerotic, generating an angiographic pattern known as moyamoya, which in Japanese refers to the appearance "puff of smoke", results in cerebrovascular ischemic or hemorrhagic events. Presentation has two peaks, one between 5 and 9 years and another between 45 and 49 years, with a slight predominance in women over men, usually more common in individuals of Asian origin, and less in people of Hispanic origin. The treatment of choice is early surgical procedure and prognosis is not entirely predictable. Case report: 44-year-old woman presenting income tonic-clonic movement and required IOT, single computed tomography showed left cerebral intracerebral hematoma and arteriography with Moyamoya pattern. It was handled in Intensive Care Unit, where he eventually died.
