Effectiveness of the ICCMS caries management system for children: a 3-year multicentre randomised controlled trial.

OBJECTIVE: This 3-year multicentre randomised controlled trial compared, in 6-7-year-old Colombian children, the effectiveness of the ICCMS (International Caries Classification and Management System) with a conventional caries-management system (CCMS) in terms of individual caries-risk, caries lesions, and secondarily, oral-health-related knowledge/attitudes/practices, and number of appointments. MATERIAL AND METHODS: With ethical approval, 240 6-7-year olds from six Colombian clinics were recruited. Trained examiners conducted the following baseline/follow-up assessments: Caries risk (Cariogram-ICCMS); caries severity/activity staging (ICDAS-merged combined radiographic/visual); sealants/fillings/missing teeth, and oral-health-related knowledge, attitudes and practices. Children received their randomly allocated (ICCMS/CCMS) care from dental practitioners. Outcomes: caries-risk control (children); caries-progression control (tooth surfaces); oral-health-related knowledge/attitudes/practices improvement (parents/children), and appointments' number (children). Descriptive and non-parametric/parametric bivariate analyses were performed. RESULTS: Three-year-follow-up: n = 187 (77.9%; ICCMS: n = 92; CCMS: n = 95) disclosed a baseline-to-3-year overall high-caries-risk children decrease (ICCMS: 60.9-0%, p < .001; CCMS: 54.7-5.3%, p < .001) (p > .05). ICCMS versus CCMS showed: fewer tooth-surface caries progression (6.2% vs 7.1%, p = .010) and fewer active-caries lesions (49.8% vs. 59.1%, p < .05); higher proportion of children with ≥2/day fluoride-toothpaste tooth-brushing practice (p < .05); similar mean number of appointments (10.9 ± 5.9 vs. 10.0 ± 3.8, p = .15). CONCLUSION: Both caries-management systems showed similar effectiveness in caries-risk control, with ICCMS more effectively controlling tooth-surface caries progression and improving toothbrushing practices.

Influence of the Presence of Alveolar Mucosa at Implants: A Histological Study in Humans.

OBJECTIVE: To evaluate the influence of the presence or absence of keratinized mucosa on hard and soft tissues around implants. MATERIAL AND METHODS: Sixteen volunteers with edentulous regions in the distal aspect of the mandible participated in the study. In each patient, 2 solid titanium screw-shaped devices, 3.5 mm in diameter and 5 mm long, were installed. The incision of the mucosa was performed in such a way to allow that, after the suture of the flaps, only the alveolar mucosa surround the test sites and the keratinized mucosa surround the control implants. After 3 months of healing, biopsies were retrieved and ground sections were prepared for histological analysis. RESULTS: Eighteen biopsies from 9 patients were collected for analysis. Both buccal bone resorption and most coronal level of osseointegration were higher at the test sites compared with the control sites, the difference between the 2 sites being 0.2 and 0.5 mm, respectively. The difference in the coronal level of osseointegration between the test and control sites was statistically significant. Mineralized bone-to-implant contact was 70.6% ± 10.9% at the test sites and 71.5% ± 9.2% at the control sites. CONCLUSIONS: The presence of alveolar mucosa at implants resulted in a more apical position of the coronal level of osseointegration in respect of the implant margin compared with the presence of keratinized mucosa.

Knowledge about emergency dental trauma management among school teachers in Colombia: A baseline study to develop an education strategy.

BACKGROUND/AIM: Dental trauma in school populations has a high frequency and school teachers are often close to the place where such injuries occur. However, many studies have confirmed the lack of knowledge as to how to act in these cases. The aim of this study was to determine the knowledge in regard to dental trauma of school teachers in Colombia. MATERIALS AND METHODS: A multicentre, descriptive cross-sectional study was performed in 251 schools using a stratified randomized sampling. A structured hard copy survey was personally delivered to 2390 school teachers in the selected schools. The survey contained questions related to work experience, teaching level and demographic data, as well as questions related to their knowledge of and attitude towards emergency dental trauma management. RESULTS: The response rate was 96%. Most of the school teachers (95%) had never received training related to dental trauma, although 35% had witnessed at least 1 case. Of 2296 school teachers surveyed, only 5.8% would have replanted an avulsed tooth. An association was found between work experience and appropriate management of an avulsed tooth. No significant differences were found in regard to school location (city), school type (private/public), gender and school teachers' education level. CONCLUSIONS: The knowledge of school teachers in Colombia about emergency dental trauma management is inadequate. The findings strongly suggest a need for an education strategy with the involvement of the government, dentistry schools and private organizations.

Psychometric Properties of the Family Adaptability and Cohesion Evaluation Scale III in Latin American University Dental Students.

OBJECTIVE: The Family Adaptability and Cohesion Evaluation Scale III (FACES III) is a self-report instrument that enables the assessment of the dimensions of adaptability and cohesion within a family, establishing whether or not that family is functional and classifying it according to categories within those dimensions. The objective of this research was to determine the psychometric properties of this instrument using a sample of dental students from 5 Latin American countries. MATERIALS AND METHODS: The FACES III was administered to a sample of 2888 university dental students from Colombia (35.3%), Chile (34.6%), the Dominican Republic (19%), Argentina (6%), and El Salvador (5.1%). Confirmatory factor analysis was used to examine the factorial structure of the scale, comparing 3 models proposed in the Latin American literature, establishing a multigroup analysis to examine invariance among countries. RESULTS: The results revealed a structure composed of 2 dimensions: cohesion and adaptability. These dimensions showed adequate structure and internal consistency. The invariance of the measurement model in the participating countries was confirmed. CONCLUSION: In general, this study offers evidence of the adequacy of the psychometric properties of FACES III in Colombian, Chilean, Dominican, Argentine, and Salvadoran dental students.

Impact of a virtual learning environment on the conscious prescription of antibiotics among Colombian dentists.

Appropriate antibiotic prescription contributes to reducing bacterial resistance; therefore, it is critical to provide training regarding this challenge. The objective of this study was to develop a virtual learning environment for antibiotic prescription and to determine its impact on dentists' awareness, attitudes, and intention to practice. First, the learning content on multimedia resources was developed and distributed into three challenges that participants had to overcome. Then, a quasi-experimental study was performed in which the virtual learning environment was implemented on dentists from seven Colombian cities. The median of correct answers and the levels of awareness, attitudes, and intention to practice were compared before, immediately after, and 6-months post-intervention. Wilcoxon signed-rank and McNemar's tests were used to determine the differences. A total of 206 participants who finished the virtual learning environment activities exhibited a favorable and statistically significant impact on the median of correct answers of awareness (p < 0.001), attitudes (p < 0.001), and intention to practice (p = 0.042). A significant increase occurred in the number of participants with a high level of awareness (p < 0.001) and a non-significant increase in participants with high levels of attitudes (p = 0.230) and intention to practice (p = 0.286). At 6 months, the positive effect on the median of correct answers on awareness and intention to practice persisted (p < 0.001); however, this was not evident for attitudes (p = 0.105). Moreover, there was a significant decrease in the number of participants who showed low levels of awareness (p = 0.019) and a slight increase in those with high levels of the same component (p = 0.161). The use of a virtual learning environment designed for dentists contributed to a rapid improvement in awareness and intention to practice antibiotic prescription; however, their attitudes and information retention need reinforcement.

Prescribing antibiotics by dentists in Colombia: Toward a conscientious prescription.

OBJECTIVES: Inappropriate prescription of antibiotics contributes to antibiotic resistance. Therefore, the objective of this study was to determine the awareness, attitudes, and intention to practice of dentists prescribing antibiotics in Colombia in order to design a virtual learning environment on this subject. METHODS: In a descriptive study across seven cities, 700 dentists from different Colombian cities were requested to complete a validated questionnaire containing five sections: general information, awareness on antibiotic effectiveness and antibiotic resistance, attitudes regarding prescription decision, intention to practice concerning clinical cases, and complementary information. The level of awareness, attitudes, and intention to practice was determined and Chi-square test was used to determine the existence of significant differences among cities. RESULTS: The majority of dentists showed a medium level regarding the number of correct answers on awareness (62.4 percent) and attitudes (88.7 percent) and a high level on intention to practice (91.7 percent). Common errors within the awareness section included the meaning of the term "antibiotic resistance" (35 percent) and most dentists were not convinced that such resistance could be derived from prescription of antibiotics (51.2 percent). In the attitudes section, only 45 percent declared that they prescribe antibiotics based mainly on symptoms, and the intention to practice section showed a significant percentage of unnecessary prescription (51 percent for pacemaker users) or absence of prescription (53.9 percent for ventricular septal defect) in antibiotic prophylaxis for infectious endocarditis (IE). CONCLUSION: The dentists interviewed should be trained and made aware of antibiotic resistance, microbiological and clinical foundations, and current antibiotic prophylaxis guidelines.

Common Mental Disorders and Associated Factors in Dental Students From Cartagena, Colombia. / Trastornos mentales comunes y factores asociados en estudiantes de Odontología en Cartagena, Colombia.

INTRODUCTION: Psychological morbidity assessments are of interest since mental health is part of a person's overall health and early detection promotes emotional well-being. AIM: To determine the association between common mental disorders and related factors in dental students from Cartagena, Colombia. METHODS: We conducted a cross-sectional study in 858 dental students from Cartagena, Colombia; who answered a structured anonymous self-report questionnaire to assess the presence of common mental disorders (CMD) (General Health Questionnaire-12), problematic alcohol consumption (CAGE), sociodemographic and other related variables. Data were analyzed using descriptive statistics and bivariate analysis was conducted later using χ2 tests. The strength of association was obtained with prevalence ratios (PR) and 95% confidence intervals (95%CI). Finally adjusted PRs, and 95%CIs were obtained using a log-binomial regression model. Statistical analysis was performed using Stata v.13.2 for Windows (Stata Corp.; TX, USA). RESULTS: The average age was 20.8±3.01 years of age, and more than half were females. CMD overall prevalence was 30.3% (95%CI, 27.3-33.5). The regression model suggested as associated factors: sex (PR, 1.54; 95%CI, 1.21-1.96), recent economic changes (PR, 1.70; 95%CI, 1.37-2.12), family conflicts [PR, 2.29; 95%CI, 1.89-2.77), abandonment (PR, 1.58; 95%CI, 1.23-2.03), history of abuse (PR, 2.05; 95%CI, 1.27-3.31), and problematic alcohol consumption (PR, 1.35; 95%CI, 1.02-1.78). CONCLUSIONS: CMD prevalence was high. Being female, family conflicts, history of abuse and problematic alcohol consumption are considered as risk factors for CMD development and should be carefully assessed to predict emotional well-being.

Bacterial profile of the supragingival dental biofilm in children with deciduous and early mixed dentition using next generation sequencing (HOMINGS) technique. / Perfil bacteriano del biofilm dental supragingival en niños con dentición temporal y mixta temprana utilizando la técnica de secuenciación de próxima generación (HOMINGS).

OBJECTIVE: Tdescribe the bacterial profile of the supragingival biofilm of children with temporary dentition (CTD) and early mixed dentition (CEMD), with the next-generation sequencing (HOMINGS) technique. METHOD: A comparative descriptive study was carried out with 30 systemically healthy children aged between 5 and 7 years old from public schools in Cartagena-Colombia. All participants were caries-free applying the criteria of the International Caries Detection and Assessment System (ICDAS II) and had no caries experience according to the Decayed, Missing and Filled Teeth (DMFT) index. Supragingival biofilm samples were collected. Bacterial DNA was extracted and used for analysis using HOMINGS (Human Oral Microbe Identification using Next-Generation Sequencing) based on the sequencing of the V3-V4 region of the 16S rRNA gene using the Illumina MiSeq platform (V3-V4 primers). RESULTS: A total of 360 species-specific and 65 genus-specific probes were identified. The bacterial genus most predominant in CTD were Streptococcus, Actinomyces, Veillonella and Fusobacterium (29.2% of all bacterial DNA present), while in CEMD the most predominant were Streptococcus, Leptotrichia, TM7 and Porphyromonas (24.5% of all bacterial DNA present). The bacterial species with the highest relative abundance in the oral biofilm microbiome from CTD were Streptococcus sanguinis, Rothia aeria, Gemella haemolysans, while in CEMD they were S. sanguinis, Leptotrichia spp. HOT-417 and Leptotrichia spp. HOT-498. The Shannon diversity index was 2.77 (SD=0.26) for CTD and 3.01 (SD=0.39) for CEMD (P=0.06). CONCLUSIONS: The analysis of the bacterial profile of the supragingival dental biofilm in children with DMFT, by means of HOMINGS showed low microbiological diversity both in presence and in relative abundance in terms of genus as well as bacterial species.

Objetivo. evaluar la evolución de la empatía y sus dimensiones en dos períodos anuales diferentes y determinar las fortalezas y las deficiencias observadas en la empatía y en sus dimensiones. Material y Métodos. estudio no experimental, descriptivo y transversal. La población la conforman estudiantes colombianos de odontología. La muestra se conformó de dos cohortes: n=326 estudiantes, 100% de la población (cohorte 2016) y n=207 estudiantes, 87,34 % de la población (cohorte 2022). La empatía fue medida por el instrumento JES-HPS. Se aplicó un análisis factorial confirmatorio, fiabilidad e invarianza. Las comparaciones de empatía entre las cohortes se realizaron mediante un análisis de la varianza factorial. Resultados. se cumplió el modelo teórico de tres dimensiones de la empatía en ambas cohortes estudiadas. Los niveles de confiabilidad fueron aceptables. No se encontraron diferencias estadísticas relevantes entre las cohortes y se observa una declinación en el segundo y quinto curso de la empatía y de las dimensiones en general. Conclusiones. los valores de la empatía y sus dimensiones se han mantenido sin cambios en el tiempo y la empatía clasifico como "nivel medio" Como consecuencia de lo anterior, los niveles medios de la empatía podrían asociase a un déficit en la capacidad de entender la subjetividad del pensamiento del paciente y, esta situación, complica una actitud empática normal.

Objective: evaluate empathy and its dimensions in two different annual periods and determine the strengths and weaknesses observed in empathy and its dimensions. Material and methods: non-experimental, descriptive, cross-sectional study. The population was made up of Colombian dental students. The sample consisted of two cohorts: n=326 students, 100% of the population (cohort 2016} and n=207 students, 87,34% of the population (cohort 2022}. Empathy was measured by the JES-HPS instrument. A confirmatory factor analysis, reliability and invariance was applied. Comparisons of empathy between cohorts were performed by factorial analysis of variance. Results: the three-dimensional theoretical model was met in both cohorts studied. Reliability levels were acceptable. No relevant statistical differences were found between the cohorts and a decline is observed in the second and fifth grades of empathy and dimensions in general. Conclusions: the values of empathy and its dimensions have remained unchanged over time and empathy is classified as "medium level" As a consequence of the above, medium levels of empathy could be associated with a deficit in the ability to understand the subjectivity of thought. of the patient and, this situation, complicates a normal empathic attitude.

[Validity and internal consistency of the Maslach Burnout Inventory in Dental Students from Cartagena, Colombia]. / Validez y consistencia interna del Inventario Maslach para burnout en estudiantes de Odontología de Cartagena, Colombia.

OBJECTIVE: To determine the internal consistency and content validity of the Maslach Burnout Inventory-Student Survey (MBI-SS) in dental students from Cartagena, Colombia. MATERIALS AND METHODS: Scale validation study in 886 dental students from Cartagena, Colombia. Factor structure was determined through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Internal consistency was measured using the Cronbach's alpha coefficient. Analyses were performed using the Stata v.13.2 for Windows (Statacorp., USA) and Mplus v.7.31 for Windows (Muthén & Muthén, USA) software. RESULTS: Internal consistency was α=.806. The factor structure showed three that accounted for the 56.6% of the variance. CFA revealed: χ2=926.036; df=85; RMSEA=.106 (90%CI, .100-.112); CFI=.947; TLI=.934. CONCLUSIONS: The MBI showed an adequate internal consistency and a factor structure being consistent with the original proposed structure with a poor fit, which does not reflect adequate content validity in this sample.

Applications of teledentistry in dental practice: a systematic review / Aplicaciones de la teleodontología en la práctica odontológica: revisión sistemática

Abstract Introduction: access to dental services in rural and remote areas is a problem still to be solved; for this purpose, a new alternative known as teledentistry has emerged. Through the application of information and communications technologies (ICTs), teledentistry promotes prevention, diagnosis, and treatment. This study aimed to determine the impact of teledentistry applications on clinical practice in different specialties based on the current evidence in the literature. Methods: two reviewers conducted a literature search in PubMed, EMBASE, EBSCO, ScienceDirect and LILACS databases until August 2019, to identify studies published in English, Spanish and Portuguese. Studies containing interventions applied to teledentistry, published in the last six years and available in full text were included. Bias risk was assessed through validated criteria according to each study type. Results: the search strategy retrieved 1028 articles, 24 of which were selected for evaluation. Twenty-three articles were cross-sectional studies and only one study was quasi-experimental. Seventeen studies (70.8%) considered teledentistry as an alternative to diagnosing and treating oral diseases in rural areas and health centers through mobile devices and clinical photographs. Most studies had moderate to high bias risk. Conclusion: while there is evidence on the use of teledentistry in the various fields of dentistry, it is important to keep in mind that since this is a novel tool that seeks to support access to health services in remote areas, the obtained results are preliminary, and further research with quality publications is necessary to evaluate the effectiveness of this tool.

Resumen Introducción: el acceso a los servicios odontológicos en zonas rurales y remotas es una problemática que aún no está resuelta, por lo que se ha introducido la teleodontología, a través de la aplicación de tecnologías de la información y la comunicación (TICs) por medio de la prevención, diagnóstico y tratamiento. El objetivo del presente estudio consistió en determinar el impacto de las aplicaciones de la teleodontología desde las diferentes especialidades a partir de la evidencia. Métodos: dos revisores realizaron una búsqueda en las bases de datos PubMed, EMBASE, EBSCO, ScienceDirect y LILACS para identificar estudios publicados en inglés, español y portugués. Se incluyeron estudios que contenían intervenciones en teleodontología, publicados en los últimos seis años y en texto completo. La calidad de los artículos se evaluó teniendo en cuenta el diseño del estudio. Resultados: se identificaron 1028 artículos, y se incluyeron 24 artículos para su evaluación. Veintitrés de estos artículos eran estudios transversales y un solo estudio fue de intervención. Diecisiete estudios (70,8%) presentaron la teleodontología como una alternativa para diagnósticos y tratamientos de enfermedades bucales en zonas rurales mediante dispositivos móviles, consultas y fotografías. La mayoría de los estudios presentaban un riesgo de sesgo de moderado a alto. Conclusión: pese a que existe evidencia sobre el uso de la teleodontología en los diferentes campos de la odontología, es importante tener en cuenta que, dado que esta es una herramienta novedosa que busca apoyar el acceso a los servicios de salud en zonas remotas, se hace necesario realizar una nueva búsqueda de evidencia con mejor calidad en la publicación.

Trastornos mentales comunes y factores asociados en estudiantes de Odontología en Cartagena, Colombia / Common Mental Disorders and Associated Factors in Dental Students From Cartagena, Colombia

RESUMEN Introducción: La valoración de morbilidad psicológica resulta de interés porque la salud mental hace parte de la salud integral de un individuo, y la detección precoz de casos propende al bienestar emocional. Objetivo: Estimar la asociación entre trastornos mentales comunes y factores relacionados en estudiantes de Odontología de Cartagena, Colombia. Métodos: Estudio de corte transversal en 858 estudiantes de Odontología de Cartagena, Colombia, que respondieron a un cuestionario estructurado anónimo autoaplicado para evaluar la presencia de TMC (Cuestionario General de Salud-12), consumo problemático de alcohol (CAGE), variables sociodemográficas y otras relacionadas. Se realizó estadística descriptiva y análisis bivariable con pruebas de la x2. La fuerza de asociación se computó con razones de prevalencia (RP) e intervalos de confianza del 95% (IC95%). Con regresión log-binomial, se obtuvieron RP e IC95% ajustados. El análisis se realizó empleando Stata v.13.2 para Windows (Stata Corp.; College Station, Texas, Estados Unidos). Resultados: El promedio de edad fue 20,8 ± 3,01 arios y más de la mitad eran mujeres. La prevalencia de TMC fue del 30,3% (IC95%, 27,3-33,5). El modelo de regresión indicó como factores asociados: sexo (RP, 1,54; IC95%, 1,21-1,96), cambios económicos recientes (RP, 1,70; IC95%, 1,37-2,12), conflictos familiares (RP, 2,29; IC95%, 1,89-2,77)], abandono (RP, 1,58; IC95%, 1,23-2,03), historia de abuso (RP, 2,05; IC95%, 1,27-3,31) y consumo problemático de alcohol (RP, 1,35; IC95%, 1,02-1,78). Conclusiones: La prevalencia de TMC fue alta. Ser mujer y tener conflictos familiares, historia de abuso y consumo problemático de alcohol son factores de riesgo de TMC y deben ser cuidadosamente evaluados para la predicción del bienestar emocional.

Conclusions: CMD prevalence was high. Being female, family conflicts, history of abuse and problematic alcohol consumption are considered as risk factors for CMD development and should be carefully assessed to predict emotional well-being.

Extracurricular factors influence perceived stress in a large cohort of Colombian dental students.

The aim of this study was to investigate the association of extracurricular factors including socioeconomic status and career choice with perceived stress in dental school in a large cohort of Colombian dental students. Participants in the study were 5,700 students enrolled in seventeen Colombian dental schools. The study employed a Spanish adaptation of the Dental Environment Stressors (DES30-Sp) questionnaire and recorded an array of demographic, socioeconomic, career choice, and dental studies-related information. Data analyses relied on descriptive, bivariate, and multivariate methods based on multi-level mixed-effects linear regression and post hoc estimation of predictive margins. "Fear of failing a course or year" emerged as the highest ranked item. Male students consistently reported less perceived stress than females, and stress scores were higher among seniors. Independent of gender, age, and study year, having dentistry as one's first career choice, relying on financial support, and belonging to higher socioeconomic strata were associated with lower stress levels. Academic environment interventions aimed to improve students' educational well-being will need to account for the individual heterogeneity among them. These data from a robust cohort of predoctoral dental students underscore the importance of considering students' educational experiences in a broader social and economic context.

Niveles de citocinas (IL1 β, IL 6 y TNF-α) en estudiantes con estrés académico / Levels of cytokines (IL1 β, IL 6 and TNF-α) in students with academic stress

RESUMEN Objetivo: Establecer la posible relación entre el estrés académico, los cambios en los niveles de citocinas (lL-1β, IL-6) y el factor de necrosis tumoral alfa (TNF-α) en estudiantes de odontología. Métodos: Estudio descriptivo de corte transversal, en el que se evaluó el nivel de estrés académico en estudiantes universitarios y se establecieron los niveles de lL-1β, IL-6 y TNF-α en dos grupos. Uno bajo situación de estrés en una prueba académica, y en otro de regreso del periodo vacacional o momento de no estrés. Resultados: Hicieron parte del estudio 65 participantes. Al evaluar los resultados globales de estrés se encontró un promedio de 1,86 ±0,37 en el momento de no estrés y de 2,61 ± 0,38 en el momento de estrés, encontrándose diferencias estadísticas (p < 0,05). Al comparar los valores de las citocinas se encontraron diferencias estadísticas (p < 0,05) en la LL-1Β, en el momento de estrés y no estrés (p < 0,05). Conclusiones: Las pruebas académicas son uno de los factores estresores que pueden influir sobre las citosinas del sistema inmune, ya que sus valores variaron cuando los pacientes se encontraron bajo situaciones de estrés académico.

ABSTRACT Objective: The present study examined the relationship between academic stress, the cytosines (lL-1β, IL-6) and tumor necrosis factor alpha (TNF-α) changes in a group of dental students. Materials and Methods: Descriptive cross-sectional study, in which the academic stress level was evaluated in university students and the levels of l-1β, IL-6 and TNF-α were established in two groups, one under stress (in an academic test), and in another (back from the holiday period or moment of no-stress). Results: A total of 65 participants were included. The overall results of stress 1.86 ± 0.37 was found at the time of no stress and 2.61 ± 0.38 at the time of stress (p <0.05). Compared to summer vacation, during examinations individuals reported significantly more perceived stress (P < 0.0059), there was higher gene expression of IL-1 (P < 0.01) and IL-6 (P < 0.05) during the period of stress vs. non-stress. Conclusion: Academic exams are one of the stressors that can influence the cytosines of the immune system, since their values varied when patients were under situations of academic stress.

Bone healing of dental alveoli in smokers with platelet-rich plasma obtained using single or double centrifugation

Introduction: the habit of smoking alters the bone healing process, a problem to consider in oral surgery. objective: to evaluate the bone healing of dental alveoli with PRP obtained using single or double centrifugation in smokers. methodology: extraction of mandibular third molars was performed in a study population divided into smoking group (A), which had PRP applied with the protocol using a single centrifugation step (P1C) in the alveolus of tooth 38 and the protocol of double centrifugation (P2C) in alveolus of tooth 48; a smoking group(B), to whom no PRP was applied; and a non-smokers group (C) to whom PRP was applied obtained using P1C and P2C protocol. radiographic examination was performed at 8, 30 and 60 days post procedure. results: thirty patients met the criteria, 57 percent were female. when evaluating bone healing between the group of smokers and non-smokers, statistically significant differences were observed in the non-smoking group at 30 and 60 days, showing better results with the P2C protocol (p<0.005). statistically significant differences were found at 30 and 60 days (p<0.005), both with the P1C and P2C when comparing bone healing of group A and B. conclusions: bone healing in the alveoli of mandibular third molars that which PRP applied was higher in non-smoking patients, compared with the group of smokers. bone healing was better in patients smokers to whom PRP was applied than those without PRP treatment. regarding the method of obtaining PRP, bone healing was better when a double centrifugation protocol (P2C) was applied.

Impacto de salud oral sobre calidad de vida en adultos jóvenes de clínicas odontológicas universitarias / Oral health impact on life quality in young adults at dental university clinics

El objetivo de este estudio es asociar estado de salud oral y calidad de vida en adultos de clínicas odontológicas universitarias de Cartagena, Colombia. Material y Métodos: Estudio analítico, en 400 adultos jóvenes y maduros (20 a 59 años), que asistieron a las clínicas odontológicas de la Universidad de Cartagena y Corporación Universitaria Rafael Núñez, distribuidos equitativamente; se aplicó un instrumento validado para indagar variables sociodemográficas, el General Oral Health Assesment Index (GOHAI) para evaluar impacto calidad de vida relacionada con la salud oral (CVRSB) y examen oral para evaluar número de dientes, presencia de caries dental, placa bacteriana, restos radiculares, cálculo dental y obturaciones. Se analizaron datos a través de frecuencia y proporciones, significancia de relaciones entre variables (c2), estimación del riesgo (OR) y modelo de regresión logística con un intervalo de confianza 95 %. Resultados. 66,7 % de los participantes eran mujeres y se hallaban en adultez madura (54,7 %) edad promedio 44,6 años (DE=13,7). El 33,2 % presentó un impacto negativo de CVRSB (IC 95 %). Se hallaron asociaciones entre bajo nivel de escolaridad (OR=2,4; IC 95 %= 1,6-3,8; p=0,000), ausencia de servicios de salud (OR=1,9; IC 95 %= 1,2-2,8; p=0,002), presencia de menos de 19 dientes (OR=3,6; IC 95 %= 2,3-5,8; p=0,000), restos radiculares (OR=6,5; IC 95 %= 4,1-10; p=0,000) y cálculos (OR=5,3; IC 95 %= 3,3-8,4; p=0,000;) con el impacto negativo de CVRSB. En el modelo multivariado las variables que mejor explican el impacto negativo fueron: ausencia de servicios de salud, contar con menos de 19 dientes, presencia de restos radiculares y cálculos (p<0,05). Conclusión. Adultos jóvenes y maduros presentan un impacto negativo de CVRSB al contar con menos de 19 dientes, presencia de restos radiculares y cálculos dentales y ausencia de servicios de salud.

The aim of this study is to associate oral health status and quality of life in adults treated at university dental clinics in Cartagena, Colombia second semester 2013. Cross-sectional analytical study, in 400 young and mature adults (20-59 years) attending dental clinics University and the University Corporation Cartagena Rafael Nunez and distributed equally between the two institutions; a validated instrument was applied to investigate for sociodemographic variables and the General Oral Health Assessment Index (GOHAI) evaluating the impact of oral health on quality of life (CVRSB); oral exam was performed to evaluate the number of teeth, presence of dental caries and plaque, root fragments, dental calculus and seals. Data were analyzed by frequency and proportion, taking confidence intervals of 95 %, significance of relationships between variables by means of chi-square, risk estimation through OR, and logistic regression model with a confidence level of 95 %. 66.7 % of participants were women and were at the stage of mature adulthood with 54.7 %, with an average age of 44.6 years (SD= 13.7). 60.2 % (95 % CI 55-65) had a low impact of oral health on quality of life, followed by a high impact with 33.2 %. We found associations between low levels of schooling (p=0.000; OR=2.4; IC 95 %= 1.6-3.8), social security (p=0.0.02; OR=1.9; IC 95 %= 1.2-2.8), presence of less than 19 teeth (p=0.000; OR=3.6; IC 95%= 2.3-5.8), root fragments (p=0.000; OR=6.5; IC 95 %= 4.1-10), dental calculus (p=0.000; OR=5.3; IC 95 %= 3.3-8.4) with the negative impact of the CVRSB. In the multivariate model variables that best explain the negative impact of CVSB they were: lack of social security, have fewer than 19 teeth, presence of root fragments and stones (p <0.05). Young and mature adults have a negative impact on CVRSB especially when they have less than 19 teeth, presence of root fragments and dental calculus or when they have no social security arises.

Validity and internal consistency of the Maslach Burnout Inventory in dental students from Cartagena, Colombia / Validez y consistencia interna del Inventario Maslach para burnout en estudiantes de Odontología de Cartagena, Colombia

Abstract Objective: To determine the internal consistency and content validity of the Maslach Burnout Inventory-Student Survey (MBI-SS) in dental students from Cartagena, Colombia. Materials and methods: Scale validation study in 886 dental students from Cartagena, Colombia. Factor structure was determined through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Internal consistency was measured using the Cronbach's alpha coefficient. Analyses were performed using the Stata v.13.2 for Windows (Statacorp., USA) and Mplus v.7.31 for Windows (Muthén & Muthén, USA) software. Results: Internal consistency was α = 0.806. The factor structure showed three that accounted for the 56.6% of the variance. CFA revealed: x 2 = 926.036; df=85; RMSEA = 0.106 (90% CI, 0.100-0.112); CFI = 0.947; TLI = 0.934. Conclusions: The MBI showed an adequate internal consistency and a factor structure being consistent with the original proposed structure with a poor fit, which does not reflect adequate content validity in this sample.

Deformación de las hojas de bisturí al incidir tejido gingival de mandíbulas de cerdo. Estudio ex vivo / Deformation of scalpel blades after incision of gingival tissue in pig mandibles. An ex vivo study

RESUMEN: Introducción: La reología es la ciencia que estudia la deformación de los objetos sometidos a fuerzas externas. Se quiso relacionar esta ciencia con el bisturí, el cual es una herramienta de corte de importancia terapéutica. Objetivo: Describir y comparar la deformación de la superficie cortante de las hojas de bisturí de Bard Parker número 15 de las marcas comerciales Elite® y Paramount®, realizando de uno a cuatro incisiones en encía de cerdos ex vivo. Material y métodos: Estudio de tipo descriptivo comparativo. Se utilizaron mandíbulas de cerdos de uso comercial. Se efectuaron cortes con 20 hojas de bisturí por cada marca comercial. Se utilizó un texturómetro con fuerzas para realizar los cortes, con velocidad regulada, posición constante. Se empleó un estereomicroscopio para fotografiar y comparar la superficie de los escalpelos antes y después de ser utilizados. Se empleó el software ImageJ, para medir el área deformada de las hojas en fotos. Resultados: El esfuerzo en promedio al corte de ambas marcas fue de 49.1 Newtons (N), este esfuerzo no difiere estadísticamente en cada marca en particular, Elite® reportó un esfuerzo general a los cortes de 48.1 N [27.2-179.7], mientras que Paramount® mostró 49.1 N [0.0-60.3] (p = 0.776). Se evaluó la deformación de las hojas de bisturí. Para Elite® se deformaron el 75% de las hojas; para la marca Paramount® fue del 90%. Conclusión: El esfuerzo al corte realizado por las hojas del bisturí aumenta con cada incisión que se realiza influyendo esto directamente con la deformación física de la hoja.

ABSTRACT: Introduction: Rheology is the science that studies deformation of objects when submitted to external forces. This science was associated to the scalpel blade, which is a cutting tool of therapeutic importance. Objective: To describe and compare deformation of the cutting surface of Bard Parker No. 15 scalpel blades (Elite ® and Paramount ® brands), performing one to four cuts in ex vivo pig gums. Material and methods: Comparative-descriptive study. Commercial use pig mandibles were used. Cuts with 20 scalpel blades per brand were performed. A texture analyzer with force to perform these cuts was used, keeping regulated speed and constant position. A stereo-microscope was used to photograph and compare the surface of the scalpel blades before and after being used. ImageJ software was used to measure deformed areas of the scalpel blades in pictures. Results: Average cutting effort from both brands was 49.1 Newton (N), this effort did not statistically differ in each particular brand, Elite ® reported an overall cutting effort of 48.1 N [27.2-179.7], meanwhile Paramount ® showed 49.1 N [0.060.3] (p = 0.776). The deformations of the scalpel blades were evaluated. For Elite ®, 75% of the scalpel blades suffered some kind of deformation; for Paramount ®, 90% did. Conclusion: The cutting effort performed by the scalpel blades increases with each incision performed, which influenced directly the physical deformation of each blade.
