Development of a three-dimensional printed model from a digital impression of a real patient for aesthetic dentistry undergraduate teaching.

INTRODUCTION: The acquisition of skills and manual dexterity in aesthetic dentistry in undergraduate teaching requires preclinical practices with simulation that should approximate real clinical situations. OBJECTIVE: We will present a digital procedure for the creation of three-dimensional (3D) resin models adapted to the practices of the Aesthetic Dentistry course. MATERIAL AND METHOD: Stereolithography or Standard Tesellation Language (STL) files of a real patient were previously obtained with a 3-shape intraoral scanner. Using the Exocad computer programme for dental prosthesis design, various modifications were made, such as incisor rotation, surface alterations imitating dysplasias or erosions, the creation of diastemas, or even changes in tooth size. The virtual model was printed in resin for use by students. Once the practices were finished, the students and the teachers evaluated the use of the 3D printed models. RESULTS: The result is the typodont model, in which seven laboratory sessions took place: 1-Restoration of conoid tooth morphology, 2-Cervical abrasion/ erosion restoration, 3-Direct Composite Veneer, 4-Aesthetic correction in a tooth with rotation, 5-Diastem closure, 6-Occlusal abrasions/ erosion, and 7-Maryland bridge. 90.48% of the students evaluated the designed 3D model as the best method for laboratory practice compared to other methods, obtaining a general assessment of 8.3 out of 10. CONCLUSION: The method used has provided a reproducible standard analog model for direct aesthetic dental restoration practice, with a good assessment by students and teachers.

Complications Arising from Dental Trauma Incurred from Falls Involving Geriatric Patients: A Case Report.

Elderly patients have a high incidence of falls that result in facial injuries. Many cases present with dental crown fractures and soft-tissue lacerations. The initial diagnosis is especially important in this type of dental trauma, since an initial error can result in the failure to establish the correct treatment from the very beginning, worsening the prognosis, which, in the worst case, can compromise the teeth affected by the trauma. Case report: We present the case of a patient, a 79-year-old woman, who suffered an accidental fall. The patient was examined by a dentist in the emergency room. She was diagnosed with a simple crown fracture of the right upper central incisor and right upper lateral incisor without any pulpal involvement and with laceration of the lower lip. Months later, she had an episode of inflammation in the lower lip, and she developed edema and pain. An X-ray of the lower lip revealed a radiopaque mass compatible with a fragment of dental tissue due to the inclusion of remnants of the dental tissue resulting from the previous accident fall. Conclusions: The population of geriatric patients is steadily increasing in our society, and a higher frequency of falls has been observed in this age group, affecting the maxillofacial region, with consequent dental trauma on many occasions. Therefore, as professionals, we must pay special attention to the prevention and treatment of this problem, insisting on the importance of routine investigation in the emergency visit for dental trauma, which includes a meticulous examination of the soft tissues accompanied by a radiographic examination, when the inclusion of foreign bodies is suspected.

Determination of cardiovascular risk in Spanish veterinarians using different scaling methods.

Introduction: Cardiovascular diseases are responsible for a significant morbimortality rate around the world. Due to the characteristics of their work, health care professionals, including veterinarians, are more prone to present this type of pathology. Objectives: To determine the level of cardiovascular risk using different scales in a group of veterinarians. Methods: A descriptive and cross-sectional study of 610 Spanish veterinarians was conducted to assess cardiovascular risk scores, including 14 overweight and obesity scales, six fatty liver scales, six cardiovascular risk scales, four atherogenic indices, and three metabolic syndrome scales. Results: The prevalence of obesity among women was 7.95%, and 17.53% among men. Hypertension was present in 15.23% of women and 24.68% of men. Dyslipidemia affected 45% of women and 58.64% of men. The prevalence of metabolic syndrome according to the International Diabetes Federation criteria was slightly over 10% while 10.90% of women and 14.93% of men showed moderate to high values on the Registre Gironí del Cor scale. Conclusions: There is a moderate to high level of cardiovascular risk among veterinarians in this group.

Introdução: As doenças cardiovasculares são responsáveis por uma taxa de morbimortalidade significativa no mundo.

A dislipidemia afetou 45% das mulheres e 58,64% dos homens. A prevalência da síndrome metabólica com critérios da International Diabetes Federation foi ligeiramente superior a 10% enquanto valores moderados ou elevados da escala Registre Gironí del Cor foram encontrados em 10,90% das mulheres e 14,93% dos homens. Conclusões: Neste grupo de veterinários, o nível de risco cardiovascular pode ser considerado de moderado a elevado.

Interpersonal violence education: An analysis of the Spanish oral health school's curricula and future requirements.

INTRODUCTION: Interpersonal violence results in injuries that frequently affect oral, head and neck structures, the treatment of which must be carried out by Oral health practitioners with sufficient training to detect the problem and manage the victim's lesions and need for referral. The objective of this study is to know the academic preparation that Spanish dentistry students receive in learning outcomes related to interpersonal violence during undergraduate academic training. MATERIALS AND METHODS: A survey was conducted through an online form with 9 questions (Survey Monkey platform). The link was sent by email to the deans of the 23 Spanish universities (public and private) offering dentistry degrees. The analysis of the results was carried out using Fisher's test and a chi-squared test. RESULTS: 95.63% of the deans (n = 22) responded. 85.7% of the universities report to carry on training in violence, according with Spanish legislation. Currently 33.3% dedicate less than 5 h to this training, whereas in the future study plans only 19% would dedicate less than 5 h to these learning outcomes. 85.7% of the respondents agree in consider this training as mandatory. The subjects in which learning outcomes on interpersonal violence were reported to be included were: legal and forensic dentistry (78%), psychology (55%), medical ethics (33.3%), paediatric dentistry (39%), surgery (5.5%) and 22% respondents cited other specialties. In future curricula, the competence areas in which such training is proposed to be imparted are: legal and forensic dentistry (80.9%), psychology and medical ethics (57.1%), paediatric dentistry (38.1%), surgery (14.2%) and in 23.8% also in other specialties. Significant differences were found between public and private universities only in the number of hours that would be dedicated to interpersonal violence learning outcomes in the future. CONCLUSIONS: Interpersonal violence encompasses situations of abuse and neglect inflicted to different patients (women, children, elderly) that are perceived both by Oral Health students and practitioners to require a comprehensive training. Most of the respondent deans consider that in the future curricula both the hours and areas that teach interpersonal violence learning outcomes must be increased. To respond to victim's need for help and care, the future requirements for the Oral health workforce education must encompass interprofessional undergraduate as well as postgraduate training in interpersonal violence.

Influence of Educational Level and Healthy Habits on the Prevalence of Diabesity in a Spanish Working Population.

BACKGROUND: Diabesity is a growing problem internationally. Taking into account the importance of physical activity and diet in its prevention and treatment, the objective of this study was to delve into the impact of healthy habits on diabesity. METHODS: A descriptive, cross-sectional study was carried out in 386,924 Spanish adult workers. Obesity was determined according to eleven different formulas. Life habits were also valued; sociodemographic variables; and educational level; as well as analytical and clinical variables such as blood pressure and blood glucose levels. The association between the different variables was performed using the chi-square and the Student's t-tests when the samples were independent. A multivariate analysis was performed using the multinomial logistic regression test by calculating the odds ratio and a 95% confidence interval. The Hosmer-Lemeshow goodness-of-fit test was also performed. RESULTS: The overall prevalence of diabesity ranged between 0.3% (95% CI 0.3-0.4) when obesity was assessed according to the abdominal volume index and 8.3% (95% CI 8.2-8.4) when evaluated according to the CUN-BAE (Clínica Universitaria de Navarra Body Adiposity Estimator) formula. The prevalence of diabesity was also higher in workers with a non-heart-healthy diet and in those who did not exercise regularly. CONCLUSIONS: The most disadvantaged socioeconomic classes are those with the highest prevalence of diabesity. It is important to prioritise prevention in populations and communities with the most unfavourable social and environmental conditions to reduce the burden of diabesity.

Relationship between Atherogenic Dyslipidaemia and Lipid Triad with Different Scales of Overweight and Obesity in 418,343 Spanish Workers.

Obesity induces alterations in lipid biochemistry, evolving toward dyslipidaemia atherogenesis, a critical factor in the development of cardiovascular events. Two relevant forms of lipid abnormalities are atherogenic dyslipidaemia (AD) and lipid triad (LT), which involve alterations in triglyceride levels, HDL-c, and LDL-c. The aim of this study was to assess the linkage of atherogenic AD and LT with different scales of overweight and obesity. We carried out a cross-sectional study including 418,343 Spanish adult workers, recruited from workplace health assessments. Atherogenic dyslipidaemia was defined as triglyceride levels ≥ 150 mg/dL, HDL values < 40 mg/dL in men and <45 mg/dL in women, and normal LDL. Additionally, if LDL levels were >160 mg/dL, LT was considered. Subjects affected by AD and LT in the study exhibited significantly higher mean values than those without AD and LT in all overweight, obesity, and body fat related scales studied. VAI (visceral adiposity index) was the strongest predictor of AD (AUC = 0.934, 95% CI: 0.933 to 0.936) and LT (AUC = 0.926, 95% CI: 0.923 to 0.928). Atherogenic dyslipidaemia and LT positively correlate with different scales of overweight and obesity. Further studies should aim to identify other contributory factors. Our obtained data might be useful in laying the groundwork for future works on AD and LT.

Impact of COVID-19 Lockdown on Non-Alcoholic Fatty Liver Disease and Insulin Resistance in Adults: A before and after Pandemic Lockdown Longitudinal Study.

BACKGROUND: Non-alcoholic fatty liver disease is a chronic disease caused by the accumulation of fat in the liver related to overweight and obesity, insulin resistance, hyperglycemia, and high levels of triglycerides and leads to an increased cardiovascular risk. It is considered a global pandemic, coinciding with the pandemic in 2020 caused by the "coronavirus disease 2019" (COVID-19). Due to COVID-19, the population was placed under lockdown. The aim of our study was to evaluate how these unhealthy lifestyle modifications influenced the appearance of metabolic alterations and the increase in non-alcoholic fatty liver disease. METHODS: A prospective study was carried out on 6236 workers in a Spanish population between March 2019 and March 2021. RESULTS: Differences in the mean values of anthropometric and clinical parameters before and after lockdown were revealed. There was a statistically significant worsening in non-alcoholic fatty liver disease (NAFLD) and in the insulin resistance scales, with increased body weight, BMI, cholesterol levels with higher LDL levels, and glucose and a reduction in HDL levels. CONCLUSIONS: Lockdown caused a worsening of cardiovascular risk factors due to an increase in liver fat estimation scales and an increased risk of presenting with NAFLD and changes in insulin resistance.

Impact of COVID-19 Lockdown on Anthropometric Variables, Blood Pressure, and Glucose and Lipid Profile in Healthy Adults: A before and after Pandemic Lockdown Longitudinal Study.

In December 2019, 27 cases of pneumonia were reported in Wuhan. In 2020, the causative agent was identified as a virus called SARS-CoV-2. The disease was called "coronavirus disease 2019" (COVID-19) and was determined as a Public Health Emergency. The main measures taken to cope with this included a state of lockdown. The aim of this study was to assess how the unhealthy lifestyles that ensued influenced different parameters. A prospective study was carried out on 6236 workers in a Spanish population between March 2019 and March 2021. Anthropometric, clinical, and analytical measurements were performed, revealing differences in the mean values of anthropometric and clinical parameters before and after lockdown due to the pandemic, namely increased body weight (41.1 ± 9.9-43.1 ± 9.9), BMI (25.1 ± 4.7-25.9 ± 4.7), and percentage of body fat (24.5 ± 9.1-26.9 ± 8.8); higher total cholesterol levels, with a statistically significant increase in LDL levels and a reduction in HDL; and worse glucose levels (90.5 ± 16.4-95.4 ± 15.8). Lockdown can be concluded to have had a negative effect on health parameters in both sexes in all age ranges, causing a worsening of cardiovascular risk factors.

Differences in cardiovascular risk levels between cleaning staff and hotel housekeepers.

BACKGROUND AND OBJECTIVE: Cardiovascular diseases are the leading cause of morbidity and mortality worldwide, with a greater incidence in the most disadvantaged social classes. In this study, we aimed to evaluate the level of cardiovascular risk in cleaning workers. METHODS: This was a descriptive, cross-sectional study in 46.632 cleaning workers (40.169 women and 6.463 men). Thirty-one different scales related to cardiovascular risk were studied (14 assessing overweight and obesity, 5 determining the risk of nonalcoholic fatty liver disease, 5 scales of cardiovascular risk, 4 atherogenic indices, and 3 scales of metabolic syndrome, among others). The results obtained were divided between personnel who perform their cleaning tasks in the hotel and catering industry and those in other sectors. RESULTS: The prevalence of obesity and arterial hypertension in cleaning workers was over 20% in both sexes. A similar amount was observed in moderate or high values on the REGICOR (Registre GIroní del COR) scale. More than 15% presented metabolic syndrome according to the NCEP ATPIII (National Cholesterol Education Program-Adult Treatment Program III) criteria, while over 10% of women and 20% of men had a high risk of nonalcoholic fatty liver disease assessed with the fatty liver index. CONCLUSION: Cardiovascular risk is higher, in both sexes, in the group of cleaning workers who work in companies other than hotels.

Dentist´s attitude and criteria in the diagnosis and treatment of caries lesions: Survey about a clinical case.

BACKGROUND: The diagnosis of caries, the stage of the disease and the indication of treatment are among the most controversial issues in dentistry. Studies comparing the diagnosis and treatment indication of different professionals show the lack of a unifying criterion in the diagnosis and treatment plan of the disease. The Objectives of this research is to evaluate the attitude of a group of odontostomatologists to a clinical case with lesions compatible with caries, evaluating whether their criteria and attitude in diagnosis and treatment depend on their academic level, years of professional practice, the application of minimal intervention dentistry criteria and the usual practice in conservative restorative treatments. MATERIAL AND METHODS: A survey was applied to dentists registered at the Illustrious Official College of Dentists of the Balearic Islands. The questionnaire was developed by the researchers from a real clinical case. A descriptive statistical analysis was performed of all the generated data and, to evaluate the association between the survey responses and the variables of interest, the χ^2 of independence test was performed. In addition, tests comparing the corresponding proportions were conducted using Fisher's exact test. RESULTS: Regarding pit and fissure significant differences were found in the diagnosis in 46 in terms of dentists' qualifications and in the treatment between the application of minimal intervention dentistry criteria and the usual practice in conservative restorative treatments. No significant differences were found in the other variables analyzed. As regards caries lesions on proximal surfaces, no significant differences were found in the diagnosis or treatment in any of the variables analyzed. CONCLUSIONS: That there is no change in the professional attitude towards the diagnosis and treatment of caries lesions in this group of professionals, having very interventionist criteria and attitudes in all variables analyzed. Key words:Atraumatic restorative treatment, caries detection, demineralization, non-cavitated caries lesions, radiography.

Use of cbct in the endodontic management of a second mandibular premolar with three roots: Clinical case.

BACKGROUND: Reports and studies on dental anatomy describe variations in the morphology, number and shape of the roots and root canals, with the mandibular premolars being one of the dental groups with special complexity. In the bibliographic review published on the morphology of mandibular second premolars, the presence of three roots being extremely rare, finding differences according to the ethnic group studied. The aim of this case is to describe an unusual case of the anatomy of a mandibular second premolar. MATERIAL AND METHODS: A 59-year-old male patient presented with pain in the right mandibular second premolar. After taking the clinical history and the examination, he was diagnosed with irreversible serous pulpitis. Endodontic emergency treatment was started with the location of two root canals and the suspicion of two roots, according to radiographic examination. After performing CBCT, the presence of a third root was discovered in 45 and the presence of another anatomical variant in the right mandibular first premolar (44). RESULTS: Endodontic treatment was performed in the three canals of 45 (mesio-vestibular, disto-vestibular and lingual). Clinical controls were carried out at 12 and 18 months. CONCLUSIONS: With the limitations of this clinical case, we can conclude that Anatomical knowledge is essential for performing endodontic treatment. The study of the tooth with CBCT is essential in cases where the anatomy of the tooth shows abnormalities in the radiographic study. Key words:CBCT, Endodontic Management, Mandibular premolars, Radiography, Anatomy.

OBJECTIVE: To evaluate different cardiovascular risk scales in construction workers. METHODS: A descriptive, cross-sectional study was carried out in 56,262 Spanish construction workers. Scales of obesity and fatty liver, metabolic syndrome, atherogenic indices, and cardiovascular risk scales, among others, were assessed. RESULTS: In women, 19.6% were obese, 18.2% hypertensive, 12.6% had metabolic syndrome, 12% were at high risk of non-alcoholic fatty liver disease, and 4.3% were at moderate or high risk on the SCORE scale. In men, 20.1% were obese, 30.1% hypertensive, 17.5% had metabolic syndrome, and 27.6% had high or moderate risk on the SCORE scale. CONCLUSIONS: Knowing the cardiovascular risk of a large number of construction workers by means of a large number of scales may be of great interest to occupational health professionals, as it may enable them to establish prevention strategies.

Cardiometabolic risk profile in relation to the practice of healthy habits in a sample of Spanish workers

Insulin resistance is a pathological entity that can lead to alterations in lipid metabolism and can increase cardiovascular risk. Objective. The aim of this study was to assess the influence of different sociodemographic variables such as age, sex and social class and healthy habits such as smoking, physical activity and adherence to the Mediterranean diet on the cardiometabolic profile of Spanish workers. Material and methods. A descriptive, cross-sectional study was carried out in 1457 Spanish workers in an attempt to evaluate the effect of healthy habits (physical exercise determined with the IPAQ questionnaire, Mediterranean diet and tobacco consumption) and sociodemographic variables (age, sex and social class) on the values of different insulin resistance scales. Results. The progressive increase in the level of physical activity and high adherence to the Mediterranean diet achieved an improvement in the mean values and in the prevalence of elevated values in all the insulin resistance scales analyzed in this study. Age over 50 years and belonging to the least favored social classes (social classes II-III) were the variables that increased the risk of presenting insulin resistance. Male sex also increased the risk of presenting insulin resistance. Conclusions. The different healthy habits such as vigorous physical exercise and high adherence to the Mediterranean diet improve the values of the different scales that assess insulin resistance(AU)

La resistencia a la insulina es una entidad patológica que puede provocar alteraciones en el metabolismo de los lípidos y puede aumentar el riesgo cardiovascular. Objetivo. En este trabajo se pretende valorar la influencia de diferentes variables sociodemográficas como la edad, el sexo y la clase social y hábitos saludables como el consumo de tabaco, la actividad física y la adherencia a la dieta mediterránea en el perfil cardiometabólico de trabajadores españoles. Material y métodos. Se realizó un estudio descriptivo y transversal en 1457 trabajadores españoles intentando evaluar el efecto de los hábitos saludables (ejercicio físico determinado con el cuestionario IPAQ, dieta mediterránea y consumo de tabaco) y las variables sociodemográficas (edad, sexo y clase social) sobre los valores de diferentes escalas de resistencia a la insulina. Resultados. El aumento progresivo del nivel de actividad física y la alta adherencia a la dieta mediterránea consiguieron una mejoría en los valores medios y en la prevalencia de los valores elevados en todas las escalas de resistencia a la insulina analizadas en este estudio. La edad por encima de los 50 años y la pertenencia a las clases sociales menos favorecidas (clases sociales II-III) fueron las variables que aumentaron el riesgo de presentar resistencia a la insulina. El sexo masculino también incrementó el riesgo de presentar resistencia a la insulina. Conclusiones. Los diferentes hábitos saludables como el ejercicio físico vigoroso y la alta adherencia a la dieta mediterránea mejoran los valores de las diferentes escalas que valoran resistencia a la insulina(AU)

Determination of crown discoloration and fluorescence induced by different medications used in regenerative endodontic procedures: An ex vivo study.

BACKGROUND: Crown discoloration is an undesirable side effect of the use of triple antibiotic paste (TAP) in regenerative endodontic procedures (REPs). The aim of this ex vivo study was to assess the potential for tooth discoloration and induction of fluorescence associated with the use of TAP containing either doxycycline (DOX) or clindamycin (CLIN), and of calcium hydroxide (Ca(OH)2), by spectrophotometric analysis and confocal laser scanning microscopy (CLSM). MATERIAL AND METHODS: A total of forty single-rooted human teeth extracted by therapeutic indication were used. The root canals were enlarged using the step-back technique up to a K #80 file and were randomly divided into four experimental groups (10 specimens each): i)Ca(OH)2 group, ii)TAP with DOX group, iii) TAP with CLIN group, iv) Control group (no treatment). To quantify the change of color of the different groups of teeth included, the Vita Easyshade advance 4.0 spectrophotometer was used. CLSM was used to determine fluorescence. RESULTS: After 28 days of action inside the root canal, no extreme discoloration was visible, to the naked eye, in any of the teeth included in the study. Under the conditions of this ex vivo study, TAP with DOX induced the highest crown discoloration among the medicaments tested. In contrast, Ca(OH)2 and TAP with CLIN did not induce crown discoloration after 28 days. The TAP with DOX group presented the highest fluorescence measurements. CONCLUSIONS: Considering the discoloration potential and fluorescence changes in TAP with DOX or other tetracyclines, and the cytotoxic effect of TAPs, we recommend the use of Ca(OH)2 for REPs. Key words:Discoloration, doxycycline, clinadamycin, calcium hydroxide, endodontics.

Pruebas de laboratorio COVID-19 y su implicación en el tratamiento dental / COVID-19 laboratory tests and their implication in dental treatment

Desde la identificación del virus SARS-CoV-2 como causante de la enfermedad y pandemia COVID-19, el diagnóstico de los infectados, el control de los grupos de riesgo y la inmunidad de la población han sido los principales objetivos de la comunidad científica. Son imprescindibles las pruebas de laboratorio para diagnosticar a los contagiados, determinar el estado y evolución de la enfermedad en los pacientes con clínica y la inmunidad que ha desarrollado cada grupo social. Dependiendo de los resultados de las distintas pruebas de laboratorio COVID-19, los profesionales sanitarios indican diferentes actuaciones. Los Odontólogos debemos indicar la realización de tratamientos dentales basándonos en los resultados de las pruebas de laboratorio COVID-19 dado el alto riesgo de diseminación y contagio que conllevan nuestros tratamientos.

Since the identification of the SARS-CoV-2 virus as the cause of the disease and the COVID-19 pandemic, the diagnosis of the infected population, the control of risk groups, and the immunity of the population have been the main objectives of the scientific community. Laboratory tests are essential to diagnose infected population, determine the status and evolution of the disease in patients with symptoms, and the immunity that each social group has developed. Depending on the results of the different COVID-19 laboratory tests, healthcare professionals indicate different actions and treatments. Dentists must take into account the results of COVID-19 laboratory tests of their patients as input before to the performance of any dental treatments, given the high risk of spread and contagion that dental treatments entail.

Odontología conservadora mínimamente invasiva o sobretratamiento. ¿Dónde estamos / No disponible

Presentamos un caso clínico en el que una paciente solicita una segunda opinión diagnóstica ante la indicación de caries interproximal en 1.6 con necesidad de reconstrucción dental y protección pulpar en ausencia de signos o/y síntomas clínicos. Tras la anamnesis, la exploración clínica y radiográfica no se detectan lesiones de caries. Se exponen los errores diagnósticos que podemos tener en una mala interpretación de las imágenes radiográficas y los métodos complementarios alternativos para obtener un diagnóstico de certeza, poniendo en énfasis la necesidad de tratamientos conservadores de mínima intervención para evitar sobretratamientos

We present a clinical case in which a patient requested a second diagnostic opinion on the indication of interproximal caries in 1.6 as being in need of dental reconstruction and pulp protection despite the absence of clinical signs or symptoms. After hearing the patient's history no caries or lesions were detected in clinical and radiographic examination. Diagnostic errors that can be made in misinterpretation of the radiographic images and the alternative complementary methods used to obtain diagnostic certainty were exposed, thereby emphasizing the need for conservative treatment of minimal intervention to avoid over-treatment

External Cervical Resorption: A New Oral Manifestation of Systemic Sclerosis.

Systemic sclerosis (SSc) is a complex, chronic, and progressive autoimmune disease. SSc causes bone resorption of mandible and distal phalanges of fingers through a known mechanism, and it has also been pointed out as a possible cause of apical root resorption of teeth, because tooth resorption is regulated by similar mechanisms to those controlling bone resorption. The objective of this article was to report the first case in the literature of external cervical resorption (ECR) as an oral manifestation of SSc. A 66-year-old female patient with a 35-year history of SSc was diagnosed with multiple ECRs through a computerized axial tomography and clinical examination. All known causes of ECR were discarded after a detailed anamnesis and clinical examination. This report details SSc as a possible cause of ECR and discusses the pathogenesis of ECR in relation with SSc. The systemic alterations provoked by SSc can be related to the etiopathogenesis of cervical root resorption. It is extremely relevant that dental care providers be aware that external cervical resorptions could be present in patients suffering from SSc, consciously look for these lesions, treat them early in case they are present, and advise the patient with SSc of the importance of continuous dental controls.

Tratamiento conservador ante una reabsorción externa apical en un paciente medicamente comprometido / Use of glass fiber in the restoration of angle fractures. New clinical technique

Exponemos el caso de un paciente al que se le diagnostica una reabsorción de la raíz distal de la pieza 3,6 en una exploración radiográfica. El paciente había sido sometido a un tratamiento de conductos en dicha pieza hacia 20 años y ha permanecido asintomático. Tras valorar el tipo de reabsorción que presenta, la actividad del proceso y las posibilidades de re-endodoncia y reconstrucción se decide realizar tratamiento conservador (AU)

We report the case of a patient who is diagnosed with a distal root resorption of the 3.6 tooth, a radiographic examination. The patient had undergone a root canal treatment on that tooth 20 years ago and has remained asymptomatic. After assessing the type of apical resorption, the activity of the process and the possibilities of retreatment and coronal reconstruction, a conservative treatment was choosed (AU)
