RESUMO
La pandemia por SARS-CoV2 cambió el ritmo de vida habitual y como consecuencia tuvo influencia para el desarrollo de situaciones parafuncionales, como el posible bruxismo, generando una huella en la calidad de vida. Determinar el posible bruxismo en la calidad de vida relacionada con la salud oral (CVRSO) en pacientes que tuvieron y no SARS-Cov2 en Yucatán, México, durante junio-diciembre de 2021. estudio correlacional, descriptivo, transversal, participaron 119 sujetos del estado de Yucatán que presentaron y no SARS-CoV2 a través de la aplicación de forma virtual en la plataforma Google Forms de dos cuestionarios digitalizados: el primero para la medición del posible bruxismo elaborado y adaptado por la Dra. Celia Elena del Perpetuo Socorro Mendiburu-Zavala con base en los autores Ordóñez-Plaza et al. (2016), González-Emsoto et al. (2015) y De La Hoz-Aizpurua & Winocur (2014). Para el estudio de la CVRSO se empleó el OHIP-14 diseñado por Castrejón-Pérez et al. (2010). Utilizando pruebas estadísticas como Ji Cuadra, Kruskal-Wallis y la prueba U de Mann-Whitney para identificar factores de asociación. Resultados: con respecto a la prevalencia del posible bruxismo en sujetos con SARS-CoV2 (n=43) según la edad, los adultos maduros (36 a 59 años) y mayores (de 60 años y más), presentaron mayores porcentajes que los jóvenes (18 a 35 años). Para determinar el efecto del posible bruxismo en la CVRSO en personas que tuvieron y no SARS-CoV2 se utilizó la prueba estadística de Kruskal-Wallis, no se encontraron diferencias estadísticamente significativas entre ninguno de los grupos (c ∑ = 2.87; p = .411). El efecto del posible bruxismo en la CVRSO en personas que tuvieron y no SARS-CoV2 no tiene un efecto estadísticamente significativo. Sin embargo, el posible bruxismo altera la CVRSO y sí hay una fuerte influencia de factores como la edad y contexto cultural.
The SARS-CoV-2 pandemic changed the usual rhythm of life and therefore had an influence for the development of parafunctional situations, such as possible bruxism, generating an imprint on quality of life. To determine possible bruxism in oral health-related quality of life (OHRQoL) in patients who did and did not have SARS- CoV-2 in Yucatan, Mexico, during June-December 2021. Materials and methods: correlational, descriptive, cross- sectional study, 119 subjects from the state of Yucatan who did and did not present SARS-CoV-2 participated through the virtual application in the Google Forms platform of two digitized questionnaires: the first for the measurement of possible bruxism elaborated and adapted by Dr. Celia Elena del Perpetuo Socorro Mendiburu-Zavala based on the authors Ordóñez Plaza et al. (2016), González-Emsoto et al. (2015), and De La Hoz-Aizpurua & Winocur (2014). For the study of the OHRQoL the OHIP-14 designed by Castrejón-Pérez et al. was used. They were used statistical tests such as Ji Cuadra, Kruskal-Wallis and the Mann- Whitney U test to identify factors of association. Results: regarding the prevalence of possible bruxism in subjects with SARS-CoV-2 (n=43) according to age, mature adults (36 to 59 years) and older adults (60 years and older) presented higher percentages than young adults (18 to 35 years). To determine the effect of possible bruxism on OHRQoL in people who did and did not have SARS-CoV-2, the Kruskal- Wallis statistical test was used; no statistically significant differences were found between any of the groups (c∑ = 2.87; p = .411). the effect of possible bruxism on OHRQoL in subjects who did and did not have SARS-CoV-2 did not have a statistically significant effect. However, possible bruxism did alter OHRQoL and there was a strong influence of factors such as age and cultural context.
RESUMO
BACKGROUND: Bovine pericardium (BP) is a scaffold widely used in soft tissues regeneration; however, its calcification in contact with glutaraldehyde, represent an opportunity for its application in hard tissues, such as bone in the oral cavity. OBJECTIVE: To develop and to characterize decellularized and glutaraldehyde-crosslinked bovine pericardium (GC-BP) as a potential scaffold for guided bone regeneration GBR. METHODS: BP samples from healthy animals of the bovine zebu breed were decellularized and crosslinked by digestion with detergents and glutaraldehyde respectively. The resulting cell-free scaffold was physical, chemical, mechanical, and biologically characterized thought hematoxylin and eosin staining, DNA quantification, scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), uniaxial tensile test, cell viability and live and dead assay in cultures of dental pulp stem cells (DPSCs). RESULTS: The decellularization and crosslinking of BP appeared to induce conformational changes of the CLG molecules, which led to lower mechanical properties at the GC-BP scaffold, at the same time that promoted cell adhesion and viability of DPSCs. CONCLUSION: This study suggests that the decellularized and GC-BP is a scaffold with the potential to be used promoting DPSCs recruitment, which has a great impact on the dental area.

RESUMEN: El estrés es una reacción normal en humanos. Cuando se mantiene durante tiempo prolongado, pudiera ocasionar desequilibrios en los sistemas, como en el estomatognático presentándose como una parafunción llamada bruxismo, exteriorizándose como apretamiento, rechinamiento o ambos, trayendo repercusiones orales negativas. Los estudiantes universitarios y deportistas de alto rendimiento están más expuestos al estrés. Correlacionar los niveles de estrés con el bruxismo durante la pandemia en estudiantes y deportistas universitarios que solicitaron el servicio de Unidad de Atención Integral de la Salud (UAIS) en casa de manera virtual de la Universidad Autónoma de Yucatán (UADY), México, enero-abril-2021, estudio observacional, correlacional, analítico, prospectivo, corte transversal. Muestra de 66 estudiantes y deportistas universitarios que solicitaron el servicio de manera virtual durante la pandemia de COVID-19, a los cuales se les aplicó dos instrumentos: la Escala de Estrés Percibido (EPP) de Cohen et al. (1983) y el instrumento para la medición del bruxismo elaborado y adaptado por la Dra. Celia Elena del Perpetuo Socorro Mendiburu-Zavala. Para el análisis se utilizó estadística descriptiva e inferencial. El 83,3 % (n=55) presentó algún nivel de estrés percibido. Con respecto al bruxismo, el 86,4 % (n=57) tuvo presencia. Al correlacionar ambos, se identificó que los hombres son más afectados que las mujeres. Se observa reflejado en el bruxismo de sueño y en no deportistas. Se concluye que sí existe una relación entre el estrés y bruxismo en estudiantes y deportistas.
ABSTRACT: Stress is a normal reaction in humans. When it is maintained for a log time, it could cause imbalances in the systems, such as in the stomatognathic, presenting itself as a parafunction called bruxism, externalizing as a clenching, grinding or both, bringing negative oral repercussions. College students and high-performance athletes are more exposed to stress. The objective was to correlate stress levels with bruxism during the pandemic in university students and athletes who requested the Comprehensive Health Care Unit (UAIS in spanish) service at home virtually from the Autonomous University of Yucatán (UADY in spanish), Mexico, January-April-2021, Observational, correlational, analytical, prospective, cross-sectional study. Sample of 66 university students and athletes who requested the serice virtually during the COVID-19 pandemic, to whom two instruments were applied: the Perceived Stress Scale (PPS) by Cohen et al. (1983) and the instrument for the measurement of bruxism elaborated and adapted by PhD Celia Elena del Perpetuo Socorro Mendiburu-Zavala, presented some leve lof perceived stress, 83.3 % (n=55). Regarding bruxism, 86.4 % (n=57) had presence of it. It was identified that men are more affected tan women. It is observed reflected in sleep bruxism and in non-athletes. It is concluded that there is a relationship between stress and bruxism in students and athletes.

RESUMEN: Una mala calidad del sueño y estrés, pueden ser la génesis de anomalías temporomandibulares que consisten en una familia heterogénea de desórdenes músculoesqueletales que representan la afección de dolor orofacial crónica más común. El objetivo de este trabajo fue relacionar la calidad del sueño, estrés percibido y desórdenes temporomandibulares dolorosos en adultos jóvenes de dos comunidades mexicanas (Puebla y Yucatán). Material y Métodos: estudio de tipo correlacional, analítico, prospectivo, de corte transversal. Se obtuvo consentimiento informado y voluntario por medio de firmas de 552 sujetos adultos jóvenes: 276 de Puebla (P), 53 % (n=147) mujeres, 47 % (n= 129) hombres, con un promedio de 28 años (± 4,5); y 276 sujetos de Yucatán (Y), 58 % (n=161) mujeres, 42 % (n= 115) hombres, con un promedio de 27 años (±4,9). Se les realizó entrevistas con base a tres cuestionarios: Índice de Calidad de Sueño de Pittsburg (ICSP), Escala de Estrés Percibido de Cohen (EEP) e Instrumento de Examinación de Desórdenes Temporomandibulares Doloroso de González (IEDTD). Para el análisis estadístico se utilizó estadística descriptiva (frecuencias y porcentajes), regresión logística y correlación de Pearson. Puebla presenta un porcentaje mayor de individuos con calidad de sueño pobre 83 %, comparado con Yucatán, 56 %. De la misma forma, Puebla muestra un porcentaje mayor de individuos con estrés alto, 82 %, comparado con Yucatán, 74 %. Por otro lado, Puebla presenta un porcentaje mayor de individuos con DTM dolorosos, 33 %, comparado con Yucatán, 11 %. Asimismo, existe una correlación moderada general entre el estrés percibido y la calidad del sueño en mujeres (0,335) y edades de 30 a 35 años (0,383) ambas con una significancia de p <0,001. La calidad de sueño pobre aumenta 4 veces la posibilidad de padecer un DTM doloroso. Vivir en Puebla aumenta hasta 3.1 veces la posibilidad de un DTM doloroso.
ABSTRACT: Por sleep quality and stress may be the génesis of temporomandibular disorders that consist of a heterogeneous family of musculoskeletal disorders that represent the most common chronic orofacial pain condition. The objective of the study was to relate sleep quality, perceived stress, and painful temporomandibular disorders in Young adults from two Mexican communities (Puebla and Yucatán). a correlational, analytical, prospective, cross- sectional study. Informed and voluntary consent was obtained through the signatures of 552 young adult subjects: 276 from Puebla (P), 53 % (n = 147) women, 47 % (n = 129) men, with an average of 28 years (± 4.5); and 276 subjects from Yucatán (Y), 58 % (n = 161) women, 42 % (n = 115) men, with an average age of 27 years (±4.9). Interviews were conducted based on three questionnaires: Pittsburg Sleep Quality Index (ICSP), Cohen's Perceived Stress Scale (EEP) and González's Painful Temporomandibular Disorders Examination Instrument (IEDTD). Descriptive statistics (frequencies and percentages), logistic regression and Pearson's correlation were used for statistical analysis. Puebla has a higher percentage of individuals with por sleep quality, 83 %, compared to Yucatán, 56 %. In the same way, Puebla shows a higher percentage of individuals with high stress, 82 %, compared to Yucatán, 74 %. On the other hand, Puebla has a higher percentage of individuals with painful TMD, 33 %, compared to Yucatán, 11 %. Likewise, there is a general moderate correlation between perceived stress and sleep quality in women (0.335) and ages 30 to 35 years (0.383), both with a significance of p <.001. Poor sleep quality increases the chance of painful TMD by 4 times. Living in Puebla increases the possibility of painful TMD up to 3.1 times.
RESUMO
Dental tissue-derived mesenchymal stem cells (DT-MSCs) are a promising resource for tissue regeneration due to their multilineage potential. Despite accumulating data regarding the biology and differentiation potential of DT-MSCs, few studies have investigated their adipogenic capacity. In this study, we have investigated the mesenchymal features of dental pulp stem cells (DPSCs), as well as the in vitro effects of different adipogenic media on these cells, and compared them to those of periodontal ligament stem cells (PLSCs) and dental follicle stem cells (DFSCs). DFSC, PLSCs, and DPSCs exhibit similar morphology and proliferation capacity, but they differ in their self-renewal ability and expression of stemness markers (e.g OCT4 andc-MYC). Interestingly, DFSCs and PLSCs exhibited more lipid accumulation than DPSCs when induced to adipogenic differentiation. In addition, the mRNA levels of adipogenic markers (PPAR, LPL, and ADIPOQ) were significantly higher in DFSCs and PLSCs than in DPSCs, which could be related to the differences in the adipogenic commitment in those cells. These findings reveal that the adipogenic capacity differ among DT-MSCs, features that might be advantageous to increasing our understanding about the developmental origins and regulation of adipogenic commitment.
RESUMO
The aim of this study was to evaluate the mixture of Calcium Sulfate and Plasma Rich in Growth Factors (CaSO4 + PRGF) as a bone-graft substitute in extracted mandibular third molar (MTM) alveoli during a 4-month period. Bilateral MTM extractions were performed in 10 patients (18-25 years) at the Oral-Surgery-Clinic of the Universidad Autónoma de Yucatán (UADY). A CaSO4 + PRGF mixture was placed in the right alveolus (Experimental Group (EG)) and a natural blood clot in the left (Control Group (CG)). Monthly X-ray controls were performed using a gray scale to measure Bone Regeneration (BR). A non-parametric Sign Test was used to evaluate Radiopacity/Bone Regeneration (Ro/BR) over 4 months, and a Friedman's non-parametric test was used for intra-group analysis over these months. The study was approved by the Centro de Investigaciones Regionales (Dr. Hideyo Noguchi, UADY Bioethics Committee, ID 0026-2015). Using a non-parametric test of the sign, the EG showed significant difference of Ro/BR between groups p = 0.002 (p < 0.05). Significant differences were observed in all quadrants and areas p = 0.002 (p < 0.05) except in area A in month 4 (p = 0.016), which could be explained by its being the closest to native bone. EG CaSO4 + PRGF showed a higher degree of bone regeneration compared to CG.
RESUMO
BACKGROUND: Dental pulp (DP) represents an accessible and valuable source promising of stem cells for clinical application. However, there are some disadvantages associated with the isolation of dental pulp stem cells (DPSCs), which include the size and weight of the pulp tissue needed to yield sufficient cells for culturing in vitro. Therefore, the objective of this study was to compare in vitro histomorphometry of DP from permanent (premolars, third molar), supernumerary and deciduous teeth of patients between 5 and 25 years old with regards to weight, length, width and the cell density in the four regions of the DP in order to obtain quantitative parameters in a tissue that represents a valuable source of stem cells. METHODS: DPs were obtained from 10 central incisors deciduous, 20 permanent teeth (10 premolars, 10 third molars) and 10 supernumeraries (six mesiodents and four inferior premolar shapes). The pulps were carefully removed, and the entire tissue was weighed. The pulp length and the width were measured with a digital Vernier caliper. The cellular density analysis was performed according to the four regions of the DP (coronal, cervical, medial and apical) in histological slides using photography and the ImageJ® program for quantification. RESULTS: The Pearson correlation test revealed that DP weight among different types of teeth is correlated with age in male patients. A significant positive correlation was noted between length and width of the DP with age in both genders. The mean DP weight for supernumerary and third molar teeth was greater than deciduous and premolar teeth. Finally, the histological analysis showed that the coronal and apical portions of DP in supernumerary and premolar teeth have the highest cell density. CONCLUSIONS: The DP of supernumerary teeth has quantitatively the best morphometric parameters and cell density comparable with the quality of DP obtained from deciduous teeth.
RESUMO
Obesity is a rising public health problem that contributes to the development of several metabolic diseases and cancer. Adipocyte precursors outside of adipose depots that expand due to overweight and obesity may have a negative impact on human health. Determining how progenitor cells acquire a preadipocyte commitment and become mature adipocytes remains a significant challenge. Over the past several years, we have learned that the establishment of cellular identity is widely influenced by changes in histone marks, which in turn modulate chromatin structure. In this regard, histone lysine demethylases (KDMs) are now emerging as key players that shape chromatin through their ability to demethylate almost all major histone methylation sites. Recent research has shown that KDMs orchestrate the chromatin landscape, which mediates the activation of adipocyte-specific genes. In addition, KDMs have functions in addition to their enzymatic activity, which are beginning to be revealed, and their dysregulation seems to be related to the development of metabolic disorders. In this review, we highlight the biological functions of KDMs that contribute to the establishment of a permissive or repressive chromatin environment during the mesenchymal stem cell transition into adipocytes. Understanding how KDMs regulate adipogenesis might prompt the development of new strategies for fighting obesity-related diseases.

Computed tomography imaging of the temporomandibular joint was carried out in 22 previously-diagnosed arthritis patients (3 men, 19 women). This descriptive, cross-sectional observational, qualitative study allowed to characterize the type of condylar morphology condition, the space between temporomandibular joint, the erosion of the cortical and osteophytes formation. The joint characteristics found were cortical erosion, osteophytes and decrease of joint space, which reveals, for the first time in the literature, a correlation between arthritis and temporomandibular joint disease.
RESUMO
Introducción: cuando las estructuras dentales permanentes tienen pulpas jóvenes e inmaduras, son más grandes y las paredes del canal radicular muy delgadas. Si estas son afectadas por alguna enfermedad pulpar o periapical, la integridad de la pulpa se ve dañada y consecuentemente el desarrollo radicular. Objetivo: identificar las enfermedades pulpares y periapicales en estructuras dentales permanentes y su grado de desarrollo según la clasificación de Patterson, de pacientes con edades de seis a catorce años. Métodos: estudio observacional descriptivo y transversal. De 357 pequeños que acudieron a la Unidad Universitaria de Inserción Social de la Universidad Autónoma de Yucatán, México, 2013, por afectaciones pulpar o periapical, 56 infantes presentaron estas, en estructuras dentales inmaduras permanentes. Los criterios de inclusión fueron: edad, estructura dentaria, enfermedades pulpares y periapicales, clasificación de Patterson para observar radiográficamente el grado de desarrollo radicular. Se proporcionó a los padres una carta de consentimiento informado, realizándoles un cuestionario con datos demográficos del niño. Al niño, se le preguntó su historia de dolor, se realizaron pruebas, exámenes clínicos y toma radiográfica. Con pruebas Ji-cuadrada se comparó la proporción de pacientes según: 1) estructura dentaria; 2) edad; 3) clasificación de Patterson; 4) enfermedad pulpar y periapical. Resultados: el 57 por ciento fueron niñas y 43 por ciento niños. El 15,69 por ciento de los infantes tuvo enfermedad pulpar y/o periapical en estructuras dentales permanentes presentándose con mayor frecuencia en el estadio 1, 2 y 3 de Patterson. Difirió significativamente (X2= 22,6429; p= 0,0004; g.l.= 5) la estructura dentaria afectada. La proporción de pacientes con enfermedad pulpar o periapical según edad difirió significativamente (X2= 30,75; p< 0,0001; g.l.= 6). La proporción de pacientes con alguna estructura dentaria permanente afectada según la clasificación de Patterson, difirió significativamente (X2= 7,75; p= 0,0208; g.l.= 2). Hubo diferencias estadísticas entre los tipos de enfermedades pulpares (X 2= 7,2; p= 0,0273; g.l.= 2), no difirió significativamente entre los tipos de enfermedades periapicales (X2= 1,4615; p=0,4815; g.l.= 2). Conclusiones: desde muy temprana edad los niños y niñas, están presentando mayor cantidad de enfermedades pulpares que periapicales en estructuras dentales permanentes aún sin terminar su desarrollo radicular, lo que pone en riesgo la conservación de sus dientes en la edad adulta, y afecta severamente el sistema estomatognático con probabilidad de padecer maloclusiones a temprana edad(AU)
Introduction: when permanent dental structures have young, immature pulps, they are bigger and their root canal walls are very thin. If they are affected by some pulp or periapical disease, damage is caused to pulp integrity and consequently to root development as well. Objective: identify pulp and periapical diseases in permanent dental structures of patients aged six to fourteen years, and their degree of development according to Patterson's classification. Methods: a cross-sectional observational descriptive study was conducted. Of the 357 children attending the Social Service University Unit at the Autonomous University of Yucatán, Mexico, in the year 2013, for pulp or periapical diseases, 56 presented them in immature permanent dental structures. The following inclusion criteria were applied: age, dental structure, pulp and periapical diseases, and Patterson's classification, to radiographically observe the degree of root development. Parents provided their informed consent in writing, and answered a questionnaire with personal details of the child. Children were asked about the antecedents of their pain, and underwent tests and clinical and radiographic examination. Chi-square tests were used to sort out the patients according to: 1) dental structure, 2) age, 3) Patterson's classification, 4) pulp and periapical disease. Results: 57 percent of the sample were girls and 43 percent were boys. 15.69 percent had pulp and/or periapical disease in permanent dental structures, with a higher prevalence of Patterson's stages 1, 2 and 3. The dental structure affected varied significantly (X2= 22.6429; p= 0.0004; g.l.= 5). The proportion of patients with pulp or periapical disease varied significantly with age (X2= 30.75; p< 0.0001; g.l.= 6). The proportion of patients with some permanent dental structure affected varied significantly according to Patterson's classification (X2= 7.75; p= 0.0208; g.l.= 2). Significant statistical differences were found between the types of pulp diseases (X2= 7.2; p= 0.0273; g.l.= 2), not between the types of periapical diseases (X2= 1.4615; p=0.4815; g.l.= 2). Conclusions: incidence of pulp diseases is higher than that of periapical diseases in very young children. These affect permanent dental structures with incomplete root development, jeopardizing tooth preservation in adult age and severely affecting the stomatognathic system with a potential for causing malocclusion at an early age(AU)

Fundamento: las emergencias médicas son eventos agudos que requieren de conocimientos suficientes para su atención inmediata. Objetivo: identificar las necesidades de aprendizaje en emergencias médicas de pasantes de la Licenciatura en Cirugía Dental. Métodos: se realizó un estudio descriptivo, en la Facultad de Odontología de la Universidad Autónoma de Yucatán, México, en 2015. Se utilizaron métodos teóricos: análisis-síntesis e inducción-deducción, para fundamentar la investigación. Se aplicó una encuesta en forma de cuestionario estructurada con preguntas cerradas con las variables de conocimiento básico sobre situaciones de emergencias médicas en el consultorio dental, y una prueba binomial. Resultados: se identificaron insuficiencias en los conocimientos acerca de la capacitación para enfrentar emergencias médicas en el consultorio dental, entre ellas: aplicar un medicamento intramuscular, qué vía utilizar para administrar determinados medicamentos y sus dosis, qué hacer en caso de que el paciente tenga alta la presión sistólica y no la diastólica y viceversa, cómo utilizar la mascarilla facial con bolsa de resucitación, así como aplicar la Reanimación Cardiopulmonar. Sin embargo, en las emergencias metabólicas, presentaron altos porcentajes de respuestas positivas. Conclusión: se presenta una alta necesidad de aprendizaje en emergencias médicas en la consulta dental de los pasantes, debido a que su conocimiento está por debajo de los estándares aceptables.
Background: medical emergencies are acute events that require sufficient knowledge for immediate attention. Objective: to identify the learning needs of medical emergency interns of the Bachelor of Dental Surgery. Methods: an descriptive study was carried out at the Faculty of Dentistry at the University of Yucatan, Mexico, in 2015. Theoretical methods were used: analysis-synthesis and induction-deduction, to support research. A survey was applied as structured questionnaire with closed questions with variable basic knowledge about medical emergencies in the dental office, and a binomial test. Results: gaps in knowledge about training were identified to deal with medical emergencies in the dental office, including: applying an intramuscular medication, which route to use to administer certain medications and dosages, what to do if the patient has high systolic and normal diastolic blood pressure and vice versa, how to use the facemask with resuscitation bag and apply Cardiopulmonary Reanimation. However, in metabolic emergencies, they showed high percentages of positive responses. Conclusion: there are high learning needs in medical emergencies in the dental office of interns, because their knowledge is below acceptable standards.

Introducción: la oclusión traumática se define como una alteración en las relaciones oclusales del sistema masticatorio, lo cual podría ser un factor conducente a un proceso inflamatorio en el ligamento periodontal, en la pulpa dental, y en tejidos blandos sensitivos. Objetivo: identificar las afecciones pulpares de origen no infeccioso en órganos dentarios con oclusión traumática en pacientes de un hospital del sector público de Mérida, Yucatán, México. Métodos: se realizó un estudio observacional y analítico, en un hospital del sector público de Mérida, Yucatán, México (2014). La muestra estuvo constituida con un total de 156 órganos dentarios de 82 pacientes, de 20 y más años de edad, que presentaron oclusión traumática en dientes permanentes y que mostraron alguna afección en tejido pulpar de origen no infeccioso, de acuerdo con la clasificación de la Academia Americana de Endodoncia. También se incluyó a los pacientes que presentaban caries, fracturas, fisuras, obturaciones, endodoncia, ortodoncia o trauma dentoalveolar. Se empleó un muestreo No probabilístico, por conveniencia. Se obtuvo el consentimiento informado y voluntario, historia médica y dental, y se realizó la evaluación de los signos y síntomas de dolor, pruebas pulpares (térmicas y eléctricas), palpación y percusión y abordaje diagnóstico con tinción/transiluminación, así como pruebas oclusales con papel de articular y examinación e interpretación de radiografías periapicales. Se utilizó estadística descriptiva. Resultado: hubo ausencia de dolor en 53 por ciento de los 156 órganos dentarios estudiados. Las alteraciones radiográficas se presentaron en 63 por ciento: entre ellas los nódulos pulpares tuvieron el mayor porcentaje (25 por ciento). La pulpitis fue reversible en 37 por ciento (n= 58); la oclusión traumática más frecuente fue la maloclusión (n= 49). En los 156 órganos dentarios estudiados, el signo clínico que mostró mayor frecuencia fue el desgaste en esmalte (n= 56). Conclusiones: las afecciones pulpares de origen no infeccioso se presentaron en alto porcentaje de dientes permanentes de pacientes con oclusión traumática(AU)
Introduction: Occlusal trauma is defined as an alteration in the occlusal relationships of the masticatory system, which may lead to inflammation of the periodontal ligament, the dental pulp and sensitive soft tissues. Objective: Iidentify non-infectious pulpal disorders in dental organs with occlusal trauma of patients from a public hospital in Mérida, Yucatán. Methods: An observational analytical study was conducted at a public hospital in Mérida, Yucatán, Mexico (2014). The study universe was 156 dental organs of 82 patients aged 20 years and over with occlusal trauma in permanent teeth and some degree of non-infectious pulp tissue disorder, based on the classification of the American Academy of Endodontics. Patients were also included who presented caries, fractures, fissures, fillings, endodontic treatment, orthodontic treatment or dentoalveolar trauma. Convenience non-probability sampling was applied. Voluntary informed consent was obtained. Medical and dental records were examined. An evaluation was carried out of pain signs and symptoms. Thermal and electric pulp tests were performed, as well as palpation, percussion and diagnostic staining/transillumination. Occlusal testing was conducted using articulating paper. Periapical radiographs were examined and interpreted. Descriptive statistics were used. Result: There was no pain in 53 percent of the dental organs studied. Radiographic alterations were present in 63 percent; the most common were pulp nodes (25 percent). Pulpitis was reversible in 37 percent (n= 58), and the most frequent occlusal trauma was malocclusion (n= 49). In the 156 teeth studied, the most common clinical sign was enamel wear (n= 56). Conclusions: Non-infectious pulpal disorders were present in a large number of permanent teeth of patients with occlusal trauma(AU)
