ABSTRACT

Abstract Alterations in saliva, temporomandibular joint disorders, dysphagia, Sjogrens syndrome, dental caries, periodontal disease, and tooth loss have been identified in patients with Rheumatoid Arthritis. The aims of this research were 1) to study the association between newly diagnosed rheumatoid arthritis and dental caries and 2) to identify most frequent teeth with caries in study groups. A descriptive pilot study was performed. A total of 620 participants were evaluated, 29 met the selection criteria. The subjects were divided into 2 groups: 13 subjects with newly diagnosed rheumatoid arthritis and 16 subjects without rheumatoid arthritis. Salivary parameters, DMFT index, care index, FS-T index and Treatment Needs Index were evaluated in all participants. The Fishers Exact test and Mann-Whitney U test we used to establish the differences between groups. Low mean in all salivary parameters and a high caries frequency were observed in subjects with newly diagnosed rheumatoid arthritis compared to a control group (p<0.01). The right maxillary second premolar (n=6, 46%, p=0.0100); right mandibular second premolar (n=7,54%, p=0.0462) and left mandibular second molar (n=10,77%, p=0.0001) were the most frequent teeth with caries. Early diagnosis and early treatment of rheumatoid arthritis can improve the prognosis in most of patients. The development of new public health policies and care based on the prevention are necessary to improve the quality of patients lives.


Resumen Alteraciones en la saliva, trastornos de la articulación temporomandibular, disfagia, síndrome de Sjogren, caries dental, enfermedad periodontal y pérdida de dientes son algunas patologías que se han identificado en pacientes con artritis reumatoide. Los objetivos de este estudio fueron (1) Asociar la artritis reumatoide recientemente diagnosticada con la caries dentales e (2) Identificar los dientes más frecuentes con caries en los grupos de estudio. Se realizó un estudio piloto descriptivo. 620 participantes fueron evaluados, 29 sujetos cumplieron con los criterios de selección. Los sujetos se dividieron en 2 grupos: 13 sujetos con artritis reumatoide recién diagnosticados y 16 sujetos sin artritis reumatoide. En todos los participantes se evaluaron parámetros salivales, el índice CPOD, el índice IC, el índice FS-T y el índice INT. La prueba exacta de Fisher y U de Mann-Whitney se utilizaron para establecer diferencias entre grupos. En los resultados se observó un bajo promedio de los parámetros salivales y una alta frecuencia de caries en sujetos con artritis reumatoide recién diagnosticados comparados con un grupo control (p<0.01). El segundo premolar superior derecho (n=6,46%, p=0,0100); el segundo premolar mandibular derecho (n=7,54%, p=0.0462) y el segundo molar mandibular izquierdo (n=10,77%, p=0.0001) fueron los dientes más frecuentes con caries dental. El diagnóstico y el tratamiento temprano de la artritis reumatoide pueden mejorar el pronóstico en la mayoría de los pacientes. El desarrollo de nuevas políticas de salud pública basadas en la prevención de la cavidad bucal son necesarias para mejorar la calidad de vida de los pacientes.

ABSTRACT

Abstract The aim of this study was to determine the prevalence of dental trauma in schoolchildren 6 to 12 years of age and associated clinical, sociodemographic, and socioeconomic variables. A cross-sectional study was conducted in 477 children from public elementary schools in four locations in Mexico. The dependent variable was dental trauma, which was dichotomized in 0 = without dental trauma and 1 = with dental trauma. For the statistical analysis, a multivariate binary logistic regression model was generated in Stata. Average age was 9.06±1.94 years and 51.1% were girls. The prevalence of dental trauma was 18.2%. Falls, automobile accidents and sports had the highest number of instances (p < 0.01). In the multivariate model, it was observed that the risk of dental trauma increased with age (OR = 1.28) and among boys (OR = 1.45). Schoolchildren with decreased overjet (OR = 0.38) had lower dental trauma. Father's age (OR = 1.03) and educational level (OR = 1.78) were associated with dental trauma. Schoolchildren without health insurance (OR = 0.62) presented dental trauma less often. This study provided important information regarding the association of different sociodemographic, socioeconomic and clinical variables with dental trauma in Mexican schoolchildren. Identifying factors associated with dental trauma may support health promotion opportunities to ameliorate the prevalence of dental trauma.

ABSTRACT

ABSTRACT: Evaluate the effect on the shear bond strength (SBS) of 5% NaOCl applied after acid etching on ground anterior teeth with fluorosis and analyze the surface with scanning electron microscopy (SEM), also compare fluorotic and healthy ground enamel by atomic force microscopy (AFM) and Vickers microhardness (VM). For the SBS test 30 anterior teeth with moderate and severe fluorosis according Dean index were selected by an examiner previously calibrated with an expert in fluorosis by using the intraclass correlation coefficient (ICC). With the help of a calibrated high speed diamond bur for veneer preparation and a parallel chamfer high speed diamond bur he vestibular face was prepared with a uniform reduction of .3 mm under water cooling. In one half of the vestibular face of the teeth the conventional adhesive procedure was carried out while in the other half was added an additional step with 5% NaOCl applied for 1 minute and washing after acid etchant. A resin post was adhered in each half and load was applied until fracture. The failure mode was evaluated and a SEM analysis was made. Posteriorly 10 samples of fluorotic and healthy ground enamel were used to measure the nanostructural characteristics by AFM (roughness average and absolute depth profile) and the VM in three operative steps (after ground, after etchant and after deproteinization). The Shapiro-Wilks and Brown-Forsythe methods were used to test the distribution of variables. The Paired Student's t-test was used to compare the differences between mean bond strength (MPa) in the two groups for SBS test. Chi- square analyzes were performed to compare the failure modes between groups. One- way ANOVA analysis and Tukey-Kramer post hoc test were used to compare groups for roughness average, absolute depth profile and Vickers microhardness. A greater SBS (32.17±4.20 MPa) and a surface more homogeneous and less contaminated were observed in the deproteinization subgruoup compared to the conventional subgroup (27.74±4.88 MPa). AFM parameters were greater in fluorosis subgroup than in healthy enamel subgroup. VM was lower in the fluorotic enamel in each operative step in comparation with healthy enamel. The use of 5% NaOCl as a deproteinizing agent after acid etchant in ground fluorotic enamel results in better adhesion, which may imply greater success in adhesive treatments. The ground surface of fluorotic enamel shows higher values of roughness and depth and lower values of VM which proves that there is a more irregular and less hard surface.


RESUMEN: Evaluar el efecto en la resistencia adhesiva al cizallamiento (SBS) de la aplicación de 5% de NAOCl después del grabado ácido en dientes anteriores fluoróticos tallados y analizar la superficie con microscopía electrónica de barrido (SEM), también comparar esmalte tallado fluorótico y sano por microscopía de fuerza atómica (AFM) y microdureza Vickers (VM). Para la prueba SBS 30 dientes anteriores con fluorosis moderada y severa de acuerdo al índice de Dean fueron seleccionados por un examinador previamente calibrado por un experto en fluorosis usando el coeficiente de correlación intraclase (ICC). La cara vestibular se preparó .3mm con la ayuda de una fresa calibrada para la preparación de carillas y una paralela con punta en chamfer de diamante a alta velocidad e irrigación. En una mitad de la superficie vestibular de los dientes se llevó a cabo el procedimiento adhesivo tradicional, mientras que en la otra mitad se incluyó un paso adicional con la aplicación de NaOCl al 5% por un minute y lavado posterior al grabado ácido. Un poste de resina fué adherido en cada mitad y se aplicó carga hasta la fractura. Se evaluó el modo de fallo y se realizó un análisis con SEM. Posteriormente se utilizaron 10 muestras de esmalte tallado fluorótico y sano para medir las características nano estructurales por medio de AFM (rugosisdad promedio y perfil de profundidad absoluta) y la VM en tres diferentes pasos operativos (posterior al tallado, posterior al grabado ácido y posterior a la desproteinización). Se utilizaron los métodos de Shapiro Wilks y Brown-Forsythe para conocer la distribución de las variables. Una T de student pareada se utilizó para comparar la diferencia entre los promedios de la fuerza de unión (MPa) entre grupos para la prueba SBS. Se llevaron a cabo análisis de chi cuadrada para comparer los modos de fallo entre los grupos. Análisis de ANOVA de una vía y Tukey-Kramer post hoc fueron utilizados para comparar los grupos para las variables rugosidad promedio, perfil de profundidad absoluta y microdureza Vickers. Se observó una mayor SBS (32,17±4,20 MPa) y una superficie más homogénea y menos contaminada en el subgrupo con desproteinización en comparación con el subgrupo convencional (27,74±4,88 MPa). Los parámetros de AFM fueron mayores en el subgrupo de fluorosis que en el subgrupo de esmalte sano. La VM fue más baja en el esmalte fluorótico en cada paso operativo en comparación con el esmalte sano. El uso de NaOCl al 5% como agente desproteinizante después del grabado ácido en el esmalte fluorótico tallado da como resultado una mejor adhesión, lo que puede implicar un mayor éxito en los tratamientos adhesivos. La superficie tallada del esmalte fluorótico muestra valores más altos de rugosidad y profundidad y valores más bajos de VM lo que prueba que existe una superficie más irregular y menos dura.

ABSTRACT

Abstract The aim of this study was to identify if the prevalence of dental pain (past and / or present) is associated with caries experience in Mexican children, as well as to characterize factors associated with dental pain. A cross-sectional study was conducted in a consecutive sample of 309 children 2 to 12 years old who were patients at a dental school clinic in Toluca, Mexico. Data were collected from clinical records. The dependent variable had three categories: 0 = have never had dental pain, 1 = had dental pain before the appointment, and 2 = current dental pain. Non-parametric statistical tests were used in the analysis. A multivariate multinomial logistic regression model was generated in Stata 11.0. Average age was 5.71 ± 2.43 years and 50.8% were boys. The joint dmft+DMFT index was 9.11 ± 4.19. It was observed that 56.6% of children did not report having experienced dental pain, 30.7% reported having previously had dental pain, and 12.6% had pain when the clinical appointment took place. In the multivariate model, variables associated (p < .05) with previous dental pain were age (OR = 1.13); the dmft + DMFT index (OR = 1.13), having had a last dental visit for curative/emergency reasons (OR = 2.41) and prior experience of dental trauma (OR = 2.59). For current pain, only the joint dmft + DMFT index (OR = 1.10, p < 0.05) had significant associations. Almost half of the children had experienced dental pain in their lifetime. Since caries experience is a factor associated with dental pain, decreasing caries levels may ameliorate suffering from dental pain in children.

ABSTRACT

Abstract The aim of the present study was to identify the relationship between the expression of calcitonin gene-related peptide (CGRP) and the responses of pulp sensitivity tests in healthy pulps and irreversible pulps by performing a cross-sectional study on patients. Two hundred subjects were evaluated. A total of 75 subjects complied with the criteria. The participants were divided into two groups: a) Healthy pulp (subjects [n = 35] having posterior teeth with clinically normal pulp tissue), and b) Irreversible pulpitis (subjects [n = 40] having posterior teeth with irreversible pulpitis). All participants were evaluated using the following variables: a) medical and dental history, b) pulp sensitivity tests, c) expression of CGRP by the enzyme-linked immunosorbent assay (ELISA), and d) expression levels of mRNA CGRP and mRNA CGRP receptor genes. We determined that the responses of the cold test between 4 and ≥12 s presented a higher average of the expression of CGRP in the group having irreversible pulpitis (p = 0.0001). When we compared the groups with the value of the electrical impulse, we found statistically significant differences (p = 0.0001), observing positive responses to the test with electrical impulses of 7 to 10, with an average of 72.15 ng/mL of CGRP in the irreversible pulpitis group. High values of CGRP expression were observed in that group in the responses of pulp sensitivity.

ABSTRACT

Abstract A test frequently used to complement endodontic diagnoses is the cold test; however, in the last 20 years, authors have reported incorrect results within pulp sensitivity tests. Specifically, a high frequency of false results in posterior teeth, were found. The aim of this study was to identify the most appropriate site for the cold test in molar teeth with a need for endodontic treatment, calculating predictive values, accuracy and reproducibility. A cross-sectional study was performed, evaluating 390 subjects. A total of 152 subjects of both genders from the ages of 15-65 years old participated. The ideal standard was established by direct pulp inspection, and the cold test agent used was 1,1,1,2-tetrafluoroethane. The patients were divided into four groups in relation to the molar tooth: (1) mandibular first molar, (2) mandibular second molar, (3) maxillary first molar, and (4) maxillary second molar. 169 teeth and 676 sites were studied. (a) The most appropriate sites for cold test were the middle third of the buccal surface and cervical third of the buccal surface in the mandibular molars with the following results: Middle third of the first molar: Accuracy 0.93, positive predictive value 0.90 and negative predictive value 0.96. Middle third of the second molar: Accuracy 0.93, positive predictive value 1.00 and negative predictive value 0.90. In relation to third cervical the results were: First molar: Accuracy 0.93, positive predictive value 0.89 and negative predictive value 0.97 y second molar: Accuracy 0.93, positive predictive value 1.00 and negative predictive value 0.90. (b) The highest reproducibility was observed in the middle third of the buccal surface with cervical third of the buccal surface in the mandibular second molar (1.00). The most appropriate site and reproducibility of the sites are auxiliary to complement endodontic diagnose with the cold test.


Resumen Una prueba frecuentemente utilizada para complementar los diagnósticos endodónticos es la prueba de frío. Sin embargo, en los últimos 20 años, los autores han reportado resultados incorrectos con las pruebas de sensibilidad pulpar. Específicamente, se ha observado una alta frecuencia de resultados falsos en dientes posteriores. El objetivo del estudio fue identificar el sitio más adecuado para la prueba de frío en dientes molares con necesidad de tratamiento endodóntico, calculando valores predictivos, exactitud y reproducibilidad. Se realizó un estudio transversal donde se evaluaron a 390 sujetos. 152 sujetos de ambos sexos de 15 a 65 años cumplieron con los criterios de inclusión. El estándar ideal que se utilizó en el estudio fue la inspección directa de pulpa en la cámara pulpar y la prueba de frío utilizada fue el 1,1,1,2-tetrafluoroetano. Los pacientes fueron divididos en cuatro grupos en relación al diente molar: (1) primer molar mandibular, (2) segundo molar mandibular, (3) primer molar maxilar, y (4) segundo molar maxilar. En el estudio se evaluaron 169 dientes con 676 sitios. (a) Los sitios más adecuados para la prueba de frío fueron el tercio medio y el tercio cervical de la superficie bucal en los molares mandibulares con los siguientes resultados: Tercio medio del primer molar: Exactitud 0.93, valor predictivo positivo 0.90 y valor predictivo negativo 0.96. Tercio medio del segundo molar: Exactitud 0.93, valor predictivo positivo 1.00 y valor predictivo negativo 0.90. En relación al tercio cervical los resultados fueron: Primer molar: Exactitud 0.93, valor predictivo positivo 0.89 y valor predictivo negativo 0,97 y segundo molar: Exactitud 0.93, valor predictivo positivo 1.00 y valor predictivo negativo 0.90. (b) La más alta reproducibilidad (1.00) se observó entre el tercio medio con el tercio cervical de la superficie bucal en el segundo molar inferior. El sitio más apropiado y la reproducibilidad de los sitios son auxiliares para complementar el diagnóstico endodóntico con la prueba de frío.

ABSTRACT

ABSTRACT Background: Systemic blockade of TNF-α in Rheumatoid arthritis with insulin resistance seems to produce more improvement in insulin sensitivity in normal weight patients with Rheumatoid arthritis than in obese patients with Rheumatoid arthritis, suggesting that systemic-inflammation and obesity are independent risk factors for insulin resistance in Rheumatoid arthritis patients. Objectives: To evaluate the insulin resistance in: normal weight patients with Rheumatoid arthritis, overweight patients with Rheumatoid arthritis, obese Rheumatoid arthritis patients, and matched control subjects with normal weight and obesity; and its association with major cytokines involved in the pathogenesis of the disease. Methods: Assessments included: body mass index, insulin resistance by Homeostasis Model Assessment, ELISA method, and enzymatic colorimetric assay. Results: Outstanding results from these studies include: (1) In Rheumatoid arthritis patients, insulin resistance was well correlated with body mass index, but not with levels of serum cytokines. In fact, levels of cytokines were similar in all Rheumatoid arthritis patients, regardless of being obese, overweight or normal weight (2) Insulin resistance was significantly higher in Rheumatoid arthritis with normal weight than in normal weight (3) No significant difference was observed between insulin resistances of Rheumatoid arthritis with obesity and obesity (4) As expected, levels of circulating cytokines were significantly higher in Rheumatoid arthritis patients than in obesity. Conclusions: Obesity appears to be a dominant condition above inflammation to produce IR in RA patients. The dissociation of the inflammation and obesity components to produce IR suggests the need of an independent therapeutic strategy in obese patients with RA.


RESUMO Introdução: O bloqueio sistêmico do Fator de Necrose Tumoral-α (TNF-α) nos indivíduos com artrite reumatoide (AR) com resistência à insulina (RI) parece produzir mais melhoria na sensibilidade à insulina em pacientes com AR com peso normal do que em pacientes obesos com AR. Isso sugere que a inflamação sistêmica e a obesidade são fatores de risco independentes para a RI em pacientes com AR. Objetivos: Avaliar a resistência à insulina em pacientes com peso normal com AR (AR-PN), pacientes com sobrepeso com AR (AR-SP), pacientes com AR obesos (AR-OB) e indivíduos controle com peso normal (PN) e obesidade (OB) pareados; e a associação com as principais citocinas envolvidas na patogênese da doença. Métodos: As avaliações incluíram: índice de massa corporal (IMC), resistência à insulina com o modelo de avaliação da homeostase (Homa-IR), método Elisa e ensaio colorimétrico enzimático. Resultados: Os resultados marcantes do presente estudo incluíram: (1) Em pacientes com AR, a RI estava bem correlacionada com o Índice de Massa Corporal (quanto maior o IMC, maior a RI), mas não com os níveis séricos de citocinas. Na verdade, os níveis de citocinas eram semelhantes em todos os pacientes com AR, independentemente de serem obesos, com sobrepeso ou peso normal. (2) A RI foi significativamente maior no grupo AR-PN do que no grupo PN. (3) Não houve diferença estatisticamente significativa entre a RI de pacientes AR-OB e OB. (4) Como esperado, os níveis circulantes de citocinas foram significativamente maiores em pacientes com AR do que em OB. Conclusões: A obesidade parece ser uma condição mais importante do que a inflamação em produzir RI em pacientes com AR. A dissociação dos componentes da inflamação e da obesidade na produção de RI sugere a necessidade de uma estratégia terapêutica independente em pacientes obesos com AR.

ABSTRACT

El efecto Doppler es la base científica de la flujometría láser Doppler. El efecto fue descrito por primera vez en el año de 1842 por el físico austriaco Christian Doppler en su tratado Über das farbige licht der doppelsterne und einige andere gestirne des himmels (Sobre el color de la luz en estrellas binarias y otros astros). Este principio ha permitido desarrollar técnicas y aparatos que han sido empleados en el ramo médico para medir la perfusión en diversos órganos y tejidos del cuerpo, y que han sido útiles como método diagnóstico. En la odontología, poco a poco comienza a reportarse información acerca del uso del Doppler en las diversas estructuras bucodentales, y ha demostrado ser no invasivo y de gran utilidad diagnóstica. Son pocos los estudios reportados en la rama de la odontología en cuanto a esta nueva tecnología; es importante comenzar líneas de investigación apoyadas en ella para beneficio de los pacientes.


The Doppler eff ect, the scientifi c basis of laser Doppler fl owmetry, wasfi rst described in 1842 by Austrian physicist Christian Doppler in histreatise Über das farbige Licht der doppelsterne und einige andere gestirnedes Himmels (On the Colored Light of the Binary Stars and SomeOther Stars of the Heavens). This principle has led to the developmentof techniques and devices that have been used in the fi eld of medicineto measure perfusion in various organs and tissues, and have provideda useful method of diagnosis. In dentistry, information on the use ofthis method in the various structures of the mouth has slowly begunto be published. As a result, the need for its continued use in the fi eldof oral health has become evident, given that it has proven to be noninvasiveand extremely useful in diagnosis. It is a diagnostic technique that is commonly used in healthcare and has been widely developedin the fi eld of medicine, yet there have been few reported studies of it suse in dentistry, which is an important step towards opening new linesof research based on this new technology for the benefi t of patients.

ABSTRACT

Diversos estudios han demostrado mayor o menor grado de afectacióndel esmalte después del uso de los distintos tratamientos para blanqueamiento dental. Por este motivo, se han propuesto varios métodos ytratamientos remineralizantes que pudieran revertir los efectos negativosde dicho tratamiento. El objetivo del presente trabajo fue evaluar el efecto del Opalescence PF 15 por ciento (peróxido de carbamida al 15%) y delremineralizante Flor-Opal (NaF al 1.1 por ciento), ambos de la casa comercialUltradent, así como de la saliva artifi cial sobre la microdureza y la micromorfología del esmalte humano. Se utilizaron 10 incisivos centrales superiores recién extraídos provenientes de centros de salud del Puerto de Veracruz, México. Réplicas de estos dientes fueron obtenidas en lasdiferentes fases del tratamiento de blanqueamiento para ser posteriormente observadas en el microscopio electrónico de barrido (MEB). Asimismo, se realizaron mediciones de microdureza en la superficie del esmalte de los dientes seleccionados durante las diferentes fases del tratamiento de blanqueamiento. Se observó que la microdureza del esmalte se ve disminuida (aunque no significativamente) después de la aplicación del peróxido de carbamida al 15 por ciento, y vuelve a subir después de la aplicación de los remineralizantes, para posteriormente volver a descender siete días después del uso de los mismos. Los datos de microdureza coincidieron con los de micromorfología obtenidos enel MEB. Se concluye que el peróxido de carbamida al 15 opr ciento sí afecta lamicromorfología de la superficie del esmalte, además de que disminuyela microdureza del mismo. Con el uso del remineralizante Flor-Opal se onsiguieron mayores valores de microdureza y mejores características micromorfológicas comparado con la saliva artificial.


Studies have shown varying degrees of involvement of the enamel following the use of tooth-whitening treatments. Consequently, a range of methods and remineralizing treatments have been proposed to reverse their negative effects. The aim of this study was, therefore, to evaluate the effect of Opalescence PF 15% (carbamide peroxide 15%) and the remineralizing treatment Flor-Opal (1.1% NaF), both produced by Ultradent, as well as artifi cial saliva on the microhard-ness and micromorphology of human enamel. Ten recently-extracted central incisors from health centers in the port of Veracruz, Mexico, were used. Replicas of these teeth were made at the various stages of the whitening treatment in order to observe these under a scanning electron microscope (SEM). Microhardness measurements were also taken on the surface of the enamel of the teeth selected at each of the various stages of the whitening treatment. The microhardness of the enamel was found to decrease (though not signifi cantly) after the ap-plication of carbamide peroxide 15%, then increase again following the application of the remineralizing agents, only to decrease again seven days after these were applied. The microhardness data coincided with that for micromorphology obtained from the SEM. We conclude that carbamide peroxide 15% does affect the micromorphology of the enamel surface and also decreases its microhardness. Flor-Opal produced higher microhardness values and better micromorphological characteristics compared to artifi cial saliva.

ABSTRACT

El objetivo de este estudio fue estimar la prevalencia de pérdida de dientes (PD) permanentes en una población universitaria de adolescentes y adultos jóvenes, así como conocer su distribución por edad y sexo. Se realizó un estudio transversal en una muestra de 1027 adolescentes y adultos jóvenes de 16 a 25 años de edad seleccionados aleatoriamente del total de aspirantes a las licenciaturas de la Universidad Autónoma de San Luis Potosí, México. La variable dependiente fue la prevalencia de PD, codificándose como 0=sujetos sin PD y 1=sujetos que tuvieron al menos un diente perdido. Otras variables incluidas fueron edad y sexo del sujeto. El análisis se llevó a cabo en STATA v9,0 con regresión logística. El promedio de edad de los sujetos incluidos fue de 18,20±1,65 y 52,0% fueron hombres. La prevalencia de sujetos con PD fue de 18,0% (n=185) y el promedio de 0,46±1,13, mientras que en quienes tuvieron al menos uno perdido fue de 2,54±1,32. El número máximo de PD fue de 5. En el modelo ajustado obtuvimos significancia estadística en la edad (RM=1,11; p<0,05). Las mujeres tuvieron 41% mayor riesgo de presentar al menos un diente perdido que los hombres. Los sujetos que presentaron más de 6 obturaciones tuvieron mayor posibilidad de tener dientes perdidos (RM=1,60; p<0,05). Los hallazgos indican que la experiencia de tener PD alcanza casi el 20%, además se mostró una asociación entre la PD con la edad, el sexo y el número de obturaciones. Este estudio demuestra la existencia de desigualdades de género.


The objective of this study was to estimate the prevalence of permanent teeth loss in a university population of adolescents and young adults, and also to determine the distribution by age and sex. A cross-sectional study was carried out in a sample of 1027 adolescents and young adults from 16 to 25 years old selected randomly from the total number of applicants to the bachelor's degree program of San Luis Potosi University, Mexico. The dependent variable was the prevalence of tooth loss, codified as "0"=subjects without tooth loss and "1"=subjects with at least one tooth loss. Others variables included were age and sex. Analyzes was performed in STATA 9.0 with logistic regression. The mean of age was 18.20±1.65 and 52.0% were men. The prevalence of tooth loss was 18.0% (n=185) and the mean of 0.46±1.13, whereas in subjects with at least one tooth loss the mean was 2.54±1.32. The maximum number of teeth loss was 5. In the adjusted model we obtained statistic significance in the age (OR=1.11; p<0.05). Women have 41% high risk to present at least one tooth loss than men. Subjects that presented more of 6 filling have high possibility to have teeth loss (OR=1.60; p<0.05). Findings indicate that the experience to have tooth loss reaches nearly 20.0%, and that there was relationship between tooth loss and age, sex and number of fillings. This study demonstrates the existence of gender inequalities.

ABSTRACT

The aim of this study was to examine the association between overweight-obesity and periodontal disease in subjects who attended the clinic of Periodontics, Faculty of Dentistry, San Luis de Potosi, Mexico. This was cross-sectional study involving 88 subjects - 60 without overweight-obesity and 28 with overweight-obesity. The following clinical parameters were evaluated: dental bacterial plaque, index of calculus, gingivitis, probing depth and periodontal disease index (PDI). When comparing the group of subjects with overweight-obesity to the control, there were statistically significant differences in the variables calculus (p=0.0015), gingivitis (p=0.0050) and periodontal disease (p=0.0154). Regarding the logistic regression analysis, the dependent variable was subjects with and without overweight-obesity and the independent variables were sex, age and periodontal disease. We found statistically significant differences (p=0.0162) with OR=3.16 in periodontal disease. Periodontal disease showed statistically significant differences in the group of subjects with overweight-obesity. The oral health of subjects with overweight- obesity should be supervised and checked in order to prevent oral alterations.


El objetivo fue asociar el sobrepeso-obesidad con la enfermedad periodontal en sujetos que asistieron a la clinica de Periodoncia de la Facultad de Estomatologia de la Universidad Autonoma de San Luis Potosi (UASLP) Mexico. Se realizo un estudio transversal con un total de 88 sujetos, 60 con sobrepeso-obesidad y 28 sin sobrepeso-obesidad. Los siguientes parametros clinicos fueron evaluados en el estudio: placa dentobacteriana, indice de calculo, profundidad de bolsa y enfermedad periodontal (PDI). Al comparar el grupo de sujetos con sobrepeso-obesidad con el control se encontraron diferencias estadisticamente significativas en las variables calculo (p=0.0015), gingivitis (p=0.0050) y enfermedad periodontal (p=0.0154). En relacion con el analisis de regresion logistica, la variable dependiente fue sujetos sin y con sobrepeso-obesidad y las independientes fueron: sexo, edad y enfermedad periodontal. Encontramos diferencias estadisticamente significativa (p=0.0162) con un OR=3.16 en enfermedad periodontal. La enfermedad periodontal mostro diferencias al comparar el grupo de sujetos con sobrepeso-obesidad con el control. Es necesario la prevencion, supervision y revision del estado de salud bucal de los pacientes con sobrepeso y obesidad para prevenir alteraciones bucales.

ABSTRACT

Objective Determining dental caries' experience, prevalence and severity in students applying for degree courses at San Luis Potosi University (UASLP). Material and Methods A cross-sectional study was carried out involving adolescents and young adults (16 to 25 years old) applying for undergraduate courses at UASLP (~10 percent, n=1 027). Two standardized examiners undertook dental examinations; DMFT index, prevalence (DMFT>0), severity (DMFT>3 and DMFT>6) and significant caries index (SiC) were calculated. STATA 9.0 non-parametric tests were used for statistical analysis. Results Mean age was 18.20±1.65; 48.0 percent were female. The DMFT index was 4.04±3.90 and caries prevalence was 74.4 percent. Regarding caries' severity, 48.8 percent had MDFT>3 and 24 percent DMFT>6. The SiC index was 8.64. Females had higher caries experience than males (4.32±4.01 cf 3.78±3.78; p<0.05), but similar prevalence and severity (p>0.05). Age was associated with both experience (p<0.001) and prevalence (p<0.01) and to differing degrees of caries' severity (p<0,001). The ®filled teeth¼ component had the highest DMFT index percentage (63.6 percent) and ®missing teeth¼ the lowest (11.4 percent). Conclusions High dental caries' experience, prevalence and severity were observed in this sample of adolescents and young adults. Restorative experience was high (59.5 percent) compared to studies carried out in other parts of Mexico and Latin-America.


Objetivo Determinar la experiencia, prevalencia y severidad de caries en aspirantes a las licenciaturas de la Universidad Autónoma de San Luis Potosí (UASLP). Material y Métodos Se realizó un estudio transversal descriptivo en el 2007 en una muestra de adolescentes y adultos jóvenes de 16 a 25 años de edad aspirantes a las licenciaturas de la UASLP (~10 por ciento, n=1 027). El examen clínico lo realizaron dentistas. Se calcularon los índices de caries para dentición permanente y se determinó la experiencia (índice global CPOD), la prevalencia (CPOD>0) y la severidad (CPOD>3 y CPOD>6) de caries dental, además, del índice de caries significativa (SiC). Los análisis estadísticos se realizaron con X2, Mann-Whitney, y pruebas de tendencia no paramétrica en STATA 9.0. Resultados La edad promedio fue 18,20±1,65 años. El 48,0 por ciento fueron mujeres. El índice CPOD fue 4,04±3,90 y la prevalencia de caries de 74,4 por ciento. En cuanto a la severidad, 48,8 por ciento tuvieron CPOD >3 y 24,0 por ciento CPOD >6. El índice SiC fue de 8,64. Las mujeres tuvieron mayor experiencia de caries que los hombres (4,32±4,01 vs 3,78±3,78; p<0,05); pero similar prevalencia y severidad (p>0,05). La edad se asoció tanto a la experiencia (p<0,001), como a la prevalencia (p<0,01) y a los diferentes grados de severidad de caries (p<0,001). El mayor porcentaje (63,6 por ciento) del índice CPOD fue del componente ®dientes obturados¼ y el menor (11,4 por ciento) del componente "dientes perdidos". Conclusiones Se observó una alta experiencia, prevalencia y severidad de caries en esta muestra de adolescentes y adultos jóvenes. Por otro lado, la experiencia restauradora fue alta (59,5 por ciento) en comparación con estudios realizados en otros lugares de México y Latinoamérica.

ABSTRACT

La finalidad del presente trabajo fue determinar la frecuenciade la caries, enfermedad periodontal y dientes perdidos en pacientes diabéticos tipo 1 y 2. Se realizó un estudio transversal con un total de 175 sujetos, 105 pacientes diabéticos y 70 sujetossin diabetes, distribuidos en los siguientes grupos: 1) 35 pacientes diabéticos tipo 1 (con valores de hemoglobina glucosilada de 6.5 a 7 por ciento), 2) 35 pacientes diabéticos tipo 1 (con valores de hemoglobina glucosilada mayores de 7 por ciento), 3) 35 sujetos sin diabetes mellitus tipo 1, 4) 35 pacientes diabéticos tipo 2 y 5) 35 sujetos sin diabetes mellitus tipo 2. Los sujetos se seleccionaron con un muestreo no probabilístico consecutivo. Los siguientes parámetros clínicos se evaluaron en todos los sujetos que participaron en el estudio: frecuencia de caries, dientes obturados, perdidos, restauraciones con prótesis (fija, removible y dentaduras completas), placa dentobacteriana, índice de cálculo, profundidad de bolsa y la pérdida de nivel de inserción epitelial. Al comparar los grupos de los pacientes diabéticos tipo 1 y el control no se encontramos diferencias estadísticamentesignificativas en todas las variables del estudio. Al comparar el grupo de pacientes diabéticos tipo 2 con el control se encontraron diferencias en las variables dientes perdidos (p=0.0134),cálculo (p=0.0001), profundidad de bolsa (p=0.0009) y pérdida de nivel de inserción epitelial (p=0.0093). La enfermedad periodontal mostró diferencias al comparar el grupo de pacientes diabéticos tipo 2 con el control. Es necesario la prevención,supervisión y revisión del estado de salud bucal de los pacientes diabéticos (tipo 1 y 2) para prevenir alteraciones bucales.

ABSTRACT

OBJECTIVE: To compare the frequency of periodontal disease in type 1 diabetes mellitus patients with and without metabolic control, having a control group of healthy patients. MATERIAL AND METHODS: A prolective cross sectional study with simple random sampling was carried out; patients were divided in three groups: A). Forty healthy subjects, B). Twenty diabetic patients with metabolic control, and C). Twenty diabetic patients without metabolic control. The diabetic subjects were evaluated with glycosylated hemoglobin (GHb) to determine the glucose control; clinical periodontal evaluations were performed for all teeth in each subject and following indexes were included: Plaque, gingival, mobility, probing depth, attachment level, bleeding on probing, and marginal bone loss. RESULTS: The imbalance of glucose of subjects with diabetes mellitus type 1 was associated with more frequency of periodontal disease (p < 0.05). CONCLUSION: The population of type 1 diabetes mellitus with imbalance of glucose showed association with periodontal disease.

ABSTRACT

Objetivo. Conocer el uso y verificar los ciclos de esterilización con indicadores biológicos en los equipos utilizados por cirujanos dentistas de la Facultad de Estomatología de la Universidad Autónoma de San Luis Potosí (UASLP) y del Colegio Dental Potosino. Material y métodos. Estudio transversal hecho en 1999-2000. El 65 por ciento (n=130) de los odontólogos participaron con un esterilizador, la verificación se realizó por indicadores que contenían esporas de Bacillus subtilis y de Bacillus stearothermophilus. Resultados. Participaron 30 autoclaves y 100 esterilizadores de calor seco, 23 de ellos (17.7 por ciento) presentaron crecimiento bacteriano; el 16.1 por ciento (n=21) de los participantes utilizan los indicadores biológicos como verificador. Los dos métodos de esterilización presentaron crecimiento bacteriano con frecuencias similares (p=>0.66). Conclusiones. Pocos cirujanos dentistas verifican su esterilizador con indicadores biológicos en los equipos que presentaron crecimiento bacteriano, sus fallas se encontraron en el proceso de esterilización.
