RESUMO

The metal alloys used in dentistry are made mainly of nickel (Ni), titanium (Ti), and other elements such as molybdenum (Mo), zirconium (Zr), iron (Fe), tin (Sn), chrome (Cr), carbon (C), copper (Cu) and niobium (Nb) which can release metal ions in unstable environments. The aim of this work was determine the salivary pH before and during orthodontic treatment; evaluate the release of metal ions, mainly Ni and Ti, in urine and saliva using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES); and evaluate the corrosion using Scanning Electronic Microscopy (SEM). In this study, we selected 35 individuals under orthodontic treatment, from whom saliva and urine samples were collected in 3 stages: (a) basal, (b) at 3 and (c) 6 months after the placement of the fixed appliances. SEM analyzed the Ni-Ti (0.016″) and stainless steel (SS) (0.016 × 0.022″) archs after 1 month of being in contact with the oral cavity. Statistical analysis was performed with Stata using the ANOVA model of repeated measures with a p < 0.05. A statistically significant difference in the concentration of Ni in saliva were found between 3 and 6 months of intervention and Ti in urine was found 3 and 6 months.

RESUMO

OBJECTIVE: To identify the prevalence of and factors associated with the use of dental health services to receive professionally applied topical fluoride (DHSU-PATF) in the 12 months prior to the study among Mexican schoolchildren aged 6 to 12 years. METHODS: A cross-sectional study was performed in 1,404 schoolchildren selected randomly from 15 public schools in the city of Pachuca, Mexico. Questionnaires were distributed to determine the demographic, socioeconomic, and behavioral variables. The dependent variable was the DHSU-PATF in the year before the study, which was dichotomized as 0 (no DHSU-PATF) or 1 (yes, DHSU-PATF). We calculated odds ratios (OR) and 95% confidence intervals. The analysis was performed in Stata 11.0. RESULTS: The prevalence of DHSU-PATF was 5.1%, but lower among younger children (OR = 0.86) and greater among children with health insurance (private insurance, OR = 3.64; insurance provided by the government owned oil company, the Army, or the Navy, OR = 5.03). The level of knowledge about oral health among guardians/ parents was also a factor (medium, OR = 2.37; high, OR = 4.05). Additionally, among the children whose parents/guardians perceived them (the children) as having good or very good oral health, the OR was 3.33; among children whose parents brushed their teeth with greater relative frequency, the OR was 8.74. Finally, DHSU-PATF was greater among children with relatively higher socioeconomic status (2nd quartile, OR = 3.29; 3rd quartile, OR = 5.99; 4th quartile, OR = 4.64). CONCLUSION: The receipt of PATF was low in this sample of Mexican schoolchildren and is associated with socioeconomic and behavioral factors. This gives us a guideline to create or improve topical fluoride application strategies in the public and private Mexican health systems.

RESUMO

PURPOSE: The aim of this paper was to compare three conventional hand mixing glass-ionomer cements (GICs) and a new mechanical mixing glass-ionomer cement. MATERIALS AND METHODS: Samples were measured on days 1, 2, 6, 10, 31, 90 and 180. After 32 and 181 days of monitoring, the samples were recharged by using 1 ml of 2% sodium fluoride gel. RESULTS: The fluoride release started in high concentration during the first day for all GICs, with a value for GIII of 32.6 ppm. From the 2nd day, a slow, steady decline, with the exception of GII, which showed a marked decline to a value of 3.2 ppm. Analysis of variance (ANOVA) test showed statistically significant differences between the amounts of fluoride of the four materials in the first 24 h. Student t test was used to compare the fluoride release between the first and second recharge in each one of the study groups. Statistically significant differences were found when we compared the fluoride release in groups I (t = -16.95, p = 0.000) and IV (t = -2.644, p = 0.26). CONCLUSIONS: A mechanical mixing was the material with the more constant fluoride release and after recharge showed the highest fluoride release which make it an important benefit for clinicians.

RESUMO

ABSTRACT The aim of this study was to explore the remineralizing effect of toothpastes based on Xilitol, Camellia Sinensis and Juniperus Communis. An in vitro experimental study was carried out in an 18 human premolars sample, which were treated with one of the 3 evaluated toothpastes and a control fluoride one. The atomic percentages of Ca and P were evaluated by Energy Dispersive X-ray Spectroscopy (EDS). In addition, the enamel surface of treated teeth was visualized by Scanning Electron Microscopy (SEM). The evaluations were carried out in three stages: pre-treatment, after an artificial demineralization process and after the treatment with the toothpastes. In the statistical analysis, the one-way ANOVA and Pearson correlation tests were used. Xilitol and Juniperus Communis showed the greatest gain of P ions compared to the control group (p<0.01). As for Ca, the group treated with xylitol-based toothpaste showed more ion gain compared with the control group (p<0.01). In the Pearson correlation test between Ca and P, statistically significant correlations were observed in all groups (p<0.01), ranging between r=0.7413 (Xylitol Group) and r=0.9510 (Control Group). We concluded that Xylitol paste showed the highest remineralizing property, both in the EDS analysis and in the SEM images.


RESUMEN El objetivo de este studio fue explorer el efecto remineralizante de las cremas dentales compuestas de Xilitol, Camelia Sinensis y Juniperus Communis. Se llevó a cabo un estudio experimental in vitro en una muestra de 18 premolares humanos, los cuales fueron tratados con una de las tres pastas dentales evaluadas y una fluorada. Los porcentajes atomicos de Ca y P fueron evaluados por Espectroscopia de rayos X de energía dispersive (EDS). Además, la superficie del esmalte de los dientes tratados fue examinada por Microscopia Electronica de Barrido (SEM). Las evaluaciones fueron llevadas a cabo en tres etapas: pre-tratamiento, despues de un proceso artificial de desmineralizacion y después del tratamiento con las pastas dentales. Se usaron ANOVA de una via y correlacion de Pearson para el analisis estadistico. Xilitol y Juniperus Communis mostraron la mayor ganancia de iones P comparados con el grupo control (p<0.01), con rangos entre r=0.7413 (Grupo con Xylitol) and r=0.9510 (Group Control). Se concluyó que la pasta con Xilitol mostró las mayores propiedades remineralizantes, tanto en el analisis EDS y las imágenes SEM.

RESUMO

To evaluate the relationship between the Human Development Index (HDI) and its components with oral cancer (OC) in Latin America. Ecological study in 20 Latin American countries in 2010 and 2017, which evaluated the relationship between the Age-Standardized Rates (ASRs) of incidence and mortality from oral cancer and the following indicators: HDI, with its components (income, education, and health indexes); and the Gini and Theil-L indexes. Among the countries with the highest HDI, men from Brazil and Cuba had the highest incidence and mortality ASRs per 100,000 inhabitants (ASR incidence >7.5 and mortality >4.5). Among those with the lowest HDI, Haiti was the most affected country (ASR incidence >4.1 and mortality >3.0). The highest male:female ratio was in Paraguay in both years (incidence >3.5 and mortality >4.0). Mortality from oral cancer is negatively related to the global HDI in both years, with regression coefficients (95% confidence interval) being -5.78 (-11.77, 0.20) in 2010 and -5.97 (-11.38, -0.56) in 2017; and separate (independent) from the income [-4.57 (-9.92, 0.77) in 2010 and -4.84 (-9.52, -0.17) in 2017] and health indexes [-5.81 (-11.10, -0.52) and -6.52 (-11.32, -1.72) in 2017] (p < 0.05) in the countries with lower HDI. Oral cancer incidence and mortality rates vary both among and within Latin American countries according to sex, with a greater burden on men. The HDI is negatively related to mortality from oral cancer in the countries of medium and low HDI.

RESUMO

OBJECTIVE: Mortality from oral cancer, the prevalence of the main risk factors and the implementation of policies to control current trends and the distribution of data among the countries of Latin America. The objective of this study was to describe the trends of mortality from oral cancer between 2000 and 2017, by sex, in 20 countries in Latin America, and to know the effect of measures to control tobacco consumption and alcohol consumption on the Mortality from oral cancer. METHODS: Ecological study that evaluates the relationship between the rates standardized by the age of cancer by oral sex, the prevalence of tobacco consumption and alcohol consumption, and the implementation of control policies. To calculate the annual percentage change of the rates, the Prais-Winsten regression was used; and the effect of measures of control of risk factors on oral cancer mortality is assessed by Spearman correlations. RESULTS: The greatest decreases in oral cancer mortality were in men in Brazil (APC -7.83, -14.25,-0.93). Mortality from cancer the oral relationship between men and the prevalence of tobacco consumption and alcohol consumption (r = 0.358, r 0.537) (p <0.01), and between the non-implementation of control policies of smoking (r = 0.738) (p= 0.003), the restrictions on the hours and days of sale of alcohol (r = 0.777, p = 0.001), and the states on sponsorship and promotion of alcohol sales (r =0.739 , p =0.040). CONCLUSIONS: The effect of the implementation of control policies is evidenced by a greater relationship with oral cancer mortality in the countries with the least progress in their execution.

RESUMO

INTRODUCTION: Dental caries is the most frequent oral disease worldwide and the main cause of tooth loss in children and young adults. One of the most frequently affected areas is the occlusal surfaces of the first permanent molars (FPM) due to their morphological complexity. At present, several preventive treatments can reduce the incidence of this disease in school populations. In Mexico, the most commonly used technologies are those derived from some presentation of fluoride; on the other hand, research on this topic has been limited. OBJECTIVE: To determine the cost-effectiveness of two different methods for preventing the incidence of caries on the FPM of schoolchildren (6-8 years of age) from public primary schools. MATERIAL AND METHODS: This is a randomized experimental design. Participants will be assigned to two treatment groups of 114 each. In the first group, pit and fissure sealants will be applied, whereas the second group will receive a fluoride varnish. The work will be carried out in schoolchildren that attend public elementary schools in the state of Hidalgo, Mexico. The result variable will be the incidence of caries and the total cost of each of the interventions will be calculated in order to calculate the intervention's cost-effectiveness. CONCLUSION: This work will allow us to compare the cost-effectiveness of the pit and fissure sealants and the fluoride varnish in order to determine which offers the best results.

RESUMO

Dental caries-a highly prevalent public health problem in preschoolers and school children-is the main cause of premature dental loss during childhood, and this may be related to loss of space in the posterior sector. The objective of this study was to evaluate whether interproximal caries and premature tooth loss (D and/or E) are risk factors for loss of space in the posterior sector.A comparative cross-sectional study (split-mouth type) was performed in schoolchildren (6-8 years old). Seventeen gypsum models were evaluated. These children presented with unilateral loss of a dental organ or interproximal caries (teeth D and/or E) and without such affectations on the other side. Measurements were made with a digital Vernier caliper. The dependent variable was the difference (loss of space, mm) between the control and case sides. The independent variables were type of affectation (interproximal caries or tooth loss), sex, age, arcade, and number of interproximal surfaces affected.The mean age was 6.82 ±â€Š0.44 years and 64.7% were boys. The average space loss was 1.09 ±â€Š0.18 mm (control vs case; P < .0001). A greater loss of space was observed among those who lost a dental organ than those with interproximal caries (P = .0119). A correlation was observed between the variable loss of space and the number of interproximal surfaces affected (r = 0.5712, P = .0166).Interproximal caries and tooth loss were risk factors for loss of space in the posterior segment in this sample of Mexican schoolchildren.

RESUMO

OBJETIVO: La mortalidad por cáncer oral, la prevalencia de los principales factores de riesgo y la implementación de las políticas para su control presentan tendencias y distribución desiguales entre los países de América Latina. El objetivo de este trabajo fue describir las tendencias de la mortalidad por cáncer oral entre 2000 y 2017, según sexos, en 20 países de América Latina, y conocer el efecto de las medidas de control del consumo de tabaco y el consumo de alcohol sobre la mortalidad por cáncer oral. MÉTODOS: Estudio ecólogico que evaluó la relación entre las tasas estandarizadas por edad del fallecimiento por cáncer oral según el sexo, la prevalencia del consumo de tabaco y del consumo de alcohol,y la implementación de las políticas de control. Para calcular la variación porcentual de cambio anual de las tasas, se usó la regresión Prais-Winsten; y el efecto de las medidas de control de los factores de riesgo sobre la mortalidad por cáncer oral se evalúo mediante correlaciones de Spearman. RESULTADOS: Los mayores descensos en la mortalidad por cáncer oral fueron en los hombres de Brasil (APC -7,83; -14,25; -0,93). La mortalidad por cáncer oral mostró relación positiva entre hombres y la prevalencia del consumo de tabaco y del consumo de alcohol (r=0,358, r=0,537) (p<0,01), y entre la no implementación de las políticas de control de tabaquismo (r=0,738) (p=0,003), las restricciones en los horarios y días de venta de alcohol (r=0,737, p=0,001), y los reglamentos sobre patrocinio y promoción de venta de alcohol (r=0,739, p=0,040). CONCLUSIONES: El efecto de la implementación de las políticas de control se evidencia en una mayor relación con la mortalidad por cáncer oral en los países con menor avance en su ejecución

RESUMO

The objective of this study was to compare the differences between the measurements performed manually to those obtained using a digital model scanner of patients with orthodontic treatment.A cross-sectional study was performed in a sample of 30 study models from patients with permanent dentition who attended a university clinic between January 2010 and December 2015. For the digital measurement, a Maestro 3D Ortho Studio scanner (Italy) was used and Mitutoyo electronic Vernier calipers (Kawasaki, Japan) were used for manual measurement. The outcome variables were the measurements for maxillary intercanine width, mandibular intercanine width, maxillary intermolar width, mandibular intermolar width, overjet, overbite, maxillary arch perimeter, mandibular arch perimeter, and palate height. The independent variables, besides age and sex, were a series of arc characteristics. The Student t test, paired Student t test, and Pearson correlation in SPSS version 19 were used for the analysis.Of the models, 60% were from women. Two of nine measurements for pre-treatment and 6 of 9 measurements for post-treatment showed a difference. The variables that were different between the manual and digital measurements in the pre-treatment were maxillary intermolar width and palate height (P < .05). Post-treatment, differences were found in mandibular intercanine width, palate height, overjet, overbite, and maxillary and mandibular arch perimeter (P < .05).The models measured manually and digitally showed certain similarities for both vertical and transverse measurements. There are many advantages offered to the orthodontist, such as easy storage; savings in time and space; facilitating the reproducibility of information; and conferring the security of not deteriorating over time. Its main disadvantage is the cost.

RESUMO

In the present study, silver nanoparticles (AgNPs) were synthesized in situ on orthodontic elastomeric modules (OEM) using silver nitrate salts as metal-ion precursors and extract of the plant Hetheroteca inuloides (H. inuloides) as bioreductant via a simple and eco-friendly method. The synthesized AgNPs were characterized by UV-visible spectroscopy; scanning electron microscopy-energy-dispersive spectroscopy (SEM-EDS) and transmission electron microscopy (TEM). The surface plasmon resonance peak found at 472 nm confirmed the formation of AgNPs. SEM and TEM images reveal that the particles are quasi-spherical. The EDS analysis of the AgNPs confirmed the presence of elemental silver. The antibacterial properties of OEM with AgNPs were evaluated against the clinical isolates Streptococcus mutans, Lactobacillus casei, Staphylococcus aureus and Escherichia coli using agar diffusion tests. The physical properties were evaluated by a universal testing machine. OEM with AgNPs had shown inhibition halos for all microorganisms in comparison with OEM control. Physical properties increased with respect to the control group. The results suggest the potential of the material to combat dental biofilm and in turn decrease the incidence of demineralization in dental enamel, ensuring their performance in patients with orthodontic treatment.

RESUMO

OBJECTIVE: To identify dental pain prevalence and associated factors in Mexican schoolchildren. METHODS: This cross-sectional study included 1,404 schoolchildren aged 6 to 12 years from public schools in the city of Pachuca de Soto, Hidalgo, Mexico. Data were collected through a questionnaire that addressed sociodemographic and socioeconomic factors, eating and dental hygiene habits, and behavior variables. The dependent variable was self-reported dental pain in the 12 months prior to the survey. Data were analyzed using nonparametric statistics and a binary logistical regression model. RESULTS: Dental pain prevalence among the studied children was 49.9%. The variables associated in the final model (p < 0.05) were younger mother's age, higher socioeconomic level, absence of an automobile in the home, fried food, fruit intake, lower tooth brushing frequency, never having used mouthwash or not knowing about it, and parents/guardians with regular to high levels of knowledge about oral health and a regular or good/very good perception of their child's oral health. CONCLUSIONS: One in two children in the study had experienced dental pain in the twelve months prior to the survey. The association of socioeconomic variables with dental pain suggested inequalities among the children in terms of oral health.

RESUMO

Dental demineralization was determined in patients at three time points during fixed orthodontic treatment. A multiple cross-sectional study included 108 patients divided into three different groups: (1) beginning of orthodontic treatment; (2) one year into treatment; and (3) two years into treatment. Demineralization was estimated using a DIAGNOdent pen. We obtained data from multiple tooth-by-tooth demineralization readings combined with salivary pH and patients' oral hygienic and dietary behaviors. A t-test for independent samples and Spearman´s correlation were performed. No demineralizations differences were found between the initial stage and one year into treatment. Between one and two years small differences were observed, but demineralization increased between the initial stage and second treatment year, predominating in upper right central incisors (p = 0.056), upper left lateral incisors (p = 0.040), both upper canines (p = 0.055 and p = 0.040, respectively) and first left premolars (p = 0.034 and p = 0.053, respectively). We did not find associations between oral hygiene and dietary behaviours or salivary pH. In conclusion, demineralization occurred in first year of treatment and increased during second year, predominating in the upper arch and the left side mainly in upper right central incisors, upper left lateral incisors, both upper canines, and first left premolars.

RESUMO

OBJECTIVE: To determine the prevalence and the existence of socioeconomic inequalities in dental health service utilization (DHSU) any time in the life of Mexican schoolchildren aged 6-12 years of Pachuca Hidalgo, Mexico. MATERIAL AND METHODS: We performed a cross-sectional study in 1,404 school children 6-12 years of age from 14 public schools in the city of Pachuca, Hidalgo, Mexico. Questionnaires were distributed to determine socioeconomic position variables (SEP). The dependent variable was DHSU once in life (0 = No, 1 = Yes). The analysis was performed in Stata 9 using chi-square tests. RESULTS: The mean age was 8.97 ± 1.99 years, 50.1% were boys. The prevalence of DHSU any time in life was 71.4%. The DHSU percentage increased according increasing age (p < 0.05). Significant differences (p < 0.05) in percentages of USSB through SEP variables: health insurance, car ownership in the home, dwelling and household characteristics, a better level of SEP increased prevalence of DHSU. Although in the mother's schooling no differences were observed (p > 0.05), father's schooling was associated (p < 0.05) inversely to expectations. CONCLUSIONS: The findings of this study demonstrate that the prevalence of DHSU was not 100%; 28.6% of children have never had contact with a dentist. We identified certain indicator variables of SEP associated with DHSU, indicating the existence of inequalities in this oral health indicator.

RESUMO

El maltrato infantil es una patología de la cual se tienen registros desde las civilizaciones antiguas como la griega y egipcia; pero es hasta 1924 que se firma la declaración de Ginebra: Derechos de la infancia, siendo el IX derecho: No al Maltrato. En México se tiene registro de maltrato infantil desde hace 20 años. Se ha tipificado el maltrato infantil en dos grandes rubros: activo y pasivo, la negligencia odontológica es clasificado como maltrato pasivo, por lo tanto el odontólogo (en especial el Odontopediatra) debe prestar atención al hacer la inspección clínica y elaboración de historia clínica del paciente, para encontrar indicios de maltrato infantil y llevar a cabo la atención de estos pacientes con adecuado manejo de su conducta, la cual puede ser variable dependiendo el tipo de maltrato que ha sufrido. Las consecuencias del maltrato en cavidad oral son múltiples y pueden manifestarse a corto, largo y mediano plazo. En este artículo se presenta un caso clínico de maltrato por abandono, negligencia odontológica y las consecuencias que éste tuvo en la salud oral y general de la paciente.


Child abuse is a disease for which there are records from ancient civilizations like the Greek and Egyptian, but until 1924 when the Geneva Declaration was signed: Children's rights: No to Abuse. In Mexico records of child abuse have been kept for the last 20 years. It has classified child abuse into two major categories: active and passive, dental malpractice liability is classified as child abuse therefore the dentist (especially the pediatric dentist) should pay attention to realize a clinical inspection and preparation of patient history, for signs of child abuse, and carry out the care of these patients with adequate management of their behavior, which can vary depending on the type of abuse the child has suffered. The consequences of abuse in oral cavity are multiple and can occur at short, medium and long term. This article presents a case of abuse by dental neglect and the consequences that this has on oral health, and therefore on the general health of the patient.

RESUMO

The objective of this study is to determine the impact of socio-demographic, socioeconomic, and other risk indicators on dental fluorosis (DF) among Mexican adolescents. A cross-sectional study was carried out in 1,538 adolescents 12 and 15 years of age in semi-rural communities located at high altitude (>2,000 m) and with high concentration of fluoride in water (1.38-3.07 ppm) in Hidalgo, Mexico. DF was determined by means of Dean's Index and all teeth were examined. Remaining variables were collected using a questionnaire. The adjusted final model was performed using ordered logistic regression. After adjusting for sex, the variables associated with DF were (p < 0.05): being 12 years old (OR = 1.10) versus 15 years old; having lived the first 6 years of life in El Llano (3.07 F ppm) (OR = 3.19) or San Marcos (1.38 F ppm) (OR = 1.63) versus Tula (1.42 F ppm); having public (OR = 1.35) or private health insurance (OR = 1.36) versus those without insurance; belonging to the lower quartiles of socioeconomic position (SEP) [1st quartile (OR = 2.48), 2nd quartile (OR = 1.81), 3rd quartile (OR = 1.49)] versus the highest quartile; having drunk tap water (OR = 1.83) or from a well or spring (OR = 2.30) versus those who drank water purchased in large containers or bottles. Demographic and socioeconomic variables were associated with DF. While better SEP appeared to play an important role in DF, a pattern of water intake associated with water purchased in large containers or bottles (which have different connotations to the use of bottled water in industrialized Western countries) did reduce DF risk in these high fluoride content, high altitude communities.

RESUMO

OBJECTIVE: To determine the experience, prevalence and severity of dental caries and its relationship with nutritional status in nursery infants 17 to 47 months of age. MATERIAL AND METHODS: A cross-sectional study in 152 infants 17 to 47 months of age attending one of five day care centers of the city of Pachuca, Hidalgo was performed. Clinical examinations were performed using the methods recommended by the World Health Organization for epidemiologic studies on dental caries. We calculated the caries index (dmft), the significant caries index (SiC) as well as the treatment needs index (TNI) and the care index (CI). Nutritional status was determined using the weight and height for age, in Federico Gomez's scale. In the statistical analysis nonparametric tests were used. RESULTS: Mean age was 2.52 ± 0.76 years; 51.3% were boys. With regard to nutritional status, 19.1% were classified as malnourished and 19.1% were overweight/obese. The dmft index was 1.53 ± 2.52. The SiC index was 4.14, the TNI 86.3% and the CI 13.7%. Caries prevalence was 48.0%. It was observed that 33.5% of children had 1 to 3 teeth with caries experience and 14.5% had 4 or more teeth affected. Statistically significant differences for tooth decay were identified (p < 0.05) by age, height and weight but not (p> 0.05) by sex and nutritional status. CONCLUSIONS: This study shows that nearly half of children examined had caries experience. High treatment needs for dental caries were observed. A correlation was found between dmft index and age, weight and height. No association was identified between experience, prevalence and severity of dental caries and nutritional status of infants. It appears necessary to improve oral health preventive measures in these infants.
