Changes in oral pH before and after placing preformed metal crowns in primary dentition of Mexican children.

BACKGROUND: Prefabricated metal crowns (PMCs) have been widely used in pediatric dentistry due to their great success in various clinical situations. However, it is important to know the local effects, such as changes in pH in the oral environment. OBJECTIVE: To evaluate the pH variations before and after placement of PMCs. METHODS: A quasi-experimental study (before and after) was performed with 32 pediatric patients who needed rehabilitation with PMCs at a pediatric dentistry clinic in a public university. Measurements were made using a pH potentiometer before PMC placement, one week after, and one month after placement. ANOVA and Pearson correlation were performed in SPSS. RESULTS: The average age of the participants was 5.9 ± 1.6 years, and 53.1% were female. The average pH before, one week after, and one month after crown placement was 7.46 ± 0.37, 7.00 ± 0.32, and 7.1 ± 0.19, respectively. Significant differences (p< 0.05) were observed between the three pH measurements. We found differences when comparing the basal pH values to those at one week (p= 0.001) and one month (p= 0.002). CONCLUSION: Although there were statistically significant differences in the pH change values before and after the placement of crowns, these differences may not have a clinical impact.

Characterizing Socioeconomic Inequalities in Professionally Applied Topical Fluoride Treatment Courses in Schoolchildren from a Developing Country.

The objective of the present study was to characterize socioeconomic inequalities in the patterns of professionally applied topical fluoride (PATF) in Mexican schoolchildren. A cross-sectional study was carried out on 3029 Mexican schoolchildren. A questionnaire was administered to caregivers to determine sociodemographic, socioeconomic, and behavioral variables. The dependent variable was prevalence of PATF, coded as 0 = without PATF and 1 = with PATF, at any point in life, and separately, in the previous year. Various indicators of socioeconomic position were included. Logistic regression was used in the final multivariate analysis. The prevalence of PATF any time in life was 33.8%, while in the previous year it was 11.4%. The variables associated (p < 0.05) with PATF any time in life were child's older age (OR = 1.12), older age when tooth brushing started (OR = 1.57), higher brushing frequency (OR = 1.60), having health insurance [public (OR = 1.61) or private (OR = 1.45)], if family owned a car (OR = 1.29) and better socioeconomic position [parents' education, second (OR = 1.48) and third (OR = 1.75) tertile]. For PATF in the previous year, the variables associated were older age of mother (OR = 1.03), older age when tooth brushing started (OR = 1.99), higher brushing frequency (OR = 1.68), having health insurance [public (OR = 1.62)] and better socioeconomic position (parents' education, second (OR = 1.57) and third (OR = 1.97) tertile). This study suggests the existence of socioeconomic inequalities in PATF, manifested through socioeconomic position, access to health insurance and household having a car. Identifying and addressing PATF inequalities would improve oral health in the child population.

Dental pain prevalence associated with caries experience in pediatric patients in a clinical sample in Mexico.

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.

Self-reported oral hygiene practices with emphasis on frequency of tooth brushing: A cross-sectional study of Mexican older adults aged 60 years or above.

The objective of the study was to characterize self-reported oral hygiene practices among Mexican older adults aged ≥60 years, and to measure the association between frequency of tooth brushing and a set of sociodemographic, socioeconomic, and dental variables.We conducted a cross-sectional study of 139 older adults aged ≥60 years in Pachuca, Mexico. A questionnaire and a clinical dental examination were administered to identify specific variables. We determined frequency of tooth brushing (or cleaning of dentures or prostheses) and use of toothpaste, mouthwash, and dental floss among respondents. Non-parametric testing was performed for statistical analysis and a multivariate logistic regression model was generated with Stata 11 software to determine frequency of tooth brushing.In our study sample, 53.2% of participants reported brushing their teeth at least once a day, 50.4% always using toothpaste, 16.5% using mouthwash and 3.6% using floss for their oral hygiene. In general, younger and female respondents used oral hygiene aids more than the others. Our multivariate model yielded an association (P < .05) between tooth brushing at least once daily and the following variables: having functional dentition (OR = 12.60), lacking health insurance (OR = 3.72), being retired/pensioned (OR = 4.50), and suffering from a chronic disease (OR = 0.43).The older adults in our sample exhibited deficient oral hygiene behaviors. The results suggest certain socioeconomic inequalities in oral health. The findings of this study should be considered when designing dental care instructions for older adults.

Traumatismo dental en pacientes pediátricos que acuden a una clínica universitaria de odontopediatría: un análisis retrospectivo de historias clínicas

Objetivo: Determinar la prevalencia de traumatismos dentales en los pacientes que acuden a una clínica de Especialidad en Odontopediatría. Materiales y Métodos: Se realizó un estudio transversal retrolectivo, se incluyeron 309 expedientes clínicos de pacientes de 2 a 12 años de edad que acudieron para su atención a la clínica de la Especialidad de Odontopediatría de una universidad pública en Toluca, México. La variable dependiente fue la prevalencia de traumatismo dental. Las variables independientes incluidas en el estudio fueron: edad del paciente y sexo. El análisis estadístico se realizó utilizando pruebas no paramétricas en Stata 11. Resultados: El promedio de edad fue de 5.71±2.43 años y el 50.8% fueron hombres. La prevalencia de traumatismo dental previo al estudio fue de 12.0% (IC 95% = 8.3 - 15.6). En el análisis bivariado, a pesar de que los varones presentaron una prevalencia de traumatismo dental de 14.0% y entre las mujeres fue de 9.9%, estas diferencias no fueron estadísticamente significativas (p=0.262). Se observó que los niños con traumatismo dental fueron más pequeños (promedio de edad = 4.74±1.86) que los que no presentaron traumatismo dental (promedio de edad = 5.84±2.47) (p=0.0166). Al realizar la prueba de tendencia no paramétrica se notó que la disminución de la prevalencia de traumatismo dental fue significativa (p=0.026). Conclusiones: La prevalencia de traumatismo dental en esta muestra de niños fue de 12%. No se observó diferencia por sexo. Los más pequeños presentaron más traumatismo dental que los más grandes.

Objective: To determine the prevalence of dental trauma in patients who consulted at a pediatric dentistry specialty clinic. Materials and methods: This was a retrospective cross-sectional study in which we reviewed 309 clinical files of patients from 2 to 12 years of age who consulted at the Pediatric Specialty Dentistry at a public university in Toluca, Mexico. The dependent variable was the prevalence of dental trauma. The independent variables included in the study were: patient's age and sex. Statistical analysis was performed using nonparametric tests in Stata 11. Results: The average age was 5.71 ± 2.43 years and 50.8% were male. The prevalence of dental trauma was 12.0% (95% CI = 8.3 - 15.6). In the bivariate analysis, despite the fact that males had a prevalence of dental trauma of 14.0% and among women it was 9.9%, these differences were not statistically significant (p = 0.262). It was observed that children with dental trauma were younger (average age = 4.74 ± 1.86) than those who did not present dental trauma (average age = 5.84 ± 2.47) (p = 0.0166). When performing the non-parametric trend test, it was noted that the decrease in the prevalence of dental trauma was significant (p = 0.026). Conclusions: The prevalence of dental trauma in this sample of children was 12%. No difference was observed according to sex. Younger patients presented more dental trauma than older ones.

Difference between manual and digital measurements of dental arches of orthodontic patients.

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.

Manejo odontológico del paciente con hipoacusia neurosensorial profunda bilateral / Dental management of patients with bilateral profound sensorineural hearing loss

Introducción: la hipoacusia es la disminución de la agudeza auditiva o de la capacidad para captar el sonido; esta puede ser neurosensorial, conductiva o mixta. La hipoacusia neurosensorial resulta de alteraciones en el oído interno, nervio auditivo o en los núcleos auditivos del tronco cerebral. El manejo de estos pacientes requiere disposición, conocimientos y calidez para el correcto desarrollo de la atención estomatológica. Objetivo: reportar el manejo odontológico de un paciente con hipoacusia neurosensorial profunda bilateral. Presentación del caso: paciente femenino de 7 años y 10 meses de edad con diagnóstico de hipoacusia neurosensorial profunda bilateral, quien acude a consulta por presentar dolor. A la inspección física, paciente mesofacial, perfil convexo. Intraoralmente se observan tejidos blandos clínicamente sanos, alteraciones de número y posición, caries moderada e higiene deficiente. Durante la inspección clínica la paciente se mostró poco cooperadora (Frankl II). El plan de tratamiento consistió en prevención, operatoria, ortopedia y cirugía. Para el manejo del paciente se incluyó un lenguaje de señas básico con uso de careta y sin cubreboca, modelado con otros pacientes. Se modificó la técnica decir, mostrar y hacer por mostrar/oler, tocar y hacer. Conclusiones: el odontopediatra debe tener las competencias necesarias para la atención integral de pacientes con capacidades diferentes. El manejo de la conducta y el cuidado multidisciplinario del paciente en edades tempranas es fundamental para el éxito del tratamiento. En el caso clínico que se presenta se resalta la efectividad del manejo conductual modificado, lo cual incrementó la posibilidad de éxito de la rehabilitación dental del paciente, así como de su seguimiento(AU)

Introduction: hearing loss is reduced auditory acuity or a decrease in the ability to perceive sound. It may be sensorineural, conductive or mixed. Sensorineural hearing loss results from alterations in the inner ear, the auditory nerve or the auditory brainstem nuclei. Dental management of these patients requires willingness, knowledge and warmth on the part of the dental practitioner. Objective: report the dental management of a patient with bilateral profound sensorineural hearing loss. Case presentation: a female patient aged 7 years and 10 months diagnosed with bilateral profound sensorineural hearing loss attends consultation for dental pain. At physical inspection, it is observed that the patient is mesofacial with a convex profile. Intraoral examination found clinically healthy soft tissue, tooth alterations in number and position, moderate decay and poor hygiene. During clinical inspection, the patient was uncooperative (Frankl II). Treatment consisted in prevention, restoration, orthopedics and surgery. Management of the patient included use of basic sign language and a mask without the practitioner wearing a facemask, and modeling with other patients. The technique of say, show and do was replaced by show / smell, touch and do. Conclusions: pediatric dentists should have the skills required for the comprehensive care of patients with different capabilities. Behavior management and multidisciplinary care of very young patients is essential for a successful treatment. The clinical case herein presented highlights the effectiveness of modified behavior management, which increased the chances of success in the patient's dental rehabilitation and follow-up(AU)

[Socioeconomic inequalities in oral health service utilization any time in their lives for Mexican schoolchildren from 6 to 12 years old]. / Desigualdades socioeconómicas en la utilización de servicios de salud bucal (USSB) alguna vez en la vida por escolares Mexicanos de 6-12 años de edad.

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.
