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.

The aim of this cross-sectional study was to evaluate the association between socioeconomic indicators and use of dental services in a sample of 3,048 Mexican schoolchildren. The dependent variable "use of dental services" and independent variables were collected through a questionnaire addressed to mothers. To determine oral health needs, a clinical oral examination was performed. The adjusted associations were evaluated using polytomous logistic regression. Adjusted by gender, the categories associated with both preventive and curative services were age, greater frequency of brushing, earlier initiation of brushing, healthcare coverage, and better socioeconomic status. In addition, for preventive services only, use of services was associated with enrolment in private school, and for curative services only, family's possession of an automobile and having moderate to high oral health needs. The results suggest the existence of socioeconomic inequalities in the use of both preventive and curative dental services by Mexican children.

El objetivo del estudio fue evaluar la asociación entre diversos indicadores socioeconómicos y la utilización de servicios de salud bucal. Se realizó un estudio transversal en 3.048 escolares. La variable utilización de servicios de salud bucal y las variables sociodemográficas y socioeconómicas se colectaron a través de un cuestionario dirigido a las madres. Para determinar las necesidades de salud se realizó un examen clínico bucal a los niños. Las asociaciones ajustadas fueron evaluadas con regresión logística politómica. Las variables asociadas a servicios preventivos y curativos fueron mayor edad, mayor frecuencia de cepillado y menor edad al inicio de cepillado dental, tener seguro público o privado, y mejor nivel socioeconómico. Además, sólo para los servicios preventivos, también se asoció estar inscrito en una escuela privada, y sólo para los servicios curativos, la posesión de automóvil y tener necesidades de salud bucal entre moderadas y muy altas. Los resultados sugieren la existencia de desigualdades socioeconómicas en la utilización de servicios de salud bucal en niños mexicanos.

Introducción. La caries dental es una de las enfermedades más prevalentes en los niños. Objetivo. Determinar la experiencia, prevalencia y gravedad de caries en la dentición temporal y permanente; establecer igualmente el índice de caries significativa (SiC, por sus siglas en inglés), en escolares de Navolato, Sinaloa, México, así como sus necesidades de tratamiento. Materiales y métodos. Se realizó un estudio transversal en 3.048 niños de 6 a 12 años de edad. Los sujetos fueron examinados clínicamente por tres examinadores (índice k > 0,85), de acuerdo a los lineamientos establecidos por la Organización Mundial de la Salud (OMS). Para la detección de caries se empleó el criterio de la OMS y la lesión d1 de Pitts. Resultados. La media de edad fue de 8,81±1,79 años y el porcentaje de niñas fue de 52,2%. En la dentición temporal, el ceod (Promedio de dientes cariados, extraídos/perdidos y obturados) fue de 4,68±3,21 y la prevalencia de caries 90,2% (ceod > 3 = 60,8%). El índice significativo de caries fue de 10,52 para los niños de seis años de edad. Las lesiones no cavitadas (d1) representaron 37,1% del componente "cariados". En la dentición permanente, el índice CPOD (Promedio de dientes permanentes cariados, perdidos y obturados) fue de 3,24±2,72 y la prevalencia de caries, 82% (CPOD > 3 = 47,8%). El índice de caries significativa fue de 10,87 para los niños de 12 años. Las lesiones no cavitadas representaron 63,4% del componente "cariados". Al menos 81,1% de los niños necesitó la restauración de una superficie dental y 89,6%, de dos. Las niñas presentaron más caries que los niños en su dentición permanente. Se observó que conforme aumentó la edad se incrementó la experiencia de caries. Conclusiones. Se observaron altos índices de caries, así como alta prevalencia, gravedad y necesidad de tratamiento. Las lesiones no cavitadas constituyeron el principal porcentaje en la dentición permanente, no así en la dentición temporal.

Introduction. Dental caries is the most prevalent disease in children. Objective. To determine the caries experience, prevalence, and severity in temporal and permanent dentition, likewise to establish the significant caries index in schoolchildren of Navolato, Sinaloa, Mexico as well as their treatment needs. Material and methods. A cross sectional study in 3048 schoolchildren aged 6 to 12 years. All subjects were clinically examined by three examiners (kappa>0.85), according to World Health Organization (WHO) guidelines. Caries detection criteria used were the WHO’s criteria and Pitts’ lesion d1. Results. The mean age was 8.81±1.79 years old and 52.2% were girls. In the temporal dentition; the dmft was 4.68±3.21 and caries prevalence of 90.2% (dmft>3 was 60.8%, and dmft>6 was 27.4%). The overall significant caries index was 10.52 for 6 year olds. The noncavitated lesions (d1) represented 37.1% of the "decay" component. In the permanent dentition; the DMFT was 3.24±2.72 and caries prevalence was 82.0% (DMFT>3 was 47.8%, and DMFT>6 was 9.0%). The overall significant caries index was 10.87 for 12 year olds. The noncavitated lesions (d1) represented 63.4% of the "decay" component. The majority, 89.6% and 81.1% of children needed at least one restoration of one and two dental surfaces, respectively. Girls were more affected by caries than boys in permanent dentition, but not in temporal dentition. The caries experience increased with age. Conclusions. We observed high indices of caries, and high prevalence, severity and treatment needs. Noncavitated lesions were higher in permanent dentition that in primary dentition.
