Item Dental pain prevalence associated with caries experience in pediatric patients in a clinical sample in Mexico(Sociedade Brasileira de Pesquisa Odontológica(SBPqO), 2021) Hernandez-Martinez, Cesar Tadeo; Jimenez-Gayosso, Sandra Isabel; Lucas-Rincon, Salvador Eduardo; Robles-Bermeo, Norma Leticia; Maupome, GerardoThe 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.Item Detección de Ni, Fe y Cr liberados en la saliva después de la colocación de coronas metálicas prefabricadas en niños(Universidad Autónoma de Campeche, 2023) Jiménez-Gayosso, Sandra Isabel; Morales-Luckie, Raúl Alberto; Robles-Bermeo, Norma Leticia; Hernández-Martínez, César Tadeo; Ramírez-Cardona, Marius; Pontigo-Loyola, América Patricia; Sosa-Velasco, Taurino Amílcar; García-Hernández, Verónica; Medina-Solís, Carlo Eduardo; Maupomé, GerardoObjetivo: Detectar la presencia y concentración de hierro (Fe), cromo (Cr) y níquel (Ni) en saliva de pacientes que requieren rehabilitación con coronas metálicas prefabricadas (CMP), antes y después de su colocación. Material y Métodos: Se realizó un estudio cuasi-experimental (antes-después) en 32 pacientes que asistieron a atención odontológica en una clínica de odontopediatría de una universidad pública y que requirieron rehabilitación con CMP. Se tomaron muestras de 5 ml de saliva no estimulada por paciente de acuerdo con las pautas estandarizadas. La primera muestra se tomó antes de la rehabilitación de los CMP, y las otras dos se tomaron 1 semana y 1 mes después de la colocación de los PMC. Los niveles de metal se midieron mediante espectrometría de emisión óptica de plasma acoplado inductivamente (ICP-OES). Se realizaron pruebas paramétricas (ANOVA y correlación de Pearson), y se consideró estadísticamente significativa una p<0,05. Resultados: La edad media fue de 5.71±1.72 años y el 53.1% eran mujeres. Se encontraron diferencias estadísticamente significativas al comparar la liberación de Ni antes, 1 semana y 1 mes después de colocar las coronas. De manera similar, observamos una correlación positiva entre el número de coronas y la liberación de Ni. Las cantidades de Fe y Cr fueron inferiores a 0,1 ppb, lo que no fue detectable por ICP-OES. Hubo una ligera correlación negativa entre el número de coronas y los valores basales de Ni (r = −0.342, p = 0.056). Conclusión: Se observaron cambios, antes y después de colocar las PMC, en los niveles de Ni. Los niveles de Fe y Cr fueron inferiores a 0,1 ppb, por lo que no fueron evaluables. Los niveles de Fe, Cr y Ni liberados estaban por debajo de los niveles tóxicos para la salud.Item Experience, Prevalence, Need for Treatment and Cost of Care for Caries: A Multicenter Study in a Developing Country(FDI World Dental Press Ltd., 2022-05-27) Lucas-Rincón, Salvador E.; Lara-Carrillo, Edith; Robles-Bermeo, Norma Leticia; Rueda-Ibarra, Vicente; Alonso-Sánchez, Carmen C.; Vázquez-Rodríguez, Sandra B.; Ávila-Burgos, Leticia; Medina-Solis, Carlo E.; Maupomé, GerardoObjective: To assess the experience, prevalence, need for treatment and economic impact of caries among students 6-12 years old in four cities in Mexico. Basic research design: Cross-sectional clinical study. Setting: Elementary public schools. Participants: 500 schoolchildren aged 6 to 12 years. Method: Oral clinical examinations using WHO criteria for caries in the primary (dmft) and permanent (DMFT) dentitions. Main outcome measures: Indicators of caries in the primary and permanent dentitions: experience, prevalence, severity and the Significant Caries Index. In addition, we calculated the treatment needs, dental care rate and cost of care. Results: dmft in the primary dentition was 2.59±2.83, and DMFT was 0.82±1.44 in the permanent dentition. Caries prevalence reached 67.7% in the primary and 34.1% in permanent dentition. The treatment needs index was 85.9% and 91.3% in the primary and permanent dentitions, respectively; the dental care index was 13.9% and 8.5%, respectively. The cost of care for caries in the primary dentition was estimated at $22.087 millions of international dollars (PPP US$) when amalgam was the restorative material used, and PPP US$19.107 millions for glass ionomer. For the permanent dentition, the cost was PPP US$7.431 millions when amalgam was used and PPP US$7.985 millions when resin/composite was used as restorative material. Conclusions: The prevalence and experience of caries in the primary dentition were 50% greater than those of other studies carried out in Mexico. In the permanent dentition they were less. There is considerable need for the treatment of caries and minimal experience with restorative care. The cost of care for caries may be assumed to be high for a health system such as Mexico's.Item Experiencia, prevalencia y severidad de caries dental asociada con el estado nutricional en infantes mexicanos de 17 a 47 meses de edad(2013) Zúñiga-Manríquez, Ana Gabriela; Medina-Solís, Carlo Eduardo; Lara-Carrillo, Edith; de Lourdes Márquez-Corona, María; Robles-Bermeo, Norma Leticia; Scougall-Vilchis, Rogelio José; Maupomé, GerardoObjective. 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.
