          Objetivo: Determinar la gravedad de caries (tamaño de la lesión) y las variables asociadas en niños escolares mexicanos. Materiales y Métodos: Se realizó un estudio transversal en 1373 escolares de 6 a 12 años de edad inscritos en escuelas públicas de Campeche, México. Se distribuyeron cuestionarios para determinar una serie de variables sociodemográficas, socioeconómicas y conductuales. Se realizó un examen bucal a cada niño para establecer el tamaño de las lesiones de caries de acuerdo al índice llamado "criterio de magnitud de la lesión cariosa" y asignarlo de acuerdo al número de lesiones presentes a uno de 4 grupos de riesgo para desarrollar caries, en donde el primer grupo representa a los menos afectados. Se generó un modelo multivariado de regresión logística multinomial. Resultados: Los grupos de riesgo a caries quedaron distribuidos de la siguiente manera: 598 (43.6%) fueron del grupo 1; 261 (19.0%) se asignaron al grupo 2; 316 (23.0%) estuvieron en el grupo 3; y 198 (14.4%) en el grupo 4. Comparando con el grupo menos afectado por lesiones cariosas, las variables asociadas en los diferentes grupos de gravedad en el modelo multivariado fueron: grupo de riesgo 2: edad, sexo y defectos de desarrollo del esmalte; grupo de riesgo 3: atención dental en el último año, actitud de la madre hacia la salud bucal y defectos de desarrollo del esmalte; grupo de riesgo 4: edad, atención dental en el último año, actitud de la madre hacia la salud bucal y defectos de desarrollo del esmalte. Conclusión: La gravedad de caries está influenciada por variables demográficas, conductuales y clínicas.

          Objective: To determine the severity of caries (lesion size) and associated variables in Mexican schoolchildren. Material and Methods: A cross-sectional study was conducted in 1373 schoolchildren 6-12 years old enrolled in public schools in Campeche, Mexico. Questionnaires were distributed to determine demographic, socioeconomic and behavioral variables. Dental examination was performed to each child to establish the size of caries lesions according "Criterion of carious lesion magnitude" index and to allocate according to the number of lesions present to one of four risk groups for developing cavities wherein the first group represents the least affected. A multivariate multinomial logistic regression model was generated. Results: Caries risk groups were distributed as follows: 598 (43.6%) were in group 1; 261 (19.0%) were assigned to group 2; 316 (23.0%) were in group 3; and 198 (14.4%) in group 4. Comparing with the least affected group by carious lesions, associated variables for severity in the multivariate model were "Risk Group 2": age, sex and developmental enamel defects; "Risk Group 3": dental care in the past year, mother's attitude toward oral health and developmental enamel defects; "Risk Group 4": age, dental care in the past year, mother's attitude toward oral health and developmental enamel defects. Conclusion: Severity of decay is influenced by demographic, behavioral and clinical variables.

          The global burden of oral diseases and risks to oral health

          This paper outlines the burden of oral diseases worldwide and describes the influence of major sociobehavioural risk factors in oral health. Despite great improvements in the oral health of populations in several countries, global problems still persist. The burden of oral disease is particularly high for the disadvantaged and poor population groups in both developing and developed countries. Oral diseases such as dental caries, periodontal disease, tooth loss, oral mucosal lesions and oropharyngeal cancers, human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS)-related oral disease and orodental trauma are major public health problems worldwide and poor oral health has a profound effect on general health and quality of life. The diversity in oral disease patterns and development trends across countries and regions reflects distinct risk profiles and the establishment of preventive oral health care programmes. The important role of sociobehavioural and environmental factors in oral health and disease has been shown in a large number of socioepidemiological surveys. In addition to poor living conditions, the major risk factors relate to unhealthy lifestyles (i.e. poor diet, nutrition and oral hygiene and use of tobacco and alcohol), and limited availability and accessibility of oral health services. Several oral diseases are linked to noncommunicable chronic diseases primarily because of common risk factors. Moreover, general diseases often have oral manifestations (e.g. diabetes or HIV/AIDS). Worldwide strengthening of public health programmes through the implementation of effective measures for the prevention of oral disease and promotion of oral health is urgently needed. The challenges of improving oral health are particularly great in developing countries.

            Sex differences in dental caries experience: clinical evidence, complex etiology.

            J R Lukacs (2011)
            A sex difference in oral health has been widely documented through time and across cultures. Women's oral health declines more rapidly than men's with the onset of agriculture and the associated rise in fertility. The magnitude of this disparity in oral health by sex increases during ontogeny: from childhood, to adolescence, and through the reproductive years. Representative studies of sex differences in caries, tooth loss, and periodontal disease are critically reviewed. Surveys conducted in Hungary, India, and in an isolated traditional Brazilian sample provide additional support for a significant sex bias in dental caries, especially in mature adults. Compounding hormonal and reproductive factors, the sex difference in oral health in India appears to involve social and religious causes such as son preference, ritual fasting, and dietary restrictions during pregnancy. Like the sex difference in caries, tooth loss in women is greater than in men and has been linked to caries and parity. Results of genome wide association studies have found caries susceptible and caries protective loci that influence variation in taste, saliva, and enamel proteins, affecting the oral environment and the micro-structure of enamel. Genetic variation, some of which is X-linked, may partly explain how sex differences in oral health originate. A primary, but neglected, factor in explaining the sex differential in oral health is the complex and synergistic changes associated with female sex hormones, pregnancy, and women's reproductive life history. Caries etiology is complex and impacts understanding of the sex difference in oral health. Both biological (genetics, hormones, and reproductive history) and anthropological (behavioral) factors such culture-based division of labor and gender-based dietary preferences play a role.
