Dental caries and associated factors in Mexican schoolchildren aged 6–13 years

Abstract

The objectives of the present study were to establish dental caries prevalence (percentage with caries) and experience in the primary and permanent dentition (dmft and DMFT) of 6 to 13-year-old schoolchildren in Campeche, Mexico, and to estimate the contributing roles of the likely risk indicators. A cross-sectional study was carried out in 1,644 children aged 6-13 years. Self-administered questionnaires obtained information on social, economic, behavioral, and demographic variables. The primary dentition of 1,309 children and the permanent dentition of 1,640 children were evaluated in the oral examinations. The main outcome measures were DMFT, dmft, and SiC indices. Data were modeled using logistic regression analysis. The overall caries prevalence was 77.4%, 73.6% in the primary dentition (61.6% in 6-year-olds), and 49.4% in the permanent dentition. The dmft and DMFT indices were 2.85+/-2.73 and 1.44+/-2.05, respectively (DMFT = 3.11+/-2.62 in 12-year-olds). The SiC index was 6.05 at 12 years of age. Associated variables to dental caries in both dentitions were presence of enamel defects, presence of dental plaque, low socio-economic status, female sex, and older age. Mother's schooling was negatively associated (OR = 0.95) with caries in primary dentition. Caries experience in the primary dentition (OR = 6.02) was positively associated with caries in the permanent dentition. Dental caries status in these Mexican children was closer to the goals proposed by the WHO/FDI for 2000 than previous studies. This study has identified clinical, socio-economic, and behavioral determinants for dental caries in primary and permanent dentition on Mexican schoolchildren.

The Associated Factors of Permanent First Molar Caries in 7-9 Years Old Children

“…There was a significant relationship between dmft and the first permanent molar caries. It is simil-lar to the findings of Rosado et al (7) and Raadal et al (9) Li et al showed that children having caries in their primary teeth were three times more likely to develop caries in their permanent teeth. (10) According to the definition of dental caries as an infectious disease that can spread to other teeth, increasing the number of dental caries in primary teeth, raises the risk of caries in the permanent teeth.…”

“…Caries experience in the primary dentition was positively associated with caries in the permanent dentition. (7) According to J. Vanobbergen et al none of the socio-demographic and behavioral variables had enough predictive power at community level to be useful in identifying caries susceptible children. (8) The aim of this study was to find whether dmft, oral hygiene and dietary habits of children with caries in permanent first molars are different from those with healthy first molars?…”

Association between socioeconomic status and oral health behaviors: The 2008–2010 Korea national health and nutrition examination survey

“…Individuals with low education levels, defined as less than a high school degree, had a higher prevalence of tooth loss in a previous study (29). Similarly, in young children, the prevalence of tooth brushing was higher among the children of mothers with higher education, as compared with those born to mothers with a lower education (32). Furthermore, it has been demonstrated that the type of school (middle or high) and school grade may affect the oral health behavior of adolescents (24).…”

Caries dental en escolares de 6 a 12 añios de edad en Navolato, Sinaloa, México: experiencia, prevalencia, gravedad y necesidades de tratamiento.

“…Sin embargo, en ellos no se midieron de la misma forma las lesiones de caries. Igualmente, es inevitable resaltar la baja presencia de dientes restaurados (< 10% de los índices ceod/CPOD), común en países en vías de desarrollo (6,(30)(31)(32), lo que de una manera u otra refleja o podría estar reflejando, por un lado, la nula importancia que tiene la salud bucal en la población, en este caso entre las madres/tutores de los niños, al igual que la observada en otras poblaciones mexicanas (33) y, por otro lado, el acceso que tienen los individuos a los servicios tanto curativos como de promoción de la salud bucal. Sin embargo, es necesario destacar que en la dentición primaria las lesiones no cavitadas representaron menos de 40% del componente "dientes cariados", pero en la dentición permanente se observaron resultados distintos; las lesiones no cavitadas fueron el mayor porcentaje de ese componente (> 60%).…”

“…En 1997 en Campeche, Casanova y cols. reportaron por su parte un promedio de más de tres dientes afectados y una prevalencia de poco más de 80% en la dentición permanente de los niños de 12 años de edad (6). En ese mismo estado y año, Vallejos y cols.…”
