Rural and Urban Disparities in Caries Prevalence in Children with Unmet Dental Needs: The New England Children's Amalgam Trial

JOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 1 2008
Nancy Nairi Maserejian ScD
Abstract Objectives: To compare the prevalence of caries between rural and urban children with unmet dental health needs who participated in the New England Children's Amalgam Trial. Methods: Baseline tooth and surface caries were clinically assessed in children from rural Maine (n = 243) and urban Boston (n = 291), who were aged 6 to 10 years, with two or more posterior carious teeth and no previous amalgam restorations. Statistical analyses used negative binomial models for primary dentition caries and zero-inflated models for permanent dentition caries. Results: Urban children had a higher mean number of carious primary surfaces (8.5 versus 7.4) and teeth (4.5 versus 3.9) than rural children. The difference remained statistically significant after adjusting for sociodemographic factors and toothbrushing frequency. In permanent dentition, urban children were approximately three times as likely to have any carious surfaces or teeth. However, rural/urban dwelling was not statistically significant in the linear analysis of caries prevalence among children with any permanent dentition caries. Covariates that were statistically significant in all models were age and number of teeth. Toothbrushing frequency was also important for permanent teeth. Conclusions: Within this population of New England children with unmet oral health needs, significant differences were apparent between rural and urban children in the extent of untreated dental decay. Results indicate that families who agree to participate in programs offering reduced cost or free dental care may present with varying amounts of dental need based on geographic location. [source]

The relationship between the levels of SigA, lactoferrin and ,1 proteinase inhibitor in saliva and permanent dentition caries in 15-year-olds

A group of 15-year-olds were clinically examined for general state of dentition and level of dental caries. Unstimulated whole saliva from the subjects was laboratory tested to determine the levels of lactoferrin, Secretory IgA (SIgA) and ,1 proteinase inhibitor. A significant relationship was found between the decayed surface index and the levels of lactoferrin, SIgA and ,1 proteinase inhibitor in the unstimulated saliva. The decayed surface index rose with increases in the levels of lactoferrin, SIgA and ,1 proteinase inhibitor, the relationship with ,1 proteinase inhibitor being strongest. [source]

Clinical detection of caries in the primary dentition with and without bitewing radiography

AUSTRALIAN DENTAL JOURNAL, Issue 1 2009
B Newman
Abstract Background:, Inadequate detection of caries in the primary dentition due to non-use of bitewing radiography is commonly encountered in paediatric practice. The present study investigated the increased benefits of using bitewing radiography in addition to the visual-tactile examination technique for detection of primary dentition caries in a non-fluoridated community, and determined the prevalence of "hidden" occlusal caries in the primary dentition. Methods:, Primary teeth were scored for caries at the restorative threshold using a visual-tactile technique followed by bitewing radiographic examination in a sample of 611 schoolchildren aged 6.4 ± 0.5 yrs to 12.1 ± 0.8 yrs residing in a non-fluoridated city. Results:, Overall, at the restorative threshold, the visual-tactile technique could detect 62 per cent of occlusal caries compared to 74 per cent for bitewing radiography (p < 0.001). The prevalence of "hidden" occlusal caries was 12 per cent. In contrast, for primary molar proximal surface caries, the visual-tactile technique could detect only 43 per cent of caries compared with 91 per cent for bitewing radiography (p < 0.001). Conclusions:, In the primary dentition, use of bitewing radiography increases the detection rate of proximal surface caries substantially. It is recommended that bitewing radiography be included as part of the routine examination of children with proximal surfaces that cannot be visualized. [source]

Caries risk factors in the permanent dentition of Tanzanian children: a cohort study (1997,2003)

Abstract Objective:, The aims of the cohort study were to study the association between permanent dentition caries and malnutrition and other risk factors or indicators in a group of children with little or no access to restorative and preventive dental care. Methods:, The study was conducted at two primary schools in Dar es Salaam, Tanzania in the period 1997,2003. One school recruits its children from affluent families and the other school is attended by the children of poor families. The children attended grade 1 at the first examination and had a mean age of 7.6 years (SD = 0.4); when the study was completed, the mean age was 13.3 years. Two-hundred and eighteen children examined in 1997 were re-examined in 1999; 147 of the children were examined in 1997 as well as in 2003, and 122 children were examined in all three years. An age- and sex-based body mass index (BMI) was computed to determine the nutritional status of each child. Each year, the same standard methods were used to determine the count of lactobacilli and mutans streptococci, stimulated flow rate and buffering capacity of saliva, and caries. Risk ratios were computed with generalized linear models using the tooth as the unit of analysis. Results:, Mean annual caries increment was 0.27 in the period 1997,1999 and 0.80 in the period 1999,2003 with most children developing no caries at all. Malnutrition at baseline in 1997 was insignificantly predictive for the development of caries, whereas a low stimulated flow rate of saliva (,0.7 ml/min) and a high count of lactobacilli (,100 000/ml) at baseline in 1997 were significantly associated. However, the generalized linear models for the two time periods 1997,1999 and 1999,2003 presented a confusing picture with different risk ratios and without consistency of the associations between the exposure variables and the development of caries. In accordance with this finding, the consistency of the exposure variables over time for the individuals was very low. Conclusions:, The results were inconclusive and left us with more questions than answers. The findings do, however, support the view that our methods for predicting caries are inappropriate or nonexistent. [source]
