Caries status and overweight in 2‐ to 18‐year‐old US children: findings from national surveys

BACKGROUND The prevalence of overweight children in the United States continues to increase. OBJECTIVES To examine the relationship between being overweight and caries in primary and permanent dentition in a nationally representative sample of children. METHODS Data from the NHANES III (1988-1994) were analyzed using logistic regression and controlling for potential confounders for 10 180 children 2-18 years of age and from the NHANES 1999-2002 for 7568 children 2-18 years of age. RESULTS For children 2-5 years of age, there was no difference in caries experience among normal weight, at risk for overweight or overweight children for NHANES III and for NHANES 1999-2002. For children 6-11 years of age (NHANES III), at risk for overweight and overweight children were less likely to have caries experience in the primary dentition than normal weight children; overweight children were less likely to have caries experience in the permanent dentition than normal weight children. For children 12-18 years of age (NHANES III), overweight children were less likely to have caries experience in the permanent dentition than normal weight children. For children 6-11 years of age and 12-18 years of age (NHANES 1999-2002), there was no difference in having caries experience among normal, at risk for overweight and overweight children. CONCLUSIONS The data from NHANES III and NHANES 1999-2002 provide no evidence to suggest that overweight children are at an increased risk for dental caries. Although no differences in caries rates by weight were found in younger children, interestingly results from NHANES III suggest that being overweight may be associated with decreased rates of caries in older children.

Teledentistry in inner-city child-care centres

In Rochester, NY, telehealth centres were established in six inner-city elementary schools and seven child-care centres. The teledentistry project complemented the existing telehealth model. Using an intraoral camera, telehealth assistants record digital images of childrens teeth (768 × 494 pixels) and send the images to a computer at the expert dental site (the Eastman Department of Dentistry at the University of Rochester). The paediatric dentist at the expert site reviews the images, and provides referral and treatment recommendations. Subsequently, the telehealth assistant contacts the childs parents or guardians and assists them to obtain appropriate dental care for their child. In the pilot study, we screened 50 children. In the first nine months of 2005, we screened 123 children. The results of our initial teledental screenings of children aged 12–48 months attending inner-city child-care centres revealed that almost 40% had active dental caries, mainly early childhood caries (ECC). For the first time, many children attending inner-city child-care centres have had their teeth examined at an early age and been given prompt feedback on the need for dental care.

Effect of Tobacco Smoke on the Oral Health of US Women of Childbearing Age

OBJECTIVES To determine the oral health status of US women of childbearing age and to analyze the effect of tobacco smoke on their oral health. METHODS Data from the 1999-2004 National Health and Nutrition Examination Survey were evaluated for women 15-44 years of age. The association of exposure to tobacco smoke with untreated caries, mean DMFS, gingivitis, and periodontitis were examined in bivariate and regression analyses controlling for potential confounders. RESULTS The prevalence of untreated caries was 25%, for gingivitis 49%, and for periodontitis 6%. After adjusting for potential confounders, self-reported current smoking was a strong independent risk indicator for untreated caries, periodontitis, and to a lesser extent for greater DMFS count. Women with detectable cotinine levels below 15 ng/mL presented with an increased risk for gingivitis. Independent factors associated with increased risk for untreated caries were being Black, having less than a high school education, Medicaid or no health insurance, previous live births, and infrequent and episodic dental visits. Characteristics associated with gingivitis were being Mexican-American, obese, pregnant, and having infrequent dental visits. Older age, no insurance, and the last dental visit for treatment were independently associated with periodontitis. CONCLUSIONS Dental caries and periodontitis were prevalent among certain subgroups of women of reproductive age. Smoking was found to be a significant risk indicator for various negative oral health outcomes. Barriers to accessing to dental care that were manifested by untreated caries among Black women, mothers, and Medicaid beneficiaries must be better understood.

Prevalence of dental caries and dental care utilisation in preschool urban children enrolled in a comparative-effectiveness study

AIM: To assess dental caries prevalence and dental care utilisation in pre-school children enrolled in urban childcare centres that participated in a comparative-effectiveness study. STUDY DESIGN: Cross-sectional study. METHODS: Caries prevalence was determined in a cohort of children 12–60 months of age. Eligible children were randomised into two groups: group one received a traditional visual/tactile oral examination and group two received a teledentistry examination. Questionnaires were administered to the children’s parents/guardians to gather demographics and information about using dental and medical services. RESULTS: Of 234 children examined, approximately 28% had caries experience. The mean dfs score was 1.56 with a range of 0–34 carious surfaces. The mean dfs score for the children examined by means of teledentistry was 1.75 and for the children examined by means of the traditional visual/tactile method mean dfs was 1.40; the means between the two groups were not significantly different. Twenty-six children showed evidence of being treated for dental caries. According to the parents, 31.5% of the children had never had a dental check-up before, only 3% of the children were lacking dental insurance and majority of the parents (92%) did not perceive accessing dental care for the children as a problem. STATISTICS: The Wilcoxon Mann-Whitney test and the Kruskal-Wallis test were used to assess statistical differences among groups of children. CONCLUSIONS: The data showed that 28% of the children had caries and, of these, 61% had never been treated for caries, thus indicating that continued efforts are needed to improve oral health care utilisation by inner-city preschool children.

Candida albicans Carriage in Children with Severe Early Childhood Caries (S-ECC) and Maternal Relatedness.

Introduction Candida albicans has been detected together with Streptococcus mutans in high numbers in plaque-biofilm from children with early childhood caries (ECC). The goal of this study was to examine the C. albicans carriage in children with severe early childhood caries (S-ECC) and the maternal relatedness. Methods Subjects in this pilot cross-sectional study were recruited based on a convenient sample. DMFT(S)/dmft(s) caries and plaque scores were assessed during a comprehensive oral exam. Social-demographic and related background information was collected through a questionnaire. Saliva and plaque sample from all children and mother subjects were collected. C. albicans were isolated by BBL™ CHROMagar™ and also identified using germ tube test. S. mutans was isolated using Mitis Salivarius with Bacitracin selective medium and identified by colony morphology. Genetic relatedness was examined using restriction endonuclease analysis of the C. albicans genome using BssHII (REAG-B). Multilocus sequence typing was used to examine the clustering information of isolated C. albicans. Spot assay was performed to examine the C. albicans Caspofungin susceptibility between S-ECC children and their mothers. All statistical analyses (power analysis for sample size, Spearman’s correlation coefficient and multiple regression analyses) were implemented with SAS 9.4 Results A total of 18 S-ECC child-mother pairs and 17 caries free child-mother pairs were enrolled in the study. Results indicated high C. albicans carriage rate in the oral cavity (saliva and plaque) of both S-ECC children and their mothers (>80%). Spearman’s correlation coefficient also indicated a significant correlation between salivary and plaque C. albicans and S. mutans carriage (p<0.01) and caries severity (p<0.05). The levels of C. albicans in the prepared saliva and plaque sample (1ml resuspension) of S-ECC children were 1.3 ± 4.5 x104 cfu/ml and 1.2 ± 3.5 x104 cfu/ml (~3-log higher vs. caries-free children). Among 18 child-mother pairs, >60% of them demonstrated identical C. albicans REAG-B pattern. C. albicans isolated from >65% of child-mother pairs demonstrated similar susceptibility to caspofungin in spot assay, while no caspofungin resistant strains were seen when compared with C. albicans wild-type strain SC5314. Interestingly, the regression analysis showed that factors such as antibiotic usage, birth weight, inhaler use, brushing frequency, and daycare attendance had no significant effect on the oral carriage of C. albicans in the S-ECC children. Conclusions Our results reveal that both the child with S-ECC and the mother were highly infected with C. albicans, while most of the strains were genetically related, suggesting that the mother might be a source for C. albicans acquisition in the oral cavity of children affected by the disease.

Comparative Effectiveness Study to Assess Two Examination Modalities Used to Detect Dental Caries in Preschool Urban Children

BACKGROUND Dental caries affecting the primary dentition of U.S. children continues to be the most prevalent chronic childhood disease. Preventive screening for dental caries in toddlers by dental professionals is labor-intensive and costly. Studies are warranted to examine innovative screening modalities that reduce cost, are less labor-intensive, and have the potential to identify caries in high-risk children. SUBJECTS AND METHODS Two hundred ninety-one children were randomized into two groups: Group 1 received a traditional, visual tactile examination initially and follow up-examinations at 6 and 12 months, and Group 2 received a teledentistry examination initially and follow-up examinations at 6 and 12 months. The mean primary tooth decayed and filled surfaces (dfs) scores were calculated for all children at baseline and 6 and 12 months. RESULTS At baseline, the mean dfs score for children examined by means of teledentistry was 2.19, and for the children examined by means of the traditional method, the mean was 1.27; the means were not significantly different. At the 12-month examination, the mean dfs score for the children examined by means of teledentistry was 3.02, and for the children examined by means of the clinical method, the mean dfs was 1.70; the means were not significantly different. At 12 months the mean fillings score for the children examined by means of teledentistry was 1.43 and for the children examined by means of the clinical method was 0.51; the means were statistically significantly different (p<0.001). CONCLUSIONS These results suggest that the teledentistry examinations were comparable to clinical examinations when screening for early childhood caries in preschool children. The data further showed that color printouts of teeth with cavities provided to parents of children who received teledentistry screenings promoted oral healthcare utilization, as children from the teledentistry study group received more dental care than children from the clinical study group.

Candida albicans and Early Childhood Caries: A Systematic Review and Meta-Analysis

Oral Candida albicans has been detected in children with early childhood caries (ECC) and has demonstrated cariogenic traits in animal models of the disease. Conversely, other studies found no positive correlation between C. albicans and caries experience in children, while suggesting it may have protective effects as a commensal organism. Thus, this study aimed to examine whether oral C. albicans is associated with ECC. Seven electronic databases were searched. The data from eligible studies were extracted, and the risk of bias was evaluated. A fixed effects model (Mantel-Haenszel estimate) was used for meta-analysis, and the summary effect measure was calculated by odds ratio (OR) and 95% confidence interval (CI). Fifteen cross-sectional studies were included for the qualitative assessment and 9 studies for meta-analysis. Twelve studies revealed higher oral C. albicans prevalence in ECC children than in caries-free children, while 2 studies indicated an equivalent prevalence. A pooled estimate, with OR = 6.51 and 95% CI = 4.94-8.57, indicated a significantly higher ECC experience in children with oral C. albicans than those without C. albicans (p < 0.01). The odds of experiencing ECC in children with C. albicans versus children without C. albicans were 5.26 for salivary, 6.69 for plaque, and 6.3 for oral swab samples. This systematic review indicates that children with oral C. albicans have >5 times higher odds of having ECC compared to those without C. albicans. Further prospective cohort studies are needed to determine whether C. albicans could be a risk factor for ECC, and whether it is dependent on different sample sources (saliva/plaque).

Management of dentin hypersensitivity by practitioners in the National Dental Practice-Based Research Network

BACKGROUND Dentin hypersensitivity (DH) is a condition commonly encountered in clinical dental practice. The authors conduct a study to identify the treatments recommended to manage DH among dentists in the United States. METHODS The authors conducted a multicenter study of 1,862 patients with DH who received a diagnosis and were treated by 171 dentists with The National Dental Practice-Based Research Network. RESULTS The most common treatment recommended was desensitizing over-the-counter (OTC) potassium nitrate toothpaste (alone or in combination with other treatments) for 924 of 1,862 patients (50%). This was followed by an application of fluoride varnish (FV) for 516 patients (28%) and a prescription for fluoride toothpaste for 314 patients (17%). Restorative treatments were recommended to 151 patients (8%). The most common single treatment recommendation was desensitizing OTC potassium nitrate toothpaste, recommended to 335 patients (18%). The most frequent combination of 2 treatment modalities was FV and desensitizing OTC potassium nitrate toothpaste, recommended to 100 patients (5%). A total of 890 of 1,862 patients (48%) with DH received a recommendation for 1 treatment modality, and 644 of 1,862 patients (35%) received a recommendation for a combination of 2 treatment modalities, most frequently an application of FV along with desensitizing OTC potassium nitrate toothpaste (100/1,862; 5%). CONCLUSIONS Desensitizing OTC potassium nitrate toothpaste and fluoride products were the most widely recommended products to manage DH in the practice setting. PRACTICAL IMPLICATIONS Our results suggest that most network clinicians preferred noninvasive treatment modalities when treating DH.

Management of Dentin Hypersensitivity by National Dental Practice-Based Research Network practitioners: results from a questionnaire administered prior to initiation of a clinical study on this topic

BackgroundDentin hypersensitivity (DH) is a common problem encountered in clinical practice. The purpose of this study was to identify the management approaches for DH among United States dentists.MethodsOne hundred eighty five National Dental Practice-Based Research Network clinicians completed a questionnaire regarding their preferred methods to diagnose and manage DH in the practice setting, and their beliefs about DH predisposing factors.ResultsAlmost all dentists (99%) reported using more than one method to diagnose DH. Most frequently, they reported using spontaneous patient reports coupled with excluding other causes of oral pain by direct clinical examination (48%); followed by applying an air blast (26%), applying cold water (12%), and obtaining patient reports after dentist’s query (6%). In managing DH, the most frequent first choice was desensitizing, over-the-counter (OTC), potassium nitrate toothpaste (48%), followed by fluorides (38%), and glutaraldehyde/HEMA (3%). A total of 86% of respondents reported using a combination of products when treating DH, most frequently using fluoride varnish and desensitizing OTC potassium nitrate toothpaste (70%). The most frequent predisposing factor leading to DH, as reported by the practitioners, was recessed gingiva (66%), followed by abrasion, erosion, abfraction/attrition lesions (59%) and bruxism (32%).ConclusionsThe majority of network practitioners use multiple methods to diagnose and manage DH. Desensitizing OTC potassium nitrate toothpaste and fluoride formulations are the most widely used products to manage DH in dental practice setting.

Compliance with dental treatment recommendations by rural paediatric patients after a live-video teledentistry consultation: A preliminary report

Objective The purpose of this research was to assess the compliance rate with recommended dental treatment by rural paediatric dental patients after a live-video teledentistry consultation. Methods A retrospective dental chart review was completed for 251 rural paediatric patients from the Finger Lakes region of New York State who had an initial teledentistry appointment with a paediatric dentist located remotely at the Eastman Institute for Oral Health in Rochester, NY. The recommended treatment modalities were tabulated and comprehensive dental treatment completion rates were obtained. Results The recommended treatment modality options of: treatment in the paediatric dental clinic; treatment using nitrous oxide anxiolysis; treatment with oral sedation; treatment in the operating room with general anaesthesia; or teleconsultation were identified for the 251 patients. Compliance rates for completed dental treatment based on initial teleconsultation recommendations were: 100% for treatment in the paediatric dental clinic; 56% for nitrous oxide patients; 87% for oral sedation; 93% for operating room; and 90% for teleconsultations. The differences in the compliance rates for all treatment modalities were not statistically significant (Fisher’s exact test, p > 0.05). Conclusions Compliance rates for completed comprehensive dental treatment for this rural population of paediatric dental patients were quite high, ranging from 56% to 100%, and tended to be higher when treatment was completed in fewer visits. Live-video teledentistry consultations conducted among rural paediatric patients and a paediatric dentist in the specialty clinic were feasible options for increasing dental treatment compliance rates when treating complex paediatric dental cases.
