Caries risk assessment in children: how accurate are we?

Validating Caries Risk Assessment Tools in High-Prevalence Filipino Toddlers

INTRODUCTION AND AIMS

Caries risk assessment is an essential part of the diagnostic process. Many studies have assessed these tools, proving their effectiveness in reducing future caries risk in developed countries with low caries prevalence. However, Filipino children have consistently registered high caries prevalence rates in successive official surveys. This prospective study aimed to compare the validity of available caries risk assessment tools in predicting future caries among a high-caries-prevalent population in the Philippines.

METHODS

From the vaccination registry of community health centres in Caloocan City, Philippines, children aged 4-24 months underwent oral examinations according to modified International Caries Detection and Assessment System (ICDAS) criteria, and their primary caregivers were interviewed using a structured questionnaire. Baseline caries risk categories were evaluated using 3 available tools, without biological tests. Caries incidence was recorded during the follow-up visit after 2 years.

RESULTS

Baseline oral examinations in 703 toddlers (mean age: 13.3 months, standard deviation (SD) 2.4) revealed a high caries prevalence of 29.2%. Of the 654 eligible children without cavitated caries at baseline, 323 (mean age: 35.6 months, SD 5.1) attended the 2-year follow-up visit, with a caries incidence (cavitated and non-cavitated) of 76.5%. Caries-risk Assessment Form (CrAF) demonstrated high sensitivity but low specificity scores (93.1% and 3.9%), while Caries Management by Risk Assessment (CAMBRA) showed similar patterns (71.7% and 34.2%). Conversely, Cariogram exhibited low sensitivity but high specificity (23.5% and 80.3%).

CONCLUSION

Among CrAF, CAMBRA or Cariogram, no assessment tool came close (sensitivity + specificity < 160) to effectively identify toddlers highly at risk of caries development.

CLINICAL RELEVANCE

Current CRA tools lack sufficient accuracy in predicting caries development in high-risk populations like Filipino children. Refinement or development of more valid tools is crucial for implementing effective caries prevention strategies at both individual and population levels.

Integrating oral and social factors in individual caries risk assessments in preschool children-a registry-based study

PURPOSE

To investigate the predictive ability of individual Caries Risk Assessments (CRA) regarding oral factors supplemented with social factors in relation to caries outcome in preschool children. Furthermore, to assess various models of CRA with oral and social factors included, aiming to identify the most suitable models for different age groups.

METHODS

The design is a retrospective registry-based cohort study. Children visiting the dentists at ages 3 and 6 years were included. Data on oral and social factors were obtained from dental records, the Swedish Quality register for caries and periodontitis (SKaPa), and Statistics Sweden (SCB). Various models of CRA were designed, combining oral and social factors. Models were analyzed with univariable associations using simple logistic regression, and the results were presented as odds ratios (ORs). In addition, models were analyzed with area under the receiver operating characteristic (ROC) curve (AUC). Pairwise comparisons were conducted by DeLong's test, with p < 0.05 considered significant.

RESULT

Oral factors were the most significant for caries outcome (OR 9.6), followed by social factors: foreign background (OR 4.6), low income (OR 2.83), low education of the mother (OR 2.77), single-parent family (OR 2.11), and having ≥ 3 siblings (OR 1.71), (p < 0.01). The predictive ability of CRA improved when models combining oral and social factors were used, compaired to CRA based solely on oral factors (p < 0.05). An increase of up to 15% was seen when CRA was conducted closer to the outcome.

CONCLUSION

Models for Caries Risk Assessment including oral and social factors increase the predictive ability. Caries Risk Assessment has limited durability.

Effectiveness of risk-based caries management among Chinese preschool children: a randomized controlled single-blind trial

BACKGROUND

Early childhood caries (ECC) remain a serious oral health problem on a global scale. Risk-based caries management (RBCM) implemented in some parts of the world has been effective in preventing ECC. However, there is a lack of prospective research on the application of RBCM among Chinese children, and little is known about its effectiveness. The purpose of this study was to evaluate the effectiveness of RBCM in preventing caries among children aged 3-5 years in Wanzhou District, Chongqing Municipality, China.

METHODS

Three- to five-year-old children from four kindergartens in Wanzhou were randomly selected for baseline dental examination and caries risk assessment (CRA) and randomly assigned to the experimental group (EG) or the control group (CG) according to the kindergarten. The EG received caries prevention measures of different intensities based on the child's caries risk level. The CG received full-mouth fluoride twice a year according to standard prevention, regardless of their caries risk. One year later, another dental examination and CRA were conducted, to observe changes in the decayed, missing, and filled teeth (dmft) index and caries risk, and to analyze potential factors that may affect the incidence of new caries.

RESULTS

Complete data were collected from 291 children (EG, N = 140, 84.8%; CG, N = 181, 83.4%). A total of 25.7% of the EG and 50.3% of the CG children developed new caries, with newly added dmft scores of 0.54 ± 1.12 and 1.32 ± 1.72, respectively (P < 0.05). Multivariate logistic regression indicated that children living in rural areas, assigned to the CG, and rated as high-risk at baseline were more likely to develop new caries (P < 0.05). The proportion of children with an increased caries risk in the EG was significantly lower than that in the CG (P < 0.05).

CONCLUSIONS

RBCM effectively prevented new caries in 3- to 5-year-old Wanzhou children and reduced the proportion of children at increased risk of caries. It is an effective approach for preventing ECC.

CLINICAL TRIAL REGISTRATION

This trial was registered in the Chinese Clinical Trials Register. The registration number was ChiCTR230067551 (11/01/2023).

Comparison of two different caries risk assessment tools for infants and toddlers - A cross-sectional study

CONTEXT

One of the essential components for successful caries management is caries risk assessment (CRA). Among CRA tools (CRATs) published in the literature: Caries management by risk assessment (CAMBRA) 123 and American Academy of Pediatric Dentistry (AAPD) CRATs are specifically designed for infants and toddlers.

AIMS

The aim of this study is to compare readily available internationally accepted CRAT for infants and toddlers and check the usability of these tools in assigning caries risk among the Indian population.

SETTINGS AND DESIGN

The study was conducted at Baby Oral Health Promotion Clinic, Department of Pediatrics, Tertiary Care Hospital using a cross-sectional study design.

SUBJECTS AND METHODS

Data were collected using CAMBRA 123 and AAPD CRATs from 379 children aged 0-6 years. The caries risk of the children was recorded with each CRAT and a comparison was made between the two tools used.

STATISTICAL ANALYSIS USED

The percentage of agreement and Cohen's kappa coefficient were used to know the agreement between the CAMBRA 123 and AAPD CRATs using the SPSS statistical tool. The significance level was set at 5% (α = 0.05).

RESULTS

For children aged <2 years, the study showed slight agreement between the CAMBRA 123 and AAPD, whereas, for children more than 2 years, there was a fair agreement between the two methods which was statistically significant. This indicates that the agreement between the two methods is still not perfectly established, and AAPD CRA assigns a higher risk category than CAMBRA 123.

CONCLUSIONS

CAMBRA 123 is a promising user-friendly quantitative method for CRA in clinical practice. Since there is ambiguity in assessing the caries risk in children <2 years, there is a need to establish a CRAT that can be used exclusively for children below 2 years.

Does the Modality of Dental Treatment Affect the Treatment Prognosis and the Necessity of Re-Treatments?

BACKGROUND

The utilization of evidence-based approaches is crucial to achieving long-term positive outcomes for treatment performed chairside or under general anesthesia. The study aimed to evaluate if treatment modality (at the chairside or under general anesthesia) affects prognosis and the need for re-treatment.

METHODS

Oral-hygiene, gingival, and plaque indexes were recorded during the control appointment. The success of all treatments was evaluated according to the scoring of particular evaluation criteria.

RESULTS

A total of 1066 dental procedures were performed on 92 children. Plaque index scores were higher for patients treated under general anesthesia. The success rate of restorative procedures was 82.5% under general anesthesia and 80.6% at the chairside. There was no statistically significant difference between the mean number of restorative treatments and the need for re-treatment between general anesthesia or chairside (p = 0.649, p = 0.311). The mean number of unsuccessful endodontic treatments performed under general anesthesia was higher than performed chairside. Only two out of thirty stainless-steel crowns were decemented, all performed under general anesthesia.

CONCLUSIONS

The high volume of restoration failure due to secondary caries has highlighted the need for alternative approaches to caries management, especially given the risks associated with repeat general anesthetic.

Comparative Assessment of Retention and Caries Protective Effectiveness of a Hydrophilic and a Conventional Sealant-A Clinical Trial

Sealants are highly efficient and the most secure method for the prevention of caries lesions from pits and fissures in recently erupted permanent teeth. The aim of this study is to clinically assess and compare the retention and evolution of caries of a moisture-tolerant resin-based sealant with a conventional hydrophobic resin-based sealant. Material and method: We have included in the study 28 children with between 6 and 8 years old. For each child we sealed 4 permanent molars (a total of 112 teeth). The study group was divided into two subgroups: the Embrace Group—consisting of 56 first permanent molars that underwent dental sealing with moisture-tolerant resin-based fissure sealant (Embrace™ WetBond™ Pulpdent, Watertown, MA, USA) and the Helioseal Group—represented by the same number of 56 first permanent molars that were sealed with conventional hydrophobic resin-based sealant (Helioseal F™, Ivoclar Vivadent Schaan, Liechtenstein). The retention and the incidence of new carious lesions of each sealant were assessed clinically at 6, 12, 18, and 24 months. Results: The 12-month follow-up assessment showed perfect integrity in 50 molars (89.28%) sealed with moisture-tolerant resin-based material (Embrace Group), and in 51 molars (91.07%) with conventional resin-based sealant (Helioseal Group). At the 24-month recall, the retention was maintained in 44 molars (78.57%) in the Embrace Group and in 45 molars (80.35%) in the Helioseal Group, respectively. The follow-up assessments showed no statistically significant differences (p > 0.5) between the two materials regarding sealant retention. First evidence of new carious lesions was present at 12 months on two molars sealed with Embrace WetBond and on one molar sealed with Helioseal. At the 24-month evaluation, the prevalence of caries in the Embrace Group was 7.14% (four caries) and 3.56% (two caries) in the Helioseal Group. Moreover, there were no statistically significant differences (p > 0.05) between the two materials regarding new caries development at any of the follow-up assessments. Conclusions: Moisture-tolerant resin-based sealant was effective in terms of retention and caries prevention.

Effectiveness of the ICCMS caries management system for children: a 3-year multicentre randomised controlled trial

OBJECTIVE

This 3-year multicentre randomised controlled trial compared, in 6-7-year-old Colombian children, the effectiveness of the ICCMS (International Caries Classification and Management System) with a conventional caries-management system (CCMS) in terms of individual caries-risk, caries lesions, and secondarily, oral-health-related knowledge/attitudes/practices, and number of appointments.

MATERIAL AND METHODS

With ethical approval, 240 6-7-year olds from six Colombian clinics were recruited. Trained examiners conducted the following baseline/follow-up assessments: Caries risk (Cariogram-ICCMS); caries severity/activity staging (ICDAS-merged combined radiographic/visual); sealants/fillings/missing teeth, and oral-health-related knowledge, attitudes and practices. Children received their randomly allocated (ICCMS/CCMS) care from dental practitioners. Outcomes: caries-risk control (children); caries-progression control (tooth surfaces); oral-health-related knowledge/attitudes/practices improvement (parents/children), and appointments' number (children). Descriptive and non-parametric/parametric bivariate analyses were performed.

RESULTS

Three-year-follow-up: n = 187 (77.9%; ICCMS: n = 92; CCMS: n = 95) disclosed a baseline-to-3-year overall high-caries-risk children decrease (ICCMS: 60.9-0%, p < .001; CCMS: 54.7-5.3%, p < .001) (p > .05). ICCMS versus CCMS showed: fewer tooth-surface caries progression (6.2% vs 7.1%, p = .010) and fewer active-caries lesions (49.8% vs. 59.1%, p < .05); higher proportion of children with ≥2/day fluoride-toothpaste tooth-brushing practice (p < .05); similar mean number of appointments (10.9 ± 5.9 vs. 10.0 ± 3.8, p = .15).

CONCLUSION

Both caries-management systems showed similar effectiveness in caries-risk control, with ICCMS more effectively controlling tooth-surface caries progression and improving toothbrushing practices.

Risk Indicators and Treatment Needs of Children 2-5 Years of Age Receiving Dental Treatment under General Anesthesia in Saskatchewan

BACKGROUND

When compared to national averages in Canada, Saskatchewan has one of the highest rates of dental treatment under general anesthesia (GA) and average costs per child. Thus, the purpose of this cross-sectional study is to explore the risk indicators and treatment needs of children receiving dental treatment under GA in Saskatchewan.

METHODS

In this cross-sectional study, we recruited caregivers of children between 24 and 71 months of age in Saskatoon, Canada. Caregivers completed a 40-item questionnaire, which was supplemented with clinical data and then subject to statistical analysis (independent t-tests and one-way ANOVA).

RESULTS

A total of 90 caregiver/child dyads were enrolled with the mean age for children being 49.5 ± 12.3 months. The mean age of a child's first dental visit was 34.7 ± 15.3 months with only 37.9% of children having a dental home. The mean deft index was 11.7 ± 3.4, with an average of 10.9 ± 3.5 teeth receiving treatment. Additionally, location of primary residence (p = 0.03), family income (p = 0.04), family size (p = 0.01), parental education (p = 0.03), dental home (p = 0.04), and body mass index (p = 0.04) had a statistically significant association with a higher mean deft.

CONCLUSIONS

Our cross-sectional study confirms that children who require dental treatment under GA have a high burden of disease. While individual risk indicators such as diet and oral hygiene play a role in the progression of early childhood caries (ECC), we also demonstrate that children who do not have access to early preventive visits or a dental home are at a higher risk. In addition to improving motivation for oral hygiene at home and nutritional education, improving access to oral health care should be addressed in strategies to reduce ECC.

Randomized clinical trial to evaluate two methods of caries risk assessment in schoolchildren: the CARDEC-PEL 04 study protocol

Background

Caries risk assessment is an essential element for managing and preventing dental caries in children. Individual caries risk assessment can be conducted to evaluate the presence or absence of single factors, or using multivariate models, a combination of factors. The subject has been extensively studied, but no previous research has compared whether a more elaborate and individualized method of caries risk benefits the patient than more straightforward strategies. Thus, this protocol evaluates the efficacy of two risk assessment methods for caries control in children, a simplified method based on caries experience evaluation and a multivariate method described in the literature.

Methods

This is a randomized, double-blind, controlled, parallel-treatment trial protocol. Two groups will be tested for two forms of caries risk assessment: an individualized and detailed multivariate method based on the guidelines of the Caries Care International 4D and another simplified process, based only on caries experience in primary and/or permanent dentition, considering the presence of decayed, missing and filled teeth using the DMFT/dmft index. Participants will be children aged 8 to 11 years, followed up at 12 and 24 months. The primary outcome will be a composite outcome representing the number of tooth surfaces requiring operative intervention (account variable). In addition, the Shapiro–Wilk normality test and Student's t-test will be performed. A multivariate analysis using negative binomial regression will compare groups in the intention-to-treat population, considering a two-tailed significance level of 5%.

Discussion

This is the first randomized clinical trial aiming to compare dental caries-related treatment and follow-up based on a detailed, multivariate and individualized assessment of caries risk in school-age children to a simpler risk assessment strategy based on caries experience. This study will define whether there are essential benefits to the patient that justify the choice of one method over the other.

Fissure sealant therapy as a portable community-based care in deprived regions: Effectiveness of a clinical trial after 1 year follow-up

The aim of this study was to evaluate the effectiveness of the fissure sealant therapy in suboptimal setting (as part of a community-based program using the portable equipment and provided by dental students) on the caries status of school children. This pragmatic split-mouth randomised clinical trial was conducted in rural area of Iran. At baseline, 124 patients, including 185 paired teeth with deep pits and fissures of opposite quadrants that were either healthy or at early stages of enamel decay (International Caries Detection and Assessment System [ICDAS] 0-2), were randomly allocated to receive fissure sealant or acted as control. The incidence of new caries (ICDAS code 3-6) and the sealant's retention status after 1-year follow-up were evaluated. Using chi-square test, the relative risk (RR) and the Number Needed to Treat (NNT) to prevent new caries were calculated. After 1 year, 109 patients including 163 paired teeth were available. Sixty-seven (41.4%) and 44 (27.2%) teeth had complete and partial retained sealants respectively. The risk of caries incidence in non-sealed teeth was almost three times more than sealed teeth (RR = 2.88, 95% CI: 1.4-1.97, p = 0.002) and the NNT was 10 (95% CI: 6-26). A significant association was noted between the status of sealant retention after 1 year and the incidence of new caries (p < 0.001). Fissure sealant as part of a community-based program was effective in controlling caries incidence.

Risk factors for dental caries in Latin American and Caribbean countries

Identifying the risk factors for dental caries is vital in epidemiology and clinical practices for developing effective preventive strategies, both, at the individual and collective levels. Different causality/determination models have been proposed to understand the development process of dental caries. In the present review, we designed a model inspired by the world-known social determinants models proposed in the 90s and more recently in the 10s, wherein the contextual factors are placed more externally and encompass the individual factors. The contextual factors included those related to the cultural and societal values, as well as the social and health government policies. The individual factors were classified into the following categories: socioeconomic (social class, occupation, income, and education level), demographic characteristics (age, sex, and ethnicity), behavioral factors (non-use of fluoride dentifrice, sugar consumption, poor oral hygiene, and lack of preventive dental care), and biological factors (recent caries experience/active caries lesions, biofilm retentive factors, developmental defects of the enamel, disabilities, saliva amount and quality, cariogenic biofilm). Each of these variables was addressed, while focusing on the current evidence from studies conducted in Latin American and Caribbean countries (LACC). Based on the proposed model, educational aspects were addressed, and individual caries risk assessment and management decisions were proposed; further, implications for public health policies and clinical practice were described. The identification of modifiable risk factors for dental caries should be the basis for multi-strategy actions that consider the diversity of Latin American communities.

Effect of a Preventive Oral Health Program Starting during Pregnancy: A Case-Control Study Comparing Immigrant and Native Women and Their Children

The objective was to evaluate whether including pregnant women in a preventive dental program prevented the appearance of caries in their children up to the age of 6, and whether the effect was similar in children of immigrant and non-immigrant women. In phase I, 90 pregnant women, 45 immigrants and 45 natives, were taught about the development and prevention of caries. In phase II the oral health of their children at the age of 6 (n = 90) was evaluated, along with a control group of children of natives and immigrants of the same age (n = 90). A survey was used to determine participants' backgrounds and habits. A multivariate study of the results was performed using R-core software. The number of children without caries was 128 (71.1%), whereas 52 (28.9%) had caries, 15 from the protocol (16.67%) and 37 from the control group (41.11%), with statistically significant differences (p < 0.001). The mean number of caries for the children in the protocol was 0.62 ± 2 and in the control group it was 1.88 ± 2.9 (p = 0.001). In the multivariate analysis the risk of developing caries was higher for the condition of being the child of an immigrant (OR = 11.137), inadequate oral health (OR = 4.993), the children being overweight at the age of 6 (OR = 10.680), and the consumption of candies (OR = 5.042). In conclusion, the preventive protocols started during pregnancy reduced caries in participants' children, which suggests that these protocols should be encouraged. Because immigrant children are more vulnerable to caries, they and their parents should be included in preventive programs once they arrive in the host country.

Early childhood caries risk assessment in 1-year-olds evaluated at 6-years of age

OBJECTIVES

The aim was to identify caries risk factors in 1-year-olds predicting dentine caries in 6-year-olds.

MATERIALS AND METHODS

Caries risk assessment was performed in 804 one-year-olds. Their parents answered a questionnaire, regarding family factors, general health, food habits and oral hygiene. Clinical examinations and caries risk assessments at 1, 3 and 6 years of age were performed. Simple and multiple regression analyses were used for identification of caries-associated factors.

RESULTS

Caries risk was found in 5% of the 1-year-olds, and 12% of the 3-year-olds. Dentine caries was found in 3% of the 3-year-olds and in 16% of the 6-year-olds. Caries risk assessment was associated with caries at 6 years of age (OR = 5.1, p < .001). Multiple logistic regression analysis found the following variables associated with caries at 6 years of age: Caries in sibling (OR = 2.1, p = .012), Beverage other than water (OR = 2.1, p < .001), Night meal (OR = 1.9, p = .002), Presence of mutans streptococci (MS) (OR = 1.6, p = .033) and Male gender (OR = 1.5, p = .053). An overall caries risk assessment was more reliable than any single caries risk factor.

CONCLUSIONS

Caries risk assessment for 1-year-olds in a region with low caries prevalence has limited accuracy to predict dental caries at 6 years of age. Caries risk often changes over time and should be reassessed on a regularly basis. The presence of MS in 1-year-olds did not increase the prognostic accuracy at 6 years of age.

Pit and fissure sealants versus fluoride varnishes for preventing dental decay in the permanent teeth of children and adolescents

BACKGROUND

Most of the detected increment in dental caries among children above the age of six years and adolescents is confined to occlusal surfaces of posterior permanent molars. Dental sealants and fluoride varnishes are much used to prevent caries. As the effectiveness of both interventions in controlling caries as compared with no intervention has been demonstrated previously, this review aimed to evaluate their relative effectiveness. It updates a review published originally in 2006 and updated in 2010 and in 2016.

OBJECTIVES

Our primary objective was to evaluate the relative effectiveness of dental sealants (i.e. fissure sealant) compared with fluoride varnishes, or fissure sealants plus fluoride varnishes compared with fluoride varnishes alone, for preventing dental caries in the occlusal surfaces of permanent teeth of children and adolescents. Our secondary objectives were to evaluate whether effectiveness is influenced by sealant material type and length of follow-up, document and report on data concerning adverse events associated with sealants and fluoride varnishes, and report the cost effectiveness of dental sealants versus fluoride varnish in caries prevention.

SEARCH METHODS

Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 19 March 2020), the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2020, Issue 2), MEDLINE Ovid (1946 to 19 March 2020) and Embase Ovid (1980 to 19 March 2020). We searched the US National Institutes of Health Trials Registry (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform for ongoing trials. There were no restrictions on the language or date of publication.

SELECTION CRITERIA

We included randomised controlled trials with at least 12 months of follow-up comparing fissure sealants, or fissure sealants plus fluoride varnishes, versus fluoride varnishes, for preventing caries in the occlusal surfaces of permanent posterior teeth (i.e. premolar or molar teeth), in participants younger than 20 years of age at the start of the study.

DATA COLLECTION AND ANALYSIS

At least two review authors independently screened search results, extracted data from included studies and assessed their risk of bias. We attempted to contact study authors to obtain missing or unclear information. We grouped and analysed studies on the basis of sealant material type: resin-based sealant or glass ionomer-based sealant (glass ionomer and resin-modified glass ionomer sealant), and different follow-up periods. We calculated the odds ratio (OR) for risk of caries on occlusal surfaces of permanent molar teeth. For trials with a split-mouth design, we used the Becker-Balagtas OR. One cluster-randomised trial provided precise estimates in terms of risk ratio (RR), which we used. For continuous outcomes and data, we used means and standard deviations to obtain mean differences (MD). For meta-analysis, we used the random-effects model when we combined data from four or more studies. We presented all measures with 95% confidence intervals (CIs). We assessed the certainty of the evidence using GRADE criteria.

MAIN RESULTS

We included 11 trials with 3374 participants aged five to 10 years when trials started. Three trials are new since the 2016 update. Two trials did not contribute data to our analysis. Sealant versus fluoride varnish Resin-based fissure sealants versus fluoride varnishes Seven trials evaluated this comparison (five contributing data). We are uncertain if resin-based sealants may be better than fluoride varnish, or vice versa, for preventing caries in first permanent molars at two to three years' follow-up (OR 0.67, 95% CI 0.37 to 1.19; I² = 84%; 4 studies, 1683 children evaluated). One study measuring decayed, missing and filled permanent surfaces (DMFS) and decayed, missing and filled permanent teeth (DMFT) increment at two years suggested a small benefit for fissure sealant (DMFS MD -0.09, 95% CI -0.15 to -0.03; DMFT MD -0.08, 95% CI -0.14 to -0.02; 542 participants), though this may not be clinically significant. One small study, at high risk of bias, reported a benefit for sealant after four years in preventing caries (RR 0.42, 95% CI 0.21 to 0.84; 75 children) and at nine years (RR 0.48, 95% CI 0.29 to 0.79; 75 children). We assessed each of these results as having very low certainty. Glass ionomer-based sealants versus fluoride varnishes Three trials evaluated this comparison: one trial with chemically cured glass ionomer and two with resin-modified glass ionomer. Studies were clinically diverse, so we did not conduct a meta-analysis. In general, the studies found no benefit of one intervention over another at one, two and three years, although one study, which also included oral health education, suggested a benefit from sealants over varnish for children at high risk of caries. We assessed this evidence as very low certainty. Sealant plus fluoride varnish versus fluoride varnish alone One split-mouth trial analysing 92 children at two-year follow-up found in favour of resin-based fissure sealant plus fluoride varnish over fluoride varnish only (OR 0.30, 95% CI 0.17 to 0.55), which represented a clinically meaningful effect of a 77% reduction in caries after two years; however, we assessed this evidence as very low certainty. Adverse events Five trials (1801 participants) (four using resin-based sealant material and one using resin-modified glass ionomer) reported that no adverse events resulted from use of sealants or fluoride varnishes over one to nine years. The other studies did not mention adverse events.

AUTHORS' CONCLUSIONS

Applying fluoride varnish or resin-based fissure sealants to first permanent molars helps prevent occlusal caries, but it has not been possible in this review to reach reliable conclusions about which one is better to apply. The available studies do not suggest either intervention is superior, but we assessed this evidence as having very low certainty. We found very low-certainty evidence that placing resin-based sealant as well as applying fluoride varnish works better than applying fluoride varnish alone. Fourteen studies are currently ongoing and their findings may allow us to draw firmer conclusions about whether sealants and varnish work equally well or whether one is better than the other.

The Association of Caries Increment Dynamics in Preschool Children with Risk Factors: The 3-Year Prospective Study

This prospective study monitored the dental status, the presence of plaque, and cariogenic microorganism levels of identical children over three years. The aim was to determine the dynamics of caries increment as well as the relationship between risk factors and caries prevalence. A total number of 125 children (72 boys and 53 girls) was included in the study, with an average age of 3.95 ± 0.06 years at the baseline. During the clinical examination at the nursery schools, the presence of dental plaque was recorded, and saliva samples were collected from the tongue of children for the DentoCult SM test providing easy detection of mutans streptococci from saliva samples. At baseline, 65.6% of the children had no caries, 4% had restored teeth with fillings or crowns or missing teeth due to caries, and 30.4% had at least one untreated caries. The percentages of intact teeth, restored or missing teeth, and untreated caries were 52.8%, 8.8%, 38.4% in the second year and 49.1%, 13.8%, and 31.1% in the third year. The dmft index value was 1.41 ± 0.24 in the first year, 2.29 ± 0.30 in the second year, and 2.33 ± 0.31 in the third year. There was a significant correlation between plaque presence and dt and dmft values (p < 0.05; the statistical analyses were performed using the Kolmogorov-Smirnov test). This 3-year longitudinal study highlighted the importance of examining both the oral hygiene and the level of cariogenic microorganisms when undertaking the evaluation of caries risk evaluation in preschool children.

Inequality, Familial Aggregation, and Risk Prediction of Caries in Siblings

INTRODUCTION

Social and family conditions are likely of great importance to dental health; however, limited evidence of familial aggregation of caries among adolescent siblings exists. Moreover, social and family-level factors have never been evaluated as isolated caries predictors at the individual level.

OBJECTIVES

The objectives were to evaluate socioeconomic patterning of caries among siblings, assess sibling-specific aggregation of caries within families, and examine if such aggregation differed by parental socioeconomic position (SEP). We also evaluated the discriminant ability of sibling caries, SEP, and other social and familial factors in predicting caries in cosiblings.

METHODS

This nationwide register-based study included all 15-y-olds in Denmark in 2003 (index siblings) and their biological siblings born within ±3 y (cosiblings). Clinical and sociodemographic data for each subject were compiled from Danish national dental, social, and population registers. Caries was measured by the decayed, missing, and filled tooth surfaces (DMFS) index. Predictors included SEP (parental education, income, and occupational social class), gender, birth order, immigration status, and household type. Adjusted SEP-caries associations were estimated using negative binomial regression. Familial aggregation was evaluated using adjusted pairwise odds ratios from alternating logistic regressions. Caries prediction was based on classification and regression tree (CART) analyses.

RESULTS

The study included 23,847 sibling pairs (n = 47,694). Socioeconomic patterning of caries was similar among the index and cosiblings with significant graded SEP-caries associations. Significant sibling-specific aggregation of caries was observed; cosiblings of caries-affected index siblings had odds of having caries 3.9 times (95% confidence interval: 3.65-4.18) as high as that of cosiblings with caries-free index siblings. This sibling similarity was stronger in socioeconomically disadvantaged families (adjusted pairwise odds ratios: 3.08-5.47). CART revealed index sibling caries as the single most important caries predictor, with caries predicted in ≥84% of cosiblings of adolescents with ≥3 carious tooth surfaces.

CONCLUSIONS

Caries in a sibling should prompt preventive family-based approaches targeting cosiblings.

KNOWLEDGE TRANSFER STATEMENT

This study revealed significant socioeconomic patterning of caries in adolescent siblings. Prediction modeling indicated that the single most important caries predictor among cosiblings was index sibling caries. Information on sibling caries level should be routinely combined with clinical evaluation to identify children at risk. Moreover, information on social and family conditions should be used to target prevention and health promotion at the school or municipal level. These approaches could possibly contribute to reducing the existing caries inequalities.

Saliva as a diagnostic tool for dental caries, periodontal disease and cancer: is there a need for more biomarkers?

Introduction: A biomarker is a biological indicator of normal or pathogenic processes. Identification of biomarkers is useful for the prevention, diagnosis and prognosis of diseases as well as for monitoring the progression of pathological disorders. Several types of molecules present in biological fluids can act as biomarkers such as DNA, coding and non-coding RNA, lipids, metabolites, proteins and even microbes. In this context, saliva emerges as a useful diagnostic tool for the detection of biomarkers involved with oral and systemic diseases, since it reflects the pathophysiological conditions of the organism and allows early, rapid, practical and noninvasive detection of biomarkers.Areas covered: This review discusses the properties of saliva as a diagnostic tool and addresses the main identified biomarkers related to dental caries, periodontal disease, head and neck cancer and other types of cancer of considerable incidence among the world population.Expert commentary: Despite extensive efforts which have been directed toward the identification of one or a combination of biomarkers with good predictive values for the early detection of dental caries, periodontal disease and cancer, these biomarkers still need validation before chairside point-of-care devices can be widely used in the clinic.

Risk Factors Associated with Carious Lesions in Permanent First Molars in Children: A Seven-Year Retrospective Cohort Study

The aim of this study was to evaluate the risk factors associated with the occurrence of caries in permanent teeth (PT) and in the permanent first molar (PFM) seven years after their eruption. Children born in 2005 who were enrolled in a Community Dental Program were included. A total of 278 children were enrolled. Evaluated risk factors were parental caries experience, educational level of the mother, routine medications, systemic diseases, dietary habits, toothbrushing frequency, existence of molar incisor hypomineralization (MIH) in the PT, and caries in the temporary teeth (TT). Associations between independent variables and the DMF-T (decayed, missing, and filled teeth in PT) and DMF-M (DMF in PFM) indices, only considering cavitated and non-cavitated carious lesions or cavitated carious lesions as outcomes, were evaluated by Poisson regression with robust variance analysis. A cariogenic diet (sweets and soft drinks), toothbrushing frequency of <1 a day, a presence of df-t (decayed and filled temporary teeth) score of >0, low educational level of the mother, and existence of MIH were associated with high DMF-T or DMF-M values (p < 0.05). We can conclude that the intake of sweets and soft drinks, toothbrushing frequency, the presence of caries in TT, and MIH in PT were the best predictors of the occurrence of caries in PT and PFM.

Feasibility and usability of measuring receipt of sealants in 2 states

BACKGROUND

The authors examined the reliability and validity of the Dental Quality Alliance childhood sealant measure under actual use conditions in Texas and Florida. The 2 states provide care for almost 20% of children in Medicaid nationally.

METHODS

The authors used dental claims data to examine the reliability of the caries risk assessment component of the measure. They examined validity using a 3-year look-back period to identify children who were inaccurately included in the measure denominator as sealant eligible when they were not owing to already sealed, missing, or restored teeth.

RESULTS

The children identified at elevated risk varied between the states, with 85% at elevated risk in Texas and 39% in Florida in 2017. Different methods can be used to calculate risk, raising questions about reliability. In Texas, 31% of children included in the denominator were not eligible to receive sealants owing to already sealed, missing, or restored teeth. The magnitude of the underestimation increased with age, so by the time children were 9 years old, 40% were not measure eligible yet included in the denominator. Similar results were observed for Florida.

CONCLUSIONS

The authors propose eliminating the caries risk assessment requirement and incorporating a 3-year look-back period to identify already sealed, missing, or restored molars.

PRACTICAL IMPLICATIONS

The reliability and validity of the sealant measure needs to be enhanced. Measure misspecification in which children are not correctly identified as needing sealants can contribute to inaccurate development of quality improvement goals, performance improvement projects, or pay-for-quality programs.

Success of Two Caries Risk Assessment Tools in Children: A Pilot Study With a 3-Year Follow-Up

Caries risk is defined as the dental caries probability under the individual bacteriological environment, dietary habits, and environmental factors. Assessment of caries risk plays a major role in the prevention of dental caries. The aim of this study was to compare the effectiveness of two different caries risk assessment methods on caries-free preschool children. A sample of 90 caries-free 4- to 6-year-old children were selected from 400 preschool children. The selection was limited to children who had no dental caries, visible plaque, and systemic disease. American Academy of Pediatric Dentistry’s Caries Risk Assessment Tool (CAT) and Clinpro Cario L-Pop (CCLP; 3M ESPE, Germany) were used to categorize children into caries risk groups. Children were classified as being in high-, medium-, or low-risk groups by two methods. Determining risk factors according to CAT were examined. The compliance among the two methods was evaluated. Sixty-eight children were reevaluated intraorally after 3 years. The compliance between CAT and CCLP was sought using Kappa test. Statistical evaluation revealed moderate compliance among methods at baseline. The three most determinant factors in the high-risk group according to CAT were no topical fluoride exposure, no use of dental services, and active caries in mother. CAT is found statistically more successful than CCLP in predicting caries risk 3 years later. Caries risk assessment is effective to predict future caries and can be helpful for the clinician to choose the right tailor-made caries prevention plans.

Caries incidence and risk assessment during a five-year period in adolescents living in south-eastern Sweden

OBJECTIVES

The aim was to examine the caries incidence in adolescents using the Public Dental Service (PDS) during a 5-year period in relation to their caries experience at baseline and risk classification.

METHODS

A 5-year retrospective cohort study based of the dental records from 17 PDS clinics in south-eastern Sweden was conducted; 159 individuals born in 1997 were included, and their caries risk was classified at 12 and 17 years of age. Caries prevalence and documented risk groups were assessed at baseline and after 5 years.

RESULTS

The increment of caries (both initial and manifest caries) was higher, to a statistically significant degree, after 5 years in adolescents who were recorded as caries-free at baseline compared to individuals with caries at baseline (P < .001). In individuals with caries at baseline, the greatest increment of caries was found at approximal sites (P < .001). At baseline, individuals were classified as low (94%), medium (6%) and high risk (0%). After 5 years, the figures were 74%, 20% and 6%, respectively. Although classified in a low-caries risk group, 9% had ≥6 decayed or filled surfaces at baseline, and 23% did after 5 years. Approximately 62% of individuals were registered as caries-free at baseline, and 45% were after 5 years.

CONCLUSIONS

There was an increase in caries over 5 years, especially among adolescents without caries experience at baseline. The majority of adolescents had the same risk classification after 5 years. Further research with a larger sample size is needed to evaluate risk assessment for caries.

Dental plaque pH in predicting caries relapse after general anaesthesia - an exploratory study

OBJECTIVES

Numerous caries risk assessment tools have been proposed in the literature, with few validated in preschool children especially those receiving oral rehabilitation under general anaesthesia (GA). Past caries experience, the best predictor thus far, may not be a reliable indicator after effective clinical intervention. Hence, this longitudinal study was aimed to explore the potential role of plaque pH in predicting future caries incidence after GA among preschool children.

METHODS

Oral examination, plaque pH measurements and questionnaire survey were performed, among pre-schoolers indicated for GA, at baseline (n = 92), 6-month (6M; n = 83), 12-month (12M; n = 79) and 24-month (24M; n = 66) recall visits after GA. Multivariable logistic regression and receiver-operating characteristic analysis were performed to evaluate the predictive value of models with plaque pH and past caries experience.

RESULTS

Individuals with low resting plaque pH at 6M and 12M were shown to be at high risk of 1-year caries incidence at 12M [relative risk (RR) 1.41, 95% confidence interval (CI) 1.09-1.48] and 24M (RR 1.61, 95% CI 1.22-1.73) recall visit, respectively. Moreover, plaque pH demonstrated a statistically significant predictive value in the 12M and 24M models (12M/24M: 85%/77%) compared with past caries experience, which was not a significant predictor in both models (both P > 0.05).

CONCLUSIONS

Plaque pH may be a promising prognostic and predictive marker for early identification of high-risk children undergoing oral rehabilitation under GA.

Validation of different Cariogram settings and factor combinations in preschool children from areas with high caries risk

BACKGROUND

Caries risk assessment in preschool children has been limited validated.

AIM

To validate caries predictive ability of Cariogram using different combinations of factors and settings in preschool children from areas with high caries risk.

DESIGN

Two to five years old children (N = 175) were examined for caries (cavitated and non-cavitated lesions), at baseline and after 1 and 2 years. Mutans streptococci counts (MS) and saliva buffer capacity (SBC) were measured with chair side tests. Diet and oral health attitude were assessed through a parental questionnaire. Baseline caries risk was calculated using standard and high-risk group variables in Cariogram either with nine factors or excluding MS and SBC. Poisson regression models, ROC analysis and information criteria (AIC and BIC), P < 0.05, were used to investigate the predictive ability of Cariograms and to quantify the associations.

RESULTS

Accuracy of Cariogram was found limited. Cariograms with MS showed higher sensitivity but lower specificity than those without bacterial counts. Standard set Cariograms with MS counts performed slightly better than the other models, but the difference was not statistically significant. Caries prediction with standard and high set Cariograms was also found limited.

CONCLUSIONS

Cariogram with various factors and settings displayed suboptimal ability to predict caries in this population.

Early childhood caries epidemiology, aetiology, risk assessment, societal burden, management, education, and policy: Global perspective

BACKGROUND

This paper is a summary of the proceedings of the International Association of Paediatric Dentistry Bangkok Conference on early childhood caries (ECC) held in 3-4 November 2018.

AIM

The paper aims to convey a global perspective of ECC definitions, aetiology, risk factors, societal costs, management, educational curriculum, and policy.

DESIGN

This global perspective on ECC is the compilation of the state of science, current concepts, and literature regarding ECC from worldwide experts on ECC.

RESULTS

Early childhood caries is related to frequent sugar consumption in an environment of enamel adherent, acid-producing bacteria in a complex biofilm, as well as developmental defects of enamel. The seriousness, societal costs, and impact on quality of life of dental caries in pre-school children are enormous. Worldwide data show that ECC continues to be highly prevalent, yet infrequently treated. Approaches to reduce the prevalence include interventions that start in the first year of a child's life, evidence-based and risk-based management, and reimbursement systems that foster preventive care.

CONCLUSIONS

This global perspective on ECC epidemiology, aetiology, risk assessment, global impact, and management is aimed to foster improved worldwide understanding and management of ECC.

The impact of ICDAS on occlusal caries treatment recommendations for high caries risk patients: an in vitro study

Background

The diagnostic criteria and tools used in caries lesion detection have been shown to affect the decision-making for caries treatment. Compared to other diagnostic criteria/classifications, ICDAS has been shown to provide a more accurate method for the detection of occlusal caries lesions. The influence of using ICDAS on caries treatment recommendations has received increasing attention in recent years. Therefore, the aim of this study was to assess the impact of ICDAS on dentists’ occlusal caries lesions’ treatment decisions for patients at high risk for caries.

Methods

Five dentists examined the occlusal surfaces of 270 extracted premolars and permanent molars. For a predetermined clinical scenario, the examiners were asked to indicate their treatment recommendations for each tooth. Four weeks later, all the examiners were trained and calibrated for the use of ICDAS. Then the investigators examined the same 270 teeth independently and indicated their treatment recommendations using the same clinical scenario. Histological validation was used to determine the caries lesions detection performance of the examiners using ICDAS and to assess the relationship between the presence of dentin caries and treatment recommendations for each examiner before and after ICDAS training. Specificity, sensitivity, area under the receiver operating characteristic curve (AUC), and Spearman’s correlation coefficients were calculated. The Wilcoxon two-related sample rank test was used to test for differences between treatment recommendations.

Results

The strongest correlation for inter-examiner reproducibility was found between the ICDAS D2 cut-off point (ICDAS codes 3–6 as dentin caries) and histologic dentin caries. Treatment recommendations among different examiners before and after ICDAS training demonstrated a statistically significant increase in operative intervention and an increase in the percentage of overtreatment recommendations for two examiners.

Conclusions

The impact of ICDAS on the examiners’ caries lesion treatment recommendations varied among the dentists in this study. Treatment decision-making can be influenced by the caries lesion’s detection and classification system used.

Caries risk/susceptibility assessment: its value in minimum intervention oral healthcare

This narrative review describes the intimate connection between minimum intervention (MI) oral healthcare and caries risk/susceptibility assessment (CRA). Indeed CRA is the corner stone of an MI care plan, allowing the determination of the appropriate interventions (non-invasive as well as invasive [restorative]) and recall consultation strategies. Various CRA protocols/models have been developed to assist the oral healthcare practitioner/team in a logical systematic approach to synthesising information about a disease that has a multifactorial aetiology. Despite the criticisms toward the lack of clear-cut validation of the proposed protocols/models, CRA still has great potential to enhance patient care by allowing the oral healthcare practitioner/team and the patient to understand the specific reasons for their caries activity and to tailor their care plans and recall intervals accordingly.

Deep Artificial Neural Networks for the Diagnostic of Caries Using Socioeconomic and Nutritional Features as Determinants: Data from NHANES 2013⁻2014

Oral health represents an essential component in the quality of life of people, being a determinant factor in general health since it may affect the risk of suffering other conditions, such as chronic diseases. Oral diseases have become one of the main public health problems, where dental caries is the condition that most affects oral health worldwide, occurring in about 90% of the global population. This condition has been considered a challenge because of its high prevalence, besides being a chronic but preventable disease which can be caused depending on the consumption of certain nutritional elements interacting simultaneously with different factors, such as socioeconomic factors. Based on this problem, an analysis of a set of 189 dietary and demographic determinants is performed in this work, in order to find the relationship between these factors and the oral situation of a set of subjects. The oral situation refers to the presence and absence/restorations of caries. The methodology is performed constructing a dense artificial neural network (ANN), as a computer-aided diagnosis tool, looking for a generalized model that allows for classifying subjects. As validation, the classification model was evaluated through a statistical analysis based on a cross validation, calculating the accuracy, loss function, receiving operating characteristic (ROC) curve and area under the curve (AUC) parameters. The results obtained were statistically significant, obtaining an accuracy ≃ 0.69 and AUC values of 0.69 and 0.75. Based on these results, it is possible to conclude that the classification model developed through the deep ANN is able to classify subjects with absence of caries from subjects with presence or restorations with high accuracy, according to their demographic and dietary factors.

Pit and Fissure Sealants-A Comprehensive Review

Even in the 21st century, dental caries is considered a global burden, severely upsetting the health and quality of life of those affected. Apart from the usage of fluoride and regular oral hygiene, one of the most important prophylactic approaches against the occurrence of caries is the sealing of pits and fissures. However, the rapid progress of new materials and applications for sealing pits and fissures also raises new questions about their correct application. Recent literature on pit and fissure sealing, caries prevention, as well as caries risk assessment for both children and adults was reviewed. This report provides a general overview of pit and fissure sealing, the materials used for sealing occlusal surfaces, as well as indications and possible side effects. The conclusions are that sealing pit and fissures of primary and permanent teeth is an effective method for preventing and arresting caries. However, regular checkups must be conducted to avoid advanced tooth decay attributable to leakages in the sealing.

Effectiveness of Resin-Based Sealants with and without Fluoride Placed in a High Caries Risk Population: Multicentric 2-Year Randomized Clinical Trial

A split-mouth randomized clinical trial was carried out to assess the effectiveness of sealants in preventing carious ICDAS (International Caries Detection and Assessment System) 3–6 lesions within a 2-year follow-up. We evaluated the effectiveness of 2 types of resin-based sealants, with and without fluoride, their retention rates, and the caries risk factors related to their outcomes. The study included 663 tooth pairs in 400 children (aged 5–15 years) considered to be at high individual caries risk (ICR) and presenting permanent molars free of caries or affected by ICDAS 1–2 lesions. In the first randomization, molars were either randomized to the treatment group receiving a dental sealant or the control group (nontreatment), and in the second randomization the sealant material to be used in the intervention group was selected. Uni- and multivariate Cox proportional hazard models were employed. At the 2-year follow-up, 483 tooth pairs were assessed: sealed molars had 83% (adjusted HR = 0.17; 95% CI: 0.15–0.20) less risk of developing ICDAS 3–6 lesions than molars without sealant. The magnitude of the protective effect was lower among teeth with ICDAS 1–2 lesions or with occlusal deep fissures than without. If the total retention rate of sealants was 70% at 2 years, sealant loss was not associated with the risk of caries (HR = 1.29, 95% CI: 0.92–1.79, p = 0.14). Sealants allow the prevention of new ICDAS 3–6 lesions or progression of noncavitated carious lesions in children at high ICR, and the effect of the sealant was similar regardless of whether it contained fluoride or not.

Survival of extensive restorations in primary molars: 15-year practice-based study

BACKGROUND

Caries decline in the western world is accompanied by strong polarization among children; 8% of Finnish 5-year-olds having 76% of untreated caries. This high caries risk group needs preventive and restorative strategies.

AIM

To explore survival of extensive restorations in primary molars.

DESIGN

This study was based on health records from 2002 to 2016 of children under 18 years.

RESULTS

Of severely affected primary molars (n = 1061), 41% were restored with preformed metal crowns (PMCs), 38% with glass-ionomer cement (GIC)/polyacid-modified resin composite (PAMRC)/resin-modified GIC (RMGIC), and 21% with resin composites (RC). Younger children (3-8) received 97% of the PMCs and 86% of GIC/PAMRC/RMGIC; older ones (≥9) 91% of the RC restorations. Neither amalgam nor indirect restorations were registered. General dentists (GDs) engaged in primary care restored with GIC/PAMRC/RMGIC (52%) or RC (48%). GDs in general anesthesia care service placed 66% and specializing/specialized dentists 31% of PMCs. PMCs had lower failure rate (1.4% vs 3.0%) than GIC/PAMRC/RMGIC (P = 0.001). Choosing PMCs reduced patient visits compared to other restorations (P < 0.001).

CONCLUSIONS

Severely affected primary molars of children at high caries risk are better managed, using PMCs to optimize the resources in public oral health services.

Effect of risk-based payment model on caries inequalities in preschool children assessed by geo-mapping

Background

To describe, with aid of geo-mapping, the effects of a risk-based capitation model linked to caries-preventive guidelines on the polarization of caries in preschool children living in the Halland region of Sweden.

Methods

The new capitation model was implemented in 2013 in which more money was allocated to Public Dental Clinics surrounded by administrative parishes inhabited by children with increased caries risk, while a reduced capitation was allocated to those clinics with a low burden of high risk children. Regional geo-maps of caries risk based on caries prevalence, level of education and the families purchasing power were produced for 3-6-year-old children in 2010 (n = 10,583) and 2016 (n = 7574). Newly migrated children to the region (n = 344 in 2010 and n = 522 in 2016) were analyzed separately. A regional caries polarization index was calculated as the ratio between the maximum and minimum estimates of caries frequency on parish-level, based on a Bayesian hierarchical mapping model.

Results

Overall, the total caries prevalence (dmfs > 0) remained unchanged from 2010 (10.6%) to 2016 (10.5%). However, the polarization index decreased from 7.0 in 2010 to 5.6 in 2016. Newly arrived children born outside Sweden had around four times higher caries prevalence than their Swedish-born peers.

Conclusions

A risk-based capitation model could reduce the socio-economic inequalities in dental caries among preschool children living in Sweden. Although updated evidence-based caries-preventive guidelines were released, the total prevalence of caries on dentin surface level was unaffected 4 years after the implementation.

Practitioner evaluation of an online oral health and risk assessment tool for young patients

Aim To test the validity and acceptability of an online oral health assessment and biofeedback tool for young patients (under 17) for use in general dental practice.Methods A convenience sample of thirteen practitioners were recruited to test the functionality of a novel version of the Denplan PreViser Patient Assessment tool (DEPPA) developed for young patients (YDEPPA). Dentists who had completed eight or more assessments during a one month window were sent a link to an online feedback survey, comprising eight statements about YDEPPA, with scoring options of 0-10, where a score of 10 indicated complete agreement with the relevant questions. Verbatim comments were encouraged. The clinical data submitted were held in a central database in an encrypted format so that only the user practice could identify individual patients.Results Twelve practitioners completed eight or more assessments and were included in the survey. A total of 175 patient assessments were received. Ten practitioners completed the on-line survey. The statement 'YDEPPA produces a valid measurement of each patient's oral health' received an average feedback score of 8.8. The statement 'The full YDEPPA report is a valuable communication aid' received a score of 9.6. Feedback was generally very positive with all scores >8.2. Constructive critical feedback was received for the caries risk aspect of the YDEPPA protocol, with suggestions made for improving objectivity of data inputs. Eighty-one percent of the verbatim comments received were positive.Conclusions Once the caries risk issues raised by pilot dentists have been addressed, YDEPPA appears suitable as a pragmatic analytical and biofeedback tool for use in general dental practice to assess the oral health of young patients, and to facilitate education and engagement of young patients and their parents/carers in positive health behaviours.

Interprofessional oral health initiative in a nondental, American Indian setting

BACKGROUND AND PURPOSE

Tooth decay is the most common chronic childhood disease and American Indian (AI) children are at increased risk. Pediatric primary care providers are in an opportune position to reduce tooth decay. The purpose of this study was to integrate and evaluate a pediatric oral health project in an AI, pediatric primary care setting.

METHODS

The intervention set included caregiver education, caries risk assessment, and a same-day dental home referral. All caregiver/child dyads age birth to 5 years presenting to the pediatric clinic were eligible (n = 47).

CONCLUSIONS

Most children (n = 35, 91.1%) were scored as high risk for caries development. Of those with first tooth eruption (n = 36), ten had healthy teeth (27.8%) and seven had seen a dentist in the past 3 months (19.4%). All others were referred to a dentist (n = 29) and 21 families (72.4%) completed the referral.

IMPLICATIONS FOR PRACTICE

In fewer than 5 min per appointment (x = 4.73 min), the primary care provider integrated oral health screening, education, and referral into the well-child visit. Oral health is part of total health, and thus should be incorporated into routine well-child visits.

Pit and fissure sealants for preventing dental decay in permanent teeth

BACKGROUND

Dental sealants were introduced in the 1960s to help prevent dental caries, mainly in the pits and fissures of occlusal tooth surfaces. Sealants act to prevent bacteria growth that can lead to dental decay. Evidence suggests that fissure sealants are effective in preventing caries in children and adolescents compared to no sealants. Effectiveness may, however, be related to caries incidence level of the population. This is an update of a review published in 2004, 2008 and 2013.

OBJECTIVES

To compare the effects of different types of fissure sealants in preventing caries in occlusal surfaces of permanent teeth in children and adolescents.

SEARCH METHODS

Cochrane Oral Health's Information Specialist searched: Cochrane Oral Health's Trials Register (to 3 August 2016), the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2016, Issue 7), MEDLINE Ovid (1946 to 3 August 2016), and Embase Ovid (1980 to 3 August 2016). We searched ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform for ongoing trials to 3 August 2016. No restrictions were placed on language or date of publication.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing sealants with no sealant or a different type of sealant material for preventing caries of occlusal surfaces of premolar or molar teeth in children and adolescents aged up to 20 years. Studies required at least 12 months follow-up. We excluded studies that compared compomers to resins/composites.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened search results, extracted data and assessed risk of bias of included studies. We presented outcomes for caries or no caries on occlusal surfaces of permanent molar teeth as odds ratio (OR) or risk ratio (RR). We used mean difference (MD) for mean caries increment. All measures were presented with 95% confidence intervals (CI). We conducted meta-analyses using a random-effects model for comparisons where there were more than three trials; otherwise we used the fixed-effect model. We used GRADE methods to assess evidence quality.

MAIN RESULTS

We included 38 trials that involved a total of 7924 children; seven trials were new for this update (1693 participants). Fifteen trials evaluated the effects of resin-based sealant versus no sealant (3620 participants in 14 studies plus 575 tooth pairs in one study); three trials with evaluated glass ionomer sealant versus no sealant (905 participants); and 24 trials evaluated one type of sealant versus another (4146 participants). Children were aged from 5 to 16 years. Trials rarely reported background exposure to fluoride of trial participants or baseline caries prevalence. Resin-based sealant versus no sealant: second-, third- and fourth-generation resin-based sealants prevented caries in first permanent molars in children aged 5 to 10 years (at 24 months follow-up: OR 0.12, 95% CI 0.08 to 0.19, 7 trials (5 published in the 1970s; 2 in the 2010s), 1548 children randomised, 1322 children evaluated; moderate-quality evidence). If we were to assume that 16% of the control tooth surfaces were decayed during 24 months of follow-up (160 carious teeth per 1000), then applying a resin-based sealant would reduce the proportion of carious surfaces to 5.2% (95% CI 3.13% to 7.37%). Similarly, assuming that 40% of control tooth surfaces were decayed (400 carious teeth per 1000), then applying a resin-based sealant would reduce the proportion of carious surfaces to 6.25% (95% CI 3.84% to 9.63%). If 70% of control tooth surfaces were decayed, there would be 19% decayed surfaces in the sealant group (95% CI 12.3% to 27.2%). This caries-preventive effect was maintained at longer follow-up but evidence quality and quantity was reduced (e.g. at 48 to 54 months of follow-up: OR 0.21, 95% CI 0.16 to 0.28, 4 trials, 482 children evaluated; RR 0.24, 95% CI 0.12 to 0.45, 203 children evaluated). Although studies were generally well conducted, we assessed blinding of outcome assessment for caries at high risk of bias for all trials (blinding of outcome assessment is not possible in sealant studies because outcome assessors can see and identify sealant). Glass ionomer sealant versus no sealant: was evaluated by three studies. Results at 24 months were inconclusive (very low-quality evidence). One sealant versus another sealant: the relative effectiveness of different types of sealants is unknown (very low-quality evidence). We included 24 trials that directly compared two different sealant materials. Comparisons varied in terms of types of sealant assessed, outcome measures chosen and duration of follow-up. Adverse events: only four trials assessed adverse events. No adverse events were reported.

AUTHORS' CONCLUSIONS

Resin-based sealants applied on occlusal surfaces of permanent molars are effective for preventing caries in children and adolescents. Our review found moderate-quality evidence that resin-based sealants reduced caries by between 11% and 51% compared to no sealant, when measured at 24 months. Similar benefit was seen at timepoints up to 48 months; after longer follow-up, the quantity and quality of evidence was reduced. There was insufficient evidence to judge the effectiveness of glass ionomer sealant or the relative effectiveness of different types of sealants. Information on adverse effects was limited but none occurred where this was reported. Further research with long follow-up is needed.

Best clinical practice guidance for management of early caries lesions in children and young adults: an EAPD policy document

Scope and purposeThe guidance provides evidence- and clinically-based recommendations for detecting and diagnosing early/non-cavitated caries lesions, risk assessment and disease management.MethodologyThe guidance development is based on three reviews(1,2,3) and an interim seminar and workshop organised by the European Academy of Paediatric Dentistry in Brussels in May 2015.Review and updatingNo indication of a review or update schedule is given.RecommendationsSeven recommendations on caries detection and diagnosis, four recommendations on caries risk assessment and 11 on the management of the early carious lesion were made and they are briefly summarised in the table below.Research RecommendationsCaries detection and diagnosisThere is a need for more research in the primary dentition because most of the available studies consider only the permanent dentitionRadiograph subtraction studies need to be conductedOngoing evaluation of new methods and devicesThere is a need for well-designed prevention studies on early childhood caries which will provide sufficient and strong evidence of the cost-effectivenessThere is a significant need to bring the knowledge and learning to regular dental practice, to all the paediatric health care providers, the children and their parents.Caries risk assessmentClinical trials to assess the validity of models and single risk factors, as well as the role of confounding factors (eg age, lifestyle, socio-economy and socio-demography), for predicting caries.Further quantitative and qualitative health professional and parents would be helpful to identify perceptions and barriers to carrying out a CRA and to deliver a risk-based preventive care that could bridge the social inequalities in dental health.More research on the implementation of risk-based caries prevention and to establish the cost-effectiveness of such strategies.
