Gender differences in adolescents' perceptions toward dentists using the Japanese version of the dental beliefs survey: a cross-sectional survey.

BACKGROUND: While adult women show greater dental anxiety than adult men, few studies have examined gender differences in adolescent perceptions of dentists. Therefore, this cross-sectional study aimed to evaluate the gender differences in adolescents' perceptions toward dentists by using the Japanese version of the Dental Beliefs Survey (DBS) and the factor structure of the DBS. METHODS: We conducted surveys at schools, and 957 Japanese adolescents (403 girls and 554 boys, aged between 13 and 15 years) participated in this study. To assess their confidence in dentists, participants were asked to complete the self-reported, 15-item Japanese version of the DBS. We performed a Welch's t-test and a one-way analysis of variance to assess differences in DBS scores by gender and age. Factor analysis (principal components, varimax rotation) was used to assess the scale's factor structure. RESULTS: A significant gender difference was observed in the DBS scores (P = 0.018), suggesting that boys exhibit greater negative perceptions toward the behavior of dentists than girls. However, there was no significant difference found among ages. The factor analysis yielded two results: Factor 1, "trust" (seven items); and Factor 2, "lack of control" (five items). Notably, the factor structure differed according to gender. As such, by including only factors with eigenvalues above 1.0, the DBS for girls comprised "trust" (seven items) and "communication" (three items), while that for boys comprised "lack of control" (six items) and "belittlement" (six items). CONCLUSIONS: This study identified two factors of differing strengths pertaining to the confidence of Japanese adolescents in dentists. Gender differences in perceptions toward dentists were observed. Accounting for these differences may improve the effectiveness of strategies to lower dental anxiety and foster positive dental beliefs in young patients.

The Effect of Various Concentrations of Nitrous Oxide and Oxygen on the Hypersensitive Gag Reflex.

The purpose of this study was to compare the effectiveness of various concentrations of N2O/O2 on obtunding a hypersensitive gag reflex. We hypothesized that the administration of nitrous oxide and oxygen would obtund a hypersensitive gag reflex enough to allow a patient to tolerate the placement and holding of a digital x-ray sensor long enough to obtain a dental radiograph. Volunteers claiming to have a hypersensitive gag reflex were first screened to validate their claim and then tested by placing a size 2 digital x-ray sensor in the position for a periapical radiograph of the right mandibular molar area and holding it in place for 10 seconds. Subjects were first tested using room air only, then 30%, 50%, or 70% nitrous oxide until they were able to tolerate the sensor without gagging or discomfort. A visual analog scale was used for subjective responses, and other statistical tests were used to analyze the results. We found that for some subjects, 30% nitrous oxide was sufficient; for others, 50% was needed; and for the remainder of the subjects, 70% was sufficient to tolerate the test. Using a combination of 70% nitrous oxide and 30% oxygen allowed all patients claiming to have a hypersensitive gag reflex to tolerate the placement and holding of a digital x-ray sensor long enough to take a periapical radiograph.

Caregiver's education level and child's dental caries in African Americans: a path analytic study.

The objective of this study was to investigate the influence of caregiver education level on children's dental caries mediated by both caregiver and child oral health behaviors. Participants were 423 low-income African American kindergarteners and their caregivers who were part of a school-based randomized clinical trial. Path analysis tested the hypothesis that caregiver education level affected untreated dental caries and cumulative overall caries experience (decayed or filled teeth) through the mediating influence of frequency of dental visits, use of routine care, and frequency of toothbrushing for both the caregiver and the child. The results supported the hypothesis: caregivers who completed high school were 1.76 times more likely to visit dentists compared with those who did not complete high school (e(0.56) = 1.76, 95% CI: 1.03-2.99), which in turn was associated with 5.78 times greater odds of dental visits among their children (e(1.76) = 5.78, 95% CI: 3.53-9.48). Children's dental visits, subsequently, were associated with 26% fewer untreated decayed teeth compared with children without dental visits (e(-0.31) = 0.74, 95% CI: 0.60-0.91). However, this path was not present in the model with overall caries experience. Additionally, caregiver education level was directly associated with 34% less untreated decayed teeth (e(-0.42) = 0.66, 95% CI: 0.54-0.79) and 28% less decayed or filled teeth (e(-0.32) = 0.72, 95% CI: 0.60-0.88) among the children. This study overcomes important conceptual and analytic limitations in the existing literature. The findings confirm the role of caregiver education in child dental caries and indicate that caregiver's behavioral factors are important mediators of child oral health.

The effectiveness of xylitol in a school-based cluster-randomized clinical trial.

OBJECTIVE: The purpose of this double-blind, cluster-randomized clinical trial was to examine the effects of xylitol gummy bear snacks on dental caries progression in primary and permanent teeth of inner-city school children. METHODS: A total of 562 children aged 5-6 years were recruited from five elementary schools in East Cleveland, Ohio. Children were randomized by classroom to receive xylitol (7.8 g/day) or placebo (inulin fiber 20 g/day) gummy bears. Gummy bears were given three times per day for the 9-month kindergarten year within a supervised school environment. Children in both groups also received oral health education, toothbrush and fluoridated toothpaste, topical fluoride varnish treatment and dental sealants. The numbers of new decayed, missing, and filled surfaces for primary teeth (dmfs) and permanent teeth (DMFS) from baseline to the middle of 2nd grade (exit exam) were compared between the treatment (xylitol/placebo) groups using an optimally-weighted permutation test for cluster-randomized data. RESULTS: The mean new d(3-6)mfs at the exit exam was 5.0 ± 7.6 and 4.0 ± 6.5 for the xylitol and placebo group, respectively. Similarly, the mean new D(3-6)MFS was 0.38 ± 0.88 and 0.48 ± 1.39 for the xylitol and placebo group, respectively. The adjusted mean difference between the two groups was not statistically significant: new d(3-6)mfs: mean 0.4, 95% CI -0.25, 0.8), and new D(3-6)MFS: mean 0.16, 95% CI -0.16, 0.43. CONCLUSION: Xylitol consumption did not have additional benefit beyond other preventive measures. Caries progression in the permanent teeth of both groups was minimal, suggesting that other simultaneous prevention modalities may have masked the possible beneficial effects of xylitol in this trial.

School screening and parental reminders in increasing dental care for children in need: a retrospective cohort study.

OBJECTIVE: The objective of this study is to assess follow-up dental care received by children given baseline screening and referrals as part of an ongoing clinical trial. METHODS: A retrospective study with two cohorts of kindergarten children who had baseline and follow-up (9 months later) dental exams was used. The parents/caregivers of children with routine restorative or urgent needs at baseline received a referral letter and telephone reminders to seek care for their child. Children with referrals were evaluated at follow-up exam for the receipt of care. A baseline caregiver questionnaire provided information on the individual and family characteristics of the children. RESULTS: A total of 303 children had dental exams at both time periods. At baseline, 42 percent (126/303) received referrals and among the referred group19 percent (24/126) received follow-up care. A greater proportion with urgent referrals (10/30, 33 percent) received care than those with routine referrals (14/96, 15 percent). Baseline dmft decayed, missing, filled primary teeth and DMFT decayed, missing, filled permanent teeth was similar between children who did/did not receive follow-up care (P = 0.178 and 0.491, respectively). Children receiving referrals had caregivers with less education, higher Medicaid participation, fewer routine care visits, poorer self-rating of teeth, and a higher proportion of children reporting tooth pain. Children without receipt of follow-up care had caregivers who were more likely to report not visiting a dentist within the last 5 years and a greater number of missed days from work because of tooth problems. CONCLUSION: The rate of dental utilization was low even with school screening, referral and parental reminders among poor, largely minority inner-city kindergarten children.

Reliability and Validity of the Dental Anxiety Question Used With Children.

OBJECTIVE: Dental fear screening is an important part of providing a positive pediatric dental experience. To improve efficiency, the development of a single-item dental fear assessment tool for children has been desired. In this psychometric analysis, the reliability and validity of the Dental Anxiety Question (DAQ) is studied when used in children aged 7 to 18 years. METHODS: Participants completed the DAQ (pre-tx-DAQ), the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS), and a demographic information questionnaire before treatment. Participants repeated the DAQ after treatment (post-tx-DAQ) and once more at least 2 weeks later (follow-up-DAQ). Stability reliability within the DAQ scores and criterion validity with the CFSS-DS were evaluated. RESULTS: Stability reliability analyses between pre-tx-DAQ/post-tx-DAQ and post-tx-DAQ/follow-up-DAQ demonstrated significant positive correlations: Spearman rank correlation coefficient (rs) = 0.420, rs2 = 0.18, P < .001, and rs = 0.563, rs2 = 0.32, P < .001, respectively. Criterion validity analysis between the pre-tx-DAQ and CFSS-DS also demonstrated a significant correlation: Pearson correlation coefficient (r) = 0.584, r2 = 0.34, P < .001. CONCLUSION: The stability reliability and criterion validity of the DAQ was proved among children.

Thinking about going to the dentist: a Contemplation Ladder to assess dentally-avoidant individuals' readiness to go to a dentist.

BACKGROUND: The Transtheoretical Model suggests that individuals vary according to their readiness to change behavior. Previous work in smoking cessation and other health areas suggests that interventions are more successful when they are tailored to an individual's stage of change with regards to the specific behavior. We report on the performance of a single-item measure ("Ladder") to assess the readiness to change dental-avoidant behavior. METHODS: An existing Contemplation Ladder for assessing stage of change in smoking cessation was modified to assess readiness to go to a dentist. The resulting Ladder was administered to samples of English-speaking adolescents (USA), Spanish-speaking adults (USA), and Norwegian military recruits (Norway) in order to assess construct validity. The Ladder was also administered to a sample of English-speaking avoidant adolescents and young adults who were enrolled in an intervention study (USA) in order to assess criterion validity. All participants also had dental examinations, and completed other questionnaires. Correlations, chi square, t tests and one-way ANOVAs were used to assess relationships between variables. RESULTS: In two samples, participants who do not go to the dentist had significantly more teeth with caries; in a third sample, participants who do not go to the dentist had significantly worse caries. Ladder scores were not significantly related to age, gender, caries, or dental fear. However, Ladder scores were significantly related to statements of intention to visit a dentist in the future and the importance of oral health. In a preliminary finding, Ladder scores at baseline also predicted whether or not the participants decided to go to a dentist in the intervention sample. CONCLUSIONS: The data provide support for the convergent and divergent construct validity of the Ladder, and preliminary support for its criterion validity. The lack of relationship between dental fear and Ladder scores suggests that avoidant individuals may be helped to decide to go to a dentist using interventions which do not explicitly target their fear.

Oral Health Policies to Tackle the Burden of Early Childhood Caries: A Review of 14 Countries/Regions.

Aim: Early childhood caries (ECC) has significant public health implications but has received inadequate global attention. There is limited information regarding the success of oral health policies implemented to address the challenges of ECC. This review aimed to summarize such policies to tackle ECC from different countries/regions. Method: Independent collaborators from 14 countries/regions (Australia, Brazil, Cambodia, China, Hong Kong, Egypt, India, Indonesia, Japan, Nigeria, Thailand, UK, USA, and Venezuela) collected the data. The ECC status, dental workforce, oral health policies on ECC prevention in different countries/regions were summarized by each country. Results: The findings indicated that ECC prevalence varied in different countries/regions. The lowest prevalence of ECC among 5-year-old children was found in Nigeria (7%), and the highest was found in Indonesia (90%). The existing dental workforce and resources are limited in most countries. The smallest dentist to population ratio was reported by Nigeria at 1:48,400, whereas the highest ratio was in Brazil (1:600). Out of 14, three (21%) countries namely India, Venezuela and Cambodia had no national oral health policies addressing ECC and four (29%) countries (Cambodia, China, India, Venezuela) had no publicly funded dental care program for 0-5-year-old children. Water fluoridation is available in four countries/regions (Australia, Brazil, Hong Kong, USA). Conclusion: ECC remains a global health challenge and dental workforce is limited. National/regional programs to tackle ECC are not yet prioritized in many countries/regions. Evidence to support demonstration projects is limited. Further research on the cost-effectiveness of interventions strategies is required for policymakers.

Acceptability and Demand of Therapy Dog Support Among Oral Health Care Providers and Caregivers of Pediatric Patients.

Purpose: This cross-sectional study evaluated the acceptability and demand for therapy dog support in pediatric dentistry (TDSPD). Methods: Caregiver surveys measured acceptability and demand for TDSPD using a five-point Likert scale (one equals "not at all", five equals "very much"). Provider surveys measured acceptability for TDSPD using a five-point Likert scale. Scores of four or five were regarded as positive. Surveys were administered in the pediatric dental clinic at Case Western Reserve University, Cleveland, Ohio. Results: The mean±SD of acceptability and demand from the caregiver survey was 4.67±0.96 and 3.86±1.61, respectively. Ninety percent (n equals 174) of caregivers indicated acceptability for TDSPD to support their child. Sixty-eight percent (n equals 130) of caregivers indicated demand for TDSPD. The mean±SD of acceptability from the provider survey was 3.63±1.50. Sixty-two percent (n equals 47) of provider survey respondents accepted the overall integration of therapy dogs to support patients. Thematic analysis of the qualitative provider responses yielded concerns for risk of accident (36 percent), infection control (50 percent), and clinic efficiency (33 percent). Caregiver survey qualitative responses were positive (68 percent), with respondents also sharing concerns for efficiency and zoonosis. Conclusions: Responses support the acceptability of and demand for therapy dog support in pediatric dentistry.

Expanded studies of the pharmacokinetics and clinical effects of multidose sublingual triazolam in healthy volunteers.

Previous work described the pharmacokinetics and clinical effects of multidose sublingual triazolam (Halcion; Pharmacia & Upjohn Co, Kalamazoo, Mich). This laboratory study evaluated the hypothesis that incremental dosing of triazolam produces dose-dependent central nervous system depression that is profound and long lasting. Forty-nine healthy adults between the ages of 21 and 39 years, not receiving dental treatment, were randomly assigned to placebo (n = 12) or 1 of 3 triazolam groups (0.25-mg single dose, n = 12; 0.5 mg divided between 2 equal doses for 60 minutes, n = 12; or 0.75 mg divided among 3 doses for 90 minutes, n = 13). Plasma triazolam concentrations were determined. Bispectral index (BIS) and the Observer Assessment of Alertness/Sedation scale were used to assess sedation. Plasma triazolam concentrations increased with time in all subjects, with Tmax and Cmax both increasing dose dependently. Compared with placebo, all dosing paradigms produced dose-dependent BIS suppression and sedation. The single dose of 0.25 mg reached its peak BIS suppression at 90 (81 +/- 7) minutes and sedation at 120 (3.6 +/- 0.5) minutes and returned to baseline before 360 minutes. In contrast, incremental dosing of 0.5 and 0.75 mg produced profound and long-lasting BIS suppression and sedation that did not plateau until either 180 or 210 minutes as measured by the BIS index (67 +/- 14 and 60 +/- 16 at 0.5 and 0.75 mg, respectively) and 150 minutes as measured by the Observer Assessment of Alertness/Sedation scale (3.2 +/- 1.0 and 2.7 +/- 0.4 at 0.5 and 0.75 mg, respectively). These data more fully characterize the effects of incremental dosing with sublingual triazolam and provide additional insight for discharge safety recommendations.

The Dental Neglect Scale in adolescents.

BACKGROUND: Dental neglect has been found to be related to poor oral health, a tendency not to have had routine check-ups, and a longer period of time since the last dental appointment in samples of children and adults. The Dental Neglect Scale (DNS) has been found to be a valid measure of dental neglect in samples of children and adults, and may be valid for adolescents as well. We administered the DNS to a sample of adolescents and report on the relationships between the DNS and oral health status, whether or not the adolescent has been to the dentist recently for routine check-ups, and whether or not the adolescent currently goes to a dentist. We also report the internal and test-retest reliabilities of the DNS in this sample, as well as the results of an exploratory factor analysis. METHODS: One hundred seventeen adolescents from seven youth groups in the Seattle-Tacoma metropolitan area (Washington State, U.S.) completed the DNS and indicated whether they currently go to a dentist, while parents indicated whether the adolescent had a check-up in the previous three years. Adolescents also received a dental screening. Sixty six adolescents completed the questionnaire twice. T-tests were used to compare DNS scores of adolescents who have visible caries or not, adolescents who have had a check-up in the past three years or not, and adolescents who currently go to a dentist or not. Internal reliability was measured by Cronbach's alpha, and test-rest reliability was measured by intra-class correlation. Factor analysis (Varimax rotation) was used to examine the factor structure. RESULTS: In each comparison, significantly higher DNS scores were observed in adolescents with visible caries, who have not had a check-up in the past three years, or who do not go to a dentist (all p values < 0.05). The test-retest reliability of the DNS was high (ICC = 0.81), and its internal reliability was acceptable (Cronbach's alpha = 0.60). Factor analysis yielded two factors, characterized by home care and visiting a dentist. CONCLUSION: The DNS appears to operate similarly in this sample of adolescents as it has in other samples of children and adults.

Prevention of Dental Caries by Silver Diamine Fluoride.

The use of silver diamine fluoride (SDF) for management of dental caries has gained considerable attention due to recent regulatory clearance in the United States. The primary focus of policies, presentations, and publications has been the arrest of caries lesions (cavities) because of the material's unique ability to non-invasively achieve this elusive and clinically important goal. However, SDF also has proven efficacy in prevention, ie, decreasing the incidence of new caries lesions. Analysis of nine clinical trials in children shows that SDF prevented 61% of new lesions compared to controls. To prevent one new caries lesion, clinicians need to treat four primary teeth (one patient) or 12.1 permanent molars (three patients) with SDF. The preventive effect appears to be immediate and maintains at the same fraction over time. Direct comparisons of SDF applied once per year with alternative treatments show that SDF is more effective than other topical fluorides placed two to four times per year and more cost-effective than dental sealants. Enamel lesions may be even more responsive than cavitated dentin lesions. Annual application of SDF to high-risk surfaces (eg, mesial surfaces of permanent first molars where the distal surface of the second primary molar is carious) in patients with any risk of new caries lesions appears to be the most cost-effective approach available to prevent dental caries. SDF is an underutilized evidence-based preventive agent for dental caries.

Research productivity of members of IADR Behavioral Sciences and Health Services Research Group: relationship to professional and personal factors.

This report describes the research productivity of the members of the International Association for Dental Research (IADR) Behavioral Sciences and Health Services Research Group and examines personal and professional factors related to greater productivity. The findings from previous studies suggested there might be gender discrimination in opportunities for women faculty. Members on the active membership list for this IADR group were surveyed by email. Most were dentists, and three-quarters had external funding for their research. The primary outcome measure was the number of self-reported published articles in PubMed in the preceding twenty-four months. The mean number of these publications was 4.9 (SD=5.1). Gender and time in research were the best predictors of research productivity of this population. There was no difference in time for research between the men and women in this study. Controlling for gender, the best single predictor of research productivity remained percent time spent in research. Overall, the members of the IADR group spent almost three times as much time in research and were more than twice as productive as faculty members as a whole as described in earlier studies. In view of the current emphasis in many countries on addressing the social and behavioral determinants of oral health disparities, the productivity of this area of dental research is very important. Trends toward clinically oriented, non-research-intensive dental schools in the United States and reductions in time and funding available to conduct research should be of concern.

Oral health and medical conditions among Amish children.

BACKGROUND: The Amish are a growing population who live a traditional, rural way of life, which makes them less accepting of modernism. Most Amish live in poverty and are detached from modern health care. In addition, the recent change of their lifestyle has been reported, such as consuming a nontraditional diet and the usage of electronic devices. As a result, their lifestyle change may have impacted their oral health. However, since only a single report about oral health among Amish children has been published approximately three decades ago it has not yet been updated. This study describes oral health among Amish children and their medical conditions during visits to a mobile dental unit (MDU). MATERIAL AND METHODS: The dental records of all patients (N=216) who visited a mobile dental unit were reviewed, which covers 1 year from May 20, 2011, the first date of service. The following factors were taken into consideration during the review process: parental perceptions of their children's oral health care, dental care experiences, and general health information. RESULTS: Fifty-four (27.8%) children, ages 3 to 17, have never received dental treatment before visiting the MDU; the average number of untreated decayed teeth was 6.8. In spite of this, most parents rated their children's oral health as good or very good (87.7%). The high cost and long distance travel associated with routine, professional dental care makes it difficult for children to maintain good oral hygiene. Our analysis revealed that bleeding disorders were more prevalent among this gene pool compared to the nation at large; however, asthma was less common. CONCLUSIONS: There are oral and general health disparities among Amish children. There is a lack of awareness among Amish parents with regard to their children's oral health. Key words:Amish, child, dental caries, mobile health units.

The effect of social geographic factors on the untreated tooth decay among head start children.

BACKGROUND: Disparities among untreated dental caries exist for children from low-income families in the United States. Understanding of the mechanism of the disparities is required to reduce it and social geographic factors are one of the important influences. Although the effect of fluoridated water has been well reported, studies of other sociogeograpic factors, such as the density of available dentists, are still very limited. The objective of this study is to explore the effect of sociogeographic factors on the number of primary teeth with untreated dental caries among children from low-income families who are enrolled in Head Start programs throughout Northeast Ohio of the United States. MATERIAL AND METHODS: This was a cross-sectional chart review study. Three hundred-eighty-eight charts were reviewed, and the number of primary teeth with untreated dental caries (dt) and the children's addresses were retrieved. The sociogeographic variables, including fluoridated water availability and the density of available dentists who accept a government-supported insurance (Medicaid dentists), were collected. RESULTS: The mean (standard deviation) of children's age was 3.51 (1.14) years with a range of 7 months to 5 years. A negative binomial regression model analysis, which used dt as a dependent variable and children's characteristic factors (i.e. age, gender, insurance type, and total number of primary teeth) and sociogeographic factors (i.e. Population, total number of Medicaid dentists, density of Medicaid dentist, and Fluoride water availability) of cities, as independent variables, demonstrated that only the density of Medicaid dentist in the sociogeographic factors indicated a significant effect (Estimated ß-Coefficients (Standard Errors)=-0.003 (0.002), p=0.030). CONCLUSIONS: This study demonstrated a significant negative association between the density of available dentists and untreated dental caries among children from low-income families in Head Start programs in Northeast Ohio. Increasing available dentists may be a strategy to reduce the number of early childhood caries. Key words:Child, poverty, dental caries, Health Services Accessibility.

A mediation analysis study: The influence of mothers' dental anxiety on children's dental utilization among low-income African Americans.

OBJECTIVES: The aim of this study was to test a hypothesized mediation model to explain associations between mothers' dental anxiety and children's dental utilization through the mothers' own dental utilization. METHODS: Two hundred and fourteen low-income African American mothers with young children (age 31-59 months) completed a study questionnaire which assessed (i) mothers' dental anxiety; (ii) mothers' dental utilization (seeing a dentist at least once a year) and (iii) children's dental utilization (at least one non-study-related dental visit during the 36-month study period). The hypothesized mediation model consisted of these three elements with both a direct path from mothers' dental anxiety to children's dental utilization and an indirect path from mothers' dental anxiety to children's dental utilization through mothers' dental utilization. Mediation analysis with bootstrapping was conducted to test the hypothesized model. RESULTS: The mediation analysis indicated significant total effect of mothers' dental anxiety on children's dental utilization. The standardized total effect of mothers' anxiety on children's dental utilization was -0.172 (SE=.084, P=.041), and the standardized indirect effect of mothers' anxiety on children's dental utilization mediated by mothers' dental utilization was -0.069 (SE=.039, P=.076). The direct effect from mothers' anxiety to children's dental utilization was not statistically significant (P=.261) after adjusting for the mothers' dental utilization. CONCLUSIONS: In this low-income African American sample, there was a trend for mothers' dental anxiety to be associated with children's dental utilization indirectly through mothers' own dental utilization, while the direct influence of mothers' dental anxiety on children's dental utilization was not seen. This suggests that mothers' dental utilization might explain how mothers' dental anxiety impacts children's early dental utilization.

Dental fear among transgender individuals - a cross-sectional survey.

AIMS: The aims of this study were to: (1) evaluate the level of dental fear among transgender individuals and (2) investigate specific predictors of dental fear in individuals who identify as transgender. METHOD AND RESULTS: An anonymous survey among transgender adults was conducted using both a web-based and paper survey. The survey included the Dental Fear Survey (DFS), history of hormonal interventions, perceived gender roles, and demographic information. The bivariate analyses did not show a significant difference in DFS between sex assigned at birth (p = 0.628) or among gender identities (p = 0.109). A regression model analysis for the level of DFS by using participants' demographic information as independent variables indicated the fear and experience of discrimination/maltreatment were significant predictors of dental fear; standardized beta coefficients (p-value) were 0.35 (p = 0.017) and 0.28 (p = 0.041), respectively. CONCLUSION: The fear and experiences of discrimination/maltreatment were significantly positively associated with their level of dental fear.

"Dentists' and dietitians' recommendations of snacks and dental caries experience among kindergarteners".

BACKGROUND: Parents receive diet recommendations for their children from dentists and dietitians, but a conflict of diet suggestions has been reported. This research was conducted to investigate dental caries experiences in children consuming snacks that were recommended by dentists and/or dietitians. MATERIAL AND METHODS: A total of 442 kindergarteners under went dental examinations, and their caregivers filled out questionnaires. Snacks were sorted by name. Three dentists and three dietitians determined whether they would recommend these snacks. The snacks were divided into four categories: snacks recommended by both groups, snacks recommended by neither, snacks recommended only by dentists, and snacks recommend only by dieticians. Children were assigned to particular groups based on their primary snack consumption. The children's caries experiences (dft) were compared among the four groups. RESULTS: The agreement level on the recommended snacks between dietitians and dentists was moderate (Kappa=0.43). Thirty-nine snacks were identified; 13 recommended by neither, 4 recommended by dietitians, 7 were recommended only by dentists, and 15 were recommended by both. The mean (standard deviation) of dft amongthe children was 4.66 (3.81), 2.66 (3.17), 3.21 (3.37), and 4.02 (4.02), and respectively. The ANOVA and Tukey post-hoc tests indicated that children who consumed snacks recommended only by one professional, dietitian or dentist, have significantly fewer dental caries than children who consumed snacks recommended by neither professional. (ANOVA: F=4.494, p=0.004, Tukey post-hoc test: p=0.007 and p=0.046, respectively). CONCLUSIONS: Dentists can recommend snacks that are nutrient dense, even though it contains sucrose. Key words:Child, dental caries, snacks, dentist, nutritionists.
