Preventive dental care utilization and dental caries for Medicaid-enrolled adolescents in Oregon.

This study aimed to evaluate the relationship between preventive dental care utilization and untreated dental caries for Medicaid-enrolled adolescents and to determine if the relationship is moderated by chronic conditions (CC). This analysis was based on 2015-2016 Medicaid claims files and survey data collected from adolescents ages 12-18 years enrolled in Oregon Medicaid, who received a dental screening between December 2015 and December 2016 (n = 240). To assess the relationship between preventive dental care utilization and untreated dental caries (defined as decayed tooth surfaces), prevalence ratios (PR) and 95% confidence intervals (CI) were generated using log-linear regression models. We also tested for an interaction between preventive dental care utilization and CC. About 60.4% of adolescents utilized preventive dental care, 21.7% had CC, and 29.6% had ≥1 decayed tooth surfaces. There were no significant differences in untreated dental caries between adolescents who did and did not utilize preventive dental care (PR: 0.73, 95% CI: 0.33-1.60; p = 0.43). There was not a significant interaction between preventive dental care utilization and CC (p = 0.65). Preventive dental care utilization was not significantly associated with untreated dental caries for adolescents with CC (PR: 0.51, 95% CI: 0.10-2.65; p = 0.42) nor among adolescents without CC (PR: 0.79, 95% CI: 0.33-1.91; p = 0.61). Preventive dental care was not shown to be associated with lower untreated dental caries for Medicaid-enrolled adolescents or those with CC. Future work that is adequately powered should continue to elucidate this relationship in Medicaid enrollees.

Silver Diamine Fluoride: A Review

BACKGROUND The burden of untreated dental caries among African children is high. Silver diamine fluoride (SDF) is a simple, non- technique sensitive intervention to stop the progression of active untreated carious lesion in primary teeth among children. Silver diamine fluoride (SDF) 38% solution contains 44,800 ppm fluoride ions and its stains teeth after use. 
 METHOD An electronic literature search in Web of science, Scopus, PubMed, Google Scholar, African journal online, Researchgate and Google was done in May,2023. Search terms and keywords were combined by Boolean operators. Two independent investigators (research assistants) screened titles, abstracts and full text of publications. The inclusion criteria were original research articles, case report, case series related to silver diamine fluoride ( human studies) conducted in African region and in electronic databases.
 RESULTS Ten articles were included as they were assessed to meet the aim of the review. The study design of the articles were four invitro studies, three randomized controlled clinical trial, one randomized clinical trial, one split-mouth, self-controlled clinical trial and one split-mouth, randomized controlled clinical study. 90 % of the studies identified was conducted in Egypt, while 10 % of the studies was conducted in Nigeria.
 CONCLUSION Studies on silver diamine fluoride (SDF) identified in African countries were few and restricted to few countries. Silver diamine fluoride can be used as an intervention for active and progressing untreated carious lesion in primary teeth among children though it stains teeth after use. More studies from the diverse ethnic population in Africa will contribute to the existing literature.

Which dental and psychosocial factors may predict bullying occurrence in adolescence?

Cohort study. 639 preschool children at baseline (T1) and 429 adolescents at follow-up (T2). Oral health conditions (untreated dental caries, dental trauma and malocclusion, sense of coherence (SOC), self-perception of dental treatment needs, general and dental bullying. Chi-square test, t-test, structural equation modeling, goodness of fit. Untreated dental caries and low socioeconomic status impacted the occurrence of both general and dental bullying. SOC and self-perceived dental treatment need were also important factors in the occurrence of bullying. The oral health condition that most impacted bullying episodes both directly and indirectly was untreated dental caries. Socioeconomic status was also an important cumulative predictor of the occurrence of episodes of bullying.

Association between sleep duration and dental caries in a nationally representative U.S. population

BackgroundDental caries is considered one of the most prevalent chronic diseases worldwide despite all dental public health efforts. Short sleep duration has been established as a risk factor for several medical conditions. In this study, we aimed to examine the relationship between sleep duration and dental caries.MethodsData were collected from the 2017–2018 cycle of the National Health and Nutrition Examination Survey, a nationally representative health survey conducted in the United States. Participants who completed sleep questionnaires were examined by dentists using standardized clinical criteria. Analysis was limited to Individuals aged ≥ 16 years with complete clinical oral examination data and who completed the sleep questionnaire (N = 5,205). The data were weighted to provide a national estimate, and multiple potential covariates were included in the analysis to account for the complex sample design. The main outcomes of the study were untreated dental caries and dental caries experience. The main predictor variables were average sleep hours/night and a binary variable with 7 h/night as a cut off. Multiple weighted Poisson and logistic regression analyses were conducted to test the hypothesis that people with short sleep duration are more likely to exhibit dental caries.ResultsThis study showed a statistically significant negative relationship between sleep duration and dental caries amongst all weighted adjusted analyses conducted. For a one hour increase in average sleep hours, the Adjusted Odds Ratio (AOR) of having a dental caries experience might decrease by 0.86 (AOR = 0.86, 95% CI = 0.75–0.98, P < 0.05). Individuals who reported an average sleep of ≥ 7 h were less likely to have a dental caries experience compared to individuals who reported an average sleep of < 7 h (AOR = 0.52, 95% CI = 0.33–0.82, P < 0.05). For a one hour increase in average sleep hours, the Adjusted Mean Ratio (AMR) of having a dental caries experience might decrease by 0.97 (AMR = 0.97, 95% CI = 0.96–0.99, P < 0.05), and was lower for those who reported sleeping ≥ 7 h/night than individuals who reported sleeping < 7 h/night (AMR = 0.92, 95% CI = 0.87–0.99, P < 0.05).ConclusionFindings of this cross-sectional representative study of the U.S. population revealed a statistically significant negative association between sleep duration and dental caries. In this study, individuals who slept < 7 h/night were more likely to exhibit dental caries.

The oral health of adults attending dental practices in England in 2018: a report of a novel method and findings.

Introduction National surveys of the oral health of adults are conducted decennially. For reasons of feasibility and cost, these only provide accurate information at large geographical areas. To address this, a survey of adults attending dental practices in England was undertaken.Aim To describe and discuss the survey method and findings.Method A clinical examination and questionnaire survey was conducted in a sample of English dental practices.Results Questionnaires (n = 16,572) and clinical examinations (n = 14,270) were completed with patients from 1,173 dental practices. Poorer oral health disproportionately affected older adults and those from more socioeconomically deprived areas. Over one in three from more deprived areas had untreated caries compared with one in five in the less deprived (36.2% vs 19.9%) and impacts of oral problems were nearly three times higher in the more deprived areas (27.9% vs 11.0%). Of those receiving NHS care, 28.7% and 46.2% reported they would struggle/be unable to pay a Band 2 and Band 3 NHS patient charge, respectively.Conclusion It is feasible to undertake a survey of adults in dental practices but care must be taken generalising the findings to the general population and comparing them with other surveys undertaken using different methods.

Role of Resistin in Various Diseases with Special Emphasis on Periodontal and Periapical Inflammation - A Review.

Resistin is a small adipocyte-specific secretory hormone molecule. It has been associated with a number of cellular and metabolic processes. It has also been essentially implicated to have a vital role in the interplay between insulin resistance, obesity, and type II diabetes. Numerous clinical studies have demonstrated an association between many pathological illnesses with elevated serum resistin levels. It has also been shown to affect and modulate various molecular processes such as atherosclerosis, cancer cell metabolism, and inflammation. Periodontitis is a widespread inflammatory disease affecting human beings. Periapical periodontitis is an inflammatory disease that manifests as a sequela of untreated dental caries. Therefore, in this article, we summarize the divergent physiological roles played by resistin and its association with the mechanism of various pathologies. Moreover, current scientific studies discussing its association and role in common dental pathologies, periodontitis, and apical periodontitis are reviewed.

The Prevalence and Severity of Dental Caries Among Pregnant Women in the State of Rio de Janeiro, Brazil.

To assess in a pilot study the prevalence and severity of dental caries among pregnant women compared to non-pregnant women in the state of Rio de Janeiro, Brazil. A cross-sectional, observational study was conducted. Data collection consisted of clinical examinations and general questionnaires concerning oral hygiene habits and recent dental visits of pregnant and non-pregnant women. Prevalence and severity of caries was determined by the CAST index and the CAST severity score. Permission for this study was granted by the National Research Ethics Commission of Brazil. Written informed consent was obtained from all participants. In total, 67 pregnant women were included (mean age (SD) 25.5 ± 5.4 years) and 79 non-pregnant women (26.0 ± 5.3 years). Mean number of teeth with untreated caries (CAST 4-7) among pregnant women was significantly lower (1.2 ± 1.8) compared to non-pregnant women (2.7 ± 4.0; Mann-Whitney test, p = 0.027). In both groups, 40-60% were in need of curative treatment. There was no significant difference between the two groups in frequency of dental visits (p > 0.05), but pregnant women brushed their teeth more often (Mann-Whitney test, p < 0.001). Pregnant women in the state of Rio de Janeiro have fewer untreated caries and less severe dental caries compared to non-pregnant women. Still, half of all women in this study are in need of curative treatment for at least one tooth. Effective preventive programs should therefore be developed to stimulate preventive oral care among all women.

Pathways between verbal bullying and oral conditions among school children.

To investigate the direct and indirect pathways between verbal bullying and adverse oral conditions among school-aged children. A cross-sectional survey was conducted with 8- to 10-year-old children, enrolled in public schools in Southern Brazil. Verbal bullying was collected by self-reports. Independent variables included sociodemographic characteristics (sex, age, household income, and caregivers' educational level) and oral conditions (anterior open bite, anterior teeth crowding, upper anterior diastema, large overjet, untreated dental caries, and PUFA index). The pathways between verbal bullying and the independent variables were analysed through structural equation modelling. 1369 children were included. The prevalence of verbal bullying was 26.2% (95% confidence interval [CI] 23.9-28.6%). Verbal bullying was directly influenced by large overjet (standard coefficient [SC] 0.13, P < 0.01), untreated dental caries (SC 0.63, P = 0.01) and PUFA index (SC 0.75, P = 0.02). Sex (SC -0.005, P = .04) and age (SC -0.006, P < 0.01) indirectly influenced verbal bullying via untreated dental caries. Verbal bullying was directly influenced by large overjet, untreated dental caries and PUFA index. Sex and age indirectly impacted verbal bullying through untreated dental caries.

Association of Interdental Cleaning and Untreated Root Caries in Adults in the United States of America

PurposeThis study aimed to evaluate the association between interdental cleaning and untreated root caries amongst middle-aged and older adults in the US. Materials and methodsData were obtained from the National Health and Nutrition Examination Survey (NHANES) (2015–2016 and 2017–2018). Adults aged ≥40 years who underwent full mouth examination and root caries assessment were included. Participants were classified based on their interdental cleaning frequency as none, 1–3 d/wk, and 4–7 d/wk. Associations between interdental cleaning and untreated root caries were assessed using a weighted multivariable logistic regression model adjusted for sociodemographics, general behaviour, general health condition, oral conditions, oral health behavior, and dietary factors. Subgroup analyses stratified by age and sex were performed after adjusting for covariates in the logistic regression models. ResultsThe prevalence of untreated root caries was 15.3% amongst 6217 participants. Interdental cleaning for 4–7 d/wk was a significant risk factor (odds ratio, 0.67; 95% confidence interval, 0.52–0.85). It was associated with a 40% reduction in the risk of untreated root caries in participants aged 40 to 64 years and a 37% reduction in women. Untreated root caries was also significantly associated with age, family income, smoking status, root restoration, number of teeth, untreated coronal caries, and recent dental visit. ConclusionsInterdental cleaning for 4–7 d/wk was associated with fewer untreated root caries amongst middle-aged adults and women in the US. The risk of root caries increases with age. Low family income was a risk indicator for root caries amongst middle-aged adults. Additionally, smoking, root restoration, number of teeth, untreated coronal caries, and recent dental visits were common risk factors for root caries in middle-aged and older people in the US.

Social support and oral health among working-age and older adults in the United States.

The purpose of this study was to examine the association of social support with untreated dental caries and severe tooth loss in adults in the United States. This cross-sectional study was conducted by analyzing data obtained from 5,447 individuals, 40 years of age and older, in the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2008 who had both a complete dental examination and social support index measures. Sample characteristics, overall and by social support level, were examined through descriptive statistical analyses. Logistic regression analyses were performed to estimate the association of social support with untreated dental caries and severe tooth loss. In this nationally representative sample (mean age 56.5 years) the prevalence of low social support was 27.5%. The prevalence of individuals with moderate-to-high social support increased with higher levels of educational attainment and income level. In fully adjusted models, relative to those who had moderate-high social support levels, individuals with low social support had 1.49 higher odds of untreated dental caries (95% CI, 1.17-1.90, p=0.002) and 1.23 higher odds of severe tooth loss (95% CI, 1.05-1.44, p=0.011). Higher odds of untreated dental caries and severe tooth loss were found among U.S. adults with low levels of social support compared to those with moderate-to-high levels of social support. Additional studies are warranted to provide a more current perspective on the impact of social support on oral health so that programs may be developed and tailored to reach these populations.

Does using the sociodental approach in oral health care influence use of dental services and oral health of adolescents living in deprived communities? a one-year follow up study

BackgroundOral health needs assessment is important for oral health care planning. This study compared dental treatment needs between normative and sociodental needs. We also longitudinally examined the relationships of baseline sociodental needs measures and socioeconomic status with one-year follow up measures of use of dental services, dental caries, filled teeth, and oral health-related quality of life (OHRQoL).MethodsA prospective study was conducted with 12-year-old adolescents from public schools in deprived communities in the city of Manaus, Brazil. Validated questionnaires were used to collect adolescents’ sex and socioeconomic status, OHRQoL (CPQ11 − 14) and behaviours (sugar intake, frequency of toothbrushing, regular use of fluoridated toothpaste and pattern of dental attendance). Normative need was assessed according to decayed teeth, clinical consequences of untreated dental caries, malocclusion, dental trauma, and dental calculus. The relationships between variables were tested thorough Structural equation modelling.ResultsOverall 95.5% of adolescents had normative dental treatment needs. Of these, 9.4% were classified as high level of propensity. Higher normative/impact need and greater propensity-related need directly predicted use of dental services at one-year follow up. The latter mediated the association of normative/impact need and propensity-related need with incidence of dental caries and filled teeth. Normative/impact need and use of dental services were directly associated with filled teeth at one-year follow up. Poor OHRQoL at one-year follow-up was directly predicted by higher normative/impact need at baseline and less filled teeth at one-year follow up. Greater socioeconomic status was directly associated with better propensity-related need. Socioeconomic status indirectly predicted incidence of dental caries and filled teeth via propensity-related need and use of dental services.ConclusionsSociodental needs measures were related to use of dental services, dental caries, filled teeth and OHRQoL after one year among adolescents living in deprived communities. Adolescents with dental needs treatment priorities according to the sociodental approach had more filled teeth via use of dental services. Dental services utilisation did not attenuate the impact of normative and impact-related need on dental caries incidence and poor OHRQoL after one year. Our findings suggest the importance of developing oral health promotion and enhancing access to dental care to improve oral health of adolescents living in deprived communities.

Untreated dental caries among Libyan children during and after the war and in internally displaced person camps.

The present study assessed whether living in a conflict zone and in internally displaced person (IDP) camps were associated with the number of untreated caries in primary, permanent and all teeth in Libyan children and whether these associations differed by parents' educational attainment. Cross-sectional studies were conducted in Benghazi, Libya, in 2016/2017 during the war and in 2022 after the war including children in schools and in IDP camps in the same setting. Self-administered questionnaires and clinical examinations were used for data collection from primary schoolchildren. The questionnaire collected information on children's date of birth, sex, level of parental education and school type. The children were also asked to report on how often they consumed sugary drinks and whether they brushed their teeth regularly. In addition, untreated caries in primary, permanent and all teeth were assessed according to World Health Organization criteria at the dentine level. Multilevel negative binomial regression models were used to assess the relation between dependent variables (untreated caries in primary, permanent and all teeth) and living environment (during and after the war and living in IDP camps) and parental educational attainment adjusted for oral health behaviours and demographic factors. The modifying effect of parental educational attainment (no, one and both parents university educated) on the association between living environment and the number of decayed teeth was also assessed. Data were available from 2406 Libyan children, 8-12 years old (mean = 10.8, SD = 1.8). The mean (SD) number of untreated decayed primary teeth was 1.20 (2.34), permanent teeth = 0.68 (1.32) and all teeth = 1.88 (2.50). Compared to children living in Benghazi during the war, children living in the city after the war had significantly greater number of decayed primary (adjusted prevalence ratio [APR] = 4.25, p = .01) and permanent teeth (APR = 3.77, p = .03) and children in IDP camps had significantly greater number of primary teeth (APR = 16.23, p = .03). Compared to children whose both parents were university-educated, those with no university-educated parents had a significantly greater number of decayed primary teeth (APR = 1.65, p = .02) and significantly less number of decayed permanent (APR = 0.40, p < .001) and all teeth (APR = 0.47, p < .001). There was a significant interaction between parental education and living environment in the number of all decayed teeth in children who lived in Benghazi during the war: children whose both parents were non-university-educated had significantly less number of all decayed teeth (p = .03) with no interaction effect in those living in Benghazi after the war or in IDP camps (p > .05). Children living in Benghazi after the war had more untreated decay in primary and permanent teeth than children during the war. Having parents with no university education was associated with greater or less untreated decay depending on the dentition. These variations were most pronounced among children during the war in all teeth with no significant differences in after-war and IDP camps groups. Further research is required to understand how living in war environment influenced oral health. In addition, children affected by wars and children living in IDP camps should be identified as target groups for oral health promotion programs.

Oral health characteristics in children and adolescents with Down syndrome.

To compare oral health indicators of children/adolescents with Down syndrome (DS) with a group of children/adolescents without DS. This cross-sectional study included 144 individuals with DS, ages 4 to 18 years, matched for age and sex with a group of 144 individuals without DS, and their parents/caregivers. Parents/caregivers completed a questionnaire regarding sociodemographic information and habits related to their children's oral health. Clinical examination of the children/adolescents evaluated dental caries experience (DMFT/dmft), bleeding on periodontal probing, presence of visible plaque, clinical consequences of untreated dental caries (PUFA/pufa), and malocclusion (DAI). The chi-square test, linear by linear test, and Mann-Whitney test were used to compare the variables between the groups (p < .05). Children/adolescents without DS brushed their teeth more times per day (p < .001) and had a higher frequency of daily sugar intake (p < .001). The children/adolescents in the DS group had a greater presence of gingival bleeding (p < .001) and had a greater number of cases of "severe malocclusion" and "very severe malocclusion" (p = .001). No difference was found in the prevalence of dental caries between the two groups. The children/adolescents in the DS group had a greater presence of gingival bleeding during the clinical examination and had a greater need for orthodontic treatment.

Potential Mesenchymal and Dental Pulp Stem Cell Usage for Regeneration of Dentine and its Complications

Tooth decay is an extremely common problem throughout the nation. As individuals pass the age of 20 years old, 90% have had some form of tooth decay. Along with this, more than 1 in 4 people have untreated tooth decay in the United States. When tooth decay is left untreated, an infection or trauma can often result in needing a root canal, and many other health problems. An average of 25 million root canals are performed every year, with around 40,000 being performed each day. Root canal treatment can result in pain or infection, as well as a weakened tooth that will be lost later in life. Due to the tooth pulp not being able to regenerate, there are many research studies being carried out to find a permanent and effective treatment. Mesenchymal and dental pulp stem cells are a large interest at this time due to their wide range of abilities to regenerate dentine and pulp in a tooth with necrotic tissue. While stem cells found in oral tissue are currently being studied in-vivo as well as in-vitro, the main focus is on producing the necessary types of stem cells for full dental tissue regeneration leading to complete re-gain of function. This review outlines the findings from recent years with stem cell usage in regeneration within the oral cavity.

Tooth-level predictors of tooth loss and exposed bone after radiation therapy for head and neck cancer

BackgroundThe objective of this study was to identify tooth-level risk factors for use during preradiation dental care management to predict risk of tooth failure (tooth lost or declared hopeless) and exposed bone after radiation therapy (RT) for head and neck cancer (HNC). MethodsThe authors conducted a prospective observational multicenter cohort study of 572 patients receiving RT for HNC. Participants were examined by calibrated examiners before RT and then every 6 months until 2 years after RT. Analyses considered time to tooth failure and chance of exposed bone at a tooth location. ResultsThe following pre-RT characteristics predicted tooth failure within 2 years after RT: hopeless teeth not extracted pre-RT (hazard ratio [HR], 17.1; P < .0001), untreated caries (HR, 5.0; P < .0001), periodontal pocket 6 mm or greater (HR, 3.4; P = .001) or equaling 5 mm (HR, 2.2; P = .006), recession over 2 mm (HR, 2.8; P = .002), furcation score of 2 (HR, 3.3; P = .003), and any mobility (HR, 2.2; P = .008). The following pre-RT characteristics predicted occurrence of exposed bone at a tooth location: hopeless teeth not extracted before RT (risk ratio [RR], 18.7; P = .0002) and pocket depth 6 mm or greater (RR, 5.4; P = .003) or equaling 5 mm (RR, 4.7; P = .016). Participants with exposed bone at the site of a pre-RT dental extraction averaged 19.6 days between extraction and start of RT compared with 26.2 days for participants without exposed bone (P = .21). ConclusionsIndividual teeth with the risk factors identified in this study should be considered for extraction before RT for HNC, with adequate healing time before start of RT. Practical ImplicationsThe findings of this trial will facilitate evidence-based dental management of the care of patients receiving RT for HNC. This clinical trial was registered at Clinicaltrials.gov. The registration number is NCT02057510.

Differential Unmet Needs and Experience of Restorative Dental Care in Trajectories of Dental Caries Experience: A Birth Cohort Study

Dental caries is a chronic and cumulative disease but little has been reported on the continuity of the disease and its treatment through life. Group-based multi-trajectory modeling was used to identify developmental trajectories of untreated carious tooth surfaces (DS), restored tooth surfaces (FS), and teeth extracted due to caries (MT) from ages 9 to 45 years in a New Zealand longitudinal birth cohort, the Dunedin Multidisciplinary Health and Development Study (n = 975). Associations between early-life risk factors and trajectory group membership were examined by specifying the probability of group membership according to a multinomial logit model. Six trajectory groups were identified and labeled: “low caries rate”; “moderate caries rate, maintained”; “moderate caries rate, unmaintained”; “high caries rate, restored”; “high caries rate, tooth loss”; and “high caries rate, untreated caries”. The two moderate-caries-rate groups differed in count of FS. The three high-caries-rate groups differed in the relative proportion of accumulated DS, FS, and MT. Early childhood risk factors associated with less favorable trajectories included higher dmfs scores at age 5, lack of exposure to community water fluoridation during the first 5 years of life, lower childhood IQ, and low childhood socioeconomic status. Parent self-ratings of their own or their child’s oral health as “poor” were associated with less favorable caries experience trajectories. Children who had clinical signs of dental caries together with a parent rating of child’s oral health as poor were more likely to follow a less favorable caries trajectory. Higher deciduous dentition caries experience at age 5 years was associated with less favorable caries trajectories, as were children whose parents gave “poor” ratings of their own or their child’s oral health. These findings highlight the considerable intergenerational continuity in dental caries experience from early childhood to midlife. Subjective measures of child oral health are informative and might aid as predictors of adult caries experience in cases where childhood dental clinical data were not available.

Comparative Evaluation of Extrusion of Apical Debris in Primary Maxillary Anterior Teeth Using Two Different Rotary Systems and Hand Files: An In Vitro Study.

Successful outcome of pulp therapy depends on good chemomechanical preparation of the canals. This is completed with the help of various upcoming rotary and hand files. However, during this preparation, there might be an apical extrusion of the debris which may result in postoperative complications. The aim of this study was to evaluate and compare the number of debris apically extruded during canal preparation using two different pediatric rotary file systems and conventional hand file systems in primary teeth. 60 primary maxillary central incisors that were extracted due to trauma or untreated dental caries with no signs of resorption were taken. Canal preparation was executed using three different file systems: Group A: Group A hand K file system, Group B Kedo S Plus, Group C Kedo SG Blue. For each of these files using the Myers and Montgomery model, the pre- and post-weight of the eppendorf tube was assessed to quantify the number of apical debris. The maximum extrusion of apical debris was noticed with the Hand K-file system. The least debris was noticed in the Kedo S Plus file system. Statistical analysis revealed that there were highly significant differences in apical extrusion and debris when comparing hand files and rotary files and also between the two rotary files used. Apical debris collection is an unavoidable outcome of canal instrumentation. Among the file systems compared, rotary files had lesser extrusion when compared to hand files. Among the rotary files, Kedo S plus showed normal extrusion compared to SG Blue.
