The impact of malnutrition on dental health of 12-year-old children: a study on permanent teeth caries, cariogenic bacteria and salivary IgA.

Malnutrition in children is epidemic in developing countries. Several health issues and consequences are believed to develop due to this phenomenon. Children's oral health is also affected by malnutrition. The main aspects of oral health status are caries experience, the existence of cariogenic bacteria, and salivary immunoglobulin A.

The accuracy of parent/carer proxy-reporting of caries experience in children and association with socioeconomic circumstances: a cross-sectional data linkage study.

To compare parent/carer proxy-reported dental caries experience of their 5-year-old child with epidemiological survey clinician examination of caries experience in the same children. To determine any differences in the accuracy by area-based socioeconomic group. A cross-sectional data linkage study linked data from the Growing Up in Scotland (GUS) study and the National Dental Inspection Programme (NDIP) school epidemiology survey. Parent/carer proxy-reported caries experience was compared with clinician-measured caries experience on n=3008 children, and data were stratified by home-residential area-based socioeconomic deprivation levels (Scottish Index of Multiple Deprivation (SIMD)). Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated overall and stratified by SIMD. Overall, parent/carer proxy-reporting had low sensitivity (42.3% 95%CI: 39.0, 45.7) that decreased with decreasing deprivation (SIMD-1(most deprived): 49.4% to SIMD-5 (least deprived): 37.2%). Specificity remained consistently high overall and across area-based socioeconomic deprivation levels (overall=96.2%, 95%CI: 95.3, 97.0; SIMD-1: 94.4% SIMD-5: 97.8%). In children whose parents/carers reported them to have caries experience (GUS) a high percentage were found to have caries experience (NDIP) (PPV=81.8%, 95%CI: 78.2, 84.9). Parent/carer proxy-reporting of caries experience in 5-year-old children had very low sensitivity and was lowest in children from the least deprived areas. In contrast, parents/carers who reported their child had caries experience did so reasonably accurately. This study concludes that proxy reporting caries experience is not sufficiently sensitive to replace clinician examination in assessing dental caries experience in surveys of child populations and highlights the importance of data linkage to routine datasets.

The level of dental fear and anxiety is higher in children with both severe Molar-Incisor Hypomineralisation and active dental caries lesions compared to children without these conditions

PurposeTo assess levels of dental fear and anxiety (DFA) in children with and without Molar-Incisor Hypomineralisation (MIH) and dental caries lesions.MethodsIn this cross-sectional observational study, 159 children between 8 and 12 years of age were included. For the evaluation of DFA, children responded to the validated version of the Children’s Fear Survey Schedule-Dental Subscale. MIH was assessed using the MIH Index. To evaluate the activity of dental caries lesions and dental caries experience, the Nyvad criterion and the dmft/DMFT index were used, respectively. Dental hypersensitivity was evaluated using air stimulation and a Visual Analogue Scale. The association between MIH and dental caries with DFA was assessed using the generalised linear model with Poisson family, identity link function and robust variance estimation. The significance level was set at 5%.ResultsThe mean DFA score was 28.3 (SD = 13.4) with scores ranging from 15 to 64. Amongst children presenting both MIH and dental caries, the perception of DFA was notably higher compared to those with either MIH or dental caries alone. The activity of caries lesion in patients with MIH also influenced DFA levels (diff: 18.6; 95% CI: 12.0–25.2; p < 0.001). Dental caries experience in the primary dentition also demonstrated statistical significance concerning DFA (95% CI: 0.8–13.3; p value = 0.027).ConclusionChildren with MIH exhibit higher levels of DFA than children without MIH. The experience of dental caries and the activity of caries lesions significantly influence the perception of DFA in children with MIH.

Do Parental and Children’s Dental Anxiety Affect Childhood Dental Caries?

Background: Dental anxiety is an unpleasant reaction to fear or stress related to the dental environment and can be observed in both parents and children as dental patients. Despite several studies challenging the significance of parental anxiety in influencing a child's response to dental treatment, conflicting results have emerged regarding the impact of both parental and children's anxiety on the development of dental caries. Objectives: This study aimed to explore the association between parental and children's dental anxiety and the occurrence of dental caries in children. Methods: A cross-sectional study involving 7 - 12-year-old students and their parents in schools of Rasht, Iran, utilized the Modified Dental Anxiety Scale (MDAS) for parents and the Modified Child Dental Anxiety Scale (MCDAS) questionnaire for children. Participants were chosen through a multistage sampling process. A trained dentist assessed children's dental caries using the DMFT/dmft (decayed, missing, and filled teeth) Index. The data were analyzed using the chi-square test and linear regression. Results: The study included 275 parents and an equal number of children, with a mean child age of 9.32 ± 1.85 years. The findings indicated a significant relationship between maternal dental anxiety and DMFT + dmft scores in boys (P = 0.049). The study revealed that the number of teeth with caries experience (P = 0.023), child's sex (P = 0.007), history of dental clinic visits (P = 0.045), and maternal dental anxiety (P = 0.043) significantly influenced the child's dental anxiety. Conclusions: Children with anxious parents showed lower DMFT/dmft values, suggesting increased attention to their dental health. The study highlights the impact of parental dental anxiety on children's oral well-being and emphasizes the need for comprehensive strategies to address dental anxiety in both parents and children.

Selected Saliva-Derived Cytokines and Growth Factors Are Elevated in Pediatric Dentofacial Inflammation.

Dentofacial inflammation resulting from untreated dental caries is a serious disease that can spread to deeper tissues of the neck and face. This study aimed to analyze salivary cytokine profiles as potential biomarkers of acute odontogenic infections in children. The study group consisted of 28 children aged 3-17 years old with acute dentofacial infections (DI) and a control group (caries experience, CE) of 52 children aged 4-17 years old with uncomplicated dental caries. The cytokine profile was analyzed using the Bio-Plex Pro Human Cytokine 27-Plex kit in the saliva of children in both groups. The levels of IL-4, IL-15, FGF-2, G-CSF, and PDGF-BB were significantly increased in children with dentofacial infections compared to the control group. In contrast, the levels of other cytokines, such as IL-2, IL-7, IL-9, IL-13, GM-CSF, and IFN-γ, did not show statistically significant differences between these two groups. IL-4, IL-15, FGF-2, G-CSF, and PDGF-BB may serve as potential selective biomarkers of inflammation of the oral cavity in children. These biomarkers can be useful in identifying and monitoring the progress and treatment of bacterial infections resulting in dentofacial inflammation.

Oral Health-Related Quality of Life of Hong Kong Kindergarten Children Receiving Silver Diamine Fluoride Therapy.

The objective of this prospective 12-month observational study is to examine the oral health-related quality of life (OHRQoL) among Hong Kong young children aged 3-4 years old receiving silver diamine fluoride (SDF) therapy for carious upper anterior primary teeth. A parental questionnaire was used to collect each child's sociodemographic background and oral health habits at baseline. Data on parents' satisfaction with their child's dental aesthetics were collected at baseline and during a 12-month visit. The Chinese Early Childhood Oral Health Impact Scale (C-ECOHIS) was used to measure OHRQoL. A trained dentist performed examinations and recorded caries experience (dmft) and oral hygiene (visible plaque index) at baseline and 12 months. SDF was applied to the carious lesions. Out of 286 invited children, 248 (87%, 248/286) participated, and 211 (85%, 211/248) attended the 12-month examination. All SDF-treated carious lesions were discoloured at the 12-month examination. Regression analysis showed that the baseline C-ECOHIS score was associated with dmft (p < 0.001). The baseline and 12-month C-ECOHIS scores were 4.6 ± 5.5 and 5.0 ± 5.6, respectively (p = 0.42). The scores for parental satisfaction with dental aesthetics at baseline and 12 months were 59% to 46% (p < 0.001). Satisfaction was negatively associated with the number of discoloured upper anterior teeth (p < 0.001). In conclusion, SDF discoloured the carious upper anterior teeth of the Hong Kong kindergarten children. However, the discoloured lesions had no significant effects on the OHRQoL of these children. However, more parents became dissatisfied with their child's dental aesthetics after SDF therapy. Hence, clinicians should inform parents well before they perform SDF therapy on children.

Impact of dental caries and Self-perceived oral health on daily lives of children and mothers in rural Egypt: a household survey

BackgroundThe present study assessed the impact of oral health on the daily lives of children and mothers living in a rural area in Northwestern Egypt.MethodsA cross-sectional household survey including children between 6 and 12 years old and their mothers was conducted in rural Egypt, 2019–2020. Data were collected using clinical examination and interview-based questionnaires of children and mothers. Three binary logistic regression models were used to assess the relationship between the dependent variables (oral health impact (yes, no) on avoiding smiling, chewing problems, and missing school (children) and avoiding social events (mothers)), and the explanatory variables: oral health (clinically-assessed caries experience and self-reported oral health) controlling for sociodemographic profile (child age and sex, mother’s education), daily toothbrushing and village of residence.ResultsA total of 211 households with 355 children and 211 mothers were included (91.5% response rate). About 54% of the children were girls, mean (SD) age = 8.7 (2.05) years and 82.3% did not brush their teeth daily. Mother’s mean (SD) age was 31.70 (5.45) years. Because of dental problems, 31.3% of children reported chewing difficulties, 31% avoided smiling compared to 76.3% and 43.6% of mothers. Also, 30.4% of children missed school and 76.8% of mothers reported reduced participation in social activities. In children, the number of decayed anterior teeth was associated with significantly higher odds of avoiding smiling (AOR = 1.22, 95%CI: 1.03, 1.44). In mothers, a greater number of posterior missing teeth was associated with significantly higher odds of chewing difficulties (AOR = 1.21, 95%CI: 1.01, 1.45), and a greater number of all missing teeth was associated with significantly higher odds of reduced participation in social events (AOR = 1.30, 95%CI: 1.30, 1.57). Good/ very good reported oral health in children and mothers was associated with lower odds of avoiding smiling and chewing problems (p < 0.05).ConclusionDecayed anterior teeth in children have a negative impact on smiling whereas missing teeth in mothers affect the ability to chew food and socialize. The psychological, functional, and social impacts of caries in this rural setting needs to be mitigated by improving oral health literacy and access to care.

Assessment of parents’ oral health related behaviours and its relationship with oral health status of the children aged between 6-12 years in Davangere city: a cross-sectional survey

Background: It is widely acknowledged that the behaviour of parents affects their children's health. This study aimed to evaluate the relationship between oral health behaviour of parents and oral health status of their children aged between 6-12 years. Methods: A cross-sectional survey was conducted among 420 parent-child dyads with children aged between 6-12 years. A self-designed proforma was used for recording the sociodemographic details, with a questionnaire to assess parents’ oral health-related behaviours followed by clinical examination of the children for their oral health status. The Chi-square test, spearman’s correlation test and binary logistic regression analysis were applied by considering Statistical significance at p&lt;0.05. Results: The majority of the parents reported of having good oral health-related behaviours (60.2%). When children’s oral health status was assessed, more than half of the children had low caries experience (62.5%), showed a milder form of gingivitis (96.2%) and good oral hygiene status (57.4%). No statistically significant association was found between parents’ oral health-related behaviours with the children’s oral health status. Conclusions: Parents’ oral health-related behaviours did not influence the children’s oral health status.

Oral Health Status of the Institutionalized Elderly in Mangalore City, Karnataka, South India: Extents, Insights and Action

Oral diseases are progressive and cumulative across the life span and due to this reason, the oral health of the institutionalized elderly is of concern within the realm of geriatric care. An improvement in oral health among the institutionalized elderly will boost their social life, self-confidence, mastication and nutritional status, thereby bringing a positive outlook. To assess the periodontal status, dental caries experience, prosthetic status, and prosthetic need of institutionalized elderly in Mangalore. A cross-sectional study was conducted to assess the dental caries experience, periodontal status, prosthetic status, and prosthetic needs of 143 elderly individuals living in geriatric homes in Mangalore city. The demographic data, periodontal status, prosthetic status, and prosthetic need was obtained using the WHO Oral Health Assessment Form 1997. Dental caries experience was recorded according to the WHO modified DMFT Index. Descriptive statistics was obtained using SPSS version 16. The mean dental caries experience of the study subjects was 8.80. The presence of supra or sub gingival calculus was noted in 44.8 % of the subjects and the presence of a pathological pocket of 4 mm or more was seen in 32 %. About 33 of the subjects did not require any kind of prosthesis in the upper &amp; lower arch. From this survey of the institutionalized elderly population, it was evident that, half of them had supra or subgingival calculus deposits and more than 76.9 % have one or the other need for a prosthesis.

Oral health inequalities in immigrant populations worldwide: a scoping review of dental caries and periodontal disease prevalence

BackgroundInequalities in immigrants' oral health are often masked in population-level data. Therefore, this paper was planned to assess the prevalence data on oral health diseases, namely dental caries, and periodontitis, among immigrants worldwide.MethodsFollowing a systematic search in Scopus, Embase, and PubMed for studies published between 2011 and 2023, 1342 records were identified. Following title and abstract screening, 76 studies remained for full-text eligibility-screening based on predefined inclusion criteria. Thirty-two studies were included in the review.ResultsDental caries figures were higher in immigrant populations compared to the local population, regardless of host countries, age, gender, or nationality. In children, the overall mean and standard deviation (SD) for decayed, missing, and filled teeth in the primary dentition (d3mft) was 3.63(2.47), and for D3MFT (permanent dentition), it was 1.7(1.2).Upon comparing overall mean caries counts in children and adults with their control groups in the included studies, untreated dental caries (D3T and d3t) constituted the dominant share of caries experience (D3MFT and d3mft) in immigrant children. For the local population, the highest proportion of caries experience was attributed to filled teeth (FT and ft).Dentin caries prevalence among immigrants ranged from 22% to 88.7% in the primary dentition and 5.6% to 90.9% in the permanent dentition. Gingivitis ranged from 5.1% to 100%. Oral health varied greatly between studies. Regarding oral health accessibility, 52% to 88% of immigrant children had never been to a dentist, suggesting a very limited level of accessibility to dental health services.ConclusionIt is imperative to develop interventions and policies that have been customized to address the oral health disparities experienced by immigrant populations. Additionally, host countries should actively implement measures aimed at enhancing the accessibility of oral health care services for these individuals. The utilization of available data is crucial in establishing a hierarchy of objectives aimed at enhancing the oral health of immigrant populations.Trial registrationThe Scoping review protocol was registered at OSF Registries with registration number (https://doi.org/10.17605/OSF.IO/MYXS4).

Evaluating the Effectiveness of the Nudge Theory in Improving the Oral Self-Care of Schoolchildren with Refugee and Immigrant Backgrounds in Mashhad, Iran.

Nudge theory proposes using subtle interventions to encourage individuals to make better decisions. The aim of this study was to evaluate the effectiveness of the Nudge theory in plaque control and assess caries experience among third-grade primary schoolchildren with refugee and immigrant backgrounds in Mashhad, Iran. Moreover, Afghan and Iranian schoolchildren were compared to assess differences in oral health outcomes. A quasi-experimental field trial was conducted in three public primary schools, comprising 309 participants approximately 9 years old. Interventions were randomly assigned to three schools: School I Messages based on Social Norms (MSN), School II Messages based on Fear of Negative Outcome (MFNO), and School III control group (C). MSN and MFNO received customized motivational video clips at baseline, while C only received Oral hygiene instruction (OHI). All participants received OHI, a brush, and toothpaste. Baseline plaque index (PI) and caries experience in primary and permanent dentition (dmft/DMFT) were recorded. PI was reassessed at two weeks, two months, and six months post-intervention. All data were subjected to statistical analysis. The mean PI decreased significantly in all three groups at the two-week follow-up (p < 0.01). The PI improvements declined over a six-month follow-up period in all groups, and the mean PI difference after six months compared to the pre-intervention was significant only in MSN and MFNO (p < 0.01), while C reverted almost to the pre-study level. Schoolchildren with at least one filled tooth or Iranian nationality showed a greater PI reduction (p < 0.01, p = 0.05). The overall mean ± SD dmft and DMFT were 4.24 ± 2.11 and 1.70 ± 1.24, respectively. Among all the examined participants, 32 (10.40%) individuals were caries-free. The mean dmft was statistically significantly higher in Afghan children than in Iranians (p = 0.01). MSN was more effective on PI reduction in the short term, while MFNO was more long-lasting. Using the Nudge theory via visual aids was more effective in motivating children to perform better oral self-care than solely traditional OHI.

Salivary Proteins and Metabolites as Caries Biomarkers in Adolescents.

The identification of salivary molecules that can be associated to dental caries could provide insights about caries risk and offer valuable information to develop caries prediction models. However, the search for a universal caries biomarker has proven elusive due to the multifactorial nature of this oral disease. We have therefore performed a systematic effort to identify caries-associated metabolites and proteins in saliva samples from adolescents that had a caries experience and those that were caries-free. Quantification of approximately 100 molecules was performed by the use of a wide range of techniques, ranging from nuclear magnetic resonance metabolomics to ELISA, Luminex or colorimetric assays, as well as clinical features like plaque accumulation and gingival index. In addition, simplified dietary and oral hygiene habits questionnaires were also obtained. The caries-free group had significantly lower consumption of sweetened beverages and higher tooth brushing frequency. Surprisingly, very few compounds were found to individually provide discriminatory power between caries-experienced and caries-free individuals. The data analysis revealed several potential reasons that could underly this lack of association value with caries, including differences in metabolite concentrations throughout the day, a lack of correlation between metabolite concentrations in plaque and saliva, or sex-related differences, among others. However, when multiple compounds were combined by multivariate analysis and random forest modeling, a combination of 3-5 compounds were found to provide good prediction models for morning (with an AUC accuracy of 0.87) and especially afternoon samples (AUC = 0.93). While few salivary biomarkers could differentiate between caries-free and caries-experienced adolescents, a combination of markers proved effective, particularly in afternoon samples. To predict caries risk, these biomarkers should be validated in larger cohorts and longitudinal settings, considering factors such as gender differences, and variations in oral hygiene and diet.

What can impact on the presence of carious lesions in first permanent molars? Revisiting the association between MIH and caries.

Assess whether the independent variables (IV) such as number of MIH-affected molars, MIH severity, past caries experience, visible plaque index (VPI), gingival bleeding index (GBI), age, and gender affect the presence of caries lesion (DMF_s) in first permanent molars, considering or not atypical restoration in MIH-affected molars as a previous caries lesion. A sample of 476 schoolchildren, aged 6-10years, were evaluated for MIH and caries diagnosis, using the Severity Scoring System (MIH-SSS) and the International Caries Detection and Assessment System (ICDAS), respectively. From the ICDAS, the DF-s/ D-s and df-s were calculated. The Zero-inflated Negative Binomial Regression was used to evaluate the impact of the IV on the dependent variable, considering or not the restorative component in MIH-affected molars. When the presence of caries was evaluated with the restorative component, age, MIH severity and past caries experience had a significant impact on the dependent variable (R2 = 0.176). Without the restorative component in MIH-affected molars, only age and past caries experience were statistically significant (R2 = 0.167). Since in the case of MIH teeth restoration may be attributed to post-eruptive breakdown rather than previous caries lesions, in the present study MIH did not influence the presence of caries lesions in the MIH-affected molars showing that restoration is not an adequate parameter for measuring the historical occurrence of caries. The first permanent molars may not necessarily be at an increased risk of caries due to MIH if the etiological factors for caries development are effectively managed.

Craniosynostosis: orofacial and oral health perspectives with masticatory insights

BackgroundCraniosynostosis (CS), premature fusion of one or more cranial sutures, leads to abnormal skull development, impacting both facial esthetics and oral function. This study aimed to evaluate the specific orofacial and oral health characteristics, including masticatory performance, in Thai patients with CS.MethodsA comparative study was conducted with Thai CS patients aged 6–17 years and a control group of healthy individuals with similar age distribution. Assessments included craniofacial morphology, oral health status, and masticatory performance. Intergroup comparisons utilized appropriate statistical tests.ResultsThe study included 24 CS patients with a mean age of 10.11 ± 2.98 years and 30 controls. CS patients exhibited a significantly higher prevalence of various oral conditions compared to controls: cleft palate (20.8%), anterior open bite (41.7%), anterior crossbite (54.2%), posterior crossbite (50%), combined anterior–posterior crossbite (45.8%), dental crowding in both maxilla and mandible (50% and 45.8% respectively), congenitally missing teeth (50%), supernumerary teeth (12.5%), and eruption failure (54.2%). Furthermore, CS patients exhibited significantly higher caries prevalence and susceptibility, alongside poorer oral hygiene, compared to controls. Regarding jaw relationships, CS patients exhibited a significantly higher proportion of Angle's Class III malocclusion (50%) compared to the control group, where Class I malocclusion was predominant (50%). Masticatory performance, assessed using the two-color gum mixing ability test, showed significantly higher hue variance in CS patients (0.12 ± 0.07) compared to the control group, indicating reduced chewing performance.ConclusionThis study underscores the significant orofacial and oral health challenges faced by children with CS, including a high prevalence of malocclusions, dental anomalies, elevated caries experience, and compromised masticatory function. These findings emphasize the importance of tailored interventions and comprehensive oral healthcare strategies to address the unique needs of this population and improve their overall quality of life.

Characteristics Of Occlusion In Primary Dentition And Its Relationship With Caries In Preschool Children In Aydın

Objective: The purpose of this study was to determine the clinical characteristics of occlusion in primary dentition and examine its relationship to caries experience in preschoolers in Aydın, TÜRKİYE. Materials and methods: The study was conducted among 962 children aged 3–5 years from preschoolers in a cross-sectional design. The clinical features were evaluated according to Björk et al and the caries examination was carried out with dft index. Results: The most common type of terminal plane relationship was flush type (46.7%) and primary canine relationship was Class I (69.6%). The most common type of irregularity was the prevalence of deep overbite (55.7%) followed by midline deviation (15.8%). Approximately half of the children (51.2%) had at least one carious tooth but caries experience was not related with any of the occlusal irregularities. Conclusion: Occlusal characteristics of the preschool children were defined and no relationship was found between these features and gender or caries experience.

Burden of oral diseases predicts development of excess weight in early adolescence: a 2-year longitudinal study

Dental caries, gingivitis, and excess weight are highly prevalent, interconnected chronic conditions. The association of oral health with the development of adiposity among children is sparsely addressed. We examined the association of oral health to the development of excess weight and central obesity in early adolescence during a 2-year follow-up period. This prospective study was conducted with 2702 children aged 9–12 years at baseline from the Finnish Health in Teens study. Their weight development was followed up for 2 years. Body mass index with age- and sex-specific cut-offs and the waist–height ratio indicated weight status and central obesity. Oral health data (caries experience and gingivitis/calculus) were collected from outpatient records of public dental services. Having both caries experience and gingivitis/calculus was considered burden of oral diseases. Of the sample, 74% were caries-free but 70% exhibited gingivitis and/or calculus, and 20% had both caries experience and gingivitis/calculus. During the follow-up period, 5.3% (n = 124) and 4.7% (n = 118) of the children became overweight/obese or centrally obese, respectively. Having both caries experience and gingivitis/calculus associated with the development of excess weight in a fully adjusted model (HR 1.75, 95% CI 1.03–2.97) but not of central obesity. Caries experience or gingivitis/calculus alone did not associate with adiposity development.Conclusion: Having burden of oral diseases without excess weight at early adolescence could imply future weight gain; thus, normal-weight individuals with both caries experience and gingivitis/calculus could be targeted with preventive measures. Our findings warrant further research to explore whether oral diseases and the development of obesity merely share risk factors or if their relationship is of causal nature.What is Known:• Association of excess weight with caries experience and gingivitis is known to exist both cross-sectionally and longitudinally in children and adolescents.What is New:• Burden of oral diseases, that is, having both caries experience and gingivitis/calculus, was associated with becoming overweight or obese 2 years later during early adolescence.• Normal-weight individuals with burden of oral diseases at early adolescence could be targeted with preventive measures against excess weight gain.

Oral processing behavior and dental caries; an insight into a new relationship.

Previous evidence suggests an individual variation in the preferred oral processing behavior. Individuals can be classified as firm processing(FPL) or soft processing likers(SPL). FPL(crunchers and chewers) prefer using their teeth while SPL(smooshers and suckers) prefer using the tongue and the palate when processing different food items. Variation in the preferred oral processing behavior has been associated with differences in food texture preference and eating time. Time is one of the factors directly related to the development of dental caries(tooth decay). Oral retention and eating times are associated with greater caries experience. This study aims to explore if a relationship exists between the preferred oral processing behavior and the individual's caries experience. This was a cross-sectional, dental center-based study conducted at Jordan University of Science and Technology. Five hundred participants consented to fill out the preferred oral processing behavior(POPB) questionnaire. Anthropometric measurements (including weight, height, and waist circumference) were recorded. A single trained and calibrated dentist registered each participant's caries experience and plaque levels using the DMFS index and plaque index of Silness and Loe. A total of 351(70.2%) and 149(29.8%) participants were typed as FPL and SPL, respectively. SPL demonstrated higher levels of dental caries experience compared to FPL. The mean DMFS score for SPL was 28.8(±25.43) while for FPL was 18.71(± 18.34). This difference remained significant after adjustment for confounders(P<0.001). SPL exhibited a significantly higher mean score for the "M" component(P <0.001) while no significant difference in the mean score of the "D"(P = 0.076) and "F"(P = 0.272) components was observed when compared to FPL. The current findings provide new insight into a possible relationship between the preferred oral processing behavior and an individual's caries experience. A relationship in which the preferred oral processing behavior can potentially affect and/or be affected by the dental caries experience.

The relationship between the source of oral health information and dental caries: Findings from Child Dental Health Survey 2013 in England.

To determine the magnitude and shape of the relationship between dental caries experience and the source of oral health information in England. This was a cross-sectional study using the Child Dental Health Survey 2013 in England. Using a negative binomial model, the relationship between the number of decayed, missing, filled teeth (DMFT) of 12- and 15-year-old students and their primary source of oral health information was assessed. The sources of oral health information included parents, television, newspapers, the Internet, and social media. The adjusted model included age, sex, and the Index of Multiple Deprivation (IMD). R was used for data handling, analysis and reporting. Overall, 2,372 children were assessed (48.7% female, 48.6% 12-year-old). For the majority, the primary source of oral health information was their parents (89.5%) followed by the Internet (43.4%). Over nine-tenth of the participants had a DMFT = 0. The adjusted model showed that the prevalence rate of DMFT for the children whose primary source of information is their parents (0.45) or television (0.62) is lower than 1. The prevalence rate for the Internet (1.17) and social media (1.67) was higher than 1, but they were removed from the final model due to being non-statistically significant. Age and deprivation had a direct relationship with the prevalence rate of DMFT, meaning that 15-year-olds and children from more deprived areas had a higher prevalence rate of DMFT. Children whose primary source of oral health information was their parents or television had a lower DMFT. On the contrary, using the Internet or social media as the source of oral health information was associated with higher caries experience among schoolchildren.

Prevalence and Distribution of Dental Caries among Iraqi People

Abstract Background: Dental caries is the most prevalent oral disease worldwide. It is still a public health problem, particularly in developing countries. Objectives: The aim of this study was to measure the occurrence of dental caries among patients attending dental school and to investigate the type of dental caries by age, sex, and geographic area. Materials and Methods: After obtaining an appropriate ethical approval, the occurrence and type of dental caries according to G.V. Black classification were recorded among all patients aged 16 years and over during routine dental treatment at the dental hospital, College of Dentistry, University of Babylon, Hillah city, Babil governorate. World Health Organization’ criteria were used to diagnose and detect dental caries. Results: The final sample size was 463 individuals distributed as 217 (46.87%) men and 246 (53.13%) women. Overall, 1851 carious lesions were noticed, in which class I (68%) represents the most prevalent type of dental caries in the study sample followed by class II (20%), then class III (6%), and the least prevalent types (3%) were class IV and class V. There was no significant difference regarding the effect of gender on different caries classes (P &gt; 0.05). However, a significant difference was recorded regarding the effect of area of residence on different caries classes (P &lt; 0.05). Conclusions: In this study, high percentage of class I lesions in comparison to other classes of Black’s classification was noticed among the examined patients. Women experienced more dental caries than men and the area of residency had a significant impact on caries experience.

Salivary Biophysical Properties in Relation to Dental Caries Severity Among Type 1 Diabetic Children

Diabetes Mellitus is a multifactorial metabolic disorder characterized by elevated blood glucose levels or hyperglycemia. Diabetes Mellitus may cause many oral problems as a result of both micro- and macrovascular complications. We aimed to assess the probable relationship between the severity of dental caries and the biophysical properties of saliva (flow rate, PH, and viscosity). Materials and Methods: A cross-sectional comparative study was conducted in Karbala City, in which a sample of 45 children with type 1 diabetes aged between 10-12 years was compared with a group of 45 non-diabetic children matched in age and gender. Dental caries severity and experience were recorded and diagnosed using Manji et al.'s criteria and the decayed, missing, and filling index (DMFS/dmfs). Unstimulated salivary specimens were collected to evaluate flow rate, pH, and viscosity. Pearson (r) correlation coefficient test and one-way ANOVA test were employed for data analysis using SPSS-22. Results: Salivary levels of viscosity and flow rate were not statistically significant (P &gt; 0.05) predicators regarding the dental caries experience and severity among type1 diabetic children (controlled and uncontrolled) while pH level of saliva was a statistically significant predictor regarding dental caries experience (DS/ DMFT) among uncontrolled diabetic children. Conclusion: Compared to non-diabetic children, type 1 diabetic children exhibited pronounced changes in salivary biophysical properties but unpronounced changes in caries status.
