Sugary carbohydrate foods have long been associated with increased risk of dental caries formation, but the dental health impact of starchy carbohydrates, particularly those with a high glycemic index (GI), has not been well examined. Aim: To investigate the effect of different starchy foods varying in their GI, on acute changes in dental plaque pH. Methods: In a series of sub-studies in healthy adults, common starchy carbohydrate foods, including white bread, instant mashed potatoes, canned chickpeas, pasta, breakfast cereals, white rice, and an oral glucose solution were consumed in fixed 25 g available carbohydrate portions. The change in dental plaque pH was assessed postprandially over 1 h and capillary plasma glucose was measured at regular intervals over 2 h. Results: Higher GI starchy foods produced greater acute plaque pH decreases and larger overall postprandial glucose responses compared to lower GI starchy foods (white bread compared with canned chickpeas: −1.5 vs. −0.7 pH units, p = 0.001, and 99 ± 8 mmol/L min vs. 47 ± 7 mmol/L min, p = 0.026). Controlling for other food factors (food form and nutritional composition), lower GI versions of matched food pairs produced smaller plaque pH excursions compared to higher GI versions of the same food. Using linear regression analysis, the GI value of starchy carbohydrate foods explained 60% of the variation in maximum plaque pH nadir and 64% of the variation in overall acute dental plaque pH excursion (p < 0.01). Conclusion: The findings imply that starchy foods, in particular those with a higher GI, may play a role in increasing the risk of dental caries.

A selected group of oral bacteria commonly associated with dental health is capable of producing alkali via the arginine deiminase system (ADS), which has a profound impact on the pH of human oral biofilms. An increased risk for dental caries has been associated with reduced ADS activity of the bacteria in oral biofilms. Arginolytic bacterial strains from dental plaque samples of caries-free and caries-active adults were isolated and characterized to investigate the basis for differences in plaque ADS activity between individuals. Fifty-six ADS-positive bacterial strains were identified by 16S rRNA gene sequencing, and their ADS activity levels were compared under standard growth conditions. The spectrum of bacterial ADS activity ranged from 45.2 to 688.0 units (mg protein)-1. Although Streptococcus sanguinis was the most prevalent species, other Streptococcus sp. were also represented. Biochemical assays carried out using 27 ADS-positive strains under conditions known to induce or repress ADS gene expression showed substantial variation in arginolytic activity in response to pH, oxygen and the availability of carbohydrate or arginine. This study reveals that the basis for the wide spectrum of arginolytic expression observed among clinical strains is, at least in part, attributable to differences in the regulation of the ADS within and between species. The results provide insights into the microbiological basis for intersubject differences in ADS activity in oral biofilms and enhance our understanding of dental caries as an ecologically driven disease in which arginine metabolism moderates plaque pH and promotes dental health.

Starchy Foods

Sucrose and starches are the predominant dietary carbohydrates in modern societies. While the causal relationship between sucrose and dental caries development is indisputable, the relationship between food starch and dental caries continues to be debated and is the topic of this review. The current view of dental caries etiology suggests that in-depth evaluation of the starch-caries relationship requires the consideration of several critical cariogenic determinants: (1) the intensity (i.e., the amount and frequency) of exposure of tooth surfaces to both sugars and starches, (2) the bioavailability of the starches, (3) the nature of the microbial flora of dental plaque, (4) the pH-lowering capacity of dental plaque, and (5) the flow rate of saliva. Studies of caries in animals, human plaque pH response, and enamel/dentin demineralization leave no doubt that processed food starches in modern human diets possess a significant cariogenic potential. However, the available studies with humans do not provide unequivocal data on their actual cariogenicity. In this regard, we found it helpful to distinguish between two types of situations. The first, exemplified by our forebears, people in developing countries, and special subject groups in more modern countries, is characterized by starch consumption in combination with a low sugar intake, an eating frequency which is essentially limited to two or three meals per day, and a low-to-negligible caries activity. The second, exemplified by people in the more modern societies, e.g., urban populations, is characterized by starch consumption in combination with significantly increased sugar consumption, an eating frequency of three or more times per day, and a significantly elevated caries activity. It is in the first situation that food starches do not appear to be particularly caries-inducive. However, their contribution to caries development in the second situation is uncertain and requires further clarification. Although food starches do not appear to be particularly caries inducive in the first situation, the possibility cannot be excluded that they contribute significantly to caries activity in modern human populations. The commonly used term "dietary starch content" is misleading, since it represents a large array of single manufactured and processed foods of widely varying composition and potential cariogenicity. Hence, increased focus on the cariogenicity of single starchy foods is warranted. Other aspects of starchy foods consumption, deserving greater attention, include the bioavailability of starches in processed foods, their retentive properties, also in relation to sugars present (starches as co-cariogens), their consumption frequency, the effect of hyposalivation on their cariogenicity, and their impact on root caries. The starch-caries issue is a very complex problem, and much remains uncertain. More focused studies are needed. At present, it appears premature to consider or promote food starches in modern diets as safe for teeth.

Abstract Objectives High consumption of starchy foods has been linked to increased risk of type 2 diabetes. Addition of food hydrocolloids gums to food has previously been shown to reduce the digestibility of food. Gellan gum, a polysacchairde produced by sphingomonas eldea is one of many available food hydrocolloid gums. The aim of the present study was to examine the effect of adding gellan gum to white rice during cooking on the starch digestibility and related in-vitro glycemic index(GI). Methods A static in-vitro digestion model was used based on the protocol from the INFOGEST static in-vitro simulation of gastrointestinal food digestion model (Brodkorb et al, .2019). Four different samples were prepared: (A) Cooked Jasmine rice; (B) Cooked Jasmine rice + 1% low acyl gellan gum, LAGG (KELCOGEL F, CPKelco); (C) Cooked long grain rice and (D) Cooked long grain rice + 1% LAGG. The oral phase was simulated by adding 5 ml of simulated salivary fluid containing human salivary amylase, followed by gastric phase and an intestinal phase. Glucose release was determined by Sugar Reduction Assay(PAHBAH) and compared to a maltose standard curve at consecutive time points for 2 hours. Results The addition of LAGG inhibited starch hydrolysis for both Jasmine and long grain rice. The greatest effect was observed for Jasmine rice. Starch digestion was reduced with the addition of LAGG to Jasmine rice by 27% and with the addition to long grain rice by 21% at 120 minutes. The GI was calculated using the area under curve and white bread as reference. The addition of LAGG to Jasmine rice reduced the GI value by 8% whilst the effect on long grain rice was less pronounced. Conclusions The addition of gellan gum to rice during cooking reduced starch digestion in white rice and the in-vitro glycemic index. This might be an effective way to reduce the glycemic response to starchy foods in human.

The aim: A study of the impact of drinking water quality on the state of dental health in schoolchildren who permanently live in areas of biogeochemical deficiency of fluorine and iodine. Material and methods: The composition of the drinking water of the city of Uzhhorod and the city of Rakhiv has been investigated. The prevalence and intensity of dental caries in children is determined, drinking water is taken in accordance with Uzhhorod and Rakhiv. Results: The regional features of the composition of drinking water of the mountain Rakhivsky district of the Transcarpathian region are the high variety of combinations of mineral components and the frequent excess of the normative content of dry residue components, namely nitrates, sulfates, chlorides, magnesium and calcium.Water oxidation, total stiffness and total alkalinity were significantly different. The established drinking water quality indicators have a direct dependence on the prevalence and intensity of dental caries in children, that is, a significant increase in the number of carious temporary, carious and distant permanent teeth and a decrease in filled temporary and permanent teeth (p < 0. 05) were diagnosed. Conclusions: One of the most pressing problems in water hygiene is the urgent need to review and improve regulations, State sanitary regulations, standards and other regulations in the field of drinking water, including through the development of regional drinking water quality standards.

For many decades, sugars have been the dietary constituents receiving the most attention in relation to their effects on dental caries. Frequently, however, there is little relationship between the amount of sugar in a food and its ability to induce caries. Therefore, it is clear that constituents in the diet can influence the ability of plaque to lower the pH of sugar solutions. For instance, replacing sugar in foods with xylitol, sorbitol, saccharin, oraspartamemay lead to areduction in the incidence of dental caries. All these sugar substitutes are non-cariogenic, and some may possess cariostatic properties. The presence of arginine-rich proteins in the diet may provide a ready source of this amino acid, which is the substrate for the arginine deiminase pathway which can result in a rapid elevation of plaque pH values. Proline can act as an acceptor for protons from lactate in the Stickland reaction. This is a major but much-neglected metabolic pathway in dental plaque. The presence of fat in experimental diets has been shown to affect their cariogenicity. The effects have been ascribed to enhanced clearance of sugars from the mouth. It is also conceivable that several fatty acids express a potent antibacterial effect. The presence of calcium and phosphorus has been shown to influence the cariogenicity of foods; the effect, however, is restricted to the food containing the minerals. Evidence suggests that pyridoxine (vitamin B6) may exert a cariostatic effect by enhancing decarboxylation activity in dental plaque. It is clear that sugar alone is not the sole determinant of whether food is cariogenic. Furthermore, myriad substances may hinder or enhance the caries-promoting properties of sugars in the diet.

Abstract Background Dental caries is still serious problem among Japanese children. Previous studies suggested that higher consumption of vegetables prevent dental caries. Eating order habit, such as eating vegetables at start of meal, called “Vege-first”, may increase the amount of vegetable consumption, and in turn, prevent dental caries. However, no published studies have examined the impact of “Vege-first” habit on dental caries. The aim of this study to investigate the association between “Vege-first” and dental caries among Japanese children. Methods We used the 2015 cross-sectional data from the Adachi Child Health Impact of Living Difficulty (A-CHILD) study, a population-based study of all first-grade students in Adachi City, Tokyo, Japan. The number of DMFT (decayed, missed due to decay, and filled teeth) was used as an outcome. Poisson regression analyses were applied to determine the independent association between “Vege-first” habit and the number of DMFT after controlling for the effects from child’s sex, parents’ marital status, socioeconomic status, and frequency of tooth brushing, drinking sweet beverages, and snacking. Results Of 3,689 valid Japanese children participants, 38.2% had DMFT and 11.6% were having the “Vege-first” habit. The number of DMFT decreased linearly with “Vege-first” habit (p &lt; 0.001). After controlled for covariates, the number of DMFT was still significantly and independently decreased with “Vege-first” habit (prevalence ratio=0.89 (95% confidential interval [0.81-0.98])). Conclusions This study showed that having the “Vege-first” habit was associated with dental caries even accounting for socioeconomic status, dental health behavior, and dietary habits. Health policy introducing “Vege-first” habit may be effective to prevent pediatric dental caries. Key messages Eating habit which vegetables at start of meal called “Vege-first” may increase the amount of vegetable consumption and possibly reduce dental caries. The habituation of Vege-first was likely to reduce child’s dental caries even accounting for socioeconomic status, dental health behavior and dietary habits.

AbstractThe aim of this study was to investigate the impact of oral hygiene, periodontal diseases, and dental caries on all-cause mortality in hemodialysis. This prospective cohort study included 266 patients with end-stage renal disease who were undergoing hemodialysis. Medical interviews, blood biochemical tests, and comprehensive dental examinations including periodontal pocket examination on all teeth and dental plaque accumulation by debris index-simplified (DI-S), were performed. Survival rates were assessed at a 3-year follow-up. Overall, 207 patients were included in the longitudinal analysis, and 38 subjects died during the follow-up period. Cox proportional hazards analysis of the multivariate model demonstrated that the highest tertile of DI-S had a significantly higher risk of all-cause mortality than the lowest two tertiles after adjustment for age, sex, smoking habit, body mass index, diabetes, prior cardiovascular disease, hemodialysis vintage, high sensitivity C-reactive protein, albumin, and number of remaining teeth (hazard ratio, 3.04; 95% confidence interval, 1.50–6.17; p = 0.002). Moreover, the number of decayed teeth significantly increased the hazard ratio to 1.21 (95% confidence interval, 1.06.1.37; p = 0.003). This study suggests that accumulated dental plaque and untreated decay, but not periodontal disease, may be independently associated with all-cause mortality in patients undergoing hemodialysis.

Obese women are more likely to have decreased insulin sensitivity and are at increased risk for many adverse pregnancy outcomes. An early lifestyle intervention (LI) may have the potential to reduce the impact of insulin resistance (IR) on perinatal outcomes. We report post hoc analysis of an open-label randomized control trial that includes IR women with body-mass index ≥25 randomly assigned to a LI with a customized low glycemic index diet or to standard care (SC) involving generic counseling about healthy diet and physical activity. Women were evaluated at 16, 20, 28, and 36 weeks of gestation, at which times perinatal outcomes were collected and analyzed. An oral-glucose-tolerance test (OGTT) showed that women in the LI group had lower plasma glucose levels at 120 min at 16–18 weeks of gestation, and at 60 and 120 min at 24–28 weeks. More importantly, these women had a lower rate of large-for-gestational-age (LGA) infants (p = 0.04). Interestingly, the caloric restriction and low-glycemic index diet did not increase the rate of small-for-gestational-age (SGA) babies in the LI group. A lifestyle intervention started early in pregnancy on overweight and obese women had the potential to restore adequate glucose tolerance and mitigate the detrimental role of IR on neonatal outcomes, especially on fetal growth.

Objective: To compare levels of dental caries, bacterial dental plaque, gingivitis, enamel defects, and caries-related microflora in children with and without craniosynostosis. Study group: Fifty-seven children with craniosynostosis and their matched controls. Outcome measures: The decayed, missing, and filled teeth and surfaces in both the deciduous (dmfs and dmft) and the permanent dentition (DMFS and DMFT). The plaque and gingivitis scores and developmental enamel defects were also recorded. The caries-related microflora was sampled using an alginate swab and the prevalence of Streptococcus mutans and Lactobacillus and Candida species were recorded. Results: The dmfs (p < .02) and dmft (p < .01) were significantly greater in the control children. The plaque score for the deciduous dentition only (p < .02) and also the gingivitis score for the permanent teeth only (p < .008) in the craniosynostosis group were significantly greater. The total aerobic bacterial count (p < .004), anaerobic count (p < .002), and Candida count (p < .05) were significantly greater in the control group. The proportion of S. mutans both as a percentage of the total anaerobic count (p < .04) and the total streptococcal count (p < .05) was significantly greater in the control group.

Abstract Aim The purpose of this study was to examine the impact of psychological states, self-rated oral health, and oral health behavior on hopelessness. Methods and Materials A cross-sectional study design was used. Data were collected between September and November 2006. The sample consisted of 233 Romanian adults (mean age 47.3 years; 65.6% women; 65.8% married). The questionnaire included information about demographic, psychological, self-reported oral health, and oral health related behavior items. Results ‘Hopeless’ participants were more likely to self-evaluate their dental health as poor/very poor (P<0.001), to be less satisfied by the appearance of their teeth (P<0.05), to report more non-treated caries (P<0.01), to brush their teeth less than twice per day (P<0.01), and never use mouthrinse (P<0.05). Logistic regression analysis showed ‘hopeless’ participants were apt to have a lower educational level, brush less frequently, have higher financial problems as the reason for not visiting the dentist, and report higher anxiety (odds ratio = 5.4, 4.2, 2.6, and 12.6, respectively). Forty-seven (73.4%) of 64 ‘hopeless’ participants and 90 (80.4%) of 112 ‘non-hopeless’ participants were correctly predicted by the above four variables. Conclusion The results of this study found impaired oral health and financial problems may pose an increased risk for hopelessness. Clinical Significance Poor oral health can be regarded as a risk marker for the level of hopelessness. Citation Dumitrescu AL, Kawamura M.
