Food starches and dental caries. (1/43)

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.  (+info)

Modern methods for assessing the cariogenic and erosive potential of foods. (2/43)

Assessment of the acidogenic and cariogenic erosive potential of foods requires the use of reproducible and standardised methods. The methodology laid down at the San Antonio conference in 1985 remain today the basis for research on and the testing of foods. The 1999 workshop has updated the appropriate methodology and introduced guidelines on the testing of erosive potential of foods. It is to be hoped that researchers wishing to evaluate foods and their effect on the teeth will continue to use these methods.  (+info)

Intake of sweet foods and counts of cariogenic microorganisms in obese and normal-weight women. (3/43)

OBJECTIVE: To study the intake of sweet foods in obese and normal-weight women, while also taking menstrual cycle effects on eating behaviour into consideration. An objective test of the intake of sugar-containing foods was introduced by measuring salivary counts of mutans streptococci and lactobacilli. DESIGN: A cross-sectional comparison of the intake of sweet foods in obese and normal-weight women. The obese women were also studied longitudinally after 10 weeks in a weight reduction programme. SUBJECTS: Obese (n=72, body mass index (BMI) 42.0+/-5.2 kg/m2) and normal-weight women (n=67, BMI 22.2+/-1.6 kg/m2) participated. RESULTS: Mutans streptococci in saliva were higher in obese than in normal-weight women (P<0.0001), although the reported habitual daily intake of sweet foods did not differ. Of the menstruating women, 80% of the obese subjects and 62% of the normal-weight ones (P<0.05) reported periods during the menstrual cycle with an 'extra large' intake of sweet foods; these intakes were higher in obese than in normal-weight women (P<0.01). The obese women reduced their intake of sweet foods after 10 weeks of weight reduction, although these changes were not pronounced enough to significantly affect the counts of cariogenic microorganisms. CONCLUSIONS: In contrast to most previous cross-sectional studies, this study shows that obese women have a higher intake of sweet foods, especially pre-menstrually. This was indicated by higher salivary counts of cariogenic microorganisms. SPONSORSHIP: Karolinska Institute Research Funds.  (+info)

A mixed-bacteria ecological approach to understanding the role of the oral bacteria in dental caries causation: an alternative to Streptococcus mutans and the specific-plaque hypothesis. (4/43)

For more than 100 years, investigators have tried to identify the bacteria responsible for dental caries formation and to determine whether their role is one of specificity. Frequent association of Lactobacillus acidophilus and Streptococcus mutans with caries activity gave credence to their being specific cariogens. However, dental caries occurrence in their absence, and the presence of other bacteria able to produce substantial amounts of acid from fermentable carbohydrate, provided arguments for non-specificity. In the 1940s, Stephan found that the mixed bacteria in dental plaque produced a rapid drop in pH following a sugar rinse and a slow pH return toward baseline. This response became a cornerstone of plaque and mixed-bacterial involvement in dental caries causation when Stephan showed that the pH decrease was inversely and clearly related to caries activity. Detailed examination of the pH (acid-base) metabolisms of oral pure cultures, dental plaque, and salivary sediment identified the main bacteria and metabolic processes responsible for the pH metabolism of dental plaque. It was discovered that this metabolism in different individuals, in plaque in different dentition locations within individuals, and in individuals of different levels of caries activity could be described in terms of a relatively small number of acid-base metabolic processes. This led to an overall bacterial metabolic vector concept for dental plaque, and helped unravel the bacterial involvement in the degradation of the carbohydrate and nitrogenous substrates that produce the acids and alkali that affect the pH and favor and inhibit dental caries production, respectively. A central role of oral arginolytic and non-arginolytic acidogens in the production of the Stephan pH curve was discovered. The non-arginolytics could produce only the pH fall part of this curve, whereas the arginolytics could produce both the fall and the rise. The net result of the latter was a less acidic Stephan pH curve. Both kinds of bacteria are numerous in dental plaque. By varying their ratios, we were easily able to produce Stephan pH curves indicative of different levels of caries activity. This and substantial related metabolic and microbial data indicated that it is the proportions and numbers of acid-base-producing bacteria that are at the core of dental caries activity. The elimination of S. mutans, as with a vaccine, was considered to have little chance of success in preventing dental caries in humans, since, in most cases, this would simply make more room for one or more of the many acidogens remaining. An understanding of mixed-bacterial metabolism, knowledge of how to manipulate and work with mixed bacteria, and the use of a bacterial metabolic vector approach as described in this article have led to (1) a more ecological focus for dealing with dental caries, and (2) new means of developing and evaluating anti-caries agents directed toward microbial mixtures that counter excess acid accumulation and tooth demineralization.  (+info)

Do we need to be concerned about dental caries in the coming millennium? (5/43)

Dental caries continues to be a pubic health problem despite claims that 50% of schoolchildren are caries-free. There are widespread variations in the prevalence of caries worldwide. Caries lesions are the clinical manifestation of a pathogenic process that may have been occurring on the tooth surface for months or years. Acid production by bacteria embedded in a biofilm termed "dental plaque" is a key aspect of the pathogenesis of dental caries; nevertheless, the ability of micro-organisms to survive in a hostile acid milieu and the influence of fluoride and additional agents on this acid tolerance receive scant attention. Study of cariogenic micro-organisms largely has been limited to observations made on them in the planktonic state; clearly dental caries is essentially a surface phenomenon, and micro-organisms behave distinctively when grown on a surface. Although significant progress has been made in our understanding of the etiology, pathogenesis, and prevention of dental caries, it still remains a scientific and clinical enigma worthy of the attention of the best scientists.  (+info)

Effect of a Brazilian regional basic diet on the prevalence of caries in rats. (6/43)

The aim of the present study was to determine the effect of a regional basic diet (RBD) on the prevalence of caries in the molar teeth of rats of both sexes aged 23 days. The animals were divided into six groups of 10 rats each receiving the following diets for 30 and 60 days after weaning: RBD, a cariogenic diet, and a commercial diet. The prevalence and penetration of caries in the molar teeth of the rats was then analyzed. The RBD produced caries in 37.5% of the teeth of animals fed 30 days, and in 83.4% of animals fed 60 days, while the cariogenic diet produced caries in 72.5% and 77.5% of the teeth of animals fed 30 and 60 days, respectively. Rats fed the RBD for 30 days had caries in the enamel in 38% of their teeth, 48% had superficial dentin caries, and 7.5% moderate dentin caries. The effect of the RBD did not differ significantly from that of the cariogenic diet in terms of the presence of caries in rats fed 60 days. The penetration depth of the caries produced by the RBD was the same as that produced by the cariogenic diet. Our results show that the RBD has the same cariogenic potential as the cariogenic diet. Since the RBD is the only option for the low-income population, there should be a study of how to compensate for the cariogenicity of this diet.  (+info)

Genome sequence of Streptococcus mutans UA159, a cariogenic dental pathogen. (7/43)

Streptococcus mutans is the leading cause of dental caries (tooth decay) worldwide and is considered to be the most cariogenic of all of the oral streptococci. The genome of S. mutans UA159, a serotype c strain, has been completely sequenced and is composed of 2,030,936 base pairs. It contains 1,963 ORFs, 63% of which have been assigned putative functions. The genome analysis provides further insight into how S. mutans has adapted to surviving the oral environment through resource acquisition, defense against host factors, and use of gene products that maintain its niche against microbial competitors. S. mutans metabolizes a wide variety of carbohydrates via nonoxidative pathways, and all of these pathways have been identified, along with the associated transport systems whose genes account for almost 15% of the genome. Virulence genes associated with extracellular adherent glucan production, adhesins, acid tolerance, proteases, and putative hemolysins have been identified. Strain UA159 is naturally competent and contains all of the genes essential for competence and quorum sensing. Mobile genetic elements in the form of IS elements and transposons are prominent in the genome and include a previously uncharacterized conjugative transposon and a composite transposon containing genes for the synthesis of antibiotics of the gramicidin/bacitracin family; however, no bacteriophage genomes are present.  (+info)

Composition of dental plaque formed in the presence of sucrose and after its interruption. (8/43)

Since dental plaque reservoirs of fluoride (F), calcium (Ca) and inorganic phosphorus (Pi) are susceptible to decreases in pH, this in situ crossover study was conducted to test the hypothesis that the low concentration of these ions in plaque, formed in the presence of sucrose, could be attributed merely to the fermentation of this sugar. Eleven volunteers wore palatal appliances containing 6 human enamel blocks during two stages. In each stage, the treatments were either 20% sucrose solution or distilled deionized water, which were dripped onto the blocks 8 times a day. After 28 days, in each stage, the dental plaque formed on two blocks was collected, the treatment was inverted and after a further 24 and 48 h, the biofilm formed was collected from the other blocks. The concentration of acid-soluble F, Ca and Pi, and the concentration of insoluble polysaccharide (IP) were determined in the dental plaque. Statistically lower concentrations of F, Ca and Pi, and a higher concentration of IP were found in the 28-day biofilm formed in the presence of sucrose than in its absence; after the treatment inversion the change in F, Ca and Pi was not statistically significant, but the IP concentration changed significantly. The hypothesis was rejected because change in concentration of F, Ca and Pi is not due to fermentation of the sucrose.  (+info)

NaturalNews) Two new studies showing that vaccines increase the risk of diabetes have been published in the Open Pediatric Medicine Journal.. In a prior study, published in the journal Autoimmunity, Dr. J. Bartholomew Classen of Classen Immunotherapies and David Carey Classen of the University of Utah compared more than 100,000 children who had received between one and four doses of the hemophilus vaccine with more than 100,000 unvaccinated children. The Classens found that after seven years, children in the vaccination group had a 26 percent higher risk of developing diabetes than children in the non-vaccine group. This amounted to an extra 54 cases of diabetes per 100,000 children vaccinated.. The Classens noted that the vaccine itself is only projected to prevent seven deaths and seven to 26 cases of permanent disability per 100,000 children.. "Our results conclusively prove there is a causal relationship between immunization schedules and diabetes," J. Bartholomew Classen said at the time. ...

Pediatric healthcare systems in both the United States and Canada are facing unique challenges in serving children and maintaining centres of excellence. These challenges stem from, but are not limited to, inadequate government-issued health research funding; the demand to provide excellent care with, at times, limited resources; and patients access to care. They are also due to the discrepancy between the technology that is being developed in the biomedical field and the lack of translation that is seen from this innovation to pediatric medicine.

The pH meter measures the pH of a solution using an ion-selective electrode (ISE) that responds to the H+ concentration of the solution. The pH electrode produces a voltage that is proportional to the concentration of the H+ concentration, and making measurements with a pH meter is therefore a form of potentiometry. The pH electrode is attached to control electronics which convert the voltage to a pH reading and displays it on a meter. ...

Food and drink for diabetics. Important stuff this the message is again spelt out with lancet caps in the same way as sequence 7. Having discussed the animation with healthcare professionals it is apparent they think the important parts of their message must not be overlook but be emphasised. What better way to do it (largely for their benefit) can there be to than writing it out clear and slowly in block capitals. "SWEET FOOD CONTAINS GLUCOSE!". (Even so, there was quite a long debate over the precise wording such simple phrase of this).. When I came to make a start in the morning it had rained over night and humidity in the air seems to wrapped the paper stretched out on the board. In fact this whole part has proved immensely frustrating.. Because the original file of photographs is too late to be processed by Photoshop it had to be broken down into three separate parts.

Adjust to pH 7.60 with concentrated HCl (about 0.5-0.7 mL/L). Rinse the bulb of the pH meter with DI H2O and check the pH meter using one of the standards. Rinse the bulb again and hold it in the medium while slowly adding HCl using a pipette. Press "Read" to get the new pH. When the medium is at pH 7.60, rinse off the pH meter again. Make sure to adjust the pH, or the salt will come out of solution ...

How about the part where your government, as well as Canadas, regularly sends people to other countries to get treatments they cant provide? In the US, we get a fairly regular influx of NICU babies from Canada, because in parts of Canada there are only open NICU beds about 50% of the time.". Just curious - do you kno how many of those are being sent to the US because Canadas system sucks (which seems to be your contention) versus because no place has an infinite number of beds? I mean, babies get flown all over *within* the US for the same reason. There are whole charities which have sprung up to help parents whose families have been uprooted so they can accompany their children to remote hospitals. The Ronald McDonald House is probably the most visible of these charities.. Bottom line is that kids get flown all over *anyway*. Ive never seen a good breakdown of how much this is due to just the nature of pediatric medicine and how much this is due to lack of capacity abroad. (It is worth ...
Emotional needs - One of the reasons people crave sweet foods is because they crave some "inner" sweetness in life. Meal times are a way to connect and bond with family members, making people feel "filled" with love, care, and fun. However, some people spend their mealtimes alone, which may be the reason they have an "inner" need for sweetness. In turn, they search for other ways to fulfill this need, which is through sweet foods. Some people also crave sweet foods because they are used to using sweet treats as a reward. Meanwhile, others crave sweets because they cant process their emotions. As a result, they tend to overeat when they are feeling emotional because they have associated sweet flavors with comfort from childhood ...

RIVERSIDE, Calif. - Insects represent remarkable diversity and have adapted to all sorts of ecological nooks and crannies. For example, they have taste receptors - novel proteins - with which they taste chemicals and make important choices about not only foods but also mates and where to deposit their eggs.
Lets walk through an example. Things start out with a diet. By diet I mean you do some combination of eating less and exercising more. In the beginning you seem to be doing great. You lose a few pounds right off the bat. So far so good.. Now youre a week or so in and you start feeling hunger, your energy falls, and you find yourself craving salty, fatty and sweet foods. This is a sign the body is starting to move into metabolic compensation. Think of this as Starvation Mode Level 1.. Because of this compensation you notice that your fat loss slows down. Perhaps it halts all together. And if youre one of those people that has a very pronounced metabolic decline you may notice you even start gaining weight. And the hunger, energy, and craving issue keeps getting worse.. But youre not playing games. You pride yourself on your iron will and rock-solid work ethic. You double your efforts by cutting calories further and ramping up your gym time. Nice. Now youre getting some movement again. ...
Cystinuria is a disease of autosomal recessive inheritance. This disease belongs to the so-called orphan diseases although its prevalence may change depending on the country.. It is known that urinary pH is a risk factor for the formation of cystine crystals because their solubility is pH-dependent. In different studies it has been shown that the solubility of cystine in urine increases when alkalinizing urinary pH, thus reducing the likelihood of crystal formation. Therefore, the control of urinary pH along with hygienic-dietetic measures that alkalize the urine or decrease the urinary concentration of cystine (abundant intake of water, food, etc.) are highly recommended as a preventive method to prevent the formation of cystine crystals whose retention and growth results in the formation of stones.. The Lit-control®pH Meter is a pH meter that allows a patient to self-monitor its urinary pH in a comfortable and simple way. With this tool the patient is able to know if his urinary pH is within ...

Low birth weight and premature delivery predispose infants to the need for resuscitative efforts.. Indications Neonate with the following:. ...

We have reported that neonatal handling leads to increased sweet food preference in adult life. Our aim was to verify if these differences in feeding behavior appear before puberty, and whether other types of intervention in periadolescence (such as exposure to toys) could interfere with sweet food consumption later in life. Nests of Wistar rats were (1) non-handled or (2) handled (10 min/day) on days 1-10 after birth. Males from these groups were subdivided in two subgroups: one was habituated to sweet food (Froot Loops-Kellogs) in a new environment for 4 days and tested for sweet food preference at age 27 days, before submitting to a new habituation and test for sweet food ingestion again in adult life ...
NPR published a story on the dangers of ineffective measurements. Pediatric medicines require specific doses. This is because kids come in all different sizes and side effects can cause serious problems. But because kids dont like to swallow pills (even mixed up in apple sauce), many medicines are give as liquids. Cough syrup, Tylenol, and Vancomycin all have versions as oral solutions. So how much are you supposed to give the kid? A teaspoon? Tablespoon? This can be a very important detail that leads to drastically different outcomes. Studies show that neither teaspoon nor table spoon should be the best answer. They are unreliable can mess up a childs therapy ...
Current dosing is based on a childs weight in some cases, and a childs age in others. The authors argue this makes it confusing for physicians, resulting in underdosing. Thats when a child fails to receive a large-enough dose to kill the harmful bacteria causing their illness. It can happen when a childs weight is higher than average for their age.. "Based on the results of oral dosing studies conducted using the scheme for penicillin G described at the conference, a general recommendation to use age banding for all antibiotics in children, irrespective of the type of penicillin or disease indication, was published in the BMJ in 1963," reads the piece. "Critically, these recommendations have remained unchallenged and unchanged to this day.". "Its much more appropriate to dose by weight," Dr. Jeremy Friedman, pediatrician and head of the division of pediatric medicine at SickKids in Toronto. However, he says some physicians who treat children - but who dont focus on them exclusively - may ...

In spite of the improve during the use of M&S as tools for decision-making in pharmaceutical R&D, their benefits as an optimisation and data analysis tool has remained undervalued and sometimes ignored by key stakeholders . This attitude appears contradictory to ethical and scientific tenets, which should underpin the evaluation of the risk?benefit ratio in special populations, such as children. The ethical constraints and practical limitations associated with clinical research clearly impose new alternative methodology to ensure accurate assessment of treatment response in these patients. In that sense, the value of M&S to paediatric research may be even greater than the evidence available so far for drug development in adults. The interest in M&S is also reaching the attention of the regulatory authorities. In April 2008, the European Medicines Agency organised a "Workshop on Modelling in Paediatric Medicines" . More recently, Silmitasertib selleckchem M&S have been proposed as a framework for ...
Ionic charges work in the same way as magnets and opposites attract, so the amount of molecules that this happens to in pure water is relatively low - only 1 in 555million water molecules stays separated in this way, and as there is nothing else in the solution for the ions to bind to, the number of H+ equals the number of OH-. This gives pure water a pH of 7, and other solutions are compared to this. When the water is impure (has things mixed into it) the ionic balance is disrupted - either the OH- or the H+s will bind to the molecules within the solution and leave an excess of the other. Due to the nature of the calculation giving us pH, as the concentration of H+ increases, the pH decreases, so the more acidic a solution, the lower the pH ...
