RESUMO

The foods in the diet contain a wide range of organic and inorganic compounds. Considering these from an elemental perspective, 5 so-called macroelements, calcium, potassium, sodium, phosphorus and chlorine, are contained in comparatively large quantities in foods compared to all other elements. This chapter attempts to review the importance of these dietary macroelements on oral health, and in particular their role in tooth loss, dental caries, erosive tooth wear and periodontal disease. Calcium and phosphate make up the bulk of the mineralized human tissues. Adequate intake of both is therefore of crucial importance in maintaining the health, function and retention of teeth and bones. Supplementation of the diet with calcium has also been shown to aid in maintaining and improving oral health. Several attempts have been made to lessen the erosive potential of beverages through calcium supplementation. Adequate calcium intake is also crucial for maintaining periodontal health. In many areas, however, the evidence is still emerging or controversial. Phosphate supplementation of the diet was once thought to decrease caries incidence, although studies in children were not successful. Furthermore, little attention has been paid to the other macroelements, highlighting the need for more well-controlled and comprehensive studies.

RESUMO

An improvement in oral health, not least dental caries and periodontal disease, has been seen during the last 50 years. Oral health is essential for both general health and quality of life. The mouth is a window into the health of the body and signs of nutritional deficiencies can be seen in the mouth at an early stage. Dental caries still constitutes the most common oral condition worldwide. It is the net result of an ecological imbalance in the oral biofilm where metabolism of fermentable carbohydrates may result in demineralisation. Early diagnosis of disease symptoms and preventive strategies are important for disease management. Dental erosion, where loss of tooth substance is a result of exposure to acidic substances, has become a common condition. Intrinsic factors, including diet/drinks and intake habits, are common etiological causes. Periodontal diseases constitute chronic, biofilm-initiated inflammatory conditions with multifactorial origin including inherited and acquired risk factors. Preventive strategies focus on mechanisms, which may influence the amount and composition of the subgingival biofilm. Oral cancer is one of the most commonly found forms of malignancies worldwide. It is a highly complex condition where lifestyle factors, particularly smoking cessation and moderate alcohol consumption, play a major role as deterrents. Hyposalivation is of multifactorial aetiology and may influence oral health as well as various aspects of quality of life. To control oral health, it is important to increase our knowledge of oral disease aetiology and focus on oral health promotion and preventive strategies including the control of diet and nutritional risk factors.

RESUMO

The World Health Organization has defined probiotics as "Live microorganisms which, when administered in adequate amounts, confer a health benefit to the host." Traditionally, probiotic microorganisms (mainly Lactobacillus ssp. and Bifidobacterium ssp.) have been used to prevent or treat diseases in the gastrointestinal tract. In the past 20 years, there has been an increased interest in possible oral health effects of probiotics. In vitro studies have shown promising results with growth inhibition of mutans streptococci (MS) and Candida albicans. There are only a few clinical studies with caries development as the primary outcome while more studies have been focusing on control of caries risk factors or so-called surrogate outcomes. Several studies have evaluated the effects of probiotic bacteria on MS in saliva and/or plaque, and a number of probiotic strains show ability to reduce the number of MS. Probiotic bacteria have not been shown to permanently colonize the oral cavity; in early-in-life interventions or in subjects with a mature microbiota. To date investigated strains are transiently present in saliva during and shortly after an intervention. There are eight randomized controlled clinical trials with dental caries as outcome and probiotic strains, administration, duration of the intervention, and target group varied. In a majority of the studies (75%), the interventions resulted in caries reduction in the treatment groups. Although a majority of these studies suggest a caries-preventive effect of probiotic bacteria, more long-term clinical studies are needed in this field before probiotics could be recommended for preventing or treating dental caries.

RESUMO

Milk is an important part of the human diet; after weaning, cow's milk (bovine milk) predominates and this chapter considers the effect of bovine milk on dental caries. Yoghurt, which is a milk product, is also considered here. Several published reviews have concluded that milk is of very low cariogenicity and may have some caries protective potential. For example, WHO reviewed the strength of the evidence in 2003 and concluded that a "decreased risk" of dental caries from milk was "possible." The evidence comes from several types of study: epidemiological studies (interventional and observational), animal experiments, plaque pH studies, and in vivo and in vitro enamel and dentine slab experiments. More recent observational epidemiological studies have adjusted for potential confounders and have reported that milk consumption is associated with lower caries experience or incidence. Other types of study generally support this conclusion. Reasons for these favourable caries-related properties include the lower acidogenicity of lactose compared with other dietary sugars and the protective effects of calcium, phosphate, proteins, and fats. There is less research concerning yoghurts but it is likely that the cariogenic potential of plain yoghurt is similar to that of milk. The addition of sucrose to milk increases caries risk.

RESUMO

Ultratrace element is a relatively new term, and is defined as those elements with an established, estimated, or suspected dietary requirement of minute amount, generally of the order of µg/day. This chapter focuses on fluorine (F), aluminium (Al), molybdenum (Mo), and cobalt (Co). Whilst diet is the principal source of Al, Mo, and Co found in the body, inadvertent ingestion of dental hygiene products accounts for a significant proportion of F intake. Apart from F, the influence of other ultratrace elements on oral health, and in particular dental caries, has not been fully established. The calcified tissues contain 99% of body F. During tooth development, ingested (systemic) F is incorporated into the apatite crystals of the developing tooth which helps in improving resistance to acid demineralisation. However, the presence of low but constant levels of topical F in the fluid phase at the tooth enamel surface are more important in controlling tooth decay in people of all ages. An adequate intake, from all dietary and non-dietary sources, is estimated as 0.05 mg/kg body weight/day for children older than 6 months and adults, based on estimated intakes that have been shown to reduce the incidence of dental caries while minimising adverse health effects such as dental fluorosis. An inverse relationship between incidence of dental caries and levels of Al in drinking water, food, and soils has been indicated by some epidemiological studies. Co and Mo, whilst occasionally showing potential beneficial oral health effects in laboratory experiments, do so at concentrations much higher than found in vivo.

RESUMO

Sugar is added to food for a multitude of functions: fermentation, preservation, physical and chemical, and also to satisfy the consumer's preference for sweetness. Unfortunately, sugar consumption is also a main aetiological factor for dental caries. The relationship between sugar and caries was established in the latter half of the 19th century. Many factors influence this relationship: the availability of sugar for bacterial digestion, the presence of acidogenic bacteria in the plaque on teeth, and the ability of fluoride and saliva to counteract bacteria and acids. The importance of the frequency of administering sugars over the amount has been demonstrated in various studies in humans. Through guidelines, world and national health organizations advocate the reduction of sugar consumption to below 10E% (daily dietary energy percentage consumption per capita), but voluntary implementation on an individual basis is difficult for many, and maybe more compulsory strategies that aim to reduce both the amount and frequency of sugar intake are needed.

RESUMO

Diet and nutrition are fundamental in maintaining the general and oral health of populations. Diet refers to the total amount of food consumed by individuals; whereas nutrition is the process of utilising food for growth, metabolism and repair of tissues. The relationship between diet and nutrition and health is 2-way; health status can be affected by nutrient deficiency and vice versa. Dietary guidelines have been developed to provide evidence-based food and beverage recommendations for populations; aiming to promote a diet that meets the nutrient requirement, and to prevent diet-related diseases such as dental caries and obesity. Based on the amount required by the human body for normal metabolism, growth and physical well-being, nutrients are divided into 2 categories: macronutrients consisting of proteins, carbohydrates and fat; and micronutrients consisting of vitamins and minerals. Fats are the most energy-dense macronutrient; whereas carbohydrates are quantitatively the most important dietary energy source for most populations. Proteins are vital structural and functional components within every cell of the body and are essential for growth and repair and maintenance of health. Vitamins and minerals, which are found in small amounts in most foods, are essential for normal metabolic function. This chapter provides an overview of the impact of nutrients on general and oral health, with an emphasis on macronutrients.

RESUMO

Microelements are essential components of the diet. This chapter describes the effect of several such elements: zinc, copper, iron, tin, and iodine, on oral health. As part of normal diets, these elements have limited associations with specific oral conditions. This is partly because of their presence at relatively low concentrations and partly because they are most often present as mixtures where the effect of any one element is confounded by others. Deficiencies in microelements can cause health problems. Hence supplements, often containing one or more microelements, are prescribed to combat such conditions. All these ions exhibit antibacterial properties. Such effects are invariably small at the concentrations found in conventional foods and drinks. However, at higher concentrations, these ions can inhibit acid production by plaque bacteria involved in dental caries. Of more importance, zinc and tin have potentially significant effects on the de- and remineralisation processes involved in dental caries. Indeed, both elements have been included in oral hygiene products such as toothpastes for many years. Zinc, in particular, has demonstrated not only the ability to reduce dissolution rates of enamel and hydroxyapatite but also to inhibit calculus formation. Tin can also markedly reduce the dissolution rates. Both Cu and Fe have demonstrated anti-caries effects in animal models, whilst Fe-containing drinks have been shown to reduce enamel erosion in situ. The broad spectrum antibacterial properties of iodine have been promoted for its potential use against both early childhood caries and chronic periodontitis. However, more convincing clinical research is required to validate efficacy.

RESUMO

BACKGROUND: Radiotherapy is widely used in contemporary head and neck cancer treatment protocols. The ability of head and neck radiotherapy (HNRT) to cause direct radiogenic destruction to the teeth is one of the most controversial topics in the field of oral oncology. Therefore, this systematic review aimed to investigate ionising radiation as an independent factor for physical and chemical changes on the dentine-enamel junction (DEJ), a pivotal dental topography for the onset and progression of radiation-related caries (RRC) and enamel delamination. MATERIAL AND METHODS: Systematic searches were conducted on three databases: Scopus, MEDLINE (Via PubMed) and Embase (Elsevier). Laboratory studies evaluating the effects of simulated or in vivo HNRT on the DEJ were included. The GRADE tool adapted for in vitro studies was used to assess the methodological quality. RESULTS: Of the 154 initially selected studies, eight met the inclusion criteria, from which five studies were graded as high quality of evidence, two studies were graded as moderate quality and one as low quality. Two studies did not demonstrate DEJ alterations following HNRT while the other six articles described several organic and inorganic changes in the DEJ of irradiated teeth samples. These radiogenic events were mostly detected through micro and nanoindentation, Raman micro-spectroscopy, confocal microscopy, Western blotting and optical coherence tomography. CONCLUSIONS: HNRT may have a negative impact on the physical and chemical aspects of the DEJ, predisposing cancer patients to RRC and enamel delamination.

RESUMO

BACKGROUND: Although, peripheral caries (PC) affects almost half of UK horses, no comprehensive microbiological study has been performed on this disorder. As a high proportion of oral bacteria cannot be conventionally cultured, molecular microbiological techniques such as Next Generation Sequencing are required to examine the complex oral bacteria community. OBJECTIVES: To identify the microbiota involved in equine PC, including comparing microbiota at the more commonly and severely affected three caudal cheek teeth with the less commonly affected three rostral cheek teeth. STUDY DESIGN AND METHODS: Equine dental plaque samples were collected from the palatal aspects of cheek teeth of 63 horses. DNA was isolated and amplified using PCR, targeting the V4 region of the 16S rRNA gene and Next Generation Sequencing of these gene amplicons was performed. The acquired data were processed and analysed using Mothur and R. RESULTS: Streptococcus species was the genus most commonly associated with equine PC, whereas Gemella species was the genus most associated with the control group. In a further analysis where the rostral and caudal cheek teeth were compared with each other and with the control group. Veillonella species was the most commonly associated genus with PC of the rostral cheek teeth, Streptococcus species was the most associated genus with the caudal cheek teeth, and Corynebacterium with the control group. MAIN LIMITATIONS: Some bacteria can have multiple heterogeneous copies of the 16S rRNA gene, which can affect the estimation of their relative abundance. CONCLUSIONS: Similar to caries studies in other species, acidogenic and aciduric microorganisms including Streptococcus species were found to be associated with equine peripheral caries.

RESUMO

BACKGROUND: Peripheral caries (PC) has recently been shown to affect over half of UK and Australian horses. OBJECTIVES: To examine affected cheek teeth histologically and ultrastructurally, to assess the possible route(s) of carious infection into the dental tissues and to further describe the pathological changes in affected teeth. STUDY DESIGN: Descriptive pathological study. METHODS: Four control and 16 cheek teeth with different grades of PC were examined grossly, histologically and by electron microscopy. RESULTS: Cariogenic bacteria from plaque entered peripheral cementum perpendicular to the sides of teeth alongside Sharpey's fibres or vascular channels or more horizontally alongside exposed intrinsic fibres and cemental growth lines. Subsequent intra-cemental bacterial spread created different patterns of caries including vertical and horizontal flake-like patterns; deep, large flask-shaped or smaller superficial ellipsoid-shaped lytic lesions. Cemental caries progressed to affect enamel, dentine and even pulp. Gross examination underestimated the degree of caries observed on histological evaluation. MAIN LIMITATIONS: No dental histories were available; all teeth were examined on a single occasion. CONCLUSION: Equine PC causes different patterns of cemental lesions that appear dependent on the route of cariogenic bacterial invasion. Progression of caries can lead to pulpitis and tooth loss. Gross examination can underestimate the true extent of caries.

RESUMO

OBJECTIVE: The aim of this study was to observe the effect of V. parvula on the physiological activity of S. mutans and elucidate the role of V. parvula on dental caries. DESIGN: We constructed dual-species biofilms formed by V. parvula and S. mutans, and measured the pH dynamics, biofilm growth, Extracellular Polysaccharide (EPS) synthesis, and expression of S. mutans EPS synthesis-associated genes affected by V. parvula. RESULTS: pH dynamics were not altered when V. parvula and S. mutans were co-cultured during a 120 -h test period. However, S. mutans cell number and EPS synthesis in dual-species biofilms were found to be significantly higher than in single-species biofilms. Moreover, expression levels of genes encoding glucosyltransferases (gtfs), gtfB and gtfC specifically, were up-regulated when S. mutans was co-cultured with V. parvula. CONCLUSIONS: Our findings indicate that V. parvula is not, as previously thought, protective and associated with caries health. On the contrary, V. parvula might participate in caries development through interactions with S. mutans. This study suggests that V. parvula may have an impact on the pathogenesis of dental caries.

RESUMO

OBJECTIVE: To compare dental caries frequency in the Croatian population exhumed from two archeological periods and compare two methods: International Caries Detection and Assessment System (ICDAS) and DMFT (Decayed-Missing-Filled-Tooth) index. MATERIALS AND METHODS: The study included 279 teeth from 69 human remains: Set I of 30 remains and 126 teeth dated from 9th to10th centuries A.D. and Set II of 39 remains and 153 teeth from the recent 20th century. Methods used for caries prevalence were ICDAS and DMFT. Tooth wear was recorded according to the Brabant index. RESULTS: ICDAS scoring system showed significantly higher caries frequency in Set I of 64.34% and in Set II 59.47%, compared to DMFT method with 16.52% for Set I and 28.75% for Set II. Dental wear in Set I showed 73.91% and in Set II 73.15%, so no significant difference was observed. CONCLUSIONS: Depending on the ICDAS or DMFT method used for caries detection, different results have been obtained whereby the ICDAS system has a more precise and advanced approach for caries lesions.

RESUMO

OBJECTIVE: Description of the odontoblast lifecycle, an overview of the known complex molecular interactions that occur when the health of the dental pulp is challenged and the current and future management strategies on vital and non-vital teeth. METHODS: A literature search of the electronic databases included MEDLINE (1966-April 2019), CINAHL (1982-April 2019), EMBASE and EMBASE Classic (1947-April 2019), and hand searches of references retrieved were undertaken using the following MESH terms 'odontoblast*', 'inflammation', 'dental pulp*', 'wound healing' and 'regenerative medicine'. RESULTS: Odontoblasts have a sensory and mechano-transduction role so as to detect external stimuli that challenge the dental pulp. On detection, odontoblasts stimulate the innate immunity by activating defence mechanisms key in the healing and repair mechanisms of the tooth. A better understanding of the role of odontoblasts within the dental pulp complex will allow an opportunity for biological management to remove the cause of the insult to the dental pulp, modulate the inflammatory process, and promote the healing and repair capabilities of the tooth. Current strategies include use of conventional dental pulp medicaments while newer methods include bioactive molecules, epigenetic modifications and tissue engineering. CONCLUSION: Regenerative medicine methods are in their infancy and experimental stages at best. This review highlights the future direction of dental caries management and consequently research.

RESUMO

Neste caso, a orientação e motivação dos pais/responsáveis assume papel importantíssimo, tanto para o retorno às consultas, quanto para o controle dos fatores de risco para a cárie precoce na infância. Os pais/responsáveis devem ser orientados em relação à dieta, especialmente a suspender a mamadeira assim que a criança seja capaz de beber em uma xícara/copo. Devemos também alertar sobre o efeito das mamadas noturnas nos dentes dos bebês e desencorajar o uso de mamadeiras e chupetas açucaradas(1,2).

RESUMO

The objective of this study was to investigate the experience of caries related to social capital and associated factors in adults in large-scale population-based study. A Cross-sectional study was performed in 163 municipalities in the State of São Paulo, Brazil (SBSP-2015). 17,560 people were evaluated, of which 6051 were adults aged 35-44 years. Hierarchical logistic regression analysis was proposed. Outcome variables (decayed teeth, missing teeth and DMFT) and independent variables were included in the model, considering the distal (income and schooling); intermediate (social capital) and proximal levels (sex and ethnicity). Results showed that income up to 1,500 reais - US$ 367.6 in 11/11/2019 - (OR = 1.91;1.75-2.08), schooling up to 8 years (OR = 1.32;1.12-1.56) and non-white ethnicity (OR = 1.54;1.35-1.76) were more likely to have decayed teeth. Income up to 1500 reais (OR = 1.29;1.15-1.44), schooling up to 8 years (OR = 2.13;1.90-2.38), low social capital (OR = 1.84;1.65-2.04), medium social capital (OR = 1.15;1.01-1.30) and females were more likely to have lost teeth (OR = 1.13;1.03-1.23). Schooling up to 8 years (OR = 1.51;1.35-1.69), low social capital (OR = 1.25; 1.14-1.37) and female (OR = 1.40,1.19-1.53) were associated with DMFT. It was concluded that sociodemographic factors and low social capital were associated with the experience of caries, which should be taken into account in the formulation of public policies.

RESUMO

El diagnóstico de caries dental ya no es más como el diagnóstico tradicional que mencionaba histológicamente el inicio y el final de una cavidad. Se ha demostrado que los criterios de diagnóstico y las herramientas utilizadas en la detección de lesiones de caries afectan la toma de decisiones para su tratamiento. Hoy en día, la caries dental es considerada un proceso; por ello, en el presente artículo, se describen nuevas propuestas que nos ayudarán con el diagnóstico, manejo y control de dicha enfermedad. Los criterios Cambra e Icdas son los que teóricamente tienen sustento bajo evidencia científica de lo que es actualmente la patología y su desarrollo, por lo que se describen los antecedentes históricos de su desarrollo, sus principales características, y se proponen opciones de integración al proceso diagnóstico actual a favor de una mayor conservación de la estructura dentaria. (AU)


The diagnosis of dental caries is no longer like the traditional diagnosis that histologically mentioned at the beginning and end of a cavity. It has been shown that the diagnostic criteria and tools used in the detection of caries lesions affect the decision-making process for caries treatment. Today tooth decay is considered as a process; That is why in this article new proposals are presented that will help us with the diagnosis, management and control of said disease. The criteria Cambra and Icdas, are those that theoretically have sustenance under scientific evidence of what is currently the pathology and its development; Therefore, the historical background of the development of Cambra and Icdas, its main characteristics are described, and integration options are proposed to the current diagnostic process in favor of greater preservation of the dental structure.

RESUMO

Purpose: Primarily, to analyze how application of silver diamine fluoride (SDF ) impacts the odds of presenting to urgent care (UC ) while awaiting dental treatment under general anesthesia (GA ). Secondarily, to analyze descriptive data from UC visits to identify trends associated with a prolonged GA wait time.
Methods: Retrospective chart audit of a sample of patients on the GA waitlist for complete oral rehabilitation from January 1st, 2014 to December 31st, 2016. Data points collected include total GA wait time, SDF application, UC presentation, number of encounters, chief complaint and treatment. Age, dmft, sex, race, ethnicity, and identification as special needs were incorporated into data analysis to identify potential trends.
Results: Of 1,219 charts, 661 charts were included for analysis. The average wait for GA was 364.8 days. 171/661 patients (26%) presented to UC during this time with pain being the most common chief complaint (73%) and extraction being the most common treatment (55% of UC encounters). The average time between waitlist placement and UC presentation was 171 days. 153/575 non-SDF patients presented to UC (27%) compared to 18/86 (21%) SDF patients. There was positive correlation between days spent on the GA waitlist and number of UC visits (P =.047).
Conclusions: Though odds of presenting to UC were decreased with SDF application, this was not found to be statistically significant. There was a significant correlation between the amount of time spent on the GA waitlist and the number of urgent care encounters. More data points could provide more significant results.
