The document discusses the role of carbohydrates in dental caries (tooth decay). It states that fermentable carbohydrates like glucose, fructose, and sucrose are easily fermented by bacteria like Streptococcus mutans in dental plaque, producing acids that demineralize tooth enamel and lead to cavities. The rate of decay depends on the type of carbohydrate, frequency of consumption, and how long sugars remain stuck to teeth. It also discusses factors like microorganisms, acids, dental plaque, and tooth structure that influence the caries process according to Miller's chemico-parasitic theory.

Histopathology & microbiology of dental caries
The document summarizes the histopathology of dental caries. It describes how dental caries is a microbial disease that causes demineralization of tooth enamel and dentin. It discusses the role of bacteria like Streptococcus mutans in producing acid that dissolves tooth structure. The summary describes the microscopic appearance of carious lesions in enamel and dentin, including the formation of zones of demineralization and bacterial invasion of dentin tubules over time. Advanced caries can ultimately lead to tooth cavitation and pulp involvement if left untreated.
DENTAL CARIES
Dental caries is caused by demineralization of tooth structure due to acid produced by oral bacteria. It is characterized by loss of both inorganic and organic components of the tooth. Dental caries has been defined and classified in various ways based on factors such as the anatomical site, severity, tissue involvement, number of surfaces affected, and chronology. The key etiological factors include the presence of cariogenic bacteria in dental plaque, a susceptible tooth substrate, and a cariogenic diet. Secondary factors like time, the dynamic process of demineralization and remineralization, and saliva also influence the development of dental caries.
the cause of teeth decay
Tooth decay is caused by plaque bacteria in the mouth that feed on sugars and starches, producing acids that destroy tooth enamel. Left untreated, it can lead to cavities, abscesses, and other dental problems. Risk factors include frequent consumption of foods high in sugar like candy, chocolate, soft drinks, and carbohydrates without proper brushing and flossing. Maintaining good oral hygiene through regular brushing and flossing, limiting sugary foods and drinks, avoiding tobacco use, and a balanced diet can help prevent tooth decay.
DENTAL PLAQUE & CARIES
Dental plaque is a filmy deposit on teeth consisting of mucus, bacteria, food and other particles. It can lead to tooth decay, a process where enamel and dentin are demineralized and destroyed, potentially causing cavities. Factors that increase decay risk include foods high in sugar, poor oral hygiene, smoking, dry mouth and Sjogren's Syndrome. Decay happens when acids from plaque dissolve enamel. Dentists can detect decay through examining teeth for soft areas, probing with instruments, and taking dental x-rays to view the extent of cavities.
Dental Caries
Dental caries is caused by an interaction between fermentable carbohydrates, bacteria in dental plaque, and susceptible tooth surfaces over time. Streptococcus mutans and Lactobacillus species in plaque produce acid as they metabolize carbohydrates, lowering the pH and demineralizing enamel. Factors like restoration of teeth, diet, saliva, age, and fluoride exposure influence caries risk. Caries was historically attributed to worms or humors but is now understood as a chemicoparasitic process initiated by acid from plaque bacteria.
Dental Caries ; A Presentation by- MunabbiR

Dental caries
Dental caries is caused by the interaction of four main factors: the tooth, dental plaque, diet, and time. Dental plaque is a soft biofilm containing bacteria like Streptococcus mutans that produce acid from sugars in the diet, causing demineralization of tooth enamel and leading to cavities. Diet plays a key role, as frequent consumption of fermentable carbohydrates like sucrose promotes acid production. Other factors like saliva, fluoride, socioeconomic status, and education can also influence risk. Dental caries is diagnosed visually, tactilely, and radiographically and can be classified based on location, extent, and rate of progression. Prevention focuses on reducing sugar intake, maintaining oral hygiene to

Dental caries
Dental caries is caused by bacteria in the mouth that metabolize carbohydrates, producing acids that demineralize tooth enamel and dentin. It progresses through stages from early subsurface lesions to cavity formation and bacterial invasion. Risk factors include diet, oral hygiene, tooth composition, and saliva. Treatment involves preventing demineralization through fluoride, controlling plaque and bacteria, and restoring teeth through fillings or other methods.
Dental caries 1
Dental caries, also known as cavities, are caused by bacteria in the mouth that feed on sugars and produce acid, which demineralizes tooth enamel over time. The main bacteria involved are Streptococcus mutans and Streptococcus sobrinus. These bacteria live in dental plaque on the teeth. Factors like frequent sugar consumption, poor oral hygiene, and low saliva flow can promote the growth of these cariogenic bacteria and lead to tooth decay. Other contributors include tooth anatomy, acid erosion, and lack of fluoride exposure.
Dental caries , its etiology
Dental caries is caused by an imbalance between demineralization and remineralization of tooth enamel and dentin. It is a bacterial infection resulting from acids produced during bacterial metabolism of dietary carbohydrates. Key factors in the development of caries include the oral bacteria Streptococcus mutans, frequent consumption of fermentable carbohydrates, and conditions like low saliva flow that reduce the buffering capacity of saliva. The caries process involves a dynamic interplay over time between demineralization of enamel during periods of acid production, and remineralization when pH rises. If demineralization exceeds remineralization, it can lead to cavitation and destruction of tooth structure.
Dental caries
Dental caries is caused by an interaction between oral bacteria, fermentable carbohydrates, and tooth surfaces over time. Miller's chemico-parasitic theory is the most widely accepted explanation of the etiology. It states that acids produced by oral bacteria from carbohydrates lead to enamel demineralization and destruction. Clinical presentation varies and includes pit and fissure caries, smooth surface caries, and root caries. Histologically, caries progresses through zones of demineralization and remineralization in both enamel and dentin. Prevention focuses on modifying the oral environment, bacteria, and substrate to reduce acid production and demineralization.
Dental Caries
The document defines dental caries as a disease caused by bacteria in the mouth that ferment dietary carbohydrates, producing acid that demineralizes tooth enamel and destroys tooth structure. The major factors contributing to dental caries are certain bacteria like Streptococcus mutans; dental plaque that allows bacteria to adhere to teeth; saliva, which can increase the cariogenic effect while also helping to clean teeth; and consumption of fermentable carbohydrates like sugars, which feed the bacteria. The microbiology section notes that the main bacteria involved are streptococci and lactobacilli, while other bacteria like actinomyces may also play a role.
Dental caries
Dental caries is the most common microbial disease affecting the tooth. Even through extensive studies over the years, the pathogenesis remains questionable. Hence a fundamental understanding of caries and its theories is essential as data from the past serves as the most vital evidence in the unavoidable quest to figure out the pathogenesis.

Dental caries is an infectious microbial disease of the tooth that results in localized destruction and dissolution of calcified tissues.
Dental caries is one of the most prevalent chronic diseases of people worldwide; individuals are susceptible to this disease throughout their lifetime.
Dental caries
This document discusses dental caries (tooth decay), including its causes, classification, and epidemiology. It defines dental caries as the breakdown of teeth due to bacterial activity. It is most commonly caused by bacteria in dental plaque producing acid when fed fermentable carbohydrates, which demineralizes enamel over time. Dental caries is classified based on location, progression speed, recurrence, extent of damage, and other factors. Globally, it affects around 36% of people and prevalence varies significantly between populations and countries.

This document provides an overview of dental caries, including its:
- History from ancient fossils to modern concepts
- Definitions from various sources
- Etiology and theories about its causes including microbial, chemical, and proteolytic theories
- Classification and factors related to susceptibility in the host like tooth morphology, position, and composition
39.erosion
Erosion is the chemical process of tooth substance loss without bacterial involvement. It occurs when tooth surfaces are exposed to acids from intrinsic sources like gastric reflux or vomiting, or extrinsic sources like acidic foods and beverages. Clinical features include smooth lesions on the front teeth surfaces that cause hypersensitivity. Radiographs may show radiolucent defects in the crown. Management involves diet control, fluoride use, changing brushing habits, and restorations or systemic treatment depending on the cause of erosion.
Biochemistry of dental caries
Dental caries, also known as tooth decay, is one of the most common health problems worldwide. It is caused by bacteria in the mouth that produce acids that dissolve tooth enamel. There are five stages of tooth decay. Cavities start small but can grow larger and deeper if not treated, potentially leading to tooth pain, infection, and loss. Regular dental visits and proper brushing and flossing can help prevent cavities. Treatment options depend on the stage of decay and include options like fillings, root canals, or tooth extractions.
Diet and dental caries /orthodontic courses by Indian dental academy
This document discusses the relationship between diet and dental caries. It provides definitions of key terms like diet, dental caries, and food. It describes dental caries as a multi-factorial disease influenced by host, microflora, substrate/diet, and time. Certain types of fermentable carbohydrates like sucrose are particularly cariogenic due to the way they are metabolized by cariogenic bacteria to produce acid and polysaccharides. Epidemiological, institutional, and animal studies provide evidence that increased sugar consumption is correlated with higher rates of dental caries. Some foods like xylitol, milk, and phosphate have been shown to reduce dental caries.
Diet and dental caries edited
The document discusses the relationship between sugars and dental health. It notes that sugars and fermentable carbohydrates provide substrate for oral bacteria to produce acid, which begins the process of tooth demineralization if not balanced by remineralization. Frequent consumption of sticky, sucrose-containing foods between meals is most cariogenic, while liquid foods and those consumed with meals are less so. The document also discusses factors like food texture and stickiness, saliva flow, and buffers that determine a food's cariogenic potential.

Role of diet and nutrition in dental caries
This document discusses the role of diet and nutrition in dental caries (tooth decay). It states that carbohydrates play a major role in causing dental caries. Added sugars are particularly problematic if good oral hygiene is not maintained. While vitamins D and K can help support dental health, fluoride also plays an important role in preventing decay when found in sources like milk, meat, breads and cereals. The document advises limiting foods high in fat and sugars to reduce risks of dental caries.
Diet and caries
The document discusses sugars and their impact on dental health. It classifies sugars as either intrinsic or extrinsic, with extrinsic sugars like table sugar being more cariogenic since they are more readily available to oral bacteria. Non-milk extrinsic sugars are considered the most damaging. The recommended daily intake of these sugars is no more than 60g. While fresh fruit is low in cariogenicity, fruit juices and dried fruits are more cariogenic due to released sugars. Certain groups are at higher risk of dental caries based on their diets, such as those who consume sugar before bedtime or have medical conditions affecting sugar intake or saliva production. Diet analysis focuses on cariogenic snacks, drinks, and medications
Presentation1
This document discusses the immunological aspects of dental caries. It begins by outlining the innate and adaptive immunity in the oral cavity. Natural immunity to dental caries is discussed, including maternal protection and natural caries immunity in children. Key microbial targets for dental caries vaccines are mutans streptococci, due to their role in acid production and dental plaque formation. Effective targets for vaccines include adhesins, which aid in bacterial adhesion, and glucosyltransferases, which produce glucans important for plaque formation.
Pedia caries prevention
Dental caries is caused by acid-forming bacteria in dental plaque that metabolize fermentable carbohydrates. The process involves alternating periods of demineralization and remineralization of tooth enamel based on the pH level in the mouth. Streptococcus mutans is the primary cariogenic bacteria. Risk factors include frequent sugar consumption, poor oral hygiene, fluoride deficiency, and low saliva flow. Caries can be detected clinically, radiographically, and newer methods involving electrical resistance, light illumination, and digital imaging. Remineralization through fluoride and controlling bacteria and diet can prevent or reverse early caries.

Theories of dental caries.ppt
There are several theories that attempt to explain the process of dental caries:
1) The chemical (acid) theory proposes that acids formed by the fermentation of food particles around the teeth destroy the teeth.
2) The parasitic (septic) theory associates microorganisms with the carious process.
3) The acidogenic theory describes dental decay as a two-stage chemoparasitic process involving decalcification of enamel and subsequent destruction of softened enamel and dentin, supported by the presence of carbohydrates, microorganisms, and dental plaque.
Epidemiology of dental caries
This document provides an overview of dental caries epidemiology. It begins with definitions of epidemiology and dental caries. It then discusses the history of caries in prehistoric man and global and Indian caries scenarios. Several classic epidemiological studies on dental caries are summarized. Theories of caries etiology including Miller's chemico-parasitic theory are explained. Epidemiological factors influencing caries including the host, agents, environment and time are described. Saliva properties and their relationship to caries susceptibility are also summarized.
Diet, health oral health
Dietary counseling provides individualized nutritional care to encourage modified eating habits and can help prevent or treat nutrition-related illnesses affecting the oral cavity. A healthy diet according to the USDA emphasizes fruits, vegetables, whole grains, lean proteins and low-fat dairy while limiting sugar, salt, and saturated fats. Appropriate nutrition plays a major role in oral health by impacting dental caries, erosion, development, and periodontal disease. Maintaining a healthy diet and visiting the dentist twice yearly can help keep teeth and gums healthy.
Pathogenesis of dental caries
This document discusses the pathogenesis of dental caries. It begins by explaining that dental caries is caused by the interaction of sugars, teeth, and microorganisms. It then discusses the roles that various factors play in the disease process, including sugars/carbohydrates, microorganisms like Streptococcus mutans, lactic acid production, dental plaque, and the buffering effects of saliva. The document also explains the cycles of demineralization and remineralization that can occur, and the histological changes seen in carious lesions over time.
Basic concepts and principles of epidemiology
Epidemiology is the study of disease distribution and determinants in populations. Descriptive epidemiology involves describing disease patterns, while analytical epidemiology tests hypotheses about disease determinants. A case-control study compares exposures in individuals with (cases) and without (controls) a disease to identify potential risk factors. It proceeds backwards from effect to cause by first identifying cases and then finding controls to measure past exposures, which are then analyzed using measures like odds ratios.

Epidemiology ppt
Epidemiology is the study of disease patterns in human populations and the factors that influence health. It involves measuring disease frequency, investigating causes, and controlling health problems. The goals of epidemiology are to understand and reduce the burden of disease in society. Key aspects include describing disease distribution, identifying risk factors, and evaluating interventions. The history of epidemiology began with early physicians like Hippocrates and made advances through pioneers such as John Graunt, William Farr, and John Snow, who conducted seminal studies linking disease to environmental factors. Epidemiology now covers a wide range of fields and plays an important role in public health.
sugar-substitutes-pedo
This document discusses different types of sugar substitutes, including nutritive and non-nutritive sweeteners. Non-nutritive sweeteners like aspartame, saccharine, cyclamate, and sucralose are intensely sweet but provide no calories. Nutritive sweeteners provide calories and include sugars like glucose, fructose, lactose, as well as sugar alcohols like sorbitol, mannitol, and xylitol. While some non-nutritive sweeteners have disadvantages like potential cancer risks, nutritive sweeteners and sugar alcohols are less cariogenic than sucrose and may help prevent tooth decay.
Epidemiology of dental caries
This document discusses the epidemiology of dental caries. It begins by defining dental caries and exploring early theories about its etiology. It then examines the epidemiological triad of host, microbes, and environment. Several key studies are summarized that demonstrate the role of diet, particularly sugars, in promoting dental caries. The Vipeholm study showed that increased sugar intake leads to more caries, while the Hopewood House and Turku sugar studies found reductions in caries by limiting sugars and consuming xylitol respectively. Genetic factors and other lifestyle influences on dental caries prevalence are also briefly mentioned.

Plaque, Calculus, and Soft Deposits PowerPoint
This document discusses dental plaque, calculus, and soft deposits. It defines plaque as a sticky mass that contains bacteria and grows on teeth. Left untreated, plaque can lead to tooth decay and periodontal disease. Calculus is mineralized plaque that has hardened onto teeth and requires professional removal. The document outlines the formation and risks of plaque, as well as methods for detecting and removing it and calculus through tools like disclosing agents. Maintaining good oral hygiene through brushing, flossing, and professional cleanings can prevent the buildup of these deposits and diseases.

This document discusses dental caries (tooth decay). It describes caries as a multifactorial, sugar-dependent infectious disease caused by an interaction between bacteria in dental plaque and fermentable carbohydrates. Certain bacteria like Streptococcus mutans are especially adept at producing acid from sugars, which demineralizes tooth enamel over time if remineralization does not match demineralization. Factors that influence the development of caries include diet, oral hygiene, fluoride exposure, tooth structure, and flow of protective saliva. The document provides details on the etiology, pathogenesis, and risk factors involved in the development of dental caries.
2 Dental Caries & Anest.pdf
Dental caries, also known as tooth decay, is caused by certain types of acid-producing bacteria in the mouth that damage tooth structures when fermentable carbohydrates like sugar are present. It can lead to pain, tooth loss, infection, and in severe cases, death. While early signs may include white spots on teeth, untreated caries will form cavities. Risk factors include poor oral hygiene, frequent sugar consumption, dry mouth, and tobacco use. Treatment involves removing decay, restoring teeth, or extracting severely damaged teeth to prevent further destruction and infection. Preventive measures include proper brushing, flossing, limiting sugar intake, dental sealants, and fluoride therapy.
Dental caries
Dental caries is a progressive bacterial disease that causes damage to teeth. It is caused by bacteria in dental plaque that produce acid by fermenting sugars from the diet. This acid causes demineralization of tooth enamel and dentin. If left untreated, it can lead to tooth decay, pain, and potentially serious systemic infections.
Aetiopathology & classification of caries
This document provides information on the etiology and classification of dental caries. It discusses the multifactorial nature of caries, involving bacteria, susceptible tooth surfaces, and diet playing major roles. It describes theories of caries development including Miller's chemoparasitic theory involving acid production by bacteria leading to demineralization. It also discusses host factors like tooth composition, plaque, diet and its effects on bacteria, the role of time and saliva, and systemic and genetic factors in caries development and susceptibility.
Dental caries and periodontal diseases.ppt
1. Dental plaque is a biofilm that develops on teeth and comprises living and dead bacteria and their products embedded in an organic matrix. The microbial composition of plaque varies between individuals and locations in the mouth.
2. Gingivitis is a reversible form of periodontal disease caused by dental plaque. It involves inflammation of the gingiva without loss of attachment to the tooth. The gingiva become red, swollen and bleed easily but are not painful. Early plaque is dominated by streptococci while established lesions contain increased levels of anaerobic bacteria like Porphyromonas and Prevotella.
3. Dental caries is caused by acid-producing plaque bacteria metabolizing ferment
Denatal caries - Tooth decay
Dental caries is caused by acid-producing bacteria in dental plaque that metabolize sugars from the diet. As the bacteria lower the pH, minerals are dissolved from tooth enamel and dentin, leading to cavitation. The primary bacteria involved are mutans streptococci. Risk factors include frequent sugar consumption. Early lesions appear as white spots on smooth surfaces or pits and fissures. Untreated, caries progresses through enamel and into dentin, forming zones of demineralization and bacterial invasion.

Sanisera Fieldschool 2010, session 4: Dental Health, by Ashley Nagel
The document summarizes various aspects of dental health, including that plaque consists of microorganisms and extracellular matrix, dental calculus is mineralized plaque that attaches to tooth surfaces, and dental caries are demineralization of enamel by bacterial waste products. The main factors influencing caries and calculus are oral hygiene and diet, with complex carbohydrates and refined foods associated with greater risks due to longer oral clearance times. Periodontal disease is influenced by plaque, hygiene, and diet, as bacteria from plaque and the mouth trigger an immune response leading to inflammation and potential tooth/bone loss.
Seminar on early_childhood_caries
Early childhood caries (ECC) is a major public health problem affecting children worldwide. It is caused by an interaction of bacteria, fermentable carbohydrates, and susceptible tooth structure. Risk factors include bottle feeding practices, lack of oral hygiene, and socioeconomic status. ECC begins as white spot lesions on maxillary incisors and can progress rapidly without treatment. Prevention involves reducing sugar intake, brushing with fluoride toothpaste, and dental care.
DENTAL CARIES PPT
- Dental caries is caused by acid-producing bacteria in the mouth that consume sugars, producing acids that demineralize tooth enamel and dentin over time.
- W.D. Miller proposed the chemopasitic theory in 1890 which explained that the presence of fermentable carbohydrates serves as nutrients for bacteria like Streptococcus mutans and Lactobacilli to produce organic acids responsible for dental caries.
- Early childhood caries (ECC), also known as baby bottle tooth decay, is characterized by the presence of decay in primary teeth in children under 6 years old, often caused by prolonged bottle or breastfeeding containing sugars.

Dental caries
This document discusses dental caries, including its etiology, clinical characteristics, and histopathology. It describes how caries is caused by an interaction between host factors, such as tooth composition and saliva, and environmental factors like diet and bacteria. It also summarizes the typical progression and appearance of caries in different locations, such as pits and fissures, smooth surfaces, and root surfaces. Caries develops when acids produced by bacteria in dental plaque from sugars in the diet break down tooth minerals over time. The document provides details on the role of various microorganisms involved at different caries stages.
Caries diagnosis handout
This document provides information on dental caries (tooth decay), including definitions, classifications, diagnostic methods, and treatment considerations. It begins with definitions of dental caries and classifications of caries lesions. It then discusses various diagnostic methods and what they can reveal, such as visual examination, probing, radiography, laser fluorescence, and fiber-optic transillumination. Factors considered in diagnosis and treatment decisions are also summarized, including lesion activity, size, and depth. The goal of diagnosis is early detection to allow for preventive and minimally invasive treatment when possible.
Dental Cavity (Caries)
The document discusses dental cavities, including what they are, how they form, risk factors, signs and symptoms, diagnosis, and treatment options. Cavities are holes in teeth caused by tooth decay from bacteria in the mouth interacting with sugars. They start small in the enamel and get deeper over time. Risk factors include diet, saliva flow, and genetics. Cavities are often diagnosed through dental exams and X-rays. Treatment focuses on prevention through diet and hygiene, remineralization of small cavities, and restoration of larger cavities with fillings or other procedures.

The document provides an introduction to dental caries (tooth decay) as a disease. It defines dental caries according to various authors and organizations. Caries results from an imbalance between tooth mineral and biofilm fluid that causes demineralization of enamel and dentin. Key factors that contribute to this imbalance are the host tooth surface, carbohydrates as a substrate for oral bacteria, the oral biofilm, and time. However, not all individuals with teeth and a biofilm who consume carbohydrates will develop caries, as several risk and protective factors can modify the caries process, such as saliva composition and flow, oral hygiene, fluoride exposure, and diet.
Dental caries ppt
Dental caries is caused by bacterial damage to teeth from plaque and acid production when exposed to fermentable carbohydrates like sugar. The major bacteria involved are Streptococcus mutans and lactobacilli, which adhere to teeth and produce acid from sugars, lowering the pH and demineralizing enamel and dentin. If left untreated, caries can spread to the pulp, causing inflammation and pain. Consequences of untreated dental caries include local infections and possible systemic illnesses.

We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.June 2024 Oncology Cartoons By Dr Kanhu Charan Patro
