About This Presentation

Description : Check out this medical PowerPoint presentation titled "Caries”.

This medical PowerPoint presentation is about caries, a term used to describe tooth decay, which is a common dental problem caused by the demineralization of the tooth enamel and dentin. It is primarily caused by the bacteria in the mouth, which convert the carbohydrates and sugars present in the food we eat into acid. This acid, along with the bacteria and food particles, forms a sticky film on the teeth called plaque.

When plaque is not removed by regular brushing and flossing, the acid produced by the bacteria in the plaque gradually erodes the enamel and dentin, causing cavities or holes in the teeth. If left untreated, caries can progress deeper into the tooth, affecting the nerves and blood vessels, and eventually leading to tooth loss.

Preventing caries involves maintaining good oral hygiene, such as brushing twice a day, flossing daily, and using fluoride toothpaste to strengthen the tooth enamel. Additionally, reducing the frequency of sugary and acidic foods and drinks, and visiting the dentist regularly for cleanings and checkups can also help prevent caries.

2 www.aap.org/oralhealth/pact Introduction Caries is an infectious transmissible disease resulting from tooth adherent bacteria that metabolize sugars to produce acid which ultimately demineralize tooth structure and, if left untreated, can progress to a cavity. Dental caries is the most common chronic disease of childhood and disproportionately affects poor and minority populations. Early Childhood Caries, or ECC, is the presence of 1 or more decayed, missing (due to caries), or filled tooth surfaces in any primary tooth in a child under the age of 6. used with permission from Ian Van Dinther

4 www.aap.org/oralhealth/pact Etiology and Pathophysiology There are 3 requirements for the formation of dental caries: 1. Cariogenic bacteria 2. Sugar 3. Teeth Because dental caries has a microbial etiology, caries cannot form in the absence of cariogenic bacteria, regardless of sugar intake. Used with permission from Miller Medical Illustration & Design
Slide 5-

5 www.aap.org/oralhealth/pact Etiology and Pathophysiology Bacteria adhere to the tooth surface in a biofilm called dental plaque. When carbohydrates are consumed, they are metabolized by bacteria and produce acid as a byproduct. The acid causes demineralization of the tooth enamel over time. created by AAP Oral Health Staff Caries
Slide 6-

6 www.aap.org/oralhealth/pact Etiology and Pathophysiology, continued The following factors contribute to demineralization: High cariogenic bacterial load Frequent feedings Poor oral hygiene Decreased saliva production
Slide 7-

7 www.aap.org/oralhealth/pact Etiology and Pathophysiology, continued These factors aid in the remineralization process: Saliva Good oral hygiene A non-cariogenic diet However, it is possible to reverse the demineralization process before cavitation occurs.

Slide 8-

8 www.aap.org/oralhealth/pact Bacteria The primary bacterial species involved in the pathogenesis of caries is Streptococcus mutans, but many other bacteria have also been implicated, including S sobrinus, Actinomyces sp, and Lactobacillus sp. High levels of cariogenic bacteria are indicative of active caries process and are associated with increased risk of new caries development Used with permission from Rocio B. Quinonez, DMD, MS, MPH; Associate Professor Department of Pediatric Dentistry, School of Dentistry University of North Carolina
Slide 9-

9 www.aap.org/oralhealth/pact Bacteria, continued Plaque is composed of salivary proteins that adhere to teeth, as well as bacteria and their byproducts. Plaque harbors the bacteria that initiate the demineralization process. Adequate plaque control can reduce the likelihood of developing dental caries. Used with permission from Sunnah Kim
Slide 10-

10 www.aap.org/oralhealth/pact S Mutans S. mutans is concentrated in the pits and fissures of teeth, so the grooved surfaces of the molars are the most common site for caries lesions.

Slide 11-

11 www.aap.org/oralhealth/pact S. Mutans, continued The virulence of S. mutans varies by strain. The type of S. mutans cannot be modified, but the amount of bacteria can be altered. These methods can be used to decrease bacteria and minimize caries: Brushing with fluoride toothpaste Professional dental cleanings Exposure to topical fluoride Chlorhexidine mouthrinses and Xylitol use Flossing Used with permission from Valerie Abbott
Slide 12-

12 www.aap.org/oralhealth/pact S Mutans, continued S mutans is transmitted from the primary caregiver to infant by saliva. Transmission rates increase when parents: Share utensils or toothbrushes. Taste food or drink before serving it. “Clean” a dropped pacifier with saliva. Allow a child to place fingers into an adult's mouth. Used with permission from Jamie Zaleski
Slide 13-

13 www.aap.org/oralhealth/pact Sugar The metabolism of carbohydrates by oral bacteria creates acid that demineralizes enamel. The risk of demineralization and caries development is directly related to the frequency with which the teeth are exposed to sugar. Used with permission from Content Visionary
Slide 14-

14 www.aap.org/oralhealth/pact Sugar, continued Caries development is positively associated with the following activities: Frequent or prolonged contact of the teeth with sugary substances. Consumption of sticky foods. Dipping a pacifier in sweeteners like honey or corn syrup. Regular use of medications that contain sucrose, including some multi-vitamins. Used with permission from ANZ Photography
Slide 15-

15 www.aap.org/oralhealth/pact Sugar, continued Caries risk is reduced when: Teeth are brushed immediately after eating to remove sticky foods. Fresh fruit, vegetables, and whole grain snacks are chosen instead of candy or juice. Used with permission from Melinda Clark, MD, Associate Professor of Pediatrics, Albany Medical Center
Slide 16-

16 www.aap.org/oralhealth/pact Enamel Enamel is a physical barrier to bacterial invasion of the tooth. Acid produced by bacteria on the teeth demineralizes the enamel. When the enamel is weakened or less able to remineralize, the risk for caries is increased. The health and strength of the enamel can be modified by changing health behaviors.

Slide 17-

17 www.aap.org/oralhealth/pact Dental Sealants Outside the Early Childhood Caries (ECC) age range, the majority of caries develop on grooved surfaces of teeth—the pits and fissures of the molars. This is why dental sealants are an effective method of caries prevention. Used with permission from David A. Clark, MD; Chairman and Professor of Pediatrics at Albany Medical Center
Slide 18-

18 www.aap.org/oralhealth/pact Saliva Saliva has several important properties that help to protect against the majority of carious lesions: Saliva buffers acid. Saliva is bacteriostatic. Saliva aids in remineralizing the teeth.
Slide 19-

19 www.aap.org/oralhealth/pact Saliva, continued Decreased saliva production promotes development of caries. Possible causes of limited saliva production include: Systemic diseases Salivary gland damage from surgery or radiation therapy Medication effects
Slide 20-

20 www.aap.org/oralhealth/pact Saliva, continued Medications are the most common cause of decreased saliva production in children. Pediatricians need to be aware of this risk and choose medications carefully. Used with permission from Joe Martinez

21 www.aap.org/oralhealth/pact Early Childhood Caries (ECC) ECC is defined as the presence of 1 or more decayed, missing (due to caries), or filled tooth surfaces in any primary tooth in a child under the age of 6. ECC typically results in severe tooth morbidity and extensive restorative treatment needs. Used with permission from Noel Childers, DDS, MS, PhD; Department of Pediatric Dentistry, University of Alabama at Birmingham
Slide 22-

22 www.aap.org/oralhealth/pact Early Childhood Caries, continued ECC affects 24.7% of children in the United States. ECC is concentrated among poor and minority children, with 80% of total tooth decay occurring in 25% of the nation's children. Used with permission from iStock
Slide 23-

23 www.aap.org/oralhealth/pact Pattern of primary tooth eruption The typical pattern of primary tooth eruption is: 1. Lower central incisors 2. Upper central incisors 3. Lateral incisors 4. First molars 5. Canines (cuspids) 6. Second molars Used with permission from the American Dental Association
Slide 24-

24 www.aap.org/oralhealth/pact Affected Teeth ECC tends to affect the upper (maxillary) incisors first because they erupt earliest and are less protected by saliva. The primary molars are affected next because of their grooved surfaces. Plaque stagnates in the molar’s pits and fissures, which are difficult areas to clean with a toothbrush. Used with permission from Rocio B. Quinonez, DMD, MS, MPH; Associate Professor Department of Pediatric Dentistry, School of Dentistry University of North Carolina
Slide 25-

25 www.aap.org/oralhealth/pact Affected Teeth, continued The canines tend to be spared because they are smooth teeth that erupt later. The lower teeth are better protected by saliva and the tongue. Used with permission from Martha Ann Keels, DDS, PhD; Division Head of Duke Pediatric Dentistry, Duke Children's Hospital
Slide 26-

26 www.aap.org/oralhealth/pact Diagnosis and Stages The stages of ECC are as follows: 1. Plaque: This biofilm contains cariogenic bacteria. 2. Incipient lesions or white spots: Usually begin along the gum line, which is the most important place to examine for ECC. With intervention at this stage, the caries process is entirely reversible. 3. Enamel caries: A defect in the enamel surface is visible. 4. Dentine caries: ECC has extended into the dentine layer, where the nerve and pain fibers are located. 5. Pulpitis: The caries lesion has progressed so that it now affects the pulp.
Slide 27-

27 www.aap.org/oralhealth/pact Impact and Effects on Health ECC increases the risk of caries lesions developing in permanent teeth. Other health effects include: Pain Difficulty chewing, which may lead to poor weight gain Difficulty speaking Oral infections Loss of sleep, difficulty concentrating, and interrupted learning Destruction and loss of teeth Damage to permanent teeth
Slide 28-

28 www.aap.org/oralhealth/pact Impact and Effects on Health, continued ECC results in increased office, dental, and ER visits. These costs far exceed those of preventive dental care. It is 10 times more expensive to provide inpatient care for caries-related symptoms than to provide that same patient the recommended periodic preventive care.
