Early Childhood Caries
• Defined as the presence of one or more decayed (non-cavitated or cavitated lesions), missing (due to caries) or filled tooth surfaces in any primary tooth in a preschool-age child between birth and 71 months of age.

Severe Early Childhood Caries (S-ECC)
• Children younger than 3 years of age, any sign of smooth-surface caries is indicative of S-ECC
• Ages 3-5, one or more cavitated, missing (due to caries), or filled smooth sur-faces in primary maxillary anterior teeth or a decayed, missing, or filled score of greater than or equal to four (age 3), greater than or equal to five (age 4), or greater than or equal to six (age 5) surfaces also constitutes S-ECC

Early Childhood Caries
• The biology of ECC may be modified by several factors unique to young children, related to the implantation of cariogenic bacteria, immaturity of the host defense systems, as well as behavioral patterns associated with feeding and oral hygiene in early childhood
• A transmissible infectious disease and which is responsive to preventive strategies
![Page 5: Early Childhood Caries](https://reader035.vdocuments.mx/reader035/viewer/2022062409/568150be550346895dbeddbd/html5/thumbnails/5.jpg)
Etiology of ECC • Dental caries is a common chronic infectious
transmisible disease resulting from tooth-adherent specific bacteria, primarily mutans streptococci (MS), that metabolize sugars to produce acid which, over time, demineralizes tooth structure.
Loesche WJ.,Microbiol Rev 1986;50(4):353-80
![Page 6: Early Childhood Caries](https://reader035.vdocuments.mx/reader035/viewer/2022062409/568150be550346895dbeddbd/html5/thumbnails/6.jpg)
Etiology of ECC
• ECC is caused by mutans streptococci that
ferment dietary carbohydrates to produce acid attacks on susceptible teeth over a period of time
• Sugared beverages are readily metabolized by MS and lactobacilli into organic acids that can demineralize enamel and dentin
![Page 7: Early Childhood Caries](https://reader035.vdocuments.mx/reader035/viewer/2022062409/568150be550346895dbeddbd/html5/thumbnails/7.jpg)
Early Childhood Caries
• Common causative agents are mutans streptococci (MS), including Streptococcus mutans, Streptococcus sobrinus, Streptococcus salivarius, Streptococcus mitis, Streptococcus sanguis
• Lactobacilli also participate in the development of caries playing an important role in lesion progression, but not its initiation
• Salivary gland hypofunction
![Page 8: Early Childhood Caries](https://reader035.vdocuments.mx/reader035/viewer/2022062409/568150be550346895dbeddbd/html5/thumbnails/8.jpg)
Etiology of ECC • The major reservoir of MS is the mother, from
whom the child acquires it during a window period of around 2 years of age
• Mothers with dense salivary reservoirs of MS are at high risk of infecting their infants very early in life [Pediatric Dentistry, vol. 28, no. 2, pp. 106–109, 2006.]
• Poor maternal oral hygiene and higher daily frequencies of snacking and sugar exposure increase the likelihood of transmission of the infection from mother to child [Journal of Dental Research, vol. 82, no. 7, pp. 504–508, 2003.]
![Page 9: Early Childhood Caries](https://reader035.vdocuments.mx/reader035/viewer/2022062409/568150be550346895dbeddbd/html5/thumbnails/9.jpg)
ECC
• The time span between MS colonization and caries lesion development is approximately 13–16 months
• Prenatal and perinatal malnutrition/under nutrition lead to hypoplasia.
• A consistent association has been reported between enamel hypoplasia and ECC
![Page 10: Early Childhood Caries](https://reader035.vdocuments.mx/reader035/viewer/2022062409/568150be550346895dbeddbd/html5/thumbnails/10.jpg)
Cesarean Section vs Vaginal Birth
• Infants delivered by CS acquire S. mutans earlier than vaginally delivered infants
• Vaginal delivery may expose newborns to early protection against S. mutans colonization by exposure to numerous bacteria earlier and with great intensity, affecting the pattern of microbial acquisition
• CS infants have an atypical microbial environment that may increase susceptibility to subsequent early S. mutans colonization
![Page 11: Early Childhood Caries](https://reader035.vdocuments.mx/reader035/viewer/2022062409/568150be550346895dbeddbd/html5/thumbnails/11.jpg)
Cows Milk vs Breast milk
• Cow milk is essentially noncariogenic because of its mineral content and low level of lactose
• Human milk promoted the development of smooth-surface caries and was significantly more cariogenic than cow milk*
• Breast feeding and its duration were independently associated with an increased risk for ECC*
*Canadian Journal of Public Health, vol. 91, no. 6, pp. 411–417, 2000.

Caries Process• The presence of a fermentable carbohydrate
(e.g., sucrose, glucose, fructose, cooked starch) and biofilms on the teeth
• Support the metabolism of acidogenic microorganisms, leading to acidic substances
• Hydrogen ions dissolve the carbonated hydroxyapatite crystal lattice of enamel, cementum, and dentin
• Continued demineralization results in cavitation of the tooth enamel surface
![Page 13: Early Childhood Caries](https://reader035.vdocuments.mx/reader035/viewer/2022062409/568150be550346895dbeddbd/html5/thumbnails/13.jpg)
ECC and Other Health Issues
• Infants with ECC grow at a slower pace • Young children with ECC may be severely
underweight because of associated pain and their disinclination to eat
• ECC may also be associated with iron deficiency

Standard Dental Treatments• Prevention (People remain susceptible to the
disease throughout their lives)• Fluoride (2x/d brushing fluoridated paste with
eruption of 1st tooth)• Topical Antimicrobial Therapy• Casein Phosphopeptide-Amorphous Calcium
Phosphate (CPP-ACP)• Dental Fluorosis• Restoration or the surgical removal (40%
reoccurrence in 1st year)
![Page 16: Early Childhood Caries](https://reader035.vdocuments.mx/reader035/viewer/2022062409/568150be550346895dbeddbd/html5/thumbnails/16.jpg)
Topical Antimicrobial Therapy
• Povidone-iodine has suppressive effects on the oral colonization of MS and prevented dental caries
• Povidone-iodine has strong bactericidal/virucidal effects and demolishes normal flora in the pharynx and the oral cavity, which interfere with pathogenic viral invasion
• Therefore, povidone-iodine should not be routinely used

Topical Antimicrobial Therapy
• Topical 0.12% chlorhexidine gluconate could significantly reduce MS levels
• Chlorhexidine therapy was much less effective
at reducing the levels of lactobacilli in the human mouth
![Page 18: Early Childhood Caries](https://reader035.vdocuments.mx/reader035/viewer/2022062409/568150be550346895dbeddbd/html5/thumbnails/18.jpg)
Casein Phosphopeptide-Amorphous Calcium Phosphate (CPP-ACP)
• Shown to reduce demineralization and promote remineralization of carious lesions
• CPP-stabilized amorphous calcium fluoride phosphate had a greater remineralizing effect than fluoride or CPP-ACP individually
• CPP-ACP used as a self-applied topical coating, after the teeth have been brushed with a fluoridated toothpaste

Fluoride supplements recommended for preventing caries
• Evidence of effectiveness of supplements in caries prevention in primary teeth is weak
• For permanent teeth daily use of supplements prevented dental caries
• Supplements during the first 6 years of life, and especially during the first 3 years, is associated with an increase in fluorosis
• Fluoride supplement should not be given to infants

AAPD Preventive Measures
Decrease transmission of cariogenic bacteria• Reduce parent/sibling MS levels • Minimizing saliva-sharing activities (eg,
sharing utensils)• Implement oral hygiene measures no later
than the first primary tooth eruption• Brush BID (age-related dose of fluoride
toothpaste)
![Page 21: Early Childhood Caries](https://reader035.vdocuments.mx/reader035/viewer/2022062409/568150be550346895dbeddbd/html5/thumbnails/21.jpg)
AAPD Preventive Measures
• Establishing a dental care within six months of eruption of the first tooth and no later than 12 months of age – conduct a caries risk assessment – provide parental education
![Page 22: Early Childhood Caries](https://reader035.vdocuments.mx/reader035/viewer/2022062409/568150be550346895dbeddbd/html5/thumbnails/22.jpg)
AAPD Preventive Measures
• Avoiding high frequency consumption of liquids and/or solid foods containing sugar.– sugar-containing beverages (eg, juices, soft drinks,
sweetened tea, milk with sugar added) in a baby bottle or no-spill training cup
– infants should not be put to sleep with a bottle filled with milk or liquids containing sugars
![Page 23: Early Childhood Caries](https://reader035.vdocuments.mx/reader035/viewer/2022062409/568150be550346895dbeddbd/html5/thumbnails/23.jpg)
AAPD Preventive Measures
• Avoid ad libitum breast-feeding after the first primary tooth begins to erupt and other dietary carbohydrates are introduced
• Encouraged infants to drink from a cup as they approach their first birthday
• Infants should be weaned from the bottle between 12 to 18 months of age.

Probiotic Streptococcus salivarius strain M18
• Produces bacteriocins targeting the cariogenic species Streptococcus mutans, as well as the enzymes dextranase and urease
• RDBPC study of 100 dental caries-active children for 3 months
• Plaque scores were significantly lower for children in the M18-treated group
• Concluded that S. salivarius M18 can provide oral health benefits when taken regularly

Lactobacillus reuteri
• Evaluate the effect on the oral health of 9 year olds after:
• Daily oral supplementation with the probiotic Lactobacillus reuteri, strain ATCC 55730, to mothers during the last month of gestation and to children through the first year of life
• A single-blind, placebo-controlled, multicenter trial of 113 children: 60 in the probiotic and 53 in the placebo group

Lactobacillus reuteri• Saliva and plaque similar in both groups for
mutans streptococci (MS) and lactobacilli (LB) in saliva and plaque as well as salivary secretory IgA (SIgA)
• Within the limitation of this study it seems that daily supplementation with L. reuteri from birth and during the first year of life is associated with reduced caries prevalence and gingivitis score in the primary dentition at 9 years of age.
