Sampling is a procedure used to make inferences about a larger population by studying a representative subset of it. There are two main types of sampling: probability sampling, where units have a known, non-zero chance of being selected; and non-probability sampling, where units are selected through convenience. Some common sampling methods include simple random sampling, stratified random sampling, cluster sampling, and multistage sampling. The goal is to select a sample that efficiently and cost-effectively represents the population while addressing requirements like representativeness, measurability, and feasibility.
Remineralization is defined as the process whereby calcium and phosphate ions are supplied from an external source to the tooth thereby, causing ion deposition into crystal voids in demineralized enamel, thus producing net mineral gain.
Remineralization Agents - Biomimetic approaches to stabilization of bioavailable calcium, phosphate, and fluoride ions and the localization of these ions to non-cavitated caries lesions for controlled remineralization.
Fermentable carbohydrates provide plaque bacteria with substrate for acid production.
This causes a rapid drop in plaque pH and when pH becomes less than 5.5, hydroxyapatite in enamel breaks down and calcium and phosphate ions diffuse out from the enamel.
5.5 is the “critical pH”, the point where equilibrium exists. There is no mineral dissolution and no mineral precipitation.
The plaque remains acidic for about 30-60 minutes after which normal pH is restored gradually.
The calcium and phosphate ions re-enter enamel when normal pH is restored and thus remineralization occurs.

The term probiotics is a relatievly new word meaning “for life” and is currently used to name bacteria associated with beneficial effects for humans and animals. The development of resistance to range of antibiotics by some important pathogen has raised a possibility of return to pre antibiotic dark ages. So there was need of new treatment paradigm to be introduced to treat periodontal diseases. This need was fulfilled by the introduction of probiotics. Probiotics are counterparts of antibiotics thus are free from concerns for developing resistance, further they are body’s own resident flora hence are most easily adapted to host. The buzz about probiotics has become a roar but despite great promises, probiotics work is limited to gut. Periodontal works are sparse and need validation by large randomized trials. It can be said probiotics are still in “infancy” in terms of periodontal health benefits, but surely have opened door for a new paradigm of treating disease on a nano molecular mode. Novel species are likely to be added in the future as research data
accumulate. In-depth understanding of the intrinsic microbial ecological control of commensal microbiota may introduce new putative species to this discussion.

definitive.
• Every individual tends to have a relatively stable flora.
• Negative modification is done by Antibiotics.
• Positive modification is done by Probiotics.
4. Introduction
• Probiotics are living microorganisms that are
consumed in order to obtain a beneficial effect
regardless of their intrinsic nutritional value.
5. Introduction
• According to the World Health Organization (WHO),
probiotics are “live microorganisms which, when
administered in adequate amounts, confer a benefit to the
health of the host”.
6. Introduction
• Probiotics can improve the condition of the patient in
disorders such as diarrhea, gastroenteritis, inflammatory
bowel disease (Crohn’s disease and ulcerative colitis),
cancer, inadequate lactase digestion, pediatric allergy,
hyperlipidemia, liver disease, and infection with
Helicobacter pylori infections.
9. History
• In 1990’s at the start of 20th
century, Russian Nobel Prize
winner and Father of modern
Immunology, Elie Metchnikoof,
a scientist at the pasture
institute was the first to
conceptualize “ PROBIOTICS”
10. History
Elie Metchnikoff in his book “ prolongation of life”
(1907) proposed a diet containing milk fermented by
Lactobacilli, which produce large amounts of lactic acid
that could increase the life span of Humans.
In ancient Indian society, it became common place and
still is to enjoy a before dinner yogurt drink called a lassi.
These Indian tradition were based on the principle of
using sour milk as a probiotic delivery system to the
body.

15. What Lactobacillus actually does?
Lactobacillus species
• Enhance Innate and Acquired Immunity.
• Inhibition of pro inflammatory mediators.
• Production of enzymes to digest and
metabolize proteins and carbohydrates.
• Synthesis of Vitamin. B and Vitamin. K and
facilitates breakdown of bile salts.
16. What Bifidobacterium actually does?
Lactobacillus species
• Metabolization of lactose, generate lactic ions
from lactic acid and synthesize vitamins.
• Ferment indigestible carbohydrates and
produce beneficial short chain fatty acids.
17. What Other species actually does?
Lactobacillus species
• Streptococcus thermophilus and lactobacillus
bulgaricus metabolize lactose, improve lactose
tolerance and antimicrobial activity.
18. Selection criteria for probiotics
Lactobacillus species
• Adhesion and Colonization in the human body.
• Enhancement of the specific and non-specific immune
response of the host.
• Production of Antimicrobial substances and competition with
pathogens for binding sites.
• Survival and resistance to human defense mechanism.
• Should considered as the safe microorganism.
23. Competitive Exclusion
Lactobacillus species
In a report addressing the total exclusion of Salmonella
typhimurium from maggots of blowflies published in 1969,
Greenberg first used the ‘competitive exclusion’ term for the
scenario in which one species of bacteria more vigorously
competes for receptor sites in the intestinal tract than another
species.
24. Role of Probiotics and Oral Cavity
Lactobacillus species
In periodontal infection and Halitosis
• Probiotics decrease the pH of oral cavity so that they prevent
the biofilm formation as most of bacteria can not survive in
the low Ph.
• They produce antioxidants so they prevent biofilm formation
by neutralizing the free electrons that are needed for the
mineral formation and reduces bad Oduor from oral cavity.

26. Role of Probiotics and Oral Cavity
In Dental Caries
• Streptococcus mutans is the main causative organism in caries development
due to its ability to produce highly branched, water-insoluble glucan,
mutan.
• The main characteristics of virulence Streptococcus mutans are their
acidogenicity, ability to survival in acidic environments, the ability of
biofilm formation and adherence to the tooth.

DENTAL CARIES Guident Journal Feb2021, Vol. 14 Issue 3, p37-40. 4p.
27. Strains of Lactobacillus rhamnosus, L. casei, L. reuteri and
Bifidobacterium spp. have all demonstrated the potential to alter
colonization of cariogenic bacteria and thus prevent dental caries.
Nase et al and Wu et al (2014-follow-up to six months) have studied
the effect of the probiotic Lactobacillus rhamnosus GG on the risk
of tooth decay and have demonstrated a reduction in caries and
reduced levels of Streptococcus mutans in patients taking the
probiotics of Lactobacillus group.

28. Role of Probiotics and Oral Cavity
In Oral Candidiasis case
Candida species constitutes a part of oral flora in approximately
50% of healthy subjects but are able to cause clinically apparent
lesion if the immune defenses are breached either on the local level
or systemic level.
One study has shown that the subjects who consumed cheese
containing the probiotic L. Rhamnosus GG exhibited reduction in
the prevalence of oral candidiasis.
29. Role of Probiotics and Oral Cavity
In Voice Prosthesis
There is no research regarding relationship between dental
restorative materials and probiotics. However , in Larynx the
second barrier after oropharynx, probiotics strongly reduce the
pathogenic bacteria and biofilms.
30. Role of Probiotics and Oral Cavity
In Orthodontic Treatment
Orthodontic brackets and wire create the environment for the
cariogenic bacteria to grow. Also it causes white spot lesions after
removal of brackets.
Fruit yogurt with Bifidobacterium sub species Lactis is helpful in
the reduction of salivary mutans streptococcus in orthodontic
patients with fixed ortho appliances.
31. Role of Probiotics and Oral Cavity
In Oral Cancer
Probiotics are known to interfere at various stages of the
cancer process by interfering with Chromosomal and DNA
damage.
However , further study is required to develop specific
regulations on their consumption.
32. Probiotics status in India
Lactobacillus species
Indian probiotic market was valued at $2
million as per 2010 estimates. According
to figures released by US-based research
firm, Frost and Sullivan, in August 2012,
probiotic products in India generated
revenue of US $522.8 million in 2018

probiotic nutritional supplements in India. Afri J
Busi Manag 2011; 5: 5418-23.
The latest addition to the list of probiotics
in India is ViBact (genetically modified
Bacillus mesentricus), which acts as an
alternate to B-complex capsules. Daily
intake of 1.5-2 dl per day is recommended
dose.

33. Probiotics status in India
Lactobacillus species
The Indian market is big, but difficult to
reach since cold storage and cold
distribution chain are underdeveloped in
India, especially in the rural areas.
Realizing these drawbacks, YAKULT has
taken an initiative in this direction, and has
already announced to target tier II cities in
their next phase. The strongest sale of
Yakult is recorded from Delhi/ NCR.

34. Future Aspects
Lactobacillus species
Probiotics are already gained access in the western countries
very fast. Various processing advances, such as
microencapsulation and bacterial coating and addition of
prebiotic compounds used as growth factors for probiotic
organisms, will provide a means to optimize the delivery and
survival of strains at the site of action.
However, all the products effective in oral health care are
required to be administered daily, so a possible way of
administration could be incorporate probiotics in toothpaste,
mouthwash, chewing gums, sugar-less candy for kids etc.

35. Conclusion
Lactobacillus species
Probiotic is the natural way to maintain overall health and also
protect the oral cavity from the various dental diseases. Dairy
products and yogurt containing probiotic strains of bacteria are
useful in the prevention of caries in early childhood.
36. Conclusion
Lactobacillus species
During childhood, the gastrointestinal flora is not established and
administration of probiotics at that time gives positive life-long
health. Therefore, a pediatric dentist plays vital role in
maintaining and installing positive life-long health through
probiotics.
