epidemiology of dental caries

Which of the following does not con-

tribute to the cariogenicity of Strepto-

coccus mutans?

• Production of extra and intracellular polysaccharides

• Production of acids at high ph values

• To utilise salivary glycoproteins

• Ability to colonize on teeth

The major immunoglobulin in saliva is

• Secretory IgA

• IgG

• IgM

• IgM

Which experimental design was not

aimed for salivary immunity of dental

caries?

• Periglandular salivary immunization

• Parenteral immunization

• Salivary gland immunization

• Temporomandihular joint immunization

Which of the following have been seg-

regated as effective molecular target

for dental caries vaccine?

• Adhesins

• Glucosyltransferases

• Glucan binding proteins

• All of the above

Which caries activity test measures

the rapidity of acid formation in a

stimulated saliva sample?

• Lactobacillus colony count

• Reductase test

• Snyder test

• Buffer capacity test

The lactobacillus count test to assess

caries activity was given by

• Hadley

• Albans

• Snyder

• John snow

Yardstick of detection in snyder test is:

• Acid produced

• Ph change

• Colony count

• Enamel dissolution

Name the dye used in salivary reduc-

tase test:

• Basic fuschin

• Erythrosine

• Diazoresorcinol

• Two tone solution

Topical application of fluoride classi-

fies under which level of prevention

for dental caries:

• Services provided by the individual

• Services provided by the community

• Services provided by the dentist

• All of the above

Appropriate use of fluoride prescrip-

tions and fluoride dentifrice renders

which type of prevention in dental

caries?

• Primordial

• Primary

• Secondary

• Tertiary
