Incorporation of peripheral seal in an impression is necessary to obtain 
 1. Stability
 2. Functionally moulded periphery
 3. Harmonious occlusion
 4. Posterior palatel seal

Incorporation of peripheral seal in an impression is necessary to obtain functionally moulded periphery.

A loosely adherent yellowish-white mass of cellular debris and microorganisms
on the teeth is termed

1. oral deposit

2. materia alba

3. dental plaque

4. salivary pellicle

Milky white, soft, and visible to the naked eye, Lacks the organized structure of dental plaquecomposed of Food debris, bacteria, dead tissue cells, leukocytes, and salivary proteins

Which of the following conditions is not considered as premalignant (or) Which of the following has no precancerous potential?
1) Erosive lichen planus, erythroplakia, and Plummer vinson syndrome
2) Syphilitic glossitis, actinic Keratosis and SLE
3) Leukoedema, stomatitis Nictona palati and xeroderma
4) Leukoplakia, erythroplakia and Bowen disease

Xerostomia is seen in all of the patients except (or) Reduction of salivary flow is not seen in 
 1. Parkinsonism
 2. Phenothiazine therapy
 3. Patients receiving radiation therapy
 4. Early diabetic patient

Xerostomia is seen in all of the patients except Parkinsonism.

Which of the following cements bonds to tooth structure, which has an anticariogenic effect, has a degree of translucency and does not irritate the pulp?

1) Polycarboxylate cement

2) Resin cement

3) Silicate Cement

4) Glass ionomer cement

Chelation of carboxyl groups of the polyacids with the calcium in the apatite of enamel and dentin is the main mechanism through which glass ionomer bonds to tooth structure.

Glass ionomers release fluoride which results in the inhibiton of the progression of secondary caries. GIC is relatively biocompatable.
They elicit a greater pulp reaction as compared to ZnoE but generally less compared to zinc phosphate cement.
