Indian Dentists Act was formulated in:
# Indian Dentists Act was formulated in:
A. 1942
B. 1947
C. 1948
D. 1949
The correct answer is C. 1948.
Dentist act of India was introduced on 29th March 1948.
Which is NOT a requirement for a local anesthetic drug?
# Which is NOT a requirement for a local anesthetic drug?
A. Lipid solubility.
B. Water solubility.
C. Precipitate in interstitial fluid.
D. Depression of nerve conduction.
The correct answer is C. Precipitate in interstitial fluid.
Local anesthetics must be lipid soluble in order for the drug to cross various barriers in the tissue. Local anesthetics must be water soluble to prevent the drug from precipitating when exposed to interstitial fluids. Local anesthetics must NOT precipitate in interstitial fluid because then they would be ineffective as anesthetics. A local anesthetic’s intended purpose is to block pain; therefore, it must depress nerve conduction.
Components of Acquired Enamel Pellicle
# Which of the following is a component that is not present in the acquired enamel pellicle?
A. Glucan.
B. Proline-rich peptides.
C. Glucosyltransferases.
D. Enolase.
The correct answer is D. Enolase.
Bacterial components such as glucosyltransferases and glucan can be detected in pellicle. Proline-rich peptides can be found in the acquired enamel pellicle. Bacterial components such as glucosyltransferases and glucan can be detected in pellicle. Enolase is an intracellular enzyme found in oral bacteria, but is not a major component of the acquired pellicle.
Etching time is more in primary teeth than permanent teeth due to:
# Etching time is more in primary teeth than permanent teeth due to:
A. Irregular placed enamel rods
B. Aprismatic enamel
C. More inorganic matrix
D. More amount of water
The correct answer is B. Aprismatic enamel.
Deciduous teeth have an outer layer of aprismatic or prismless enamel. They require a longer etching time. Earlier it was advocated 120s, but now reduced to 60 s and more recently to 30s for bonding of pit and fissure sealants and orthodontic brackets. A significant research in this field made it clear that very long etching periods did not improve the bond strengths of the currently available adhesives.
What is Geristore in Dentistry?
# What is Geristore in Dentistry?
A. Rapid setting resin ionomer, has the capacity to bond with the tooth
B. ZOE based sealer
C. Obturating material specifically for deciduous tooth
D. Is a bioceramic
The correct answer is A. Rapid setting resin ionomer, has the capacity to bond with the tooth
Geristore:
• Geristore is a dual-cure, self-adhesive, resin glass ionomer formula that contains fluoride. It is a rapid setting resin ionomer (making it very suitable for repairing perforations when compared to MTA)
• It is hydrophilic, so it will bond in the presence of moisture and blood.
• It has low coefficient of thermal expansion and low polymerization shrinkage.
• It's often recommended when the periodontium is extensively involved. It is biocompatible for soft tissue and teeth - Studies show gingival cell re-attachment to the material, making it excellent for sub-gingival procedures.
Applications:
• Subgingival restorations for root perforation and resorptive lesions.
• Retrograde filling material
• Root caries lesions
• Liner in direct pulp capping
• In class 5, and conservative class 1 & class 2 restorations
Teeth that are least affected by periodontal disease are:
# Teeth that are least affected by periodontal disease are:
A. Lower first molars and upper anteriors
B. Lower premolars and upper canines
C. Lower first molars and upper incisors and premolars
D. Lower centrals, laterals and upper molars
Teeth least affected by periodontitis are upper canine and lower second premolar. Most affected are lower molars. The teeth that are moderately affected by periodontal disease are all the upper molars; the upper centrals. laterals, and premolars; and the lower canines.
