Miller put forth the acidogenic theory of dental caries in the year:

By the 6th week of tooth development, the oral epithelium is:

Concerning teratogens and their effect on fetal development:

After ovulation the ovum can be fertilized for about:

The little bumps can see on someone’s tongue are:

The pH at which initiation of caries begins is:

The papillae that is projections on the tongue called:

All of the following is a function of dental sac except:

Concrescence usually occurs with:

One of the following causes the discolorations of teeth is:

The lateral spread of dental caries is facilitated mostly by the:

The following Which contain blood vessels is:

Third stage of deglutition is:

All of the muscles mastication is involved in closing the mandible except:

The epithelial component of the tooth germ is known as:

All of the following are involved in the formation of a tooth except:

Median rhomboid glossitis is:

The following is component of the enamel organ except:

The bud stage of tooth development occurs at:

Widely accepted theory of dental caries is:

The vestibular lamina gives rise to:

Turbid dentin in carious tooth is all except:

The three major salivary glands are:

The primary cause of periodontal disease is:

Which minor salivary glands are purely serous:

During tooth eruption, the permanent successors of the primary teeth move occlusal and:

All the statement below is true about the classification of taste, except:

The apposition stage of tooth development begins:

Calcified tissues of the tooth are derived from:

The enamel organ:

Another term for the deglutition of food is:

First stage of deglutition is:

The 3 stages of Deglutition are:

The malleus of inner ear originates from:

Taste buds contain:

The palate is derived from three primordia:

The mesenchymal cells lying adjacent to the inner enamel epithelium:

The process by which information from a gene is used in the synthesis of a functional gene product such as a protein?

Growth factors and their receptors can be grouped into ‘superfamilies,’ based upon shared features of ?

Growth factor responsible for repair and regeneration: FGF, fibroblast growth factor.?

ES will support clinical research on the differentiation and function of human tissues and provide material for testing that may improve the safety and efficacy of human drugs ?

What do Growth Factors Do?

Controlling the rate of gene transcription for example by helping or hindering RNA polymerase binding to DNA?

Growth factor responsible for repair and regeneration: PDGF, Platelet derived growth factor?

Transcription factors is a protein that control the rate of transcription of genetic information from?

All four factors are absolutely necessary. In particular, the gene c-Myc is known to promote tumor growth in some cases, which would not affect iPSC usefulness in transplantation therapies. ?

How many types of intra oral tissue?

Embryonic stem cells are derived from embryos at a developmental stage before the time that implantation would normally occur in the uterus. Normally, it takes about 10 days.?

Repression, or suppression – decrease the rate of gene transcription?

Growth factor is sometimes used interchangeably among scientists with the term cytokine.?

What are the function of transcription factors?

Four transcription factors (Oct4, Sox2, Klf4, and c-Myc) sometimes is called Yamanaka’s factors.?

What is the hierarchy of mesenchymal stem cells?

iPSc were generated by:?

The first differentiation event in humans occurs at approximately —— days of development, when an outer layer of cells committed to becoming part of the placenta (the trophectoderm) separates from the inner cell mass (ICM). ?
