The dental sac plays an important role in the formation of all of the following except:

The dental lamina is induced to proliferate into a tooth bud by the:

Normal function of saliva:

One of the following characterize prenatal development It is:

The apposition stage of tooth development begins:

Pure mucous salivary gland is:

The Hertwig epithelial root sheath of disintegrates:

In a developing tooth, if Hertwig’s sheath and the epithelial diaphragm were failed to form, the resulting tooth would exhibit:

Taste Buds are located:

The caries, all are true except:

Appositional stage is confined from:

One of the following Which of induces the dental papilla cells to be differentiated into odontoblasts is:

Odontoblasts start their secretory activity:

Component of mastication are:

Neural crest cells are a temporary group of cells unique to vertebrates that arise from the embryonic ectoderm cell layer, and in turn give rise to A diverse cell lineage including:

The dental sac is:

After fertilization of ovum series of cell division give rise to an egg cell mass called:

The vestibular lamina gives rise to:

All of the following does occur in the active phase of tooth eruption, except:

The dietary carbohydrate most likely involved in etiology of dental caries is:

The embryo’s stomodeum is lined by:

Initiation of caries by Streptococcus mutans is by the production of the:

After ovulation the ovum can be fertilized for about:

Four basic qualities:

Streptococcus mutans is considered to be a principal etiologic agent of caries because it produces acid and it:

The cranial nerve supplies to muscles of mastication is:

The cap stage occurs between the:

The following embryonic structures contribute to the formation of lower lip:

The primary cause of periodontal disease is:

Taste bud is:

One of the following is associated with an erupted tooth:

The occipital somite’s myotomes give rise to:

In patient with reduced salivary flow the carious incidence is:

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

The ICM, inner cell mass, cells have the potential to generate any cell type of the body, after implantation, they are ————– as they differentiate to other cell types with more limited developmental potential. ?

How many types of intra oral tissue?

An undifferentiated cell of a multicellular organism which is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation.?

What is the outcome of repair?

Growth factor responsible for repair and regeneration: KGF, Keratinocyte growth factor?

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

Chromatin immunoprecipitation (ChIP) is a type of immunoprecipitation experimental technique used to investigate the interaction between?

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

Embryonic stem cells were banned for basic research practice because it is an unethical practice. Moreover, it cannot create patient-match specific cell line.?

Mesenchymal stem cells have been confirmed able to differentiated into neuron cell with function?

Transcription can be divided into 3 stages: initiation, elongation, and termination, each regulated by a large number of proteins such as transcription factors?

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.?

Why generation of iPSc is so attractive to scientist worldwide?

Cells responsible for repair and regeneration consist of?

Morphology of mesenchymal stem cells ?

What is the hierarchy of induced pluripotent stem cells?

What is the biggest conflict of using induced pluri-potent stem cells?

Growth factor responsible for repair and regeneration: TGF-b, Transforming growth factor b.?

What are the function of transcription factors?

There are two major factors influence repair and regeneration?

Growth factor responsible for repair and regeneration: VEGF, Vascular endothelial growth factor?

The process of making messenger RNA (mRNA) from a DNA template by RNA polymerase?

Transcription factor sometimes is called sequence-specific DNA-binding factor.?

iPSc were generated by:?

What is Yamanaka’s factors?
