Before restoring a tooth with composite, the area is etched. Accidental contamination occurs with saliva, Therefore
1) the area is re-etched before restoration
2) the area is air-dried using an air spray and continue with restoring
3) wipe the saliva with cotton and continue to restore.
4) add excess composie material and cure it
Etching of tooth surface with 37% phosphoric acid creates microporosities in the enamel and dentin.
After etching the surface energy of the enamel will increase. This will make it very sticky to any kind of contaminants. If salivary contamination will occur, the salivary proteins will precipitate in the microporosities. This will prevent the adequate penetration of the bonding agent, therby reducing the micotag formation. Hence, complete isolation is essential.

The proposed mechanism by which a calcium hydroxide preparation initiates
secondary dentin formation in direct
pulp cappings is by
1) releasing calcium ions.
2) stimulating differentiated ameloblasts to lay down dentin.
3) stimulating fibroblasts to elaborate nuclei of the first order.
4) stimulating undifferentiated cells of the tissue to differentiate into
odontoblasts.
Calcium hydroxide is commonly used in pulp capping procedures due to its ability to promote healing and dentin formation:
- Stimulating undifferentiated cells of the tissue to differentiate into odontoblasts: Calcium hydroxide encourages the differentiation of pulp cells into odontoblast-like cells, which then produce secondary dentin. This is a critical mechanism for pulp healing and dentin regeneration.
- Releasing calcium ions: While calcium ions are released, the primary action is the stimulation of cell differentiation.
- Stimulating ameloblasts: Ameloblasts are involved in enamel formation, not dentin, so this option is incorrect.
- Stimulating fibroblasts: This is not the primary mechanism for secondary dentin formation.

Ipratropium bromide is useful in bronchial asthma because of
1) Anticholinergic effect
2) Vasodilator properties
3) Antiallergic action
4) Stabilization of mast cells
Ipratropium (as ipratropium bromide, trade name Atrovent) is an anticholinergic drug administered by inhalation for the treatment of obstructive lung diseases. It acts by blocking muscarinic receptors in the lung, inhibiting bronchoconstriction and mucus secretion. It is a non-selective muscarinic antagonist, and does not diffuse into the blood, which prevents systemic side effects.
Ipratropium is a derivative of atropine[1] but is a quaternary amine and therefore does not cross the blood-brain barrier
