 Etching of tooth surface with 37% phosphoric acid creates microporosities in the enamel and dentin. This is the main method of adhesion of composite resin to tooth surface.
 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 treatment for Hirschsprung disease involves surgically removing the aganglionic segment of the colon and joining the normal colon to the rectum. This effectively restores the normal flow of intestinal contents and resolves the functional obstruction caused by the lack of coordinated peristaltic contractions.

The success of a root canal filling is primarily assessed through clinical observation, which includes monitoring for signs of pain, swelling, and infection. While radiographs and the size of the gutta-percha cone used can provide additional information, the ultimate determinant of success is the patient's symptom resolution and the absence of pathology.
