This study will be conducted to:

Evaluate clinically and radiographically apexogenesis in immature permanent molars using:

1. Calcium Hydroxide.
2. MTA.
3. Laser.
4. Laser combined with MTA.

Calcium Hydroxide has been the most commonly utilized pulpotomy agent for vital pulp therapy. It is the earliest medicament employed in pulpotomy that possesses the ability to stimulate tertiary dentinogenesis. This is attributed to its high alkalinity after mixing with water. Calcium hydroxide has a high pH, and its dental use relates chiefly to its ability to stimulate mineralization and also to its antibacterial property.

Biocompatibility and sealing ability are the most important properties, which account for optimal healing response in vital pulp therapy. Unlike conventional materials, MTA has low solubility and maintains its physical integrity after placement. It has several desirable characteristics in terms of biocompatibility, bioactivity, hydrophilicity, radiopacity, sealing ability and low solubility.

Diode laser in a young permanent tooth with traumatically exposed pulp has proved to be an effective technique for Pulpotomy in an immature tooth. Therefore, the use of soft-tissue diode lasers can influence the treatment outcome and should be seen as a predicable tool for vital pulp therapy.
