A new Endodontic Cement (NEC) is being compared with mineral trioxide aggregate in pulpotomy of primary molars.

Forty patient are selected randomly. Each patient has at least 2 teeth which require pulpotomy treatment. After removing of carious teeth by a low speed round bur and pulp exposure, roof of pulp chamber is removed completely by a high speed 008 fissure bur. Life tissues of pulp are removed by sharp excavator and rinsing with normal salin. Hemostat is achieved and cavity will be cleaned by 0.5% hypo chlorate solution. MTA or NEC material is mixed according to manufacturer instruction and will be placed in pulp chamber and over pulpal canal orifices for at least 1 mm. The light cure glass inomor is also mixed according to manufacturer instruction and is places over the A or B material and cured for 40 minutes.
