Metapex a material used widely today in pulpectomy treatment of deciduous teeth. A comparison between Metapex and Endoflas as root canal obturating material was presented. Sixty children with age range from four to seven years were participating in the research, selected from the pediatric dentistry department in Delta hospital, Delta university. Restorable non-vital deeply decayed primary first mandibular molars indicated for pulpectomy with previous spontaneous pain and pulp exposure were selected. Radiographically, the teeth selected were presented with inter-radicular and peri-radicular radiolucency's. The selected teeth were separated into two groups each of them consists of 30 teeth:
Group 1, the canals filled with Metapex. Group 2, the canals filled with endoflas.
Endoflas showed the higher percentage of Flush-filled obturated roots (93.3%), with no cases of overfilled roots. Additionally, 80% of Metapex treated teeth were flush filled in comparison to 10% with overfilling. No statistically significant difference is detected between studied groups as regard flush-filled, underfilled, and overfilled materials. Non statistically significant difference is detected between the two groups Metapex and endoflas regarding clinical and radiographic rate of success which is higher in group Metapex than endoflas (90% versus 80%, respectively). Clinical and radiographic finding were evaluated among studied groups at each follow up period.
Metapex appears to be an effective treatment more than endoflas in pulpectomy procedures. Other studies may be needed in the future to compare Metapex with the other obturating materials in deciduous teeth.
