Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: pulpectomy procedure and the clinical evaluation
Description: in this study, pulpectomy procedure was performed in a single visit and the root canals were filled with different obturating materials. The clinical follow up evaluation was carried out after three, six and twelve months after pulpectomy procedures. The teeth were clinically evaluated each follow up visit for the following clinical features: absence of spontaneous pain, no tenderness with percussion, no abnormal mobility and absence of swelling \& sinus or fistula. If the tooth exhibited any one of above clinical features, the pulpectomy was considered to be a failure (F); otherwise, it was regarded as clinical success (S).

Group type: EXPERIMENTAL
Intervention: radiographic evaluation
Description: Radiographic evaluation was performed immediately after teeth restoration (base line radiograph), then after three, six and twelve months. The parallel periapical technique was performed using the rinn (XCP) periapical film holder and a long cone which was mounted to the x-ray tube. The criteria for radiographic success were no evidence of extensive pathologic root resorption, reduction or no change in pre-operative pathologic inter-radicular radiolucency and no evidence of new postoperative pathologic radiolucency.
