NCT02201641

Brief Summary

This study aims to investigate the tooth nerve response to a recently introduced therapeutic filling material (calcium silicate cement) called Biodentine and to assess the quality of the overlying filling compared to another material (glass ionomer cement) called Fuji IX used more commonly. Also to compare the effectiveness of cone beam computed tomography x-rays compared to conventional periapical x-rays in detecting lesions around these teeth.

Outcome Measures

Primary Outcomes (1)

  • The principal outcome of the study is whether the tooth restored with the test or control material remains vital (alive) at follow-up examination.

    The vitality of the restored tooth (whether the nerve of the tooth is alive or dead) is determined clinically by a positive response to cold test, absence of spontaneous pain, negative sensitivity to percussion, absence of sinus/fistula/swelling and abnormal mobility, and absence/reduction of periapical radiolucencies as determined by PA radiographs.

    up to 2 years

Secondary Outcomes (2)

  • The integrity of the composite restoration overlying the test or control material is either acceptable or not.

    up to 2 years

  • The CBCT scans of the teeth restored with the test or control material are either more effective or are comparable to conventional radiographs in detecting the presence of early peri-radicular lesions associated with the restored teeth.
