Root canal therapy (RCT) and tooth extraction have been conventional treatment options for management of human mature teeth with irreversible pulpitis. Excellent short-term treatment outcomes of vital pulp therapy with calcium-enriched mixture cement (VPT/CEM), as a new treatment option, on postoperative pain relief was demonstrated; if intermediate- and long-term treatment outcomes of the new treatment are also non-inferior compared to RCT, then VPT/CEM may become a viable treatment option for management of mature teeth with irreversible pulpitis.

Materials and methods

In 23 healthcare centers, 407 9- to 65-year-old patients were randomly allocated into two study arms including one-visit RCT (reference treatment; n = 202) and VPT/CEM (alternative treatment; n = 205). Six- and twelve-month clinical and radiographic successes were assessed.


Mean follow-up times at 6- and 12-month follow-ups were “6.70 ± 0.68 and 6.72 ± 0.71 months” and “12.96 ± 0.67 and 12.90 ± 0.66 months” in the available cases of RCT and VPT/CEM arms, respectively. Favorable clinical success rates in the two study arms did not show statistical difference; however, the radiographic success rate in the VPT/CEM was significantly greater than RCT arm at the two follow-ups (P < 0.001). The patients’ age had no effect on the treatment outcomes (P = 0.231).


Treatment outcomes of VPT/CEM may be superior to RCT in mature molars with irreversible pulpitis. The performance of biomaterials such CEM cement may assist in the shift towards more biologic treatments.

Clinical relevance

VPT/CEM may be a realistic alternative treatment for human mature molar teeth with symptoms of irreversible pulpitis; the use of VPT/CEM is highly beneficial for patients as well as general dentists.
