NCT03717337

Brief Summary

This study evaluates success rate of non vital mature anterior teeth with periapical lesion treated by regenerative endodontic protocol in single visit versus two visit technique. Patients are randomized into two groups where treatment will be done either in one visit including access, disinfection, placing platelet rich plasma as scaffold and restoration or two visit protocol involving access, disinfection and placing calcium hydroxide as intracanal medicament in first visit followed by a second visit after 3 weeks involving reopening of the tooth, removing intracanal medicament and placing platelet rich plasma as scaffold then restoration. Success rate is defined as absence of subjective signs and symptoms along with healing of periapical lesion

Outcome Measures

Primary Outcomes (3)

  • Change in Post operative pain: NRS

    absence of pain reported by the patient by numerical rate scale, the 11-point numeric scale ranges from '0' representing one pain extreme (e.g. "no pain") to '10' representing the other pain extreme (e.g. "pain as bad as you can imagine" or "worst pain imaginable")

    3, 6, 9 and 12 months

  • Change in swelling and/or sinus

    The presence of swelling or sinus will be reported by a binary question yes/no

    3,6,9,12 months

  • Periapical healing

    The existing periapical lesion will be measured by mm by CBCT before intiation of treatment and after one year

    12 months

Secondary Outcomes (3)

  • Antimicrobial effect

    before and after complete disinfection either in the same visit or after 3 weeks from the second visit

  • Sensitivity

    3, 6, 9 and 12 months

  • Discoloration

    3, 6, 9 and 12 months

Study Arms (2)

Single visit pulp regeneration

EXPERIMENTAL

Regenerative endodontic procedure not involving placement of intracanal medicament will be done in single visit

Procedure: Single visit pulp regeneration

Two visit pulp regeneration

ACTIVE COMPARATOR

Regenerative endodontic procedure involving placing intracanal medicament will be done in two visit

Procedure: Two visit pulp regeneration

Interventions

Access cavity, disinfection, preparing and injecting platelet rich plasma, and restoring the tooth all done in one visit.

Single visit pulp regeneration

first visit : access, disinfection and placing calcium hydroxide as intracanal medicament second visit: re opening of tooth, preparing and injecting platelet rich plasma and restoring the tooth.

Two visit pulp regeneration
