Outcome Measures

Primary Outcomes (1)

  • Clinical and radiographic success

    Criteria of clinical success: Absence of pain and tenderness to palpation/ percussion, absence of sinus or any associated soft tissue swelling, tooth mobility of grade-I or less, and no deterioration in periodontal probing depth as compared with baseline measurements Criteria of radiographic Success: PAI score 1-Normal periapical structures, OR PAI Score 2-Small changes in bone structure. Criteria of radiographic Failure: PAI score 3-Changes in bone structure with some mineral loss, OR PAI Score 4-Apical periodontitis with well-defined radiolucent area, OR PAI Score 5-Severe periodontitis with exacerbating features

    Baseline to 1 year

Secondary Outcomes (1)

  • Pain assessment

    Baseline to 7days

Study Arms (2)

single visit retreatment

EXPERIMENTAL

nonsurgical root canal retreatment will be carried out in single visit.

Procedure: Non surgical Single visit Retreatment

multi visit retreatment

ACTIVE COMPARATOR

In this group,GP removal and biomechanical preparation will be carried out in first visit,after which calcium hydroxide dressing will be placed and temporarily restored.after 7 days,in second visit obturation will be done followed by permanent restoration

Procedure: Multi visit Retreatment with calcium hydroxide dressing

Interventions

Non-surgical endodontic retreatment will be carried out in single visit.

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patient willingness to participate in the study.
  • Previously root filled Permanent teeth with post-treatment apical periodontitis requiring nonsurgical root canal retreatment.
  • Failure of previous root canal treatment will be determined based on clinical and radiographic findings. Clinical indicators of failure will include pain, tenderness to palpation/percussion, swelling, sinus tract.Radiographic criteria will include persistent periapical radiolucent lesions in teeth in which initial treatments were performed at least 4 years previously.
  • Root canal fillings no more than 4mm short of the apex.
  • Patients showing no significant systemic disease

You may not qualify if:

  • Patients who are pregnant, diabetic, immunocompromised, serious medical illness or requiring antibiotic premedication.
  • Patient under 18 years of age.
  • Patient under corticosteroid use.
  • Patients with history of antibiotic use in last 3 months or analgesic use in last one week will also be excluded.
  • Multiple teeth that require treatment to eliminate the possibility of pain referral.Patients with unrestorable carious lesions, fractures involving the periodontium, and/or periodontal pockets ≥ 4mm deep or having marginal or furcal bone loss due to periodontitis .
  • Teeth with the procedural errors preventing access to apical third and missed canals will be excluded.
  • Teeth that are not suitable for rubber dam isolation.
  • Teeth with intraradicular post.
