NCT03732170

Brief Summary

The study design is a double blinded randomized controlled trial and 170 subjects (teeth) , 85 in each of the 2 groups, will be enrolled from the patients at the NUH dental centre endodontic unit. The study aims to assess how the use of TotalFill® bioceramic sealer affects the healing outcome of apical periodontitis compared to a control AH plus®. Conventional root canal treatment will be done during this study. Radiographs will be taken at each study visit during the study for root canal. The preoperative, postoperative and review clinical and radiographic data will be analysed.

Outcome Measures

Primary Outcomes (1)

  • Change in the status of periapical lesion size

    Proportion z-test will be carried to compare the proportion of study subjects with improved apical lesion size between the two treatment groups. Odds ratio with 95% confidence interval will be reported. Logistic regression analysis adjusted for the stratification variables (gender) and other confounding factors (namely patency, extrusion of sealer or GP, short fill, voids, pre-op apical size, pre-op clinical symptoms and number of C\&S visits).

    comparison of the periapical lesion size at baseline, 6 month and 12 month

Secondary Outcomes (1)

  • Comparison of the pain score of post-op pain

    Day 1, Day 3 and Day 7 post treatment

Study Arms (2)

TotalFill® Bioceramic sealer

EXPERIMENTAL

It will be used in conjunction with TotalFill® bioceramic impregnated gutta percha points for the obturation of root canals. It is dispensed through a fine disposable syringe into the root canals during obturation.

Device: TotalFill® Bioceramic sealer

AH plus® sealer

ACTIVE COMPARATOR

It consists of 2 pastes that are mixed together in equal amounts before it is used in conjunction with gutta percha points for obturation during root canal treatment.

Device: AH plus® sealer

Interventions

The participant will be treated with TotalFill® Bioceramic sealer.

Eligibility Criteria

Age21 Years - 95 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • A preoperative periapical radiograph will be required for diagnosis.
  • Subjects at least 21 years old.
  • Medically healthy
  • In a patient with multiple teeth requiring root canal treatment, only 1 tooth from each side will be included and selected at random.

You may not qualify if:

  • Patient below 21 years old
  • Pregnant women.
  • Patients with autoimmune diseases and uncontrolled diabetes.
  • Teeth with periodontal probing depths of 5mm or more.
  • Incomplete root formation that is detected radiographically.
  • Cracked teeth
  • Teeth are deemed to have poor restorative prognosis.
  • Teeth with adjacent teeth on the same side that require root canal treatment
