Clinical Post-operative Assessment of Chronic Signs & Symptoms Related to Infected Primary Molars After Using Rotary Versus Manual Systems in Cleaning the Root Canals

Not Applicable

• Conditions: Chronic Infection

• Registration Number: NCT03684915
• Lead Sponsor: Cairo University

Brief Summary

One of the most important concerns in pediatric dentistry is the loss of necrotic primary molars leading to space loss. pulpectomies for primary teeth with severe pulpal involvement should be considered as the treatment of choice.

Bacteria plays an essential role in the initiation and perpetuation of pulpal and periapical disease. The investigator's target when cleaning and shaping the root canal system is to remove bacteria-containing tissue.

The removal of organic debris is the main purpose of instrumentation in pulpectomy procedures in primary teeth, this could be achieved using manual or rotary Ni-Ti files. A practical pulpectomy technique for the primary teeth should include the following:1) Fast procedure with short treatment time and minimal number of appointments.2) Effective debridement of the root canal without weakening the tooth structure or endangering the underlining permanent teeth.3) Minimal procedural complications. 4) Maintaining tooth function until it is naturally exfoliated.

Manufacturers using rotary files highlight their cleaning efficiency for root canal preparations, simple procedures, and decreased procedure time, which is especially important in children.

Considering that preparation time is an important clinical factor in pediatric patient management, the use of rotary instruments for pulpectomies in primary teeth is recommended.
