Background

Pulpal treatment is delivered with the aim of preserving the integrity and health of oral tissues. Pulpectomy helps in retaining primary teeth that have irreversible pulp pathosis without symptoms and has a high success rate. However, it is also associated with complications related to the primary dentition’s complex root canal morphology, inherent physiologic root resorption, close proximity to permanent successors, difficulty visualizing tooth apices radiographically, complicated diagnosis

Methods

The clinical and radiographic success rates of RC Fill, Vitapex, and Pulpdent root canal sealer were investigated in a population of 4- to 9-year-old children whose primary mandibular molars had necrotic pulps or irreversible pulpitis. The 90 children (129 teeth) were randomly assigned to receive RC Fill (ZOE plus iodoform), Vitapex (calcium hydroxide), or Pulpdent root canal sealer (ZOE). Outcomes defined by modified American Association of Endodontists (AAE) criteria were evaluated clinically

Results

Twelve percent attrition left 90 teeth to assess at 30 months, but at the 6-, 12-, and 30-month evaluations, all three materials were associated with 100% clinical success. None of the teeth developed new lesions. Teeth demonstrated regeneration and reduction in the size of the furcation and periapical radiolucencies. However, thickening of the lamina dura and widening of the periodontal ligament space were observed in some cases, which were considered failures. As a result, the overall

Discussion

The three materials provided equally effective root filling performances for up to 30 months in these primary teeth with necrotic pulps or irreversible pulpitis.

Clinical Significance

The current root filling materials are comparable in their ability to perform successfully for up to 30 months. Long-term follow-up data are needed to detail their performance until permanent teeth erupt and replace these primary teeth.
