NCT07265089

Brief Summary

This randomized clinical trial compares zinc oxide-ozonated olive oil and Metapex as root canal filling materials in primary anterior teeth of children aged 3-5 years. The study aims to evaluate their clinical and radiographic success over 12 months.Clinical evaluation includes pain, swelling, and mobility; radiographic evaluation includes periapical healing and resorption.

Outcome Measures

Primary Outcomes (1)

  • Clinical success: absence of pain, swelling, tenderness, or mobility

    12 month intervals T0: 0 T1: 3month T2: 6month T3: 9month T4: 12month

Secondary Outcomes (1)

  • Radiographic success: absence of periapical radiolucency or root resorption

    12 month intervals T0:0 T2: 6 month T4: 12month

Study Arms (2)

Group A Zinc Oxide-Ozonated Olive Oil

EXPERIMENTAL

Zinc oxide powder will be mixed with ozonated olive oil until a creamy, workable consistency is achieved.

Other: Zinc Oxide-Ozonated Olive Oil

Group B Metapex

EXPERIMENTAL

Premixed calcium hydroxide with iodoform paste

Other: Metapex

Interventions

Children aged 3-5 years with primary anterior teeth requiring pulpectomy will receive treatment under rubber dam isolation. After achieving local anesthesia, an access cavity will be prepared using sterile round burs with water coolant. Working length will be determined using an apex locator, and biomechanical preparation will be performed with K-files.Irrigation will be done with normal saline and 1% sodium hypochlorite, followed by drying with paper points. The canal will then be obturated with a freshly prepared mixture of zinc oxide powder and ozonated olive oil placed using a lentulo spiral, avoiding overfilling. The access cavity will be sealed with glass ionomer and restored with light-cured composite. Follow-up will occur at 3, 6, 9, and 12 months.

Working length will be determined using an apex locator, and biomechanical preparation will be performed with K-files.and irrigation with normal saline and 1% sodium hypochlorite. After drying, the root canal will be filled with Metapex (premixed calcium hydroxide and iodoform paste) delivered via syringe with a fine tip until proper fill is confirmed radiographically. The canal will then be sealed with glass ionomer and restored with light-cured composite. Follow-up will be performed at 3, 6, 9, and 12 months.
