Clinical & Radiographic Evaluation of Zinc Oxide-Ozonated Oil as a New Primary Root Canal Filling
Study Details
Study Description
Brief Summary
Preserving primary teeth is essential for many aspects such as the child's growth and development, esthetic, functional, psychological, and dental arch integrity aspects. a randomized blinded controlled clinical trial aimed to evaluate the clinical and radiographic success of Zinc Oxide-Ozonated Olive Oil as root canal filling materials for primary molars compared to Zinc Oxide-Olive Oil & Zinc Oxide-eugenol. 90 primary molars of 30 children aged between 4-8 years with pulpally involved primary molars, are equally divided into 3 groups which treated with Zinc Oxide-Ozonated Olive Oil , zinc oxide -olive oil and zinc oxide eugenol as obturation materials following pulpectomy procedure. The subjects were followed up clinically and radiographically at 3, 6 and 12 months.

Detailed Description
Pulpectomy for primary teeth involves root canal preparation followed by obturation with a resorbable material. Zinc oxide eugenol (ZOE) is the most widely used obturating material. The main ZOE disadvantages are the difference in rate of resorption compared to the root, and limited antimicrobial activity. ZOE is formed when crude eugenol is mixed with zinc oxide. the set material easily hydrolyzes, resulting in free eugenol release which can be harmful to human soft tissues; this motivated the search for a new eugenol substitute to be combined with zinc oxide. Olive oil is a vegetable oil that comprises antioxidants, carotenoids, oleuropein, and oleocanthal, a phenolic component that significantly contributes to its antibacterial and anti-inflammatory properties. ozone in the form of ozonated olive oil, have the ability to produce nascent oxygen deep into the treated area without triggering irritation so, improved rheological characteristics, increased intracellular ATP, stimulated cellular metabolism, and expression of cytokines related to healing, particularly Transforming Growth Factor.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: group 1: zinc oxide-ozonated olive oil Group I: 30 primary molars were filled with fresh mix of zinc oxide powder with ozonated olive oil A single-visit pulpectomy procedure was performed . Standardized preoperative periapical radiograph was obtained to assess tooth condition & proper selection. Teeth were anesthetized & Rubber dam isolation was done, then all caries was removed & access opening was gained. Working length was determined by apex locator. All canals were prepared using Kidzo file system in a lateral brushing motion with an Endo-Mate DT endodontic motor at 350 RPM and 2.5 N/cm torque. EDTA gel 17% will be used before instrumentation & irrigation was done with normal saline. Dryness with paper points size 30 . placement of the root canal filling material (zinc oxide-ozonated olive oil) was applied . Intermediate restorative material was placed, then tooth was restored with stainless-steel crown |
Procedure: pulpectomy procedure and the clinical evaluation
in this study, pulpectomy procedure was performed in a single visit and the root canals were filled with different obturating materials. The clinical follow up evaluation was carried out after three, six and twelve months after pulpectomy procedures. The teeth were clinically evaluated each follow up visit for the following clinical features: absence of spontaneous pain, no tenderness with percussion, no abnormal mobility and absence of swelling & sinus or fistula. If the tooth exhibited any one of above clinical features, the pulpectomy was considered to be a failure (F); otherwise, it was regarded as clinical success (S).
Other Names:
Radiation: radiographic evaluation
Radiographic evaluation was performed immediately after teeth restoration (base line radiograph), then after three, six and twelve months. The parallel periapical technique was performed using the rinn (XCP) periapical film holder and a long cone which was mounted to the x-ray tube. The criteria for radiographic success were no evidence of extensive pathologic root resorption, reduction or no change in pre-operative pathologic inter-radicular radiolucency and no evidence of new postoperative pathologic radiolucency.
