Zinc Oxide-Ozonated Olive Oil vs Metapex in Primary Anterior Teeth

Dental caries in primary anterior teeth significantly compromises aesthetics and function, particularly affecting children's psychosocial well-being and oral development. Esthetically, carious lesions in these visible teeth can lead to social avoidance, reduced self-esteem, and bullying risks, as children may avoid smiling or participating in activities. Pulpectomy of primary teeth is a critical to maintain arch integrity, function, and aesthetics in the pediatric population. Zinc oxide eugenol (ZOE) has been the most commonly used filling material in pulptherapy of primary teeth, achieving moderate to high success rates exceeding 90%. However, the slow resorption rate, which may not match the physiological root resorption of primary teeth, potentially leading to delayed natural exfoliation and complications with the eruption of permanent successors. it can also induce necrosis and delayed healing.

(ZOE) can cause irritation and sensitivity when in contact with oral tissues, primarily due to the eugenol component. Eugenol is recognized as a sensitizer and can induce both localized irritation and hypersensitivity reactions, including contact dermatitis, contact stomatitis, and, in rare cases, immediate allergic responses such as urticaria and generalized itching shortly after application.

Olive oil is a vegetal oil it contains antioxidants that enhance properties which can potentially overcome the limited antimicrobial activity of traditional ZOE. Ozonated olive oil has demonstrated excellent biocompatibility with surrounding tissues. This reduces the adverse reactions or irritation, making it a safer alternative for pediatric patients. Zinc oxide-ozonated olive oil may reduce the chances of overfilling and subsequent eruption complications. Promotes tissue repair and healing due to its anti-inflammatory and regenerative properties. This can contribute to quicker recovery and better clinical outcomes.
