简要总结
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.
详细描述
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.

主要结局
clinical success of primary molar pulpectomy after using new root canal filling materials (Zinc Oxide-Ozonated olive Oil , Zinc Oxide- olive Oil) compared to the widely used material (zinc oxide material)
时间窗: 12 months
by assessing the presence or absence of spontaneous pain, presence or absence of tenderness with percussion, presence or absence of abnormal mobility and presence or absence of swelling and/or fistula during the follow-up intervals ( three, six and twelve months )
radiographic success of primary molar pulpectomy after using new root canal filling materials (Zinc Oxide-Ozonated olive Oil , Zinc Oxide- olive Oil) compared to the widely used material (zinc oxide material)
时间窗: 12 months
by assessing the presence or absence of extensive pathologic root resorption, reduction or no change in pre-operative pathologic inter-radicular radiolucency and presence or absence of new postoperative pathologic radiolucency. the assessment is done using periapical radiographs at three, six and twelve months after pulpectomy procedure.
