Primary tooth preservation in a functional condition until its normal shedding is highly important in pediatric dentistry [In this study, other vehicles were mixed with zinc oxide powder as ozonated olive oil which was chosen because ozone is unsteady in a gaseous state and needs special equipment to be present chairside, and when ozone liquifies in water, it quickly breaks down, making it impossible to store [The present study results accepted the null hypothesis as there was no statistically significant difference regards the overall clinical success of the three groups at all follow-up periods, whereas a significant difference was observed regarding furcal bone radio-density among the study groups at all follow-up periods (null hypothesis was partially rejected). The overall clinical evaluation of ozonated olive oil group at all follow-up periods revealed excellent clinical signs of success; this promising clinical outcome could be explained by ozone peroxides’ potent antibacterial effects and excellent healing characteristics. The ozonated olive oil’s antimicrobial activity may be due to the effects of aldehydes, unsaturated fatty acids, and hydrogen peroxide on anaerobic bacteria frequently detected in endodontic infection [Regarding the olive oil group, the overall clinical success at all follow-up times revealed comparable results to ozonated olive oil group; this agreed with Feier et al. [In this study, the overall ZOE group evaluation reported an acceptable clinical success rate at all follow-up periods; this may be explained by the anti-inflammatory and analgesic properties of eugenol since the released-eugenol amount instantly after application in the periapical zone is 10No significant statistical difference among the three groups was detected at 3, 6, and 12 months with a satisfactory clinical success rate; this excellent overall outcome might be attributed to careful case choice, appropriate protocols, and proper material usage. Additionally, the stainless-steel crowns offer the best coronal seals against microbial leakage in primary molars. Ozonated olive oil group & olive oil group had a considerable clinical success rate than the ZOE group with no statistically significant difference; this agreed with Nardi et al. [Regarding furcal bone radio-density, a statistically significant difference was observed at the 3, 6, and 12-month follow-up intervals among the study groups with a progressive furcal bone regeneration in the ozonated olive oil group; this agreed with Feier et al. [To the best of our knowledge, this is the first study assessing ZO-ozonated olive oil paste compared to olive oil and ZOE as primary root canal filling materials. According to the results of this study, ZO-ozonated olive oil paste can be a substitute for ZOE, producing acceptable clinical and radiographic outcomes. Even so, more clinical, and histologic research with a longer follow-up period is required to reach definitive conclusions. The present research has limitations, including a small sample size and short follow-up periods while its results can be used as a basis for future studies. Moreover, the effect of tested materials on exfoliation time was not measured which can be done in upcoming randomized clinical trials with long-term evaluation periods before a reliable conclusion can be drawn as the best root canal filling material for primary teeth. Also, the concentration of ozone in ozonated olive oil was not given in this study which may produce unexpected oxidative reactions at different concentrations of ozone, so further experiments are necessary to investigate this effect.
