Comparative Clinical and Radiographic evaluation of Zinc oxide Ozonated Olive Oil as Obturation material in Primary molars with different Obturation techniques: An In vivo Study

This study is a randomized, double-blind, parallel-group in vivo clinical trial evaluating zinc oxide mixed with ozonated olive oil as an obturation material in primary mandibular molars of children aged 4–8 years. A total of 40 children requiring pulpectomy will be included and randomly allocated into two groups, 20 in each. The intervention group will receive obturation using the Navitip syringe technique to deliver the zinc oxide–ozonated olive oil mixture into the prepared canals. The comparator group will receive obturation using the Lentulo spiral technique with the same obturating material. The primary outcome includes evaluation of the quality of obturation in terms of fil that includes optimal fil, underfil, or overfil)and presence of voids. Secondary outcomes will include clinical and radiographic evaluation of obturation quality based on length of filling  and the presence of voids during follow-up.
