Introduction: Induction of labor is the nonspontaneous initiation of uterine contraction to accomplish delivery prior to the onset of spontaneous labor. Induction of labor at term is a common obstetric intervention and cervical ripening in these cases is considered to be of importance. Aims: The aim of the present study was to compare efficacy and safety of two dinoprostone preparations and Laminaria tent in induction of labor. Materials and Methods: One fifty pregnant women were randomized and assigned for induction with Dinoprostone intracervical gel, Dinoprostone sustain release vaginal pessary and Laminaria tent according to inclusion and exclusion criteria. The study was carried out at Agartala Government Medical College & GBP Hospital, in the department of Obstetrics & Gynaecology from 1st January 2020 to 30th June 2021. Result: It has been observed that in our study Dinoprostone gel had shorter mean induction to delivery interval In comparison to Dinoprostone pessary and Laminaria tent which is statistically significant. The mean induction to delivery interval in D.gel group is 16.33±2.16 hours whereas D.pessary and Laminaria tent had 18.38±2.14 hours and 24.22±2.21 hours mean induction to delivery interval respectively. Though Dinoprostone gel had shorter mean induction to delivery interval in comparison to Dinoprostone pessary but that is not statistically significant that means they are alike. Conclusion: Though sometimes inconvenience might be encountered with the repeated application of Dinoprostone gel in comparison to Dinoprostone pessary and Laminaria tent, with the potential risk of infection which could be prevented by taking all precautions, yet outcome of Dinoprostone gel outweigh these disadvantages
