Comparative Evaluation of Ozonoid Olive Oil and Calcium Hydroxide as an Indirect Pulp Capping Agent in Primary Mandibular Second Molar: A Randomized Controlled Trial
J Contemp Dent Pract
Aim: The aim of this study was to evaluate clinical and radiographical success of ozonoid olive oil as an indirect pulp capping (IPC) agent in primary mandibular second molar when compared to calcium hydroxide and to evaluate the antimicrobial efficacy of ozonoid olive oil on Streptococcusmutans and Lactobacilli.
Materials and methods: A split-mouth randomized controlled trial was conducted on 30 primary mandibular second molars in 15 children of age 5-9 years with deep dentinal carious lesion. Teeth were randomly allocated to two groups of 15 each. After achieving local anesthesia and rubber dam isolation, an IPC procedure was performed using ozonoid olive oil in group I and calcium hydroxide in group II. Teeth were evaluated clinically and radiographically at 6 and 12 months of follow-up for success or failure of IPC. The bacterial counts of S. mutans and Lactobacilli were measured before and after application of ozonoid olive oil for 60 seconds on dentinal tissue in group I and recorded as colony-forming units per mL (CFU/mL).
Results: There were no statistically significant differences found between the materials used for IPC (p >0.05). About 93.33% and 100% clinical and radiographical success rates were seen in group I and group II, respectively. Statistically significant differences were observed for bacterial reduction after the application of ozonoid olive oil (p <0.05) for both the microorganisms.
Conclusion: The results of this study showed that the success of IPC is independent of capping material. Ozonoid olive oil, an antimicrobial agent, can also be used for IPC. The success of the IPC procedure depends on a reduction in the bacterial count and sealing of the tooth with hermetic restoration. More clinical studies with a larger sample size and longer follow-up duration are required for understanding the efficacy of this material.
Clinical significance: Ozonoid olive oil can be used as an IPC agent in primary molars and also for a bacterial reduction in dentinal caries.
