The Success Rate of Cryotherapy Application in Primary Molars With Signs of Irreversible

The study is designed as a randomized controlled trial with two parallel groups. Children aged 5-9 years with primary molars from suffered symptomatic signs of irreversible pulpitis will be randomly assigned into two groups. The first group (experimental group) will be injected with 4% articaine 1:100.000 epinephrine (inferior alveolar nerve block). For the second group, the mandibular second primary molars will be anesthetized using 4% articaine 1:100.000 epinephrine using inferior alveolar nerve block.
