Efficacy of different pulpotomy procedures in permanent molars with symptomatic irreversible pulpitis: a retrospective study

This study aimed to retrospectively evaluate the effects of different disinfection and hemostasis procedures on the outcome of mineral trioxide aggregate (MTA) pulpotomy in permanent molars with symptomatic irreversible pulpitis (SIP). This retrospective study included patients who had permanent carious molars diagnosed with SIP and treated with MTA pulpotomy under different hemostasis and disinfection procedures (saline, NaOCl, and potassium titanyl phosphate (KTP) laser) by the same operator in the 2-year period. The treatment records of 161 patients diagnosed with SIP in their permanent teeth and treated with total pulpotomy. In total, 96 patients were excluded. Sixty-five patients with at least 12-month of follow-up were evaluated. Patients were between the ages of 15–54. The overall success rate was 87.69% (57/65) in 12-month follow-up. The success rates for hemostasis and cavity disinfection procedures were 86.4% (19/22) for saline, 86.4% (19/22) for NaOCl, and 90.5% (19/21) for KTP laser with no statistically significant difference (P > 0.05). According to our data; the effect of age, bleeding time, and periapical lesion on the success rate was not significant. Dentin bridge formation was detected in 4 teeth (2 PS, 2 KTP laser) and pulp obliteration in 1 tooth (KTP laser). MTA pulpotomy is an effective treatment for permanent molars with SIP. Physiological saline, NaOCl, or KTP laser can be used in MTA pulpotomy.
