Purpose: To evaluate the response to the Sargenti technique and filling material (RC-2B) at 6 months and 1 year after treatment N= 30 teeth in 3 monkeys
•Pulpitis was induced in 16 teeth (9 treatment/7 control) pulp exposed for 48h
•Necrosis was induced in 18 teeth (9 treatment/9control) pulp exposed for 2 months
–In teeth with pulpitis: no irrigation, instrumentation with largest that bind to the apical third, then RC-2B was inserted to the deepest level with a lentulo spiral until the canal was sufficiently filled.
–In the necrosis group: the same procedure performed, but the preparation and sealer was carried to the CDJ.
•The teeth were observed for 6 month and 1 year periods, then the animals was killed and the jaws sectioned for histologic evaluation.
Most highlighted Results:
•None of the pulpitis control teeth had any periapical inflammation. •Periapical pathosis was evident in all teeth treated for pulpitis at 6 months and 1 year after tx. (granuloma, granuloma abscess, root resorption).
•The treated and untreated specimens showed the same periapical responses. (granuloma, abscess, osteomyelitis, periapical cyst).
The long-term response of treated teeth to Sargenti’s technique and materials was unfavorable
