Non vital teeth with periapical cysts do not respond to routine root canal therapy alone. Conventional RCT (root canal therapy) should be combined with conservative management of cysts or surgical management. Contemporary options for non-surgical management are repeated intra canal dressing with Ca (OH)2, aspiration and decompression techniques. Repeated intra canal dressing with Ca(OH)2 and Iodoform (Metapex) was advocated in 15 of our patients for a period of eight years from 2011-2019. The healing of the lesions was excellent with respect to bone formation, reestablishment of periodontal ligament and reduction in tooth mobility on follow up of six months to one and a half years. This case series gives insight of successful non-surgical management of periapical cysts. We reiterate the effectiveness of non-surgical management of periapical cysts as it was well observed in our case series. The promising prognosis of non-surgical management of periapical cysts can render the surgical options antediluvian.
