Primary and recurrent periapical granuloma and cyst clinical and histochemical study

ABSTRACT

Clinical examination of 180 cases with periapical granulomata and cysts showed that the maxilla was more frequently affected. A higher incidence was found in patients under 20 years age, with a greater rate of recurrence after surgical treatment. Histochemical study lessens the possibility of infection to be the primary cause of recurrence and epithelial remnants were suggested
