Evaluation of Periapical Granuloma and Radicular Cyst Regarding the Age, Gender and The Lesion Size

Background: Apical periodontitis (AP) is a common infectious disease characterized by inflammation and bone destruction in the periapical tissues due to microbial infection in the dental pulp . AP is the most frequent inflammatory lesion related to teeth, distinguished by a direct pathway to the bone marrow without epithelial barriers if the dental pulp becomes necrotic and infected. Materials and methods: Thirty paraffin embedded tissue blocks of radicular neck resected samples of 18 preapical granulomas and 12 radicular cysts were processed histopatholgically. Results: the mean patients’ age was 34.37 ± 2.95 years; fifteen patients were aged bellow 30 years and 15 patients were equal or above 30 years. The mean lesions size was significantly higher among patients with radicular cysts than preapical granuloma (5.07 ± 1.35 vs. 0.94 ± 0.21; p=0.048. granulomas lesions were slightly higher among females in age group 30-39 years ( 25% vs. 10%), and the radicular cysts lesions were higher among females in all age group as compare to male patients Conclusions: Lesions size was significantly higher among patients with radicular cysts than that of preapical granuloma. A peak incidence between the third and fourth decades of life and predominance among female
