Abstract: Objective: The aim of the present study was to verify the prevalence of the cystic and non-cystic lesions, with varied degrees of abscess severity, in teeth bearing periapical lesions associated to the dental apex at the time of their extraction. Material and methods: In order to do so, semi-serial cuts were conducted in 102 periapical lesions which were then dyed by the HE technique. The lesions were classified by two observers in periapical granuloma, 1,2 and 3 degrees periapical abscess, 1,2 and 3 degrees periapical cyst and abscessed cyst. After undertaking this first analysis, the lesions were then grouped in non-cystic of minor severity of abscess (periapical granuloma and 1 degree abscess) and major severity (2 and 3 degrees abscesses) and in cystic lesions of minor severity (1 degree periapical cyst e abscessed cyst) and major severity of abscess (degrees 2 and 3 abscessed cysts). Results: The cysts totaled 24,5% of the sample and 84% of them presented high degrees of severity. The most prevalent histological diagnosis (63,7%) was the one of degrees 2 and 3 periapical abscess, i.e., non-cystic lesions with high degrees of abscess. Conclusions: It was thus concluded that the cystic lesions add to nearly 24,5% of the periapical pathologies associated to radicular canal necrosis and that the majority of the chronic periapical lesions (84,3%), independently of being cystic (20,6%) or non-cystic (63,7%), show severe degrees of abscess.
