Clinical and radiological analysis of a series of periapical cysts and periapical granulomas diagnosed in a Brazilian population

Abstract

BackgroundPeriapical cysts (PC) and periapical granulomas (PG) are the two most common chronic inflammatory periapical diseases, but their clinicoradiological characteristics can vary depending on the methods employed in each study. The aim of the present work was to analyze the clinical and radiological profile of a series of PC and PG diagnosed in a Brazilian population.Material and MethodsThe files of two Oral Pathology laboratories were reviewed and all cases diagnosed as PG and PC were selected for the study. Clinical and radiological information were retrieved and data were tabulated and descriptively and comparatively analyzed.ResultsFinal sample was composed by 647 inflammatory periapical lesions, including 244 PG (38%) and 403 PC (62%). The number of women affected by PG was significantly higher than the number of women affected by PC (p=0.037). Anterior region of the maxilla was the most common affected area for both entities (39% of the cases), but the most common anatomical location of PG (anterior maxilla and posterior maxilla) was different from PC (anterior maxilla and posterior mandible) (p<0.0001). Upper lateral incisor was the most affected tooth. The mean radiological size of the PC was larger than the mean radiological size of the PG (p<0.0001) and PC showed well-defined radiological images more frequently than PG (p<0.0001).ConclusionsPC were more common than PG, both showed predilection for adult females, most lesions affected predominantly the anterior maxilla and PC presented larger mean radiological diameter and well-defined images when compared with PG. Key words:Periapical granuloma, periapical cyst, radicular cyst, diagnosis, Oral Pathology.

“…The results also showed statistically significant mean student's score in group I receiving the program CD containing the images with MCQ after lecture compared to the other group II. This results is beneficial in the field of diagnosis and it is in accordance with the prevalence of this lesion as Tavares et al (2017) [34] were concluded that periapical granulomas were most frequently diagnosed from biopsies submitted by endodontist following apical surgery followed by radicular cyst, scars and other diagnoses.…”

Clinicopathological and ultrastructural characterization of periapical actinomycosis

“…Nonetheless, it can be substantially underreported, considering the number of periapical surgical specimens that are not submitted to histopathological analysis after removal, as well as the differences on reporting these lesions by different oral pathology laboratories. Using previous published data of the same oral pathology laboratory (17), prevalence of PA could be estimated in less than 1% of all periapical lesions submitted to histological examination in our series. More likely, authors have characterized PA when sulfur granules with the Splendore-Hoeppli phenomenon are present, which consists in eosinophilic material around filamentous gram-positive colony-forming aggregates surrounded by inflammatory cells, probably composed of antigen-antibody complex, tissue debris and fibrin.…”

“…Hasil yang tidak jauh berbeda dengan penelitian yang dilakukan sebelumnya menunjukan bahwa daerah yang paling sering terjadi lesi periapikal adalah anterior rahang atas dan posterior rahang bawah. 6,9,16,17 Lesi periapikal pada daerah anterior maksila yang predominan menurut Berlinck & Monnerat pada tahun 2015 terjadi karena morfologi serta lokasi dan tingginya insidensi trauma sehingga mengarah pada resiko nekrosis pulpa yang lebih tinggi daripada regio posterior. 9,17 Posterior rahang bawah menjadi lokasi terbanyak kasus lesi periapikal karena gigi posterior memiliki permukaan oklusal yang berbeda, dimana gigi posterior memiliki pit and fissure yang lebih dalam sehingga sisa makanan sulit untuk dibersihkan.…”
