Evaluation of cysts and odontogenic tumors over a period of 8 years in a reference medical hospital in Brazil

Abstract

Objective: This study aimed to evaluate the relative prevalence, demographic distribution and clinical-pathological characteristics of the maxillary odontogenics cysts and tumors of the jaws in a pathology laboratory located in a university hospital in Northeastern Brazil. Methods: An observational and retrospective study was carried out, in which information was collected on histopathological diagnosis, age, gender and location of the lesion of patients who had been diagnosed with odontogenic cysts or odontogenic tumors between 2013 and 2020. Results: Among the 546 specimens, 57 were odontogenic cysts and 41 were odontogenic tumors. The most frequent odontogenic cysts were the odontogenic keratocyst 21 (21.4%) and the root cyst 19 (19.4%). The most frequent odontogenic tumors were ameloblastoma 27 (27.6%) and odontoma 6 (6.1%). Conclusion: The data found in this study are possibly associated with the service assistance profile.

“…According to the age of patients, it differs from 6 years old to 80 years old, with a mean of 32.4 ± 16.4. The present study revealed that the odontogenic cysts mainly occurred in the 2 nd and the 3 rd decades of life, which is in line with studies from Mexican [9], Brazilian [12], Indian [10], and Iranian populations [14]. Furthermore, of the 368 odontogenic cyst patients, 222 (60.33%) were males and 146 (39.67%) were females.…”

“…Furthermore, of the 368 odontogenic cyst patients, 222 (60.33%) were males and 146 (39.67%) were females. With a male-to-female ratio of about 1.52:1 (Tables 2 and 3), which was consistent with research performed in other countries, including Portugal, Brazil, Mexico, Italy, India, Kenya, Greece, Turkey, Italy, and Iran (ranging between 50.9 % and 64.4 %) [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. In contrast, female predominance was significant in the Brazilian population [26] and among Indonesians [24].…”

“…Therefore, the most common type of odontogenic cyst in this study was radicular cysts. Similar results were found in most of the previous studies of different countries [18][19][20][21][22][23][24][25][26], while odontogenic keratocyst was the most predominant in the Brazil study [12]. Furthermore, Butt et al reported that dentigerous cysts (31%) were the most common type of odontogenic cysts, followed by radicular cysts (22%) in Kenya [17] with slight differences.…”

“…The frequency of odontogenic cysts was 10.8% of total biopsied specimens. When the results of the present study were compared with the results of the other studies from different countries (Table 4), it was found that the studies from Mexico [9], India [10], Brazil [11,12], Greece [13], and Iran [14,15] reported similar frequencies ranging between 6.8% and 17.7%. Studies from Turkey [16], Brazil [11], and Kenya [17] reported the higher frequencies for odontogenic cysts (Table 1).…”

“…It is slow-growing and asymptomatic, and its principal location is in the jaw. AB constitutes 11% of odontogenic tumors 5 , and it is more common in men than in women 6 . Clinically, it presents as a swelling with the expansion of bone cortices, sometimes accompanied by dental mobility and displacement 7,8 .…”
