ABSTRACT Introduction: Odontogenic cysts constitute a group of frequent intraosseous lesions characteristic in the maxillary bones and one ofthe main causes of the destruction of these bones. In Chile there are no retrospectivestudies of these lesions as a whole. Objective: The purpose,of this study is to determine the frequency of these lesions in so far as they were diagnosed,and registered in the Referral Institute for Oral Pathology (IREPO) of the,University of Chile in two age groups as well as to analyze and to compare the data obtained with the data published in previous studies. Material and Method: We studied,the records from IREPO oft he,University ofC hile for the period between,1976 and September, 2004; and we determined the frequency according to age, gender and site of each of these lesions. W e compare,two age groups: younger,than or equal to 15 years old and older than 15 years old. Those cases in which the information,did not suffice for the purposes of analysis were not considered. All the histological slides were reclassiffed according,to the diagnostic criteria included in the Histological Typification of the World Health Organization. Results: We found 2.944 odontogenic cysts (OC), of which 1.935 (65.7%) were inflammatory cysts and 1.009 were developmental cysts. Out of this total, there were 1.554 cysts (52.8%) in men and 1.390 (47.2%) in women. The most frequent cysts were 1.494 radicular cysts (50.7%), 546 dentigerous cysts (18.5%), 421 keratocysts (14.3%) and 328 resi- dual cysts (11.1%). These four varieties represent 94.7% of the OC , that is, 2789 cases. In the population younger than or equal to 15 years
Cumulative Annual
    • ...Some studies found that the maxilla was the most frequent anatomic site [3, 7, 9], whereas other authors reported that the mandible was the most prevalent site [6, 8]...
    • ...The maxilla was the anatomic site most often affected by odontogenic cysts in our study, which differs from findings by Meningaud et al. [6] and Koseoglu et al. [8], but is in agreement with other studies [3, 7, 9]. Although cysts show predilection for the maxilla, in four of the six cases diagnosed in our study, the mandible was the most prevalent site (Table 3)...
    • ...In our study, radicular cysts accounted for 72.5% (69.63% with the inclusion of OKC) of all cases, a higher percentage than those found by Jones et al. [2] (52.3%), Ochsenius et al. [3] (50.7%), Mosqueda-Taylor et al. [4] (39.9%), Ledesma-Montes et al. [5] (38.8%), Meningaud et al. [6] (53.5%), Bataineh et al. [7] (41.7%) and Koseoglu et al. [8] (59%), but lower than the percentages reported by Varinauskas et al. [9] (86.2%) and Franklin ...
    • ...According to the literature, the most frequently affected site is the anterior maxilla [2, 3, 5, 7, 8], which is in agreement with our findings but differs from those reported by Meningaud et al. [6], who reported that the mandible was more frequently affected...
    • ...The fact that the anterior maxilla is more often affected may be explained by esthetic factors, as patients may wish to preserve their anterior teeth even when endodontic treatment is not adequate [3]...
    • ...The third and fourth decades of life were the most frequent in our study (Table 4), in agreement with findings in the literature [2, 3, 5, 7, 8]...
    • ...The mandible was the bone most frequently affected in our study, and the posterior region was the most frequent site, followed by the anterior maxilla, which is in agreement with other studies [2, 3, 7, 8]. Such prevalence may be explained by the large number of impacted mandibular third morals and maxillary canines...
    • ...Most dentigerous cysts occurred in patients in the second decade of life in this study (Table 4), as well as in the studies conducted by Ochsenius et al. [3], Ledesma Montes et al. [5], Bataineh et al. [7] and Koseoglu et al. [8]...
    • ...Jones et al. [2] and Ochsenius et al. [3] found that residual cysts were most frequently found in the anterior maxilla...
    • ...The diagnosis of this pathology was more prevalent in patients over 80 years old (Table 4), whereas the third, fifth and sixth decades of life were found to be the most frequent in the studies by Ledesma-Montes et al. [5], Ochsenius et al. [3] and Bataineh et al. [7] The finding that patients with residual cysts are older than patients with radicular cysts may be explained by the fact that cystic lesions are located inside the maxilla, ...
    • ...This type of cysts was the fifth most frequent in this study and accounted for 0.58% of the cases (0.56% with the inclusion of OKC), a lower percentage than the one reported by Jones et al. [2] (5.6%), Ochsenius et al. [3] (3.8%), Mosqueda-Taylor et al. [4] (1.4%) and de Sousa...
    • ...A predilection for male sex [2‐4, 6, 7, 18] and the premolar region [3, 7, 19] is found in the literature...
    • ...With the inclusion of OKC, our results showed a greater prevalence of inflammatory cysts (74.3%), similar to the rates reported by Jones et al. [2] (62.28%), Ochsenius et al. [3] (65.7%), Meningaud et al. [6] (58.2%), Bataineh et al. [7] (61.4%) and Koseoglu et al. [8] (58.8%), whereas Ledesma-Montes et al. [5] and Mosqueda-Taylor et al. [4] found a greater frequency of developmental cysts...
