Abstract

BackgroundOdontogenic cysts (OC) are the most frequent lesions of the jaws and their constant epidemiological update is necessary and indispensable. Therefore the principal objective of this report was To determine prevalence and clinical-demographical characteristics of OC in a Mexican sample.Material and Methods753 cases of OC coming from the archive of a head and neck histopathological teaching service, from January 2000 to December 2013, were included. OC cases were re-assessed according 2005 WHO classification. Chi square test was used to establish possible associations (p<0.05IC95%).ResultsFrom 753 OC, 369 were female and 384 male; 52.9% of them were in their 2nd- 4th decade of life. The most common location (41%) was the mandibular posterior area. Radicular cysts were more frequent in maxillary anterior zone of females (p 0.0002) at their fourth decade of life. Dentigerous cysts were more frequent in the mandibular posterior zone of males (p 0.0000) in their second decade of life. Six cases of periodontal lateral cyst; 4 cases of paradental cysts; 4 eruption cysts and 4 cases of adult gingival cyst, as well were identified.ConclusionsRadicular cyst and dentigerous cyst are the most prevalent odontogenic cyst in this Mexican sample. Due to their etiology, dental pulpar necrosis and impacted teeth, radicular cyst and dentigerous cyst could be prevenible. Therefore, it is necessary to establish preventive strategies to diminish dental decay and programs of prophylactic extractions of impacted teeth, to in consequence decrease the prevalence of odontogenic cysts. Key words:Cyst, dentigerous cyst, mexican, odontogenic cyst, radicular cyst.

Highlights

Odontogenic cysts (OC) are pathological cavities, lined with odontogenic epithelium, which appear in both jaws and sporadically in the oral soft tissues principally the gums [1]
Routine x-rays reveal suspicion of OC presence. Their genesis is closely related to dental ontogeny, 90% of them are formed from odontogenic epithelium or its embryonic remnants, in most cases, their etiology is still unknown [2,3,4,5]
In 2005, World Health Organization (WHO) reclassified odontogenic keratocyst as a tumor and renamed it keratocystic odontogenic tumor, while calcifying odontogenic cyst was classified as a tumor and was renamed Calcifying Cystic Odontogenic Tumor [1]

Summary

Introduction

Odontogenic cysts (OC) are pathological cavities, lined with odontogenic epithelium, which appear in both jaws and sporadically in the oral soft tissues principally the gums [1]. Routine x-rays reveal suspicion of OC presence Their genesis is closely related to dental ontogeny, 90% of them are formed from odontogenic epithelium or its embryonic remnants, in most cases, their etiology is still unknown [2,3,4,5]. A 14-year retrospective study was conducted at a maxillofacial and oral histopathological diagnosis teaching service with the main objective of to establish OC prevalence and to assess their demographical and clinical characteristics. Dentigerous cysts were more frequent in the mandibular posterior zone of males (p 0.0000) in their second decade of life. Conclusions: Radicular cyst and dentigerous cyst are the most prevalent odontogenic cyst in this Mexican sample Due to their etiology, dental pulpar necrosis and impacted teeth, radicular cyst and dentigerous cyst could be prevenible. It is necessary to establish preventive strategies to diminish dental decay and programs of prophylactic extractions of impacted teeth, to in consequence decrease the prevalence of odontogenic cysts
