Abstract
Introduction: the tooth formation is given by an embryological process called odontogenesis.
This process is carried out in two phases: morphogenesis and histogenesis. Both phases occur
continuously and the formation of the coronary development occurs equally in stages: bud or bud
stage, cap stage, bell stage and follicular stage, with their theories, chronology and determined
eruption sequence. If there is a delay greater than six months, it should be investigated whether
there is agenesis or if the tooth is included, which is the reason for our interest. The mandibular
third molars present a greater frequency of inclusion, followed by the maxillary third molars and
the maxillary canines. The early detection of radiological changes (pericoronary caps greater than
2.5mm) that occur in the pericoronary cap of the included teeth and the histopathological
differentiation of these caps is something that is not done frequently. These included tooth
pericoronary caps have pluripotential stem cells with the ability to differentiate and whose
differentiation could progress to tumor lesions (formation of dentigerous cysts, odontogenic
keratocyst, and ameloblastoma, among others).
Objective. To evaluate scientific literature about dentigerous cyst and ameloblastoma as the most
frequent pericoronary pathologies in dental practice.
Methods:A narrative literature review was performed, for this purpose the following
bibliographic databases were chosen as documentary sources: Pubmed, Scopus and Bireme.
Likewise, medical journals and articles from specialized journals accessible and known by the
authors of the present study were evaluated.
Results. Considering that the main objective of this study is to evaluate scientific literature about
dentigerous cyst and ameloblastoma as the most frequent pericoronary pathologies in dental
practice, 16 studies were analyzed in which it was confirmed that dentigerous cyst and
ameloblastoma are in this order the most frequent pathologies detected with respect to the groups
in which they are classified by the OMS as tumors and cysts. The age range in which the
dentigerous cyst is most present is between 20 and 30 years old, it predominates in the female sex
with 57% and almost unanimously in this table is evident that the anatomical region where the
cyst is most frequently observed is in the posterior mandibular area in 86% of cases,
radiographically the cyst is seen as radiolucent areas greater than 2 mm associated with included
third molars, and histologically they referenced stratified squamous epithelium in 11.5%, most of
The studies analyzed did not include a histological report. Respect to ameloblastoma, we can
conclude that it occurs more frequently between 15 to 30 years of age, almost unanimously, all
the articles agree that the male gender is the gender in which this pathology, appear the most,
associated with the mandibular body in higher percentage and only 37 cases are referenced to
included teeth, however 73% of the cases studied report the presence of a uniquistic image at the
radiographic level, and the anatomical area where this pathology is greatest is the body and
mandibular branch 67% Histologically 60% is associated with the plexiform type, which
according to the classification would be the uniquistic Type III. Conclusion. It is of great importance to carry out a good histopathological analysis of the tissues
originating from the dentigerous cyst, since cellular changes can occur in some areas of the cystic
wall, which must be considered for their respective evaluation and analysis. The complete
surgical removal of the dentigerous cyst aims to eliminate its recurrence and the possible
formation of pathologies with more aggressive behavior. The Ameloblastoma being a slow
growing lesion that is usually diagnosed by chance findings at the radiographic level, it is vitally
important to provide all the information to the patient regarding its management, due to its
aggressive behavior, it can cause large dental losses.
