ABSTRACT
The purpose of this study is to analyze the literature of the paradental cyst,
presenting a detailed review in relation to the etiology, clinic, radiographic
characteristic, differential diagnostic, histopathological features, treatment and
prognostic. The study defines the paradental cyst as odontogenic inflammatory origin
mainly occurring in the vestibular region and or distal, rarely in the mesial region of
the lower vital molar. The lesion can be extended for periapical region, provided that
the bigger frequency is the cases that appear in the third lower molar partially
outbroken and impelled, with the history of recurrent pericoronaritis and absence of
generalized periodontal illness. The lesion can be presented as a subclinical infection
only confirmed histological, but the history of pericoronaritis and or presence of
signals and inflammatory symptoms are common. The radiographic characteristics
show small dependent variations of the localization of the lesion in the third lower
molar, and when associated with the first lower molar is common to find ossifying
periostitis. The mandibular infected buccal cyst can be considered a variant but not a
separate pathological entity of the paradental. The study suggests that some
paradental cysts have been characterized as other denominations or even with
incorrect diagnosis. The epithelial origin of this cyst isn’t completely clarified yet,
moreover it foments other quarrels. Several approaches are being verified regarding
to the treatment and the maintenance of the involved tooth and others with the
exodontics of the involved dental element presenting changeable justifications
related to the localization and the distinguishing diagnosis. The study concludes that
the acquirements of the physiopathology differential diagnosis of the lesion,
independent of its nomenclature, is primordial, through clinical and radiographic
characteristics to obtain a correct diagnosis and consequently the most adequate
and conservative treatment possible.
