With good oral hygiene maintenance, pericoronal
tissues would be easily maintained; however, the contact area between the second and third molars would remain relatively inaccessible with consequent long-term plaque accumulation.
In past, a pericoronal
radiolucency was considered as non pathologic if it was smaller than 2.5 mm in width.
Radiograficamente la lesion se presenta como un proceso osteolitico con localizacion pericoronal
, interradicular o periapical (9), en general muestra bordes bien definidos, en un patron uni o multilocular, siendo el de mayor ocurrencia el unilocular (1,3,4,6,13,15), este ultimo suele estar asociado con dientes retenidos de pacientes jovenes con una edad media de 22 anos, mientras que el tipo multilocular se encuentra en adultos con una edad media de 33 anos (16,17).

Tooth 3,3 presents a pericoronal
space of normal thickness, uni-radicular and an irregularly shaped radiopaque area placed in middle and upper thirds of mandibular body, between roots of 3,4 and 3,5 teeth, close to foramen mentale and apex of tooth 4,3, compatible with idiopathic osteosclerosis (yellow arrow) (Fig.
radiolucencies and the significance of early detection.
This classification added categories for gingival diseases, abscesses of the periodontium (gingival, periodontal, and pericoronal
abscesses), periodontitis associated with endodontic lesions, and developmental and acquired deformities and conditions (local factors related to teeth, mucogingival deformities, and occlusal trauma).
(26, 27) In 2001, Consolaro et al noted that the movement of teeth with incomplete root formation creates a decrease in root length by early apex closing--which depends on embryo maturation of papillary and pericoronal
tissue of dental follicle--and not by root resorption.
The association between the CEOT and the impacted tooth producing pericoronal
radiolucency can mimic dentigerous cysts.
They appear in children as pericoronal
sclerotic lesions with a thin radiolucent rim and are commonly associated with an impacted tooth.
DISCUSSION: Impacted mandibular third molar is one of the most common conditions which often necessitate its surgical removal for various reasons like pericoronitis, pericoronal
abscess, cyst, orthodontic treatment, involvement in fracture line and various tumors.
