“…OKC and UA are more aggressive lesions with high rates of recurrence. DC is less aggressive and deserves special attention because of its possible transformation into ameloblastoma (Bhushan, Rao, Navata, & Kumar, 2014). The AgNOR's and Ki-67 counting have been useful for evaluating the aggressive behavior of OKC, DC, and UA (Ananthaneni, Udayashankar, Guduru, & Ramprasad, 2014;Jaafari-ashkavandi et al, 2015).…”

The purpose of this study was to evaluate the metabolism and epithelial cell proliferation of odontogenic keratocyst (OKC), dentigerous cyst (DC), and unicystic ameloblastoma (UA) by quantifying the nucleolar organizing regions (AgNORs) and Ki-67 protein immunoexpression. Forty-eight cases (16 OKC, 16 DC, and 16 UA) were evaluated retrospectively. The metabolism and epithelial cell proliferation was measured by the Ki-67 positive cell percentage index and by the mean AgNOR count in each group. The Ki-67 and AgNOR counts were significantly higher in OKC comparing to the DC and UA (p < .001). Ki-67 positive cells were observed higher in suprabasal cell layers of OKC with uniform distribution, a few of them were predominantly observed in basal cell layer in DC and UA. The AgNOR count was significantly higher in the OKC basal cell layers and observed throughout the lining epithelium of DC and UA. Ki-67 and AgNOR reinforced the aggressive character of OKC, presenting high metabolism and cellular proliferation compared to DC and UA, possibly due to its more aggressive clinical behavior and high recurrence rate.Research Highlights 1. We evidence higher metabolism and epithelial cell proliferation in OKC when compared to UA and DC, supporting its aggressive aspect and its high rate of recurrence. OKC had intense and predominant labeling ofKi-67 on the suprabasal layer unlike UA and DC. K E Y W O R D S cell proliferation, metabolism, odontogenic cyst, impacted tooth, odontogenic tumors

“…They usually involve mandibular third molars, maxillary canines, maxillary third molars, mandibular premolars, as well as supernumerary teeth, such as mesiodens [ 1 , 3 ]. Despite being considered benign lesions, the literature reports examples of neoplastic alterations in the tissue of dentigerous cysts, leading to ameloblastoma development [ 4 ].…”

This study presents a case report of an inflammatory dentigerous cyst of tooth #35, associated with its previously endodontically treated deciduous predecessor. Cystic lesion growth caused impaction of the second premolar, displacing it closer to the lower border of the mandible. The lesion represents a typical dentigerous cyst that possibly arises in association with periapical inflammation of a deciduous molar involving the follicle of the premolars. This report highlights the inflammatory etiology of dentigerous cysts, which mainly occur in mixed dentition. A 12-year-old patient was referred to Oral Surgery Department regarding a sizeable radiolucent lesion in the unerupted mandibular second premolar region, detected on an Orthopantomagram (OPG) X-ray. A non-vital primary predecessor had been endodontically treated at least one year before an examination, with a control OPG X-ray showing no signs of pathology at the time. The patient did not report any symptoms. Clinical examination revealed an egg-like tumefaction of the alveolar bone in the left premolar region of the mandible. Cone-beam computed tomography analysis showed a sizeable translucent lesion surrounding the crown of the impacted tooth. The lesion was enucleated in its entirety, along with the impacted premolar, under local anesthesia. Clinical findings combined with radiographic and microscopic examinations confirmed the diagnosis of an inflammatory dentigerous cyst. The seventeen month follow-up revealed good bone healing. This case presented a rare complication of endodontic treatment of deciduous teeth and informed on possible complications of endodontic therapy in deciduous teeth, emphasizing the importance of early diagnosis of cysts in preventing extraction of permanent teeth.

Unicystic ameloblastoma is a benign, locally invasive odontogenic neoplasm of young age which can develop during the stage of tooth formation and hence its early inception and vast proliferation is not uncommon in this age group, due to which it can grow into a huge lesion causing significant morbidity. Conservative surgical management may be a viable option to reduce morbidity and increase the probability of uneventful secondary healing and bone regeneration in the younger population.
