Recurrent peripheral ameloblastoma in an elderly patient: A case report.

Objective: To report a case of recurrent peripheral ameloblastoma (PA) in an elderly patient.

Background: PA is a benign tumour that affects soft tissues of gingiva or edentulous alveolar areas, exhibiting histopathological characteristics of ameloblastoma.

Methods: A 79-year-old man showed a nodule in the edentulous right mandibular alveolar ridge diagnosed as recurrent PA.

Peripheral Calcifying Odontogenic Cyst: A rare case report.

The Calcifying Odontogenic Cyst (COC) is a simple cyst lined by ameloblastoma-like epithelium with ghost cells. The peripheral COC is a rare lesion and few reports have been published considering its clinical and histopathological features. This article aimed to report on a case of a peripheral COC, discussing its clinical, imaginological and histopathological features.

Hyaluronic acid on collagen membranes: An experimental study in rats.

Objective: The aim of this study was to evaluate the effect of hyaluronic acid (HA) in the structure and degradation patterns of BioGide and OsseoGuard™ collagen membranes. HA mediates inflammation and acts in cell migration, adhesion, and differentiation, benefitting tissue remodeling and vascularization. These are desirable effects in guided regeneration procedures, but it is still unknown whether HA alters the barrier properties of absorbable membranes.

Enamel Pearls Implications on Periodontal Disease.

Dental anatomy is quite complex and diverse factors must be taken into account in its analysis. Teeth with anatomical variations present an increase in the rate of severity periodontal tissue destruction and therefore a higher risk of developing periodontal disease. In this context, this paper reviews the literature regarding enamel pearls and their implications in the development of severe localized periodontal disease as well as in the prognosis of periodontal therapy.
