Premature exfoliation of primary or permanent teeth in children or adolescents is extremely rare and it can be a manifestation of an underlying systemic disease. This study aims to present the histological aspects associated with early tooth loss in a case of periodontal disease developed without local inflammation and with minimal periodontal pockets and attachment loss. The maxillary left second premolar was extracted together with a gingival collar attached to the root surface. The histological analysis recorded the resorption of the cementum in multiple areas of the entire root surface with the connective tissue of the desmodontium invading the lacunae defects. The connective tissue rich in cells occupied the periodontal ligamentar space and the resorptive areas. No inflammation was obvious in the periodontal ligament connective tissue. This report may warn clinicians about the possibility of the association of cemental abnormalities with early tooth loss.

Prozostrodontia is a clade of probainognathian cynodonts that exhibit several morphological innovations later inherited by mammals. The earliest representatives of this group have been found in the Upper Triassic deposits of southern Brazil. In this study, we report the discovery of a probainognathian cynodont from the Buriol site (São João do Polêsine, Rio Grande do Sul, Brazil), Hyperodapedon Assemblage Zone (Late Triassic).

The aim of this retrospective study was to compare the histomorphometry of post-extractive sites previously grafted with deproteinized bovine bone, with or without the association of a calcium sulphate preparation. The retrospective evaluation comprehended patients previously selected and treated for the extraction of one or more mono-radicular teeth, followed by an implant-prosthetic rehabilitation. Post-extractive sites had been randomly assigned to test or control group, respectively, if deproteinized bovine bone was used in association with a calcium sulphate preparation or alone.

Background/objectives: Oral frailty, first identified in Japan in 2014, refers to a state between healthy oral function and severe decline, marked by minor issues, such as tooth loss and chewing difficulties. The oral frailty five-item checklist (OF-5) enables non-dental professionals to evaluate oral frailty using five key indicators: remaining teeth count, chewing difficulties, swallowing difficulties, dry mouth, and articulatory oral skills. Limited studies exist.

Background Indirect pulp capping (IDPC) is a preferred treatment for pulp preservation in primary teeth. However, the survival rate of IDPC in primary teeth and impact factors is still equivocal.Aims To evaluate the survival rate of IDPC in primary teeth with a deep carious lesion approximating the pulp but without irreversible pulpitis or periapical disease.

Objective: Abaloparatide (ABL) is a synthetic parathyroid hormone-related protein analog developed as an anabolic drug to treat osteoporosis. ABL increases bone mineral density (BMD) of the long bones and spine; however, the influence of ABL on alveolar bone regeneration remains unknown. This study assessed the effects of systemic ABL administration on tooth extraction socket healing and dental implant osseointegration in a preclinical rodent model.
