Clinical treatment of necrotizing ulcerative gingivitis: a case report with 10-year follow-up.

The aim of this case report is to describe the diagnosis and treatment of a patient with necrotizing ulcerative gingivitis. An 18-year-old man with no systemic problems reported with chief complaints of gingival bleeding during toothbrushing and spontaneous pain. Clinical examination revealed significant plaque accumulation on the surfaces of all teeth as well as papillary necrosis involving mainly the anterior teeth.

Effect of Different Doses of Synthetic Parathyroid Hormone (1-34) on Bone around Implants: a Preclinical Rat Model.

The aim of this study was to evaluate the effect of a lower dose of parathyroid hormone- PTH (1-34) on osteogenic potential of bone healing around titanium implants inserted into the tibia of rats. A blind parallel study was conducted in 45 adult male Wistar rats. Each rat received one titanium implant (4.

Enamel defects and tooth eruption disturbances in children with sickle cell anemia.

Sickle cell anemia, a genetic disease caused by a mutation in the beta-globin gene, can present oral manifestations such as delayed tooth eruption and hypomineralized enamel and dentin. The aim of the present study was to evaluate the prevalence and severity of developmental defects of enamel (DDE) and delayed tooth eruption in children with sickle cell anemia. The sample comprised 56 male and female children with sickle cell anemia aged 6 to 12 years and treated at the Hematology and Hemotherapy Center of Pernambuco, Brazil.

Maxillary sinus floor pneumatization and alveolar ridge resorption after tooth loss: a cross-sectional study.

This is a cross-sectional study that aimed to estimate maxillary sinus floor (MSF) pneumatization in single missing tooth of posterior maxilla, by using cone-beam computed tomography (CBCT). CBCT images were analyzed bilaterally and divided into 2 groups: edentulous site (EdS) - edentulous single region of upper second premolar, first or second molars; Tooth site (TS) - contralateral region homologous to the EdS region, with tooth present. Variables evaluated were: sinus height (SH), estimated sinus pneumatization (eSP: ∆ EdS - TS), healed ridge height (HR) and presence of localized sinus pneumatization (LSP) in molars teeth at TS.
