ObjectiveHydroxyl (OH-) and calcium (Ca++) ion release was evaluated
in six materials: G1) Sealer 26, G2) White mineral trioxide aggregate (MTA), G3)
epiphany, G4) epiphany + 10% calcium hydroxide (CH), G5) epiphany + 20% CH, and
G6) zinc oxide and eugenol.Material and MethodsSpecimens were placed in polyethylene tubes and immersed in distilled water. After
3, 6, 12, 24, and 48 h, 7, 14, and 28 days, the water was assessed for pH with a
pH meter and for Ca++ release by atomic absorption
spectrophotometry.ResultsG1, G2, G4, and G5 had the highest pH until 14 days (p<0.05). G1 presented
the highest Ca++ release until 6 h, and G4 and G5, from 12 h through 14
days. Ca++ release was greater for G1 and G2 at 28 days. G6 released
the least Ca++.ConclusionMTA, Sealer 26, epiphany, and epiphany + CH release OH - and
Ca++ ions. Epiphany + CH may be an alternative as retrofilling
material.
Aims: The aim of this study is to describe the surgical and prosthetic approaches of oral rehabilitation of a partially edentulous patient with a vertical maxillary excess with excessive gingival display when smiling. Presentation of Case: A 40-year-old female patient complaining of cosmetic dental problems reported to the School of Dentistry at Franca University (UNIFRAN). After a clinical examination and radiographic imaging, it was determined that the patient was partially edentulous with vertical maxillary excess with excessive gingival display when smiling. A diagnostic wax-up was performed to determine the ideal position of the anterior teeth in relation to proper oral posture at rest, to the Case Study
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
