Time Course of Potassium Nitrate Penetration into the Pulp Cavity and the Effect of Penetration Levels on Tooth Whitening Efficacy.

Numai utilizatorii înregistrați pot traduce articole

To establish time-course of potassium nitrate (PN) penetration into the pulp cavity, and determine whether PN pretreatment would affect whitening efficacy. Extracted teeth (n = 100) were randomized into five groups of 20 specimens each. Relief ACP (Philips Oral Healthcare, Los Angeles, CA, USA) was

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND There is a range of treatment options for the management of the pulp in extensively decayed teeth. These include direct and indirect pulp capping, pulpotomy or pulpectomy. If the tooth is symptomatic or if there are periapical bone changes, then endodontic treatment is required. However,

The effect of whitening agents on caries susceptibility of human enamel.

Numai utilizatorii înregistrați pot traduce articole

To determine effectiveness of indirect pulp capping with 5% potassium nitrate in polycarboxylate cement for biological treatment of reversible pulpitis, a clinical study of 232 teeth with active caries lesions from 205 healthy patients aged from 16 to 40 years was performed. They were divided into 2

A new model for demonstrating enamel protection benefits relative to acid challenge.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE To determine the applicability of a modified US FDA Caries Monograph test method for measuring the protective benefits of fluoride (F) against erosive, dietary acids. METHODS Acid-challenged teeth were treated in two studies with a dentifrice, rinsed, and then re-challenged in a series of

Properties of a new mouthrinse for patients receiving radiation therapy.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Patients receiving radiation therapy due to oral cancer develop complications such as hyposalivation, mucositis, oral infections, dental hypersensitivity and caries. Mouthrinses can alleviate some of these problems. OBJECTIVE To investigate the in vitro antimicrobial properties and
