Perceived oral health in patients after bariatric surgery using oral health-related quality of life measures.

Obesity is an increasing problem of the 21st century. A frequent intervention is bariatric surgery. The impact of bariatric surgery on oral health is largely unknown.

Ozone Treatment on Dentin Hypersensitivity Surfaces - A Pilot Study.

Background: Dentin hypersensitivity (DH) is a frequent condition in adults and difficult to treat. The aim of this single-blind, randomised controlled clinical trial was to investigate immediate and long-term effect of ozone treatment (Prozone, W&H NORDIC AB) for 12 seconds on hypersensitive teeth compared to placebo treatment, using a split-mouth design.

Methods: 26 patients (12 M, 14 F, mean age 44+ 2) were included in the study having at least two teeth with confirmed DH in different quadrants of the dentition (each subject had one test and one control tooth).

Treatment of deep caries lesions in adults: randomized clinical trials comparing stepwise vs. direct complete excavation, and direct pulp capping vs. partial pulpotomy.

Less invasive excavation methods have been suggested for deep caries lesions. We tested the effects of stepwise vs. direct complete excavation, 1 yr after the procedure had been carried out, in 314 adults (from six centres) who had received treatment of a tooth with deep caries.
