The Effect of St. John's Wort Oil (Hypericum Perforatum L.) in Knee Osteoarthritis: A Randomized Controlled and Qualitative Study.

Background: Reducing pain and improving physical function are critical in the treatment of osteoarthritis. Although individuals use St. John's Wort oil to relieve pain due to osteoarthritis, no scientific research has been found investigating its effectiveness.

A Comparison of four pulpotomy techniques in primary molars: a long-term follow-up.

The study evaluated the effects of formocresol (FC), ferric sulphate (FS), calcium hydroxide (Ca[OH](2)), and mineral trioxide aggregate (MTA) as pulp dressing agents in pulpotomized primary molars. Sixteen children each with at least four primary molars requiring pulpotomy were selected. Eighty selected teeth were divided into four groups and treated with one of the pulpotomy agent.

Ca(OH)2 pulpotomy in primary teeth. Part I: internal resorption as a complication following pulpotomy.

Objectives: The aim of this study was to analyze the outcomes of Ca(OH)(2) pulpotomies, to investigate the incidence of internal resorption following pulpotomy, and to investigate the relationship between internal resorption and physiological root resorption.

Study Design: Pulpotomies were performed in 84 primary molars. Teeth were grouped according to type of exposure (mechanical or carious) and according to whether or not physiological root resorption has started.

Internal resorption treated with mineral trioxide aggregate in a primary molar tooth: 18-month follow-up.

Mineral trioxide aggregate (MTA) repair of a mandibular second-primary molar tooth with an inflammatory resorptive defect in the coronal third of the root canal is reported in this case. After the root canals were obturated with zinc oxide eugenol sealer, MTA was applied to the resorption cavity. The coronal cavity was then restored with a stainless steel crown.
