Dental pulp elaborates both bone and dentin under pathological conditions such as tooth replantation/transplantation. This study aims to clarify the expression of granulocyte macrophage colony-stimulating factor (GM-CSF) and osteopontin (OPN) in the process of reparative dentin formation by allogenic tooth transplantation using in situ hybridization for OPN and immunohistochemistry for GM-CSF a...

When a dentist prepares a vital tooth, it is very important to know the distance between the prepared surface and the pulp chamber wall, and now we have developed ultrasonic diagnostic equipment which can indicate the nearness of these two boundaries by measuring the thickness of the remaining dentin. This equipment can be used to measure the thickness of the remaining dentin between the prepar...

The aim of the present in vitro study was to evaluate the temperature variation inside the pulp chamber during light-activation of the adhesive and resin composite layers with different light sources. Cavities measuring 8x10 mm were prepared on the buccal surface of bovine incisors, leaving a remaining dentin thickness of 1 mm. Specimens were placed in a 37±1 °C water bath to standardize the te...

Extracted human teeth are used in many preclinical courses. While there has been no report of disease transmission with extracted teeth, sterilization of teeth used in the teaching laboratory should be a concern. The purpose of this study was to determine the effectiveness of different sterilization/disinfection methods of extracted human teeth using Bacillus stearothermophilus, a bacteria resi...

Enamel anomalies – amelogenesis imperfecta, 1: 14000, several types with different heredity. Most frequent type is AD with hypomineralisation. Enamel matrix is normaly created, but the mineralisation is insufficient. The enamel is soft,peels off. Teeth are yellowbrown. Open bite is common. Reduction of pulp chamber occurs relatively early, so the reconstruction with crowns could be provided bef...
