It is generally accepted that a certain change occurs in teeth containing a vital pulp as a response to such injuries as caries, attrition and abrasion. In these cases dentinal tubules are filled with gaseous substances. In ground sections the groups of dentinal tubules, appearing black in transmitted light, have been named dead tracts by FisH[1-3]. However, there are few reports on the observa...

The need for simulation models to thoroughly test the inflammatory effects of dental materials and dentinogenic effects of specific signaling molecules has been well recognized in current dental research. The development of a model that simulates the transdentinal flow and the mass transfer mechanisms is of prime importance in terms of achieving the objectives of developing more effective treat...

This case report describes intratubular biomineralization in root canal, filled with calcium-enriched material after 8 years of clinical maintenance. The schematic findings of dentinal tubules were investigated with scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The root canal obturation material was closely adapted to root dentin surface, suggesting the possibilit...

Our teeth are constantly subjected to erosion caused by the action of food and drinks (1). These aggressions result in the exposure of dentinal tubules and the underlying nerves to the external environment. Consequently, external stimuli trigger the nerves causing a short and acute pain clinically defined as dental hypersensitivity (2). Individuals with this condition present tooth with open de...

According to FUJITA (1957) and TAKUMA (1960), the structure of the dentinal tubule wall in human dentin has been studied by KOLLIKER, NEUMANN, WALKHOFF, FLEISCHMANN, HANAZAWA, MEYER and ORBAN. Recently, TAKUMA and TSUCHIKURA (1950) found by means of the electron microscope that the dentinal tubules were lined with a hypercalcified area, and designated it as peritubular hypercalcified matrix. Th...

introduction: the aim of this trial was to compare clinical and radiographic success rates of direct pulp capping (dpc) using a novel biomaterial called calcium enriched mixture (cem) cement versus mineral trioxide aggregate (mta) in primary molar teeth. materials and methods: in this randomized clinical trial 42 deciduous molars in 21 patients who had at least two teeth requiring dpc, were tre...

INTRODUCTION This study analyzed the in vivo microbiological status of the root canal systems of mesial roots of mandibular molars with primary apical periodontitis after 1- or 2-visit endodontic treatment. METHODS Mesial root canals were instrumented by using either a combination of K3 and LightSpeed instruments (mesiobuccal canals) or the ProTaper system (mesiolingual canals), with 5% NaOCl...

introduction: dentin hypersensitivity (dh) is characterized by tooth pain arising from exposure of dental roots. in this study the efficiency of neodymium yttrium-aluminum-garnet (nd:yag) laser in association with graphite on dentinal surface changes as the alternative to the treatment of dh was evaluated. methods: sixteen noncarious human third molars were collected and sectioned into 5 parts ...
