Vital pulp therapy (VPT) of permanent mature teeth is continuously ascertaining to be a more reliable endodontic treatment. The purpose of this case report was to describe successful VPT of a mature mandibular left first molar with concurrent hyperplastic pulpitis, internal root resorption and periradicular periodontitis in a 35-year-old male patient. After complete caries removal and access ca...

This study was performed to examine the success of a conservative cavity preparation using the principle of "sealing for prevention" rather than "extension for prevention." A total of 332 restorations were placed in 243 permanent molars in 114 children aged 6-14 with a mean age of 8 years. After 80 months, 104 restorations were examined for sealant retention, marginal staining, anatomic wear, m...

Background: There is little systematic research about the efficacy of multimedia-based system for learning in medical sciences. The purpose of this study was to evaluate the efficacy of an interactive multimedia courseware package to demonstrate access cavity preparation for undergraduate dental students in preclinical endodontics course and compare with tutorial method of education. Methods: T...

OBJECTIVES To quantify the temperature increments in a simulated dental pulp following irradiation with an Er:YAG laser, and to compare those increments when the laser is applied with and without water spray. METHODS Two cavities were prepared on either the buccal or lingual aspect of sound extracted teeth using the laser. One cavity was prepared with water spray, the other without and the or...

OBJECTIVE This study was conducted to analyze microleakage in Class V cavity preparation, using rewetting (or not) just after burr or Er:YAG laser preparation of enamel and dentin walls in permanent teeth. BACKGROUND DATA Several studies reported microleakage around composite restorations when cavity preparation was done or treated by Er:YAG laser. As the hybridized laser is removed when this...

The use of haptic devices in the medical field has become widespread in the last decade. In this study, a visio-haptic dental training system is developed using haptic and stereoscopic devices. Several advantages are offered by such a simulation system, including effective learning without any fear of making mistakes on a patient, possibility of repeating various dental operations, ease of eval...

Amelogenin is the major enamel matrix protein with key roles in amelogenesis. Although for many decades amelogenin was considered to be exclusively expressed by ameloblasts, more recent studies have shown that amelogenin is also expressed in other dental and no-dental cells. However, amelogenin expression in human tissues remains unclear. Here, we show that amelogenin protein is not only expres...

When I graduated from dental school in 1987, dental amalgam was essentially the only material available for the direct restoration of carious posterior teeth. Dentin bonding was in its first generation of technological development in restorative dentistry, and composite resin restoration of posterior teeth was carried out with caution by some dentists, but avoided by most. Even at that time, th...

Many new technologies with potential application to dentistry are on the horizon, including tissue engineering, gene and growth factor therapy, although there are a number of problems to overcome1 before these might be introduced clinically. However, the dentine-pulp complex has strong natural regenerative capacity and exploitation of these biological repair processes can allow current approach...
