Several guidelines for dental practice have been published by associations and regulatory boards since the beginning of pandemic. Initially, all non-emergency treatment were suspended. Healthcare personnel around world are gradually expanding back to elective procedures. International updated recommendations alert that professionals must maintain regular observation local health department repo...

Cementum was first demonstrated by microscopy, about 180 years ago. Since then the biology of cementum has been investigated by the most advanced techniques and equipment at that time in various fields of dental sciences. A great deal of data on cementum histology have been accumulated. These data have been obtained from not only human, but also non-human animals, in particular, rodents such as...

In epidemiological research the focus is on the occurrence, causes, and modifying factors of diseases and thereby their prevention. During the last decades, the epidemiology of dental caries has not dealt with the prevalence of the disease, but is measuring the past and present caries experience in terms of past and present treatment need, which does not follow the practices in epidemiology. Th...

BACKGROUND Accidental ingestion of medium-to-large instruments is relatively uncommon during dental treatment but can be potentially dangerous. A case of BiTine ring ingestion is presented with a note on inefficient ring separation forceps. CASE DESCRIPTION A 28-year-old male patient accidentally ingested the BiTine ring (2 cm diameter, 0.5 cm outward projections) while it was being applied t...

We developed a novel bioluminescent assay for detection of pyrophosphate in polymerase chain reaction (PCR) product. The principle of this method is as follows: pyrophosphate released by PCR is converted to adenosine 5'-triphosphate (ATP) by pyruvate phosphate dikinase in the presence of the substrate pyruvate phosphate and the coenzyme adenosine 5'-monophosphate; subsequently, ATP concentratio...

Oral malodor, also known as halitosis or bad breath, is a common problem worldwide and is associated with social embarrassment, anxiety and psychological depression [1]. Therefore, oral malodor has a negative impact on quality of life. Oral malodor is reported to be the third most frequent reason for people to seek dental care, behind dental caries and periodontal diseases [2]. The prevalence o...

The Electronic Patient Record (EPR) or "computer-based medical record" is defined by the Patient Record Institute as "a repository for patient information with one health-care enterprise that is supported by digital computer input and integrated with other information sources." The information technology revolution coupled with everyday use of computers in clinical dentistry has created new dem...

The purpose of this study was to study the absorbed dose in mouth due to scattering in teeth in dental radiography using the monte carlo simulation. The Electron Gamma Shower (EGS-4) system of computer codes was used, which is a general purpose package for Monte Carlo simulation of the coupled transport of electrons and photons in an arbitrary geometry for particles with energies above a few ke...

This paper proposes a methodological framework for the research of ergonomic risk factors in dentistry, since this is profession with very specific and complex challenges. When analyzing dental practice, three separate entities should be taken into account: dentist, as central figure office; office equipment, which includes all instruments devices, chair dentist stool; office, including workpla...
