There are about 165 dentistry-related journals in Japan. Almost all are Japanese-language journals. Articles or information in those journals are hardly disseminated outside Japan. Authors of review articles in Japanese Dental Science Review are not only Japanese, but also world-famous experts. Topics include the current state of knowledge or practice, recent advances, summaries and analyses of the consensus view on controversial issues, and Japanese researchers’ or clinicians’ viewpoints. The journal includes vivid information about studies conducted in the Japanese dental community. The numbers of downloads of articles from the journal have increased

every year. selleck products They have been downloaded in over 90 countries. Recently, we have started opening a wider door for submissions from researchers and clinicians all over the world to invigorate a forum of exchanging high quality basic, translational, and clinical

science. We welcome high-quality review articles from all over the globe. “
“The temporomandibular joint (TMJ) is the joint between the base of the skull and the lower jaw. Temporomandibular disorders (TMDs) are a group of disorders with symptoms that include pain, clicking, and restricted opening Venetoclax molecular weight of the jaw. Prevalence studies have reported that approx. 75% of the population has at least one of the signs of TMD (e.g., abnormal jaw movement, joint noises, tenderness on palpation) and that approx.

33% of the population has at least one TMD symptom; 3.6–7% of the population has sought treatment for severe TMD symptoms [1], [2], [3], [4] and [5]. Regarding the treatment of TMDs, a bibliographic search of databases can retrieve some systematic review articles as well as quite a few original research articles. However, few qualitative clinical guidelines for TMDs have been identified [6]. The creation of clinical guidelines for the treatment of TMDs is part of the mission of the Japanese Society for the Temporomandibular Joint. The first edition of the Society’s evidence-based clinical practice guidelines has been published and posted on the Society’s website [7], [8] and [9]. Clinical practice guidelines have been developed around the world in line with the principle 6-phosphogluconolactonase of evidence-based medicine (EBM) by the GRADE (grading of recommendations assessment, development and evaluation) approach produced by the GRADE working group [10], [11] and [12]. However, the GRADE approach is hardly used in Japan. The development of the guidelines for TMDs was based on a process of trial and error during the information-gathering period that was conducted in accord with the GRADE approach. However, there are only a few key clinical questions for TMDs in the guidelines, and three years have passed since the first guidelines were created. The need for more complete clinical practice guidelines regarding TMDs is clear.
