Glob Med Genet 2021 Jun 15;8(2):41-50. Epub 2021 Mar 15.

Department of Oral Pathology, Tirumala Institute of Dental Sciences, Nizamabad, Telangana, India.

Bone is a specialized form of connective tissue, which is mineralized and made up of approximately 28% type I collagen and 5% noncollagenous matrix proteins. The properties of bone are very remarkable, because it is a dynamic tissue, undergoing constant renewal in response to mechanical, nutritional, and hormonal influences. In 1978, "The International Nomenclature of Constitutional Diseases of Bone" divided bone disorders into two broad groups: osteochondrodysplasias and dysostoses. Read More

Salivette, a relevant saliva sampling device for SARS-CoV-2 detection.

J Oral Microbiol 2021 Apr 30;13(1):1920226. Epub 2021 Apr 30.

Unité Parasitologie Et Entomologie, Département Microbiologie Et Maladies Infectieuses, Institut De Recherche Biomédicale Des Armées, Marseille, France.

The gold standard for COVID-19 diagnosis relies on quantitative reverse-transcriptase polymerase-chain reaction (RT-qPCR) from nasopharyngeal swab (NPS) specimens, but NPSs present several limitations. The simplicity, low invasive and possibility of self-collection of saliva imposed these specimens as a relevant alternative for SARS-CoV-2 detection. However, the discrepancy of saliva test results compared to NPSs made of its use controversial. Read More

Sci Rep 2021 May 13;11(1):10246. Epub 2021 May 13.

Department of Oral Medicine and Oral Diagnosis, School of Dentistry and Dental Research Institute, Seoul National University, #101, Daehak-ro, Jongro-gu, Seoul, 03080, Korea.

Orthopantomogram (OPG) is important for primary diagnosis of temporomandibular joint osteoarthritis (TMJOA), because of cost and the radiation associated with computed tomograms (CT). The aims of this study were to develop an artificial intelligence (AI) model and compare its TMJOA diagnostic performance from OPGs with that of an oromaxillofacial radiology (OMFR) expert. An AI model was developed using Karas' ResNet model and trained to classify images into three categories: normal, indeterminate OA, and OA. Read More

Osteocytes as main responders to low-intensity pulsed ultrasound treatment during fracture healing.

Sci Rep 2021 May 13;11(1):10298. Epub 2021 May 13.

Oral Biochemistry and Molecular Biology, Graduate School of Dental Medicine, Hokkaido University, Kita 13, Nishi 7, Kita-ku, Sapporo, 060-8586, Japan.

Ultrasound stimulation is a type of mechanical stress, and low-intensity pulsed ultrasound (LIPUS) devices have been used clinically to promote fracture healing. However, it remains unclear which skeletal cells, in particular osteocytes or osteoblasts, primarily respond to LIPUS stimulation and how they contribute to fracture healing. To examine this, we utilized medaka, whose bone lacks osteocytes, and zebrafish, whose bone has osteocytes, as in vivo models. Read More
