A severe public health crisis has been declared worldwide since coronavirus disease 2019 (COVID-19) was classified as a pandemic of acute respiratory infectious disease by the World Health Organisation (WHO). China has taken strict measures to curb the spread of the disease to save lives, and has managed to control the outbreak. ⋯ Nosocomial infection prevention and control concepts and measures relating to dental diagnosis and treatment are critically checked in the hospital. Our experiences in handling this situation are shared here and may have wide-ranging implications for infection prevention and control (IPC) for COVID-19 in dental practices worldwide.

The repair of large bone defects remains a huge challenge for bone regenerative medicine. To meet this challenge, a number of bone substitutes have been developed over recent years to overcome the drawbacks of traditional autograft and allograft therapies. Thus, the improvement of the osteoinductive ability of these substitutes has become a major focus for research in the field of bone tissue engineering. ⋯ Moreover, it is well documented that ions released from these substitutes such as magnesium, zinc, and strontium can increase the osteogenic and angiogenic properties of bone repair scaffolds. However, the mechanisms of action of these ions on cellular bioactivity are currently unclear. Therefore, in the present article, we highlight the recent use of bioactive ions in bone tissue engineering and discuss the effects of these ions on osteogenesis and neovascularisation.

To investigate the association between the analgesic effect of non-steroidal antiinflammatory drugs (NSAIDs) and sodium channel 1.7 (Nav1.7) expression in the trigeminal ganglion (TG). ⋯ Attenuation of hyperalgesia of inflamed TMJ by NSAIDs might be associated with their role in blocking upregulation of trigeminal ganglionic Nav1.7.

Randomized Controlled Trial Comparative Study
Mineral trioxide aggregate versus calcium hydroxide for pulpotomy in primary molars.
To compare the effects of mineral trioxide aggregate (MTA) and calcium hydroxide (CH) for pulpotomy in primary molars. ⋯ MTA was more successful than CH for pulpotomies in primary molar teeth, and may be a suitable replacement for CH in primary molar pulpotomies.

To evaluate the level of psychosocial difficulties in patients with temporomandibular disorders (TMD) by using the Symptom Checklist 90 revised (SCL-90-R), and determine whether there is an association between psychosocial status and chronic pain severity. ⋯ The GCP severity is a suitable tool to assess the psychosocial and physical status of TMD chronic pain. Some TMD patients have psychological problems and symptoms of psychopathology, especially those with high disability. Physicians should keep this possibility in mind when treating patients with TMD chronic pain.
