Antibiotic prophylaxis is recommended for invasive dental procedures that involve the manipulation of gingival tissue or periapical region or perforation of the mucosa when performed on high-risk individuals. Australian guidelines have provided a list of dental procedures that are likely to cause a high incidence of bacteraemia that always require prophylaxis. These are as follows: Tooth extraction. Periodontal surgery, subgingival scaling and root planning. Replantation of avulsed teeth. Other surgical procedures such as implant placement or apicoectomy. Procedures that cause a moderate incidence of bacteraemia might be considered for prophylaxis if multiple procedures are being conducted, in cases where the procedure is prolonged, or in the setting of periodontal disease. Antibiotic prophylaxis is not recommended for procedures with a low possibility of bacteraemia such as: Local anaesthetic injections. Dental X-rays. Treatment of superficial caries. Orthodontic appliance placement a...

Antimicrobials used in dentistry Chemotherapy is the use of chemicals to destroy or inhibit the growth of cells. Two broad classes of chemotherapeutic agents are used in pharmacology:  antimicrobials and  anticancer drugs.  The basis of antimicrobial chemotherapy is a differential sensitivity of the patient and microbe cells to the action of the drug. The drug may affect a structural component of the target cell which is not found in the patient, for example, the bacterial cell wall. Alternatively, a chemotherapeutic agent may inhibit a metabolic pathway peculiar to the microbe cells, for example, synthesis of folate.

Can clothe masks be a substitute for N95 masks?      The researchers at the University of Chicago performed a study to check the  purification  ability of the cloth masks. They made masks by joining one layer of tightly woven cotton sheet 1  and two layers of polyester-spandex chiffon 2 , which is a fabric commonly used in evening gowns. These masks filtered out 80% to 90%  spray  particles ranging from 10 nanometres to 6 micrometres in diameter at normal human respiratory flow rate and volume.

Bio-Medical Waste (Management and Handling) Rules 2016 and further amendments in 2018 and 2019 have made enough provisions to handle all the biomedical wastes by any entity involved in anything related with health care provision. This includes, hospitals with only OPD facilities, hospitals with indoor facilities, blood donation camps, free health camps, medical services being provided in the field excluding the active war zones as well as the ships in the international water with Indian registration.   The categorization of all biomedical wastes into four color categories namely yellow, red, white, and blue made the segregation easy and practical. It does not specifically say anything about the rules and regulations to be followed  in reference to  COVID-19. But when, the proper biomedical waste management protocols, standard precauti...
