12. DENTAL AEROSOLIZATION
13. Dental procedures create particles ofdroplets and aerosol withCOVID-19 •Firstly,
many dental procedures, such as those including the use of high-speed turbines and running water, release a large number of particles of droplets and aerosols mixed with the patient’s saliva to the air.
INCUBATION PERIOD of COVID-19 has been estimated at 5 to 6 d on average. -The ASSYMPTOMATIC INCUBATION PERIOD for individuals infected with 2019-n Cov has been reported to be 1-14 days,
Very high High Medium Low risk Healthcare workers, laboratory personnel, morgue workers performing autopsies Medical transport workers,
Clinicalmanifestations PANDEMIC (COVID-19) Cough Fever Shortness Of Breath Sore Throat ● Atypical symptoms, such as muscle pain, confusion, headache ● Fatigue ● Diarrhoea and vomiting
older age and the existence of underlying co- morbidities (e.g., diabetes, hypertension, and cardiovascular disease) were associated with poorer prognosis
LaboratoryDiagnosis
All symptomatic contacts of laboratory confirmed cases  All symptomatic health care workers  All patients with Severe Acute Respiratory Illness  Asymptomatic direct and high-risk contacts of a confirmed case should be tested once between day 5 and day 14 of coming in his/her contact.
Throat and nasal swab Preferred sample • Nasopharyngeal swab, • Endotracheal aspirateAlternate: Samplecollection
22. Lower respiratory tract Bronchoalveolar lavage, tracheal aspirate, sputum Collect 2-3 mL into a sterile, leak-proof, screw-cap sputum collection cup or sterile dry container. Upper respiratory tract Nasopharyngeal swab / oropharyngeal swab
wear appropriate PPE with latex free purple nitrile gloves while collecting
Tilt patient’s head back 70 degrees.  Rub swab over both tonsillar pillars and posterior oropharynx Avoid touching the tongue, teeth, and gums.

Reverse transcriptase polymerase chain reaction (RT-PCR) RNA must first be converted to DNA using an enzyme called reverse transcriptase.

droplet and aerosol transmission are significant risks in the dental practice setting.
Step 1: TELEPHONIC PRESCREENING PROTOCOL • Fix appointments through phone only & Discourage Walk-in Patients
Step 2: RECEPTION/ WAITING AREA PROTOCOL • Receptionist / Staff : One Person • Discourage footwear within clinic interiors/ provide foot cover • Record patient temperature using Digital Non-contact Infrared Thermometer • Mandatory use of Alcohol Based Hand Rub (ABHR) & provide Mask for everyone • Seating arrangement with minimum 3 feet Physical Distancing
Step 3: DENTAL OPERATORY PROTOCOL • Keep the clinical operatory clutter-free • Improve air circulation and avoid air-conditioners • 0.01% NaOCl for disinfection of dental water lines
Step 4 Pre-Procedural Mouth rinse: 1% Hydrogen peroxide or 0.2% Povidone-iodine : 1 min
Step 5: PATIENT DISCHARGE • Patient advised to re-mask and proceed to reception area • Hand Hygiene • Electronic Treatment records only
