Before restoring a tooth with composite, the area is etched. Accidental contamination occurs with saliva, Therefore
1) the area is re-etched before restoration
2) the area is air-dried using an air spray and continue with restoring
3) wipe the saliva with cotton and continue to restore.
4) add excess composie material and cure it
Etching of tooth surface with 37% phosphoric acid creates microporosities in the enamel and dentin.
After etching the surface energy of the enamel will increase. This will make it very sticky to any kind of contaminants. If salivary contamination will occur, the salivary proteins will precipitate in the microporosities. This will prevent the adequate penetration of the bonding agent, therby reducing the micotag formation. Hence, complete isolation is essential.

A patient comes complaining of a bad taste and bad smell from a newly fixed 3-unit fixed partial denture. Upon examination, bubbles are coming from one of the abutments when pressure is applied on it with a water spray. What is the likely reason?
1) Fractured joint.
2) Open margin.
3) Loose abutment.
4) Overcontoured restoration.
ADC Test Answer: 2
The presence of bubbles and bad taste/smell indicates potential leakage or movement at the margins of the restoration, suggesting an open margin that allows bacteria and fluids to enter, causing these symptoms.
Which of the following is NOT a protective component of saliva against dental
caries?

A progress note is used to record the patient's current condition, any changes observed since the last visit, the treatment provided during the appointment, and the dentist's observations and findings. It is an ongoing part of the patient's clinical record that helps track the patient's oral health over time.
Which immunoglobulin is present in periodontitis?
1) IgA
2) IgM
3) IgG
4) IgE
IgG, especially IgG2, is commonly found in the gingival tissues of patients with periodontitis, indicating an immune response to bacterial infection. IgG plays a key role in protecting periodontal tissue by neutralizing toxins and aiding the elimination of pathogens through mechanisms like phagocytosis. Higher levels of immunoglobulins, particularly IgG, are associated with an increased immune response in inflamed gingival tissues. Secretory IgA (sIgA) is the main immunoglobulin in secretions and acts as the first line of defense, preventing microbial adherence to the oral mucosa. IgM can also be detected, particularly in inflamed states.
What is the recommended position for a pregnant patient during oral surgery to avoid pressure on the inferior vena cava?
1) Supine position

What is the primary purpose of taking dental impressions?
1) To diagnose dental conditions
2) To create a mold for restorations or orthodontic appliances
3) To monitor teeth movement over time
4) To educate patients about oral hygiene
Dental impressions are taken to create a precise mold of a patient's teeth and surrounding structures. These molds are then used by dental laboratories to fabricate restorations like crowns, bridges, dentures, and orthodontic appliances that fit accurately in the patient's mouth. While impressions can indirectly help in diagnosis, their primary purpose is for the creation of these appliances.
