Study Notes

Anesthesia and Pain Management

Non-aerosol topical anesthetic may be applied by a dental assistant (DA) or registered dental assistant (RDA).
Topical anesthetics are primarily used for relief of pain and anxiety during procedures.
For infiltration anesthesia, topical anesthetic is applied in the muco/buccal fold over the apex area of operation.

Mouth Signs and Symptoms

A mobile tooth is considered a sign indicating potential dental issues.
Cheilitis refers to cracking at the corners of the mouth.
A hematoma is categorized as blood in the soft tissue.

Salivary Glands and Biopsy

The tab of tissue opposite the upper first molar is the opening to the parotid salivary gland.
Biopsy is the procedure of removing tissue for microscopic examination.

Orthodontics

Class I malocclusion involves normal positioning of posterior teeth with malpositioned anterior teeth.
Class II malocclusion features protruded posterior teeth in relation to the mandible.
Class III malocclusion is characterized by retruded posterior teeth in relation to the mandible.
Elastic orthodontic separators are placed by a DA and are not made using tie wires.
T-P springs serve as separators in orthodontic procedures.

Equipment and Measurements

A sickle scaler is a useful instrument for removing elastic separators.
An elastic separator must be left in place for 3-5 days and should be placed by a period of more than 8 hours.
The patient's overjet is defined as the horizontal distance maxillary teeth protrude beyond the mandible.

Vital Signs and Patient Preparation

Vital signs include blood pressure, pulse, temperature, and respiration rates.
Specific instructions should be given to patients prior to procedures, including avoiding food and liquids after topical fluoride application.

Temporary Restorations and Dressings

Temporary fillings must have sealed margins and appropriate contact points.
Temporary sedative dressings help protect the dentin and pulp and maintain tooth contact and occlusion.
A "pigtail" from a wire ligature should be cut to a length of approximately 3 mm and bent gingivally.

Tooth Anatomy and Preservation

Correctly placed temporary crowns should replicate the tooth's mesio-distal length and occlusal height.
Mottled enamel results from excessive fluoride in drinking water, while the ideal fluoride concentration in community water supplies is 1.0 ppm.

Dental Procedures and Patient Care

A correctly applied rubber dam provides a dry operating field and helps control patients.
Electrical pulp tests, cold, and heat applications can determine the vitality of unexposed pulp.
Observing for signs like nausea and vomiting may indicate overexposure to radiation.

Emergency Response

Anaphylactic shock may result from allergies to anesthetic agents; immediate medical attention is necessary.
Angina pectoris attacks might occur in patients with a history of heart problems, requiring careful management during procedures.

Dental Materials and Techniques

The least irritating cement for temporary crowns is zinc oxide-eugenol.
Removing excess cement should occur after it has hardened, using dental floss cautiously to avoid damaging interproximal areas.

Patient Observation and Diagnosis

General patient observations include assessing obesity and perspiration.
The preliminary diagnosis includes collecting physical and dental history data.

Other Key Terms

Abrasion refers to the mechanical wearing away of tooth structure.
The appropriate treatment for asthma attacks does not include having the patient breathe into a bag.
