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.
