Dental Examination

Overview: Measuring vital signs is an integral part of dental care, which can help identify health issues during a patient's visit.
Importance: Monitoring vital signs may prevent legal liability in emergencies and can determine the appropriateness of certain procedures.

Vital Signs: Measurements that inform about a patient’s physical and emotional well-being, typically including:
- Body temperature
- Pulse rate
- Breathing rate
- Blood pressure
- Smoking status (recently added)

Body Temperature: Measurement reflects the balance between heat loss and heat production.
- Influencing factors:
- Heat loss via perspiration
- Heat production through metabolism, which can be affected by illness and activity
- Diseases generally increase metabolism, while conditions like syncope or dehydration may decrease body temperature.
- Circadian Variation:
- Normal body temperature variation occurs throughout the day.
- Typically higher in the morning and lower at night.

Thermometers: Different types exist for measuring temperature including:
- Tympanic Thermometer:
- Measures internal temperature from the ear.
- Fast readings (2 seconds), comfortable with fewer infection risks.
- Use specific steps for proper usage:
  - Attach a disposable cover, insert snugly into ear canal, press read button, and beep indicates measurement completion.
- Digital Thermometer:
- Operates on battery, Fast readings (30 seconds), and disposable covers available.
- Glass Thermometer:
- Rarely used nowadays, measures mercury rise.

Normal Range: 97.6 - 99°F (36.4 - 37.3°C)
- Different measurement site readings:
- Oral: 98.6°F
- Tympanic: Average of different measurements but close to oral temperature
- Rectal: 99.6°F (higher estimate)
- Axillary: 97.6°F (lower estimate)

Important to document the taken temperature on the clinical examination form and alert the dentist of extreme values.

Pulse Definition: Rhythmic expansion and contraction of an artery as the heart beats, indicating blood circulation.
Characteristics of Pulse:
- Rhythm: Patterns like speeding up, slowing down, or irregularity.
- Rate: Number of beats in a certain time frame (normal adult rate: 60-100 beats per minute).
- Volume: Strength of the beat (strong or weak).
Conditions:
- Tachycardia: Over 100 beats/min, which can result from factors such as exercise or stimulants.
- Bradycardia: Below 50 beats/min, potentially caused by sleep or depressants.

Arteries Used for Measurement:
- Carotid: Located in the neck.
- Brachial: Located at the fold of the arm.
- Radial: Located at the wrist, near the thumb.
Document Pulse Characteristics: Record rate and any irregularities on the clinical exam form.

Definition of Respiration: The inhalation and exhalation process controlled by the brain.
Characteristics of Respiration:
- Rhythm
- Rate: Normal ranges (Adults: 10-20 breaths/min, Children: 18-30 breaths/min).
- Depth: Amount of air inhaled/exhaled.
Factors Influencing Respiration:
- Increased during physical exertion, excitement; decreased during sleep or with certain drugs.

Measuring Procedure:
- Count respirations while monitoring pulse to avoid influencing the patient's breathing pattern.
- Document respiration rate, rhythm, and depth.

Incorporates practical aspects of monitoring vital signs:
- Handling equipment, establishing rapport, and ensuring accurate measurement procedures.

Body Temperature: Wash hands, explain procedures, measure with appropriate thermometer types, document results.
Pulse Measurement: Identify the patient, choose the artery (carotid, radial, or brachial), apply proper pressure, count and document results.
Respiration Measurement: Monitor while checking pulse, establish patient rapport, and document rate, rhythm, and depth.

Complete documentation and communication with dental staff are critical after obtaining vital signs, especially if any abnormalities are noted.
