Study Notes

Hepatitis

A virus notable for its resistance to chemical and physical agents.

Anteriorly

Refers to the movement of the articular disk when the patient's mouth is opened widely.

Odontoblasts

Cells that are damaged during the overheating of an amalgam while polishing.

Juvenile Periodontitis

Associated with unique microflora and defects in polymorphonuclear leukocyte (PMN) function.

Hoes

Tools that have a significant limitation in adapting to curved surfaces.

Maxillary First Premolar

The palatal root surfaces typically exhibit longitudinal developmental grooves.

Rubella

A virus that can cross the placenta and result in congenital defects in the fetus.

Community Water Fluoridation

Public endorsements from local leaders significantly increase the likelihood of adopting this health measure.

Fluoride and Bone

A person who lived in a non-fluoridated community and moved to an area with 10ppm fluoride at age 11 may have increased fluoride stored in bones by age 35.

Essential Amino Acids

They cannot be produced in sufficient quantity by the body to meet its needs, making them essential in the diet.

Bacterial Spores

They pose a challenge in sterilization processes due to their resistance to physical and chemical agents.

Baseline Program Data

Essential for evaluating how well a dental health program meets its objectives.

Caries Prevalence

Refers to the level of untreated dental caries present in a population at a specific time.

Fluorapatite

Its resistance to tooth decay is due to its stable energy bond with calcium.

Cementum Mineralization

The mineralization of normal cementum is similar to that of bone.

Hydrocolloid Impression Material

A significant disadvantage is the lack of dimensional stability.

Periodontal Regeneration

Involves the creation of new crevicular epithelium.

Community Surveys

Interviews are the most effective method for assessing oral hygiene practices among indigent populations.

Vitamin Deficiencies

Lack of vitamins C and K can lead to abnormal hemostasis in patients.

Radial Artery

It is the most commonly used artery for checking pulse rates in conscious adults.

Humoral Immunity

Mediated by B lymphocytes.

Radiation Exposure

Standing three meters away from a radiation source reduces exposure by a factor of nine compared to standing one meter away.

Delayed Expansion of Amalgam

Caused by moisture contamination during the mixing or condensation process.

Compromised Pulmonary Function

Treating such patients involves adjusting the dental chair to a more upright position.

Space Maintainer

Its role in the mandibular arch for an 8-year-old is primarily to prevent the loss of arch space.

Epinephrine (Epi)

A sympathomimetic drug that can lead to increased blood pressure.

Hilus of the Lung

The entry point for the bronchus, pulmonary veins, arteries, and associated nerves and lymphatics into the lung.

Epithelial Attachment

Comprised of cuboidal epithelium featuring extensive keratinization.

Coronary Occlusion

A possible cause of sudden difficulty breathing and radiating pain during a dental prophylaxis.

Gingival Resilience

Primarily attributed to collagenous tissue providing firmness and resilience.

Root Planing Technique

Most effective technique employs short, even strokes followed by longer strokes.

X-ray Beam Diameter

The maximum diameter of the x-ray beam at the skin's surface should not exceed 2.75 inches.

X-ray Absorption

Long wavelength rays are more readily absorbed by the skin.

Dental Plaque

Identified as the primary cause of inflammatory periodontal disease, particularly in diabetic patients.
